-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX

-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-

-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>
-  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
-              you have headers in a nonstandard directory <include dir>
-  CXX         C++ compiler command
-  CXXFLAGS    C++ compiler flags
-  CXXCPP      C++ preprocessor
-
-Use these variables to override the choices made by `configure' or to help

-## dummy dependencies for each header file.  Too bad gcc doesn't do
-## this for us directly.
-## Some versions of gcc put a space before the ':'.  On the theory

-      Asio now provides the interfaces and functionality specified by the "C++
-      Extensions for Networking" Technical Specification. In addition to access
-      via the usual Asio header files, this functionality may be accessed through
-      special headers that correspond to the header files defined in the TS. These
-      are listed in the table below:

-<p>
-          Many asynchronous operations need to allocate an object to store state
-          associated with the operation. For example, a Win32 implementation needs
-          <code class="computeroutput"><span class="identifier">OVERLAPPED</span></code>-derived objects
-          to pass to Win32 API functions.
-        </p>
-<p>
-          Furthermore, programs typically contain easily identifiable chains of asynchronous
-          operations. A half duplex protocol implementation (e.g. an HTTP server)
-          would have a single chain of operations per client (receives followed by
-          sends). A full duplex protocol implementation would have two chains executing
-          in parallel. Programs should be able to leverage this knowledge to reuse
-          memory for all asynchronous operations in a chain.
-        </p>
-<p>
-          Given a copy of a user-defined <code class="computeroutput"><span class="identifier">Handler</span></code>
-          object <code class="computeroutput"><span class="identifier">h</span></code>, if the implementation
-          needs to allocate memory associated with that handler it will obtain an
-          allocator using the <code class="computeroutput"><span class="identifier">get_associated_allocator</span></code>
-          function. For example:
-        </p>
-<pre class="programlisting"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">associated_allocator_t</span><span class="special">&lt;</span><span class="identifier">Handler</span><span class="special">&gt;</span> <span class="identifier">a</span> <span class="special">=</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">get_associated_allocator</span><span class="special">(</span><span class="identifier">h</span><span class="special">);</span>
-</pre>
-<p>
-          The associated allocator must satisfy the standard Allocator requirements.
-        </p>
-<p>
-          By default, handlers use the standard allocator (which is implemented in
-          terms of <code class="computeroutput"><span class="special">::</span><span class="keyword">operator</span>
-          <span class="keyword">new</span><span class="special">()</span></code>
-          and <code class="computeroutput"><span class="special">::</span><span class="keyword">operator</span>
-          <span class="keyword">delete</span><span class="special">()</span></code>).
-          The allocator may be customised for a particular handler type by specifying
-          a nested type <code class="computeroutput"><span class="identifier">allocator_type</span></code>
-          and member function <code class="computeroutput"><span class="identifier">get_allocator</span><span class="special">()</span></code>:
-        </p>
-<pre class="programlisting"><span class="keyword">class</span> <span class="identifier">my_handler</span>

-          The implementation guarantees that the deallocation will occur before the
-          associated handler is invoked, which means the memory is ready to be reused
-          for any new asynchronous operations started by the handler.
-        </p>
-<p>
-          The custom memory allocation functions may be called from any user-created
-          thread that is calling a library function. The implementation guarantees
-          that, for the asynchronous operations included the library, the implementation
-          will not make concurrent calls to the memory allocation functions for that
-          handler. The implementation will insert appropriate memory barriers to
-          ensure correct memory visibility should allocation functions need to be
-          called from different threads.

-          The Asio library offers side-by-side support for synchronous and asynchronous

-          advantages and disadvantages of this approach, when compared to a synchronous-only

-            Asynchronous operation completion handlers can be written as though they

-<div class="blockquote"><blockquote class="blockquote"><p>
-            Function composition refers to the implementation of functions to provide
-            a higher-level operation, such as sending a message in a particular format.
-            Each function is implemented in terms of multiple calls to lower-level

-          </p></blockquote></div>
-<div class="blockquote"><blockquote class="blockquote"><p>
-            For example, consider a protocol where each message consists of a fixed-length

-            is specified in the header. A hypothetical read_message operation could
-            be implemented using two lower-level reads, the first to receive the

-<div class="blockquote"><blockquote class="blockquote"><p>
-            To compose functions in an asynchronous model, asynchronous operations
-            can be chained together. That is, a completion handler for one operation
-            can initiate the next. Starting the first call in the chain can be encapsulated

-          Asio may be used to perform both synchronous and asynchronous operations
-          on I/O objects such as sockets. Before using Asio it may be useful to get
-          a conceptual picture of the various parts of Asio, your program, and how
-          they work together.
-        </p>
-<p>
-          As an introductory example, let's consider what happens when you perform
-          a connect operation on a socket. We shall start by examining synchronous
-          operations.

-          <span class="bold"><strong>Your program</strong></span> will have at least one <span class="bold"><strong>I/O execution context</strong></span>, such as an <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">io_context</span></code> object, <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">thread_pool</span></code>
-          object, or <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">system_context</span></code>. This <span class="bold"><strong>I/O
-          execution context</strong></span> represents <span class="bold"><strong>your program</strong></span>'s
-          link to the <span class="bold"><strong>operating system</strong></span>'s I/O services.
-        </p>
-<pre class="programlisting"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">io_context</span> <span class="identifier">io_context</span><span class="special">;</span>
-</pre>
-<p>
-          To perform I/O operations <span class="bold"><strong>your program</strong></span>
-          will need an <span class="bold"><strong>I/O object</strong></span> such as a TCP
-          socket:
-        </p>
-<pre class="programlisting"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">ip</span><span class="special">::</span><span class="identifier">tcp</span><span class="special">::</span><span class="identifier">socket</span> <span class="identifier">socket</span><span class="special">(</span><span class="identifier">io_context</span><span class="special">);</span>
-</pre>
-<p>
-          When a synchronous connect operation is performed, the following sequence
-          of events occurs:
-        </p>
-<p>
-          1. <span class="bold"><strong>Your program</strong></span> initiates the connect
-          operation by calling the <span class="bold"><strong>I/O object</strong></span>:
-        </p>
-<pre class="programlisting"><span class="identifier">socket</span><span class="special">.</span><span class="identifier">connect</span><span class="special">(</span><span class="identifier">server_endpoint</span><span class="special">);</span>
-</pre>
-<p>
-          2. The <span class="bold"><strong>I/O object</strong></span> forwards the request
-          to the <span class="bold"><strong>I/O execution context</strong></span>.
-        </p>
-<p>
-          3. The <span class="bold"><strong>I/O execution context</strong></span> calls on
-          the <span class="bold"><strong>operating system</strong></span> to perform the connect
-          operation.
-        </p>
-<p>
-          4. The <span class="bold"><strong>operating system</strong></span> returns the result
-          of the operation to the <span class="bold"><strong>I/O execution context</strong></span>.
-        </p>
-<p>
-          5. The <span class="bold"><strong>I/O execution context</strong></span> translates
-          any error resulting from the operation into an object of type <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">error_code</span></code>. An <code class="computeroutput"><span class="identifier">error_code</span></code>
-          may be compared with specific values, or tested as a boolean (where a
-          <code class="computeroutput"><span class="keyword">false</span></code> result means that no
-          error occurred). The result is then forwarded back up to the <span class="bold"><strong>I/O object</strong></span>.
-        </p>
-<p>
-          6. The <span class="bold"><strong>I/O object</strong></span> throws an exception
-          of type <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">system_error</span></code> if the operation failed.
-          If the code to initiate the operation had instead been written as:
-        </p>
-<pre class="programlisting"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">error_code</span> <span class="identifier">ec</span><span class="special">;</span>

-<p>
-          then the <code class="computeroutput"><span class="identifier">error_code</span></code> variable
-          <code class="computeroutput"><span class="identifier">ec</span></code> would be set to the
-          result of the operation, and no exception would be thrown.
-        </p>
-<p>
-          When an asynchronous operation is used, a different sequence of events
-          occurs.
-        </p>

-<p>
-          1. <span class="bold"><strong>Your program</strong></span> initiates the connect
-          operation by calling the <span class="bold"><strong>I/O object</strong></span>:
-        </p>
-<pre class="programlisting"><span class="identifier">socket</span><span class="special">.</span><span class="identifier">async_connect</span><span class="special">(</span><span class="identifier">server_endpoint</span><span class="special">,</span> <span class="identifier">your_completion_handler</span><span class="special">);</span>
-</pre>
-<p>
-          where <code class="computeroutput"><span class="identifier">your_completion_handler</span></code>
-          is a function or function object with the signature:
-        </p>
-<pre class="programlisting"><span class="keyword">void</span> <span class="identifier">your_completion_handler</span><span class="special">(</span><span class="keyword">const</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">error_code</span><span class="special">&amp;</span> <span class="identifier">ec</span><span class="special">);</span>
-</pre>
-<p>
-          The exact signature required depends on the asynchronous operation being
-          performed. The reference documentation indicates the appropriate form for
-          each operation.
-        </p>
-<p>
-          2. The <span class="bold"><strong>I/O object</strong></span> forwards the request
-          to the <span class="bold"><strong>I/O execution context</strong></span>.
-        </p>
-<p>
-          3. The <span class="bold"><strong>I/O execution context</strong></span> signals to
-          the <span class="bold"><strong>operating system</strong></span> that it should start
-          an asynchronous connect.
-        </p>
-<p>
-          Time passes. (In the synchronous case this wait would have been contained
-          entirely within the duration of the connect operation.)
-        </p>
-<p>
-          <span class="inlinemediaobject"><img src="../../../async_op2.png" alt="async_op2"></span>
-        </p>
-<p>
-          4. The <span class="bold"><strong>operating system</strong></span> indicates that
-          the connect operation has completed by placing the result on a queue, ready
-          to be picked up by the <span class="bold"><strong>I/O execution context</strong></span>.
-        </p>
-<p>
-          5. When using an <code class="computeroutput"><span class="identifier">io_context</span></code>
-          as the <span class="bold"><strong>I/O execution context</strong></span>, <span class="bold"><strong>your program</strong></span> must make a call to <code class="computeroutput"><span class="identifier">io_context</span><span class="special">::</span><span class="identifier">run</span><span class="special">()</span></code> (or to one of the similar <code class="computeroutput"><span class="identifier">io_context</span></code> member functions) in order
-          for the result to be retrieved. A call to <code class="computeroutput"><span class="identifier">io_context</span><span class="special">::</span><span class="identifier">run</span><span class="special">()</span></code> blocks while there are unfinished asynchronous
-          operations, so you would typically call it as soon as you have started
-          your first asynchronous operation.
-        </p>
-<p>

-<p>
-          Fundamentally, I/O involves the transfer of data to and from contiguous
-          regions of memory, called buffers. These buffers can be simply expressed
-          as a tuple consisting of a pointer and a size in bytes. However, to allow
-          the development of efficient network applications, Asio includes support
-          for scatter-gather operations. These operations involve one or more buffers:
-        </p>
-<div class="itemizedlist"><ul class="itemizedlist" type="disc">
-<li class="listitem">
-              A scatter-read receives data into multiple buffers.
-            </li>
-<li class="listitem">
-              A gather-write transmits multiple buffers.
-            </li>
-</ul></div>
-<p>
-          Therefore we require an abstraction to represent a collection of buffers.
-          The approach used in Asio is to define a type (actually two types) to represent
-          a single buffer. These can be stored in a container, which may be passed
-          to the scatter-gather operations.
-        </p>
-<p>
-          In addition to specifying buffers as a pointer and size in bytes, Asio
-          makes a distinction between modifiable memory (called mutable) and non-modifiable
-          memory (where the latter is created from the storage for a const-qualified
-          variable). These two types could therefore be defined as follows:
-        </p>
-<pre class="programlisting"><span class="keyword">typedef</span> <span class="identifier">std</span><span class="special">::</span><span class="identifier">pair</span><span class="special">&lt;</span><span class="keyword">void</span><span class="special">*,</span> <span class="identifier">std</span><span class="special">::</span><span class="identifier">size_t</span><span class="special">&gt;</span> <span class="identifier">mutable_buffer</span><span class="special">;</span>
-<span class="keyword">typedef</span> <span class="identifier">std</span><span class="special">::</span><span class="identifier">pair</span><span class="special">&lt;</span><span class="keyword">const</span> <span class="keyword">void</span><span class="special">*,</span> <span class="identifier">std</span><span class="special">::</span><span class="identifier">size_t</span><span class="special">&gt;</span> <span class="identifier">const_buffer</span><span class="special">;</span>
-</pre>
-<p>
-          Here, a mutable_buffer would be convertible to a const_buffer, but conversion
-          in the opposite direction is not valid.
-        </p>
-<p>
-          However, Asio does not use the above definitions as-is, but instead defines
-          two classes: <code class="computeroutput"><span class="identifier">mutable_buffer</span></code>
-          and <code class="computeroutput"><span class="identifier">const_buffer</span></code>. The goal
-          of these is to provide an opaque representation of contiguous memory, where:
-        </p>
-<div class="itemizedlist"><ul class="itemizedlist" type="disc">
-<li class="listitem">
-              Types behave as std::pair would in conversions. That is, a <code class="computeroutput"><span class="identifier">mutable_buffer</span></code> is convertible to
-              a <code class="computeroutput"><span class="identifier">const_buffer</span></code>, but
-              the opposite conversion is disallowed.
-            </li>
-<li class="listitem">
-              There is protection against buffer overruns. Given a buffer instance,
-              a user can only create another buffer representing the same range of
-              memory or a sub-range of it. To provide further safety, the library
-              also includes mechanisms for automatically determining the size of
-              a buffer from an array, <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">array</span></code>
-              or <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">vector</span></code> of POD elements, or from a
-              <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>.

-              member function. In general an application should never need to do
-              this, but it is required by the library implementation to pass the
-              raw memory to the underlying operating system functions.
-            </li>
-</ul></div>
-<p>
-          Finally, multiple buffers can be passed to scatter-gather operations (such

-          by putting the buffer objects into a container. The <code class="computeroutput"><span class="identifier">MutableBufferSequence</span></code>
-          and <code class="computeroutput"><span class="identifier">ConstBufferSequence</span></code>
-          concepts have been defined so that containers such as <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">vector</span></code>,

-<p>
-          Some standard library implementations, such as the one that ships with
-          Microsoft Visual C++ 8.0 and later, provide a feature called iterator debugging.
-          What this means is that the validity of iterators is checked at runtime.
-          If a program tries to use an iterator that has been invalidated, an assertion
-          will be triggered. For example:
-        </p>
-<pre class="programlisting"><span class="identifier">std</span><span class="special">::</span><span class="identifier">vector</span><span class="special">&lt;</span><span class="keyword">int</span><span class="special">&gt;</span> <span class="identifier">v</span><span class="special">(</span><span class="number">1</span><span class="special">)</span>
-<span class="identifier">std</span><span class="special">::</span><span class="identifier">vector</span><span class="special">&lt;</span><span class="keyword">int</span><span class="special">&gt;::</span><span class="identifier">iterator</span> <span class="identifier">i</span> <span class="special">=</span> <span class="identifier">v</span><span class="special">.</span><span class="identifier">begin</span><span class="special">();</span>
-<span class="identifier">v</span><span class="special">.</span><span class="identifier">clear</span><span class="special">();</span> <span class="comment">// invalidates iterators</span>
-<span class="special">*</span><span class="identifier">i</span> <span class="special">=</span> <span class="number">0</span><span class="special">;</span> <span class="comment">// assertion!</span>
-</pre>
-<p>
-          Asio takes advantage of this feature to add buffer debugging. Consider
-          the following code:
-        </p>
-<pre class="programlisting"><span class="keyword">void</span> <span class="identifier">dont_do_this</span><span class="special">()</span>
-<span class="special">{</span>
- <span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span> <span class="identifier">msg</span> <span class="special">=</span> <span class="string">"Hello, world!"</span><span class="special">;</span>
- <span class="identifier">asio</span><span class="special">::</span><span class="identifier">async_write</span><span class="special">(</span><span class="identifier">sock</span><span class="special">,</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">buffer</span><span class="special">(</span><span class="identifier">msg</span><span class="special">),</span> <span class="identifier">my_handler</span><span class="special">);</span>
-<span class="special">}</span>
-</pre>
-<p>
-          When you call an asynchronous read or write you need to ensure that the
-          buffers for the operation are valid until the completion handler is called.
-          In the above example, the buffer is the <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>
-          variable <code class="computeroutput"><span class="identifier">msg</span></code>. This variable
-          is on the stack, and so it goes out of scope before the asynchronous operation
-          completes. If you're lucky then the application will crash, but random
-          failures are more likely.
-        </p>
-<p>
-          When buffer debugging is enabled, Asio stores an iterator into the string
-          until the asynchronous operation completes, and then dereferences it to
-          check its validity. In the above example you would observe an assertion
-          failure just before Asio tries to call the completion handler.
-        </p>
-<p>
-          This feature is automatically made available for Microsoft Visual Studio
-          8.0 or later and for GCC when <code class="computeroutput"><span class="identifier">_GLIBCXX_DEBUG</span></code>
-          is defined. There is a performance cost to this checking, so buffer debugging
-          is only enabled in debug builds. For other compilers it may be enabled
-          by defining <code class="computeroutput"><span class="identifier">ASIO_ENABLE_BUFFER_DEBUGGING</span></code>.
-          It can also be explicitly disabled by defining <code class="computeroutput"><span class="identifier">ASIO_DISABLE_BUFFER_DEBUGGING</span></code>.

-          The <a class="link" href="../../reference/io_context/io_context.html" title="io_context::io_context"><code class="computeroutput"><span class="identifier">io_context</span></code> constructor</a> allows

-          The <a class="link" href="../../reference/coroutine.html" title="coroutine"><code class="computeroutput">coroutine</code></a>
-          class provides support for stackless coroutines. Stackless coroutines enable
-          programs to implement asynchronous logic in a synchronous manner, with
-          minimal overhead, as shown in the following example:
-        </p>
-<pre class="programlisting">struct session : asio::coroutine
-{
-  boost::shared_ptr&lt;tcp::socket&gt; socket_;
-  boost::shared_ptr&lt;std::vector&lt;char&gt; &gt; buffer_;

-      buffer_(new std::vector&lt;char&gt;(1024))
-  {
-  }
-
-  void operator()(asio::error_code ec = asio::error_code(), std::size_t n = 0)
-  {
-    if (!ec) reenter (this)
-    {
-      for (;;)
-      {

-        yield asio::async_write(*socket_, asio::buffer(*buffer_, n), *this);
-      }
-    }
-  }
-};
-</pre>
-<p>
-          The <code class="computeroutput">coroutine</code> class is used in conjunction with the pseudo-keywords
-          <code class="computeroutput">reenter</code>, <code class="computeroutput">yield</code> and <code class="computeroutput">fork</code>. These are
-          preprocessor macros, and are implemented in terms of a <code class="computeroutput">switch</code>
-          statement using a technique similar to Duff's Device. The <a class="link" href="../../reference/coroutine.html" title="coroutine"><code class="computeroutput">coroutine</code></a>

-          Support for the Coroutines TS is provided via the <a class="link" href="../../reference/awaitable.html" title="awaitable"><code class="computeroutput">awaitable</code></a>
-          class template, the <a class="link" href="../../reference/use_awaitable_t.html" title="use_awaitable_t"><code class="computeroutput">use_awaitable</code></a>
-          completion token, and the <a class="link" href="../../reference/co_spawn.html" title="co_spawn"><code class="computeroutput">co_spawn()</code></a>
-          function. These facilities allow programs to implement asynchronous logic
-          in a synchronous manner, in conjunction with the <code class="computeroutput">co_await</code>
-          keyword, as shown in the following example:
-        </p>
-<pre class="programlisting">asio::co_spawn(executor, echo(std::move(socket)), asio::detached);
-
-// ...
-
-asio::awaitable&lt;void&gt; echo(tcp::socket socket)
-{
-  try
-  {
-    char data[1024];
-    for (;;)
-    {
-      std::size_t n = co_await socket.async_read_some(asio::buffer(data), asio::use_awaitable);
-      co_await async_write(socket, asio::buffer(data, n), asio::use_awaitable);
-    }
-  }
-  catch (std::exception&amp; e)
-  {
-    std::printf("echo Exception: %s\n", e.what());
-  }
-}
-</pre>
-<p>
-          The first argument to <code class="computeroutput">co_spawn()</code> is an <a class="link" href="../../reference/Executor1.html" title="Executor requirements">executor</a>
-          that determines the context in which the coroutine is permitted to execute.
-          For example, a server's per-client object may consist of multiple coroutines;
-          they should all run on the same <code class="computeroutput">strand</code> so that no explicit
-          synchronisation is required.
-        </p>
-<p>
-          The second argument is an <a class="link" href="../../reference/awaitable.html" title="awaitable"><code class="computeroutput">awaitable&lt;R&gt;</code></a>,
-          that is the result of the coroutine's entry point function, and in the
-          above example is the result of the call to <code class="computeroutput">echo</code>. (Alternatively,
-          this argument can be a function object that returns the <a class="link" href="../../reference/awaitable.html" title="awaitable"><code class="computeroutput">awaitable&lt;R&gt;</code></a>.)
-          The template parameter <code class="computeroutput">R</code> is the type of return value produced
-          by the coroutine. In the above example, the coroutine returns <code class="computeroutput">void</code>.
-        </p>
-<p>
-          The third argument is a completion token, and this is used by <code class="computeroutput">co_spawn()</code>
-          to produce a completion handler with signature <code class="computeroutput">void(std::exception_ptr,
-          R)</code>. This completion handler is invoked with the result of the coroutine
-          once it has finished. In the above example we pass a completion token type,
-          <a class="link" href="../../reference/detached.html" title="detached"><code class="computeroutput">asio::detached</code></a>,
-          which is used to explicitly ignore the result of an asynchronous operation.
-        </p>
-<p>
-          In this example the body of the coroutine is implemented in the <code class="computeroutput">echo</code>
-          function. When the <code class="computeroutput">use_awaitable</code> completion token is passed
-          to an asynchronous operation, the operation's initiating function returns
-          an <code class="computeroutput">awaitable</code> that may be used with the <code class="computeroutput">co_await</code>
-          keyword:
-        </p>
-<pre class="programlisting">std::size_t n = co_await socket.async_read_some(asio::buffer(data), asio::use_awaitable);
-</pre>
-<p>
-          Where an asynchronous operation's handler signature has the form:
-        </p>
-<pre class="programlisting">void handler(asio::error_code ec, result_type result);
-</pre>
-<p>
-          the resulting type of the <code class="computeroutput">co_await</code> expression is <code class="computeroutput">result_type</code>.
-          In the <code class="computeroutput">async_read_some</code> example above, this is <code class="computeroutput">size_t</code>.
-          If the asynchronous operation fails, the <code class="computeroutput">error_code</code> is converted
-          into a <code class="computeroutput">system_error</code> exception and thrown.
-        </p>
-<p>
-          Where a handler signature has the form:
-        </p>
-<pre class="programlisting">void handler(asio::error_code ec);
-</pre>
-<p>
-          the <code class="computeroutput">co_await</code> expression produces a <code class="computeroutput">void</code> result.
-          As above, an error is passed back to the coroutine as a <code class="computeroutput">system_error</code>
-          exception.

-<p>
-          To aid in debugging asynchronous programs, Asio provides support for handler
-          tracking. When enabled by defining <code class="computeroutput"><span class="identifier">ASIO_ENABLE_HANDLER_TRACKING</span></code>,
-          Asio writes debugging output to the standard error stream. The output records
-          asynchronous operations and the relationships between their handlers.
-        </p>
-<p>
-          This feature is useful when debugging and you need to know how your asynchronous
-          operations are chained together, or what the pending asynchronous operations
-          are. As an illustration, here is the output when you run the HTTP Server
-          example, handle a single request, then shut down via Ctrl+C:

-          Many commonly-used internet protocols are line-based, which means that
-          they have protocol elements that are delimited by the character sequence
-          <code class="computeroutput"><span class="string">"\r\n"</span></code>. Examples
-          include HTTP, SMTP and FTP. To more easily permit the implementation of
-          line-based protocols, as well as other protocols that use delimiters, Asio
-          includes the functions <code class="computeroutput"><span class="identifier">read_until</span><span class="special">()</span></code> and <code class="computeroutput"><span class="identifier">async_read_until</span><span class="special">()</span></code>.
-        </p>

-          The following example illustrates the use of <code class="computeroutput"><span class="identifier">async_read_until</span><span class="special">()</span></code> in an HTTP server, to receive the first

-          there may be additional data <span class="emphasis"><em>after</em></span> the delimiter.
-          This surplus data should be left in the <code class="computeroutput"><span class="identifier">streambuf</span></code>

-          Sometimes a program must be integrated with a third-party library that
-          wants to perform the I/O operations itself. To facilitate this, Asio includes
-          synchronous and asynchronous operations that may be used to wait for a
-          socket to become ready to read, ready to write, or to have a pending error
-          condition.
-        </p>
-<p>
-          As an example, to perform a non-blocking read something like the following
-          may be used:

-<p>
-          The <a class="link" href="../../reference/spawn.html" title="spawn"><code class="computeroutput">spawn()</code></a> function
-          is a high-level wrapper for running stackful coroutines. It is based on
-          the Boost.Coroutine library. The <code class="computeroutput">spawn()</code> function enables
-          programs to implement asynchronous logic in a synchronous manner, as shown
-          in the following example:
-        </p>
-<pre class="programlisting">asio::spawn(my_strand, do_echo);
-
-// ...
-
-void do_echo(asio::yield_context yield)
-{
-  try
-  {
-    char data[128];
-    for (;;)
-    {
-      std::size_t length =
-        my_socket.async_read_some(
-          asio::buffer(data), yield);
-
-      asio::async_write(my_socket,
-          asio::buffer(data, length), yield);
-    }
-  }
-  catch (std::exception&amp; e)
-  {
-    // ...
-  }
-}
-</pre>
-<p>
-          The first argument to <code class="computeroutput">spawn()</code> may be a <a class="link" href="../../reference/io_context__strand.html" title="io_context::strand"><code class="computeroutput">strand</code></a>,
-          <a class="link" href="../../reference/io_context.html" title="io_context"><code class="computeroutput">io_context</code></a>,
-          or <a class="link" href="../../reference/CompletionHandler.html" title="Completion handler requirements">completion handler</a>.
-          This argument determines the context in which the coroutine is permitted
-          to execute. For example, a server's per-client object may consist of multiple
-          coroutines; they should all run on the same <code class="computeroutput">strand</code> so that
-          no explicit synchronisation is required.
-        </p>
-<p>
-          The second argument is a function object with signature:
-        </p>
-<pre class="programlisting">void coroutine(asio::yield_context yield);
-</pre>
-<p>
-          that specifies the code to be run as part of the coroutine. The parameter
-          <code class="computeroutput">yield</code> may be passed to an asynchronous operation in place
-          of the completion handler, as in:
-        </p>
-<pre class="programlisting">std::size_t length =
-  my_socket.async_read_some(
-    asio::buffer(data), yield);
-</pre>
-<p>
-          This starts the asynchronous operation and suspends the coroutine. The
-          coroutine will be resumed automatically when the asynchronous operation
-          completes.
-        </p>
-<p>
-          Where an asynchronous operation's handler signature has the form:
-        </p>
-<pre class="programlisting">void handler(asio::error_code ec, result_type result);
-</pre>
-<p>
-          the initiating function returns the result_type. In the <code class="computeroutput">async_read_some</code>
-          example above, this is <code class="computeroutput">size_t</code>. If the asynchronous operation
-          fails, the <code class="computeroutput">error_code</code> is converted into a <code class="computeroutput">system_error</code>
-          exception and thrown.
-        </p>
-<p>
-          Where a handler signature has the form:
-        </p>
-<pre class="programlisting">void handler(asio::error_code ec);
-</pre>
-<p>
-          the initiating function returns <code class="computeroutput">void</code>. As above, an error is
-          passed back to the coroutine as a <code class="computeroutput">system_error</code> exception.
-        </p>
-<p>
-          To collect the <code class="computeroutput">error_code</code> from an operation, rather than have
-          it throw an exception, associate the output variable with the <code class="computeroutput">yield_context</code>
-          as follows:
-        </p>
-<pre class="programlisting">asio::error_code ec;
-std::size_t length =
-  my_socket.async_read_some(
-    asio::buffer(data), yield[ec]);
-</pre>
-<p>
-          <span class="bold"><strong>Note:</strong></span> if <code class="computeroutput">spawn()</code> is used
-          with a custom completion handler of type <code class="computeroutput">Handler</code>, the function
-          object signature is actually:

-              with a connection (e.g. in a half duplex protocol implementation like
-              HTTP) there is no possibility of concurrent execution of the handlers.
-              This is an implicit strand.

-              All event handler function objects need to be bound to the strand using

-              or otherwise posted/dispatched through the strand object.

-<p>
-          In the case of composed asynchronous operations, such as <code class="computeroutput"><span class="identifier">async_read</span><span class="special">()</span></code>
-          or <code class="computeroutput"><span class="identifier">async_read_until</span><span class="special">()</span></code>,
-          if a completion handler goes through a strand, then all intermediate handlers
-          should also go through the same strand. This is needed to ensure thread
-          safe access for any objects that are shared between the caller and the
-          composed operation (in the case of <code class="computeroutput"><span class="identifier">async_read</span><span class="special">()</span></code> it's the socket, which the caller can
-          <code class="computeroutput"><span class="identifier">close</span><span class="special">()</span></code>
-          to cancel the operation).
-        </p>
-<p>
-          To achieve this, all asynchronous operations obtain the handler's associated
-          executor by using the <code class="computeroutput"><span class="identifier">get_associated_executor</span></code>
-          function. For example:
-        </p>
-<pre class="programlisting"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">associated_executor_t</span><span class="special">&lt;</span><span class="identifier">Handler</span><span class="special">&gt;</span> <span class="identifier">a</span> <span class="special">=</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">get_associated_executor</span><span class="special">(</span><span class="identifier">h</span><span class="special">);</span>
-</pre>
-<p>
-          The associated executor must satisfy the Executor requirements. It will
-          be used by the asynchronous operation to submit both intermediate and final
-          handlers for execution.
-        </p>
-<p>
-          The executor may be customised for a particular handler type by specifying

-<li class="listitem">
-              must block all signals.
-            </li>
-</ul></div>
-<p>
-          This approach is complemented by the following guarantee:
-        </p>
-<div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem">
-              Asynchronous completion handlers will only be called from threads that
-              are currently calling <code class="computeroutput"><span class="identifier">io_context</span><span class="special">::</span><span class="identifier">run</span><span class="special">()</span></code>.
-            </li></ul></div>
-<p>
-          Consequently, it is the library user's responsibility to create and manage
-          all threads to which the notifications will be delivered.
-        </p>
-<p>
-          The reasons for this approach include:
-        </p>
-<div class="itemizedlist"><ul class="itemizedlist" type="disc">
-<li class="listitem">
-              By only calling <code class="computeroutput"><span class="identifier">io_context</span><span class="special">::</span><span class="identifier">run</span><span class="special">()</span></code> from a single thread, the user's
-              code can avoid the development complexity associated with synchronisation.
-              For example, a library user can implement scalable servers that are
-              single-threaded (from the user's point of view).
-            </li>
-<li class="listitem">
-              A library user may need to perform initialisation in a thread shortly
-              after the thread starts and before any other application code is executed.
-              For example, users of Microsoft's COM must call <code class="computeroutput"><span class="identifier">CoInitializeEx</span></code>
-              before any other COM operations can be called from that thread.
-            </li>
-<li class="listitem">
-              The library interface is decoupled from interfaces for thread creation
-              and management, and permits implementations on platforms where threads
-              are not available.
-            </li>

-          for returning a C++11 <code class="computeroutput">std::future</code> from an asynchronous operation's
-          initiating function.
-        </p>
-<p>
-          To use <code class="computeroutput">asio::use_future</code>, pass it to an asynchronous operation
-          instead of a normal completion handler. For example:
-        </p>
-<pre class="programlisting">std::future&lt;std::size_t&gt; length =
-  my_socket.async_read_some(my_buffer, asio::use_future);
-</pre>
-<p>
-          Where a handler signature has the form:
-        </p>
-<pre class="programlisting">void handler(asio::error_code ec, result_type result);
-</pre>
-<p>
-          the initiating function returns a <code class="computeroutput">std::future</code> templated on
-          <code class="computeroutput">result_type</code>. In the above example, this is <code class="computeroutput">std::size_t</code>.
-          If the asynchronous operation fails, the <code class="computeroutput">error_code</code> is converted
-          into a <code class="computeroutput">system_error</code> exception and passed back to the caller
-          through the future.
-        </p>
-<p>
-          Where a handler signature has the form:
-        </p>
-<pre class="programlisting">void handler(asio::error_code ec);
-</pre>
-<p>
-          the initiating function returns <code class="computeroutput">std::future&lt;void&gt;</code>. As
-          above, an error is passed back in the future as a <code class="computeroutput">system_error</code>
-          exception.

-<p>
-          With C++11 and later, user-defined completion handlers are only required
-          to be move constructible, and are not required to be copy constructible.
-        </p>
-<p>
-          When move support is enabled, asynchronous that are documented as follows:
-        </p>
-<pre class="programlisting">template &lt;typename Handler&gt;
-void async_XYZ(..., Handler handler);
-</pre>
-<p>
-          are actually declared as:
-        </p>
-<pre class="programlisting">template &lt;typename Handler&gt;
-void async_XYZ(..., Handler&amp;&amp; handler);
-</pre>
-<p>
-          The handler argument is perfectly forwarded and the move construction occurs
-          within the body of <code class="computeroutput">async_XYZ()</code>. This ensures that all other
-          function arguments are evaluated prior to the move. This is critical when
-          the other arguments to <code class="computeroutput">async_XYZ()</code> are members of the handler.
-          For example:
-        </p>
-<pre class="programlisting">struct my_operation
-{
-  unique_ptr&lt;tcp::socket&gt; socket;
-  unique_ptr&lt;vector&lt;char&gt;&gt; buffer;
-  ...
-  void operator(error_code ec, size_t length)
-  {
-    ...
-    socket-&gt;async_read_some(asio::buffer(*buffer), std::move(*this));
-    ...
-  }
-};
-</pre>
-<p>
-          Move support is automatically enabled for <code class="literal">g++</code> 4.5 and
-          later, when the <code class="literal">-std=c++0x</code> or <code class="literal">-std=gnu++0x</code>
-          compiler options are used. It may be disabled by defining <code class="computeroutput">ASIO_DISABLE_MOVE</code>,
-          or explicitly enabled for other compilers by defining <code class="computeroutput">ASIO_HAS_MOVE</code>.
-          Note that these macros also affect the availability of <a class="link" href="move_objects.html" title="Movable I/O Objects">movable

-<p>
-          When move support is available (via rvalue references), Asio allows move
-          construction and assignment of sockets, serial ports, POSIX descriptors
-          and Windows handles.
-        </p>
-<p>
-          Move support allows you to write code like:
-        </p>
-<pre class="programlisting">tcp::socket make_socket(io_context&amp; i)
-{
-  tcp::socket s(i);
-  ...
-  std::move(s);
-}
-</pre>
-<p>
-          or:
-        </p>
-<pre class="programlisting">class connection : public enable_shared_from_this&lt;connection&gt;
-{
-private:
-  tcp::socket socket_;
-  ...
-public:
-  connection(tcp::socket&amp;&amp; s) : socket_(std::move(s)) {}
-  ...
-};
-
-...
-
-class server
-{
-private:
-  tcp::acceptor acceptor_;
-  ...
-  void handle_accept(error_code ec, tcp::socket socket)
-  {
-    if (!ec)
-      std::make_shared&lt;connection&gt;(std::move(socket))-&gt;go();
-    acceptor_.async_accept(...);
-  }
-  ...
-};
-</pre>
-<p>
-          as well as:
-        </p>
-<pre class="programlisting">std::vector&lt;tcp::socket&gt; sockets;
-sockets.push_back(tcp::socket(...));
-</pre>
-<p>
-          A word of warning: There is nothing stopping you from moving these objects
-          while there are pending asynchronous operations, but it is unlikely to
-          be a good idea to do so. In particular, composed operations like <a class="link" href="../../reference/async_read.html" title="async_read">async_read()</a> store a reference
-          to the stream object. Moving during the composed operation means that the
-          composed operation may attempt to access a moved-from object.
-        </p>
-<p>
-          Move support is automatically enabled for <code class="literal">g++</code> 4.5 and
-          later, when the <code class="literal">-std=c++0x</code> or <code class="literal">-std=gnu++0x</code>

-          the <a class="link" href="../../reference/basic_socket_streambuf/connect.html" title="basic_socket_streambuf::connect">basic_socket_streambuf::connect()</a>
-          and <a class="link" href="../../reference/basic_socket_iostream/connect.html" title="basic_socket_iostream::connect">basic_socket_iostream::connect()</a>
-          functions.
-        </p>
-<p>
-          Support for variadic templates is automatically enabled for <code class="literal">g++</code>
-          4.3 and later, when the <code class="literal">-std=c++0x</code> or <code class="literal">-std=gnu++0x</code>
-          compiler options are used. It may be disabled by defining <code class="computeroutput">ASIO_DISABLE_VARIADIC_TEMPLATES</code>,
-          or explicitly enabled for other compilers by defining <code class="computeroutput">ASIO_HAS_VARIADIC_TEMPLATES</code>.

-<p>
-          The Asio library includes a low-level socket interface based on the BSD
-          socket API, which is widely implemented and supported by extensive literature.
-          It is also used as the basis for networking APIs in other languages, like
-          Java. This low-level interface is designed to support the development of
-          efficient and scalable applications. For example, it permits programmers
-          to exert finer control over the number of system calls, avoid redundant
-          data copying, minimise the use of resources like threads, and so on.
-        </p>
-<p>
-          Unsafe and error prone aspects of the BSD socket API are not included.
-          For example, the use of <code class="computeroutput">int</code> to represent all sockets lacks
-          type safety. The socket representation in Asio uses a distinct type for
-          each protocol, e.g. for TCP one would use <code class="computeroutput">ip::tcp::socket</code>,
-          and for UDP one uses <code class="computeroutput">ip::udp::socket</code>.
-        </p>
-<p>
-          The following table shows the mapping between the BSD socket API and Asio:

-<p>
-          Asio includes classes that implement iostreams on top of sockets. These
-          hide away the complexities associated with endpoint resolution, protocol
-          independence, etc. To create a connection one might simply write:
-        </p>
-<pre class="programlisting">ip::tcp::iostream stream("www.boost.org", "http");
-if (!stream)
-{
-  // Can't connect.
-}
-</pre>
-<p>
-          The iostream class can also be used in conjunction with an acceptor to
-          create simple servers. For example:
-        </p>
-<pre class="programlisting">io_context ioc;
-
-ip::tcp::endpoint endpoint(tcp::v4(), 80);
-ip::tcp::acceptor acceptor(ios, endpoint);
-
-for (;;)
-{
-  ip::tcp::iostream stream;
-  acceptor.accept(stream.socket());
-  ...
-}
-</pre>
-<p>
-          Timeouts may be set by calling <code class="computeroutput">expires_at()</code> or <code class="computeroutput">expires_from_now()</code>
-          to establish a deadline. Any socket operations that occur past the deadline
-          will put the iostream into a "bad" state.
-        </p>
-<p>
-          For example, a simple client program like this:
-        </p>
-<pre class="programlisting">ip::tcp::iostream stream;
-stream.expires_from_now(boost::posix_time::seconds(60));
-stream.connect("www.boost.org", "http");
-stream &lt;&lt; "GET /LICENSE_1_0.txt HTTP/1.0\r\n";
-stream &lt;&lt; "Host: www.boost.org\r\n";
-stream &lt;&lt; "Accept: */*\r\n";
-stream &lt;&lt; "Connection: close\r\n\r\n";
-stream.flush();
-std::cout &lt;&lt; stream.rdbuf();
-</pre>
-<p>
-          will fail if all the socket operations combined take longer than 60 seconds.
-        </p>
-<p>
-          If an error does occur, the iostream's <code class="computeroutput">error()</code> member function
-          may be used to retrieve the error code from the most recent system call:
-        </p>
-<pre class="programlisting">if (!stream)
-{
-  std::cout &lt;&lt; "Error: " &lt;&lt; stream.error().message() &lt;&lt; "\n";
-}

-            </li>
-</ul></div>
-<p>
-          These classes implement the <a class="link" href="../../reference/Protocol.html" title="Protocol requirements">protocol

-          at runtime. For example:
-        </p>
-<pre class="programlisting">asio::generic::stream_protocol::socket my_socket(my_io_context);
-my_socket.open(asio::generic::stream_protocol(AF_INET, IPPROTO_TCP));
-...
-</pre>
-<p>
-          An endpoint class template, <a class="link" href="../../reference/generic__basic_endpoint.html" title="generic::basic_endpoint"><code class="computeroutput">asio::generic::basic_endpoint</code></a>,
-          is included to support these protocol classes. This endpoint can hold any
-          other endpoint type, provided its native representation fits into a <code class="computeroutput">sockaddr_storage</code>
-          object. This class will also convert from other types that implement the

-        </p>
-<pre class="programlisting">asio::ip::tcp::endpoint my_endpoint1 = ...;
-asio::generic::stream_protocol::endpoint my_endpoint2(my_endpoint1);
-</pre>
-<p>
-          The conversion is implicit, so as to support the following use cases:
-        </p>
-<pre class="programlisting">asio::generic::stream_protocol::socket my_socket(my_io_context);
-asio::ip::tcp::endpoint my_endpoint = ...;

-          Move Construction</a>
-        </h6>
-<p>
-          When using C++11, it is possible to perform move construction from a socket
-          (or acceptor) object to convert to the more generic protocol's socket (or
-          acceptor) type. If the protocol conversion is valid:
-        </p>
-<pre class="programlisting">Protocol1 p1 = ...;
-Protocol2 p2(p1);
-</pre>
-<p>
-          then the corresponding socket conversion is allowed:
-        </p>
-<pre class="programlisting">Protocol1::socket my_socket1(my_io_context);
-...
-Protocol2::socket my_socket2(std::move(my_socket1));
-</pre>
-<p>
-          For example, one possible conversion is from a TCP socket to a generic
-          stream-oriented socket:
-        </p>
-<pre class="programlisting">asio::ip::tcp::socket my_socket1(my_io_context);
-...
-asio::generic::stream_protocol::socket my_socket2(std::move(my_socket1));
-</pre>
-<p>
-          These conversions are also available for move-assignment.
-        </p>
-<p>
-          These conversions are not limited to the above generic protocol classes.
-          User-defined protocols may take advantage of this feature by similarly
-          ensuring the conversion from <code class="computeroutput">Protocol1</code> to <code class="computeroutput">Protocol2</code>
-          is valid, as above.

-          Hostname resolution is performed using a resolver, where host and service
-          names are looked up and converted into one or more endpoints:
-        </p>
-<pre class="programlisting">ip::tcp::resolver resolver(my_io_context);

-while (iter != end)
-{
-  ip::tcp::endpoint endpoint = *iter++;
-  std::cout &lt;&lt; endpoint &lt;&lt; std::endl;
-}
-</pre>
-<p>
-          The list of endpoints obtained above could contain both IPv4 and IPv6 endpoints,
-          so a program should try each of them until it finds one that works. This
-          keeps the client program independent of a specific IP version.
-        </p>
-<p>
-          To simplify the development of protocol-independent programs, TCP clients
-          may establish connections using the free functions <a class="link" href="../../reference/connect.html" title="connect">connect()</a>
-          and <a class="link" href="../../reference/async_connect.html" title="async_connect">async_connect()</a>.
-          These operations try each endpoint in a list until the socket is successfully
-          connected. For example, a single call:
-        </p>
-<pre class="programlisting">ip::tcp::socket socket(my_io_context);
-asio::connect(socket, resolver.resolve(query));
-</pre>
-<p>
-          will synchronously try all endpoints until one is successfully connected.
-          Similarly, an asynchronous connect may be performed by writing:
-        </p>
-<pre class="programlisting">asio::async_connect(socket_, iter,
-    boost::bind(&amp;client::handle_connect, this,
-      asio::placeholders::error));
-
-// ...
-
-void handle_connect(const error_code&amp; error)
-{
-  if (!error)
-  {
-    // Start read or write operations.
-  }
-  else
-  {
-    // Handle error.
-  }
-}
-</pre>
-<p>
-          When a specific endpoint is available, a socket can be created and connected:
-        </p>
-<pre class="programlisting">ip::tcp::socket socket(my_io_context);
-socket.connect(endpoint);

-          Asio supports programs that utilise the <code class="computeroutput">fork()</code> system call.
-          Provided the program calls <code class="computeroutput">io_context.notify_fork()</code> at the
-          appropriate times, Asio will recreate any internal file descriptors (such
-          as the "self-pipe trick" descriptor used for waking up a reactor).
-          The notification is usually performed as follows:
-        </p>
-<pre class="programlisting">io_context_.notify_fork(asio::io_context::fork_prepare);
-if (fork() == 0)
-{
-  io_context_.notify_fork(asio::io_context::fork_child);
-  ...
-}
-else
-{
-  io_context_.notify_fork(asio::io_context::fork_parent);
-  ...
-}
-</pre>
-<p>
-          User-defined services can also be made fork-aware by overriding the <code class="computeroutput">io_context::service::notify_fork()</code>
-          virtual function.
-        </p>
-<p>
-          Note that any file descriptors accessible via Asio's public API (e.g. the
-          descriptors underlying <code class="computeroutput">basic_socket&lt;&gt;</code>, <code class="computeroutput">posix::stream_descriptor</code>,
-          etc.) are not altered during a fork. It is the program's responsibility
-          to manage these as required.

-<p>
-          Asio provides basic support for UNIX domain sockets (also known as local
-          sockets). The simplest use involves creating a pair of connected sockets.
-          The following code:
-        </p>
-<pre class="programlisting">local::stream_protocol::socket socket1(my_io_context);
-local::stream_protocol::socket socket2(my_io_context);
-local::connect_pair(socket1, socket2);
-</pre>
-<p>
-          will create a pair of stream-oriented sockets. To do the same for datagram-oriented
-          sockets, use:
-        </p>
-<pre class="programlisting">local::datagram_protocol::socket socket1(my_io_context);
-local::datagram_protocol::socket socket2(my_io_context);
-local::connect_pair(socket1, socket2);
-</pre>
-<p>
-          A UNIX domain socket server may be created by binding an acceptor to an
-          endpoint, in much the same way as one does for a TCP server:
-        </p>
-<pre class="programlisting">::unlink("/tmp/foobar"); // Remove previous binding.
-local::stream_protocol::endpoint ep("/tmp/foobar");
-local::stream_protocol::acceptor acceptor(my_io_context, ep);
-local::stream_protocol::socket socket(my_io_context);
-acceptor.accept(socket);
-</pre>
-<p>
-          A client that connects to this server might look like:
-        </p>
-<pre class="programlisting">local::stream_protocol::endpoint ep("/tmp/foobar");
-local::stream_protocol::socket socket(my_io_context);
-socket.connect(ep);
-</pre>
-<p>
-          Transmission of file descriptors or credentials across UNIX domain sockets
-          is not directly supported within Asio, but may be achieved by accessing
-          the socket's underlying descriptor using the <a class="link" href="../../reference/basic_socket/native_handle.html" title="basic_socket::native_handle">native_handle()</a>
-          member function.

-          Asio includes classes added to permit synchronous and asynchronous read
-          and write operations to be performed on POSIX file descriptors, such as
-          pipes, standard input and output, and various devices.
-        </p>
-<p>
-          These classes also provide limited support for regular files. This support
-          assumes that the underlying read and write operations provided by the operating
-          system never fail with <code class="computeroutput">EAGAIN</code> or <code class="computeroutput">EWOULDBLOCK</code>.
-          (This assumption normally holds for buffered file I/O.) Synchronous and
-          asynchronous read and write operations on file descriptors will succeed
-          but the I/O will always be performed immediately. Wait operations, and
-          operations involving <code class="computeroutput">asio::null_buffers</code>, are not portably
-          supported.
-        </p>
-<p>
-          For example, to perform read and write operations on standard input and
-          output, the following objects may be created:
-        </p>
-<pre class="programlisting">posix::stream_descriptor in(my_io_context, ::dup(STDIN_FILENO));
-posix::stream_descriptor out(my_io_context, ::dup(STDOUT_FILENO));
-</pre>
-<p>
-          These are then used as synchronous or asynchronous read and write streams.
-          This means the objects can be used with any of the <a class="link" href="../../reference/read.html" title="read">read()</a>,
-          <a class="link" href="../../reference/async_read.html" title="async_read">async_read()</a>, <a class="link" href="../../reference/write.html" title="write">write()</a>,

-<p>
-        Most programs interact with the outside world in some way, whether it be
-        via a file, a network, a serial cable, or the console. Sometimes, as is the
-        case with networking, individual I/O operations can take a long time to complete.
-        This poses particular challenges to application development.
-      </p>
-<p>
-        Asio provides the tools to manage these long running operations, without
-        requiring programs to use concurrency models based on threads and explicit
-        locking.
-      </p>
-<p>
-        The Asio library is intended for programmers using C++ for systems programming,
-        where access to operating system functionality such as networking is often
-        required. In particular, Asio addresses the following goals:
-      </p>
-<div class="itemizedlist"><ul class="itemizedlist" type="disc">
-<li class="listitem">
-            <span class="bold"><strong>Portability.</strong></span> The library should support
-            a range of commonly used operating systems, and provide consistent behaviour
-            across these operating systems.
-          </li>
-<li class="listitem">
-            <span class="bold"><strong>Scalability.</strong></span> The library should facilitate
-            the development of network applications that scale to thousands of concurrent
-            connections. The library implementation for each operating system should
-            use the mechanism that best enables this scalability.
-          </li>
-<li class="listitem">
-            <span class="bold"><strong>Efficiency.</strong></span> The library should support
-            techniques such as scatter-gather I/O, and allow programs to minimise
-            data copying.
-          </li>
-<li class="listitem">
-            <span class="bold"><strong>Model concepts from established APIs, such as BSD
-            sockets.</strong></span> The BSD socket API is widely implemented and understood,
-            and is covered in much literature. Other programming languages often
-            use a similar interface for networking APIs. As far as is reasonable,
-            Asio should leverage existing practice.
-          </li>
-<li class="listitem">
-            <span class="bold"><strong>Ease of use.</strong></span> The library should provide
-            a lower entry barrier for new users by taking a toolkit, rather than
-            framework, approach. That is, it should try to minimise the up-front
-            investment in time to just learning a few basic rules and guidelines.
-            After that, a library user should only need to understand the specific
-            functions that are being used.
-          </li>
-<li class="listitem">
-            <span class="bold"><strong>Basis for further abstraction.</strong></span> The library
-            should permit the development of other libraries that provide higher

-            protocols such as HTTP.
-          </li>
-</ul></div>
-<p>
-        Although Asio started life focused primarily on networking, its concepts
-        of asynchronous I/O have been extended to include other operating system
-        resources such as serial ports, file descriptors, and so on.

-        Asio includes classes for creating and manipulating serial ports in a portable

-<pre class="programlisting">serial_port port(my_io_context, name);

-      </p>
-<p>

-        Asio supports signal handling using a class called <a class="link" href="../reference/signal_set.html" title="signal_set">signal_set</a>.
-        Programs may add one or more signals to the set, and then perform an <code class="computeroutput">async_wait()</code>
-        operation. The specified handler will be called when one of the signals occurs.
-        The same signal number may be registered with multiple <a class="link" href="../reference/signal_set.html" title="signal_set">signal_set</a>
-        objects, however the signal number must be used only with Asio.

-<p>
-        Asio contains classes and class templates for basic SSL support. These classes
-        allow encrypted communication to be layered on top of an existing stream,
-        such as a TCP socket.
-      </p>
-<p>
-        Before creating an encrypted stream, an application must construct an SSL
-        context object. This object is used to set SSL options such as verification
-        mode, certificate files, and so on. As an illustration, client-side initialisation
-        may look something like:
-      </p>
-<pre class="programlisting">ssl::context ctx(ssl::context::sslv23);
-ctx.set_verify_mode(ssl::verify_peer);
-ctx.load_verify_file("ca.pem");
-</pre>
-<p>
-        To use SSL with a TCP socket, one may write:
-      </p>
-<pre class="programlisting">ssl::stream&lt;ip::tcp::socket&gt; ssl_sock(my_io_context, ctx);
-</pre>
-<p>
-        To perform socket-specific operations, such as establishing an outbound connection
-        or accepting an incoming one, the underlying socket must first be obtained
-        using the <code class="computeroutput">ssl::stream</code> template's <a class="link" href="../reference/ssl__stream/lowest_layer.html" title="ssl::stream::lowest_layer"><code class="computeroutput">lowest_layer()</code></a>
-        member function:
-      </p>
-<pre class="programlisting">ip::tcp::socket::lowest_layer_type&amp; sock = ssl_sock.lowest_layer();
-sock.connect(my_endpoint);
-</pre>
-<p>
-        In some use cases the underlying stream object will need to have a longer
-        lifetime than the SSL stream, in which case the template parameter should
-        be a reference to the stream type:
-      </p>
-<pre class="programlisting">ip::tcp::socket sock(my_io_context);
-ssl::stream&lt;ip::tcp::socket&amp;&gt; ssl_sock(sock, ctx);
-</pre>
-<p>
-        SSL handshaking must be performed prior to transmitting or receiving data
-        over an encrypted connection. This is accomplished using the <code class="computeroutput">ssl::stream</code>
-        template's <a class="link" href="../reference/ssl__stream/handshake.html" title="ssl::stream::handshake">handshake()</a>
-        or <a class="link" href="../reference/ssl__stream/async_handshake.html" title="ssl::stream::async_handshake">async_handshake()</a>
-        member functions.
-      </p>
-<p>
-        Once connected, SSL stream objects are used as synchronous or asynchronous
-        read and write streams. This means the objects can be used with any of the
-        <a class="link" href="../reference/read.html" title="read">read()</a>, <a class="link" href="../reference/async_read.html" title="async_read">async_read()</a>,

-        Long running I/O operations will often have a deadline by which they must
-        have completed. These deadlines may be expressed as absolute times, but are
-        often calculated relative to the current time.
-      </p>
-<p>
-        As a simple example, to perform a synchronous wait operation on a timer using
-        a relative time one may write:
-      </p>
-<pre class="programlisting">io_context i;
-...
-deadline_timer t(i);
-t.expires_from_now(boost::posix_time::seconds(5));
-t.wait();
-</pre>
-<p>
-        More commonly, a program will perform an asynchronous wait operation on a
-        timer:
-      </p>
-<pre class="programlisting">void handler(asio::error_code ec) { ... }
-...
-io_context i;
-...
-deadline_timer t(i);
-t.expires_from_now(boost::posix_time::milliseconds(400));
-t.async_wait(handler);
-...
-i.run();
-</pre>

-          Asio contains classes to allow asynchronous read and write operations to
-          be performed on Windows <code class="computeroutput">HANDLE</code>s, such as named pipes.
-        </p>
-<p>
-          For example, to perform asynchronous operations on a named pipe, the following
-          object may be created:
-        </p>
-<pre class="programlisting">HANDLE handle = ::CreateFile(...);
-windows::stream_handle pipe(my_io_context, handle);
-</pre>
-<p>
-          These are then used as synchronous or asynchronous read and write streams.
-          This means the objects can be used with any of the <a class="link" href="../../reference/read.html" title="read">read()</a>,
-          <a class="link" href="../../reference/async_read.html" title="async_read">async_read()</a>, <a class="link" href="../../reference/write.html" title="write">write()</a>,
-          <a class="link" href="../../reference/async_write.html" title="async_write">async_write()</a>, <a class="link" href="../../reference/read_until.html" title="read_until">read_until()</a> or <a class="link" href="../../reference/async_read_until.html" title="async_read_until">async_read_until()</a>
-          free functions.
-        </p>
-<p>
-          The kernel object referred to by the <code class="computeroutput">HANDLE</code> must support use
-          with I/O completion ports (which means that named pipes are supported,
-          but anonymous pipes and console streams are not).

-        A dynamic buffer encapsulates memory storage that may be automatically resized
-        as required, where the memory is divided into an input sequence followed
-        by an output sequence. These memory regions are internal to the dynamic buffer
-        sequence, but direct access to the elements is provided to permit them to
-        be efficiently used with I/O operations, such as the <code class="computeroutput">send</code> or
-        <code class="computeroutput">receive</code> operations of a socket. Data written to the output sequence
-        of a dynamic buffer sequence object is appended to the input sequence of
-        the same object.
-      </p>

-        A dynamic buffer type <code class="computeroutput">X</code> shall satisfy the requirements of <code class="computeroutput">MoveConstructible</code>

-        A receiver represents the continuation of an asynchronous operation. An asynchronous
-        operation may complete with a (possibly empty) set of values, an error, or
-        it may be cancelled. A receiver has three principal operations corresponding
-        to the three ways an asynchronous operation may complete: <code class="computeroutput">set_value</code>,
-        <code class="computeroutput">set_error</code>, and <code class="computeroutput">set_done</code>. These are collectively
-        known as a receiver’s <span class="emphasis"><em>completion-signal operations</em></span>.

-</pre>
-<p>
-        The receiver’s completion-signal operations have semantic requirements

-            state object that was returned by <code class="computeroutput">execution::connect</code> to
-            connect that receiver to a sender.
-          </li>
-<li class="listitem">
-            Once <code class="computeroutput">execution::start</code> has been called on the operation state
-            object, exactly one of the receiver’s completion-signal operations
-            shall complete non-exceptionally before the receiver is destroyed.
-          </li>
-<li class="listitem">
-            If <code class="computeroutput">execution::set_value</code> exits with an exception, it is still
-            valid to call <code class="computeroutput">execution::set_error</code> or <code class="computeroutput">execution::set_done</code>
-            on the receiver.
-          </li>
-</ul></div>

-        The <code class="computeroutput">basic_waitable_timer</code> template uses wait traits to allow

-        [<span class="emphasis"><em>Note:</em></span> Possible uses of wait traits include:<br> — To
-        enable timers based on non-realtime clocks.<br> — Determining how quickly
-        wallclock-based timers respond to system time changes.<br> — Correcting for
-        errors or rounding timeouts to boundaries.<br> — Preventing duration overflow.
-        That is, a program may set a timer's expiry <code class="computeroutput">e</code> to be <code class="computeroutput">Clock::max()</code>
-        (meaning never reached) or <code class="computeroutput">Clock::min()</code> (meaning always in the

-        When asynchronous operations are composed from other asynchronous operations,
-        all intermediate handlers should be invoked using the same method as the
-        final handler. This is required to ensure that user-defined objects are not
-        accessed in a way that may violate the guarantees. This hooking function
-        ensures that the invoked method used for the final handler is accessible
-        at each intermediate step.
-      </p>
-<p>
-        Implement asio_handler_invoke for your own handlers to specify a custom invocation
-        strategy.
-      </p>
-<p>
-        This default implementation invokes the function object like so:
-      </p>
-<pre class="programlisting">function();
-</pre>
-<p>
-        If necessary, the default implementation makes a copy of the function object
-        so that the non-const operator() can be used.
-      </p>

-<pre class="programlisting">void handler(
-  // Result of operation.
-  const asio::error_code&amp; error,

-                Regardless of whether the asynchronous operation completes immediately
-                or not, the handler will not be invoked from within this function.
-                On immediate completion, invocation of the handler will be performed

-<p>
-        An <span class="emphasis"><em>initiating function</em></span> is a function which may be called
-        to start an asynchronous operation. A <span class="emphasis"><em>completion handler</em></span>
-        is a function object that will be invoked, at most once, with the result
-        of the asynchronous operation.
-      </p>
-<p>
-        The lifecycle of an asynchronous operation is comprised of the following
-        events and phases:
-      </p>
-<p>
-        — Event 1: The asynchronous operation is started by a call to the initiating
-        function.
-      </p>
-<p>
-        — Phase 1: The asynchronous operation is now <span class="emphasis"><em>outstanding</em></span>.
-      </p>
-<p>
-        — Event 2: The externally observable side effects of the asynchronous operation,
-        if any, are fully established. The completion handler is submitted to an
-        executor.
-      </p>
-<p>
-        — Phase 2: The asynchronous operation is now <span class="emphasis"><em>completed</em></span>.
-      </p>
-<p>
-        — Event 3: The completion handler is called with the result of the asynchronous
-        operation.
-      </p>
-<p>
-        In this library, all functions with the prefix <code class="computeroutput">async_</code> are initiating
-        functions.

-      </p>
-<p>
-        An initiating function determines the type <code class="computeroutput">CompletionHandler</code>
-        of its completion handler function object by performing <code class="computeroutput">typename async_result&lt;decay_t&lt;CompletionToken&gt;,

-        (C++Std [moveconstructible]), and be callable with the specified call signature.
-      </p>
-<p>
-        In this library, all initiating functions specify a <span class="emphasis"><em>Completion

-        The <span class="emphasis"><em>Completion signature</em></span> elements in this Technical

-        so that it may be used as shown in the following example:
-      </p>
-<pre class="programlisting">auto socket = use_awaitable.as_default_on(tcp::socket(my_context));
-// ...
-co_await socket.async_connect(my_endpoint); // Defaults to use_awaitable.

-        from <code class="computeroutput">tcp::socket</code> to have an I/O executor with the default completion
-        token set to <code class="computeroutput">use_awaitable</code>.
-      </p>
-<p>
-        Alternatively, the socket type may be computed directly:

-<pre class="programlisting">using tcp_socket = use_awaitable_t&lt;&gt;::as_default_on_t&lt;tcp::socket&gt;;
-tcp_socket socket(my_context);

-            when run on Windows XP, Windows Server 2003, and earlier versions of
-            Windows, unless ASIO_ENABLE_CANCELIO is defined. However, the CancelIo

-<li class="listitem">
-                It can appear to complete without error, but the request to cancel
-                the unfinished operations may be silently ignored by the operating

-                are installed.
-              </li>
-</ul></div>
-<p>
-            For portable cancellation, consider using one of the following alternatives:
-          </p>
-<div class="itemizedlist"><ul class="itemizedlist" type="disc">
-<li class="listitem">
-                Disable asio's I/O completion port backend by defining ASIO_DISABLE_IOCP.

-<li class="listitem">

-                outstanding operations and close the socket.
-              </li>
-</ul></div>
-<p>
-            When running on Windows Vista, Windows Server 2008, and later, the CancelIoEx
-            function is always used. This function does not have the problems described
-            above.

-              </li>
-</ul></div>
-<p>
-            For portable cancellation, consider using one of the following alternatives:
-          </p>
-<div class="itemizedlist"><ul class="itemizedlist" type="disc">
-<li class="listitem">
-                Disable asio's I/O completion port backend by defining ASIO_DISABLE_IOCP.

-<li class="listitem">

-              </li>
-</ul></div>
-<p>
-            For portable cancellation, consider using one of the following alternatives:

-            When running on Windows Vista, Windows Server 2008, and later, the CancelIoEx

-        Note that multiple registration only works for signals that are registered

-        The <code class="computeroutput">basic_streambuf</code> class is derived from <code class="computeroutput">std::streambuf</code>
-        to associate the streambuf's input and output sequences with one or more
-        character arrays. These character arrays are internal to the <code class="computeroutput">basic_streambuf</code>
-        object, but direct access to the array elements is provided to permit them
-        to be used efficiently with I/O operations. Characters written to the output
-        sequence of a <code class="computeroutput">basic_streambuf</code> object are appended to the input
-        sequence of the same object.
-      </p>
-<p>
-        The <code class="computeroutput">basic_streambuf</code> class's public interface is intended to
-        permit the following implementation strategies:
-      </p>
-<div class="itemizedlist"><ul class="itemizedlist" type="disc">
-<li class="listitem">
-            A single contiguous character array, which is reallocated as necessary
-            to accommodate changes in the size of the character sequence. This is
-            the implementation approach currently used in Asio.
-          </li>
-<li class="listitem">
-            A sequence of one or more character arrays, where each array is of the
-            same size. Additional character array objects are appended to the sequence
-            to accommodate changes in the size of the character sequence.
-          </li>
-<li class="listitem">
-            A sequence of one or more character arrays of varying sizes. Additional
-            character array objects are appended to the sequence to accommodate changes

-        The constructor for <a class="link" href="basic_streambuf.html" title="basic_streambuf"><code class="computeroutput">basic_streambuf</code></a>
-        accepts a <code class="computeroutput">size_t</code> argument specifying the maximum of the sum
-        of the sizes of the input sequence and output sequence. During the lifetime
-        of the <code class="computeroutput">basic_streambuf</code> object, the following invariant holds:
-      </p>
-<pre class="programlisting">size() &lt;= max_size()
-</pre>
-<p>
-        Any member function that would, if successful, cause the invariant to be
-        violated shall throw an exception of class <code class="computeroutput">std::length_error</code>.
-      </p>
-<p>
-        The constructor for <code class="computeroutput">basic_streambuf</code> takes an Allocator argument.
-        A copy of this argument is used for any memory allocation performed, by the
-        constructor and by all member functions, during the lifetime of each <code class="computeroutput">basic_streambuf</code>

-          The <code class="computeroutput">basic_streambuf</code> class is derived from <code class="computeroutput">std::streambuf</code>
-          to associate the streambuf's input and output sequences with one or more
-          character arrays. These character arrays are internal to the <code class="computeroutput">basic_streambuf</code>
-          object, but direct access to the array elements is provided to permit them
-          to be used efficiently with I/O operations. Characters written to the output
-          sequence of a <code class="computeroutput">basic_streambuf</code> object are appended to the input
-          sequence of the same object.
-        </p>
-<p>
-          The <code class="computeroutput">basic_streambuf</code> class's public interface is intended to

-<div class="itemizedlist"><ul class="itemizedlist" type="disc">
-<li class="listitem">
-              A single contiguous character array, which is reallocated as necessary
-              to accommodate changes in the size of the character sequence. This
-              is the implementation approach currently used in Asio.
-            </li>
-<li class="listitem">
-              A sequence of one or more character arrays, where each array is of
-              the same size. Additional character array objects are appended to the
-              sequence to accommodate changes in the size of the character sequence.
-            </li>
-<li class="listitem">
-              A sequence of one or more character arrays of varying sizes. Additional
-              character array objects are appended to the sequence to accommodate

-          The constructor for <a class="link" href="../basic_streambuf.html" title="basic_streambuf"><code class="computeroutput">basic_streambuf</code></a>

-          of the sizes of the input sequence and output sequence. During the lifetime
-          of the <code class="computeroutput">basic_streambuf</code> object, the following invariant holds:
-        </p>
-<pre class="programlisting">size() &lt;= max_size()
-</pre>
-<p>
-          Any member function that would, if successful, cause the invariant to be

-        </p>
-<p>
-          The constructor for <code class="computeroutput">basic_streambuf</code> takes an Allocator argument.
-          A copy of this argument is used for any memory allocation performed, by

-          The <code class="computeroutput">basic_streambuf</code> class is derived from <code class="computeroutput">std::streambuf</code>
-          to associate the streambuf's input and output sequences with one or more
-          character arrays. These character arrays are internal to the <code class="computeroutput">basic_streambuf</code>
-          object, but direct access to the array elements is provided to permit them
-          to be used efficiently with I/O operations. Characters written to the output
-          sequence of a <code class="computeroutput">basic_streambuf</code> object are appended to the input
-          sequence of the same object.

-<li class="listitem">

-        The system executor represents an execution context where functions are permitted
-        to run on arbitrary threads. When the blocking.never property is established,
-        the system executor will schedule the function to run on an unspecified system
-        thread pool. When either blocking.possibly or blocking.always is established,
-        the executor invokes the function immediately.

-        A buffer object represents a contiguous region of memory as a 2-tuple consisting
-        of a pointer and size in bytes. A tuple of the form <code class="computeroutput">{void*, size_t}</code>
-        specifies a mutable (modifiable) region of memory. Similarly, a tuple of
-        the form <code class="computeroutput">{const void*, size_t}</code> specifies a const (non-modifiable)
-        region of memory. These two forms correspond to the classes <a class="link" href="mutable_buffer.html" title="mutable_buffer"><code class="computeroutput">mutable_buffer</code></a>
-        and <a class="link" href="const_buffer.html" title="const_buffer"><code class="computeroutput">const_buffer</code></a>,
-        respectively. To mirror C++'s conversion rules, a <a class="link" href="mutable_buffer.html" title="mutable_buffer"><code class="computeroutput">mutable_buffer</code></a>
-        is implicitly convertible to a <a class="link" href="const_buffer.html" title="const_buffer"><code class="computeroutput">const_buffer</code></a>,
-        and the opposite conversion is not permitted.
-      </p>
-<p>
-        The simplest use case involves reading or writing a single buffer of a specified
-        size:
-      </p>
-<pre class="programlisting">sock.send(asio::buffer(data, size));
-</pre>
-<p>
-        In the above example, the return value of <code class="computeroutput">asio::buffer</code> meets
-        the requirements of the ConstBufferSequence concept so that it may be directly
-        passed to the socket's write function. A buffer created for modifiable memory
-        also meets the requirements of the MutableBufferSequence concept.
-      </p>
-<p>
-        An individual buffer may be created from a builtin array, std::vector, std::array
-        or boost::array of POD elements. This helps prevent buffer overruns by automatically
-        determining the size of the buffer:
-      </p>
-<pre class="programlisting">char d1[128];
-size_t bytes_transferred = sock.receive(asio::buffer(d1));
-
-std::vector&lt;char&gt; d2(128);
-bytes_transferred = sock.receive(asio::buffer(d2));
-
-std::array&lt;char, 128&gt; d3;
-bytes_transferred = sock.receive(asio::buffer(d3));
-
-boost::array&lt;char, 128&gt; d4;
-bytes_transferred = sock.receive(asio::buffer(d4));
-</pre>
-<p>
-        In all three cases above, the buffers created are exactly 128 bytes long.
-        Note that a vector is <span class="emphasis"><em>never</em></span> automatically resized when
-        creating or using a buffer. The buffer size is determined using the vector's
-        <code class="computeroutput">size()</code> member function, and not its capacity.
-      </p>

-        For convenience, a <a class="link" href="buffer_size.html" title="buffer_size"><code class="computeroutput">buffer_size</code></a>

-<p>
-        A buffer object does not have any ownership of the memory it refers to. It

-        For the <code class="computeroutput">asio::buffer</code> overloads that accept an argument of type

-      </h5>
-<p>
-        Buffer objects may be manipulated using simple arithmetic in a safe way which
-        helps prevent buffer overruns. Consider an array initialised as follows:
-      </p>
-<pre class="programlisting">boost::array&lt;char, 6&gt; a = { 'a', 'b', 'c', 'd', 'e' };
-</pre>
-<p>
-        A buffer object <code class="computeroutput">b1</code> created using:
-      </p>
-<pre class="programlisting">b1 = asio::buffer(a);
-</pre>
-<p>
-        represents the entire array, <code class="computeroutput">{ 'a', 'b', 'c', 'd', 'e' }</code>. An
-        optional second argument to the <code class="computeroutput">asio::buffer</code> function may be
-        used to limit the size, in bytes, of the buffer:
-      </p>
-<pre class="programlisting">b2 = asio::buffer(a, 3);
-</pre>
-<p>
-        such that <code class="computeroutput">b2</code> represents the data <code class="computeroutput">{ 'a', 'b', 'c' }</code>.
-        Even if the size argument exceeds the actual size of the array, the size
-        of the buffer object created will be limited to the array size.
-      </p>
-<p>
-        An offset may be applied to an existing buffer to create a new one:
-      </p>
-<pre class="programlisting">b3 = b1 + 2;
-</pre>
-<p>
-        where <code class="computeroutput">b3</code> will set to represent <code class="computeroutput">{ 'c', 'd', 'e' }</code>.
-        If the offset exceeds the size of the existing buffer, the newly created
-        buffer will be empty.
-      </p>
-<p>
-        Both an offset and size may be specified to create a buffer that corresponds
-        to a specific range of bytes within an existing buffer:
-      </p>
-<pre class="programlisting">b4 = asio::buffer(b1 + 1, 3);
-</pre>
-<p>
-        so that <code class="computeroutput">b4</code> will refer to the bytes <code class="computeroutput">{ 'b', 'c', 'd' }</code>.

-        The <code class="computeroutput">coroutine</code> class may be used to implement stackless coroutines.
-        The class itself is used to store the current state of the coroutine.
-      </p>
-<p>
-        Coroutines are copy-constructible and assignable, and the space overhead
-        is a single int. They can be used as a base class:
-      </p>
-<pre class="programlisting">class session : coroutine
-{
-  ...
-};
-</pre>
-<p>
-        or as a data member:
-      </p>
-<pre class="programlisting">class session
-{
-  ...
-  coroutine coro_;
-};
-</pre>
-<p>
-        or even bound in as a function argument using lambdas or <code class="computeroutput">bind()</code>.
-        The important thing is that as the application maintains a copy of the object
-        for as long as the coroutine must be kept alive.
-      </p>
-<h5>
-<a name="asio.reference.coroutine.h1"></a>
-        <span><a name="asio.reference.coroutine.pseudo_keywords"></a></span><a class="link" href="coroutine.html#asio.reference.coroutine.pseudo_keywords">Pseudo-keywords</a>
-      </h5>
-<p>
-        A coroutine is used in conjunction with certain "pseudo-keywords",
-        which are implemented as macros. These macros are defined by a header file:
-      </p>
-<pre class="programlisting">#include &lt;asio/yield.hpp&gt;
-</pre>
-<p>
-        and may conversely be undefined as follows:
-      </p>
-<pre class="programlisting">#include &lt;asio/unyield.hpp&gt;
-</pre>
-<p>
-        <span class="bold"><strong>reenter</strong></span>
-      </p>
-<p>
-        The <code class="computeroutput">reenter</code> macro is used to define the body of a coroutine.
-        It takes a single argument: a pointer or reference to a coroutine object.
-        For example, if the base class is a coroutine object you may write:
-      </p>
-<pre class="programlisting">reenter (this)
-{
-  ... coroutine body ...
-}
-</pre>
-<p>
-        and if a data member or other variable you can write:
-      </p>
-<pre class="programlisting">reenter (coro_)
-{
-  ... coroutine body ...
-}
-</pre>
-<p>
-        When <code class="computeroutput">reenter</code> is executed at runtime, control jumps to the location
-        of the last <code class="computeroutput">yield</code> or <code class="computeroutput">fork</code>.
-      </p>
-<p>
-        The coroutine body may also be a single statement, such as:
-      </p>
-<pre class="programlisting">reenter (this) for (;;)
-{
-  ...
-}
-</pre>
-<p>
-        <span class="bold"><strong>Limitation:</strong></span> The <code class="computeroutput">reenter</code> macro
-        is implemented using a switch. This means that you must take care when using
-        local variables within the coroutine body. The local variable is not allowed
-        in a position where reentering the coroutine could bypass the variable definition.
-      </p>
-<p>
-        <span class="bold"><strong>yield <span class="emphasis"><em>statement</em></span></strong></span>
-      </p>
-<p>
-        This form of the <code class="computeroutput">yield</code> keyword is often used with asynchronous
-        operations:
-      </p>
-<pre class="programlisting">yield socket_-&gt;async_read_some(buffer(*buffer_), *this);
-</pre>
-<p>
-        This divides into four logical steps:
-      </p>
-<div class="itemizedlist"><ul class="itemizedlist" type="disc">
-<li class="listitem">
-            <code class="computeroutput">yield</code> saves the current state of the coroutine.
-          </li>
-<li class="listitem">
-            The statement initiates the asynchronous operation.
-          </li>
-<li class="listitem">
-            The resume point is defined immediately following the statement.
-          </li>
-<li class="listitem">
-            Control is transferred to the end of the coroutine body.
-          </li>
-</ul></div>
-<p>
-        When the asynchronous operation completes, the function object is invoked
-        and <code class="computeroutput">reenter</code> causes control to transfer to the resume point.
-        It is important to remember to carry the coroutine state forward with the
-        asynchronous operation. In the above snippet, the current class is a function
-        object object with a coroutine object as base class or data member.
-      </p>
-<p>
-        The statement may also be a compound statement, and this permits us to define
-        local variables with limited scope:
-      </p>
-<pre class="programlisting">yield
-{
-  mutable_buffers_1 b = buffer(*buffer_);
-  socket_-&gt;async_read_some(b, *this);
-}
-</pre>
-<p>
-        <span class="bold"><strong>yield return <span class="emphasis"><em>expression</em></span> ;</strong></span>
-      </p>
-<p>
-        This form of <code class="computeroutput">yield</code> is often used in generators or coroutine-based
-        parsers. For example, the function object:
-      </p>
-<pre class="programlisting">struct interleave : coroutine
-{
-  istream&amp; is1;
-  istream&amp; is2;
-  char operator()(char c)
-  {
-    reenter (this) for (;;)
-    {
-      yield return is1.get();
-      yield return is2.get();
-    }
-  }
-};
-</pre>
-<p>
-        defines a trivial coroutine that interleaves the characters from two input
-        streams.
-      </p>
-<p>
-        This type of <code class="computeroutput">yield</code> divides into three logical steps:
-      </p>
-<div class="itemizedlist"><ul class="itemizedlist" type="disc">
-<li class="listitem">
-            <code class="computeroutput">yield</code> saves the current state of the coroutine.
-          </li>
-<li class="listitem">
-            The resume point is defined immediately following the semicolon.
-          </li>
-<li class="listitem">
-            The value of the expression is returned from the function.
-          </li>
-</ul></div>
-<p>
-        <span class="bold"><strong>yield ;</strong></span>
-      </p>
-<p>
-        This form of <code class="computeroutput">yield</code> is equivalent to the following steps:
-      </p>
-<div class="itemizedlist"><ul class="itemizedlist" type="disc">
-<li class="listitem">
-            <code class="computeroutput">yield</code> saves the current state of the coroutine.
-          </li>
-<li class="listitem">
-            The resume point is defined immediately following the semicolon.
-          </li>
-<li class="listitem">
-            Control is transferred to the end of the coroutine body.
-          </li>
-</ul></div>
-<p>
-        This form might be applied when coroutines are used for cooperative threading
-        and scheduling is explicitly managed. For example:
-      </p>
-<pre class="programlisting">struct task : coroutine
-{
-  ...
-  void operator()()
-  {
-    reenter (this)
-    {
-      while (... not finished ...)
-      {

-<p>
-        <span class="bold"><strong>yield break ;</strong></span>
-      </p>
-<p>
-        The final form of <code class="computeroutput">yield</code> is used to explicitly terminate the
-        coroutine. This form is comprised of two steps:
-      </p>
-<div class="itemizedlist"><ul class="itemizedlist" type="disc">
-<li class="listitem">
-            <code class="computeroutput">yield</code> sets the coroutine state to indicate termination.
-          </li>
-<li class="listitem">
-            Control is transferred to the end of the coroutine body.
-          </li>
-</ul></div>
-<p>
-        Once terminated, calls to <code class="computeroutput">is_complete()</code> return true and the
-        coroutine cannot be reentered.
-      </p>
-<p>
-        Note that a coroutine may also be implicitly terminated if the coroutine
-        body is exited without a yield, e.g. by return, throw or by running to the
-        end of the body.
-      </p>
-<p>
-        <span class="bold"><strong>fork <span class="emphasis"><em>statement</em></span></strong></span>
-      </p>
-<p>
-        The <code class="computeroutput">fork</code> pseudo-keyword is used when "forking" a coroutine,
-        i.e. splitting it into two (or more) copies. One use of <code class="computeroutput">fork</code>
-        is in a server, where a new coroutine is created to handle each client connection:
-      </p>
-<pre class="programlisting">reenter (this)
-{
-  do
-  {
-    socket_.reset(new tcp::socket(my_context_));
-    yield acceptor-&gt;async_accept(*socket_, *this);
-    fork server(*this)();
-  } while (is_parent());
-  ... client-specific handling follows ...
-}
-</pre>
-<p>
-        The logical steps involved in a <code class="computeroutput">fork</code> are:
-      </p>
-<div class="itemizedlist"><ul class="itemizedlist" type="disc">
-<li class="listitem">
-            <code class="computeroutput">fork</code> saves the current state of the coroutine.
-          </li>
-<li class="listitem">
-            The statement creates a copy of the coroutine and either executes it
-            immediately or schedules it for later execution.
-          </li>
-<li class="listitem">
-            The resume point is defined immediately following the semicolon.
-          </li>
-<li class="listitem">
-            For the "parent", control immediately continues from the next
-            line.
-          </li>
-</ul></div>
-<p>
-        The functions <code class="computeroutput">is_parent()</code> and <code class="computeroutput">is_child()</code> can be
-        used to differentiate between parent and child. You would use these functions
-        to alter subsequent control flow.
-      </p>
-<p>
-        Note that <code class="computeroutput">fork</code> doesn't do the actual forking by itself. It is
-        the application's responsibility to create a clone of the coroutine and call
-        it. The clone can be called immediately, as above, or scheduled for delayed
-        execution using something like <a class="link" href="post.html" title="post"><code class="computeroutput">post</code></a>.

-        implements an extensible, type-safe, polymorphic set of services, indexed
-        by service type.
-      </p>
-<p>
-        Services exist to manage the resources that are shared across an execution
-        context. For example, timers may be implemented in terms of a single timer
-        queue, and this queue would be stored in a service.
-      </p>
-<p>
-        Access to the services of an <a class="link" href="execution_context.html" title="execution_context"><code class="computeroutput">execution_context</code></a>
-        is via three function templates, <code class="computeroutput">use_service()</code>, <code class="computeroutput">add_service()</code>
-        and <code class="computeroutput">has_service()</code>.
-      </p>
-<p>
-        In a call to <code class="computeroutput">use_service&lt;Service&gt;()</code>, the type argument
-        chooses a service, making available all members of the named type. If <code class="computeroutput">Service</code>
-        is not present in an <a class="link" href="execution_context.html" title="execution_context"><code class="computeroutput">execution_context</code></a>,
-        an object of type <code class="computeroutput">Service</code> is created and added to the <a class="link" href="execution_context.html" title="execution_context"><code class="computeroutput">execution_context</code></a>.
-        A C++ program can check if an <a class="link" href="execution_context.html" title="execution_context"><code class="computeroutput">execution_context</code></a>
-        implements a particular service with the function template <code class="computeroutput">has_service&lt;Service&gt;()</code>.
-      </p>
-<p>
-        Service objects may be explicitly added to an <a class="link" href="execution_context.html" title="execution_context"><code class="computeroutput">execution_context</code></a>
-        using the function template <code class="computeroutput">add_service&lt;Service&gt;()</code>. If
-        the <code class="computeroutput">Service</code> is already present, the <a class="link" href="service_already_exists.html" title="service_already_exists"><code class="computeroutput">service_already_exists</code></a>
-        exception is thrown. If the owner of the service is not the same object as
-        the <a class="link" href="execution_context.html" title="execution_context"><code class="computeroutput">execution_context</code></a>
-        parameter, the <a class="link" href="invalid_service_owner.html" title="invalid_service_owner"><code class="computeroutput">invalid_service_owner</code></a>
-        exception is thrown.

-        Once a service reference is obtained from an <a class="link" href="execution_context.html" title="execution_context"><code class="computeroutput">execution_context</code></a>
-        object by calling <code class="computeroutput">use_service()</code>, that reference remains usable
-        as long as the owning <a class="link" href="execution_context.html" title="execution_context"><code class="computeroutput">execution_context</code></a>
-        object exists.
-      </p>
-<p>
-        All service implementations have <a class="link" href="execution_context__service.html" title="execution_context::service"><code class="computeroutput">execution_context::service</code></a>
-        as a public base class. Custom services may be implemented by deriving from
-        this class and then added to an <a class="link" href="execution_context.html" title="execution_context"><code class="computeroutput">execution_context</code></a>
-        using the facilities described above.

-        <code class="computeroutput">io_context</code> is an example of such a derived type.
-      </p>
-<p>
-        On destruction, a class that is derived from <a class="link" href="execution_context.html" title="execution_context"><code class="computeroutput">execution_context</code></a>
-        must perform <code class="computeroutput">execution_context::shutdown()</code> followed by <code class="computeroutput">execution_context::destroy()</code>.
-      </p>
-<p>
-        This destruction sequence permits programs to simplify their resource management
-        by using <code class="computeroutput">shared_ptr&lt;&gt;</code>. Where an object's lifetime is tied
-        to the lifetime of a connection (or some other sequence of asynchronous operations),
-        a <code class="computeroutput">shared_ptr</code> to the object would be bound into the handlers
-        for all asynchronous operations associated with it. This works as follows:
-      </p>
-<div class="itemizedlist"><ul class="itemizedlist" type="disc">
-<li class="listitem">
-            When a single connection ends, all associated asynchronous operations
-            complete. The corresponding handler objects are destroyed, and all <code class="computeroutput">shared_ptr</code>
-            references to the objects are destroyed.
-          </li>
-<li class="listitem">
-            To shut down the whole program, the <a class="link" href="io_context.html" title="io_context"><code class="computeroutput">io_context</code></a>
-            function stop() is called to terminate any run() calls as soon as possible.
-            The <a class="link" href="io_context.html" title="io_context"><code class="computeroutput">io_context</code></a>
-            destructor calls <code class="computeroutput">shutdown()</code> and <code class="computeroutput">destroy()</code> to
-            destroy all pending handlers, causing all <code class="computeroutput">shared_ptr</code> references
-            to all connection objects to be destroyed.
-          </li>

-        Note that multiple registration only works for signals that are registered

-        The <code class="computeroutput">basic_streambuf</code> class is derived from <code class="computeroutput">std::streambuf</code>
-        to associate the streambuf's input and output sequences with one or more
-        character arrays. These character arrays are internal to the <code class="computeroutput">basic_streambuf</code>
-        object, but direct access to the array elements is provided to permit them
-        to be used efficiently with I/O operations. Characters written to the output
-        sequence of a <code class="computeroutput">basic_streambuf</code> object are appended to the input
-        sequence of the same object.
-      </p>

-        The <code class="computeroutput">basic_streambuf</code> class's public interface is intended to

-<li class="listitem">
-            A single contiguous character array, which is reallocated as necessary

-            the implementation approach currently used in Asio.
-          </li>
-<li class="listitem">
-            A sequence of one or more character arrays, where each array is of the
-            same size. Additional character array objects are appended to the sequence

-          </li>
-<li class="listitem">
-            A sequence of one or more character arrays of varying sizes. Additional

-      </p>
-<pre class="programlisting">size() &lt;= max_size()

-          The system executor represents an execution context where functions are

-          is established, the system executor will schedule the function to run on
-          an unspecified system thread pool. When either blocking.possibly or blocking.always
-          is established, the executor invokes the function immediately.

-        The <code class="computeroutput">use_awaitable_t</code> class, with its value <code class="computeroutput">use_awaitable</code>,
-        is used to represent the currently executing coroutine. This completion token
-        may be passed as a handler to an asynchronous operation. For example:
-      </p>
-<pre class="programlisting">awaitable&lt;void&gt; my_coroutine()
-{
-  std::size_t n = co_await my_socket.async_read_some(buffer, use_awaitable);
-  ...
-}
-</pre>
-<p>
-        When used with co_await, the initiating function (<code class="computeroutput">async_read_some</code>
-        in the above example) suspends the current coroutine. The coroutine is resumed
-        when the asynchronous operation completes, and the result of the operation
-        is returned.

-          The <code class="computeroutput">use_awaitable_t</code> class, with its value <code class="computeroutput">use_awaitable</code>,
-          is used to represent the currently executing coroutine. This completion

-<p>
-        This tutorial program shows how to use asio to implement a client application
-        with TCP.
-      </p>
-<p>
-        We start by including the necessary header files.
-      </p>
-<pre class="programlisting">#include &lt;iostream&gt;
-#include &lt;boost/array.hpp&gt;
-#include &lt;asio.hpp&gt;
-</pre>
-<p>
-        The purpose of this application is to access a daytime service, so we need
-        the user to specify the server.
-      </p>
-<pre class="programlisting">using asio::ip::tcp;
-
-int main(int argc, char* argv[])
-{
-  try
-  {
-    if (argc != 2)
-    {
-      std::cerr &lt;&lt; "Usage: client &lt;host&gt;" &lt;&lt; std::endl;
-      return 1;
-    }
-</pre>
-<p>
-        All programs that use asio need to have at least one I/O execution context,
-        such as an <a class="link" href="../reference/io_context.html" title="io_context">io_context</a> object.
-      </p>
-<pre class="programlisting">    asio::io_context io_context;
-</pre>
-<p>
-        We need to turn the server name that was specified as a parameter to the
-        application, into a TCP endpoint. To do this we use an <a class="link" href="../reference/ip__tcp/resolver.html" title="ip::tcp::resolver">ip::tcp::resolver</a>
-        object.
-      </p>
-<pre class="programlisting">    tcp::resolver resolver(io_context);
-</pre>
-<p>
-        A resolver takes a host name and service name and turns them into a list
-        of endpoints. We perform a resolve call using the name of the server, specified
-        in <code class="computeroutput">argv[1]</code>, and the name of the service, in this case <code class="computeroutput">"daytime"</code>.
-      </p>
-<p>
-        The list of endpoints is returned using an object of type <a class="link" href="../reference/ip__basic_resolver/results_type.html" title="ip::basic_resolver::results_type">ip::tcp::resolver::results_type</a>.
-        This object is a range, with begin() and end() member functions that may
-        be used for iterating over the results.
-      </p>
-<pre class="programlisting">    tcp::resolver::results_type endpoints =
-      resolver.resolve(argv[1], "daytime");
-</pre>
-<p>
-        Now we create and connect the socket. The list of endpoints obtained above
-        may contain both IPv4 and IPv6 endpoints, so we need to try each of them
-        until we find one that works. This keeps the client program independent of
-        a specific IP version. The asio::connect() function does this for us automatically.
-      </p>
-<pre class="programlisting">    tcp::socket socket(io_context);
-    asio::connect(socket, endpoints);
-</pre>
-<p>
-        The connection is open. All we need to do now is read the response from the
-        daytime service.
-      </p>
-<p>
-        We use a <code class="computeroutput">boost::array</code> to hold the received data. The asio::buffer()
-        function automatically determines the size of the array to help prevent buffer
-        overruns. Instead of a <code class="computeroutput">boost::array</code>, we could have used a <code class="computeroutput">char
-        []</code> or <code class="computeroutput">std::vector</code>.
-      </p>
-<pre class="programlisting">    for (;;)
-    {
-      boost::array&lt;char, 128&gt; buf;
-      asio::error_code error;
-
-      size_t len = socket.read_some(asio::buffer(buf), error);
-</pre>
-<p>
-        When the server closes the connection, the <a class="link" href="../reference/basic_stream_socket/read_some.html" title="basic_stream_socket::read_some">ip::tcp::socket::read_some()</a>
-        function will exit with the asio::error::eof error, which is how we know
-        to exit the loop.
-      </p>
-<pre class="programlisting">      if (error == asio::error::eof)

-<p>
-        This tutorial program shows how to use asio to implement a client application
-        with UDP.
-      </p>
-<pre class="programlisting">#include &lt;iostream&gt;
-#include &lt;boost/array.hpp&gt;
-#include &lt;asio.hpp&gt;
-
-using asio::ip::udp;
-</pre>
-<p>
-        The start of the application is essentially the same as for the TCP daytime
-        client.
-      </p>
-<pre class="programlisting">int main(int argc, char* argv[])
-{
-  try
-  {
-    if (argc != 2)
-    {
-      std::cerr &lt;&lt; "Usage: client &lt;host&gt;" &lt;&lt; std::endl;
-      return 1;
-    }
-
-    asio::io_context io_context;
-</pre>
-<p>
-        We use an <a class="link" href="../reference/ip__udp/resolver.html" title="ip::udp::resolver">ip::udp::resolver</a>
-        object to find the correct remote endpoint to use based on the host and service
-        names. The query is restricted to return only IPv4 endpoints by the <a class="link" href="../reference/ip__udp/v4.html" title="ip::udp::v4">ip::udp::v4()</a> argument.
-      </p>
-<pre class="programlisting">    udp::resolver resolver(io_context);
-    udp::endpoint receiver_endpoint =
-      *resolver.resolve(udp::v4(), argv[1], "daytime").begin();
-</pre>
-<p>
-        The <a class="link" href="../reference/ip__basic_resolver/resolve.html" title="ip::basic_resolver::resolve">ip::udp::resolver::resolve()</a>
-        function is guaranteed to return at least one endpoint in the list if it
-        does not fail. This means it is safe to dereference the return value directly.
-      </p>
-<p>
-        Since UDP is datagram-oriented, we will not be using a stream socket. Create
-        an <a class="link" href="../reference/ip__udp/socket.html" title="ip::udp::socket">ip::udp::socket</a> and
-        initiate contact with the remote endpoint.
-      </p>
-<pre class="programlisting">    udp::socket socket(io_context);
-    socket.open(udp::v4());
-
-    boost::array&lt;char, 1&gt; send_buf  = {{ 0 }};
-    socket.send_to(asio::buffer(send_buf), receiver_endpoint);
-</pre>
-<p>
-        Now we need to be ready to accept whatever the server sends back to us. The
-        endpoint on our side that receives the server's response will be initialised
-        by <a class="link" href="../reference/basic_datagram_socket/receive_from.html" title="basic_datagram_socket::receive_from">ip::udp::socket::receive_from()</a>.
-      </p>

-        asio::buffer(recv_buf), sender_endpoint);
-
-    std::cout.write(recv_buf.data(), len);
-  }
-</pre>
-<p>
-        Finally, handle any exceptions that may have been thrown.
-      </p>

-<p>
-        This tutorial program introduces asio by showing how to perform a blocking
-        wait on a timer.
-      </p>
-<p>
-        We start by including the necessary header files.
-      </p>
-<p>
-        All of the asio classes can be used by simply including the <code class="computeroutput">"asio.hpp"</code>
-        header file.
-      </p>
-<pre class="programlisting">#include &lt;iostream&gt;
-#include &lt;asio.hpp&gt;
-</pre>
-<p>
-        All programs that use asio need to have at least one I/O execution context,
-        such as an <a class="link" href="../reference/io_context.html" title="io_context">io_context</a> or
-        <a class="link" href="../reference/thread_pool.html" title="thread_pool">thread_pool</a> object. An
-        I/O execution context provides access to I/O functionality. We declare an
-        object of type <a class="link" href="../reference/io_context.html" title="io_context">io_context</a>
-        first thing in the main function.
-      </p>
-<pre class="programlisting">int main()
-{
-  asio::io_context io;
-</pre>
-<p>
-        Next we declare an object of type asio::steady_timer. The core asio classes
-        that provide I/O functionality (or as in this case timer functionality) always
-        take a reference to an io_context as their first constructor argument. The
-        second argument to the constructor sets the timer to expire 5 seconds from
-        now.
-      </p>
-<pre class="programlisting">  asio::steady_timer t(io, asio::chrono::seconds(5));
-</pre>
-<p>
-        In this simple example we perform a blocking wait on the timer. That is,
-        the call to <a class="link" href="../reference/basic_waitable_timer/wait.html" title="basic_waitable_timer::wait">steady_timer::wait()</a>
-        will not return until the timer has expired, 5 seconds after it was created
-        (i.e. not from when the wait starts).
-      </p>
-<p>
-        A timer is always in one of two states: "expired" or "not
-        expired". If the <a class="link" href="../reference/basic_waitable_timer/wait.html" title="basic_waitable_timer::wait">steady_timer::wait()</a>
-        function is called on an expired timer, it will return immediately.
-      </p>
-<pre class="programlisting">  t.wait();
-</pre>
-<p>
-        Finally we print the obligatory <code class="computeroutput">"Hello, world!"</code> message
-        to show when the timer has expired.
-      </p>
-<pre class="programlisting">  std::cout &lt;&lt; "Hello, world!" &lt;&lt; std::endl;
-
-  return 0;
-}

-<p>
-        This tutorial program demonstrates how to use asio's asynchronous callback
-        functionality by modifying the program from tutorial Timer.1 to perform an
-        asynchronous wait on the timer.
-      </p>
-<pre class="programlisting">#include &lt;iostream&gt;
-#include &lt;asio.hpp&gt;
-</pre>
-<p>
-        Using asio's asynchronous functionality means having a callback function
-        that will be called when an asynchronous operation completes. In this program
-        we define a function called <code class="computeroutput">print</code> to be called when the asynchronous
-        wait finishes.
-      </p>
-<pre class="programlisting">void print(const asio::error_code&amp; /*e*/)
-{
-  std::cout &lt;&lt; "Hello, world!" &lt;&lt; std::endl;
-}
-
-int main()
-{
-  asio::io_context io;
-
-  asio::steady_timer t(io, asio::chrono::seconds(5));
-</pre>
-<p>
-        Next, instead of doing a blocking wait as in tutorial Timer.1, we call the
-        <a class="link" href="../reference/basic_waitable_timer/async_wait.html" title="basic_waitable_timer::async_wait">steady_timer::async_wait()</a>
-        function to perform an asynchronous wait. When calling this function we pass
-        the <code class="computeroutput">print</code> callback handler that was defined above.
-      </p>
-<pre class="programlisting">  t.async_wait(&amp;print);
-</pre>
-<p>
-        Finally, we must call the <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>
-        member function on the io_context object.
-      </p>
-<p>
-        The asio library provides a guarantee that callback handlers will only be
-        called from threads that are currently calling <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>.
-        Therefore unless the <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>
-        function is called the callback for the asynchronous wait completion will
-        never be invoked.
-      </p>
-<p>
-        The <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>
-        function will also continue to run while there is still "work"
-        to do. In this example, the work is the asynchronous wait on the timer, so
-        the call will not return until the timer has expired and the callback has
-        completed.
-      </p>
-<p>
-        It is important to remember to give the io_context some work to do before
-        calling <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>.
-        For example, if we had omitted the above call to <a class="link" href="../reference/basic_waitable_timer/async_wait.html" title="basic_waitable_timer::async_wait">steady_timer::async_wait()</a>,
-        the io_context would not have had any work to do, and consequently <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a> would have
-        returned immediately.
-      </p>
-<pre class="programlisting">  io.run();
-
-  return 0;

-        In this tutorial we will modify the program from tutorial Timer.2 so that
-        the timer fires once a second. This will show how to pass additional parameters
-        to your handler function.
-      </p>
-<pre class="programlisting">#include &lt;iostream&gt;
-#include &lt;asio.hpp&gt;
-#include &lt;boost/bind/bind.hpp&gt;
-</pre>
-<p>
-        To implement a repeating timer using asio you need to change the timer's
-        expiry time in your callback function, and to then start a new asynchronous
-        wait. Obviously this means that the callback function will need to be able
-        to access the timer object. To this end we add two new parameters to the
-        <code class="computeroutput">print</code> function:
-      </p>
-<div class="itemizedlist"><ul class="itemizedlist" type="disc">
-<li class="listitem">
-            A pointer to a timer object.
-          </li>
-<li class="listitem">
-            A counter so that we can stop the program when the timer fires for the
-            sixth time.
-          </li>
-</ul></div>
-<pre class="programlisting">void print(const asio::error_code&amp; /*e*/,
-    asio::steady_timer* t, int* count)
-{
-</pre>
-<p>
-        As mentioned above, this tutorial program uses a counter to stop running
-        when the timer fires for the sixth time. However you will observe that there
-        is no explicit call to ask the io_context to stop. Recall that in tutorial
-        Timer.2 we learnt that the <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>
-        function completes when there is no more "work" to do. By not starting
-        a new asynchronous wait on the timer when <code class="computeroutput">count</code> reaches 5, the
-        io_context will run out of work and stop running.
-      </p>
-<pre class="programlisting">  if (*count &lt; 5)
-  {
-    std::cout &lt;&lt; *count &lt;&lt; std::endl;
-    ++(*count);
-</pre>
-<p>
-        Next we move the expiry time for the timer along by one second from the previous
-        expiry time. By calculating the new expiry time relative to the old, we can
-        ensure that the timer does not drift away from the whole-second mark due
-        to any delays in processing the handler.
-      </p>
-<pre class="programlisting">    t-&gt;expires_at(t-&gt;expiry() + asio::chrono::seconds(1));
-</pre>
-<p>
-        Then we start a new asynchronous wait on the timer. As you can see, the
-        <a class="link" href="boost_bind.html" title="boost::bind">boost::bind</a> function is used
-        to associate the extra parameters with your callback handler. The <a class="link" href="../reference/basic_waitable_timer/async_wait.html" title="basic_waitable_timer::async_wait">steady_timer::async_wait()</a>
-        function expects a handler function (or function object) with the signature
-        <code class="computeroutput">void(const asio::error_code&amp;)</code>. Binding the additional parameters
-        converts your <code class="computeroutput">print</code> function into a function object that matches
-        the signature correctly.
-      </p>
-<p>
-        See the <a href="http://www.boost.org/libs/bind/bind.html" target="_top">Boost.Bind
-        documentation</a> for more information on how to use <a class="link" href="boost_bind.html" title="boost::bind">boost::bind</a>
-        .
-      </p>
-<p>
-        In this example, the asio::placeholders::error argument to <a class="link" href="boost_bind.html" title="boost::bind">boost::bind</a>
-        is a named placeholder for the error object passed to the handler. When initiating
-        the asynchronous operation, and if using <a class="link" href="boost_bind.html" title="boost::bind">boost::bind</a>
-        , you must specify only the arguments that match the handler's parameter
-        list. In tutorial Timer.4 you will see that this placeholder may be elided
-        if the parameter is not needed by the callback handler.
-      </p>
-<pre class="programlisting">    t-&gt;async_wait(boost::bind(print,
-          asio::placeholders::error, t, count));
-  }
-}
-
-int main()
-{
-  asio::io_context io;
-</pre>
-<p>
-        A new <code class="computeroutput">count</code> variable is added so that we can stop the program
-        when the timer fires for the sixth time.
-      </p>
-<pre class="programlisting">  int count = 0;
-  asio::steady_timer t(io, asio::chrono::seconds(1));
-</pre>
-<p>
-        As in Step 4, when making the call to <a class="link" href="../reference/basic_waitable_timer/async_wait.html" title="basic_waitable_timer::async_wait">steady_timer::async_wait()</a>
-        from <code class="computeroutput">main</code> we bind the additional parameters needed for the

-<pre class="programlisting">  t.async_wait(boost::bind(print,
-        asio::placeholders::error, &amp;t, &amp;count));
-
-  io.run();
-</pre>
-<p>
-        Finally, just to prove that the <code class="computeroutput">count</code> variable was being used
-        in the <code class="computeroutput">print</code> handler function, we will print out its new value.

-      as a handler</a>
-</h3></div></div></div>
-<p>
-        In this tutorial we will see how to use a class member function as a callback
-        handler. The program should execute identically to the tutorial program from
-        tutorial Timer.3.
-      </p>
-<pre class="programlisting">#include &lt;iostream&gt;
-#include &lt;asio.hpp&gt;
-#include &lt;boost/bind/bind.hpp&gt;
-</pre>
-<p>
-        Instead of defining a free function <code class="computeroutput">print</code> as the callback handler,
-        as we did in the earlier tutorial programs, we now define a class called
-        <code class="computeroutput">printer</code>.
-      </p>
-<pre class="programlisting">class printer
-{
-public:
-</pre>
-<p>
-        The constructor of this class will take a reference to the io_context object
-        and use it when initialising the <code class="computeroutput">timer_</code> member. The counter
-        used to shut down the program is now also a member of the class.
-      </p>
-<pre class="programlisting">  printer(asio::io_context&amp; io)
-    : timer_(io, asio::chrono::seconds(1)),
-      count_(0)
-  {
-</pre>
-<p>
-        The <a class="link" href="boost_bind.html" title="boost::bind">boost::bind</a> function
-        works just as well with class member functions as with free functions. Since
-        all non-static class member functions have an implicit <code class="computeroutput">this</code>
-        parameter, we need to bind <code class="computeroutput">this</code> to the function. As in tutorial
-        Timer.3, <a class="link" href="boost_bind.html" title="boost::bind">boost::bind</a> converts
-        our callback handler (now a member function) into a function object that
-        can be invoked as though it has the signature <code class="computeroutput">void(const asio::error_code&amp;)</code>.
-      </p>
-<p>
-        You will note that the asio::placeholders::error placeholder is not specified
-        here, as the <code class="computeroutput">print</code> member function does not accept an error
-        object as a parameter.
-      </p>
-<pre class="programlisting">    timer_.async_wait(boost::bind(&amp;printer::print, this));
-  }
-</pre>
-<p>
-        In the class destructor we will print out the final value of the counter.
-      </p>
-<pre class="programlisting">  ~printer()
-  {
-    std::cout &lt;&lt; "Final count is " &lt;&lt; count_ &lt;&lt; std::endl;
-  }
-</pre>
-<p>
-        The <code class="computeroutput">print</code> member function is very similar to the <code class="computeroutput">print</code>
-        function from tutorial Timer.3, except that it now operates on the class
-        data members instead of having the timer and counter passed in as parameters.
-      </p>
-<pre class="programlisting">  void print()
-  {
-    if (count_ &lt; 5)
-    {
-      std::cout &lt;&lt; count_ &lt;&lt; std::endl;
-      ++count_;
-
-      timer_.expires_at(timer_.expiry() + asio::chrono::seconds(1));
-      timer_.async_wait(boost::bind(&amp;printer::print, this));
-    }
-  }
-
-private:
-  asio::steady_timer timer_;
-  int count_;
-};
-</pre>
-<p>
-        The <code class="computeroutput">main</code> function is much simpler than before, as it now declares
-        a local <code class="computeroutput">printer</code> object before running the io_context as normal.
-      </p>

-      in multithreaded programs</a>
-</h3></div></div></div>
-<p>
-        This tutorial demonstrates the use of the <a class="link" href="../reference/strand.html" title="strand">strand</a>
-        class template to synchronise callback handlers in a multithreaded program.
-      </p>
-<p>
-        The previous four tutorials avoided the issue of handler synchronisation
-        by calling the <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>
-        function from one thread only. As you already know, the asio library provides
-        a guarantee that callback handlers will only be called from threads that
-        are currently calling <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>.
-        Consequently, calling <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>
-        from only one thread ensures that callback handlers cannot run concurrently.
-      </p>
-<p>
-        The single threaded approach is usually the best place to start when developing
-        applications using asio. The downside is the limitations it places on programs,
-        particularly servers, including:
-      </p>
-<div class="itemizedlist"><ul class="itemizedlist" type="disc">
-<li class="listitem">
-            Poor responsiveness when handlers can take a long time to complete.
-          </li>
-<li class="listitem">
-            An inability to scale on multiprocessor systems.
-          </li>
-</ul></div>
-<p>
-        If you find yourself running into these limitations, an alternative approach
-        is to have a pool of threads calling <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>.
-        However, as this allows handlers to execute concurrently, we need a method
-        of synchronisation when handlers might be accessing a shared, thread-unsafe
-        resource.
-      </p>
-<pre class="programlisting">#include &lt;iostream&gt;
-#include &lt;asio.hpp&gt;
-#include &lt;boost/bind/bind.hpp&gt;
-</pre>
-<p>
-        We start by defining a class called <code class="computeroutput">printer</code>, similar to the
-        class in the previous tutorial. This class will extend the previous tutorial
-        by running two timers in parallel.
-      </p>
-<pre class="programlisting">class printer
-{
-public:
-</pre>
-<p>
-        In addition to initialising a pair of asio::steady_timer members, the constructor
-        initialises the <code class="computeroutput">strand_</code> member, an object of type asio::strand&lt;asio::io_context::executor_type&gt;.
-      </p>
-<p>
-        The <a class="link" href="../reference/strand.html" title="strand">strand</a> class template is
-        an executor adapter that guarantees that, for those handlers that are dispatched
-        through it, an executing handler will be allowed to complete before the next
-        one is started. This is guaranteed irrespective of the number of threads
-        that are calling <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>.
-        Of course, the handlers may still execute concurrently with other handlers
-        that were not dispatched through an <a class="link" href="../reference/strand.html" title="strand">strand</a>,
-        or were dispatched through a different <a class="link" href="../reference/strand.html" title="strand">strand</a>
-        object.
-      </p>
-<pre class="programlisting">  printer(asio::io_context&amp; io)
-    : strand_(asio::make_strand(io)),
-      timer1_(io, asio::chrono::seconds(1)),
-      timer2_(io, asio::chrono::seconds(1)),
-      count_(0)
-  {
-</pre>
-<p>
-        When initiating the asynchronous operations, each callback handler is "bound"
-        to an asio::strand&lt;asio::io_context::executor_type&gt; object. The asio::bind_executor()
-        function returns a new handler that automatically dispatches its contained
-        handler through the <a class="link" href="../reference/strand.html" title="strand">strand</a> object.
-        By binding the handlers to the same <a class="link" href="../reference/strand.html" title="strand">strand</a>,
-        we are ensuring that they cannot execute concurrently.
-      </p>
-<pre class="programlisting">    timer1_.async_wait(asio::bind_executor(strand_,
-          boost::bind(&amp;printer::print1, this)));
-
-    timer2_.async_wait(asio::bind_executor(strand_,
-          boost::bind(&amp;printer::print2, this)));
-  }
-
-  ~printer()
-  {
-    std::cout &lt;&lt; "Final count is " &lt;&lt; count_ &lt;&lt; std::endl;
-  }
-</pre>
-<p>
-        In a multithreaded program, the handlers for asynchronous operations should
-        be synchronised if they access shared resources. In this tutorial, the shared
-        resources used by the handlers (<code class="computeroutput">print1</code> and <code class="computeroutput">print2</code>)
-        are <code class="computeroutput">std::cout</code> and the <code class="computeroutput">count_</code> data member.
-      </p>
-<pre class="programlisting">  void print1()
-  {
-    if (count_ &lt; 10)

-
-      timer1_.async_wait(asio::bind_executor(strand_,

-    }
-  }
-
-  void print2()

-      std::cout &lt;&lt; "Timer 2: " &lt;&lt; count_ &lt;&lt; std::endl;
-      ++count_;
-
-      timer2_.expires_at(timer2_.expiry() + asio::chrono::seconds(1));
-

-  asio::steady_timer timer2_;

-</pre>
-<p>
-        The <code class="computeroutput">main</code> function now causes <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a>
-        to be called from two threads: the main thread and one additional thread.
-        This is accomplished using an <a class="link" href="../reference/thread.html" title="thread">thread</a>
-        object.
-      </p>
-<p>
-        Just as it would with a call from a single thread, concurrent calls to <a class="link" href="../reference/io_context/run.html" title="io_context::run">io_context::run()</a> will continue
-        to execute while there is "work" left to do. The background thread

-      &lt;asio/impl/src.hpp&gt;</code> to one (and only one) source file in a program,
-      then build the program with <code class="computeroutput">ASIO_SEPARATE_COMPILATION</code> defined
-      in the project/compiler settings. Alternatively, <code class="computeroutput">ASIO_DYN_LINK</code>
-      may be defined to build a separately-compiled Asio as part of a shared library.
-    </p>
-<p>
-      If using Asio's SSL support, you will also need to add <code class="computeroutput">#include &lt;asio/ssl/impl/src.hpp&gt;</code>.

-      If the boost directory (e.g. the directory called <code class="computeroutput">boost_1_34_1</code>)
-      is in the same directory as the asio source kit, then you may configure asio
-      by simply going:
-    </p>
-<pre class="programlisting">./configure
-</pre>
-<p>
-      in the root directory of the asio source kit. Note that configure will always
-      use the most recent boost version it knows about (i.e. 1.34.1) in preference
-      to earlier versions, if there is more than one version present.
-    </p>
-<p>
-      If the boost directory is in some other location, then you need to specify
-      this directory when running configure:
-    </p>
-<pre class="programlisting">./configure --with-boost=<span class="emphasis"><em>path_to_boost</em></span>
-</pre>
-<p>
-      When specifying the boost directory in this way you should ensure that you
-      use an absolute path.
-    </p>
-<p>
-      To build the examples, simply run <code class="computeroutput">make</code> in the root directory of
-      the asio source kit. To also build and run the unit tests, to confirm that
-      asio is working correctly, run <code class="computeroutput">make check</code>.

-/// Provides waitable timer functionality.
-/**
- * The basic_deadline_timer class template provides the ability to perform a
- * blocking or asynchronous wait for a timer to expire.
- *
- * A deadline timer is always in one of two states: "expired" or "not expired".
- * If the wait() or async_wait() function is called on an expired timer, the
- * wait operation will complete immediately.
- *
- * Most applications will use the asio::deadline_timer typedef.
- *
- * @par Thread Safety
- * @e Distinct @e objects: Safe.@n
- * @e Shared @e objects: Unsafe.
- *
- * @par Examples
- * Performing a blocking wait:
- * @code
- * // Construct a timer without setting an expiry time.
- * asio::deadline_timer timer(my_context);
- *
- * // Set an expiry time relative to now.
- * timer.expires_from_now(boost::posix_time::seconds(5));
- *
- * // Wait for the timer to expire.
- * timer.wait();
- * @endcode
- *
- * @par 
- * Performing an asynchronous wait:
- * @code
- * void handler(const asio::error_code& error)
- * {
- *   if (!error)
- *   {
- *     // Timer expired.
- *   }
- * }
- *
- * ...
- *
- * // Construct a timer with an absolute expiry time.
- * asio::deadline_timer timer(my_context,
- *     boost::posix_time::time_from_string("2005-12-07 23:59:59.000"));
- *
- * // Start an asynchronous wait.
- * timer.async_wait(handler);
- * @endcode
- *
- * @par Changing an active deadline_timer's expiry time
- *
- * Changing the expiry time of a timer while there are pending asynchronous
- * waits causes those wait operations to be cancelled. To ensure that the action
- * associated with the timer is performed only once, use something like this:
- * used:
- *
- * @code
- * void on_some_event()
- * {
- *   if (my_timer.expires_from_now(seconds(5)) > 0)
- *   {
- *     // We managed to cancel the timer. Start new asynchronous wait.
- *     my_timer.async_wait(on_timeout);
- *   }
- *   else
- *   {
- *     // Too late, timer has already expired!
- *   }
- * }
- *
- * void on_timeout(const asio::error_code& e)
- * {
- *   if (e != asio::error::operation_aborted)
- *   {
- *     // Timer was not cancelled, take necessary action.
- *   }
- * }
- * @endcode
- *
- * @li The asio::basic_deadline_timer::expires_from_now() function
- * cancels any pending asynchronous waits, and returns the number of
- * asynchronous waits that were cancelled. If it returns 0 then you were too
- * late and the wait handler has already been executed, or will soon be
- * executed. If it returns 1 then the wait handler was successfully cancelled.
- *
- * @li If a wait handler is cancelled, the asio::error_code passed to
- * it contains the value asio::error::operation_aborted.

-/// Provides signal functionality.
-/**
- * The basic_signal_set class provides the ability to perform an asynchronous
- * wait for one or more signals to occur.
- *
- * @par Thread Safety
- * @e Distinct @e objects: Safe.@n
- * @e Shared @e objects: Unsafe.
- *
- * @par Example
- * Performing an asynchronous wait:
- * @code
- * void handler(
- *     const asio::error_code& error,
- *     int signal_number)
- * {
- *   if (!error)
- *   {
- *     // A signal occurred.
- *   }
- * }
- *
- * ...
- *
- * // Construct a signal set registered for process termination.
- * asio::signal_set signals(my_context, SIGINT, SIGTERM);
- *
- * // Start an asynchronous wait for one of the signals to occur.
- * signals.async_wait(handler);
- * @endcode
- *
- * @par Queueing of signal notifications
- *
- * If a signal is registered with a signal_set, and the signal occurs when
- * there are no waiting handlers, then the signal notification is queued. The
- * next async_wait operation on that signal_set will dequeue the notification.
- * If multiple notifications are queued, subsequent async_wait operations
- * dequeue them one at a time. Signal notifications are dequeued in order of
- * ascending signal number.
- *
- * If a signal number is removed from a signal_set (using the @c remove or @c
- * erase member functions) then any queued notifications for that signal are
- * discarded.
- *
- * @par Multiple registration of signals
- *
- * The same signal number may be registered with different signal_set objects.
- * When the signal occurs, one handler is called for each signal_set object.
- *
- * Note that multiple registration only works for signals that are registered
- * using Asio. The application must not also register a signal handler using
- * functions such as @c signal() or @c sigaction().
- *
- * @par Signal masking on POSIX platforms
- *
- * POSIX allows signals to be blocked using functions such as @c sigprocmask()
- * and @c pthread_sigmask(). For signals to be delivered, programs must ensure
- * that any signals registered using signal_set objects are unblocked in at
- * least one thread.

-/// Automatically resizable buffer class based on std::streambuf.
-/**
- * The @c basic_streambuf class is derived from @c std::streambuf to associate
- * the streambuf's input and output sequences with one or more character
- * arrays. These character arrays are internal to the @c basic_streambuf
- * object, but direct access to the array elements is provided to permit them
- * to be used efficiently with I/O operations. Characters written to the output
- * sequence of a @c basic_streambuf object are appended to the input sequence
- * of the same object.
- *
- * The @c basic_streambuf class's public interface is intended to permit the
- * following implementation strategies:
- *
- * @li A single contiguous character array, which is reallocated as necessary
- * to accommodate changes in the size of the character sequence. This is the
- * implementation approach currently used in Asio.
- *
- * @li A sequence of one or more character arrays, where each array is of the
- * same size. Additional character array objects are appended to the sequence
- * to accommodate changes in the size of the character sequence.
- *
- * @li A sequence of one or more character arrays of varying sizes. Additional
- * character array objects are appended to the sequence to accommodate changes
- * in the size of the character sequence.
- *
- * The constructor for basic_streambuf accepts a @c size_t argument specifying
- * the maximum of the sum of the sizes of the input sequence and output
- * sequence. During the lifetime of the @c basic_streambuf object, the following
- * invariant holds:
- * @code size() <= max_size()@endcode
- * Any member function that would, if successful, cause the invariant to be
- * violated shall throw an exception of class @c std::length_error.
- *
- * The constructor for @c basic_streambuf takes an Allocator argument. A copy
- * of this argument is used for any memory allocation performed, by the
- * constructor and by all member functions, during the lifetime of each @c
- * basic_streambuf object.
- *
- * @par Examples
- * Writing directly from an streambuf to a socket:
- * @code
- * asio::streambuf b;
- * std::ostream os(&b);
- * os << "Hello, World!\n";
- *
- * // try sending some data in input sequence
- * size_t n = sock.send(b.data());
- *
- * b.consume(n); // sent data is removed from input sequence
- * @endcode
- *
- * Reading from a socket directly into a streambuf:
- * @code
- * asio::streambuf b;
- *
- * // reserve 512 bytes in output sequence
- * asio::streambuf::mutable_buffers_type bufs = b.prepare(512);
- *
- * size_t n = sock.receive(bufs);
- *
- * // received data is "committed" from output sequence to input sequence
- * b.commit(n);
- *
- * std::istream is(&b);
- * std::string s;
- * is >> s;
- * @endcode

-/// Provides waitable timer functionality.
-/**
- * The basic_waitable_timer class template provides the ability to perform a
- * blocking or asynchronous wait for a timer to expire.
- *
- * A waitable timer is always in one of two states: "expired" or "not expired".
- * If the wait() or async_wait() function is called on an expired timer, the
- * wait operation will complete immediately.
- *
- * Most applications will use one of the asio::steady_timer,
- * asio::system_timer or asio::high_resolution_timer typedefs.
- *
- * @note This waitable timer functionality is for use with the C++11 standard
- * library's @c &lt;chrono&gt; facility, or with the Boost.Chrono library.
- *
- * @par Thread Safety
- * @e Distinct @e objects: Safe.@n
- * @e Shared @e objects: Unsafe.
- *
- * @par Examples
- * Performing a blocking wait (C++11):
- * @code
- * // Construct a timer without setting an expiry time.
- * asio::steady_timer timer(my_context);
- *
- * // Set an expiry time relative to now.
- * timer.expires_after(std::chrono::seconds(5));
- *
- * // Wait for the timer to expire.
- * timer.wait();
- * @endcode
- *
- * @par 
- * Performing an asynchronous wait (C++11):
- * @code
- * void handler(const asio::error_code& error)
- * {
- *   if (!error)
- *   {
- *     // Timer expired.
- *   }
- * }
- *
- * ...
- *
- * // Construct a timer with an absolute expiry time.
- * asio::steady_timer timer(my_context,
- *     std::chrono::steady_clock::now() + std::chrono::seconds(60));
- *
- * // Start an asynchronous wait.
- * timer.async_wait(handler);
- * @endcode
- *
- * @par Changing an active waitable timer's expiry time
- *
- * Changing the expiry time of a timer while there are pending asynchronous
- * waits causes those wait operations to be cancelled. To ensure that the action
- * associated with the timer is performed only once, use something like this:
- * used:
- *
- * @code
- * void on_some_event()
- * {
- *   if (my_timer.expires_after(seconds(5)) > 0)
- *   {
- *     // We managed to cancel the timer. Start new asynchronous wait.
- *     my_timer.async_wait(on_timeout);
- *   }
- *   else
- *   {
- *     // Too late, timer has already expired!
- *   }
- * }
- *
- * void on_timeout(const asio::error_code& e)
- * {
- *   if (e != asio::error::operation_aborted)
- *   {
- *     // Timer was not cancelled, take necessary action.
- *   }
- * }
- * @endcode
- *
- * @li The asio::basic_waitable_timer::expires_after() function
- * cancels any pending asynchronous waits, and returns the number of
- * asynchronous waits that were cancelled. If it returns 0 then you were too
- * late and the wait handler has already been executed, or will soon be
- * executed. If it returns 1 then the wait handler was successfully cancelled.
- *
- * @li If a wait handler is cancelled, the asio::error_code passed to
- * it contains the value asio::error::operation_aborted.

-/** @defgroup buffer asio::buffer
- *
- * @brief The asio::buffer function is used to create a buffer object to
- * represent raw memory, an array of POD elements, a vector of POD elements,
- * or a std::string.
- *
- * A buffer object represents a contiguous region of memory as a 2-tuple
- * consisting of a pointer and size in bytes. A tuple of the form <tt>{void*,
- * size_t}</tt> specifies a mutable (modifiable) region of memory. Similarly, a
- * tuple of the form <tt>{const void*, size_t}</tt> specifies a const
- * (non-modifiable) region of memory. These two forms correspond to the classes
- * mutable_buffer and const_buffer, respectively. To mirror C++'s conversion
- * rules, a mutable_buffer is implicitly convertible to a const_buffer, and the
- * opposite conversion is not permitted.
- *
- * The simplest use case involves reading or writing a single buffer of a
- * specified size:
- *
- * @code sock.send(asio::buffer(data, size)); @endcode
- *
- * In the above example, the return value of asio::buffer meets the
- * requirements of the ConstBufferSequence concept so that it may be directly
- * passed to the socket's write function. A buffer created for modifiable
- * memory also meets the requirements of the MutableBufferSequence concept.
- *
- * An individual buffer may be created from a builtin array, std::vector,
- * std::array or boost::array of POD elements. This helps prevent buffer
- * overruns by automatically determining the size of the buffer:
- *
- * @code char d1[128];
- * size_t bytes_transferred = sock.receive(asio::buffer(d1));
- *
- * std::vector<char> d2(128);
- * bytes_transferred = sock.receive(asio::buffer(d2));
- *
- * std::array<char, 128> d3;
- * bytes_transferred = sock.receive(asio::buffer(d3));
- *
- * boost::array<char, 128> d4;
- * bytes_transferred = sock.receive(asio::buffer(d4)); @endcode
- *
- * In all three cases above, the buffers created are exactly 128 bytes long.
- * Note that a vector is @e never automatically resized when creating or using
- * a buffer. The buffer size is determined using the vector's <tt>size()</tt>
- * member function, and not its capacity.
- *
- * @par Accessing Buffer Contents
- *
- * The contents of a buffer may be accessed using the @c data() and @c size()
- * member functions:
- *
- * @code asio::mutable_buffer b1 = ...;
- * std::size_t s1 = b1.size();
- * unsigned char* p1 = static_cast<unsigned char*>(b1.data());
- *
- * asio::const_buffer b2 = ...;
- * std::size_t s2 = b2.size();
- * const void* p2 = b2.data(); @endcode
- *
- * The @c data() member function permits violations of type safety, so
- * uses of it in application code should be carefully considered.
- *
- * For convenience, a @ref buffer_size function is provided that works with
- * both buffers and buffer sequences (that is, types meeting the
- * ConstBufferSequence or MutableBufferSequence type requirements). In this
- * case, the function returns the total size of all buffers in the sequence.
- *
- * @par Buffer Copying
- *
- * The @ref buffer_copy function may be used to copy raw bytes between
- * individual buffers and buffer sequences.
-*
- * In particular, when used with the @ref buffer_size function, the @ref
- * buffer_copy function can be used to linearise a sequence of buffers. For
- * example:
- *
- * @code vector<const_buffer> buffers = ...;
- *
- * vector<unsigned char> data(asio::buffer_size(buffers));
- * asio::buffer_copy(asio::buffer(data), buffers); @endcode
- *
- * Note that @ref buffer_copy is implemented in terms of @c memcpy, and
- * consequently it cannot be used to copy between overlapping memory regions.
- *
- * @par Buffer Invalidation
- *
- * A buffer object does not have any ownership of the memory it refers to. It
- * is the responsibility of the application to ensure the memory region remains
- * valid until it is no longer required for an I/O operation. When the memory
- * is no longer available, the buffer is said to have been invalidated.
- *
- * For the asio::buffer overloads that accept an argument of type
- * std::vector, the buffer objects returned are invalidated by any vector
- * operation that also invalidates all references, pointers and iterators
- * referring to the elements in the sequence (C++ Std, 23.2.4)
- *
- * For the asio::buffer overloads that accept an argument of type
- * std::basic_string, the buffer objects returned are invalidated according to
- * the rules defined for invalidation of references, pointers and iterators
- * referring to elements of the sequence (C++ Std, 21.3).
- *
- * @par Buffer Arithmetic
- *
- * Buffer objects may be manipulated using simple arithmetic in a safe way
- * which helps prevent buffer overruns. Consider an array initialised as
- * follows:
- *
- * @code boost::array<char, 6> a = { 'a', 'b', 'c', 'd', 'e' }; @endcode
- *
- * A buffer object @c b1 created using:
- *
- * @code b1 = asio::buffer(a); @endcode
- *
- * represents the entire array, <tt>{ 'a', 'b', 'c', 'd', 'e' }</tt>. An
- * optional second argument to the asio::buffer function may be used to
- * limit the size, in bytes, of the buffer:
- *
- * @code b2 = asio::buffer(a, 3); @endcode
- *
- * such that @c b2 represents the data <tt>{ 'a', 'b', 'c' }</tt>. Even if the
- * size argument exceeds the actual size of the array, the size of the buffer
- * object created will be limited to the array size.
- *
- * An offset may be applied to an existing buffer to create a new one:
- *
- * @code b3 = b1 + 2; @endcode
- *
- * where @c b3 will set to represent <tt>{ 'c', 'd', 'e' }</tt>. If the offset
- * exceeds the size of the existing buffer, the newly created buffer will be
- * empty.
- *
- * Both an offset and size may be specified to create a buffer that corresponds
- * to a specific range of bytes within an existing buffer:
- *
- * @code b4 = asio::buffer(b1 + 1, 3); @endcode
- *
- * so that @c b4 will refer to the bytes <tt>{ 'b', 'c', 'd' }</tt>.
- *
- * @par Buffers and Scatter-Gather I/O
- *
- * To read or write using multiple buffers (i.e. scatter-gather I/O), multiple
- * buffer objects may be assigned into a container that supports the
- * MutableBufferSequence (for read) or ConstBufferSequence (for write) concepts:
- *
- * @code
- * char d1[128];
- * std::vector<char> d2(128);
- * boost::array<char, 128> d3;
- *
- * boost::array<mutable_buffer, 3> bufs1 = {
- *   asio::buffer(d1),
- *   asio::buffer(d2),
- *   asio::buffer(d3) };
- * bytes_transferred = sock.receive(bufs1);
- *
- * std::vector<const_buffer> bufs2;
- * bufs2.push_back(asio::buffer(d1));
- * bufs2.push_back(asio::buffer(d2));
- * bufs2.push_back(asio::buffer(d3));
- * bytes_transferred = sock.send(bufs2); @endcode

- * @brief The asio::buffer_copy function is used to copy bytes from a
- * source buffer (or buffer sequence) to a target buffer (or buffer sequence).
- *
- * The @c buffer_copy function is available in two forms:
- *
- * @li A 2-argument form: @c buffer_copy(target, source)
- *
- * @li A 3-argument form: @c buffer_copy(target, source, max_bytes_to_copy)
- *
- * Both forms return the number of bytes actually copied. The number of bytes
- * copied is the lesser of:
- *
- * @li @c buffer_size(target)
- *
- * @li @c buffer_size(source)
- *
- * @li @c If specified, @c max_bytes_to_copy.
- *
- * This prevents buffer overflow, regardless of the buffer sizes used in the
- * copy operation.
- *
- * Note that @ref buffer_copy is implemented in terms of @c memcpy, and
- * consequently it cannot be used to copy between overlapping memory regions.

-/// Provides support for implementing stackless coroutines.
-/**
- * The @c coroutine class may be used to implement stackless coroutines. The
- * class itself is used to store the current state of the coroutine.
- *
- * Coroutines are copy-constructible and assignable, and the space overhead is
- * a single int. They can be used as a base class:
- *
- * @code class session : coroutine
- * {
- *   ...
- * }; @endcode
- *
- * or as a data member:
- *
- * @code class session
- * {
- *   ...
- *   coroutine coro_;
- * }; @endcode
- *
- * or even bound in as a function argument using lambdas or @c bind(). The
- * important thing is that as the application maintains a copy of the object
- * for as long as the coroutine must be kept alive.
- *
- * @par Pseudo-keywords
- *
- * A coroutine is used in conjunction with certain "pseudo-keywords", which
- * are implemented as macros. These macros are defined by a header file:
- *
- * @code #include <asio/yield.hpp>@endcode
- *
- * and may conversely be undefined as follows:
- *
- * @code #include <asio/unyield.hpp>@endcode
- *
- * <b>reenter</b>
- *
- * The @c reenter macro is used to define the body of a coroutine. It takes a
- * single argument: a pointer or reference to a coroutine object. For example,
- * if the base class is a coroutine object you may write:
- *
- * @code reenter (this)
- * {
- *   ... coroutine body ...
- * } @endcode
- *
- * and if a data member or other variable you can write:
- *
- * @code reenter (coro_)
- * {
- *   ... coroutine body ...
- * } @endcode
- *
- * When @c reenter is executed at runtime, control jumps to the location of the
- * last @c yield or @c fork.
- *
- * The coroutine body may also be a single statement, such as:
- *
- * @code reenter (this) for (;;)
- * {
- *   ...
- * } @endcode
- *
- * @b Limitation: The @c reenter macro is implemented using a switch. This
- * means that you must take care when using local variables within the
- * coroutine body. The local variable is not allowed in a position where
- * reentering the coroutine could bypass the variable definition.
- *
- * <b>yield <em>statement</em></b>
- *
- * This form of the @c yield keyword is often used with asynchronous operations:
- *
- * @code yield socket_->async_read_some(buffer(*buffer_), *this); @endcode
- *
- * This divides into four logical steps:
- *
- * @li @c yield saves the current state of the coroutine.
- * @li The statement initiates the asynchronous operation.
- * @li The resume point is defined immediately following the statement.
- * @li Control is transferred to the end of the coroutine body.
- *
- * When the asynchronous operation completes, the function object is invoked
- * and @c reenter causes control to transfer to the resume point. It is
- * important to remember to carry the coroutine state forward with the
- * asynchronous operation. In the above snippet, the current class is a
- * function object object with a coroutine object as base class or data member.
- *
- * The statement may also be a compound statement, and this permits us to
- * define local variables with limited scope:
- *
- * @code yield
- * {
- *   mutable_buffers_1 b = buffer(*buffer_);
- *   socket_->async_read_some(b, *this);
- * } @endcode
- *
- * <b>yield return <em>expression</em> ;</b>
- *
- * This form of @c yield is often used in generators or coroutine-based parsers.
- * For example, the function object:
- *
- * @code struct interleave : coroutine
- * {
- *   istream& is1;
- *   istream& is2;
- *   char operator()(char c)
- *   {
- *     reenter (this) for (;;)
- *     {
- *       yield return is1.get();
- *       yield return is2.get();
- *     }
- *   }
- * }; @endcode
- *
- * defines a trivial coroutine that interleaves the characters from two input
- * streams.
- *
- * This type of @c yield divides into three logical steps:
- *
- * @li @c yield saves the current state of the coroutine.
- * @li The resume point is defined immediately following the semicolon.
- * @li The value of the expression is returned from the function.
- *
- * <b>yield ;</b>
- *
- * This form of @c yield is equivalent to the following steps:
- *
- * @li @c yield saves the current state of the coroutine.
- * @li The resume point is defined immediately following the semicolon.
- * @li Control is transferred to the end of the coroutine body.
- *
- * This form might be applied when coroutines are used for cooperative
- * threading and scheduling is explicitly managed. For example:
- *
- * @code struct task : coroutine
- * {
- *   ...
- *   void operator()()
- *   {
- *     reenter (this)
- *     {
- *       while (... not finished ...)
- *       {
- *         ... do something ...
- *         yield;
- *         ... do some more ...
- *         yield;
- *       }
- *     }
- *   }
- *   ...
- * };
- * ...
- * task t1, t2;
- * for (;;)
- * {
- *   t1();
- *   t2();
- * } @endcode
- *
- * <b>yield break ;</b>
- *
- * The final form of @c yield is used to explicitly terminate the coroutine.
- * This form is comprised of two steps:
- *
- * @li @c yield sets the coroutine state to indicate termination.
- * @li Control is transferred to the end of the coroutine body.
- *
- * Once terminated, calls to is_complete() return true and the coroutine cannot
- * be reentered.
- *
- * Note that a coroutine may also be implicitly terminated if the coroutine
- * body is exited without a yield, e.g. by return, throw or by running to the
- * end of the body.
- *
- * <b>fork <em>statement</em></b>
- *
- * The @c fork pseudo-keyword is used when "forking" a coroutine, i.e. splitting
- * it into two (or more) copies. One use of @c fork is in a server, where a new
- * coroutine is created to handle each client connection:
- * 
- * @code reenter (this)
- * {
- *   do
- *   {
- *     socket_.reset(new tcp::socket(my_context_));
- *     yield acceptor->async_accept(*socket_, *this);
- *     fork server(*this)();
- *   } while (is_parent());
- *   ... client-specific handling follows ...
- * } @endcode
- * 
- * The logical steps involved in a @c fork are:
- * 
- * @li @c fork saves the current state of the coroutine.
- * @li The statement creates a copy of the coroutine and either executes it
- *     immediately or schedules it for later execution.
- * @li The resume point is defined immediately following the semicolon.
- * @li For the "parent", control immediately continues from the next line.
- *
- * The functions is_parent() and is_child() can be used to differentiate
- * between parent and child. You would use these functions to alter subsequent
- * control flow.
- *
- * Note that @c fork doesn't do the actual forking by itself. It is the
- * application's responsibility to create a clone of the coroutine and call it.
- * The clone can be called immediately, as above, or scheduled for delayed
- * execution using something like asio::post().
- *
- * @par Alternate macro names
- *
- * If preferred, an application can use macro names that follow a more typical
- * naming convention, rather than the pseudo-keywords. These are:
- *
- * @li @c ASIO_CORO_REENTER instead of @c reenter
- * @li @c ASIO_CORO_YIELD instead of @c yield
- * @li @c ASIO_CORO_FORK instead of @c fork

- * <tt>S</tt>, <tt>F</tt>, and <tt>N</tt> is expression-equivalent to:
- *
- * @li <tt>S.bulk_execute(F, N)</tt>, if that expression is valid. If the

- *   object <tt>F</tt> on the executor <tt>S</tt> in bulk with forward progress
- *   guarantee <tt>asio::query(S, execution::bulk_guarantee)</tt>, and
- *   the result of that function does not model <tt>sender<void></tt>, the
- *   program is ill-formed with no diagnostic required.
- *
- * @li Otherwise, <tt>bulk_execute(S, F, N)</tt>, if that expression is valid,

-/// A context for function object execution.
-/**
- * An execution context represents a place where function objects will be
- * executed. An @c io_context is an example of an execution context.
- *
- * @par The execution_context class and services
- *
- * Class execution_context implements an extensible, type-safe, polymorphic set
- * of services, indexed by service type.
- *
- * Services exist to manage the resources that are shared across an execution
- * context. For example, timers may be implemented in terms of a single timer
- * queue, and this queue would be stored in a service.
- *
- * Access to the services of an execution_context is via three function
- * templates, use_service(), add_service() and has_service().
- *
- * In a call to @c use_service<Service>(), the type argument chooses a service,
- * making available all members of the named type. If @c Service is not present
- * in an execution_context, an object of type @c Service is created and added
- * to the execution_context. A C++ program can check if an execution_context
- * implements a particular service with the function template @c
- * has_service<Service>().
- *
- * Service objects may be explicitly added to an execution_context using the
- * function template @c add_service<Service>(). If the @c Service is already
- * present, the service_already_exists exception is thrown. If the owner of the
- * service is not the same object as the execution_context parameter, the
- * invalid_service_owner exception is thrown.
- *
- * Once a service reference is obtained from an execution_context object by
- * calling use_service(), that reference remains usable as long as the owning
- * execution_context object exists.
- *
- * All service implementations have execution_context::service as a public base
- * class. Custom services may be implemented by deriving from this class and
- * then added to an execution_context using the facilities described above.
- *
- * @par The execution_context as a base class
- *
- * Class execution_context may be used only as a base class for concrete
- * execution context types. The @c io_context is an example of such a derived
- * type.
- *
- * On destruction, a class that is derived from execution_context must perform
- * <tt>execution_context::shutdown()</tt> followed by
- * <tt>execution_context::destroy()</tt>.
- *
- * This destruction sequence permits programs to simplify their resource
- * management by using @c shared_ptr<>. Where an object's lifetime is tied to
- * the lifetime of a connection (or some other sequence of asynchronous
- * operations), a @c shared_ptr to the object would be bound into the handlers
- * for all asynchronous operations associated with it. This works as follows:
- *
- * @li When a single connection ends, all associated asynchronous operations
- * complete. The corresponding handler objects are destroyed, and all @c
- * shared_ptr references to the objects are destroyed.
- *
- * @li To shut down the whole program, the io_context function stop() is called
- * to terminate any run() calls as soon as possible. The io_context destructor
- * calls @c shutdown() and @c destroy() to destroy all pending handlers,
- * causing all @c shared_ptr references to all connection objects to be
- * destroyed.

- *
- * @brief (Deprecated: Use the associated_executor trait.) Default invoke
- * function for handlers.
- *
- * Completion handlers for asynchronous operations are invoked by the
- * io_context associated with the corresponding object (e.g. a socket or
- * deadline_timer). Certain guarantees are made on when the handler may be
- * invoked, in particular that a handler can only be invoked from a thread that
- * is currently calling @c run() on the corresponding io_context object.
- * Handlers may subsequently be invoked through other objects (such as
- * io_context::strand objects) that provide additional guarantees.
- *
- * When asynchronous operations are composed from other asynchronous
- * operations, all intermediate handlers should be invoked using the same
- * method as the final handler. This is required to ensure that user-defined
- * objects are not accessed in a way that may violate the guarantees. This
- * hooking function ensures that the invoked method used for the final handler
- * is accessible at each intermediate step.
- *
- * Implement asio_handler_invoke for your own handlers to specify a custom
- * invocation strategy.
- *
- * This default implementation invokes the function object like so:
- * @code function(); @endcode
- * If necessary, the default implementation makes a copy of the function object
- * so that the non-const operator() can be used.
- *
- * @par Example
- * @code
- * class my_handler;
- *
- * template <typename Function>
- * void asio_handler_invoke(Function function, my_handler* context)
- * {
- *   context->strand_.dispatch(function);
- * }

- * associated with the io_context, is being called in another thread.
- *
- * @par Concepts:
- * Dispatcher.
- *
- * @par Synchronous and asynchronous operations
- *
- * Synchronous operations on I/O objects implicitly run the io_context object
- * for an individual operation. The io_context functions run(), run_one(),
- * run_for(), run_until(), poll() or poll_one() must be called for the
- * io_context to perform asynchronous operations on behalf of a C++ program.
- * Notification that an asynchronous operation has completed is delivered by
- * invocation of the associated handler. Handlers are invoked only by a thread
- * that is currently calling any overload of run(), run_one(), run_for(),
- * run_until(), poll() or poll_one() for the io_context.
- *
- * @par Effect of exceptions thrown from handlers
- *
- * If an exception is thrown from a handler, the exception is allowed to
- * propagate through the throwing thread's invocation of run(), run_one(),
- * run_for(), run_until(), poll() or poll_one(). No other threads that are
- * calling any of these functions are affected. It is then the responsibility
- * of the application to catch the exception.
- *
- * After the exception has been caught, the run(), run_one(), run_for(),
- * run_until(), poll() or poll_one() call may be restarted @em without the need
- * for an intervening call to restart(). This allows the thread to rejoin the
- * io_context object's thread pool without impacting any other threads in the
- * pool.
- *
- * For example:
- *
- * @code
- * asio::io_context io_context;
- * ...
- * for (;;)
- * {
- *   try
- *   {
- *     io_context.run();
- *     break; // run() exited normally
- *   }
- *   catch (my_exception& e)
- *   {
- *     // Deal with exception as appropriate.
- *   }
- * }
- * @endcode
- *
- * @par Submitting arbitrary tasks to the io_context
- *
- * To submit functions to the io_context, use the @ref asio::dispatch,
- * @ref asio::post or @ref asio::defer free functions.
- *
- * For example:
- *
- * @code void my_task()
- * {
- *   ...
- * }
- *
- * ...
- *
- * asio::io_context io_context;
- *
- * // Submit a function to the io_context.
- * asio::post(io_context, my_task);
- *
- * // Submit a lambda object to the io_context.
- * asio::post(io_context,
- *     []()
- *     {
- *       ...
- *     });
- *
- * // Run the io_context until it runs out of work.
- * io_context.run(); @endcode
- *
- * @par Stopping the io_context from running out of work
- *
- * Some applications may need to prevent an io_context object's run() call from
- * returning when there is no more work to do. For example, the io_context may
- * be being run in a background thread that is launched prior to the
- * application's asynchronous operations. The run() call may be kept running by
- * creating an executor that tracks work against the io_context:
- *
- * @code asio::io_context io_context;
- * auto work = asio::require(io_context.get_executor(),
- *     asio::execution::outstanding_work.tracked);
- * ... @endcode
- *
- * If using C++03, which lacks automatic variable type deduction, you may
- * compute the return type of the require call:
- *
- * @code asio::io_context io_context;
- * typename asio::require_result<
- *     asio::io_context::executor_type,
- *     asio::exeution::outstanding_work_t::tracked_t>
- *   work = asio::require(io_context.get_executor(),
- *     asio::execution::outstanding_work.tracked);
- * ... @endcode
- *
- * or store the result in the type-erasing executor wrapper, any_io_executor:
- *
- * @code asio::io_context io_context;
- * asio::any_io_executor work
- *   = asio::require(io_context.get_executor(),
- *       asio::execution::outstanding_work.tracked);
- * ... @endcode
- *
- * To effect a shutdown, the application will then need to call the io_context
- * object's stop() member function. This will cause the io_context run() call
- * to return as soon as possible, abandoning unfinished operations and without
- * permitting ready handlers to be dispatched.
- *
- * Alternatively, if the application requires that all operations and handlers
- * be allowed to finish normally, store the work-tracking executor in an
- * any_io_executor object, so that it may be explicitly reset.
- *
- * @code asio::io_context io_context;
- * asio::any_io_executor work
- *   = asio::require(io_context.get_executor(),
- *       asio::execution::outstanding_work.tracked);
- * ...
- * work = asio::any_io_executor(); // Allow run() to exit. @endcode

- * The io_context::strand class provides the ability to post and dispatch
- * handlers with the guarantee that none of those handlers will execute
- * concurrently.
- *
- * @par Order of handler invocation
- * Given:
- *
- * @li a strand object @c s
- *
- * @li an object @c a meeting completion handler requirements
- *
- * @li an object @c a1 which is an arbitrary copy of @c a made by the
- * implementation
- *
- * @li an object @c b meeting completion handler requirements
- *
- * @li an object @c b1 which is an arbitrary copy of @c b made by the
- * implementation
- *
- * if any of the following conditions are true:
- *
- * @li @c s.post(a) happens-before @c s.post(b)
- * 
- * @li @c s.post(a) happens-before @c s.dispatch(b), where the latter is
- * performed outside the strand
- * 
- * @li @c s.dispatch(a) happens-before @c s.post(b), where the former is
- * performed outside the strand
- * 
- * @li @c s.dispatch(a) happens-before @c s.dispatch(b), where both are
- * performed outside the strand
- *   
- * then @c asio_handler_invoke(a1, &a1) happens-before
- * @c asio_handler_invoke(b1, &b1).
- * 
- * Note that in the following case:
- * @code async_op_1(..., s.wrap(a));
- * async_op_2(..., s.wrap(b)); @endcode
- * the completion of the first async operation will perform @c s.dispatch(a),
- * and the second will perform @c s.dispatch(b), but the order in which those
- * are performed is unspecified. That is, you cannot state whether one
- * happens-before the other. Therefore none of the above conditions are met and
- * no ordering guarantee is made.
- *
- * @note The implementation makes no guarantee that handlers posted or
- * dispatched through different @c strand objects will be invoked concurrently.
- *
- * @par Thread Safety
- * @e Distinct @e objects: Safe.@n
- * @e Shared @e objects: Safe.
- *
- * @par Concepts:
- * Dispatcher.

- * @li An error occurred.

- * The iterator parameters @c begin and @c end define the range of bytes to be
- * scanned to determine whether there is a match. The @c first member of the
- * return value is an iterator marking one-past-the-end of the bytes that have
- * been consumed by the match function. This iterator is used to calculate the
- * @c begin parameter for any subsequent invocation of the match condition. The
- * @c second member of the return value is true if a match has been found, false

- *
- * @returns The number of bytes in the streambuf's get area that have been fully
- * consumed by the match function.
- *
- * @throws asio::system_error Thrown on failure.
- *
- * @note After a successful read_until operation, the streambuf may contain
- * additional data beyond that which matched the function object. An application
- * will typically leave that data in the streambuf for a subsequent read_until
- * operation to examine.
- *

- * streambuf until the streambuf's get area contains the specified delimiter.
- * The function call always returns immediately. The asynchronous operation
- * will continue until one of the following conditions is true:
- *
- * @li The get area of the streambuf contains the specified delimiter.
- *
- * @li An error occurred.
- *
- * This operation is implemented in terms of zero or more calls to the stream's
- * async_read_some function, and is known as a <em>composed operation</em>. If
- * the streambuf's get area already contains the delimiter, this asynchronous
- * operation completes immediately. The program must ensure that the stream
- * performs no other read operations (such as async_read, async_read_until, the
- * stream's async_read_some function, or any other composed operations that
- * perform reads) until this operation completes.
- *
- * @param s The stream from which the data is to be read. The type must support
- * the AsyncReadStream concept.
- *
- * @param b A streambuf object into which the data will be read. Ownership of
- * the streambuf is retained by the caller, which must guarantee that it remains
- * valid until the handler is called.
- *
- * @param delim The delimiter string.
- *
- * @param handler The handler to be called when the read operation completes.
- * Copies will be made of the handler as required. The function signature of the
- * handler must be:
- * @code void handler(
- *   // Result of operation.
- *   const asio::error_code& error,
- *
- *   // The number of bytes in the streambuf's get
- *   // area up to and including the delimiter.
- *   // 0 if an error occurred.
- *   std::size_t bytes_transferred
- * ); @endcode
- * Regardless of whether the asynchronous operation completes immediately or
- * not, the handler will not be invoked from within this function. On
- * immediate completion, invocation of the handler will be performed in a
- * manner equivalent to using asio::post().
- *
- * @note After a successful async_read_until operation, the streambuf may
- * contain additional data beyond the delimiter. An application will typically
- * leave that data in the streambuf for a subsequent async_read_until operation
- * to examine.
- *
- * @par Example
- * To asynchronously read data into a streambuf until a newline is encountered:
- * @code asio::streambuf b;
- * ...
- * void handler(const asio::error_code& e, std::size_t size)
- * {
- *   if (!e)
- *   {
- *     std::istream is(&b);
- *     std::string line;
- *     std::getline(is, line);
- *     ...
- *   }
- * }
- * ...
- * asio::async_read_until(s, b, "\r\n", handler); @endcode
- * After the @c async_read_until operation completes successfully, the buffer
- * @c b contains the delimiter:
- * @code { 'a', 'b', ..., 'c', '\r', '\n', 'd', 'e', ... } @endcode
- * The call to @c std::getline then extracts the data up to and including the
- * newline (which is discarded), so that the string @c line contains:
- * @code { 'a', 'b', ..., 'c', '\r' } @endcode
- * The remaining data is left in the buffer @c b as follows:
- * @code { 'd', 'e', ... } @endcode
- * This data may be the start of a new line, to be extracted by a subsequent
- * @c async_read_until operation.

-/// Start an asynchronous operation to read data into a dynamic buffer sequence
-/// until a function object indicates a match.
-/**
- * This function is used to asynchronously read data into the specified dynamic
- * buffer sequence until a user-defined match condition function object, when
- * applied to the data contained in the dynamic buffer sequence, indicates a
- * successful match. The function call always returns immediately. The
- * asynchronous operation will continue until one of the following conditions
- * is true:
- *
- * @li The match condition function object returns a std::pair where the second
- * element evaluates to true.
- *
- * @li An error occurred.
- *
- * This operation is implemented in terms of zero or more calls to the stream's
- * async_read_some function, and is known as a <em>composed operation</em>. If
- * the match condition function object already indicates a match, this
- * asynchronous operation completes immediately. The program must ensure that
- * the stream performs no other read operations (such as async_read,
- * async_read_until, the stream's async_read_some function, or any other
- * composed operations that perform reads) until this operation completes.
- *
- * @param s The stream from which the data is to be read. The type must support
- * the AsyncReadStream concept.
- *
- * @param buffers The dynamic buffer sequence into which the data will be read.
- * Although the buffers object may be copied as necessary, ownership of the
- * underlying memory blocks is retained by the caller, which must guarantee
- * that they remain valid until the handler is called.
- *
- * @param match_condition The function object to be called to determine whether
- * a match exists. The signature of the function object must be:
- * @code pair<iterator, bool> match_condition(iterator begin, iterator end);
- * @endcode
- * where @c iterator represents the type:
- * @code buffers_iterator<typename DynamicBuffer_v2::const_buffers_type>
- * @endcode
- * The iterator parameters @c begin and @c end define the range of bytes to be
- * scanned to determine whether there is a match. The @c first member of the
- * return value is an iterator marking one-past-the-end of the bytes that have
- * been consumed by the match function. This iterator is used to calculate the
- * @c begin parameter for any subsequent invocation of the match condition. The
- * @c second member of the return value is true if a match has been found, false
- * otherwise.
- *
- * @param handler The handler to be called when the read operation completes.
- * Copies will be made of the handler as required. The function signature of the
- * handler must be:
- * @code void handler(
- *   // Result of operation.
- *   const asio::error_code& error,
- *
- *   // The number of bytes in the dynamic buffer sequence's
- *   // get area that have been fully consumed by the match
- *   // function. O if an error occurred.
- *   std::size_t bytes_transferred
- * ); @endcode
- * Regardless of whether the asynchronous operation completes immediately or
- * not, the handler will not be invoked from within this function. On
- * immediate completion, invocation of the handler will be performed in a
- * manner equivalent to using asio::post().
- *
- * @note After a successful async_read_until operation, the dynamic buffer
- * sequence may contain additional data beyond that which matched the function
- * object. An application will typically leave that data in the dynamic buffer
- * sequence for a subsequent async_read_until operation to examine.
- *
- * @note The default implementation of the @c is_match_condition type trait
- * evaluates to true for function pointers and function objects with a
- * @c result_type typedef. It must be specialised for other user-defined
- * function objects.
- *
- * @par Examples
- * To asynchronously read data into a @c std::string until whitespace is
- * encountered:
- * @code typedef asio::buffers_iterator<
- *     asio::const_buffers_1> iterator;
- *
- * std::pair<iterator, bool>
- * match_whitespace(iterator begin, iterator end)
- * {
- *   iterator i = begin;
- *   while (i != end)
- *     if (std::isspace(*i++))
- *       return std::make_pair(i, true);
- *   return std::make_pair(i, false);
- * }
- * ...
- * void handler(const asio::error_code& e, std::size_t size);
- * ...
- * std::string data;
- * asio::async_read_until(s, data, match_whitespace, handler);
- * @endcode
- *
- * To asynchronously read data into a @c std::string until a matching character
- * is found:
- * @code class match_char
- * {
- * public:
- *   explicit match_char(char c) : c_(c) {}
- *
- *   template <typename Iterator>
- *   std::pair<Iterator, bool> operator()(
- *       Iterator begin, Iterator end) const
- *   {
- *     Iterator i = begin;
- *     while (i != end)
- *       if (c_ == *i++)
- *         return std::make_pair(i, true);
- *     return std::make_pair(i, false);
- *   }
- *
- * private:
- *   char c_;
- * };
- *
- * namespace asio {
- *   template <> struct is_match_condition<match_char>
- *     : public boost::true_type {};

-// This class manages socket timeouts by applying the concept of a deadline.
-// Some asynchronous operations are given deadlines by which they must complete.
-// Deadlines are enforced by an "actor" that persists for the lifetime of the
-// client object:

-//  +----------------+
-//  |                |

-//              +---------+
-//
-// If the deadline actor determines that the deadline has expired, the socket
-// is closed and any outstanding operations are consequently cancelled.
-//
-// Connection establishment involves trying each endpoint in turn until a
-// connection is successful, or the available endpoints are exhausted. If the
-// deadline actor closes the socket, the connect actor is woken up and moves to
-// the next endpoint.
-//

-// This class manages socket timeouts by applying the concept of a deadline.
-// Some asynchronous operations are given deadlines by which they must complete.
-// Deadlines are enforced by an "actor" that persists for the lifetime of the
-// client object:

-//              +---------+
-//
-// If the deadline actor determines that the deadline has expired, the socket
-// is closed and any outstanding operations are consequently cancelled.
-//
-// Connection establishment involves trying each endpoint in turn until a
-// connection is successful, or the available endpoints are exhausted. If the
-// deadline actor closes the socket, the connect actor is woken up and moves to
-// the next endpoint.

-// This class manages socket timeouts by applying the concept of a deadline.

-//
-//  +----------------+                      +----------------+
-//  |                |                      |                |

-//                    +----------------+                      +----------------+
-//
-// If either deadline actor determines that the corresponding deadline has
-// expired, the socket is closed and any outstanding operations are cancelled.
-//
-// The input actor reads messages from the socket, where messages are delimited
-// by the newline character:
-//
-//  +-------------+
-//  |             |
-//  |  read_line  |<----+
-//  |             |     |

-//               |  read_line  |
-//               +-------------+
-//
-// The deadline for receiving a complete message is 30 seconds. If a non-empty
-// message is received, it is delivered to all subscribers. If a heartbeat (a
-// message that consists of a single newline character) is received, a heartbeat
-// is enqueued for the client, provided there are no other messages waiting to
-// be sent.
-//
-// The output actor is responsible for sending messages to the client:
-//

-// The output actor first waits for an output message to be enqueued. It does
-// this by using a steady_timer as an asynchronous condition variable. The
-// steady_timer will be signalled whenever the output queue is non-empty.
-//
-// Once a message is available, it is sent to the client. The deadline for
-// sending a complete message is 30 seconds. After the message is successfully
-// sent, the output actor again waits for the output queue to become non-empty.

-  // token to optimise how they are passed. For example, a lazy future which

-# How to become a contributor and submit your own code
-
-## Contributor License Agreements
-
-We'd love to accept your patches! Before we can take them, we
-have to jump a couple of legal hurdles.
-
-Please fill out either the individual or corporate Contributor License Agreement
-(CLA).
-
-  * If you are an individual writing original source code and you're sure you
-    own the intellectual property, then you'll need to sign an
-    [individual CLA](https://developers.google.com/open-source/cla/individual).
-  * If you work for a company that wants to allow you to contribute your work,
-    then you'll need to sign a
-    [corporate CLA](https://developers.google.com/open-source/cla/corporate).
-
-Follow either of the two links above to access the appropriate CLA and
-instructions for how to sign and return it. Once we receive it, we'll be able to
-accept your pull requests.
-
-## Are you a Googler?
-If you are a Googler, you can either create an internal change or work on GitHub directly.
-
-
-## Contributing A Patch
-
-1. Submit an issue describing your proposed change to the
-   [issue tracker](https://github.com/google/googletest).
-1. Please don't mix more than one logical change per submittal,
-   because it makes the history hard to follow. If you want to make a
-   change that doesn't have a corresponding issue in the issue
-   tracker, please create one.
-1. Also, coordinate with team members that are listed on the issue in
-   question. This ensures that work isn't being duplicated and
-   communicating your plan early also generally leads to better
-   patches.
-1. If your proposed change is accepted, and you haven't already done so, sign a
-   Contributor License Agreement (see details above).
-1. Fork the desired repo, develop and test your code changes.
-1. Ensure that your code adheres to the existing style in the sample to which
-   you are contributing.
-1. Ensure that your code has an appropriate set of unit tests which all pass.
-1. Submit a pull request.
-
-## The Google Test and Google Mock Communities ##
-
-The Google Test community exists primarily through the
-[discussion group](http://groups.google.com/group/googletestframework)
-and the GitHub repository.
-Likewise, the Google Mock community exists primarily through their own
-[discussion group](http://groups.google.com/group/googlemock).
-You are definitely encouraged to contribute to the
-discussion and you can also help us to keep the effectiveness of the
-group high by following and promoting the guidelines listed here.
-
-### Please Be Friendly ###
-
-Showing courtesy and respect to others is a vital part of the Google
-culture, and we strongly encourage everyone participating in Google
-Test development to join us in accepting nothing less. Of course,
-being courteous is not the same as failing to constructively disagree
-with each other, but it does mean that we should be respectful of each
-other when enumerating the 42 technical reasons that a particular
-proposal may not be the best choice. There's never a reason to be
-antagonistic or dismissive toward anyone who is sincerely trying to
-contribute to a discussion.
-
-Sure, C++ testing is serious business and all that, but it's also
-a lot of fun. Let's keep it that way. Let's strive to be one of the
-friendliest communities in all of open source.
-
-As always, discuss Google Test in the official GoogleTest discussion group.
-You don't have to actually submit code in order to sign up. Your participation
-itself is a valuable contribution.
-
-## Style
-
-To keep the source consistent, readable, diffable and easy to merge,
-we use a fairly rigid coding style, as defined by the [google-styleguide](https://github.com/google/styleguide) project.  All patches will be expected
-to conform to the style outlined [here](https://google.github.io/styleguide/cppguide.html).
-
-## Requirements for Contributors ###
-
-If you plan to contribute a patch, you need to build Google Test,
-Google Mock, and their own tests from a git checkout, which has
-further requirements:
-
-  * [Python](https://www.python.org/) v2.3 or newer (for running some of
-    the tests and re-generating certain source files from templates)
-  * [CMake](https://cmake.org/) v2.6.4 or newer
-  * [GNU Build System](https://en.wikipedia.org/wiki/GNU_Build_System)
-    including automake (>= 1.9), autoconf (>= 2.59), and
-    libtool / libtoolize.
-
-## Developing Google Test ##
-
-This section discusses how to make your own changes to Google Test.
-
-### Testing Google Test Itself ###
-
-To make sure your changes work as intended and don't break existing
-functionality, you'll want to compile and run Google Test's own tests.
-For that you can use CMake:
-
-    mkdir mybuild
-    cd mybuild
-    cmake -Dgtest_build_tests=ON ${GTEST_DIR}
-
-Make sure you have Python installed, as some of Google Test's tests
-are written in Python.  If the cmake command complains about not being
-able to find Python (`Could NOT find PythonInterp (missing:
-PYTHON_EXECUTABLE)`), try telling it explicitly where your Python
-executable can be found:
-
-    cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR}
-
-Next, you can build Google Test and all of its own tests.  On \*nix,
-this is usually done by 'make'.  To run the tests, do
-
-    make test
-
-All tests should pass.
-
-### Regenerating Source Files ##
-
-Some of Google Test's source files are generated from templates (not
-in the C++ sense) using a script.
-For example, the
-file include/gtest/internal/gtest-type-util.h.pump is used to generate
-gtest-type-util.h in the same directory.
-
-You don't need to worry about regenerating the source files
-unless you need to modify them.  You would then modify the
-corresponding `.pump` files and run the '[pump.py](googletest/scripts/pump.py)'
-generator script.  See the [Pump Manual](googletest/docs/PumpManual.md).
-
-## Developing Google Mock ###
-
-This section discusses how to make your own changes to Google Mock.
-
-#### Testing Google Mock Itself ####
-
-To make sure your changes work as intended and don't break existing
-functionality, you'll want to compile and run Google Test's own tests.
-For that you'll need Autotools.  First, make sure you have followed
-the instructions above to configure Google Mock.
-Then, create a build output directory and enter it.  Next,
-
-    ${GMOCK_DIR}/configure  # try --help for more info
-
-Once you have successfully configured Google Mock, the build steps are
-standard for GNU-style OSS packages.
-
-    make        # Standard makefile following GNU conventions
-    make check  # Builds and runs all tests - all should pass.
-
-Note that when building your project against Google Mock, you are building
-against Google Test as well.  There is no need to configure Google Test
-separately.

-**Future Plans**:
-* 1.8.x Release - the 1.8.x will be the last release that works with pre-C++11 compilers. The 1.8.x will not accept any requests for any new features and any bugfix requests will only be accepted if proven "critical"
-* Post 1.8.x - work to improve/cleanup/pay technical debt. When this work is completed there will be a 1.9.x tagged release
-* Post 1.9.x googletest will follow [Abseil Live at Head philosophy](https://abseil.io/about/philosophy)

-
-Welcome to **Google Test**, Google's C++ test framework!
-
-This repository is a merger of the formerly separate GoogleTest and
-GoogleMock projects. These were so closely related that it makes sense to
-maintain and release them together.
-
-Please see the project page above for more information as well as the
-mailing list for questions, discussions, and development.  There is
-also an IRC channel on [OFTC](https://webchat.oftc.net/) (irc.oftc.net) #gtest available.  Please
-join us!
-
-Getting started information for **Google Test** is available in the
-[Google Test Primer](googletest/docs/primer.md) documentation.
-
-**Google Mock** is an extension to Google Test for writing and using C++ mock
-classes.  See the separate [Google Mock documentation](googlemock/README.md).
-
-More detailed documentation for googletest (including build instructions) are
-in its interior [googletest/README.md](googletest/README.md) file.
-

-## Requirements ##
-
-Google Test is designed to have fairly minimal requirements to build
-and use with your projects, but there are some.  Currently, we support
-Linux, Windows, Mac OS X, and Cygwin.  We will also make our best
-effort to support other platforms (e.g. Solaris, AIX, and z/OS).
-However, since core members of the Google Test project have no access
-to these platforms, Google Test may have outstanding issues there.  If
-you notice any problems on your platform, please notify
-[googletestframework@googlegroups.com](https://groups.google.com/forum/#!forum/googletestframework). Patches for fixing them are
-even more welcome!
-
-### Linux Requirements ###
-
-These are the base requirements to build and use Google Test from a source
-package (as described below):
-
-  * GNU-compatible Make or gmake
-  * POSIX-standard shell
-  * POSIX(-2) Regular Expressions (regex.h)
-  * A C++98-standard-compliant compiler
-
-### Windows Requirements ###
-
-  * Microsoft Visual C++ 2015 or newer
-
-### Cygwin Requirements ###
-
-  * Cygwin v1.5.25-14 or newer

-Changes for 1.7.0:
-
-* All new improvements in Google Test 1.7.0.
-* New feature: matchers DoubleNear(), FloatNear(),
-  NanSensitiveDoubleNear(), NanSensitiveFloatNear(),
-  UnorderedElementsAre(), UnorderedElementsAreArray(), WhenSorted(),
-  WhenSortedBy(), IsEmpty(), and SizeIs().
-* Improvement: Google Mock can now be built as a DLL.
-* Improvement: when compiled by a C++11 compiler, matchers AllOf()
-  and AnyOf() can accept an arbitrary number of matchers.
-* Improvement: when compiled by a C++11 compiler, matchers
-  ElementsAreArray() can accept an initializer list.
-* Improvement: when exceptions are enabled, a mock method with no
-  default action now throws instead crashing the test.
-* Improvement: added class testing::StringMatchResultListener to aid
-  definition of composite matchers.
-* Improvement: function return types used in MOCK_METHOD*() macros can
-  now contain unprotected commas.
-* Improvement (potentially breaking): EXPECT_THAT() and ASSERT_THAT()
-  are now more strict in ensuring that the value type and the matcher
-  type are compatible, catching potential bugs in tests.
-* Improvement: Pointee() now works on an optional<T>.
-* Improvement: the ElementsAreArray() matcher can now take a vector or
-  iterator range as input, and makes a copy of its input elements
-  before the conversion to a Matcher.
-* Improvement: the Google Mock Generator can now generate mocks for
-  some class templates.
-* Bug fix: mock object destruction triggerred by another mock object's
-  destruction no longer hangs.
-* Improvement: Google Mock Doctor works better with newer Clang and
-  GCC now.
-* Compatibility fixes.
-* Bug/warning fixes.
-
-Changes for 1.6.0:
-
-* Compilation is much faster and uses much less memory, especially
-  when the constructor and destructor of a mock class are moved out of
-  the class body.
-* New matchers: Pointwise(), Each().
-* New actions: ReturnPointee() and ReturnRefOfCopy().
-* CMake support.
-* Project files for Visual Studio 2010.
-* AllOf() and AnyOf() can handle up-to 10 arguments now.
-* Google Mock doctor understands Clang error messages now.
-* SetArgPointee<> now accepts string literals.
-* gmock_gen.py handles storage specifier macros and template return
-  types now.
-* Compatibility fixes.
-* Bug fixes and implementation clean-ups.
-* Potentially incompatible changes: disables the harmful 'make install'
-  command in autotools.
-
-Potentially breaking changes:
-
-* The description string for MATCHER*() changes from Python-style
-  interpolation to an ordinary C++ string expression.
-* SetArgumentPointee is deprecated in favor of SetArgPointee.
-* Some non-essential project files for Visual Studio 2005 are removed.
-
-Changes for 1.5.0:
-
- * New feature: Google Mock can be safely used in multi-threaded tests
-   on platforms having pthreads.
- * New feature: function for printing a value of arbitrary type.
- * New feature: function ExplainMatchResult() for easy definition of
-   composite matchers.
- * The new matcher API lets user-defined matchers generate custom
-   explanations more directly and efficiently.
- * Better failure messages all around.
- * NotNull() and IsNull() now work with smart pointers.
- * Field() and Property() now work when the matcher argument is a pointer
-   passed by reference.
- * Regular expression matchers on all platforms.
- * Added GCC 4.0 support for Google Mock Doctor.
- * Added gmock_all_test.cc for compiling most Google Mock tests
-   in a single file.
- * Significantly cleaned up compiler warnings.
- * Bug fixes, better test coverage, and implementation clean-ups.
-
- Potentially breaking changes:
-
- * Custom matchers defined using MatcherInterface or MakePolymorphicMatcher()
-   need to be updated after upgrading to Google Mock 1.5.0; matchers defined
-   using MATCHER or MATCHER_P* aren't affected.
- * Dropped support for 'make install'.
-
-Changes for 1.4.0 (we skipped 1.2.* and 1.3.* to match the version of
-Google Test):
-
- * Works in more environments: Symbian and minGW, Visual C++ 7.1.
- * Lighter weight: comes with our own implementation of TR1 tuple (no
-   more dependency on Boost!).
- * New feature: --gmock_catch_leaked_mocks for detecting leaked mocks.
- * New feature: ACTION_TEMPLATE for defining templatized actions.
- * New feature: the .After() clause for specifying expectation order.
- * New feature: the .With() clause for specifying inter-argument
-   constraints.
- * New feature: actions ReturnArg<k>(), ReturnNew<T>(...), and

-## Google Mock ##
-
-The Google C++ mocking framework.
-
-### Overview ###
-
-Google's framework for writing and using C++ mock classes.
-It can help you derive better designs of your system and write better tests.
-
-It is inspired by:
-
-  * [jMock](http://www.jmock.org/),
-  * [EasyMock](http://www.easymock.org/), and
-  * [Hamcrest](http://code.google.com/p/hamcrest/),
-
-and designed with C++'s specifics in mind.
-
-Google mock:
-
-  * lets you create mock classes trivially using simple macros.
-  * supports a rich set of matchers and actions.
-  * handles unordered, partially ordered, or completely ordered expectations.
-  * is extensible by users.
-
-We hope you find it useful!
-
-### Features ###
-
-  * Provides a declarative syntax for defining mocks.
-  * Can easily define partial (hybrid) mocks, which are a cross of real
-    and mock objects.
-  * Handles functions of arbitrary types and overloaded functions.
-  * Comes with a rich set of matchers for validating function arguments.
-  * Uses an intuitive syntax for controlling the behavior of a mock.
-  * Does automatic verification of expectations (no record-and-replay needed).
-  * Allows arbitrary (partial) ordering constraints on
-    function calls to be expressed,.
-  * Lets an user extend it by defining new matchers and actions.
-  * Does not use exceptions.
-  * Is easy to learn and use.
-
-Please see the project page above for more information as well as the
-mailing list for questions, discussions, and development.  There is
-also an IRC channel on OFTC (irc.oftc.net) #gtest available.  Please
-join us!
-
-Please note that code under [scripts/generator](scripts/generator/) is
-from [cppclean](http://code.google.com/p/cppclean/) and released under
-the Apache License, which is different from Google Mock's license.
-
-## Getting Started ##
-
-If you are new to the project, we suggest that you read the user
-documentation in the following order:
-
-  * Learn the [basics](../../master/googletest/docs/primer.md) of
-    Google Test, if you choose to use Google Mock with it (recommended).
-  * Read [Google Mock for Dummies](../../master/googlemock/docs/ForDummies.md).
-  * Read the instructions below on how to build Google Mock.
-
-You can also watch Zhanyong's [talk](http://www.youtube.com/watch?v=sYpCyLI47rM) on Google Mock's usage and implementation.
-
-Once you understand the basics, check out the rest of the docs:
-
-  * [CheatSheet](../../master/googlemock/docs/CheatSheet.md) - all the commonly used stuff
-    at a glance.
-  * [CookBook](../../master/googlemock/docs/CookBook.md) - recipes for getting things done,
-    including advanced techniques.
-
-If you need help, please check the
-[KnownIssues](docs/KnownIssues.md) and
-[FrequentlyAskedQuestions](docs/FrequentlyAskedQuestions.md) before
-posting a question on the
-[discussion group](http://groups.google.com/group/googlemock).
-
-
-### Using Google Mock Without Google Test ###
-
-Google Mock is not a testing framework itself.  Instead, it needs a
-testing framework for writing tests.  Google Mock works seamlessly
-with [Google Test](https://github.com/google/googletest), but
-you can also use it with [any C++ testing framework](../../master/googlemock/docs/ForDummies.md#using-google-mock-with-any-testing-framework).
-
-### Requirements for End Users ###
-
-Google Mock is implemented on top of [Google Test](
-http://github.com/google/googletest/), and depends on it.
-You must use the bundled version of Google Test when using Google Mock.
-
-You can also easily configure Google Mock to work with another testing
-framework, although it will still need Google Test.  Please read
-["Using_Google_Mock_with_Any_Testing_Framework"](
-    ../../master/googlemock/docs/ForDummies.md#using-google-mock-with-any-testing-framework)
-for instructions.
-
-Google Mock depends on advanced C++ features and thus requires a more
-modern compiler. The following are needed to use Google Mock:
-
-#### Linux Requirements ####
-
-  * GNU-compatible Make or "gmake"
-  * POSIX-standard shell
-  * POSIX(-2) Regular Expressions (regex.h)
-  * C++98-standard-compliant compiler (e.g. GCC 3.4 or newer)
-
-#### Windows Requirements ####
-
-  * Microsoft Visual C++ 8.0 SP1 or newer
-
-#### Mac OS X Requirements ####
-
-  * Mac OS X 10.4 Tiger or newer
-  * Developer Tools Installed
-
-### Requirements for Contributors ###
-
-We welcome patches. If you plan to contribute a patch, you need to
-build Google Mock and its tests, which has further requirements:
-
-  * Automake version 1.9 or newer
-  * Autoconf version 2.59 or newer
-  * Libtool / Libtoolize
-  * Python version 2.3 or newer (for running some of the tests and
-    re-generating certain source files from templates)
-
-### Building Google Mock ###
-
-#### Using CMake ####
-
-If you have CMake available, it is recommended that you follow the
-[build instructions][gtest_cmakebuild]
-as described for Google Test.
-
-If are using Google Mock with an
-existing CMake project, the section
-[Incorporating Into An Existing CMake Project][gtest_incorpcmake]
-may be of particular interest.
-To make it work for Google Mock you will need to change
-
-    target_link_libraries(example gtest_main)
-
-to
-
-    target_link_libraries(example gmock_main)
-
-This works because `gmock_main` library is compiled with Google Test.
-
-#### Preparing to Build (Unix only) ####
-
-If you are using a Unix system and plan to use the GNU Autotools build
-system to build Google Mock (described below), you'll need to
-configure it now.
-
-To prepare the Autotools build system:
-
-    cd googlemock
-    autoreconf -fvi
-
-To build Google Mock and your tests that use it, you need to tell your
-build system where to find its headers and source files.  The exact
-way to do it depends on which build system you use, and is usually
-straightforward.
-
-This section shows how you can integrate Google Mock into your
-existing build system.
-
-Suppose you put Google Mock in directory `${GMOCK_DIR}` and Google Test
-in `${GTEST_DIR}` (the latter is `${GMOCK_DIR}/gtest` by default).  To
-build Google Mock, create a library build target (or a project as
-called by Visual Studio and Xcode) to compile
-
-    ${GTEST_DIR}/src/gtest-all.cc and ${GMOCK_DIR}/src/gmock-all.cc
-
-with
-
-    ${GTEST_DIR}/include and ${GMOCK_DIR}/include
-
-in the system header search path, and
-
-    ${GTEST_DIR} and ${GMOCK_DIR}
-
-in the normal header search path.  Assuming a Linux-like system and gcc,
-something like the following will do:
-
-    g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
-        -isystem ${GMOCK_DIR}/include -I${GMOCK_DIR} \
-        -pthread -c ${GTEST_DIR}/src/gtest-all.cc
-    g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
-        -isystem ${GMOCK_DIR}/include -I${GMOCK_DIR} \
-        -pthread -c ${GMOCK_DIR}/src/gmock-all.cc
-    ar -rv libgmock.a gtest-all.o gmock-all.o
-
-(We need -pthread as Google Test and Google Mock use threads.)
-
-Next, you should compile your test source file with
-${GTEST\_DIR}/include and ${GMOCK\_DIR}/include in the header search
-path, and link it with gmock and any other necessary libraries:
-
-    g++ -isystem ${GTEST_DIR}/include -isystem ${GMOCK_DIR}/include \
-        -pthread path/to/your_test.cc libgmock.a -o your_test
-
-As an example, the make/ directory contains a Makefile that you can
-use to build Google Mock on systems where GNU make is available
-(e.g. Linux, Mac OS X, and Cygwin).  It doesn't try to build Google
-Mock's own tests.  Instead, it just builds the Google Mock library and
-a sample test.  You can use it as a starting point for your own build
-script.
-
-If the default settings are correct for your environment, the
-following commands should succeed:
-
-    cd ${GMOCK_DIR}/make
-    make
-    ./gmock_test
-
-If you see errors, try to tweak the contents of
-[make/Makefile](make/Makefile) to make them go away.
-
-### Windows ###
-
-The msvc/2005 directory contains VC++ 2005 projects and the msvc/2010
-directory contains VC++ 2010 projects for building Google Mock and
-selected tests.
-
-Change to the appropriate directory and run "msbuild gmock.sln" to
-build the library and tests (or open the gmock.sln in the MSVC IDE).
-If you want to create your own project to use with Google Mock, you'll
-have to configure it to use the `gmock_config` propety sheet.  For that:
-
- * Open the Property Manager window (View | Other Windows | Property Manager)
- * Right-click on your project and select "Add Existing Property Sheet..."
- * Navigate to `gmock_config.vsprops` or `gmock_config.props` and select it.
- * In Project Properties | Configuration Properties | General | Additional
-   Include Directories, type <path to Google Mock>/include.
-
-### Tweaking Google Mock ###
-
-Google Mock can be used in diverse environments.  The default
-configuration may not work (or may not work well) out of the box in
-some environments.  However, you can easily tweak Google Mock by
-defining control macros on the compiler command line.  Generally,
-these macros are named like `GTEST_XYZ` and you define them to either 1
-or 0 to enable or disable a certain feature.
-
-We list the most frequently used macros below.  For a complete list,
-see file [${GTEST\_DIR}/include/gtest/internal/gtest-port.h](
-../googletest/include/gtest/internal/gtest-port.h).
-
-### Choosing a TR1 Tuple Library ###
-
-Google Mock uses the C++ Technical Report 1 (TR1) tuple library
-heavily.  Unfortunately TR1 tuple is not yet widely available with all
-compilers.  The good news is that Google Test 1.4.0+ implements a
-subset of TR1 tuple that's enough for Google Mock's need.  Google Mock
-will automatically use that implementation when the compiler doesn't
-provide TR1 tuple.
-
-Usually you don't need to care about which tuple library Google Test
-and Google Mock use.  However, if your project already uses TR1 tuple,
-you need to tell Google Test and Google Mock to use the same TR1 tuple
-library the rest of your project uses, or the two tuple
-implementations will clash.  To do that, add
-
-    -DGTEST_USE_OWN_TR1_TUPLE=0
-
-to the compiler flags while compiling Google Test, Google Mock, and
-your tests.  If you want to force Google Test and Google Mock to use
-their own tuple library, just add
-
-    -DGTEST_USE_OWN_TR1_TUPLE=1
-
-to the compiler flags instead.
-
-If you want to use Boost's TR1 tuple library with Google Mock, please
-refer to the Boost website (http://www.boost.org/) for how to obtain
-it and set it up.
-
-### As a Shared Library (DLL) ###
-
-Google Mock is compact, so most users can build and link it as a static
-library for the simplicity.  Google Mock can be used as a DLL, but the
-same DLL must contain Google Test as well.  See
-[Google Test's README][gtest_readme]
-for instructions on how to set up necessary compiler settings.
-
-### Tweaking Google Mock ###
-
-Most of Google Test's control macros apply to Google Mock as well.
-Please see [Google Test's README][gtest_readme] for how to tweak them.
-
-### Upgrading from an Earlier Version ###
-
-We strive to keep Google Mock releases backward compatible.
-Sometimes, though, we have to make some breaking changes for the
-users' long-term benefits.  This section describes what you'll need to
-do if you are upgrading from an earlier version of Google Mock.
-
-#### Upgrading from 1.1.0 or Earlier ####
-
-You may need to explicitly enable or disable Google Test's own TR1
-tuple library.  See the instructions in section "[Choosing a TR1 Tuple
-Library](../googletest/#choosing-a-tr1-tuple-library)".
-
-#### Upgrading from 1.4.0 or Earlier ####
-
-On platforms where the pthread library is available, Google Test and
-Google Mock use it in order to be thread-safe.  For this to work, you
-may need to tweak your compiler and/or linker flags.  Please see the
-"[Multi-threaded Tests](../googletest#multi-threaded-tests
-)" section in file Google Test's README for what you may need to do.
-
-If you have custom matchers defined using `MatcherInterface` or
-`MakePolymorphicMatcher()`, you'll need to update their definitions to
-use the new matcher API (
-[monomorphic](./docs/CookBook.md#writing-new-monomorphic-matchers),
-[polymorphic](./docs/CookBook.md#writing-new-polymorphic-matchers)).
-Matchers defined using `MATCHER()` or `MATCHER_P*()` aren't affected.
-
-Happy testing!

-  virtual int GetSize() const = 0;
-  virtual string Describe(const char* name) = 0;
-  virtual string Describe(int type) = 0;
-  virtual bool Process(Bar elem, int count) = 0;
-};
-```
-(note that `~Foo()` **must** be virtual) we can define its mock as
-```
-#include "gmock/gmock.h"
-
-class MockFoo : public Foo {
-  MOCK_CONST_METHOD0(GetSize, int());
-  MOCK_METHOD1(Describe, string(const char* name));
-  MOCK_METHOD1(Describe, string(int type));
-  MOCK_METHOD2(Process, bool(Bar elem, int count));
-};
-```
-
-To create a "nice" mock object which ignores all uninteresting calls,
-or a "strict" mock object, which treats them as failures:
-```
-NiceMock<MockFoo> nice_foo;     // The type is a subclass of MockFoo.
-StrictMock<MockFoo> strict_foo; // The type is a subclass of MockFoo.
-```
-
-## Mocking a Class Template ##
-
-To mock
-```
-template <typename Elem>
-class StackInterface {
- public:
-  ...
-  virtual ~StackInterface();
-  virtual int GetSize() const = 0;
-  virtual void Push(const Elem& x) = 0;
-};
-```
-(note that `~StackInterface()` **must** be virtual) just append `_T` to the `MOCK_*` macros:
-```
-template <typename Elem>
-class MockStack : public StackInterface<Elem> {
- public:
-  ...
-  MOCK_CONST_METHOD0_T(GetSize, int());
-  MOCK_METHOD1_T(Push, void(const Elem& x));
-};
-```
-
-## Specifying Calling Conventions for Mock Functions ##
-
-If your mock function doesn't use the default calling convention, you
-can specify it by appending `_WITH_CALLTYPE` to any of the macros
-described in the previous two sections and supplying the calling
-convention as the first argument to the macro. For example,
-```
-  MOCK_METHOD1_WITH_CALLTYPE(STDMETHODCALLTYPE, Foo, bool(int n));
-  MOCK_CONST_METHOD2_WITH_CALLTYPE(STDMETHODCALLTYPE, Bar, int(double x, double y));
-```
-where `STDMETHODCALLTYPE` is defined by `<objbase.h>` on Windows.
-
-# Using Mocks in Tests #
-
-The typical flow is:
-  1. Import the Google Mock names you need to use. All Google Mock names are in the `testing` namespace unless they are macros or otherwise noted.
-  1. Create the mock objects.
-  1. Optionally, set the default actions of the mock objects.
-  1. Set your expectations on the mock objects (How will they be called? What wil they do?).
-  1. Exercise code that uses the mock objects; if necessary, check the result using [Google Test](../../googletest/) assertions.
-  1. When a mock objects is destructed, Google Mock automatically verifies that all expectations on it have been satisfied.
-
-Here is an example:
-```
-using ::testing::Return;                            // #1
-
-TEST(BarTest, DoesThis) {
-  MockFoo foo;                                    // #2
-
-  ON_CALL(foo, GetSize())                         // #3
-      .WillByDefault(Return(1));
-  // ... other default actions ...
-
-  EXPECT_CALL(foo, Describe(5))                   // #4
-      .Times(3)
-      .WillRepeatedly(Return("Category 5"));
-  // ... other expectations ...
-
-  EXPECT_EQ("good", MyProductionFunction(&foo));  // #5
-}                                                 // #6
-```
-
-# Setting Default Actions #
-
-Google Mock has a **built-in default action** for any function that
-returns `void`, `bool`, a numeric value, or a pointer.
-
-To customize the default action for functions with return type `T` globally:
-```
-using ::testing::DefaultValue;
-
-// Sets the default value to be returned. T must be CopyConstructible.
-DefaultValue<T>::Set(value);
-// Sets a factory. Will be invoked on demand. T must be MoveConstructible.
-//   T MakeT();
-DefaultValue<T>::SetFactory(&MakeT);
-// ... use the mocks ...
-// Resets the default value.
-DefaultValue<T>::Clear();
-```
-
-To customize the default action for a particular method, use `ON_CALL()`:
-```
-ON_CALL(mock_object, method(matchers))
-    .With(multi_argument_matcher)  ?
-    .WillByDefault(action);
-```
-
-# Setting Expectations #
-
-`EXPECT_CALL()` sets **expectations** on a mock method (How will it be
-called? What will it do?):
-```
-EXPECT_CALL(mock_object, method(matchers))
-    .With(multi_argument_matcher)  ?
-    .Times(cardinality)            ?
-    .InSequence(sequences)         *
-    .After(expectations)           *
-    .WillOnce(action)              *
-    .WillRepeatedly(action)        ?
-    .RetiresOnSaturation();        ?
-```
-
-If `Times()` is omitted, the cardinality is assumed to be:
-
-  * `Times(1)` when there is neither `WillOnce()` nor `WillRepeatedly()`;
-  * `Times(n)` when there are `n WillOnce()`s but no `WillRepeatedly()`, where `n` >= 1; or
-  * `Times(AtLeast(n))` when there are `n WillOnce()`s and a `WillRepeatedly()`, where `n` >= 0.
-
-A method with no `EXPECT_CALL()` is free to be invoked _any number of times_, and the default action will be taken each time.
-
-# Matchers #
-
-A **matcher** matches a _single_ argument.  You can use it inside
-`ON_CALL()` or `EXPECT_CALL()`, or use it to validate a value
-directly:
-
-| `EXPECT_THAT(value, matcher)` | Asserts that `value` matches `matcher`. |
-|:------------------------------|:----------------------------------------|
-| `ASSERT_THAT(value, matcher)` | The same as `EXPECT_THAT(value, matcher)`, except that it generates a **fatal** failure. |
-
-Built-in matchers (where `argument` is the function argument) are
-divided into several categories:
-
-## Wildcard ##
-|`_`|`argument` can be any value of the correct type.|
-|:--|:-----------------------------------------------|
-|`A<type>()` or `An<type>()`|`argument` can be any value of type `type`.     |
-
-## Generic Comparison ##
-
-|`Eq(value)` or `value`|`argument == value`|
-|:---------------------|:------------------|
-|`Ge(value)`           |`argument >= value`|
-|`Gt(value)`           |`argument > value` |
-|`Le(value)`           |`argument <= value`|
-|`Lt(value)`           |`argument < value` |
-|`Ne(value)`           |`argument != value`|
-|`IsNull()`            |`argument` is a `NULL` pointer (raw or smart).|
-|`NotNull()`           |`argument` is a non-null pointer (raw or smart).|
-|`VariantWith<T>(m)`   |`argument` is `variant<>` that holds the alternative of
-type T with a value matching `m`.|
-|`Ref(variable)`       |`argument` is a reference to `variable`.|
-|`TypedEq<type>(value)`|`argument` has type `type` and is equal to `value`. You may need to use this instead of `Eq(value)` when the mock function is overloaded.|
-
-Except `Ref()`, these matchers make a _copy_ of `value` in case it's
-modified or destructed later. If the compiler complains that `value`
-doesn't have a public copy constructor, try wrap it in `ByRef()`,
-e.g. `Eq(ByRef(non_copyable_value))`. If you do that, make sure
-`non_copyable_value` is not changed afterwards, or the meaning of your
-matcher will be changed.
-
-## Floating-Point Matchers ##
-
-|`DoubleEq(a_double)`|`argument` is a `double` value approximately equal to `a_double`, treating two NaNs as unequal.|
-|:-------------------|:----------------------------------------------------------------------------------------------|
-|`FloatEq(a_float)`  |`argument` is a `float` value approximately equal to `a_float`, treating two NaNs as unequal.  |
-|`NanSensitiveDoubleEq(a_double)`|`argument` is a `double` value approximately equal to `a_double`, treating two NaNs as equal.  |
-|`NanSensitiveFloatEq(a_float)`|`argument` is a `float` value approximately equal to `a_float`, treating two NaNs as equal.    |
-
-The above matchers use ULP-based comparison (the same as used in
-[Google Test](../../googletest/)). They
-automatically pick a reasonable error bound based on the absolute
-value of the expected value.  `DoubleEq()` and `FloatEq()` conform to
-the IEEE standard, which requires comparing two NaNs for equality to
-return false. The `NanSensitive*` version instead treats two NaNs as
-equal, which is often what a user wants.
-
-|`DoubleNear(a_double, max_abs_error)`|`argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as unequal.|
-|:------------------------------------|:--------------------------------------------------------------------------------------------------------------------|
-|`FloatNear(a_float, max_abs_error)`  |`argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as unequal.  |
-|`NanSensitiveDoubleNear(a_double, max_abs_error)`|`argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as equal.  |
-|`NanSensitiveFloatNear(a_float, max_abs_error)`|`argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as equal.    |
-
-## String Matchers ##
-
-The `argument` can be either a C string or a C++ string object:
-
-|`ContainsRegex(string)`|`argument` matches the given regular expression.|
-|:----------------------|:-----------------------------------------------|
-|`EndsWith(suffix)`     |`argument` ends with string `suffix`.           |
-|`HasSubstr(string)`    |`argument` contains `string` as a sub-string.   |
-|`MatchesRegex(string)` |`argument` matches the given regular expression with the match starting at the first character and ending at the last character.|
-|`StartsWith(prefix)`   |`argument` starts with string `prefix`.         |
-|`StrCaseEq(string)`    |`argument` is equal to `string`, ignoring case. |
-|`StrCaseNe(string)`    |`argument` is not equal to `string`, ignoring case.|
-|`StrEq(string)`        |`argument` is equal to `string`.                |
-|`StrNe(string)`        |`argument` is not equal to `string`.            |
-
-`ContainsRegex()` and `MatchesRegex()` use the regular expression
-syntax defined
-[here](../../googletest/docs/advanced.md#regular-expression-syntax).
-`StrCaseEq()`, `StrCaseNe()`, `StrEq()`, and `StrNe()` work for wide
-strings as well.
-
-## Container Matchers ##
-
-Most STL-style containers support `==`, so you can use
-`Eq(expected_container)` or simply `expected_container` to match a
-container exactly.   If you want to write the elements in-line,
-match them more flexibly, or get more informative messages, you can use:
-
-| `ContainerEq(container)` | The same as `Eq(container)` except that the failure message also includes which elements are in one container but not the other. |
-|:-------------------------|:---------------------------------------------------------------------------------------------------------------------------------|
-| `Contains(e)`            | `argument` contains an element that matches `e`, which can be either a value or a matcher.                                       |
-| `Each(e)`                | `argument` is a container where _every_ element matches `e`, which can be either a value or a matcher.                           |
-| `ElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, where the i-th element matches `ei`, which can be a value or a matcher. 0 to 10 arguments are allowed. |
-| `ElementsAreArray({ e0, e1, ..., en })`, `ElementsAreArray(array)`, or `ElementsAreArray(array, count)` | The same as `ElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, or C-style array. |
-| `IsEmpty()`              | `argument` is an empty container (`container.empty()`).                                                                          |
-| `Pointwise(m, container)` | `argument` contains the same number of elements as in `container`, and for all i, (the i-th element in `argument`, the i-th element in `container`) match `m`, which is a matcher on 2-tuples. E.g. `Pointwise(Le(), upper_bounds)` verifies that each element in `argument` doesn't exceed the corresponding element in `upper_bounds`. See more detail below. |
-| `SizeIs(m)`              | `argument` is a container whose size matches `m`. E.g. `SizeIs(2)` or `SizeIs(Lt(2))`.                                           |
-| `UnorderedElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, and under some permutation each element matches an `ei` (for a different `i`), which can be a value or a matcher. 0 to 10 arguments are allowed. |
-| `UnorderedElementsAreArray({ e0, e1, ..., en })`, `UnorderedElementsAreArray(array)`, or `UnorderedElementsAreArray(array, count)` | The same as `UnorderedElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, or C-style array. |
-| `WhenSorted(m)`          | When `argument` is sorted using the `<` operator, it matches container matcher `m`. E.g. `WhenSorted(ElementsAre(1, 2, 3))` verifies that `argument` contains elements `1`, `2`, and `3`, ignoring order. |
-| `WhenSortedBy(comparator, m)` | The same as `WhenSorted(m)`, except that the given comparator instead of `<` is used to sort `argument`. E.g. `WhenSortedBy(std::greater<int>(), ElementsAre(3, 2, 1))`. |
-
-Notes:
-
-  * These matchers can also match:
-    1. a native array passed by reference (e.g. in `Foo(const int (&a)[5])`), and
-    1. an array passed as a pointer and a count (e.g. in `Bar(const T* buffer, int len)` -- see [Multi-argument Matchers](#Multiargument_Matchers.md)).
-  * The array being matched may be multi-dimensional (i.e. its elements can be arrays).
-  * `m` in `Pointwise(m, ...)` should be a matcher for `::testing::tuple<T, U>` where `T` and `U` are the element type of the actual container and the expected container, respectively. For example, to compare two `Foo` containers where `Foo` doesn't support `operator==` but has an `Equals()` method, one might write:
-
-```
-using ::testing::get;
-MATCHER(FooEq, "") {
-  return get<0>(arg).Equals(get<1>(arg));
-}
-...
-EXPECT_THAT(actual_foos, Pointwise(FooEq(), expected_foos));
-```
-
-## Member Matchers ##
-
-|`Field(&class::field, m)`|`argument.field` (or `argument->field` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_.|
-|:------------------------|:---------------------------------------------------------------------------------------------------------------------------------------------|
-|`Key(e)`                 |`argument.first` matches `e`, which can be either a value or a matcher. E.g. `Contains(Key(Le(5)))` can verify that a `map` contains a key `<= 5`.|
-|`Pair(m1, m2)`           |`argument` is an `std::pair` whose `first` field matches `m1` and `second` field matches `m2`.                                                |
-|`Property(&class::property, m)`|`argument.property()` (or `argument->property()` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_.|
-
-## Matching the Result of a Function or Functor ##
-
-|`ResultOf(f, m)`|`f(argument)` matches matcher `m`, where `f` is a function or functor.|
-|:---------------|:---------------------------------------------------------------------|
-
-## Pointer Matchers ##
-
-|`Pointee(m)`|`argument` (either a smart pointer or a raw pointer) points to a value that matches matcher `m`.|
-|:-----------|:-----------------------------------------------------------------------------------------------|
-|`WhenDynamicCastTo<T>(m)`| when `argument` is passed through `dynamic_cast<T>()`, it matches matcher `m`.                 |
-
-## Multiargument Matchers ##
-
-Technically, all matchers match a _single_ value. A "multi-argument"
-matcher is just one that matches a _tuple_. The following matchers can
-be used to match a tuple `(x, y)`:
-
-|`Eq()`|`x == y`|
-|:-----|:-------|
-|`Ge()`|`x >= y`|
-|`Gt()`|`x > y` |
-|`Le()`|`x <= y`|
-|`Lt()`|`x < y` |
-|`Ne()`|`x != y`|
-
-You can use the following selectors to pick a subset of the arguments
-(or reorder them) to participate in the matching:
-
-|`AllArgs(m)`|Equivalent to `m`. Useful as syntactic sugar in `.With(AllArgs(m))`.|
-|:-----------|:-------------------------------------------------------------------|
-|`Args<N1, N2, ..., Nk>(m)`|The tuple of the `k` selected (using 0-based indices) arguments matches `m`, e.g. `Args<1, 2>(Eq())`.|
-
-## Composite Matchers ##
-
-You can make a matcher from one or more other matchers:
-
-|`AllOf(m1, m2, ..., mn)`|`argument` matches all of the matchers `m1` to `mn`.|
-|:-----------------------|:---------------------------------------------------|
-|`AnyOf(m1, m2, ..., mn)`|`argument` matches at least one of the matchers `m1` to `mn`.|
-|`Not(m)`                |`argument` doesn't match matcher `m`.               |
-
-## Adapters for Matchers ##
-
-|`MatcherCast<T>(m)`|casts matcher `m` to type `Matcher<T>`.|
-|:------------------|:--------------------------------------|
-|`SafeMatcherCast<T>(m)`| [safely casts](CookBook.md#casting-matchers) matcher `m` to type `Matcher<T>`. |
-|`Truly(predicate)` |`predicate(argument)` returns something considered by C++ to be true, where `predicate` is a function or functor.|
-
-## Matchers as Predicates ##
-
-|`Matches(m)(value)`|evaluates to `true` if `value` matches `m`. You can use `Matches(m)` alone as a unary functor.|
-|:------------------|:---------------------------------------------------------------------------------------------|
-|`ExplainMatchResult(m, value, result_listener)`|evaluates to `true` if `value` matches `m`, explaining the result to `result_listener`.       |
-|`Value(value, m)`  |evaluates to `true` if `value` matches `m`.                                                   |
-
-## Defining Matchers ##
-
-| `MATCHER(IsEven, "") { return (arg % 2) == 0; }` | Defines a matcher `IsEven()` to match an even number. |
-|:-------------------------------------------------|:------------------------------------------------------|
-| `MATCHER_P(IsDivisibleBy, n, "") { *result_listener << "where the remainder is " << (arg % n); return (arg % n) == 0; }` | Defines a macher `IsDivisibleBy(n)` to match a number divisible by `n`. |
-| `MATCHER_P2(IsBetween, a, b, std::string(negation ? "isn't" : "is") + " between " + PrintToString(a) + " and " + PrintToString(b)) { return a <= arg && arg <= b; }` | Defines a matcher `IsBetween(a, b)` to match a value in the range [`a`, `b`]. |
-
-**Notes:**
-
-  1. The `MATCHER*` macros cannot be used inside a function or class.
-  1. The matcher body must be _purely functional_ (i.e. it cannot have any side effect, and the result must not depend on anything other than the value being matched and the matcher parameters).
-  1. You can use `PrintToString(x)` to convert a value `x` of any type to a string.
-
-## Matchers as Test Assertions ##
-
-|`ASSERT_THAT(expression, m)`|Generates a [fatal failure](../../googletest/docs/primer.md#assertions) if the value of `expression` doesn't match matcher `m`.|
-|:---------------------------|:----------------------------------------------------------------------------------------------------------------------------------------------|
-|`EXPECT_THAT(expression, m)`|Generates a non-fatal failure if the value of `expression` doesn't match matcher `m`.                                                          |
-
-# Actions #
-
-**Actions** specify what a mock function should do when invoked.
-
-## Returning a Value ##
-
-|`Return()`|Return from a `void` mock function.|
-|:---------|:----------------------------------|
-|`Return(value)`|Return `value`. If the type of `value` is different to the mock function's return type, `value` is converted to the latter type <i>at the time the expectation is set</i>, not when the action is executed.|
-|`ReturnArg<N>()`|Return the `N`-th (0-based) argument.|
-|`ReturnNew<T>(a1, ..., ak)`|Return `new T(a1, ..., ak)`; a different object is created each time.|
-|`ReturnNull()`|Return a null pointer.             |
-|`ReturnPointee(ptr)`|Return the value pointed to by `ptr`.|
-|`ReturnRef(variable)`|Return a reference to `variable`.  |
-|`ReturnRefOfCopy(value)`|Return a reference to a copy of `value`; the copy lives as long as the action.|
-
-## Side Effects ##
-
-|`Assign(&variable, value)`|Assign `value` to variable.|
-|:-------------------------|:--------------------------|
-| `DeleteArg<N>()`         | Delete the `N`-th (0-based) argument, which must be a pointer. |
-| `SaveArg<N>(pointer)`    | Save the `N`-th (0-based) argument to `*pointer`. |
-| `SaveArgPointee<N>(pointer)` | Save the value pointed to by the `N`-th (0-based) argument to `*pointer`. |
-| `SetArgReferee<N>(value)` |	Assign value to the variable referenced by the `N`-th (0-based) argument. |
-|`SetArgPointee<N>(value)` |Assign `value` to the variable pointed by the `N`-th (0-based) argument.|
-|`SetArgumentPointee<N>(value)`|Same as `SetArgPointee<N>(value)`. Deprecated. Will be removed in v1.7.0.|
-|`SetArrayArgument<N>(first, last)`|Copies the elements in source range [`first`, `last`) to the array pointed to by the `N`-th (0-based) argument, which can be either a pointer or an iterator. The action does not take ownership of the elements in the source range.|
-|`SetErrnoAndReturn(error, value)`|Set `errno` to `error` and return `value`.|
-|`Throw(exception)`        |Throws the given exception, which can be any copyable value. Available since v1.1.0.|
-
-## Using a Function or a Functor as an Action ##
-
-|`Invoke(f)`|Invoke `f` with the arguments passed to the mock function, where `f` can be a global/static function or a functor.|
-|:----------|:-----------------------------------------------------------------------------------------------------------------|
-|`Invoke(object_pointer, &class::method)`|Invoke the {method on the object with the arguments passed to the mock function.                                  |
-|`InvokeWithoutArgs(f)`|Invoke `f`, which can be a global/static function or a functor. `f` must take no arguments.                       |
-|`InvokeWithoutArgs(object_pointer, &class::method)`|Invoke the method on the object, which takes no arguments.                                                        |
-|`InvokeArgument<N>(arg1, arg2, ..., argk)`|Invoke the mock function's `N`-th (0-based) argument, which must be a function or a functor, with the `k` arguments.|
-
-The return value of the invoked function is used as the return value
-of the action.
-
-When defining a function or functor to be used with `Invoke*()`, you can declare any unused parameters as `Unused`:
-```
-  double Distance(Unused, double x, double y) { return sqrt(x*x + y*y); }
-  ...
-  EXPECT_CALL(mock, Foo("Hi", _, _)).WillOnce(Invoke(Distance));
-```
-
-In `InvokeArgument<N>(...)`, if an argument needs to be passed by reference, wrap it inside `ByRef()`. For example,
-```
-  InvokeArgument<2>(5, string("Hi"), ByRef(foo))
-```
-calls the mock function's #2 argument, passing to it `5` and `string("Hi")` by value, and `foo` by reference.
-
-## Default Action ##
-
-|`DoDefault()`|Do the default action (specified by `ON_CALL()` or the built-in one).|
-|:------------|:--------------------------------------------------------------------|
-
-**Note:** due to technical reasons, `DoDefault()` cannot be used inside  a composite action - trying to do so will result in a run-time error.
-
-## Composite Actions ##
-
-|`DoAll(a1, a2, ..., an)`|Do all actions `a1` to `an` and return the result of `an` in each invocation. The first `n - 1` sub-actions must return void. |
-|:-----------------------|:-----------------------------------------------------------------------------------------------------------------------------|
-|`IgnoreResult(a)`       |Perform action `a` and ignore its result. `a` must not return void.                                                           |
-|`WithArg<N>(a)`         |Pass the `N`-th (0-based) argument of the mock function to action `a` and perform it.                                         |
-|`WithArgs<N1, N2, ..., Nk>(a)`|Pass the selected (0-based) arguments of the mock function to action `a` and perform it.                                      |
-|`WithoutArgs(a)`        |Perform action `a` without any arguments.                                                                                     |
-
-## Defining Actions ##
-
-| `ACTION(Sum) { return arg0 + arg1; }` | Defines an action `Sum()` to return the sum of the mock function's argument #0 and #1. |
-|:--------------------------------------|:---------------------------------------------------------------------------------------|
-| `ACTION_P(Plus, n) { return arg0 + n; }` | Defines an action `Plus(n)` to return the sum of the mock function's argument #0 and `n`. |
-| `ACTION_Pk(Foo, p1, ..., pk) { statements; }` | Defines a parameterized action `Foo(p1, ..., pk)` to execute the given `statements`.   |
-
-The `ACTION*` macros cannot be used inside a function or class.
-
-# Cardinalities #
-
-These are used in `Times()` to specify how many times a mock function will be called:
-
-|`AnyNumber()`|The function can be called any number of times.|
-|:------------|:----------------------------------------------|
-|`AtLeast(n)` |The call is expected at least `n` times.       |
-|`AtMost(n)`  |The call is expected at most `n` times.        |
-|`Between(m, n)`|The call is expected between `m` and `n` (inclusive) times.|
-|`Exactly(n) or n`|The call is expected exactly `n` times. In particular, the call should never happen when `n` is 0.|
-
-# Expectation Order #
-
-By default, the expectations can be matched in _any_ order.  If some
-or all expectations must be matched in a given order, there are two
-ways to specify it.  They can be used either independently or
-together.
-
-## The After Clause ##
-
-```
-using ::testing::Expectation;
-...
-Expectation init_x = EXPECT_CALL(foo, InitX());
-Expectation init_y = EXPECT_CALL(foo, InitY());
-EXPECT_CALL(foo, Bar())
-    .After(init_x, init_y);
-```
-says that `Bar()` can be called only after both `InitX()` and
-`InitY()` have been called.
-
-If you don't know how many pre-requisites an expectation has when you
-write it, you can use an `ExpectationSet` to collect them:
-
-```
-using ::testing::ExpectationSet;
-...
-ExpectationSet all_inits;
-for (int i = 0; i < element_count; i++) {
-  all_inits += EXPECT_CALL(foo, InitElement(i));
-}
-EXPECT_CALL(foo, Bar())
-    .After(all_inits);
-```
-says that `Bar()` can be called only after all elements have been
-initialized (but we don't care about which elements get initialized
-before the others).
-
-Modifying an `ExpectationSet` after using it in an `.After()` doesn't
-affect the meaning of the `.After()`.
-
-## Sequences ##
-
-When you have a long chain of sequential expectations, it's easier to
-specify the order using **sequences**, which don't require you to given
-each expectation in the chain a different name.  <i>All expected<br>
-calls</i> in the same sequence must occur in the order they are
-specified.
-
-```
-using ::testing::Sequence;
-Sequence s1, s2;
-...
-EXPECT_CALL(foo, Reset())
-    .InSequence(s1, s2)
-    .WillOnce(Return(true));
-EXPECT_CALL(foo, GetSize())
-    .InSequence(s1)
-    .WillOnce(Return(1));
-EXPECT_CALL(foo, Describe(A<const char*>()))
-    .InSequence(s2)
-    .WillOnce(Return("dummy"));
-```
-says that `Reset()` must be called before _both_ `GetSize()` _and_
-`Describe()`, and the latter two can occur in any order.
-
-To put many expectations in a sequence conveniently:
-```
-using ::testing::InSequence;
-{
-  InSequence dummy;
-
-  EXPECT_CALL(...)...;
-  EXPECT_CALL(...)...;
-  ...
-  EXPECT_CALL(...)...;
-}
-```
-says that all expected calls in the scope of `dummy` must occur in
-strict order. The name `dummy` is irrelevant.)
-
-# Verifying and Resetting a Mock #
-
-Google Mock will verify the expectations on a mock object when it is destructed, or you can do it earlier:
-```
-using ::testing::Mock;
-...
-// Verifies and removes the expectations on mock_obj;
-// returns true iff successful.
-Mock::VerifyAndClearExpectations(&mock_obj);
-...
-// Verifies and removes the expectations on mock_obj;
-// also removes the default actions set by ON_CALL();
-// returns true iff successful.
-Mock::VerifyAndClear(&mock_obj);
-```
-
-You can also tell Google Mock that a mock object can be leaked and doesn't
-need to be verified:
-```
-Mock::AllowLeak(&mock_obj);
-```
-
-# Mock Classes #
-
-Google Mock defines a convenient mock class template
-```
-class MockFunction<R(A1, ..., An)> {
- public:
-  MOCK_METHODn(Call, R(A1, ..., An));
-};
-```
-See this [recipe](CookBook.md#using-check-points) for one application of it.
-
-# Flags #
-
-| `--gmock_catch_leaked_mocks=0` | Don't report leaked mock objects as failures. |
-|:-------------------------------|:----------------------------------------------|
-| `--gmock_verbose=LEVEL`        | Sets the default verbosity level (`info`, `warning`, or `error`) of Google Mock messages. |

-You can find recipes for using Google Mock here. If you haven't yet,
-please read the [ForDummies](ForDummies.md) document first to make sure you understand
-the basics.
-
-**Note:** Google Mock lives in the `testing` name space. For
-readability, it is recommended to write `using ::testing::Foo;` once in
-your file before using the name `Foo` defined by Google Mock. We omit
-such `using` statements in this page for brevity, but you should do it
-in your own code.
-
-# Creating Mock Classes #
-
-## Mocking Private or Protected Methods ##
-
-You must always put a mock method definition (`MOCK_METHOD*`) in a
-`public:` section of the mock class, regardless of the method being
-mocked being `public`, `protected`, or `private` in the base class.
-This allows `ON_CALL` and `EXPECT_CALL` to reference the mock function
-from outside of the mock class.  (Yes, C++ allows a subclass to specify
-a different access level than the base class on a virtual function.)
-Example:
-
-```
-class Foo {
- public:
-  ...
-  virtual bool Transform(Gadget* g) = 0;
-
- protected:
-  virtual void Resume();
-
- private:
-  virtual int GetTimeOut();
-};
-
-class MockFoo : public Foo {
- public:
-  ...
-  MOCK_METHOD1(Transform, bool(Gadget* g));
-
-  // The following must be in the public section, even though the
-  // methods are protected or private in the base class.
-  MOCK_METHOD0(Resume, void());
-  MOCK_METHOD0(GetTimeOut, int());
-};
-```
-
-## Mocking Overloaded Methods ##
-
-You can mock overloaded functions as usual. No special attention is required:
-
-```
-class Foo {
-  ...
-
-  // Must be virtual as we'll inherit from Foo.
-  virtual ~Foo();
-
-  // Overloaded on the types and/or numbers of arguments.
-  virtual int Add(Element x);
-  virtual int Add(int times, Element x);
-
-  // Overloaded on the const-ness of this object.
-  virtual Bar& GetBar();
-  virtual const Bar& GetBar() const;
-};
-
-class MockFoo : public Foo {
-  ...
-  MOCK_METHOD1(Add, int(Element x));
-  MOCK_METHOD2(Add, int(int times, Element x);
-
-  MOCK_METHOD0(GetBar, Bar&());
-  MOCK_CONST_METHOD0(GetBar, const Bar&());
-};
-```
-
-**Note:** if you don't mock all versions of the overloaded method, the
-compiler will give you a warning about some methods in the base class
-being hidden. To fix that, use `using` to bring them in scope:
-
-```
-class MockFoo : public Foo {
-  ...
-  using Foo::Add;
-  MOCK_METHOD1(Add, int(Element x));
-  // We don't want to mock int Add(int times, Element x);
-  ...
-};
-```
-
-## Mocking Class Templates ##
-
-To mock a class template, append `_T` to the `MOCK_*` macros:
-
-```
-template <typename Elem>
-class StackInterface {
-  ...
-  // Must be virtual as we'll inherit from StackInterface.
-  virtual ~StackInterface();
-
-  virtual int GetSize() const = 0;
-  virtual void Push(const Elem& x) = 0;
-};
-
-template <typename Elem>
-class MockStack : public StackInterface<Elem> {
-  ...
-  MOCK_CONST_METHOD0_T(GetSize, int());
-  MOCK_METHOD1_T(Push, void(const Elem& x));
-};
-```
-
-## Mocking Nonvirtual Methods ##
-
-Google Mock can mock non-virtual functions to be used in what we call _hi-perf
-dependency injection_.
-
-In this case, instead of sharing a common base class with the real
-class, your mock class will be _unrelated_ to the real class, but
-contain methods with the same signatures.  The syntax for mocking
-non-virtual methods is the _same_ as mocking virtual methods:
-
-```
-// A simple packet stream class.  None of its members is virtual.
-class ConcretePacketStream {
- public:
-  void AppendPacket(Packet* new_packet);
-  const Packet* GetPacket(size_t packet_number) const;
-  size_t NumberOfPackets() const;
-  ...
-};
-
-// A mock packet stream class.  It inherits from no other, but defines
-// GetPacket() and NumberOfPackets().
-class MockPacketStream {
- public:
-  MOCK_CONST_METHOD1(GetPacket, const Packet*(size_t packet_number));
-  MOCK_CONST_METHOD0(NumberOfPackets, size_t());
-  ...
-};
-```
-
-Note that the mock class doesn't define `AppendPacket()`, unlike the
-real class. That's fine as long as the test doesn't need to call it.
-
-Next, you need a way to say that you want to use
-`ConcretePacketStream` in production code and to use `MockPacketStream`
-in tests.  Since the functions are not virtual and the two classes are
-unrelated, you must specify your choice at _compile time_ (as opposed
-to run time).
-
-One way to do it is to templatize your code that needs to use a packet
-stream.  More specifically, you will give your code a template type
-argument for the type of the packet stream.  In production, you will
-instantiate your template with `ConcretePacketStream` as the type
-argument.  In tests, you will instantiate the same template with
-`MockPacketStream`.  For example, you may write:
-
-```
-template <class PacketStream>
-void CreateConnection(PacketStream* stream) { ... }
-
-template <class PacketStream>
-class PacketReader {
- public:
-  void ReadPackets(PacketStream* stream, size_t packet_num);
-};
-```
-
-Then you can use `CreateConnection<ConcretePacketStream>()` and
-`PacketReader<ConcretePacketStream>` in production code, and use
-`CreateConnection<MockPacketStream>()` and
-`PacketReader<MockPacketStream>` in tests.
-
-```
-  MockPacketStream mock_stream;
-  EXPECT_CALL(mock_stream, ...)...;
-  .. set more expectations on mock_stream ...
-  PacketReader<MockPacketStream> reader(&mock_stream);
-  ... exercise reader ...
-```
-
-## Mocking Free Functions ##
-
-It's possible to use Google Mock to mock a free function (i.e. a
-C-style function or a static method).  You just need to rewrite your
-code to use an interface (abstract class).
-
-Instead of calling a free function (say, `OpenFile`) directly,
-introduce an interface for it and have a concrete subclass that calls
-the free function:
-
-```
-class FileInterface {
- public:
-  ...
-  virtual bool Open(const char* path, const char* mode) = 0;
-};
-
-class File : public FileInterface {
- public:
-  ...
-  virtual bool Open(const char* path, const char* mode) {
-    return OpenFile(path, mode);
-  }
-};
-```
-
-Your code should talk to `FileInterface` to open a file.  Now it's
-easy to mock out the function.
-
-This may seem much hassle, but in practice you often have multiple
-related functions that you can put in the same interface, so the
-per-function syntactic overhead will be much lower.
-
-If you are concerned about the performance overhead incurred by
-virtual functions, and profiling confirms your concern, you can
-combine this with the recipe for [mocking non-virtual methods](#mocking-nonvirtual-methods).
-
-## The Nice, the Strict, and the Naggy ##
-
-If a mock method has no `EXPECT_CALL` spec but is called, Google Mock
-will print a warning about the "uninteresting call". The rationale is:
-
-  * New methods may be added to an interface after a test is written. We shouldn't fail a test just because a method it doesn't know about is called.
-  * However, this may also mean there's a bug in the test, so Google Mock shouldn't be silent either. If the user believes these calls are harmless, they can add an `EXPECT_CALL()` to suppress the warning.
-
-However, sometimes you may want to suppress all "uninteresting call"
-warnings, while sometimes you may want the opposite, i.e. to treat all
-of them as errors. Google Mock lets you make the decision on a
-per-mock-object basis.
-
-Suppose your test uses a mock class `MockFoo`:
-
-```
-TEST(...) {
-  MockFoo mock_foo;
-  EXPECT_CALL(mock_foo, DoThis());
-  ... code that uses mock_foo ...
-}
-```
-
-If a method of `mock_foo` other than `DoThis()` is called, it will be
-reported by Google Mock as a warning. However, if you rewrite your
-test to use `NiceMock<MockFoo>` instead, the warning will be gone,
-resulting in a cleaner test output:
-
-```
-using ::testing::NiceMock;
-
-TEST(...) {
-  NiceMock<MockFoo> mock_foo;
-  EXPECT_CALL(mock_foo, DoThis());
-  ... code that uses mock_foo ...
-}
-```
-
-`NiceMock<MockFoo>` is a subclass of `MockFoo`, so it can be used
-wherever `MockFoo` is accepted.
-
-It also works if `MockFoo`'s constructor takes some arguments, as
-`NiceMock<MockFoo>` "inherits" `MockFoo`'s constructors:
-
-```
-using ::testing::NiceMock;
-
-TEST(...) {
-  NiceMock<MockFoo> mock_foo(5, "hi");  // Calls MockFoo(5, "hi").
-  EXPECT_CALL(mock_foo, DoThis());
-  ... code that uses mock_foo ...
-}
-```
-
-The usage of `StrictMock` is similar, except that it makes all
-uninteresting calls failures:
-
-```
-using ::testing::StrictMock;
-
-TEST(...) {
-  StrictMock<MockFoo> mock_foo;
-  EXPECT_CALL(mock_foo, DoThis());
-  ... code that uses mock_foo ...
-
-  // The test will fail if a method of mock_foo other than DoThis()
-  // is called.
-}
-```
-
-There are some caveats though (I don't like them just as much as the
-next guy, but sadly they are side effects of C++'s limitations):
-
-  1. `NiceMock<MockFoo>` and `StrictMock<MockFoo>` only work for mock methods defined using the `MOCK_METHOD*` family of macros **directly** in the `MockFoo` class. If a mock method is defined in a **base class** of `MockFoo`, the "nice" or "strict" modifier may not affect it, depending on the compiler. In particular, nesting `NiceMock` and `StrictMock` (e.g. `NiceMock<StrictMock<MockFoo> >`) is **not** supported.
-  1. The constructors of the base mock (`MockFoo`) cannot have arguments passed by non-const reference, which happens to be banned by the [Google C++ style guide](https://google.github.io/styleguide/cppguide.html).
-  1. During the constructor or destructor of `MockFoo`, the mock object is _not_ nice or strict.  This may cause surprises if the constructor or destructor calls a mock method on `this` object. (This behavior, however, is consistent with C++'s general rule: if a constructor or destructor calls a virtual method of `this` object, that method is treated as non-virtual.  In other words, to the base class's constructor or destructor, `this` object behaves like an instance of the base class, not the derived class.  This rule is required for safety.  Otherwise a base constructor may use members of a derived class before they are initialized, or a base destructor may use members of a derived class after they have been destroyed.)
-
-Finally, you should be **very cautious** about when to use naggy or strict mocks, as they tend to make tests more brittle and harder to maintain. When you refactor your code without changing its externally visible behavior, ideally you should't need to update any tests. If your code interacts with a naggy mock, however, you may start to get spammed with warnings as the result of your change. Worse, if your code interacts with a strict mock, your tests may start to fail and you'll be forced to fix them. Our general recommendation is to use nice mocks (not yet the default) most of the time, use naggy mocks (the current default) when developing or debugging tests, and use strict mocks only as the last resort.
-
-## Simplifying the Interface without Breaking Existing Code ##
-
-Sometimes a method has a long list of arguments that is mostly
-uninteresting. For example,
-
-```
-class LogSink {
- public:
-  ...
-  virtual void send(LogSeverity severity, const char* full_filename,
-                    const char* base_filename, int line,
-                    const struct tm* tm_time,
-                    const char* message, size_t message_len) = 0;
-};
-```
-
-This method's argument list is lengthy and hard to work with (let's
-say that the `message` argument is not even 0-terminated). If we mock
-it as is, using the mock will be awkward. If, however, we try to
-simplify this interface, we'll need to fix all clients depending on
-it, which is often infeasible.
-
-The trick is to re-dispatch the method in the mock class:
-
-```
-class ScopedMockLog : public LogSink {
- public:
-  ...
-  virtual void send(LogSeverity severity, const char* full_filename,
-                    const char* base_filename, int line, const tm* tm_time,
-                    const char* message, size_t message_len) {
-    // We are only interested in the log severity, full file name, and
-    // log message.
-    Log(severity, full_filename, std::string(message, message_len));
-  }
-
-  // Implements the mock method:
-  //
-  //   void Log(LogSeverity severity,
-  //            const string& file_path,
-  //            const string& message);
-  MOCK_METHOD3(Log, void(LogSeverity severity, const string& file_path,
-                         const string& message));
-};
-```
-
-By defining a new mock method with a trimmed argument list, we make
-the mock class much more user-friendly.
-
-## Alternative to Mocking Concrete Classes ##
-
-Often you may find yourself using classes that don't implement
-interfaces. In order to test your code that uses such a class (let's
-call it `Concrete`), you may be tempted to make the methods of
-`Concrete` virtual and then mock it.
-
-Try not to do that.
-
-Making a non-virtual function virtual is a big decision. It creates an
-extension point where subclasses can tweak your class' behavior. This
-weakens your control on the class because now it's harder to maintain
-the class' invariants. You should make a function virtual only when
-there is a valid reason for a subclass to override it.
-
-Mocking concrete classes directly is problematic as it creates a tight
-coupling between the class and the tests - any small change in the
-class may invalidate your tests and make test maintenance a pain.
-
-To avoid such problems, many programmers have been practicing "coding
-to interfaces": instead of talking to the `Concrete` class, your code
-would define an interface and talk to it. Then you implement that
-interface as an adaptor on top of `Concrete`. In tests, you can easily
-mock that interface to observe how your code is doing.
-
-This technique incurs some overhead:
-
-  * You pay the cost of virtual function calls (usually not a problem).
-  * There is more abstraction for the programmers to learn.
-
-However, it can also bring significant benefits in addition to better
-testability:
-
-  * `Concrete`'s API may not fit your problem domain very well, as you may not be the only client it tries to serve. By designing your own interface, you have a chance to tailor it to your need - you may add higher-level functionalities, rename stuff, etc instead of just trimming the class. This allows you to write your code (user of the interface) in a more natural way, which means it will be more readable, more maintainable, and you'll be more productive.
-  * If `Concrete`'s implementation ever has to change, you don't have to rewrite everywhere it is used. Instead, you can absorb the change in your implementation of the interface, and your other code and tests will be insulated from this change.
-
-Some people worry that if everyone is practicing this technique, they
-will end up writing lots of redundant code. This concern is totally
-understandable. However, there are two reasons why it may not be the
-case:
-
-  * Different projects may need to use `Concrete` in different ways, so the best interfaces for them will be different. Therefore, each of them will have its own domain-specific interface on top of `Concrete`, and they will not be the same code.
-  * If enough projects want to use the same interface, they can always share it, just like they have been sharing `Concrete`. You can check in the interface and the adaptor somewhere near `Concrete` (perhaps in a `contrib` sub-directory) and let many projects use it.
-
-You need to weigh the pros and cons carefully for your particular
-problem, but I'd like to assure you that the Java community has been
-practicing this for a long time and it's a proven effective technique
-applicable in a wide variety of situations. :-)
-
-## Delegating Calls to a Fake ##
-
-Some times you have a non-trivial fake implementation of an
-interface. For example:
-
-```
-class Foo {
- public:
-  virtual ~Foo() {}
-  virtual char DoThis(int n) = 0;
-  virtual void DoThat(const char* s, int* p) = 0;
-};
-
-class FakeFoo : public Foo {
- public:
-  virtual char DoThis(int n) {
-    return (n > 0) ? '+' :
-        (n < 0) ? '-' : '0';
-  }
-
-  virtual void DoThat(const char* s, int* p) {
-    *p = strlen(s);
-  }
-};
-```
-
-Now you want to mock this interface such that you can set expectations
-on it. However, you also want to use `FakeFoo` for the default
-behavior, as duplicating it in the mock object is, well, a lot of
-work.
-
-When you define the mock class using Google Mock, you can have it
-delegate its default action to a fake class you already have, using
-this pattern:
-
-```
-using ::testing::_;
-using ::testing::Invoke;
-
-class MockFoo : public Foo {
- public:
-  // Normal mock method definitions using Google Mock.
-  MOCK_METHOD1(DoThis, char(int n));
-  MOCK_METHOD2(DoThat, void(const char* s, int* p));
-
-  // Delegates the default actions of the methods to a FakeFoo object.
-  // This must be called *before* the custom ON_CALL() statements.
-  void DelegateToFake() {
-    ON_CALL(*this, DoThis(_))
-        .WillByDefault(Invoke(&fake_, &FakeFoo::DoThis));
-    ON_CALL(*this, DoThat(_, _))
-        .WillByDefault(Invoke(&fake_, &FakeFoo::DoThat));
-  }
- private:
-  FakeFoo fake_;  // Keeps an instance of the fake in the mock.
-};
-```
-
-With that, you can use `MockFoo` in your tests as usual. Just remember
-that if you don't explicitly set an action in an `ON_CALL()` or
-`EXPECT_CALL()`, the fake will be called upon to do it:
-
-```
-using ::testing::_;
-
-TEST(AbcTest, Xyz) {
-  MockFoo foo;
-  foo.DelegateToFake(); // Enables the fake for delegation.
-
-  // Put your ON_CALL(foo, ...)s here, if any.
-
-  // No action specified, meaning to use the default action.
-  EXPECT_CALL(foo, DoThis(5));
-  EXPECT_CALL(foo, DoThat(_, _));
-
-  int n = 0;
-  EXPECT_EQ('+', foo.DoThis(5));  // FakeFoo::DoThis() is invoked.
-  foo.DoThat("Hi", &n);           // FakeFoo::DoThat() is invoked.
-  EXPECT_EQ(2, n);
-}
-```
-
-**Some tips:**
-
-  * If you want, you can still override the default action by providing your own `ON_CALL()` or using `.WillOnce()` / `.WillRepeatedly()` in `EXPECT_CALL()`.
-  * In `DelegateToFake()`, you only need to delegate the methods whose fake implementation you intend to use.
-  * The general technique discussed here works for overloaded methods, but you'll need to tell the compiler which version you mean. To disambiguate a mock function (the one you specify inside the parentheses of `ON_CALL()`), see the "Selecting Between Overloaded Functions" section on this page; to disambiguate a fake function (the one you place inside `Invoke()`), use a `static_cast` to specify the function's type. For instance, if class `Foo` has methods `char DoThis(int n)` and `bool DoThis(double x) const`, and you want to invoke the latter, you need to write `Invoke(&fake_, static_cast<bool (FakeFoo::*)(double) const>(&FakeFoo::DoThis))` instead of `Invoke(&fake_, &FakeFoo::DoThis)` (The strange-looking thing inside the angled brackets of `static_cast` is the type of a function pointer to the second `DoThis()` method.).
-  * Having to mix a mock and a fake is often a sign of something gone wrong. Perhaps you haven't got used to the interaction-based way of testing yet. Or perhaps your interface is taking on too many roles and should be split up. Therefore, **don't abuse this**. We would only recommend to do it as an intermediate step when you are refactoring your code.
-
-Regarding the tip on mixing a mock and a fake, here's an example on
-why it may be a bad sign: Suppose you have a class `System` for
-low-level system operations. In particular, it does file and I/O
-operations. And suppose you want to test how your code uses `System`
-to do I/O, and you just want the file operations to work normally. If
-you mock out the entire `System` class, you'll have to provide a fake
-implementation for the file operation part, which suggests that
-`System` is taking on too many roles.
-
-Instead, you can define a `FileOps` interface and an `IOOps` interface
-and split `System`'s functionalities into the two. Then you can mock
-`IOOps` without mocking `FileOps`.
-
-## Delegating Calls to a Real Object ##
-
-When using testing doubles (mocks, fakes, stubs, and etc), sometimes
-their behaviors will differ from those of the real objects. This
-difference could be either intentional (as in simulating an error such
-that you can test the error handling code) or unintentional. If your
-mocks have different behaviors than the real objects by mistake, you
-could end up with code that passes the tests but fails in production.
-
-You can use the _delegating-to-real_ technique to ensure that your
-mock has the same behavior as the real object while retaining the
-ability to validate calls. This technique is very similar to the
-delegating-to-fake technique, the difference being that we use a real
-object instead of a fake. Here's an example:
-
-```
-using ::testing::_;
-using ::testing::AtLeast;
-using ::testing::Invoke;
-
-class MockFoo : public Foo {
- public:
-  MockFoo() {
-    // By default, all calls are delegated to the real object.
-    ON_CALL(*this, DoThis())
-        .WillByDefault(Invoke(&real_, &Foo::DoThis));
-    ON_CALL(*this, DoThat(_))
-        .WillByDefault(Invoke(&real_, &Foo::DoThat));
-    ...
-  }
-  MOCK_METHOD0(DoThis, ...);
-  MOCK_METHOD1(DoThat, ...);
-  ...
- private:
-  Foo real_;
-};
-...
-
-  MockFoo mock;
-
-  EXPECT_CALL(mock, DoThis())
-      .Times(3);
-  EXPECT_CALL(mock, DoThat("Hi"))
-      .Times(AtLeast(1));
-  ... use mock in test ...
-```
-
-With this, Google Mock will verify that your code made the right calls
-(with the right arguments, in the right order, called the right number
-of times, etc), and a real object will answer the calls (so the
-behavior will be the same as in production). This gives you the best
-of both worlds.
-
-## Delegating Calls to a Parent Class ##
-
-Ideally, you should code to interfaces, whose methods are all pure
-virtual. In reality, sometimes you do need to mock a virtual method
-that is not pure (i.e, it already has an implementation). For example:
-
-```
-class Foo {
- public:
-  virtual ~Foo();
-
-  virtual void Pure(int n) = 0;
-  virtual int Concrete(const char* str) { ... }
-};
-
-class MockFoo : public Foo {
- public:
-  // Mocking a pure method.
-  MOCK_METHOD1(Pure, void(int n));
-  // Mocking a concrete method.  Foo::Concrete() is shadowed.
-  MOCK_METHOD1(Concrete, int(const char* str));
-};
-```
-
-Sometimes you may want to call `Foo::Concrete()` instead of
-`MockFoo::Concrete()`. Perhaps you want to do it as part of a stub
-action, or perhaps your test doesn't need to mock `Concrete()` at all
-(but it would be oh-so painful to have to define a new mock class
-whenever you don't need to mock one of its methods).
-
-The trick is to leave a back door in your mock class for accessing the
-real methods in the base class:
-
-```
-class MockFoo : public Foo {
- public:
-  // Mocking a pure method.
-  MOCK_METHOD1(Pure, void(int n));
-  // Mocking a concrete method.  Foo::Concrete() is shadowed.
-  MOCK_METHOD1(Concrete, int(const char* str));
-
-  // Use this to call Concrete() defined in Foo.
-  int FooConcrete(const char* str) { return Foo::Concrete(str); }
-};
-```
-
-Now, you can call `Foo::Concrete()` inside an action by:
-
-```
-using ::testing::_;
-using ::testing::Invoke;
-...
-  EXPECT_CALL(foo, Concrete(_))
-      .WillOnce(Invoke(&foo, &MockFoo::FooConcrete));
-```
-
-or tell the mock object that you don't want to mock `Concrete()`:
-
-```
-using ::testing::Invoke;
-...
-  ON_CALL(foo, Concrete(_))
-      .WillByDefault(Invoke(&foo, &MockFoo::FooConcrete));
-```
-
-(Why don't we just write `Invoke(&foo, &Foo::Concrete)`? If you do
-that, `MockFoo::Concrete()` will be called (and cause an infinite
-recursion) since `Foo::Concrete()` is virtual. That's just how C++
-works.)
-
-# Using Matchers #
-
-## Matching Argument Values Exactly ##
-
-You can specify exactly which arguments a mock method is expecting:
-
-```
-using ::testing::Return;
-...
-  EXPECT_CALL(foo, DoThis(5))
-      .WillOnce(Return('a'));
-  EXPECT_CALL(foo, DoThat("Hello", bar));
-```
-
-## Using Simple Matchers ##
-
-You can use matchers to match arguments that have a certain property:
-
-```
-using ::testing::Ge;
-using ::testing::NotNull;
-using ::testing::Return;
-...
-  EXPECT_CALL(foo, DoThis(Ge(5)))  // The argument must be >= 5.
-      .WillOnce(Return('a'));
-  EXPECT_CALL(foo, DoThat("Hello", NotNull()));
-  // The second argument must not be NULL.
-```
-
-A frequently used matcher is `_`, which matches anything:
-
-```
-using ::testing::_;
-using ::testing::NotNull;
-...
-  EXPECT_CALL(foo, DoThat(_, NotNull()));
-```
-
-## Combining Matchers ##
-
-You can build complex matchers from existing ones using `AllOf()`,
-`AnyOf()`, and `Not()`:
-
-```
-using ::testing::AllOf;
-using ::testing::Gt;
-using ::testing::HasSubstr;
-using ::testing::Ne;
-using ::testing::Not;
-...
-  // The argument must be > 5 and != 10.
-  EXPECT_CALL(foo, DoThis(AllOf(Gt(5),
-                                Ne(10))));
-
-  // The first argument must not contain sub-string "blah".
-  EXPECT_CALL(foo, DoThat(Not(HasSubstr("blah")),
-                          NULL));
-```
-
-## Casting Matchers ##
-
-Google Mock matchers are statically typed, meaning that the compiler
-can catch your mistake if you use a matcher of the wrong type (for
-example, if you use `Eq(5)` to match a `string` argument). Good for
-you!
-
-Sometimes, however, you know what you're doing and want the compiler
-to give you some slack. One example is that you have a matcher for
-`long` and the argument you want to match is `int`. While the two
-types aren't exactly the same, there is nothing really wrong with
-using a `Matcher<long>` to match an `int` - after all, we can first
-convert the `int` argument to a `long` before giving it to the
-matcher.
-
-To support this need, Google Mock gives you the
-`SafeMatcherCast<T>(m)` function. It casts a matcher `m` to type
-`Matcher<T>`. To ensure safety, Google Mock checks that (let `U` be the
-type `m` accepts):
-
-  1. Type `T` can be implicitly cast to type `U`;
-  1. When both `T` and `U` are built-in arithmetic types (`bool`, integers, and floating-point numbers), the conversion from `T` to `U` is not lossy (in other words, any value representable by `T` can also be represented by `U`); and
-  1. When `U` is a reference, `T` must also be a reference (as the underlying matcher may be interested in the address of the `U` value).
-
-The code won't compile if any of these conditions aren't met.
-
-Here's one example:
-
-```
-using ::testing::SafeMatcherCast;
-
-// A base class and a child class.
-class Base { ... };
-class Derived : public Base { ... };
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD1(DoThis, void(Derived* derived));
-};
-...
-
-  MockFoo foo;
-  // m is a Matcher<Base*> we got from somewhere.
-  EXPECT_CALL(foo, DoThis(SafeMatcherCast<Derived*>(m)));
-```
-
-If you find `SafeMatcherCast<T>(m)` too limiting, you can use a similar
-function `MatcherCast<T>(m)`. The difference is that `MatcherCast` works
-as long as you can `static_cast` type `T` to type `U`.
-
-`MatcherCast` essentially lets you bypass C++'s type system
-(`static_cast` isn't always safe as it could throw away information,
-for example), so be careful not to misuse/abuse it.
-
-## Selecting Between Overloaded Functions ##
-
-If you expect an overloaded function to be called, the compiler may
-need some help on which overloaded version it is.
-
-To disambiguate functions overloaded on the const-ness of this object,
-use the `Const()` argument wrapper.
-
-```
-using ::testing::ReturnRef;
-
-class MockFoo : public Foo {
-  ...
-  MOCK_METHOD0(GetBar, Bar&());
-  MOCK_CONST_METHOD0(GetBar, const Bar&());
-};
-...
-
-  MockFoo foo;
-  Bar bar1, bar2;
-  EXPECT_CALL(foo, GetBar())         // The non-const GetBar().
-      .WillOnce(ReturnRef(bar1));
-  EXPECT_CALL(Const(foo), GetBar())  // The const GetBar().
-      .WillOnce(ReturnRef(bar2));
-```
-
-(`Const()` is defined by Google Mock and returns a `const` reference
-to its argument.)
-
-To disambiguate overloaded functions with the same number of arguments
-but different argument types, you may need to specify the exact type
-of a matcher, either by wrapping your matcher in `Matcher<type>()`, or
-using a matcher whose type is fixed (`TypedEq<type>`, `An<type>()`,
-etc):
-
-```
-using ::testing::An;
-using ::testing::Lt;
-using ::testing::Matcher;
-using ::testing::TypedEq;
-
-class MockPrinter : public Printer {
- public:
-  MOCK_METHOD1(Print, void(int n));
-  MOCK_METHOD1(Print, void(char c));
-};
-
-TEST(PrinterTest, Print) {
-  MockPrinter printer;
-
-  EXPECT_CALL(printer, Print(An<int>()));            // void Print(int);
-  EXPECT_CALL(printer, Print(Matcher<int>(Lt(5))));  // void Print(int);
-  EXPECT_CALL(printer, Print(TypedEq<char>('a')));   // void Print(char);
-
-  printer.Print(3);
-  printer.Print(6);
-  printer.Print('a');
-}
-```
-
-## Performing Different Actions Based on the Arguments ##
-
-When a mock method is called, the _last_ matching expectation that's
-still active will be selected (think "newer overrides older"). So, you
-can make a method do different things depending on its argument values
-like this:
-
-```
-using ::testing::_;
-using ::testing::Lt;
-using ::testing::Return;
-...
-  // The default case.
-  EXPECT_CALL(foo, DoThis(_))
-      .WillRepeatedly(Return('b'));
-
-  // The more specific case.
-  EXPECT_CALL(foo, DoThis(Lt(5)))
-      .WillRepeatedly(Return('a'));
-```
-
-Now, if `foo.DoThis()` is called with a value less than 5, `'a'` will
-be returned; otherwise `'b'` will be returned.
-
-## Matching Multiple Arguments as a Whole ##
-
-Sometimes it's not enough to match the arguments individually. For
-example, we may want to say that the first argument must be less than
-the second argument. The `With()` clause allows us to match
-all arguments of a mock function as a whole. For example,
-
-```
-using ::testing::_;
-using ::testing::Lt;
-using ::testing::Ne;
-...
-  EXPECT_CALL(foo, InRange(Ne(0), _))
-      .With(Lt());
-```
-
-says that the first argument of `InRange()` must not be 0, and must be
-less than the second argument.
-
-The expression inside `With()` must be a matcher of type
-`Matcher< ::testing::tuple<A1, ..., An> >`, where `A1`, ..., `An` are the
-types of the function arguments.
-
-You can also write `AllArgs(m)` instead of `m` inside `.With()`. The
-two forms are equivalent, but `.With(AllArgs(Lt()))` is more readable
-than `.With(Lt())`.
-
-You can use `Args<k1, ..., kn>(m)` to match the `n` selected arguments
-(as a tuple) against `m`. For example,
-
-```
-using ::testing::_;
-using ::testing::AllOf;
-using ::testing::Args;
-using ::testing::Lt;
-...
-  EXPECT_CALL(foo, Blah(_, _, _))
-      .With(AllOf(Args<0, 1>(Lt()), Args<1, 2>(Lt())));
-```
-
-says that `Blah()` will be called with arguments `x`, `y`, and `z` where
-`x < y < z`.
-
-As a convenience and example, Google Mock provides some matchers for
-2-tuples, including the `Lt()` matcher above. See the [CheatSheet](CheatSheet.md) for
-the complete list.
-
-Note that if you want to pass the arguments to a predicate of your own
-(e.g. `.With(Args<0, 1>(Truly(&MyPredicate)))`), that predicate MUST be
-written to take a `::testing::tuple` as its argument; Google Mock will pass the `n` selected arguments as _one_ single tuple to the predicate.
-
-## Using Matchers as Predicates ##
-
-Have you noticed that a matcher is just a fancy predicate that also
-knows how to describe itself? Many existing algorithms take predicates
-as arguments (e.g. those defined in STL's `<algorithm>` header), and
-it would be a shame if Google Mock matchers are not allowed to
-participate.
-
-Luckily, you can use a matcher where a unary predicate functor is
-expected by wrapping it inside the `Matches()` function. For example,
-
-```
-#include <algorithm>
-#include <vector>
-
-std::vector<int> v;
-...
-// How many elements in v are >= 10?
-const int count = count_if(v.begin(), v.end(), Matches(Ge(10)));
-```
-
-Since you can build complex matchers from simpler ones easily using
-Google Mock, this gives you a way to conveniently construct composite
-predicates (doing the same using STL's `<functional>` header is just
-painful). For example, here's a predicate that's satisfied by any
-number that is >= 0, <= 100, and != 50:
-
-```
-Matches(AllOf(Ge(0), Le(100), Ne(50)))
-```
-
-## Using Matchers in Google Test Assertions ##
-
-Since matchers are basically predicates that also know how to describe
-themselves, there is a way to take advantage of them in
-[Google Test](../../googletest/) assertions. It's
-called `ASSERT_THAT` and `EXPECT_THAT`:
-
-```
-  ASSERT_THAT(value, matcher);  // Asserts that value matches matcher.
-  EXPECT_THAT(value, matcher);  // The non-fatal version.
-```
-
-For example, in a Google Test test you can write:
-
-```
-#include "gmock/gmock.h"
-
-using ::testing::AllOf;
-using ::testing::Ge;
-using ::testing::Le;
-using ::testing::MatchesRegex;
-using ::testing::StartsWith;
-...
-
-  EXPECT_THAT(Foo(), StartsWith("Hello"));
-  EXPECT_THAT(Bar(), MatchesRegex("Line \\d+"));
-  ASSERT_THAT(Baz(), AllOf(Ge(5), Le(10)));
-```
-
-which (as you can probably guess) executes `Foo()`, `Bar()`, and
-`Baz()`, and verifies that:
-
-  * `Foo()` returns a string that starts with `"Hello"`.
-  * `Bar()` returns a string that matches regular expression `"Line \\d+"`.
-  * `Baz()` returns a number in the range [5, 10].
-
-The nice thing about these macros is that _they read like
-English_. They generate informative messages too. For example, if the
-first `EXPECT_THAT()` above fails, the message will be something like:
-
-```
-Value of: Foo()
-  Actual: "Hi, world!"
-Expected: starts with "Hello"
-```
-
-**Credit:** The idea of `(ASSERT|EXPECT)_THAT` was stolen from the
-[Hamcrest](https://github.com/hamcrest/) project, which adds
-`assertThat()` to JUnit.
-
-## Using Predicates as Matchers ##
-
-Google Mock provides a built-in set of matchers. In case you find them
-lacking, you can use an arbitray unary predicate function or functor
-as a matcher - as long as the predicate accepts a value of the type
-you want. You do this by wrapping the predicate inside the `Truly()`
-function, for example:
-
-```
-using ::testing::Truly;
-
-int IsEven(int n) { return (n % 2) == 0 ? 1 : 0; }
-...
-
-  // Bar() must be called with an even number.
-  EXPECT_CALL(foo, Bar(Truly(IsEven)));
-```
-
-Note that the predicate function / functor doesn't have to return
-`bool`. It works as long as the return value can be used as the
-condition in statement `if (condition) ...`.
-
-## Matching Arguments that Are Not Copyable ##
-
-When you do an `EXPECT_CALL(mock_obj, Foo(bar))`, Google Mock saves
-away a copy of `bar`. When `Foo()` is called later, Google Mock
-compares the argument to `Foo()` with the saved copy of `bar`. This
-way, you don't need to worry about `bar` being modified or destroyed
-after the `EXPECT_CALL()` is executed. The same is true when you use
-matchers like `Eq(bar)`, `Le(bar)`, and so on.
-
-But what if `bar` cannot be copied (i.e. has no copy constructor)? You
-could define your own matcher function and use it with `Truly()`, as
-the previous couple of recipes have shown. Or, you may be able to get
-away from it if you can guarantee that `bar` won't be changed after
-the `EXPECT_CALL()` is executed. Just tell Google Mock that it should
-save a reference to `bar`, instead of a copy of it. Here's how:
-
-```
-using ::testing::Eq;
-using ::testing::ByRef;
-using ::testing::Lt;
-...
-  // Expects that Foo()'s argument == bar.
-  EXPECT_CALL(mock_obj, Foo(Eq(ByRef(bar))));
-
-  // Expects that Foo()'s argument < bar.
-  EXPECT_CALL(mock_obj, Foo(Lt(ByRef(bar))));
-```
-
-Remember: if you do this, don't change `bar` after the
-`EXPECT_CALL()`, or the result is undefined.
-
-## Validating a Member of an Object ##
-
-Often a mock function takes a reference to object as an argument. When
-matching the argument, you may not want to compare the entire object
-against a fixed object, as that may be over-specification. Instead,
-you may need to validate a certain member variable or the result of a
-certain getter method of the object. You can do this with `Field()`
-and `Property()`. More specifically,
-
-```
-Field(&Foo::bar, m)
-```
-
-is a matcher that matches a `Foo` object whose `bar` member variable
-satisfies matcher `m`.
-
-```
-Property(&Foo::baz, m)
-```
-
-is a matcher that matches a `Foo` object whose `baz()` method returns
-a value that satisfies matcher `m`.
-
-For example:
-
-| Expression                   | Description                        |
-|:-----------------------------|:-----------------------------------|
-| `Field(&Foo::number, Ge(3))` | Matches `x` where `x.number >= 3`. |
-| `Property(&Foo::name, StartsWith("John "))` | Matches `x` where `x.name()` starts with `"John "`. |
-
-Note that in `Property(&Foo::baz, ...)`, method `baz()` must take no
-argument and be declared as `const`.
-
-BTW, `Field()` and `Property()` can also match plain pointers to
-objects. For instance,
-
-```
-Field(&Foo::number, Ge(3))
-```
-
-matches a plain pointer `p` where `p->number >= 3`. If `p` is `NULL`,
-the match will always fail regardless of the inner matcher.
-
-What if you want to validate more than one members at the same time?
-Remember that there is `AllOf()`.
-
-## Validating the Value Pointed to by a Pointer Argument ##
-
-C++ functions often take pointers as arguments. You can use matchers
-like `IsNull()`, `NotNull()`, and other comparison matchers to match a
-pointer, but what if you want to make sure the value _pointed to_ by
-the pointer, instead of the pointer itself, has a certain property?
-Well, you can use the `Pointee(m)` matcher.
-
-`Pointee(m)` matches a pointer iff `m` matches the value the pointer
-points to. For example:
-
-```
-using ::testing::Ge;
-using ::testing::Pointee;
-...
-  EXPECT_CALL(foo, Bar(Pointee(Ge(3))));
-```
-
-expects `foo.Bar()` to be called with a pointer that points to a value
-greater than or equal to 3.
-
-One nice thing about `Pointee()` is that it treats a `NULL` pointer as
-a match failure, so you can write `Pointee(m)` instead of
-
-```
-  AllOf(NotNull(), Pointee(m))
-```
-
-without worrying that a `NULL` pointer will crash your test.
-
-Also, did we tell you that `Pointee()` works with both raw pointers
-**and** smart pointers (`linked_ptr`, `shared_ptr`, `scoped_ptr`, and
-etc)?
-
-What if you have a pointer to pointer? You guessed it - you can use
-nested `Pointee()` to probe deeper inside the value. For example,
-`Pointee(Pointee(Lt(3)))` matches a pointer that points to a pointer
-that points to a number less than 3 (what a mouthful...).
-
-## Testing a Certain Property of an Object ##
-
-Sometimes you want to specify that an object argument has a certain
-property, but there is no existing matcher that does this. If you want
-good error messages, you should define a matcher. If you want to do it
-quick and dirty, you could get away with writing an ordinary function.
-
-Let's say you have a mock function that takes an object of type `Foo`,
-which has an `int bar()` method and an `int baz()` method, and you
-want to constrain that the argument's `bar()` value plus its `baz()`
-value is a given number. Here's how you can define a matcher to do it:
-
-```
-using ::testing::MatcherInterface;
-using ::testing::MatchResultListener;
-
-class BarPlusBazEqMatcher : public MatcherInterface<const Foo&> {
- public:
-  explicit BarPlusBazEqMatcher(int expected_sum)
-      : expected_sum_(expected_sum) {}
-
-  virtual bool MatchAndExplain(const Foo& foo,
-                               MatchResultListener* listener) const {
-    return (foo.bar() + foo.baz()) == expected_sum_;
-  }
-
-  virtual void DescribeTo(::std::ostream* os) const {
-    *os << "bar() + baz() equals " << expected_sum_;
-  }
-
-  virtual void DescribeNegationTo(::std::ostream* os) const {
-    *os << "bar() + baz() does not equal " << expected_sum_;
-  }
- private:
-  const int expected_sum_;
-};
-
-inline Matcher<const Foo&> BarPlusBazEq(int expected_sum) {
-  return MakeMatcher(new BarPlusBazEqMatcher(expected_sum));
-}
-
-...
-
-  EXPECT_CALL(..., DoThis(BarPlusBazEq(5)))...;
-```
-
-## Matching Containers ##
-
-Sometimes an STL container (e.g. list, vector, map, ...) is passed to
-a mock function and you may want to validate it. Since most STL
-containers support the `==` operator, you can write
-`Eq(expected_container)` or simply `expected_container` to match a
-container exactly.
-
-Sometimes, though, you may want to be more flexible (for example, the
-first element must be an exact match, but the second element can be
-any positive number, and so on). Also, containers used in tests often
-have a small number of elements, and having to define the expected
-container out-of-line is a bit of a hassle.
-
-You can use the `ElementsAre()` or `UnorderedElementsAre()` matcher in
-such cases:
-
-```
-using ::testing::_;
-using ::testing::ElementsAre;
-using ::testing::Gt;
-...
-
-  MOCK_METHOD1(Foo, void(const vector<int>& numbers));
-...
-
-  EXPECT_CALL(mock, Foo(ElementsAre(1, Gt(0), _, 5)));
-```
-
-The above matcher says that the container must have 4 elements, which
-must be 1, greater than 0, anything, and 5 respectively.
-
-If you instead write:
-
-```
-using ::testing::_;
-using ::testing::Gt;
-using ::testing::UnorderedElementsAre;
-...
-
-  MOCK_METHOD1(Foo, void(const vector<int>& numbers));
-...
-
-  EXPECT_CALL(mock, Foo(UnorderedElementsAre(1, Gt(0), _, 5)));
-```
-
-It means that the container must have 4 elements, which under some
-permutation must be 1, greater than 0, anything, and 5 respectively.
-
-`ElementsAre()` and `UnorderedElementsAre()` are overloaded to take 0
-to 10 arguments. If more are needed, you can place them in a C-style
-array and use `ElementsAreArray()` or `UnorderedElementsAreArray()`
-instead:
-
-```
-using ::testing::ElementsAreArray;
-...
-
-  // ElementsAreArray accepts an array of element values.
-  const int expected_vector1[] = { 1, 5, 2, 4, ... };
-  EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector1)));
-
-  // Or, an array of element matchers.
-  Matcher<int> expected_vector2 = { 1, Gt(2), _, 3, ... };
-  EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector2)));
-```
-
-In case the array needs to be dynamically created (and therefore the
-array size cannot be inferred by the compiler), you can give
-`ElementsAreArray()` an additional argument to specify the array size:
-
-```
-using ::testing::ElementsAreArray;
-...
-  int* const expected_vector3 = new int[count];
-  ... fill expected_vector3 with values ...
-  EXPECT_CALL(mock, Foo(ElementsAreArray(expected_vector3, count)));
-```
-
-**Tips:**
-
-  * `ElementsAre*()` can be used to match _any_ container that implements the STL iterator pattern (i.e. it has a `const_iterator` type and supports `begin()/end()`), not just the ones defined in STL. It will even work with container types yet to be written - as long as they follows the above pattern.
-  * You can use nested `ElementsAre*()` to match nested (multi-dimensional) containers.
-  * If the container is passed by pointer instead of by reference, just write `Pointee(ElementsAre*(...))`.
-  * The order of elements _matters_ for `ElementsAre*()`. Therefore don't use it with containers whose element order is undefined (e.g. `hash_map`).
-
-## Sharing Matchers ##
-
-Under the hood, a Google Mock matcher object consists of a pointer to
-a ref-counted implementation object. Copying matchers is allowed and
-very efficient, as only the pointer is copied. When the last matcher
-that references the implementation object dies, the implementation
-object will be deleted.
-
-Therefore, if you have some complex matcher that you want to use again
-and again, there is no need to build it every time. Just assign it to a
-matcher variable and use that variable repeatedly! For example,
-
-```
-  Matcher<int> in_range = AllOf(Gt(5), Le(10));
-  ... use in_range as a matcher in multiple EXPECT_CALLs ...
-```

-# Setting Expectations #
-
-## Knowing When to Expect ##
-
-`ON_CALL` is likely the single most under-utilized construct in Google Mock.
-
-There are basically two constructs for defining the behavior of a mock object: `ON_CALL` and `EXPECT_CALL`. The difference? `ON_CALL` defines what happens when a mock method is called, but _doesn't imply any expectation on the method being called._ `EXPECT_CALL` not only defines the behavior, but also sets an expectation that _the method will be called with the given arguments, for the given number of times_ (and _in the given order_ when you specify the order too).
-
-Since `EXPECT_CALL` does more, isn't it better than `ON_CALL`? Not really. Every `EXPECT_CALL` adds a constraint on the behavior of the code under test. Having more constraints than necessary is _baaad_ - even worse than not having enough constraints.
-
-This may be counter-intuitive. How could tests that verify more be worse than tests that verify less? Isn't verification the whole point of tests?
-
-The answer, lies in _what_ a test should verify. **A good test verifies the contract of the code.** If a test over-specifies, it doesn't leave enough freedom to the implementation. As a result, changing the implementation without breaking the contract (e.g. refactoring and optimization), which should be perfectly fine to do, can break such tests. Then you have to spend time fixing them, only to see them broken again the next time the implementation is changed.
-
-Keep in mind that one doesn't have to verify more than one property in one test. In fact, **it's a good style to verify only one thing in one test.** If you do that, a bug will likely break only one or two tests instead of dozens (which case would you rather debug?). If you are also in the habit of giving tests descriptive names that tell what they verify, you can often easily guess what's wrong just from the test log itself.
-
-So use `ON_CALL` by default, and only use `EXPECT_CALL` when you actually intend to verify that the call is made. For example, you may have a bunch of `ON_CALL`s in your test fixture to set the common mock behavior shared by all tests in the same group, and write (scarcely) different `EXPECT_CALL`s in different `TEST_F`s to verify different aspects of the code's behavior. Compared with the style where each `TEST` has many `EXPECT_CALL`s, this leads to tests that are more resilient to implementational changes (and thus less likely to require maintenance) and makes the intent of the tests more obvious (so they are easier to maintain when you do need to maintain them).
-
-If you are bothered by the "Uninteresting mock function call" message printed when a mock method without an `EXPECT_CALL` is called, you may use a `NiceMock` instead to suppress all such messages for the mock object, or suppress the message for specific methods by adding `EXPECT_CALL(...).Times(AnyNumber())`. DO NOT suppress it by blindly adding an `EXPECT_CALL(...)`, or you'll have a test that's a pain to maintain.
-
-## Ignoring Uninteresting Calls ##
-
-If you are not interested in how a mock method is called, just don't
-say anything about it. In this case, if the method is ever called,
-Google Mock will perform its default action to allow the test program
-to continue. If you are not happy with the default action taken by
-Google Mock, you can override it using `DefaultValue<T>::Set()`
-(described later in this document) or `ON_CALL()`.
-
-Please note that once you expressed interest in a particular mock
-method (via `EXPECT_CALL()`), all invocations to it must match some
-expectation. If this function is called but the arguments don't match
-any `EXPECT_CALL()` statement, it will be an error.
-
-## Disallowing Unexpected Calls ##
-
-If a mock method shouldn't be called at all, explicitly say so:
-
-```
-using ::testing::_;
-...
-  EXPECT_CALL(foo, Bar(_))
-      .Times(0);
-```
-
-If some calls to the method are allowed, but the rest are not, just
-list all the expected calls:
-
-```
-using ::testing::AnyNumber;
-using ::testing::Gt;
-...
-  EXPECT_CALL(foo, Bar(5));
-  EXPECT_CALL(foo, Bar(Gt(10)))
-      .Times(AnyNumber());
-```
-
-A call to `foo.Bar()` that doesn't match any of the `EXPECT_CALL()`
-statements will be an error.
-
-## Understanding Uninteresting vs Unexpected Calls ##
-
-_Uninteresting_ calls and _unexpected_ calls are different concepts in Google Mock. _Very_ different.
-
-A call `x.Y(...)` is **uninteresting** if there's _not even a single_ `EXPECT_CALL(x, Y(...))` set. In other words, the test isn't interested in the `x.Y()` method at all, as evident in that the test doesn't care to say anything about it.
-
-A call `x.Y(...)` is **unexpected** if there are some `EXPECT_CALL(x, Y(...))s` set, but none of them matches the call. Put another way, the test is interested in the `x.Y()` method (therefore it _explicitly_ sets some `EXPECT_CALL` to verify how it's called); however, the verification fails as the test doesn't expect this particular call to happen.
-
-**An unexpected call is always an error,** as the code under test doesn't behave the way the test expects it to behave.
-
-**By default, an uninteresting call is not an error,** as it violates no constraint specified by the test. (Google Mock's philosophy is that saying nothing means there is no constraint.) However, it leads to a warning, as it _might_ indicate a problem (e.g. the test author might have forgotten to specify a constraint).
-
-In Google Mock, `NiceMock` and `StrictMock` can be used to make a mock class "nice" or "strict". How does this affect uninteresting calls and unexpected calls?
-
-A **nice mock** suppresses uninteresting call warnings. It is less chatty than the default mock, but otherwise is the same. If a test fails with a default mock, it will also fail using a nice mock instead. And vice versa. Don't expect making a mock nice to change the test's result.
-
-A **strict mock** turns uninteresting call warnings into errors. So making a mock strict may change the test's result.
-
-Let's look at an example:
-
-```
-TEST(...) {
-  NiceMock<MockDomainRegistry> mock_registry;
-  EXPECT_CALL(mock_registry, GetDomainOwner("google.com"))
-          .WillRepeatedly(Return("Larry Page"));
-
-  // Use mock_registry in code under test.
-  ... &mock_registry ...
-}
-```
-
-The sole `EXPECT_CALL` here says that all calls to `GetDomainOwner()` must have `"google.com"` as the argument. If `GetDomainOwner("yahoo.com")` is called, it will be an unexpected call, and thus an error. Having a nice mock doesn't change the severity of an unexpected call.
-
-So how do we tell Google Mock that `GetDomainOwner()` can be called with some other arguments as well? The standard technique is to add a "catch all" `EXPECT_CALL`:
-
-```
-  EXPECT_CALL(mock_registry, GetDomainOwner(_))
-        .Times(AnyNumber());  // catches all other calls to this method.
-  EXPECT_CALL(mock_registry, GetDomainOwner("google.com"))
-        .WillRepeatedly(Return("Larry Page"));
-```
-
-Remember that `_` is the wildcard matcher that matches anything. With this, if `GetDomainOwner("google.com")` is called, it will do what the second `EXPECT_CALL` says; if it is called with a different argument, it will do what the first `EXPECT_CALL` says.
-
-Note that the order of the two `EXPECT_CALLs` is important, as a newer `EXPECT_CALL` takes precedence over an older one.
-
-For more on uninteresting calls, nice mocks, and strict mocks, read ["The Nice, the Strict, and the Naggy"](#the-nice-the-strict-and-the-naggy).
-
-## Expecting Ordered Calls ##
-
-Although an `EXPECT_CALL()` statement defined earlier takes precedence
-when Google Mock tries to match a function call with an expectation,
-by default calls don't have to happen in the order `EXPECT_CALL()`
-statements are written. For example, if the arguments match the
-matchers in the third `EXPECT_CALL()`, but not those in the first two,
-then the third expectation will be used.
-
-If you would rather have all calls occur in the order of the
-expectations, put the `EXPECT_CALL()` statements in a block where you
-define a variable of type `InSequence`:
-
-```
-  using ::testing::_;
-  using ::testing::InSequence;
-
-  {
-    InSequence s;
-
-    EXPECT_CALL(foo, DoThis(5));
-    EXPECT_CALL(bar, DoThat(_))
-        .Times(2);
-    EXPECT_CALL(foo, DoThis(6));
-  }
-```
-
-In this example, we expect a call to `foo.DoThis(5)`, followed by two
-calls to `bar.DoThat()` where the argument can be anything, which are
-in turn followed by a call to `foo.DoThis(6)`. If a call occurred
-out-of-order, Google Mock will report an error.
-
-## Expecting Partially Ordered Calls ##
-
-Sometimes requiring everything to occur in a predetermined order can
-lead to brittle tests. For example, we may care about `A` occurring
-before both `B` and `C`, but aren't interested in the relative order
-of `B` and `C`. In this case, the test should reflect our real intent,
-instead of being overly constraining.
-
-Google Mock allows you to impose an arbitrary DAG (directed acyclic
-graph) on the calls. One way to express the DAG is to use the
-[After](CheatSheet.md#the-after-clause) clause of `EXPECT_CALL`.
-
-Another way is via the `InSequence()` clause (not the same as the
-`InSequence` class), which we borrowed from jMock 2. It's less
-flexible than `After()`, but more convenient when you have long chains
-of sequential calls, as it doesn't require you to come up with
-different names for the expectations in the chains.  Here's how it
-works:
-
-If we view `EXPECT_CALL()` statements as nodes in a graph, and add an
-edge from node A to node B wherever A must occur before B, we can get
-a DAG. We use the term "sequence" to mean a directed path in this
-DAG. Now, if we decompose the DAG into sequences, we just need to know
-which sequences each `EXPECT_CALL()` belongs to in order to be able to
-reconstruct the original DAG.
-
-So, to specify the partial order on the expectations we need to do two
-things: first to define some `Sequence` objects, and then for each
-`EXPECT_CALL()` say which `Sequence` objects it is part
-of. Expectations in the same sequence must occur in the order they are
-written. For example,
-
-```
-  using ::testing::Sequence;
-
-  Sequence s1, s2;
-
-  EXPECT_CALL(foo, A())
-      .InSequence(s1, s2);
-  EXPECT_CALL(bar, B())
-      .InSequence(s1);
-  EXPECT_CALL(bar, C())
-      .InSequence(s2);
-  EXPECT_CALL(foo, D())
-      .InSequence(s2);
-```
-
-specifies the following DAG (where `s1` is `A -> B`, and `s2` is `A ->
-C -> D`):
-
-```
-       +---> B
-       |
-  A ---|
-       |
-       +---> C ---> D
-```
-
-This means that A must occur before B and C, and C must occur before
-D. There's no restriction about the order other than these.
-
-## Controlling When an Expectation Retires ##
-
-When a mock method is called, Google Mock only consider expectations
-that are still active. An expectation is active when created, and
-becomes inactive (aka _retires_) when a call that has to occur later
-has occurred. For example, in
-
-```
-  using ::testing::_;
-  using ::testing::Sequence;
-
-  Sequence s1, s2;
-
-  EXPECT_CALL(log, Log(WARNING, _, "File too large."))     // #1
-      .Times(AnyNumber())
-      .InSequence(s1, s2);
-  EXPECT_CALL(log, Log(WARNING, _, "Data set is empty."))  // #2
-      .InSequence(s1);
-  EXPECT_CALL(log, Log(WARNING, _, "User not found."))     // #3
-      .InSequence(s2);
-```
-
-as soon as either #2 or #3 is matched, #1 will retire. If a warning
-`"File too large."` is logged after this, it will be an error.
-
-Note that an expectation doesn't retire automatically when it's
-saturated. For example,
-
-```
-using ::testing::_;
-...
-  EXPECT_CALL(log, Log(WARNING, _, _));                  // #1
-  EXPECT_CALL(log, Log(WARNING, _, "File too large."));  // #2
-```
-
-says that there will be exactly one warning with the message `"File
-too large."`. If the second warning contains this message too, #2 will
-match again and result in an upper-bound-violated error.
-
-If this is not what you want, you can ask an expectation to retire as
-soon as it becomes saturated:
-
-```
-using ::testing::_;
-...
-  EXPECT_CALL(log, Log(WARNING, _, _));                 // #1
-  EXPECT_CALL(log, Log(WARNING, _, "File too large."))  // #2
-      .RetiresOnSaturation();
-```
-
-Here #2 can be used only once, so if you have two warnings with the
-message `"File too large."`, the first will match #2 and the second
-will match #1 - there will be no error.
-
-# Using Actions #
-
-## Returning References from Mock Methods ##
-
-If a mock function's return type is a reference, you need to use
-`ReturnRef()` instead of `Return()` to return a result:
-
-```
-using ::testing::ReturnRef;
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD0(GetBar, Bar&());
-};
-...
-
-  MockFoo foo;
-  Bar bar;
-  EXPECT_CALL(foo, GetBar())
-      .WillOnce(ReturnRef(bar));
-```
-
-## Returning Live Values from Mock Methods ##
-
-The `Return(x)` action saves a copy of `x` when the action is
-_created_, and always returns the same value whenever it's
-executed. Sometimes you may want to instead return the _live_ value of
-`x` (i.e. its value at the time when the action is _executed_.).
-
-If the mock function's return type is a reference, you can do it using
-`ReturnRef(x)`, as shown in the previous recipe ("Returning References
-from Mock Methods"). However, Google Mock doesn't let you use
-`ReturnRef()` in a mock function whose return type is not a reference,
-as doing that usually indicates a user error. So, what shall you do?
-
-You may be tempted to try `ByRef()`:
-
-```
-using testing::ByRef;
-using testing::Return;
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD0(GetValue, int());
-};
-...
-  int x = 0;
-  MockFoo foo;
-  EXPECT_CALL(foo, GetValue())
-      .WillRepeatedly(Return(ByRef(x)));
-  x = 42;
-  EXPECT_EQ(42, foo.GetValue());
-```
-
-Unfortunately, it doesn't work here. The above code will fail with error:
-
-```
-Value of: foo.GetValue()
-  Actual: 0
-Expected: 42
-```
-
-The reason is that `Return(value)` converts `value` to the actual
-return type of the mock function at the time when the action is
-_created_, not when it is _executed_. (This behavior was chosen for
-the action to be safe when `value` is a proxy object that references
-some temporary objects.) As a result, `ByRef(x)` is converted to an
-`int` value (instead of a `const int&`) when the expectation is set,
-and `Return(ByRef(x))` will always return 0.
-
-`ReturnPointee(pointer)` was provided to solve this problem
-specifically. It returns the value pointed to by `pointer` at the time
-the action is _executed_:
-
-```
-using testing::ReturnPointee;
-...
-  int x = 0;
-  MockFoo foo;
-  EXPECT_CALL(foo, GetValue())
-      .WillRepeatedly(ReturnPointee(&x));  // Note the & here.
-  x = 42;
-  EXPECT_EQ(42, foo.GetValue());  // This will succeed now.
-```
-
-## Combining Actions ##
-
-Want to do more than one thing when a function is called? That's
-fine. `DoAll()` allow you to do sequence of actions every time. Only
-the return value of the last action in the sequence will be used.
-
-```
-using ::testing::DoAll;
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD1(Bar, bool(int n));
-};
-...
-
-  EXPECT_CALL(foo, Bar(_))
-      .WillOnce(DoAll(action_1,
-                      action_2,
-                      ...
-                      action_n));
-```
-
-## Mocking Side Effects ##
-
-Sometimes a method exhibits its effect not via returning a value but
-via side effects. For example, it may change some global state or
-modify an output argument. To mock side effects, in general you can
-define your own action by implementing `::testing::ActionInterface`.
-
-If all you need to do is to change an output argument, the built-in
-`SetArgPointee()` action is convenient:
-
-```
-using ::testing::SetArgPointee;
-
-class MockMutator : public Mutator {
- public:
-  MOCK_METHOD2(Mutate, void(bool mutate, int* value));
-  ...
-};
-...
-
-  MockMutator mutator;
-  EXPECT_CALL(mutator, Mutate(true, _))
-      .WillOnce(SetArgPointee<1>(5));
-```
-
-In this example, when `mutator.Mutate()` is called, we will assign 5
-to the `int` variable pointed to by argument #1
-(0-based).
-
-`SetArgPointee()` conveniently makes an internal copy of the
-value you pass to it, removing the need to keep the value in scope and
-alive. The implication however is that the value must have a copy
-constructor and assignment operator.
-
-If the mock method also needs to return a value as well, you can chain
-`SetArgPointee()` with `Return()` using `DoAll()`:
-
-```
-using ::testing::_;
-using ::testing::Return;
-using ::testing::SetArgPointee;
-
-class MockMutator : public Mutator {
- public:
-  ...
-  MOCK_METHOD1(MutateInt, bool(int* value));
-};
-...
-
-  MockMutator mutator;
-  EXPECT_CALL(mutator, MutateInt(_))
-      .WillOnce(DoAll(SetArgPointee<0>(5),
-                      Return(true)));
-```
-
-If the output argument is an array, use the
-`SetArrayArgument<N>(first, last)` action instead. It copies the
-elements in source range `[first, last)` to the array pointed to by
-the `N`-th (0-based) argument:
-
-```
-using ::testing::NotNull;
-using ::testing::SetArrayArgument;
-
-class MockArrayMutator : public ArrayMutator {
- public:
-  MOCK_METHOD2(Mutate, void(int* values, int num_values));
-  ...
-};
-...
-
-  MockArrayMutator mutator;
-  int values[5] = { 1, 2, 3, 4, 5 };
-  EXPECT_CALL(mutator, Mutate(NotNull(), 5))
-      .WillOnce(SetArrayArgument<0>(values, values + 5));
-```
-
-This also works when the argument is an output iterator:
-
-```
-using ::testing::_;
-using ::testing::SetArrayArgument;
-
-class MockRolodex : public Rolodex {
- public:
-  MOCK_METHOD1(GetNames, void(std::back_insert_iterator<vector<string> >));
-  ...
-};
-...
-
-  MockRolodex rolodex;
-  vector<string> names;
-  names.push_back("George");
-  names.push_back("John");
-  names.push_back("Thomas");
-  EXPECT_CALL(rolodex, GetNames(_))
-      .WillOnce(SetArrayArgument<0>(names.begin(), names.end()));
-```
-
-## Changing a Mock Object's Behavior Based on the State ##
-
-If you expect a call to change the behavior of a mock object, you can use `::testing::InSequence` to specify different behaviors before and after the call:
-
-```
-using ::testing::InSequence;
-using ::testing::Return;
-
-...
-  {
-    InSequence seq;
-    EXPECT_CALL(my_mock, IsDirty())
-        .WillRepeatedly(Return(true));
-    EXPECT_CALL(my_mock, Flush());
-    EXPECT_CALL(my_mock, IsDirty())
-        .WillRepeatedly(Return(false));
-  }
-  my_mock.FlushIfDirty();
-```
-
-This makes `my_mock.IsDirty()` return `true` before `my_mock.Flush()` is called and return `false` afterwards.
-
-If the behavior change is more complex, you can store the effects in a variable and make a mock method get its return value from that variable:
-
-```
-using ::testing::_;
-using ::testing::SaveArg;
-using ::testing::Return;
-
-ACTION_P(ReturnPointee, p) { return *p; }
-...
-  int previous_value = 0;
-  EXPECT_CALL(my_mock, GetPrevValue())
-      .WillRepeatedly(ReturnPointee(&previous_value));
-  EXPECT_CALL(my_mock, UpdateValue(_))
-      .WillRepeatedly(SaveArg<0>(&previous_value));
-  my_mock.DoSomethingToUpdateValue();
-```
-
-Here `my_mock.GetPrevValue()` will always return the argument of the last `UpdateValue()` call.
-
-## Setting the Default Value for a Return Type ##
-
-If a mock method's return type is a built-in C++ type or pointer, by
-default it will return 0 when invoked. Also, in C++ 11 and above, a mock
-method whose return type has a default constructor will return a default-constructed
-value by default.  You only need to specify an
-action if this default value doesn't work for you.
-
-Sometimes, you may want to change this default value, or you may want
-to specify a default value for types Google Mock doesn't know
-about. You can do this using the `::testing::DefaultValue` class
-template:
-
-```
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD0(CalculateBar, Bar());
-};
-...
-
-  Bar default_bar;
-  // Sets the default return value for type Bar.
-  DefaultValue<Bar>::Set(default_bar);
-
-  MockFoo foo;
-
-  // We don't need to specify an action here, as the default
-  // return value works for us.
-  EXPECT_CALL(foo, CalculateBar());
-
-  foo.CalculateBar();  // This should return default_bar.
-
-  // Unsets the default return value.
-  DefaultValue<Bar>::Clear();
-```
-
-Please note that changing the default value for a type can make you
-tests hard to understand. We recommend you to use this feature
-judiciously. For example, you may want to make sure the `Set()` and
-`Clear()` calls are right next to the code that uses your mock.
-
-## Setting the Default Actions for a Mock Method ##
-
-You've learned how to change the default value of a given
-type. However, this may be too coarse for your purpose: perhaps you
-have two mock methods with the same return type and you want them to
-have different behaviors. The `ON_CALL()` macro allows you to
-customize your mock's behavior at the method level:
-
-```
-using ::testing::_;
-using ::testing::AnyNumber;
-using ::testing::Gt;
-using ::testing::Return;
-...
-  ON_CALL(foo, Sign(_))
-      .WillByDefault(Return(-1));
-  ON_CALL(foo, Sign(0))
-      .WillByDefault(Return(0));
-  ON_CALL(foo, Sign(Gt(0)))
-      .WillByDefault(Return(1));
-
-  EXPECT_CALL(foo, Sign(_))
-      .Times(AnyNumber());
-
-  foo.Sign(5);   // This should return 1.
-  foo.Sign(-9);  // This should return -1.
-  foo.Sign(0);   // This should return 0.
-```
-
-As you may have guessed, when there are more than one `ON_CALL()`
-statements, the news order take precedence over the older ones. In
-other words, the **last** one that matches the function arguments will
-be used. This matching order allows you to set up the common behavior
-in a mock object's constructor or the test fixture's set-up phase and
-specialize the mock's behavior later.
-
-## Using Functions/Methods/Functors as Actions ##
-
-If the built-in actions don't suit you, you can easily use an existing
-function, method, or functor as an action:
-
-```
-using ::testing::_;
-using ::testing::Invoke;
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD2(Sum, int(int x, int y));
-  MOCK_METHOD1(ComplexJob, bool(int x));
-};
-
-int CalculateSum(int x, int y) { return x + y; }
-
-class Helper {
- public:
-  bool ComplexJob(int x);
-};
-...
-
-  MockFoo foo;
-  Helper helper;
-  EXPECT_CALL(foo, Sum(_, _))
-      .WillOnce(Invoke(CalculateSum));
-  EXPECT_CALL(foo, ComplexJob(_))
-      .WillOnce(Invoke(&helper, &Helper::ComplexJob));
-
-  foo.Sum(5, 6);       // Invokes CalculateSum(5, 6).
-  foo.ComplexJob(10);  // Invokes helper.ComplexJob(10);
-```
-
-The only requirement is that the type of the function, etc must be
-_compatible_ with the signature of the mock function, meaning that the
-latter's arguments can be implicitly converted to the corresponding
-arguments of the former, and the former's return type can be
-implicitly converted to that of the latter. So, you can invoke
-something whose type is _not_ exactly the same as the mock function,
-as long as it's safe to do so - nice, huh?
-
-## Invoking a Function/Method/Functor Without Arguments ##
-
-`Invoke()` is very useful for doing actions that are more complex. It
-passes the mock function's arguments to the function or functor being
-invoked such that the callee has the full context of the call to work
-with. If the invoked function is not interested in some or all of the
-arguments, it can simply ignore them.
-
-Yet, a common pattern is that a test author wants to invoke a function
-without the arguments of the mock function. `Invoke()` allows her to
-do that using a wrapper function that throws away the arguments before
-invoking an underlining nullary function. Needless to say, this can be
-tedious and obscures the intent of the test.
-
-`InvokeWithoutArgs()` solves this problem. It's like `Invoke()` except
-that it doesn't pass the mock function's arguments to the
-callee. Here's an example:
-
-```
-using ::testing::_;
-using ::testing::InvokeWithoutArgs;
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD1(ComplexJob, bool(int n));
-};
-
-bool Job1() { ... }
-...
-
-  MockFoo foo;
-  EXPECT_CALL(foo, ComplexJob(_))
-      .WillOnce(InvokeWithoutArgs(Job1));
-
-  foo.ComplexJob(10);  // Invokes Job1().
-```
-
-## Invoking an Argument of the Mock Function ##
-
-Sometimes a mock function will receive a function pointer or a functor
-(in other words, a "callable") as an argument, e.g.
-
-```
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD2(DoThis, bool(int n, bool (*fp)(int)));
-};
-```
-
-and you may want to invoke this callable argument:
-
-```
-using ::testing::_;
-...
-  MockFoo foo;
-  EXPECT_CALL(foo, DoThis(_, _))
-      .WillOnce(...);
-  // Will execute (*fp)(5), where fp is the
-  // second argument DoThis() receives.
-```
-
-Arghh, you need to refer to a mock function argument but your version
-of C++ has no lambdas, so you have to define your own action. :-(
-Or do you really?
-
-Well, Google Mock has an action to solve _exactly_ this problem:
-
-```
-  InvokeArgument<N>(arg_1, arg_2, ..., arg_m)
-```
-
-will invoke the `N`-th (0-based) argument the mock function receives,
-with `arg_1`, `arg_2`, ..., and `arg_m`. No matter if the argument is
-a function pointer or a functor, Google Mock handles them both.
-
-With that, you could write:
-
-```
-using ::testing::_;
-using ::testing::InvokeArgument;
-...
-  EXPECT_CALL(foo, DoThis(_, _))
-      .WillOnce(InvokeArgument<1>(5));
-  // Will execute (*fp)(5), where fp is the
-  // second argument DoThis() receives.
-```
-
-What if the callable takes an argument by reference? No problem - just
-wrap it inside `ByRef()`:
-
-```
-...
-  MOCK_METHOD1(Bar, bool(bool (*fp)(int, const Helper&)));
-...
-using ::testing::_;
-using ::testing::ByRef;
-using ::testing::InvokeArgument;
-...
-
-  MockFoo foo;
-  Helper helper;
-  ...
-  EXPECT_CALL(foo, Bar(_))
-      .WillOnce(InvokeArgument<0>(5, ByRef(helper)));
-  // ByRef(helper) guarantees that a reference to helper, not a copy of it,
-  // will be passed to the callable.
-```
-
-What if the callable takes an argument by reference and we do **not**
-wrap the argument in `ByRef()`? Then `InvokeArgument()` will _make a
-copy_ of the argument, and pass a _reference to the copy_, instead of
-a reference to the original value, to the callable. This is especially
-handy when the argument is a temporary value:
-
-```
-...
-  MOCK_METHOD1(DoThat, bool(bool (*f)(const double& x, const string& s)));
-...
-using ::testing::_;
-using ::testing::InvokeArgument;
-...
-
-  MockFoo foo;
-  ...
-  EXPECT_CALL(foo, DoThat(_))
-      .WillOnce(InvokeArgument<0>(5.0, string("Hi")));
-  // Will execute (*f)(5.0, string("Hi")), where f is the function pointer
-  // DoThat() receives.  Note that the values 5.0 and string("Hi") are
-  // temporary and dead once the EXPECT_CALL() statement finishes.  Yet
-  // it's fine to perform this action later, since a copy of the values
-  // are kept inside the InvokeArgument action.
-```
-
-## Ignoring an Action's Result ##
-
-Sometimes you have an action that returns _something_, but you need an
-action that returns `void` (perhaps you want to use it in a mock
-function that returns `void`, or perhaps it needs to be used in
-`DoAll()` and it's not the last in the list). `IgnoreResult()` lets
-you do that. For example:
-
-```
-using ::testing::_;
-using ::testing::Invoke;
-using ::testing::Return;
-
-int Process(const MyData& data);
-string DoSomething();
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD1(Abc, void(const MyData& data));
-  MOCK_METHOD0(Xyz, bool());
-};
-...
-
-  MockFoo foo;
-  EXPECT_CALL(foo, Abc(_))
-  // .WillOnce(Invoke(Process));
-  // The above line won't compile as Process() returns int but Abc() needs
-  // to return void.
-      .WillOnce(IgnoreResult(Invoke(Process)));
-
-  EXPECT_CALL(foo, Xyz())
-      .WillOnce(DoAll(IgnoreResult(Invoke(DoSomething)),
-      // Ignores the string DoSomething() returns.
-                      Return(true)));
-```
-
-Note that you **cannot** use `IgnoreResult()` on an action that already
-returns `void`. Doing so will lead to ugly compiler errors.
-
-## Selecting an Action's Arguments ##
-
-Say you have a mock function `Foo()` that takes seven arguments, and
-you have a custom action that you want to invoke when `Foo()` is
-called. Trouble is, the custom action only wants three arguments:
-
-```
-using ::testing::_;
-using ::testing::Invoke;
-...
-  MOCK_METHOD7(Foo, bool(bool visible, const string& name, int x, int y,
-                         const map<pair<int, int>, double>& weight,
-                         double min_weight, double max_wight));
-...
-
-bool IsVisibleInQuadrant1(bool visible, int x, int y) {
-  return visible && x >= 0 && y >= 0;
-}
-...
-
-  EXPECT_CALL(mock, Foo(_, _, _, _, _, _, _))
-      .WillOnce(Invoke(IsVisibleInQuadrant1));  // Uh, won't compile. :-(
-```
-
-To please the compiler God, you can to define an "adaptor" that has
-the same signature as `Foo()` and calls the custom action with the
-right arguments:
-
-```
-using ::testing::_;
-using ::testing::Invoke;
-
-bool MyIsVisibleInQuadrant1(bool visible, const string& name, int x, int y,
-                            const map<pair<int, int>, double>& weight,
-                            double min_weight, double max_wight) {
-  return IsVisibleInQuadrant1(visible, x, y);
-}
-...
-
-  EXPECT_CALL(mock, Foo(_, _, _, _, _, _, _))
-      .WillOnce(Invoke(MyIsVisibleInQuadrant1));  // Now it works.
-```
-
-But isn't this awkward?
-
-Google Mock provides a generic _action adaptor_, so you can spend your
-time minding more important business than writing your own
-adaptors. Here's the syntax:
-
-```
-  WithArgs<N1, N2, ..., Nk>(action)
-```
-
-creates an action that passes the arguments of the mock function at
-the given indices (0-based) to the inner `action` and performs
-it. Using `WithArgs`, our original example can be written as:
-
-```
-using ::testing::_;
-using ::testing::Invoke;
-using ::testing::WithArgs;
-...
-  EXPECT_CALL(mock, Foo(_, _, _, _, _, _, _))
-      .WillOnce(WithArgs<0, 2, 3>(Invoke(IsVisibleInQuadrant1)));
-      // No need to define your own adaptor.
-```
-
-For better readability, Google Mock also gives you:
-
-  * `WithoutArgs(action)` when the inner `action` takes _no_ argument, and
-  * `WithArg<N>(action)` (no `s` after `Arg`) when the inner `action` takes _one_ argument.
-
-As you may have realized, `InvokeWithoutArgs(...)` is just syntactic
-sugar for `WithoutArgs(Invoke(...))`.
-
-Here are more tips:
-
-  * The inner action used in `WithArgs` and friends does not have to be `Invoke()` -- it can be anything.
-  * You can repeat an argument in the argument list if necessary, e.g. `WithArgs<2, 3, 3, 5>(...)`.
-  * You can change the order of the arguments, e.g. `WithArgs<3, 2, 1>(...)`.
-  * The types of the selected arguments do _not_ have to match the signature of the inner action exactly. It works as long as they can be implicitly converted to the corresponding arguments of the inner action. For example, if the 4-th argument of the mock function is an `int` and `my_action` takes a `double`, `WithArg<4>(my_action)` will work.
-
-## Ignoring Arguments in Action Functions ##
-
-The selecting-an-action's-arguments recipe showed us one way to make a
-mock function and an action with incompatible argument lists fit
-together. The downside is that wrapping the action in
-`WithArgs<...>()` can get tedious for people writing the tests.
-
-If you are defining a function, method, or functor to be used with
-`Invoke*()`, and you are not interested in some of its arguments, an
-alternative to `WithArgs` is to declare the uninteresting arguments as
-`Unused`. This makes the definition less cluttered and less fragile in
-case the types of the uninteresting arguments change. It could also
-increase the chance the action function can be reused. For example,
-given
-
-```
-  MOCK_METHOD3(Foo, double(const string& label, double x, double y));
-  MOCK_METHOD3(Bar, double(int index, double x, double y));
-```
-
-instead of
-
-```
-using ::testing::_;
-using ::testing::Invoke;
-
-double DistanceToOriginWithLabel(const string& label, double x, double y) {
-  return sqrt(x*x + y*y);
-}
-
-double DistanceToOriginWithIndex(int index, double x, double y) {
-  return sqrt(x*x + y*y);
-}
-...
-
-  EXEPCT_CALL(mock, Foo("abc", _, _))
-      .WillOnce(Invoke(DistanceToOriginWithLabel));
-  EXEPCT_CALL(mock, Bar(5, _, _))
-      .WillOnce(Invoke(DistanceToOriginWithIndex));
-```
-
-you could write
-
-```
-using ::testing::_;
-using ::testing::Invoke;
-using ::testing::Unused;
-
-double DistanceToOrigin(Unused, double x, double y) {
-  return sqrt(x*x + y*y);
-}
-...
-
-  EXEPCT_CALL(mock, Foo("abc", _, _))
-      .WillOnce(Invoke(DistanceToOrigin));
-  EXEPCT_CALL(mock, Bar(5, _, _))
-      .WillOnce(Invoke(DistanceToOrigin));
-```
-
-## Sharing Actions ##
-
-Just like matchers, a Google Mock action object consists of a pointer
-to a ref-counted implementation object. Therefore copying actions is
-also allowed and very efficient. When the last action that references
-the implementation object dies, the implementation object will be
-deleted.
-
-If you have some complex action that you want to use again and again,
-you may not have to build it from scratch every time. If the action
-doesn't have an internal state (i.e. if it always does the same thing
-no matter how many times it has been called), you can assign it to an
-action variable and use that variable repeatedly. For example:
-
-```
-  Action<bool(int*)> set_flag = DoAll(SetArgPointee<0>(5),
-                                      Return(true));
-  ... use set_flag in .WillOnce() and .WillRepeatedly() ...
-```
-
-However, if the action has its own state, you may be surprised if you
-share the action object. Suppose you have an action factory
-`IncrementCounter(init)` which creates an action that increments and
-returns a counter whose initial value is `init`, using two actions
-created from the same expression and using a shared action will
-exihibit different behaviors. Example:
-
-```
-  EXPECT_CALL(foo, DoThis())
-      .WillRepeatedly(IncrementCounter(0));
-  EXPECT_CALL(foo, DoThat())
-      .WillRepeatedly(IncrementCounter(0));
-  foo.DoThis();  // Returns 1.
-  foo.DoThis();  // Returns 2.
-  foo.DoThat();  // Returns 1 - Blah() uses a different
-                 // counter than Bar()'s.
-```
-
-versus
-
-```
-  Action<int()> increment = IncrementCounter(0);
-
-  EXPECT_CALL(foo, DoThis())
-      .WillRepeatedly(increment);
-  EXPECT_CALL(foo, DoThat())
-      .WillRepeatedly(increment);
-  foo.DoThis();  // Returns 1.
-  foo.DoThis();  // Returns 2.
-  foo.DoThat();  // Returns 3 - the counter is shared.
-```

-# Misc Recipes on Using Google Mock #
-
-## Mocking Methods That Use Move-Only Types ##
-
-C++11 introduced *move-only types*. A move-only-typed value can be moved from
-one object to another, but cannot be copied. `std::unique_ptr<T>` is
-probably the most commonly used move-only type.
-
-Mocking a method that takes and/or returns move-only types presents some
-challenges, but nothing insurmountable. This recipe shows you how you can do it.
-Note that the support for move-only method arguments was only introduced to
-gMock in April 2017; in older code, you may find more complex
-[workarounds](#LegacyMoveOnly) for lack of this feature.
-
-Let’s say we are working on a fictional project that lets one post and share
-snippets called “buzzes”. Your code uses these types:
-
-```cpp
-enum class AccessLevel { kInternal, kPublic };
-
-class Buzz {
- public:
-  explicit Buzz(AccessLevel access) { ... }
-  ...
-};
-
-class Buzzer {
- public:
-  virtual ~Buzzer() {}
-  virtual std::unique_ptr<Buzz> MakeBuzz(StringPiece text) = 0;
-  virtual bool ShareBuzz(std::unique_ptr<Buzz> buzz, int64_t timestamp) = 0;
-  ...
-};
-```
-
-A `Buzz` object represents a snippet being posted. A class that implements the
-`Buzzer` interface is capable of creating and sharing `Buzz`es. Methods in
-`Buzzer` may return a `unique_ptr<Buzz>` or take a
-`unique_ptr<Buzz>`. Now we need to mock `Buzzer` in our tests.
-
-To mock a method that accepts or returns move-only types, you just use the
-familiar `MOCK_METHOD` syntax as usual:
-
-```cpp
-class MockBuzzer : public Buzzer {
- public:
-  MOCK_METHOD1(MakeBuzz, std::unique_ptr<Buzz>(StringPiece text));
-  MOCK_METHOD2(ShareBuzz, bool(std::unique_ptr<Buzz> buzz, int64_t timestamp));
-};
-```
-
-Now that we have the mock class defined, we can use it in tests. In the
-following code examples, we assume that we have defined a `MockBuzzer` object
-named `mock_buzzer_`:
-
-```cpp
-  MockBuzzer mock_buzzer_;
-```
-
-First let’s see how we can set expectations on the `MakeBuzz()` method, which
-returns a `unique_ptr<Buzz>`.
-
-As usual, if you set an expectation without an action (i.e. the `.WillOnce()` or
-`.WillRepeated()` clause), when that expectation fires, the default action for
-that method will be taken. Since `unique_ptr<>` has a default constructor
-that returns a null `unique_ptr`, that’s what you’ll get if you don’t specify an
-action:
-
-```cpp
-  // Use the default action.
-  EXPECT_CALL(mock_buzzer_, MakeBuzz("hello"));
-
-  // Triggers the previous EXPECT_CALL.
-  EXPECT_EQ(nullptr, mock_buzzer_.MakeBuzz("hello"));
-```
-
-If you are not happy with the default action, you can tweak it as usual; see
-[Setting Default Actions](#OnCall).
-
-If you just need to return a pre-defined move-only value, you can use the
-`Return(ByMove(...))` action:
-
-```cpp
-  // When this fires, the unique_ptr<> specified by ByMove(...) will
-  // be returned.
-  EXPECT_CALL(mock_buzzer_, MakeBuzz("world"))
-      .WillOnce(Return(ByMove(MakeUnique<Buzz>(AccessLevel::kInternal))));
-
-  EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("world"));
-```
-
-Note that `ByMove()` is essential here - if you drop it, the code won’t compile.
-
-Quiz time! What do you think will happen if a `Return(ByMove(...))` action is
-performed more than once (e.g. you write
-`.WillRepeatedly(Return(ByMove(...)));`)? Come think of it, after the first
-time the action runs, the source value will be consumed (since it’s a move-only
-value), so the next time around, there’s no value to move from -- you’ll get a
-run-time error that `Return(ByMove(...))` can only be run once.
-
-If you need your mock method to do more than just moving a pre-defined value,
-remember that you can always use a lambda or a callable object, which can do
-pretty much anything you want:
-
-```cpp
-  EXPECT_CALL(mock_buzzer_, MakeBuzz("x"))
-      .WillRepeatedly([](StringPiece text) {
-        return MakeUnique<Buzz>(AccessLevel::kInternal);
-      });
-
-  EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("x"));
-  EXPECT_NE(nullptr, mock_buzzer_.MakeBuzz("x"));
-```
-
-Every time this `EXPECT_CALL` fires, a new `unique_ptr<Buzz>` will be
-created and returned. You cannot do this with `Return(ByMove(...))`.
-
-That covers returning move-only values; but how do we work with methods
-accepting move-only arguments? The answer is that they work normally, although
-some actions will not compile when any of method's arguments are move-only. You
-can always use `Return`, or a [lambda or functor](#FunctionsAsActions):
-
-```cpp
-  using ::testing::Unused;
-
-  EXPECT_CALL(mock_buzzer_, ShareBuzz(NotNull(), _)) .WillOnce(Return(true));
-  EXPECT_TRUE(mock_buzzer_.ShareBuzz(MakeUnique<Buzz>(AccessLevel::kInternal)),
-              0);
-
-  EXPECT_CALL(mock_buzzer_, ShareBuzz(_, _)) .WillOnce(
-      [](std::unique_ptr<Buzz> buzz, Unused) { return buzz != nullptr; });
-  EXPECT_FALSE(mock_buzzer_.ShareBuzz(nullptr, 0));
-```
-
-Many built-in actions (`WithArgs`, `WithoutArgs`,`DeleteArg`, `SaveArg`, ...)
-could in principle support move-only arguments, but the support for this is not
-implemented yet. If this is blocking you, please file a bug.
-
-A few actions (e.g. `DoAll`) copy their arguments internally, so they can never
-work with non-copyable objects; you'll have to use functors instead.
-
-##### Legacy workarounds for move-only types {#LegacyMoveOnly}
-
-Support for move-only function arguments was only introduced to gMock in April
-2017. In older code, you may encounter the following workaround for the lack of
-this feature (it is no longer necessary - we're including it just for
-reference):
-
-```cpp
-class MockBuzzer : public Buzzer {
- public:
-  MOCK_METHOD2(DoShareBuzz, bool(Buzz* buzz, Time timestamp));
-  bool ShareBuzz(std::unique_ptr<Buzz> buzz, Time timestamp) override {
-    return DoShareBuzz(buzz.get(), timestamp);
-  }
-};
-```
-
-The trick is to delegate the `ShareBuzz()` method to a mock method (let’s call
-it `DoShareBuzz()`) that does not take move-only parameters. Then, instead of
-setting expectations on `ShareBuzz()`, you set them on the `DoShareBuzz()` mock
-method:
-
-```cpp
-  MockBuzzer mock_buzzer_;
-  EXPECT_CALL(mock_buzzer_, DoShareBuzz(NotNull(), _));
-
-  // When one calls ShareBuzz() on the MockBuzzer like this, the call is
-  // forwarded to DoShareBuzz(), which is mocked.  Therefore this statement
-  // will trigger the above EXPECT_CALL.
-  mock_buzzer_.ShareBuzz(MakeUnique<Buzz>(AccessLevel::kInternal), 0);
-```
-
-
-
-## Making the Compilation Faster ##
-
-Believe it or not, the _vast majority_ of the time spent on compiling
-a mock class is in generating its constructor and destructor, as they
-perform non-trivial tasks (e.g. verification of the
-expectations). What's more, mock methods with different signatures
-have different types and thus their constructors/destructors need to
-be generated by the compiler separately. As a result, if you mock many
-different types of methods, compiling your mock class can get really
-slow.
-
-If you are experiencing slow compilation, you can move the definition
-of your mock class' constructor and destructor out of the class body
-and into a `.cpp` file. This way, even if you `#include` your mock
-class in N files, the compiler only needs to generate its constructor
-and destructor once, resulting in a much faster compilation.
-
-Let's illustrate the idea using an example. Here's the definition of a
-mock class before applying this recipe:
-
-```
-// File mock_foo.h.
-...
-class MockFoo : public Foo {
- public:
-  // Since we don't declare the constructor or the destructor,
-  // the compiler will generate them in every translation unit
-  // where this mock class is used.
-
-  MOCK_METHOD0(DoThis, int());
-  MOCK_METHOD1(DoThat, bool(const char* str));
-  ... more mock methods ...
-};
-```
-
-After the change, it would look like:
-
-```
-// File mock_foo.h.
-...
-class MockFoo : public Foo {
- public:
-  // The constructor and destructor are declared, but not defined, here.
-  MockFoo();
-  virtual ~MockFoo();
-
-  MOCK_METHOD0(DoThis, int());
-  MOCK_METHOD1(DoThat, bool(const char* str));
-  ... more mock methods ...
-};
-```
-and
-```
-// File mock_foo.cpp.
-#include "path/to/mock_foo.h"
-
-// The definitions may appear trivial, but the functions actually do a
-// lot of things through the constructors/destructors of the member
-// variables used to implement the mock methods.
-MockFoo::MockFoo() {}
-MockFoo::~MockFoo() {}
-```
-
-## Forcing a Verification ##
-
-When it's being destroyed, your friendly mock object will automatically
-verify that all expectations on it have been satisfied, and will
-generate [Google Test](../../googletest/) failures
-if not. This is convenient as it leaves you with one less thing to
-worry about. That is, unless you are not sure if your mock object will
-be destroyed.
-
-How could it be that your mock object won't eventually be destroyed?
-Well, it might be created on the heap and owned by the code you are
-testing. Suppose there's a bug in that code and it doesn't delete the
-mock object properly - you could end up with a passing test when
-there's actually a bug.
-
-Using a heap checker is a good idea and can alleviate the concern, but
-its implementation may not be 100% reliable. So, sometimes you do want
-to _force_ Google Mock to verify a mock object before it is
-(hopefully) destructed. You can do this with
-`Mock::VerifyAndClearExpectations(&mock_object)`:
-
-```
-TEST(MyServerTest, ProcessesRequest) {
-  using ::testing::Mock;
-
-  MockFoo* const foo = new MockFoo;
-  EXPECT_CALL(*foo, ...)...;
-  // ... other expectations ...
-
-  // server now owns foo.
-  MyServer server(foo);
-  server.ProcessRequest(...);
-
-  // In case that server's destructor will forget to delete foo,
-  // this will verify the expectations anyway.
-  Mock::VerifyAndClearExpectations(foo);
-}  // server is destroyed when it goes out of scope here.
-```
-
-**Tip:** The `Mock::VerifyAndClearExpectations()` function returns a
-`bool` to indicate whether the verification was successful (`true` for
-yes), so you can wrap that function call inside a `ASSERT_TRUE()` if
-there is no point going further when the verification has failed.
-
-## Using Check Points ##
-
-Sometimes you may want to "reset" a mock object at various check
-points in your test: at each check point, you verify that all existing
-expectations on the mock object have been satisfied, and then you set
-some new expectations on it as if it's newly created. This allows you
-to work with a mock object in "phases" whose sizes are each
-manageable.
-
-One such scenario is that in your test's `SetUp()` function, you may
-want to put the object you are testing into a certain state, with the
-help from a mock object. Once in the desired state, you want to clear
-all expectations on the mock, such that in the `TEST_F` body you can
-set fresh expectations on it.
-
-As you may have figured out, the `Mock::VerifyAndClearExpectations()`
-function we saw in the previous recipe can help you here. Or, if you
-are using `ON_CALL()` to set default actions on the mock object and
-want to clear the default actions as well, use
-`Mock::VerifyAndClear(&mock_object)` instead. This function does what
-`Mock::VerifyAndClearExpectations(&mock_object)` does and returns the
-same `bool`, **plus** it clears the `ON_CALL()` statements on
-`mock_object` too.
-
-Another trick you can use to achieve the same effect is to put the
-expectations in sequences and insert calls to a dummy "check-point"
-function at specific places. Then you can verify that the mock
-function calls do happen at the right time. For example, if you are
-exercising code:
-
-```
-Foo(1);
-Foo(2);
-Foo(3);
-```
-
-and want to verify that `Foo(1)` and `Foo(3)` both invoke
-`mock.Bar("a")`, but `Foo(2)` doesn't invoke anything. You can write:
-
-```
-using ::testing::MockFunction;
-
-TEST(FooTest, InvokesBarCorrectly) {
-  MyMock mock;
-  // Class MockFunction<F> has exactly one mock method.  It is named
-  // Call() and has type F.
-  MockFunction<void(string check_point_name)> check;
-  {
-    InSequence s;
-
-    EXPECT_CALL(mock, Bar("a"));
-    EXPECT_CALL(check, Call("1"));
-    EXPECT_CALL(check, Call("2"));
-    EXPECT_CALL(mock, Bar("a"));
-  }
-  Foo(1);
-  check.Call("1");
-  Foo(2);
-  check.Call("2");
-  Foo(3);
-}
-```
-
-The expectation spec says that the first `Bar("a")` must happen before
-check point "1", the second `Bar("a")` must happen after check point "2",
-and nothing should happen between the two check points. The explicit
-check points make it easy to tell which `Bar("a")` is called by which
-call to `Foo()`.
-
-## Mocking Destructors ##
-
-Sometimes you want to make sure a mock object is destructed at the
-right time, e.g. after `bar->A()` is called but before `bar->B()` is
-called. We already know that you can specify constraints on the order
-of mock function calls, so all we need to do is to mock the destructor
-of the mock function.
-
-This sounds simple, except for one problem: a destructor is a special
-function with special syntax and special semantics, and the
-`MOCK_METHOD0` macro doesn't work for it:
-
-```
-  MOCK_METHOD0(~MockFoo, void());  // Won't compile!
-```
-
-The good news is that you can use a simple pattern to achieve the same
-effect. First, add a mock function `Die()` to your mock class and call
-it in the destructor, like this:
-
-```
-class MockFoo : public Foo {
-  ...
-  // Add the following two lines to the mock class.
-  MOCK_METHOD0(Die, void());
-  virtual ~MockFoo() { Die(); }
-};
-```
-
-(If the name `Die()` clashes with an existing symbol, choose another
-name.) Now, we have translated the problem of testing when a `MockFoo`
-object dies to testing when its `Die()` method is called:
-
-```
-  MockFoo* foo = new MockFoo;
-  MockBar* bar = new MockBar;
-  ...
-  {
-    InSequence s;
-
-    // Expects *foo to die after bar->A() and before bar->B().
-    EXPECT_CALL(*bar, A());
-    EXPECT_CALL(*foo, Die());
-    EXPECT_CALL(*bar, B());
-  }
-```
-
-And that's that.
-
-## Using Google Mock and Threads ##
-
-**IMPORTANT NOTE:** What we describe in this recipe is **ONLY** true on
-platforms where Google Mock is thread-safe. Currently these are only
-platforms that support the pthreads library (this includes Linux and Mac).
-To make it thread-safe on other platforms we only need to implement
-some synchronization operations in `"gtest/internal/gtest-port.h"`.
-
-In a **unit** test, it's best if you could isolate and test a piece of
-code in a single-threaded context. That avoids race conditions and
-dead locks, and makes debugging your test much easier.
-
-Yet many programs are multi-threaded, and sometimes to test something
-we need to pound on it from more than one thread. Google Mock works
-for this purpose too.
-
-Remember the steps for using a mock:
-
-  1. Create a mock object `foo`.
-  1. Set its default actions and expectations using `ON_CALL()` and `EXPECT_CALL()`.
-  1. The code under test calls methods of `foo`.
-  1. Optionally, verify and reset the mock.
-  1. Destroy the mock yourself, or let the code under test destroy it. The destructor will automatically verify it.
-
-If you follow the following simple rules, your mocks and threads can
-live happily together:
-
-  * Execute your _test code_ (as opposed to the code being tested) in _one_ thread. This makes your test easy to follow.
-  * Obviously, you can do step #1 without locking.
-  * When doing step #2 and #5, make sure no other thread is accessing `foo`. Obvious too, huh?
-  * #3 and #4 can be done either in one thread or in multiple threads - anyway you want. Google Mock takes care of the locking, so you don't have to do any - unless required by your test logic.
-
-If you violate the rules (for example, if you set expectations on a
-mock while another thread is calling its methods), you get undefined
-behavior. That's not fun, so don't do it.
-
-Google Mock guarantees that the action for a mock function is done in
-the same thread that called the mock function. For example, in
-
-```
-  EXPECT_CALL(mock, Foo(1))
-      .WillOnce(action1);
-  EXPECT_CALL(mock, Foo(2))
-      .WillOnce(action2);
-```
-
-if `Foo(1)` is called in thread 1 and `Foo(2)` is called in thread 2,
-Google Mock will execute `action1` in thread 1 and `action2` in thread
-2.
-
-Google Mock does _not_ impose a sequence on actions performed in
-different threads (doing so may create deadlocks as the actions may
-need to cooperate). This means that the execution of `action1` and
-`action2` in the above example _may_ interleave. If this is a problem,
-you should add proper synchronization logic to `action1` and `action2`
-to make the test thread-safe.
-
-
-Also, remember that `DefaultValue<T>` is a global resource that
-potentially affects _all_ living mock objects in your
-program. Naturally, you won't want to mess with it from multiple
-threads or when there still are mocks in action.
-
-## Controlling How Much Information Google Mock Prints ##
-
-When Google Mock sees something that has the potential of being an
-error (e.g. a mock function with no expectation is called, a.k.a. an
-uninteresting call, which is allowed but perhaps you forgot to
-explicitly ban the call), it prints some warning messages, including
-the arguments of the function and the return value. Hopefully this
-will remind you to take a look and see if there is indeed a problem.
-
-Sometimes you are confident that your tests are correct and may not
-appreciate such friendly messages. Some other times, you are debugging
-your tests or learning about the behavior of the code you are testing,
-and wish you could observe every mock call that happens (including
-argument values and the return value). Clearly, one size doesn't fit
-all.
-
-You can control how much Google Mock tells you using the
-`--gmock_verbose=LEVEL` command-line flag, where `LEVEL` is a string
-with three possible values:
-
-  * `info`: Google Mock will print all informational messages, warnings, and errors (most verbose). At this setting, Google Mock will also log any calls to the `ON_CALL/EXPECT_CALL` macros.
-  * `warning`: Google Mock will print both warnings and errors (less verbose). This is the default.
-  * `error`: Google Mock will print errors only (least verbose).
-
-Alternatively, you can adjust the value of that flag from within your
-tests like so:
-
-```
-  ::testing::FLAGS_gmock_verbose = "error";
-```
-
-Now, judiciously use the right flag to enable Google Mock serve you better!
-
-## Gaining Super Vision into Mock Calls ##
-
-You have a test using Google Mock. It fails: Google Mock tells you
-that some expectations aren't satisfied. However, you aren't sure why:
-Is there a typo somewhere in the matchers? Did you mess up the order
-of the `EXPECT_CALL`s? Or is the code under test doing something
-wrong?  How can you find out the cause?
-
-Won't it be nice if you have X-ray vision and can actually see the
-trace of all `EXPECT_CALL`s and mock method calls as they are made?
-For each call, would you like to see its actual argument values and
-which `EXPECT_CALL` Google Mock thinks it matches?
-
-You can unlock this power by running your test with the
-`--gmock_verbose=info` flag. For example, given the test program:
-
-```
-using testing::_;
-using testing::HasSubstr;
-using testing::Return;
-
-class MockFoo {
- public:
-  MOCK_METHOD2(F, void(const string& x, const string& y));
-};
-
-TEST(Foo, Bar) {
-  MockFoo mock;
-  EXPECT_CALL(mock, F(_, _)).WillRepeatedly(Return());
-  EXPECT_CALL(mock, F("a", "b"));
-  EXPECT_CALL(mock, F("c", HasSubstr("d")));
-
-  mock.F("a", "good");
-  mock.F("a", "b");
-}
-```
-
-if you run it with `--gmock_verbose=info`, you will see this output:
-
-```
-[ RUN      ] Foo.Bar
-
-foo_test.cc:14: EXPECT_CALL(mock, F(_, _)) invoked
-foo_test.cc:15: EXPECT_CALL(mock, F("a", "b")) invoked
-foo_test.cc:16: EXPECT_CALL(mock, F("c", HasSubstr("d"))) invoked
-foo_test.cc:14: Mock function call matches EXPECT_CALL(mock, F(_, _))...
-    Function call: F(@0x7fff7c8dad40"a", @0x7fff7c8dad10"good")
-foo_test.cc:15: Mock function call matches EXPECT_CALL(mock, F("a", "b"))...
-    Function call: F(@0x7fff7c8dada0"a", @0x7fff7c8dad70"b")
-foo_test.cc:16: Failure
-Actual function call count doesn't match EXPECT_CALL(mock, F("c", HasSubstr("d")))...
-         Expected: to be called once
-           Actual: never called - unsatisfied and active
-[  FAILED  ] Foo.Bar
-```
-
-Suppose the bug is that the `"c"` in the third `EXPECT_CALL` is a typo
-and should actually be `"a"`. With the above message, you should see
-that the actual `F("a", "good")` call is matched by the first
-`EXPECT_CALL`, not the third as you thought. From that it should be
-obvious that the third `EXPECT_CALL` is written wrong. Case solved.
-
-## Running Tests in Emacs ##
-
-If you build and run your tests in Emacs, the source file locations of
-Google Mock and [Google Test](../../googletest/)
-errors will be highlighted. Just press `<Enter>` on one of them and
-you'll be taken to the offending line. Or, you can just type `C-x ``
-to jump to the next error.
-
-To make it even easier, you can add the following lines to your
-`~/.emacs` file:
-
-```
-(global-set-key "\M-m"   'compile)  ; m is for make
-(global-set-key [M-down] 'next-error)
-(global-set-key [M-up]   '(lambda () (interactive) (next-error -1)))
-```
-
-Then you can type `M-m` to start a build, or `M-up`/`M-down` to move
-back and forth between errors.
-
-## Fusing Google Mock Source Files ##
-
-Google Mock's implementation consists of dozens of files (excluding
-its own tests).  Sometimes you may want them to be packaged up in
-fewer files instead, such that you can easily copy them to a new
-machine and start hacking there.  For this we provide an experimental
-Python script `fuse_gmock_files.py` in the `scripts/` directory
-(starting with release 1.2.0).  Assuming you have Python 2.4 or above
-installed on your machine, just go to that directory and run
-```
-python fuse_gmock_files.py OUTPUT_DIR
-```
-
-and you should see an `OUTPUT_DIR` directory being created with files
-`gtest/gtest.h`, `gmock/gmock.h`, and `gmock-gtest-all.cc` in it.
-These three files contain everything you need to use Google Mock (and
-Google Test).  Just copy them to anywhere you want and you are ready
-to write tests and use mocks.  You can use the
-[scrpts/test/Makefile](../scripts/test/Makefile) file as an example on how to compile your tests
-against them.
-
-# Extending Google Mock #
-
-## Writing New Matchers Quickly ##
-
-The `MATCHER*` family of macros can be used to define custom matchers
-easily.  The syntax:
-
-```
-MATCHER(name, description_string_expression) { statements; }
-```
-
-will define a matcher with the given name that executes the
-statements, which must return a `bool` to indicate if the match
-succeeds.  Inside the statements, you can refer to the value being
-matched by `arg`, and refer to its type by `arg_type`.
-
-The description string is a `string`-typed expression that documents
-what the matcher does, and is used to generate the failure message
-when the match fails.  It can (and should) reference the special
-`bool` variable `negation`, and should evaluate to the description of
-the matcher when `negation` is `false`, or that of the matcher's
-negation when `negation` is `true`.
-
-For convenience, we allow the description string to be empty (`""`),
-in which case Google Mock will use the sequence of words in the
-matcher name as the description.
-
-For example:
-```
-MATCHER(IsDivisibleBy7, "") { return (arg % 7) == 0; }
-```
-allows you to write
-```
-  // Expects mock_foo.Bar(n) to be called where n is divisible by 7.
-  EXPECT_CALL(mock_foo, Bar(IsDivisibleBy7()));
-```
-or,
-```
-using ::testing::Not;
-...
-  EXPECT_THAT(some_expression, IsDivisibleBy7());
-  EXPECT_THAT(some_other_expression, Not(IsDivisibleBy7()));
-```
-If the above assertions fail, they will print something like:
-```
-  Value of: some_expression
-  Expected: is divisible by 7
-    Actual: 27
-...
-  Value of: some_other_expression
-  Expected: not (is divisible by 7)
-    Actual: 21
-```
-where the descriptions `"is divisible by 7"` and `"not (is divisible
-by 7)"` are automatically calculated from the matcher name
-`IsDivisibleBy7`.
-
-As you may have noticed, the auto-generated descriptions (especially
-those for the negation) may not be so great. You can always override
-them with a string expression of your own:
-```
-MATCHER(IsDivisibleBy7, std::string(negation ? "isn't" : "is") +
-                        " divisible by 7") {
-  return (arg % 7) == 0;
-}
-```
-
-Optionally, you can stream additional information to a hidden argument
-named `result_listener` to explain the match result. For example, a
-better definition of `IsDivisibleBy7` is:
-```
-MATCHER(IsDivisibleBy7, "") {
-  if ((arg % 7) == 0)
-    return true;
-
-  *result_listener << "the remainder is " << (arg % 7);
-  return false;
-}
-```
-
-With this definition, the above assertion will give a better message:
-```
-  Value of: some_expression
-  Expected: is divisible by 7
-    Actual: 27 (the remainder is 6)
-```
-
-You should let `MatchAndExplain()` print _any additional information_
-that can help a user understand the match result. Note that it should
-explain why the match succeeds in case of a success (unless it's
-obvious) - this is useful when the matcher is used inside
-`Not()`. There is no need to print the argument value itself, as
-Google Mock already prints it for you.
-
-**Notes:**
-
-  1. The type of the value being matched (`arg_type`) is determined by the context in which you use the matcher and is supplied to you by the compiler, so you don't need to worry about declaring it (nor can you).  This allows the matcher to be polymorphic.  For example, `IsDivisibleBy7()` can be used to match any type where the value of `(arg % 7) == 0` can be implicitly converted to a `bool`.  In the `Bar(IsDivisibleBy7())` example above, if method `Bar()` takes an `int`, `arg_type` will be `int`; if it takes an `unsigned long`, `arg_type` will be `unsigned long`; and so on.
-  1. Google Mock doesn't guarantee when or how many times a matcher will be invoked. Therefore the matcher logic must be _purely functional_ (i.e. it cannot have any side effect, and the result must not depend on anything other than the value being matched and the matcher parameters). This requirement must be satisfied no matter how you define the matcher (e.g. using one of the methods described in the following recipes). In particular, a matcher can never call a mock function, as that will affect the state of the mock object and Google Mock.
-
-## Writing New Parameterized Matchers Quickly ##
-
-Sometimes you'll want to define a matcher that has parameters.  For that you
-can use the macro:
-```
-MATCHER_P(name, param_name, description_string) { statements; }
-```
-where the description string can be either `""` or a string expression
-that references `negation` and `param_name`.
-
-For example:
-```
-MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
-```
-will allow you to write:
-```
-  EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
-```
-which may lead to this message (assuming `n` is 10):
-```
-  Value of: Blah("a")
-  Expected: has absolute value 10
-    Actual: -9
-```
-
-Note that both the matcher description and its parameter are
-printed, making the message human-friendly.
-
-In the matcher definition body, you can write `foo_type` to
-reference the type of a parameter named `foo`.  For example, in the
-body of `MATCHER_P(HasAbsoluteValue, value)` above, you can write
-`value_type` to refer to the type of `value`.
-
-Google Mock also provides `MATCHER_P2`, `MATCHER_P3`, ..., up to
-`MATCHER_P10` to support multi-parameter matchers:
-```
-MATCHER_Pk(name, param_1, ..., param_k, description_string) { statements; }
-```
-
-Please note that the custom description string is for a particular
-**instance** of the matcher, where the parameters have been bound to
-actual values.  Therefore usually you'll want the parameter values to
-be part of the description.  Google Mock lets you do that by
-referencing the matcher parameters in the description string
-expression.
-
-For example,
-```
-  using ::testing::PrintToString;
-  MATCHER_P2(InClosedRange, low, hi,
-             std::string(negation ? "isn't" : "is") + " in range [" +
-             PrintToString(low) + ", " + PrintToString(hi) + "]") {
-    return low <= arg && arg <= hi;
-  }
-  ...
-  EXPECT_THAT(3, InClosedRange(4, 6));
-```
-would generate a failure that contains the message:
-```
-  Expected: is in range [4, 6]
-```
-
-If you specify `""` as the description, the failure message will
-contain the sequence of words in the matcher name followed by the
-parameter values printed as a tuple.  For example,
-```
-  MATCHER_P2(InClosedRange, low, hi, "") { ... }
-  ...
-  EXPECT_THAT(3, InClosedRange(4, 6));
-```
-would generate a failure that contains the text:
-```
-  Expected: in closed range (4, 6)
-```
-
-For the purpose of typing, you can view
-```
-MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
-```
-as shorthand for
-```
-template <typename p1_type, ..., typename pk_type>
-FooMatcherPk<p1_type, ..., pk_type>
-Foo(p1_type p1, ..., pk_type pk) { ... }
-```
-
-When you write `Foo(v1, ..., vk)`, the compiler infers the types of
-the parameters `v1`, ..., and `vk` for you.  If you are not happy with
-the result of the type inference, you can specify the types by
-explicitly instantiating the template, as in `Foo<long, bool>(5, false)`.
-As said earlier, you don't get to (or need to) specify
-`arg_type` as that's determined by the context in which the matcher
-is used.
-
-You can assign the result of expression `Foo(p1, ..., pk)` to a
-variable of type `FooMatcherPk<p1_type, ..., pk_type>`.  This can be
-useful when composing matchers.  Matchers that don't have a parameter
-or have only one parameter have special types: you can assign `Foo()`
-to a `FooMatcher`-typed variable, and assign `Foo(p)` to a
-`FooMatcherP<p_type>`-typed variable.
-
-While you can instantiate a matcher template with reference types,
-passing the parameters by pointer usually makes your code more
-readable.  If, however, you still want to pass a parameter by
-reference, be aware that in the failure message generated by the
-matcher you will see the value of the referenced object but not its
-address.
-
-You can overload matchers with different numbers of parameters:
-```
-MATCHER_P(Blah, a, description_string_1) { ... }
-MATCHER_P2(Blah, a, b, description_string_2) { ... }
-```
-
-While it's tempting to always use the `MATCHER*` macros when defining
-a new matcher, you should also consider implementing
-`MatcherInterface` or using `MakePolymorphicMatcher()` instead (see
-the recipes that follow), especially if you need to use the matcher a
-lot.  While these approaches require more work, they give you more
-control on the types of the value being matched and the matcher
-parameters, which in general leads to better compiler error messages
-that pay off in the long run.  They also allow overloading matchers
-based on parameter types (as opposed to just based on the number of
-parameters).
-
-## Writing New Monomorphic Matchers ##
-
-A matcher of argument type `T` implements
-`::testing::MatcherInterface<T>` and does two things: it tests whether a
-value of type `T` matches the matcher, and can describe what kind of
-values it matches. The latter ability is used for generating readable
-error messages when expectations are violated.
-
-The interface looks like this:
-
-```
-class MatchResultListener {
- public:
-  ...
-  // Streams x to the underlying ostream; does nothing if the ostream
-  // is NULL.
-  template <typename T>
-  MatchResultListener& operator<<(const T& x);
-
-  // Returns the underlying ostream.
-  ::std::ostream* stream();
-};
-
-template <typename T>
-class MatcherInterface {
- public:
-  virtual ~MatcherInterface();
-
-  // Returns true iff the matcher matches x; also explains the match
-  // result to 'listener'.
-  virtual bool MatchAndExplain(T x, MatchResultListener* listener) const = 0;
-
-  // Describes this matcher to an ostream.
-  virtual void DescribeTo(::std::ostream* os) const = 0;
-
-  // Describes the negation of this matcher to an ostream.
-  virtual void DescribeNegationTo(::std::ostream* os) const;
-};
-```
-
-If you need a custom matcher but `Truly()` is not a good option (for
-example, you may not be happy with the way `Truly(predicate)`
-describes itself, or you may want your matcher to be polymorphic as
-`Eq(value)` is), you can define a matcher to do whatever you want in
-two steps: first implement the matcher interface, and then define a
-factory function to create a matcher instance. The second step is not
-strictly needed but it makes the syntax of using the matcher nicer.
-
-For example, you can define a matcher to test whether an `int` is
-divisible by 7 and then use it like this:
-```
-using ::testing::MakeMatcher;
-using ::testing::Matcher;
-using ::testing::MatcherInterface;
-using ::testing::MatchResultListener;
-
-class DivisibleBy7Matcher : public MatcherInterface<int> {
- public:
-  virtual bool MatchAndExplain(int n, MatchResultListener* listener) const {
-    return (n % 7) == 0;
-  }
-
-  virtual void DescribeTo(::std::ostream* os) const {
-    *os << "is divisible by 7";
-  }
-
-  virtual void DescribeNegationTo(::std::ostream* os) const {
-    *os << "is not divisible by 7";
-  }
-};
-
-inline Matcher<int> DivisibleBy7() {
-  return MakeMatcher(new DivisibleBy7Matcher);
-}
-...
-
-  EXPECT_CALL(foo, Bar(DivisibleBy7()));
-```
-
-You may improve the matcher message by streaming additional
-information to the `listener` argument in `MatchAndExplain()`:
-
-```
-class DivisibleBy7Matcher : public MatcherInterface<int> {
- public:
-  virtual bool MatchAndExplain(int n,
-                               MatchResultListener* listener) const {
-    const int remainder = n % 7;
-    if (remainder != 0) {
-      *listener << "the remainder is " << remainder;
-    }
-    return remainder == 0;
-  }
-  ...
-};
-```
-
-Then, `EXPECT_THAT(x, DivisibleBy7());` may general a message like this:
-```
-Value of: x
-Expected: is divisible by 7
-  Actual: 23 (the remainder is 2)
-```
-
-## Writing New Polymorphic Matchers ##
-
-You've learned how to write your own matchers in the previous
-recipe. Just one problem: a matcher created using `MakeMatcher()` only
-works for one particular type of arguments. If you want a
-_polymorphic_ matcher that works with arguments of several types (for
-instance, `Eq(x)` can be used to match a `value` as long as `value` ==
-`x` compiles -- `value` and `x` don't have to share the same type),
-you can learn the trick from `"gmock/gmock-matchers.h"` but it's a bit
-involved.
-
-Fortunately, most of the time you can define a polymorphic matcher
-easily with the help of `MakePolymorphicMatcher()`. Here's how you can
-define `NotNull()` as an example:
-
-```
-using ::testing::MakePolymorphicMatcher;
-using ::testing::MatchResultListener;
-using ::testing::NotNull;
-using ::testing::PolymorphicMatcher;
-
-class NotNullMatcher {
- public:
-  // To implement a polymorphic matcher, first define a COPYABLE class
-  // that has three members MatchAndExplain(), DescribeTo(), and
-  // DescribeNegationTo(), like the following.
-
-  // In this example, we want to use NotNull() with any pointer, so
-  // MatchAndExplain() accepts a pointer of any type as its first argument.
-  // In general, you can define MatchAndExplain() as an ordinary method or
-  // a method template, or even overload it.
-  template <typename T>
-  bool MatchAndExplain(T* p,
-                       MatchResultListener* /* listener */) const {
-    return p != NULL;
-  }
-
-  // Describes the property of a value matching this matcher.
-  void DescribeTo(::std::ostream* os) const { *os << "is not NULL"; }
-
-  // Describes the property of a value NOT matching this matcher.
-  void DescribeNegationTo(::std::ostream* os) const { *os << "is NULL"; }
-};
-
-// To construct a polymorphic matcher, pass an instance of the class
-// to MakePolymorphicMatcher().  Note the return type.
-inline PolymorphicMatcher<NotNullMatcher> NotNull() {
-  return MakePolymorphicMatcher(NotNullMatcher());
-}
-...
-
-  EXPECT_CALL(foo, Bar(NotNull()));  // The argument must be a non-NULL pointer.
-```
-
-**Note:** Your polymorphic matcher class does **not** need to inherit from
-`MatcherInterface` or any other class, and its methods do **not** need
-to be virtual.
-
-Like in a monomorphic matcher, you may explain the match result by
-streaming additional information to the `listener` argument in
-`MatchAndExplain()`.
-
-## Writing New Cardinalities ##
-
-A cardinality is used in `Times()` to tell Google Mock how many times
-you expect a call to occur. It doesn't have to be exact. For example,
-you can say `AtLeast(5)` or `Between(2, 4)`.
-
-If the built-in set of cardinalities doesn't suit you, you are free to
-define your own by implementing the following interface (in namespace
-`testing`):
-
-```
-class CardinalityInterface {
- public:
-  virtual ~CardinalityInterface();
-
-  // Returns true iff call_count calls will satisfy this cardinality.
-  virtual bool IsSatisfiedByCallCount(int call_count) const = 0;
-
-  // Returns true iff call_count calls will saturate this cardinality.
-  virtual bool IsSaturatedByCallCount(int call_count) const = 0;
-
-  // Describes self to an ostream.
-  virtual void DescribeTo(::std::ostream* os) const = 0;
-};
-```
-
-For example, to specify that a call must occur even number of times,
-you can write
-
-```
-using ::testing::Cardinality;
-using ::testing::CardinalityInterface;
-using ::testing::MakeCardinality;
-
-class EvenNumberCardinality : public CardinalityInterface {
- public:
-  virtual bool IsSatisfiedByCallCount(int call_count) const {
-    return (call_count % 2) == 0;
-  }
-
-  virtual bool IsSaturatedByCallCount(int call_count) const {
-    return false;
-  }
-
-  virtual void DescribeTo(::std::ostream* os) const {
-    *os << "called even number of times";
-  }
-};
-
-Cardinality EvenNumber() {
-  return MakeCardinality(new EvenNumberCardinality);
-}
-...
-
-  EXPECT_CALL(foo, Bar(3))
-      .Times(EvenNumber());
-```
-
-## Writing New Actions Quickly ##
-
-If the built-in actions don't work for you, and you find it
-inconvenient to use `Invoke()`, you can use a macro from the `ACTION*`
-family to quickly define a new action that can be used in your code as
-if it's a built-in action.
-
-By writing
-```
-ACTION(name) { statements; }
-```
-in a namespace scope (i.e. not inside a class or function), you will
-define an action with the given name that executes the statements.
-The value returned by `statements` will be used as the return value of
-the action.  Inside the statements, you can refer to the K-th
-(0-based) argument of the mock function as `argK`.  For example:
-```
-ACTION(IncrementArg1) { return ++(*arg1); }
-```
-allows you to write
-```
-... WillOnce(IncrementArg1());
-```
-
-Note that you don't need to specify the types of the mock function
-arguments.  Rest assured that your code is type-safe though:
-you'll get a compiler error if `*arg1` doesn't support the `++`
-operator, or if the type of `++(*arg1)` isn't compatible with the mock
-function's return type.
-
-Another example:
-```
-ACTION(Foo) {
-  (*arg2)(5);
-  Blah();
-  *arg1 = 0;
-  return arg0;
-}
-```
-defines an action `Foo()` that invokes argument #2 (a function pointer)
-with 5, calls function `Blah()`, sets the value pointed to by argument
-#1 to 0, and returns argument #0.
-
-For more convenience and flexibility, you can also use the following
-pre-defined symbols in the body of `ACTION`:
-
-| `argK_type` | The type of the K-th (0-based) argument of the mock function |
-|:------------|:-------------------------------------------------------------|
-| `args`      | All arguments of the mock function as a tuple                |
-| `args_type` | The type of all arguments of the mock function as a tuple    |
-| `return_type` | The return type of the mock function                         |
-| `function_type` | The type of the mock function                                |
-
-For example, when using an `ACTION` as a stub action for mock function:
-```
-int DoSomething(bool flag, int* ptr);
-```
-we have:
-
-| **Pre-defined Symbol** | **Is Bound To** |
-|:-----------------------|:----------------|
-| `arg0`                 | the value of `flag` |
-| `arg0_type`            | the type `bool` |
-| `arg1`                 | the value of `ptr` |
-| `arg1_type`            | the type `int*` |
-| `args`                 | the tuple `(flag, ptr)` |
-| `args_type`            | the type `::testing::tuple<bool, int*>` |
-| `return_type`          | the type `int`  |
-| `function_type`        | the type `int(bool, int*)` |
-
-## Writing New Parameterized Actions Quickly ##
-
-Sometimes you'll want to parameterize an action you define.  For that
-we have another macro
-```
-ACTION_P(name, param) { statements; }
-```
-
-For example,
-```
-ACTION_P(Add, n) { return arg0 + n; }
-```
-will allow you to write
-```
-// Returns argument #0 + 5.
-... WillOnce(Add(5));
-```
-
-For convenience, we use the term _arguments_ for the values used to
-invoke the mock function, and the term _parameters_ for the values
-used to instantiate an action.
-
-Note that you don't need to provide the type of the parameter either.
-Suppose the parameter is named `param`, you can also use the
-Google-Mock-defined symbol `param_type` to refer to the type of the
-parameter as inferred by the compiler.  For example, in the body of
-`ACTION_P(Add, n)` above, you can write `n_type` for the type of `n`.
-
-Google Mock also provides `ACTION_P2`, `ACTION_P3`, and etc to support
-multi-parameter actions.  For example,
-```
-ACTION_P2(ReturnDistanceTo, x, y) {
-  double dx = arg0 - x;
-  double dy = arg1 - y;
-  return sqrt(dx*dx + dy*dy);
-}
-```
-lets you write
-```
-... WillOnce(ReturnDistanceTo(5.0, 26.5));
-```
-
-You can view `ACTION` as a degenerated parameterized action where the
-number of parameters is 0.
-
-You can also easily define actions overloaded on the number of parameters:
-```
-ACTION_P(Plus, a) { ... }
-ACTION_P2(Plus, a, b) { ... }
-```
-
-## Restricting the Type of an Argument or Parameter in an ACTION ##
-
-For maximum brevity and reusability, the `ACTION*` macros don't ask
-you to provide the types of the mock function arguments and the action
-parameters.  Instead, we let the compiler infer the types for us.
-
-Sometimes, however, we may want to be more explicit about the types.
-There are several tricks to do that.  For example:
-```
-ACTION(Foo) {
-  // Makes sure arg0 can be converted to int.
-  int n = arg0;
-  ... use n instead of arg0 here ...
-}
-
-ACTION_P(Bar, param) {
-  // Makes sure the type of arg1 is const char*.
-  ::testing::StaticAssertTypeEq<const char*, arg1_type>();
-
-  // Makes sure param can be converted to bool.
-  bool flag = param;
-}
-```
-where `StaticAssertTypeEq` is a compile-time assertion in Google Test
-that verifies two types are the same.
-
-## Writing New Action Templates Quickly ##
-
-Sometimes you want to give an action explicit template parameters that
-cannot be inferred from its value parameters.  `ACTION_TEMPLATE()`
-supports that and can be viewed as an extension to `ACTION()` and
-`ACTION_P*()`.
-
-The syntax:
-```
-ACTION_TEMPLATE(ActionName,
-                HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
-                AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
-```
-
-defines an action template that takes _m_ explicit template parameters
-and _n_ value parameters, where _m_ is between 1 and 10, and _n_ is
-between 0 and 10.  `name_i` is the name of the i-th template
-parameter, and `kind_i` specifies whether it's a `typename`, an
-integral constant, or a template.  `p_i` is the name of the i-th value
-parameter.
-
-Example:
-```
-// DuplicateArg<k, T>(output) converts the k-th argument of the mock
-// function to type T and copies it to *output.
-ACTION_TEMPLATE(DuplicateArg,
-                // Note the comma between int and k:
-                HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
-                AND_1_VALUE_PARAMS(output)) {
-  *output = T(::testing::get<k>(args));
-}
-```
-
-To create an instance of an action template, write:
-```
-  ActionName<t1, ..., t_m>(v1, ..., v_n)
-```
-where the `t`s are the template arguments and the
-`v`s are the value arguments.  The value argument
-types are inferred by the compiler.  For example:
-```
-using ::testing::_;
-...
-  int n;
-  EXPECT_CALL(mock, Foo(_, _))
-      .WillOnce(DuplicateArg<1, unsigned char>(&n));
-```
-
-If you want to explicitly specify the value argument types, you can
-provide additional template arguments:
-```
-  ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
-```
-where `u_i` is the desired type of `v_i`.
-
-`ACTION_TEMPLATE` and `ACTION`/`ACTION_P*` can be overloaded on the
-number of value parameters, but not on the number of template
-parameters.  Without the restriction, the meaning of the following is
-unclear:
-
-```
-  OverloadedAction<int, bool>(x);
-```
-
-Are we using a single-template-parameter action where `bool` refers to
-the type of `x`, or a two-template-parameter action where the compiler
-is asked to infer the type of `x`?
-
-## Using the ACTION Object's Type ##
-
-If you are writing a function that returns an `ACTION` object, you'll
-need to know its type.  The type depends on the macro used to define
-the action and the parameter types.  The rule is relatively simple:
-
-| **Given Definition** | **Expression** | **Has Type** |
-|:---------------------|:---------------|:-------------|
-| `ACTION(Foo)`        | `Foo()`        | `FooAction`  |
-| `ACTION_TEMPLATE(Foo, HAS_m_TEMPLATE_PARAMS(...), AND_0_VALUE_PARAMS())` |	`Foo<t1, ..., t_m>()` | `FooAction<t1, ..., t_m>` |
-| `ACTION_P(Bar, param)` | `Bar(int_value)` | `BarActionP<int>` |
-| `ACTION_TEMPLATE(Bar, HAS_m_TEMPLATE_PARAMS(...), AND_1_VALUE_PARAMS(p1))` | `Bar<t1, ..., t_m>(int_value)` | `FooActionP<t1, ..., t_m, int>` |
-| `ACTION_P2(Baz, p1, p2)` | `Baz(bool_value, int_value)` | `BazActionP2<bool, int>` |
-| `ACTION_TEMPLATE(Baz, HAS_m_TEMPLATE_PARAMS(...), AND_2_VALUE_PARAMS(p1, p2))`| `Baz<t1, ..., t_m>(bool_value, int_value)` | `FooActionP2<t1, ..., t_m, bool, int>` |
-| ...                  | ...            | ...          |
-
-Note that we have to pick different suffixes (`Action`, `ActionP`,
-`ActionP2`, and etc) for actions with different numbers of value
-parameters, or the action definitions cannot be overloaded on the
-number of them.
-
-## Writing New Monomorphic Actions ##
-
-While the `ACTION*` macros are very convenient, sometimes they are
-inappropriate.  For example, despite the tricks shown in the previous
-recipes, they don't let you directly specify the types of the mock
-function arguments and the action parameters, which in general leads
-to unoptimized compiler error messages that can baffle unfamiliar
-users.  They also don't allow overloading actions based on parameter
-types without jumping through some hoops.
-
-An alternative to the `ACTION*` macros is to implement
-`::testing::ActionInterface<F>`, where `F` is the type of the mock
-function in which the action will be used. For example:
-
-```
-template <typename F>class ActionInterface {
- public:
-  virtual ~ActionInterface();
-
-  // Performs the action.  Result is the return type of function type
-  // F, and ArgumentTuple is the tuple of arguments of F.
-  //
-  // For example, if F is int(bool, const string&), then Result would
-  // be int, and ArgumentTuple would be ::testing::tuple<bool, const string&>.
-  virtual Result Perform(const ArgumentTuple& args) = 0;
-};
-
-using ::testing::_;
-using ::testing::Action;
-using ::testing::ActionInterface;
-using ::testing::MakeAction;
-
-typedef int IncrementMethod(int*);
-
-class IncrementArgumentAction : public ActionInterface<IncrementMethod> {
- public:
-  virtual int Perform(const ::testing::tuple<int*>& args) {
-    int* p = ::testing::get<0>(args);  // Grabs the first argument.
-    return *p++;
-  }
-};
-
-Action<IncrementMethod> IncrementArgument() {
-  return MakeAction(new IncrementArgumentAction);
-}
-...
-
-  EXPECT_CALL(foo, Baz(_))
-      .WillOnce(IncrementArgument());
-
-  int n = 5;
-  foo.Baz(&n);  // Should return 5 and change n to 6.
-```
-
-## Writing New Polymorphic Actions ##
-
-The previous recipe showed you how to define your own action. This is
-all good, except that you need to know the type of the function in
-which the action will be used. Sometimes that can be a problem. For
-example, if you want to use the action in functions with _different_
-types (e.g. like `Return()` and `SetArgPointee()`).
-
-If an action can be used in several types of mock functions, we say
-it's _polymorphic_. The `MakePolymorphicAction()` function template
-makes it easy to define such an action:
-
-```
-namespace testing {
-
-template <typename Impl>
-PolymorphicAction<Impl> MakePolymorphicAction(const Impl& impl);
-
-}  // namespace testing
-```
-
-As an example, let's define an action that returns the second argument
-in the mock function's argument list. The first step is to define an
-implementation class:
-
-```
-class ReturnSecondArgumentAction {
- public:
-  template <typename Result, typename ArgumentTuple>
-  Result Perform(const ArgumentTuple& args) const {
-    // To get the i-th (0-based) argument, use ::testing::get<i>(args).
-    return ::testing::get<1>(args);
-  }
-};
-```
-
-This implementation class does _not_ need to inherit from any
-particular class. What matters is that it must have a `Perform()`
-method template. This method template takes the mock function's
-arguments as a tuple in a **single** argument, and returns the result of
-the action. It can be either `const` or not, but must be invokable
-with exactly one template argument, which is the result type. In other
-words, you must be able to call `Perform<R>(args)` where `R` is the
-mock function's return type and `args` is its arguments in a tuple.
-
-Next, we use `MakePolymorphicAction()` to turn an instance of the
-implementation class into the polymorphic action we need. It will be
-convenient to have a wrapper for this:
-
-```
-using ::testing::MakePolymorphicAction;
-using ::testing::PolymorphicAction;
-
-PolymorphicAction<ReturnSecondArgumentAction> ReturnSecondArgument() {
-  return MakePolymorphicAction(ReturnSecondArgumentAction());
-}
-```
-
-Now, you can use this polymorphic action the same way you use the
-built-in ones:
-
-```
-using ::testing::_;
-
-class MockFoo : public Foo {
- public:
-  MOCK_METHOD2(DoThis, int(bool flag, int n));
-  MOCK_METHOD3(DoThat, string(int x, const char* str1, const char* str2));
-};
-...
-
-  MockFoo foo;
-  EXPECT_CALL(foo, DoThis(_, _))
-      .WillOnce(ReturnSecondArgument());
-  EXPECT_CALL(foo, DoThat(_, _, _))
-      .WillOnce(ReturnSecondArgument());
-  ...
-  foo.DoThis(true, 5);         // Will return 5.
-  foo.DoThat(1, "Hi", "Bye");  // Will return "Hi".
-```
-
-## Teaching Google Mock How to Print Your Values ##
-
-When an uninteresting or unexpected call occurs, Google Mock prints the
-argument values and the stack trace to help you debug.  Assertion
-macros like `EXPECT_THAT` and `EXPECT_EQ` also print the values in
-question when the assertion fails.  Google Mock and Google Test do this using
-Google Test's user-extensible value printer.
-
-This printer knows how to print built-in C++ types, native arrays, STL
-containers, and any type that supports the `<<` operator.  For other
-types, it prints the raw bytes in the value and hopes that you the
-user can figure it out.
-[Google Test's advanced guide](../../googletest/docs/advanced.md#teaching-google-test-how-to-print-your-values)
-explains how to extend the printer to do a better job at
-printing your particular type than to dump the bytes.

-# Macros for Defining Actions #
-
-## Problem ##
-
-Due to the lack of closures in C++, it currently requires some
-non-trivial effort to define a custom action in Google Mock.  For
-example, suppose you want to "increment the value pointed to by the
-second argument of the mock function and return it", you could write:
-
-```
-int IncrementArg1(Unused, int* p, Unused) {
-  return ++(*p);
-}
-
-... WillOnce(Invoke(IncrementArg1));
-```
-
-There are several things unsatisfactory about this approach:
-
-  * Even though the action only cares about the second argument of the mock function, its definition needs to list other arguments as dummies.  This is tedious.
-  * The defined action is usable only in mock functions that takes exactly 3 arguments - an unnecessary restriction.
-  * To use the action, one has to say `Invoke(IncrementArg1)`, which isn't as nice as `IncrementArg1()`.
-
-The latter two problems can be overcome using `MakePolymorphicAction()`,
-but it requires much more boilerplate code:
-
-```
-class IncrementArg1Action {
- public:
-  template <typename Result, typename ArgumentTuple>
-  Result Perform(const ArgumentTuple& args) const {
-    return ++(*tr1::get<1>(args));
-  }
-};
-
-PolymorphicAction<IncrementArg1Action> IncrementArg1() {
-  return MakePolymorphicAction(IncrementArg1Action());
-}
-
-... WillOnce(IncrementArg1());
-```
-
-Our goal is to allow defining custom actions with the least amount of
-boiler-plate C++ requires.
-
-## Solution ##
-
-We propose to introduce a new macro:
-```
-ACTION(name) { statements; }
-```
-
-Using this in a namespace scope will define an action with the given
-name that executes the statements.  Inside the statements, you can
-refer to the K-th (0-based) argument of the mock function as `argK`.
-For example:
-```
-ACTION(IncrementArg1) { return ++(*arg1); }
-```
-allows you to write
-```
-... WillOnce(IncrementArg1());
-```
-
-Note that you don't need to specify the types of the mock function
-arguments, as brevity is a top design goal here.  Rest assured that
-your code is still type-safe though: you'll get a compiler error if
-`*arg1` doesn't support the `++` operator, or if the type of
-`++(*arg1)` isn't compatible with the mock function's return type.
-
-Another example:
-```
-ACTION(Foo) {
-  (*arg2)(5);
-  Blah();
-  *arg1 = 0;
-  return arg0;
-}
-```
-defines an action `Foo()` that invokes argument #2 (a function pointer)
-with 5, calls function `Blah()`, sets the value pointed to by argument
-#1 to 0, and returns argument #0.
-
-For more convenience and flexibility, you can also use the following
-pre-defined symbols in the body of `ACTION`:
-
-| `argK_type` | The type of the K-th (0-based) argument of the mock function |
-|:------------|:-------------------------------------------------------------|
-| `args`      | All arguments of the mock function as a tuple                |
-| `args_type` | The type of all arguments of the mock function as a tuple    |
-| `return_type` | The return type of the mock function                         |
-| `function_type` | The type of the mock function                                |
-
-For example, when using an `ACTION` as a stub action for mock function:
-```
-int DoSomething(bool flag, int* ptr);
-```
-we have:
-| **Pre-defined Symbol** | **Is Bound To** |
-|:-----------------------|:----------------|
-| `arg0`                 | the value of `flag` |
-| `arg0_type`            | the type `bool` |
-| `arg1`                 | the value of `ptr` |
-| `arg1_type`            | the type `int*` |
-| `args`                 | the tuple `(flag, ptr)` |
-| `args_type`            | the type `std::tr1::tuple<bool, int*>` |
-| `return_type`          | the type `int`  |
-| `function_type`        | the type `int(bool, int*)` |
-
-## Parameterized actions ##
-
-Sometimes you'll want to parameterize the action.   For that we propose
-another macro
-```
-ACTION_P(name, param) { statements; }
-```
-
-For example,
-```
-ACTION_P(Add, n) { return arg0 + n; }
-```
-will allow you to write
-```
-// Returns argument #0 + 5.
-... WillOnce(Add(5));
-```
-
-For convenience, we use the term _arguments_ for the values used to
-invoke the mock function, and the term _parameters_ for the values
-used to instantiate an action.
-
-Note that you don't need to provide the type of the parameter either.
-Suppose the parameter is named `param`, you can also use the
-Google-Mock-defined symbol `param_type` to refer to the type of the
-parameter as inferred by the compiler.
-
-We will also provide `ACTION_P2`, `ACTION_P3`, and etc to support
-multi-parameter actions.  For example,
-```
-ACTION_P2(ReturnDistanceTo, x, y) {
-  double dx = arg0 - x;
-  double dy = arg1 - y;
-  return sqrt(dx*dx + dy*dy);
-}
-```
-lets you write
-```
-... WillOnce(ReturnDistanceTo(5.0, 26.5));
-```
-
-You can view `ACTION` as a degenerated parameterized action where the
-number of parameters is 0.
-
-## Advanced Usages ##
-
-### Overloading Actions ###
-
-You can easily define actions overloaded on the number of parameters:
-```
-ACTION_P(Plus, a) { ... }
-ACTION_P2(Plus, a, b) { ... }
-```
-
-### Restricting the Type of an Argument or Parameter ###
-
-For maximum brevity and reusability, the `ACTION*` macros don't let
-you specify the types of the mock function arguments and the action
-parameters.  Instead, we let the compiler infer the types for us.
-
-Sometimes, however, we may want to be more explicit about the types.
-There are several tricks to do that.  For example:
-```
-ACTION(Foo) {
-  // Makes sure arg0 can be converted to int.
-  int n = arg0;
-  ... use n instead of arg0 here ...
-}
-
-ACTION_P(Bar, param) {
-  // Makes sure the type of arg1 is const char*.
-  ::testing::StaticAssertTypeEq<const char*, arg1_type>();
-
-  // Makes sure param can be converted to bool.
-  bool flag = param;
-}
-```
-where `StaticAssertTypeEq` is a compile-time assertion we plan to add to
-Google Test (the name is chosen to match `static_assert` in C++0x).
-
-### Using the ACTION Object's Type ###
-
-If you are writing a function that returns an `ACTION` object, you'll
-need to know its type.  The type depends on the macro used to define
-the action and the parameter types.  The rule is relatively simple:
-| **Given Definition** | **Expression** | **Has Type** |
-|:---------------------|:---------------|:-------------|
-| `ACTION(Foo)`        | `Foo()`        | `FooAction`  |
-| `ACTION_P(Bar, param)` | `Bar(int_value)` | `BarActionP<int>` |
-| `ACTION_P2(Baz, p1, p2)` | `Baz(bool_value, int_value)` | `BazActionP2<bool, int>` |
-| ...                  | ...            | ...          |
-
-Note that we have to pick different suffixes (`Action`, `ActionP`,
-`ActionP2`, and etc) for actions with different numbers of parameters,
-or the action definitions cannot be overloaded on the number of
-parameters.
-
-## When to Use ##
-
-While the new macros are very convenient, please also consider other
-means of implementing actions (e.g. via `ActionInterface` or
-`MakePolymorphicAction()`), especially if you need to use the defined
-action a lot.  While the other approaches require more work, they give
-you more control on the types of the mock function arguments and the
-action parameters, which in general leads to better compiler error
-messages that pay off in the long run.  They also allow overloading
-actions based on parameter types, as opposed to just the number of
-parameters.
-
-## Related Work ##
-
-As you may have realized, the `ACTION*` macros resemble closures (also
-known as lambda expressions or anonymous functions).  Indeed, both of
-them seek to lower the syntactic overhead for defining a function.
-
-C++0x will support lambdas, but they are not part of C++ right now.
-Some non-standard libraries (most notably BLL or Boost Lambda Library)
-try to alleviate this problem.  However, they are not a good choice
-for defining actions as:
-
-  * They are non-standard and not widely installed.  Google Mock only depends on standard libraries and `tr1::tuple`, which is part of the new C++ standard and comes with gcc 4+.  We want to keep it that way.
-  * They are not trivial to learn.
-  * They will become obsolete when C++0x's lambda feature is widely supported.  We don't want to make our users use a dying library.
-  * Since they are based on operators, they are rather ad hoc: you cannot use statements, and you cannot pass the lambda arguments to a function, for example.
-  * They have subtle semantics that easily confuses new users.  For example, in expression `_1++ + foo++`, `foo` will be incremented only once where the expression is evaluated, while `_1` will be incremented every time the unnamed function is invoked.  This is far from intuitive.
-
-`ACTION*` avoid all these problems.
-
-## Future Improvements ##
-
-There may be a need for composing `ACTION*` definitions (i.e. invoking
-another `ACTION` inside the definition of one `ACTION*`).  We are not
-sure we want it yet, as one can get a similar effect by putting
-`ACTION` definitions in function templates and composing the function
-templates.  We'll revisit this based on user feedback.
-
-The reason we don't allow `ACTION*()` inside a function body is that
-the current C++ standard doesn't allow function-local types to be used
-to instantiate templates.  The upcoming C++0x standard will lift this
-restriction.  Once this feature is widely supported by compilers, we
-can revisit the implementation and add support for using `ACTION*()`
-inside a function.
-
-C++0x will also support lambda expressions.  When they become
-available, we may want to support using lambdas as actions.
-
-# Macros for Defining Matchers #
-
-Once the macros for defining actions are implemented, we plan to do
-the same for matchers:
-
-```
-MATCHER(name) { statements; }
-```
-
-where you can refer to the value being matched as `arg`.  For example,
-given:
-
-```
-MATCHER(IsPositive) { return arg > 0; }
-```
-
-you can use `IsPositive()` as a matcher that matches a value iff it is
-greater than 0.
-
-We will also add `MATCHER_P`, `MATCHER_P2`, and etc for parameterized
-matchers.

-# What Is Google C++ Mocking Framework? #
-When you write a prototype or test, often it's not feasible or wise to rely on real objects entirely. A **mock object** implements the same interface as a real object (so it can be used as one), but lets you specify at run time how it will be used and what it should do (which methods will be called? in which order? how many times? with what arguments? what will they return? etc).
-
-**Note:** It is easy to confuse the term _fake objects_ with mock objects. Fakes and mocks actually mean very different things in the Test-Driven Development (TDD) community:
-
-  * **Fake** objects have working implementations, but usually take some shortcut (perhaps to make the operations less expensive), which makes them not suitable for production. An in-memory file system would be an example of a fake.
-  * **Mocks** are objects pre-programmed with _expectations_, which form a specification of the calls they are expected to receive.
-
-If all this seems too abstract for you, don't worry - the most important thing to remember is that a mock allows you to check the _interaction_ between itself and code that uses it. The difference between fakes and mocks will become much clearer once you start to use mocks.
-
-**Google C++ Mocking Framework** (or **Google Mock** for short) is a library (sometimes we also call it a "framework" to make it sound cool) for creating mock classes and using them. It does to C++ what [jMock](http://www.jmock.org/) and [EasyMock](http://www.easymock.org/) do to Java.
-
-Using Google Mock involves three basic steps:
-
-  1. Use some simple macros to describe the interface you want to mock, and they will expand to the implementation of your mock class;
-  1. Create some mock objects and specify its expectations and behavior using an intuitive syntax;
-  1. Exercise code that uses the mock objects. Google Mock will catch any violation of the expectations as soon as it arises.
-
-# Why Google Mock? #
-While mock objects help you remove unnecessary dependencies in tests and make them fast and reliable, using mocks manually in C++ is _hard_:
-
-  * Someone has to implement the mocks. The job is usually tedious and error-prone. No wonder people go great distances to avoid it.
-  * The quality of those manually written mocks is a bit, uh, unpredictable. You may see some really polished ones, but you may also see some that were hacked up in a hurry and have all sorts of ad-hoc restrictions.
-  * The knowledge you gained from using one mock doesn't transfer to the next.
-
-In contrast, Java and Python programmers have some fine mock frameworks, which automate the creation of mocks. As a result, mocking is a proven effective technique and widely adopted practice in those communities. Having the right tool absolutely makes the difference.
-
-Google Mock was built to help C++ programmers. It was inspired by [jMock](http://www.jmock.org/) and [EasyMock](http://www.easymock.org/), but designed with C++'s specifics in mind. It is your friend if any of the following problems is bothering you:
-
-  * You are stuck with a sub-optimal design and wish you had done more prototyping before it was too late, but prototyping in C++ is by no means "rapid".
-  * Your tests are slow as they depend on too many libraries or use expensive resources (e.g. a database).
-  * Your tests are brittle as some resources they use are unreliable (e.g. the network).
-  * You want to test how your code handles a failure (e.g. a file checksum error), but it's not easy to cause one.
-  * You need to make sure that your module interacts with other modules in the right way, but it's hard to observe the interaction; therefore you resort to observing the side effects at the end of the action, which is awkward at best.
-  * You want to "mock out" your dependencies, except that they don't have mock implementations yet; and, frankly, you aren't thrilled by some of those hand-written mocks.
-
-We encourage you to use Google Mock as:
-
-  * a _design_ tool, for it lets you experiment with your interface design early and often. More iterations lead to better designs!
-  * a _testing_ tool to cut your tests' outbound dependencies and probe the interaction between your module and its collaborators.
-
-# Getting Started #
-Using Google Mock is easy! Inside your C++ source file, just `#include` `"gtest/gtest.h"` and `"gmock/gmock.h"`, and you are ready to go.
-
-# A Case for Mock Turtles #
-Let's look at an example. Suppose you are developing a graphics program that relies on a LOGO-like API for drawing. How would you test that it does the right thing? Well, you can run it and compare the screen with a golden screen snapshot, but let's admit it: tests like this are expensive to run and fragile (What if you just upgraded to a shiny new graphics card that has better anti-aliasing? Suddenly you have to update all your golden images.). It would be too painful if all your tests are like this. Fortunately, you learned about Dependency Injection and know the right thing to do: instead of having your application talk to the drawing API directly, wrap the API in an interface (say, `Turtle`) and code to that interface:
-
-```
-class Turtle {
-  ...
-  virtual ~Turtle() {}
-  virtual void PenUp() = 0;
-  virtual void PenDown() = 0;
-  virtual void Forward(int distance) = 0;
-  virtual void Turn(int degrees) = 0;
-  virtual void GoTo(int x, int y) = 0;
-  virtual int GetX() const = 0;
-  virtual int GetY() const = 0;
-};
-```
-
-(Note that the destructor of `Turtle` **must** be virtual, as is the case for **all** classes you intend to inherit from - otherwise the destructor of the derived class will not be called when you delete an object through a base pointer, and you'll get corrupted program states like memory leaks.)
-
-You can control whether the turtle's movement will leave a trace using `PenUp()` and `PenDown()`, and control its movement using `Forward()`, `Turn()`, and `GoTo()`. Finally, `GetX()` and `GetY()` tell you the current position of the turtle.
-
-Your program will normally use a real implementation of this interface. In tests, you can use a mock implementation instead. This allows you to easily check what drawing primitives your program is calling, with what arguments, and in which order. Tests written this way are much more robust (they won't break because your new machine does anti-aliasing differently), easier to read and maintain (the intent of a test is expressed in the code, not in some binary images), and run _much, much faster_.
-
-# Writing the Mock Class #
-If you are lucky, the mocks you need to use have already been implemented by some nice people. If, however, you find yourself in the position to write a mock class, relax - Google Mock turns this task into a fun game! (Well, almost.)
-
-## How to Define It ##
-Using the `Turtle` interface as example, here are the simple steps you need to follow:
-
-  1. Derive a class `MockTurtle` from `Turtle`.
-  1. Take a _virtual_ function of `Turtle` (while it's possible to [mock non-virtual methods using templates](CookBook.md#mocking-nonvirtual-methods), it's much more involved). Count how many arguments it has.
-  1. In the `public:` section of the child class, write `MOCK_METHODn();` (or `MOCK_CONST_METHODn();` if you are mocking a `const` method), where `n` is the number of the arguments; if you counted wrong, shame on you, and a compiler error will tell you so.
-  1. Now comes the fun part: you take the function signature, cut-and-paste the _function name_ as the _first_ argument to the macro, and leave what's left as the _second_ argument (in case you're curious, this is the _type of the function_).
-  1. Repeat until all virtual functions you want to mock are done.
-
-After the process, you should have something like:
-
-```
-#include "gmock/gmock.h"  // Brings in Google Mock.
-class MockTurtle : public Turtle {
- public:
-  ...
-  MOCK_METHOD0(PenUp, void());
-  MOCK_METHOD0(PenDown, void());
-  MOCK_METHOD1(Forward, void(int distance));
-  MOCK_METHOD1(Turn, void(int degrees));
-  MOCK_METHOD2(GoTo, void(int x, int y));
-  MOCK_CONST_METHOD0(GetX, int());
-  MOCK_CONST_METHOD0(GetY, int());
-};
-```
-
-You don't need to define these mock methods somewhere else - the `MOCK_METHOD*` macros will generate the definitions for you. It's that simple! Once you get the hang of it, you can pump out mock classes faster than your source-control system can handle your check-ins.
-
-**Tip:** If even this is too much work for you, you'll find the
-`gmock_gen.py` tool in Google Mock's `scripts/generator/` directory (courtesy of the [cppclean](http://code.google.com/p/cppclean/) project) useful.  This command-line
-tool requires that you have Python 2.4 installed.  You give it a C++ file and the name of an abstract class defined in it,
-and it will print the definition of the mock class for you.  Due to the
-complexity of the C++ language, this script may not always work, but
-it can be quite handy when it does.  For more details, read the [user documentation](../scripts/generator/README).
-
-## Where to Put It ##
-When you define a mock class, you need to decide where to put its definition. Some people put it in a `*_test.cc`. This is fine when the interface being mocked (say, `Foo`) is owned by the same person or team. Otherwise, when the owner of `Foo` changes it, your test could break. (You can't really expect `Foo`'s maintainer to fix every test that uses `Foo`, can you?)
-
-So, the rule of thumb is: if you need to mock `Foo` and it's owned by others, define the mock class in `Foo`'s package (better, in a `testing` sub-package such that you can clearly separate production code and testing utilities), and put it in a `mock_foo.h`. Then everyone can reference `mock_foo.h` from their tests. If `Foo` ever changes, there is only one copy of `MockFoo` to change, and only tests that depend on the changed methods need to be fixed.
-
-Another way to do it: you can introduce a thin layer `FooAdaptor` on top of `Foo` and code to this new interface. Since you own `FooAdaptor`, you can absorb changes in `Foo` much more easily. While this is more work initially, carefully choosing the adaptor interface can make your code easier to write and more readable (a net win in the long run), as you can choose `FooAdaptor` to fit your specific domain much better than `Foo` does.
-
-# Using Mocks in Tests #
-Once you have a mock class, using it is easy. The typical work flow is:
-
-  1. Import the Google Mock names from the `testing` namespace such that you can use them unqualified (You only have to do it once per file. Remember that namespaces are a good idea and good for your health.).
-  1. Create some mock objects.
-  1. Specify your expectations on them (How many times will a method be called? With what arguments? What should it do? etc.).
-  1. Exercise some code that uses the mocks; optionally, check the result using Google Test assertions. If a mock method is called more than expected or with wrong arguments, you'll get an error immediately.
-  1. When a mock is destructed, Google Mock will automatically check whether all expectations on it have been satisfied.
-
-Here's an example:
-
-```
-#include "path/to/mock-turtle.h"
-#include "gmock/gmock.h"
-#include "gtest/gtest.h"
-using ::testing::AtLeast;                     // #1
-
-TEST(PainterTest, CanDrawSomething) {
-  MockTurtle turtle;                          // #2
-  EXPECT_CALL(turtle, PenDown())              // #3
-      .Times(AtLeast(1));
-
-  Painter painter(&turtle);                   // #4
-
-  EXPECT_TRUE(painter.DrawCircle(0, 0, 10));
-}                                             // #5
-
-int main(int argc, char** argv) {
-  // The following line must be executed to initialize Google Mock
-  // (and Google Test) before running the tests.
-  ::testing::InitGoogleMock(&argc, argv);
-  return RUN_ALL_TESTS();
-}
-```
-
-As you might have guessed, this test checks that `PenDown()` is called at least once. If the `painter` object didn't call this method, your test will fail with a message like this:
-
-```
-path/to/my_test.cc:119: Failure
-Actual function call count doesn't match this expectation:
-Actually: never called;
-Expected: called at least once.
-```
-
-**Tip 1:** If you run the test from an Emacs buffer, you can hit `<Enter>` on the line number displayed in the error message to jump right to the failed expectation.
-
-**Tip 2:** If your mock objects are never deleted, the final verification won't happen. Therefore it's a good idea to use a heap leak checker in your tests when you allocate mocks on the heap.
-
-**Important note:** Google Mock requires expectations to be set **before** the mock functions are called, otherwise the behavior is **undefined**. In particular, you mustn't interleave `EXPECT_CALL()`s and calls to the mock functions.
-
-This means `EXPECT_CALL()` should be read as expecting that a call will occur _in the future_, not that a call has occurred. Why does Google Mock work like that? Well, specifying the expectation beforehand allows Google Mock to report a violation as soon as it arises, when the context (stack trace, etc) is still available. This makes debugging much easier.
-
-Admittedly, this test is contrived and doesn't do much. You can easily achieve the same effect without using Google Mock. However, as we shall reveal soon, Google Mock allows you to do _much more_ with the mocks.
-
-## Using Google Mock with Any Testing Framework ##
-If you want to use something other than Google Test (e.g. [CppUnit](http://sourceforge.net/projects/cppunit/) or
-[CxxTest](https://cxxtest.com/)) as your testing framework, just change the `main()` function in the previous section to:
-```
-int main(int argc, char** argv) {
-  // The following line causes Google Mock to throw an exception on failure,
-  // which will be interpreted by your testing framework as a test failure.
-  ::testing::GTEST_FLAG(throw_on_failure) = true;
-  ::testing::InitGoogleMock(&argc, argv);
-  ... whatever your testing framework requires ...
-}
-```
-
-This approach has a catch: it makes Google Mock throw an exception
-from a mock object's destructor sometimes.  With some compilers, this
-sometimes causes the test program to crash.  You'll still be able to
-notice that the test has failed, but it's not a graceful failure.
-
-A better solution is to use Google Test's
-[event listener API](../../googletest/docs/advanced.md#extending-google-test-by-handling-test-events)
-to report a test failure to your testing framework properly.  You'll need to
-implement the `OnTestPartResult()` method of the event listener interface, but it
-should be straightforward.
-
-If this turns out to be too much work, we suggest that you stick with
-Google Test, which works with Google Mock seamlessly (in fact, it is
-technically part of Google Mock.).  If there is a reason that you
-cannot use Google Test, please let us know.
-
-# Setting Expectations #
-The key to using a mock object successfully is to set the _right expectations_ on it. If you set the expectations too strict, your test will fail as the result of unrelated changes. If you set them too loose, bugs can slip through. You want to do it just right such that your test can catch exactly the kind of bugs you intend it to catch. Google Mock provides the necessary means for you to do it "just right."
-
-## General Syntax ##
-In Google Mock we use the `EXPECT_CALL()` macro to set an expectation on a mock method. The general syntax is:
-
-```
-EXPECT_CALL(mock_object, method(matchers))
-    .Times(cardinality)
-    .WillOnce(action)
-    .WillRepeatedly(action);
-```
-
-The macro has two arguments: first the mock object, and then the method and its arguments. Note that the two are separated by a comma (`,`), not a period (`.`). (Why using a comma? The answer is that it was necessary for technical reasons.)
-
-The macro can be followed by some optional _clauses_ that provide more information about the expectation. We'll discuss how each clause works in the coming sections.
-
-This syntax is designed to make an expectation read like English. For example, you can probably guess that
-
-```
-using ::testing::Return;
-...
-EXPECT_CALL(turtle, GetX())
-    .Times(5)
-    .WillOnce(Return(100))
-    .WillOnce(Return(150))
-    .WillRepeatedly(Return(200));
-```
-
-says that the `turtle` object's `GetX()` method will be called five times, it will return 100 the first time, 150 the second time, and then 200 every time. Some people like to call this style of syntax a Domain-Specific Language (DSL).
-
-**Note:** Why do we use a macro to do this? It serves two purposes: first it makes expectations easily identifiable (either by `grep` or by a human reader), and second it allows Google Mock to include the source file location of a failed expectation in messages, making debugging easier.
-
-## Matchers: What Arguments Do We Expect? ##
-When a mock function takes arguments, we must specify what arguments we are expecting; for example:
-
-```
-// Expects the turtle to move forward by 100 units.
-EXPECT_CALL(turtle, Forward(100));
-```
-
-Sometimes you may not want to be too specific (Remember that talk about tests being too rigid? Over specification leads to brittle tests and obscures the intent of tests. Therefore we encourage you to specify only what's necessary - no more, no less.). If you care to check that `Forward()` will be called but aren't interested in its actual argument, write `_` as the argument, which means "anything goes":
-
-```
-using ::testing::_;
-...
-// Expects the turtle to move forward.
-EXPECT_CALL(turtle, Forward(_));
-```
-
-`_` is an instance of what we call **matchers**. A matcher is like a predicate and can test whether an argument is what we'd expect. You can use a matcher inside `EXPECT_CALL()` wherever a function argument is expected.
-
-A list of built-in matchers can be found in the [CheatSheet](CheatSheet.md). For example, here's the `Ge` (greater than or equal) matcher:
-
-```
-using ::testing::Ge;
-...
-EXPECT_CALL(turtle, Forward(Ge(100)));
-```
-
-This checks that the turtle will be told to go forward by at least 100 units.
-
-## Cardinalities: How Many Times Will It Be Called? ##
-The first clause we can specify following an `EXPECT_CALL()` is `Times()`. We call its argument a **cardinality** as it tells _how many times_ the call should occur. It allows us to repeat an expectation many times without actually writing it as many times. More importantly, a cardinality can be "fuzzy", just like a matcher can be. This allows a user to express the intent of a test exactly.
-
-An interesting special case is when we say `Times(0)`. You may have guessed - it means that the function shouldn't be called with the given arguments at all, and Google Mock will report a Google Test failure whenever the function is (wrongfully) called.
-
-We've seen `AtLeast(n)` as an example of fuzzy cardinalities earlier. For the list of built-in cardinalities you can use, see the [CheatSheet](CheatSheet.md).
-
-The `Times()` clause can be omitted. **If you omit `Times()`, Google Mock will infer the cardinality for you.** The rules are easy to remember:
-
-  * If **neither** `WillOnce()` **nor** `WillRepeatedly()` is in the `EXPECT_CALL()`, the inferred cardinality is `Times(1)`.
-  * If there are `n WillOnce()`'s but **no** `WillRepeatedly()`, where `n` >= 1, the cardinality is `Times(n)`.
-  * If there are `n WillOnce()`'s and **one** `WillRepeatedly()`, where `n` >= 0, the cardinality is `Times(AtLeast(n))`.
-
-**Quick quiz:** what do you think will happen if a function is expected to be called twice but actually called four times?
-
-## Actions: What Should It Do? ##
-Remember that a mock object doesn't really have a working implementation? We as users have to tell it what to do when a method is invoked. This is easy in Google Mock.
-
-First, if the return type of a mock function is a built-in type or a pointer, the function has a **default action** (a `void` function will just return, a `bool` function will return `false`, and other functions will return 0). In addition, in C++ 11 and above, a mock function whose return type is default-constructible (i.e. has a default constructor) has a default action of returning a default-constructed value.  If you don't say anything, this behavior will be used.
-
-Second, if a mock function doesn't have a default action, or the default action doesn't suit you, you can specify the action to be taken each time the expectation matches using a series of `WillOnce()` clauses followed by an optional `WillRepeatedly()`. For example,
-
-```
-using ::testing::Return;
-...
-EXPECT_CALL(turtle, GetX())
-    .WillOnce(Return(100))
-    .WillOnce(Return(200))
-    .WillOnce(Return(300));
-```
-
-This says that `turtle.GetX()` will be called _exactly three times_ (Google Mock inferred this from how many `WillOnce()` clauses we've written, since we didn't explicitly write `Times()`), and will return 100, 200, and 300 respectively.
-
-```
-using ::testing::Return;
-...
-EXPECT_CALL(turtle, GetY())
-    .WillOnce(Return(100))
-    .WillOnce(Return(200))
-    .WillRepeatedly(Return(300));
-```
-
-says that `turtle.GetY()` will be called _at least twice_ (Google Mock knows this as we've written two `WillOnce()` clauses and a `WillRepeatedly()` while having no explicit `Times()`), will return 100 the first time, 200 the second time, and 300 from the third time on.
-
-Of course, if you explicitly write a `Times()`, Google Mock will not try to infer the cardinality itself. What if the number you specified is larger than there are `WillOnce()` clauses? Well, after all `WillOnce()`s are used up, Google Mock will do the _default_ action for the function every time (unless, of course, you have a `WillRepeatedly()`.).
-
-What can we do inside `WillOnce()` besides `Return()`? You can return a reference using `ReturnRef(variable)`, or invoke a pre-defined function, among [others](CheatSheet.md#actions).
-
-**Important note:** The `EXPECT_CALL()` statement evaluates the action clause only once, even though the action may be performed many times. Therefore you must be careful about side effects. The following may not do what you want:
-
-```
-int n = 100;
-EXPECT_CALL(turtle, GetX())
-.Times(4)
-.WillRepeatedly(Return(n++));
-```
-
-Instead of returning 100, 101, 102, ..., consecutively, this mock function will always return 100 as `n++` is only evaluated once. Similarly, `Return(new Foo)` will create a new `Foo` object when the `EXPECT_CALL()` is executed, and will return the same pointer every time. If you want the side effect to happen every time, you need to define a custom action, which we'll teach in the [CookBook](CookBook.md).
-
-Time for another quiz! What do you think the following means?
-
-```
-using ::testing::Return;
-...
-EXPECT_CALL(turtle, GetY())
-.Times(4)
-.WillOnce(Return(100));
-```
-
-Obviously `turtle.GetY()` is expected to be called four times. But if you think it will return 100 every time, think twice! Remember that one `WillOnce()` clause will be consumed each time the function is invoked and the default action will be taken afterwards. So the right answer is that `turtle.GetY()` will return 100 the first time, but **return 0 from the second time on**, as returning 0 is the default action for `int` functions.
-
-## Using Multiple Expectations ##
-So far we've only shown examples where you have a single expectation. More realistically, you're going to specify expectations on multiple mock methods, which may be from multiple mock objects.
-
-By default, when a mock method is invoked, Google Mock will search the expectations in the **reverse order** they are defined, and stop when an active expectation that matches the arguments is found (you can think of it as "newer rules override older ones."). If the matching expectation cannot take any more calls, you will get an upper-bound-violated failure. Here's an example:
-
-```
-using ::testing::_;
-...
-EXPECT_CALL(turtle, Forward(_));  // #1
-EXPECT_CALL(turtle, Forward(10))  // #2
-    .Times(2);
-```
-
-If `Forward(10)` is called three times in a row, the third time it will be an error, as the last matching expectation (#2) has been saturated. If, however, the third `Forward(10)` call is replaced by `Forward(20)`, then it would be OK, as now #1 will be the matching expectation.
-
-**Side note:** Why does Google Mock search for a match in the _reverse_ order of the expectations? The reason is that this allows a user to set up the default expectations in a mock object's constructor or the test fixture's set-up phase and then customize the mock by writing more specific expectations in the test body. So, if you have two expectations on the same method, you want to put the one with more specific matchers **after** the other, or the more specific rule would be shadowed by the more general one that comes after it.
-
-## Ordered vs Unordered Calls ##
-By default, an expectation can match a call even though an earlier expectation hasn't been satisfied. In other words, the calls don't have to occur in the order the expectations are specified.
-
-Sometimes, you may want all the expected calls to occur in a strict order. To say this in Google Mock is easy:
-
-```
-using ::testing::InSequence;
-...
-TEST(FooTest, DrawsLineSegment) {
-  ...
-  {
-    InSequence dummy;
-
-    EXPECT_CALL(turtle, PenDown());
-    EXPECT_CALL(turtle, Forward(100));
-    EXPECT_CALL(turtle, PenUp());
-  }
-  Foo();
-}
-```
-
-By creating an object of type `InSequence`, all expectations in its scope are put into a _sequence_ and have to occur _sequentially_. Since we are just relying on the constructor and destructor of this object to do the actual work, its name is really irrelevant.
-
-In this example, we test that `Foo()` calls the three expected functions in the order as written. If a call is made out-of-order, it will be an error.
-
-(What if you care about the relative order of some of the calls, but not all of them? Can you specify an arbitrary partial order? The answer is ... yes! If you are impatient, the details can be found in the [CookBook](CookBook.md#expecting-partially-ordered-calls).)
-
-## All Expectations Are Sticky (Unless Said Otherwise) ##
-Now let's do a quick quiz to see how well you can use this mock stuff already. How would you test that the turtle is asked to go to the origin _exactly twice_ (you want to ignore any other instructions it receives)?
-
-After you've come up with your answer, take a look at ours and compare notes (solve it yourself first - don't cheat!):
-
-```
-using ::testing::_;
-...
-EXPECT_CALL(turtle, GoTo(_, _))  // #1
-    .Times(AnyNumber());
-EXPECT_CALL(turtle, GoTo(0, 0))  // #2
-    .Times(2);
-```
-
-Suppose `turtle.GoTo(0, 0)` is called three times. In the third time, Google Mock will see that the arguments match expectation #2 (remember that we always pick the last matching expectation). Now, since we said that there should be only two such calls, Google Mock will report an error immediately. This is basically what we've told you in the "Using Multiple Expectations" section above.
-
-This example shows that **expectations in Google Mock are "sticky" by default**, in the sense that they remain active even after we have reached their invocation upper bounds. This is an important rule to remember, as it affects the meaning of the spec, and is **different** to how it's done in many other mocking frameworks (Why'd we do that? Because we think our rule makes the common cases easier to express and understand.).
-
-Simple? Let's see if you've really understood it: what does the following code say?
-
-```
-using ::testing::Return;
-...
-for (int i = n; i > 0; i--) {
-  EXPECT_CALL(turtle, GetX())
-      .WillOnce(Return(10*i));
-}
-```
-
-If you think it says that `turtle.GetX()` will be called `n` times and will return 10, 20, 30, ..., consecutively, think twice! The problem is that, as we said, expectations are sticky. So, the second time `turtle.GetX()` is called, the last (latest) `EXPECT_CALL()` statement will match, and will immediately lead to an "upper bound exceeded" error - this piece of code is not very useful!
-
-One correct way of saying that `turtle.GetX()` will return 10, 20, 30, ..., is to explicitly say that the expectations are _not_ sticky. In other words, they should _retire_ as soon as they are saturated:
-
-```
-using ::testing::Return;
-...
-for (int i = n; i > 0; i--) {
-  EXPECT_CALL(turtle, GetX())
-    .WillOnce(Return(10*i))
-    .RetiresOnSaturation();
-}
-```
-
-And, there's a better way to do it: in this case, we expect the calls to occur in a specific order, and we line up the actions to match the order. Since the order is important here, we should make it explicit using a sequence:
-
-```
-using ::testing::InSequence;
-using ::testing::Return;
-...
-{
-  InSequence s;
-
-  for (int i = 1; i <= n; i++) {
-    EXPECT_CALL(turtle, GetX())
-        .WillOnce(Return(10*i))
-        .RetiresOnSaturation();
-  }
-}
-```
-
-By the way, the other situation where an expectation may _not_ be sticky is when it's in a sequence - as soon as another expectation that comes after it in the sequence has been used, it automatically retires (and will never be used to match any call).
-
-## Uninteresting Calls ##
-A mock object may have many methods, and not all of them are that interesting. For example, in some tests we may not care about how many times `GetX()` and `GetY()` get called.
-
-In Google Mock, if you are not interested in a method, just don't say anything about it. If a call to this method occurs, you'll see a warning in the test output, but it won't be a failure.
-
-# What Now? #
-Congratulations! You've learned enough about Google Mock to start using it. Now, you might want to join the [googlemock](http://groups.google.com/group/googlemock) discussion group and actually write some tests using Google Mock - it will be fun. Hey, it may even be addictive - you've been warned.
-
-Then, if you feel like increasing your mock quotient, you should move on to the [CookBook](CookBook.md). You can learn many advanced features of Google Mock there -- and advance your level of enjoyment and testing bliss.

-
-## When I call a method on my mock object, the method for the real object is invoked instead.  What's the problem? ##
-
-In order for a method to be mocked, it must be _virtual_, unless you use the [high-perf dependency injection technique](CookBook.md#mocking-nonvirtual-methods).
-
-## I wrote some matchers.  After I upgraded to a new version of Google Mock, they no longer compile.  What's going on? ##
-
-After version 1.4.0 of Google Mock was released, we had an idea on how
-to make it easier to write matchers that can generate informative
-messages efficiently.  We experimented with this idea and liked what
-we saw.  Therefore we decided to implement it.
-
-Unfortunately, this means that if you have defined your own matchers
-by implementing `MatcherInterface` or using `MakePolymorphicMatcher()`,
-your definitions will no longer compile.  Matchers defined using the
-`MATCHER*` family of macros are not affected.
-
-Sorry for the hassle if your matchers are affected.  We believe it's
-in everyone's long-term interest to make this change sooner than
-later.  Fortunately, it's usually not hard to migrate an existing
-matcher to the new API.  Here's what you need to do:
-
-If you wrote your matcher like this:
-```
-// Old matcher definition that doesn't work with the latest
-// Google Mock.
-using ::testing::MatcherInterface;
-...
-class MyWonderfulMatcher : public MatcherInterface<MyType> {
- public:
-  ...
-  virtual bool Matches(MyType value) const {
-    // Returns true if value matches.
-    return value.GetFoo() > 5;
-  }
-  ...
-};
-```
-
-you'll need to change it to:
-```
-// New matcher definition that works with the latest Google Mock.
-using ::testing::MatcherInterface;
-using ::testing::MatchResultListener;
-...
-class MyWonderfulMatcher : public MatcherInterface<MyType> {
- public:
-  ...
-  virtual bool MatchAndExplain(MyType value,
-                               MatchResultListener* listener) const {
-    // Returns true if value matches.
-    return value.GetFoo() > 5;
-  }
-  ...
-};
-```
-(i.e. rename `Matches()` to `MatchAndExplain()` and give it a second
-argument of type `MatchResultListener*`.)
-
-If you were also using `ExplainMatchResultTo()` to improve the matcher
-message:
-```
-// Old matcher definition that doesn't work with the lastest
-// Google Mock.
-using ::testing::MatcherInterface;
-...
-class MyWonderfulMatcher : public MatcherInterface<MyType> {
- public:
-  ...
-  virtual bool Matches(MyType value) const {
-    // Returns true if value matches.
-    return value.GetFoo() > 5;
-  }
-
-  virtual void ExplainMatchResultTo(MyType value,
-                                    ::std::ostream* os) const {
-    // Prints some helpful information to os to help
-    // a user understand why value matches (or doesn't match).
-    *os << "the Foo property is " << value.GetFoo();
-  }
-  ...
-};
-```
-
-you should move the logic of `ExplainMatchResultTo()` into
-`MatchAndExplain()`, using the `MatchResultListener` argument where
-the `::std::ostream` was used:
-```
-// New matcher definition that works with the latest Google Mock.
-using ::testing::MatcherInterface;
-using ::testing::MatchResultListener;
-...
-class MyWonderfulMatcher : public MatcherInterface<MyType> {
- public:
-  ...
-  virtual bool MatchAndExplain(MyType value,
-                               MatchResultListener* listener) const {
-    // Returns true if value matches.
-    *listener << "the Foo property is " << value.GetFoo();
-    return value.GetFoo() > 5;
-  }
-  ...
-};
-```
-
-If your matcher is defined using `MakePolymorphicMatcher()`:
-```
-// Old matcher definition that doesn't work with the latest
-// Google Mock.
-using ::testing::MakePolymorphicMatcher;
-...
-class MyGreatMatcher {
- public:
-  ...
-  bool Matches(MyType value) const {
-    // Returns true if value matches.
-    return value.GetBar() < 42;
-  }
-  ...
-};
-... MakePolymorphicMatcher(MyGreatMatcher()) ...
-```
-
-you should rename the `Matches()` method to `MatchAndExplain()` and
-add a `MatchResultListener*` argument (the same as what you need to do
-for matchers defined by implementing `MatcherInterface`):
-```
-// New matcher definition that works with the latest Google Mock.
-using ::testing::MakePolymorphicMatcher;
-using ::testing::MatchResultListener;
-...
-class MyGreatMatcher {
- public:
-  ...
-  bool MatchAndExplain(MyType value,
-                       MatchResultListener* listener) const {
-    // Returns true if value matches.
-    return value.GetBar() < 42;
-  }
-  ...
-};
-... MakePolymorphicMatcher(MyGreatMatcher()) ...
-```
-
-If your polymorphic matcher uses `ExplainMatchResultTo()` for better
-failure messages:
-```
-// Old matcher definition that doesn't work with the latest
-// Google Mock.
-using ::testing::MakePolymorphicMatcher;
-...
-class MyGreatMatcher {
- public:
-  ...
-  bool Matches(MyType value) const {
-    // Returns true if value matches.
-    return value.GetBar() < 42;
-  }
-  ...
-};
-void ExplainMatchResultTo(const MyGreatMatcher& matcher,
-                          MyType value,
-                          ::std::ostream* os) {
-  // Prints some helpful information to os to help
-  // a user understand why value matches (or doesn't match).
-  *os << "the Bar property is " << value.GetBar();
-}
-... MakePolymorphicMatcher(MyGreatMatcher()) ...
-```
-
-you'll need to move the logic inside `ExplainMatchResultTo()` to
-`MatchAndExplain()`:
-```
-// New matcher definition that works with the latest Google Mock.
-using ::testing::MakePolymorphicMatcher;
-using ::testing::MatchResultListener;
-...
-class MyGreatMatcher {
- public:
-  ...
-  bool MatchAndExplain(MyType value,
-                       MatchResultListener* listener) const {
-    // Returns true if value matches.
-    *listener << "the Bar property is " << value.GetBar();
-    return value.GetBar() < 42;
-  }
-  ...
-};
-... MakePolymorphicMatcher(MyGreatMatcher()) ...
-```

-need any help.
-
-## When using Google Mock, do I have to use Google Test as the testing framework?  I have my favorite testing framework and don't want to switch. ##
-
-Google Mock works out of the box with Google Test.  However, it's easy
-to configure it to work with any testing framework of your choice.
-[Here](ForDummies.md#using-google-mock-with-any-testing-framework) is how.
-
-## How am I supposed to make sense of these horrible template errors? ##
-
-If you are confused by the compiler errors gcc threw at you,
-try consulting the _Google Mock Doctor_ tool first.  What it does is to
-scan stdin for gcc error messages, and spit out diagnoses on the
-problems (we call them diseases) your code has.
-
-To "install", run command:
-```
-alias gmd='<path to googlemock>/scripts/gmock_doctor.py'
-```
-
-To use it, do:
-```
-<your-favorite-build-command> <your-test> 2>&1 | gmd
-```
-
-For example:
-```
-make my_test 2>&1 | gmd
-```
-
-Or you can run `gmd` and copy-n-paste gcc's error messages to it.
-
-## Can I mock a variadic function? ##
-
-You cannot mock a variadic function (i.e. a function taking ellipsis
-(`...`) arguments) directly in Google Mock.
-
-The problem is that in general, there is _no way_ for a mock object to
-know how many arguments are passed to the variadic method, and what
-the arguments' types are.  Only the _author of the base class_ knows
-the protocol, and we cannot look into their head.
-
-Therefore, to mock such a function, the _user_ must teach the mock
-object how to figure out the number of arguments and their types.  One
-way to do it is to provide overloaded versions of the function.
-
-Ellipsis arguments are inherited from C and not really a C++ feature.
-They are unsafe to use and don't work with arguments that have
-constructors or destructors.  Therefore we recommend to avoid them in
-C++ as much as possible.
-
-## MSVC gives me warning C4301 or C4373 when I define a mock method with a const parameter.  Why? ##
-
-If you compile this using Microsoft Visual C++ 2005 SP1:
-```
-class Foo {
-  ...
-  virtual void Bar(const int i) = 0;
-};
-
-class MockFoo : public Foo {
-  ...
-  MOCK_METHOD1(Bar, void(const int i));
-};
-```
-You may get the following warning:
-```
-warning C4301: 'MockFoo::Bar': overriding virtual function only differs from 'Foo::Bar' by const/volatile qualifier
-```
-
-This is a MSVC bug.  The same code compiles fine with gcc ,for
-example.  If you use Visual C++ 2008 SP1, you would get the warning:
-```
-warning C4373: 'MockFoo::Bar': virtual function overrides 'Foo::Bar', previous versions of the compiler did not override when parameters only differed by const/volatile qualifiers
-```
-
-In C++, if you _declare_ a function with a `const` parameter, the
-`const` modifier is _ignored_.  Therefore, the `Foo` base class above
-is equivalent to:
-```
-class Foo {
-  ...
-  virtual void Bar(int i) = 0;  // int or const int?  Makes no difference.
-};
-```
-
-In fact, you can _declare_ Bar() with an `int` parameter, and _define_
-it with a `const int` parameter.  The compiler will still match them
-up.
-
-Since making a parameter `const` is meaningless in the method
-_declaration_, we recommend to remove it in both `Foo` and `MockFoo`.
-That should workaround the VC bug.
-
-Note that we are talking about the _top-level_ `const` modifier here.
-If the function parameter is passed by pointer or reference, declaring
-the _pointee_ or _referee_ as `const` is still meaningful.  For
-example, the following two declarations are _not_ equivalent:
-```
-void Bar(int* p);        // Neither p nor *p is const.
-void Bar(const int* p);  // p is not const, but *p is.
-```
-
-## I have a huge mock class, and Microsoft Visual C++ runs out of memory when compiling it.  What can I do? ##
-
-We've noticed that when the `/clr` compiler flag is used, Visual C++
-uses 5~6 times as much memory when compiling a mock class.  We suggest
-to avoid `/clr` when compiling native C++ mocks.
-
-## I can't figure out why Google Mock thinks my expectations are not satisfied.  What should I do? ##
-
-You might want to run your test with
-`--gmock_verbose=info`.  This flag lets Google Mock print a trace
-of every mock function call it receives.  By studying the trace,
-you'll gain insights on why the expectations you set are not met.
-
-## How can I assert that a function is NEVER called? ##
-
-```
-EXPECT_CALL(foo, Bar(_))
-    .Times(0);
-```
-
-## I have a failed test where Google Mock tells me TWICE that a particular expectation is not satisfied.  Isn't this redundant? ##
-
-When Google Mock detects a failure, it prints relevant information
-(the mock function arguments, the state of relevant expectations, and
-etc) to help the user debug.  If another failure is detected, Google
-Mock will do the same, including printing the state of relevant
-expectations.
-
-Sometimes an expectation's state didn't change between two failures,
-and you'll see the same description of the state twice.  They are
-however _not_ redundant, as they refer to _different points in time_.
-The fact they are the same _is_ interesting information.
-
-## I get a heap check failure when using a mock object, but using a real object is fine.  What can be wrong? ##
-
-Does the class (hopefully a pure interface) you are mocking have a
-virtual destructor?
-
-Whenever you derive from a base class, make sure its destructor is
-virtual.  Otherwise Bad Things will happen.  Consider the following
-code:
-
-```
-class Base {
- public:
-  // Not virtual, but should be.
-  ~Base() { ... }
-  ...
-};
-
-class Derived : public Base {
- public:
-  ...
- private:
-  std::string value_;
-};
-
-...
-  Base* p = new Derived;
-  ...
-  delete p;  // Surprise! ~Base() will be called, but ~Derived() will not
-             // - value_ is leaked.
-```
-
-By changing `~Base()` to virtual, `~Derived()` will be correctly
-called when `delete p` is executed, and the heap checker
-will be happy.
-
-## The "newer expectations override older ones" rule makes writing expectations awkward.  Why does Google Mock do that? ##
-
-When people complain about this, often they are referring to code like:
-
-```
-// foo.Bar() should be called twice, return 1 the first time, and return
-// 2 the second time.  However, I have to write the expectations in the
-// reverse order.  This sucks big time!!!
-EXPECT_CALL(foo, Bar())
-    .WillOnce(Return(2))
-    .RetiresOnSaturation();
-EXPECT_CALL(foo, Bar())
-    .WillOnce(Return(1))
-    .RetiresOnSaturation();
-```
-
-The problem is that they didn't pick the **best** way to express the test's
-intent.
-
-By default, expectations don't have to be matched in _any_ particular
-order.  If you want them to match in a certain order, you need to be
-explicit.  This is Google Mock's (and jMock's) fundamental philosophy: it's
-easy to accidentally over-specify your tests, and we want to make it
-harder to do so.
-
-There are two better ways to write the test spec.  You could either
-put the expectations in sequence:
-
-```
-// foo.Bar() should be called twice, return 1 the first time, and return
-// 2 the second time.  Using a sequence, we can write the expectations
-// in their natural order.
-{
-  InSequence s;
-  EXPECT_CALL(foo, Bar())
-      .WillOnce(Return(1))
-      .RetiresOnSaturation();
-  EXPECT_CALL(foo, Bar())
-      .WillOnce(Return(2))
-      .RetiresOnSaturation();
-}
-```
-
-or you can put the sequence of actions in the same expectation:
-
-```
-// foo.Bar() should be called twice, return 1 the first time, and return
-// 2 the second time.
-EXPECT_CALL(foo, Bar())
-    .WillOnce(Return(1))
-    .WillOnce(Return(2))
-    .RetiresOnSaturation();
-```
-
-Back to the original questions: why does Google Mock search the
-expectations (and `ON_CALL`s) from back to front?  Because this
-allows a user to set up a mock's behavior for the common case early
-(e.g. in the mock's constructor or the test fixture's set-up phase)
-and customize it with more specific rules later.  If Google Mock
-searches from front to back, this very useful pattern won't be
-possible.
-
-## Google Mock prints a warning when a function without EXPECT\_CALL is called, even if I have set its behavior using ON\_CALL.  Would it be reasonable not to show the warning in this case? ##
-
-When choosing between being neat and being safe, we lean toward the
-latter.  So the answer is that we think it's better to show the
-warning.
-
-Often people write `ON_CALL`s in the mock object's
-constructor or `SetUp()`, as the default behavior rarely changes from
-test to test.  Then in the test body they set the expectations, which
-are often different for each test.  Having an `ON_CALL` in the set-up
-part of a test doesn't mean that the calls are expected.  If there's
-no `EXPECT_CALL` and the method is called, it's possibly an error.  If
-we quietly let the call go through without notifying the user, bugs
-may creep in unnoticed.
-
-If, however, you are sure that the calls are OK, you can write
-
-```
-EXPECT_CALL(foo, Bar(_))
-    .WillRepeatedly(...);
-```
-
-instead of
-
-```
-ON_CALL(foo, Bar(_))
-    .WillByDefault(...);
-```
-
-This tells Google Mock that you do expect the calls and no warning should be
-printed.
-
-Also, you can control the verbosity using the `--gmock_verbose` flag.
-If you find the output too noisy when debugging, just choose a less
-verbose level.
-
-## How can I delete the mock function's argument in an action? ##
-
-If you find yourself needing to perform some action that's not
-supported by Google Mock directly, remember that you can define your own
-actions using
-[MakeAction()](CookBook.md#writing-new-actions) or
-[MakePolymorphicAction()](CookBook.md#writing_new_polymorphic_actions),
-or you can write a stub function and invoke it using
-[Invoke()](CookBook.md#using-functions_methods_functors).
-
-## MOCK\_METHODn()'s second argument looks funny.  Why don't you use the MOCK\_METHODn(Method, return\_type, arg\_1, ..., arg\_n) syntax? ##
-
-What?!  I think it's beautiful. :-)
-
-While which syntax looks more natural is a subjective matter to some
-extent, Google Mock's syntax was chosen for several practical advantages it
-has.
-
-Try to mock a function that takes a map as an argument:
-```
-virtual int GetSize(const map<int, std::string>& m);
-```
-
-Using the proposed syntax, it would be:
-```
-MOCK_METHOD1(GetSize, int, const map<int, std::string>& m);
-```
-
-Guess what?  You'll get a compiler error as the compiler thinks that
-`const map<int, std::string>& m` are **two**, not one, arguments. To work
-around this you can use `typedef` to give the map type a name, but
-that gets in the way of your work.  Google Mock's syntax avoids this
-problem as the function's argument types are protected inside a pair
-of parentheses:
-```
-// This compiles fine.
-MOCK_METHOD1(GetSize, int(const map<int, std::string>& m));
-```
-
-You still need a `typedef` if the return type contains an unprotected
-comma, but that's much rarer.
-
-Other advantages include:
-  1. `MOCK_METHOD1(Foo, int, bool)` can leave a reader wonder whether the method returns `int` or `bool`, while there won't be such confusion using Google Mock's syntax.
-  1. The way Google Mock describes a function type is nothing new, although many people may not be familiar with it.  The same syntax was used in C, and the `function` library in `tr1` uses this syntax extensively.  Since `tr1` will become a part of the new version of STL, we feel very comfortable to be consistent with it.
-  1. The function type syntax is also used in other parts of Google Mock's API (e.g. the action interface) in order to make the implementation tractable. A user needs to learn it anyway in order to utilize Google Mock's more advanced features.  We'd as well stick to the same syntax in `MOCK_METHOD*`!
-
-## My code calls a static/global function.  Can I mock it? ##
-
-You can, but you need to make some changes.
-
-In general, if you find yourself needing to mock a static function,
-it's a sign that your modules are too tightly coupled (and less
-flexible, less reusable, less testable, etc).  You are probably better
-off defining a small interface and call the function through that
-interface, which then can be easily mocked.  It's a bit of work
-initially, but usually pays for itself quickly.
-
-This Google Testing Blog
-[post](https://testing.googleblog.com/2008/06/defeat-static-cling.html)
-says it excellently.  Check it out.
-
-## My mock object needs to do complex stuff.  It's a lot of pain to specify the actions.  Google Mock sucks! ##
-
-I know it's not a question, but you get an answer for free any way. :-)
-
-With Google Mock, you can create mocks in C++ easily.  And people might be
-tempted to use them everywhere. Sometimes they work great, and
-sometimes you may find them, well, a pain to use. So, what's wrong in
-the latter case?
-
-When you write a test without using mocks, you exercise the code and
-assert that it returns the correct value or that the system is in an
-expected state.  This is sometimes called "state-based testing".
-
-Mocks are great for what some call "interaction-based" testing:
-instead of checking the system state at the very end, mock objects
-verify that they are invoked the right way and report an error as soon
-as it arises, giving you a handle on the precise context in which the
-error was triggered.  This is often more effective and economical to
-do than state-based testing.
-
-If you are doing state-based testing and using a test double just to
-simulate the real object, you are probably better off using a fake.
-Using a mock in this case causes pain, as it's not a strong point for
-mocks to perform complex actions.  If you experience this and think
-that mocks suck, you are just not using the right tool for your
-problem. Or, you might be trying to solve the wrong problem. :-)
-
-## I got a warning "Uninteresting function call encountered - default action taken.."  Should I panic? ##
-
-By all means, NO!  It's just an FYI.
-
-What it means is that you have a mock function, you haven't set any
-expectations on it (by Google Mock's rule this means that you are not
-interested in calls to this function and therefore it can be called
-any number of times), and it is called.  That's OK - you didn't say
-it's not OK to call the function!
-
-What if you actually meant to disallow this function to be called, but
-forgot to write `EXPECT_CALL(foo, Bar()).Times(0)`?  While
-one can argue that it's the user's fault, Google Mock tries to be nice and
-prints you a note.
-
-So, when you see the message and believe that there shouldn't be any
-uninteresting calls, you should investigate what's going on.  To make
-your life easier, Google Mock prints the function name and arguments
-when an uninteresting call is encountered.
-
-## I want to define a custom action.  Should I use Invoke() or implement the action interface? ##
-
-Either way is fine - you want to choose the one that's more convenient
-for your circumstance.
-
-Usually, if your action is for a particular function type, defining it
-using `Invoke()` should be easier; if your action can be used in
-functions of different types (e.g. if you are defining
-`Return(value)`), `MakePolymorphicAction()` is
-easiest.  Sometimes you want precise control on what types of
-functions the action can be used in, and implementing
-`ActionInterface` is the way to go here. See the implementation of
-`Return()` in `include/gmock/gmock-actions.h` for an example.
-
-## I'm using the set-argument-pointee action, and the compiler complains about "conflicting return type specified".  What does it mean? ##
-
-You got this error as Google Mock has no idea what value it should return
-when the mock method is called.  `SetArgPointee()` says what the
-side effect is, but doesn't say what the return value should be.  You
-need `DoAll()` to chain a `SetArgPointee()` with a `Return()`.
-
-See this [recipe](CookBook.md#mocking_side_effects) for more details and an example.

-## My question is not in your FAQ! ##
-
-If you cannot find the answer to your question in this FAQ, there are
-some other resources you can use:
-
-  1. search the mailing list [archive](http://groups.google.com/group/googlemock/topics),
-  1. ask it on [googlemock@googlegroups.com](mailto:googlemock@googlegroups.com) and someone will answer it (to prevent spam, we require you to join the [discussion group](http://groups.google.com/group/googlemock) before you can post.).
-
-Please note that creating an issue in the
-[issue tracker](https://github.com/google/googletest/issues) is _not_
-a good way to get your answer, as it is monitored infrequently by a
-very small number of people.
-
-When asking a question, it's helpful to provide as much of the
-following information as possible (people cannot help you if there's
-not enough information in your question):
-
-  * the version (or the revision number if you check out from SVN directly) of Google Mock you use (Google Mock is under active development, so it's possible that your problem has been solved in a later version),
-  * your operating system,
-  * the name and version of your compiler,
-  * the complete command line flags you give to your compiler,
-  * the complete compiler error messages (if the question is about compilation),
-  * the _actual_ code (ideally, a minimal but complete program) that has the problem you encounter.

-As any non-trivial software system, Google Mock has some known limitations and problems.  We are working on improving it, and welcome your help!  The follow is a list of issues we know about.
-
-
-
-## README contains outdated information on Google Mock's compatibility with other testing frameworks ##
-
-The `README` file in release 1.1.0 still says that Google Mock only works with Google Test.  Actually, you can configure Google Mock to work with any testing framework you choose.
-
-## Tests failing on machines using Power PC CPUs (e.g. some Macs) ##
-
-`gmock_output_test` and `gmock-printers_test` are known to fail with Power PC CPUs.  This is due to portability issues with these tests, and is not an indication of problems in Google Mock itself.  You can safely ignore them.
-
-## Failed to resolve libgtest.so.0 in tests when built against installed Google Test ##
-
-This only applies if you manually built and installed Google Test, and then built a Google Mock against it (either explicitly, or because gtest-config was in your path post-install). In this situation, Libtool has a known issue with certain systems' ldconfig setup:
-
-http://article.gmane.org/gmane.comp.sysutils.automake.general/9025
-
-This requires a manual run of "sudo ldconfig" after the "sudo make install" for Google Test before any binaries which link against it can be executed. This isn't a bug in our install, but we should at least have documented it or hacked a work-around into our install. We should have one of these solutions in our next release.

-// The ACTION* family of macros can be used in a namespace scope to
-// define custom actions easily.  The syntax:
-//
-//   ACTION(name) { statements; }
-//
-// will define an action with the given name that executes the
-// statements.  The value returned by the statements will be used as
-// the return value of the action.  Inside the statements, you can
-// refer to the K-th (0-based) argument of the mock function by
-// 'argK', and refer to its type by 'argK_type'.  For example:
-//
-//   ACTION(IncrementArg1) {
-//     arg1_type temp = arg1;
-//     return ++(*temp);
-//   }
-//
-// allows you to write
-//
-//   ...WillOnce(IncrementArg1());
-//
-// You can also refer to the entire argument tuple and its type by
-// 'args' and 'args_type', and refer to the mock function type and its
-// return type by 'function_type' and 'return_type'.
-//
-// Note that you don't need to specify the types of the mock function
-// arguments.  However rest assured that your code is still type-safe:
-// you'll get a compiler error if *arg1 doesn't support the ++
-// operator, or if the type of ++(*arg1) isn't compatible with the
-// mock function's return type, for example.
-//
-// Sometimes you'll want to parameterize the action.   For that you can use
-// another macro:
-//
-//   ACTION_P(name, param_name) { statements; }
-//
-// For example:
-//
-//   ACTION_P(Add, n) { return arg0 + n; }
-//
-// will allow you to write:
-//
-//   ...WillOnce(Add(5));
-//
-// Note that you don't need to provide the type of the parameter
-// either.  If you need to reference the type of a parameter named
-// 'foo', you can write 'foo_type'.  For example, in the body of
-// ACTION_P(Add, n) above, you can write 'n_type' to refer to the type
-// of 'n'.
-//
-// We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P10 to support
-// multi-parameter actions.
-//
-// For the purpose of typing, you can view
-//
-//   ACTION_Pk(Foo, p1, ..., pk) { ... }
-//
-// as shorthand for
-//
-//   template <typename p1_type, ..., typename pk_type>
-//   FooActionPk<p1_type, ..., pk_type> Foo(p1_type p1, ..., pk_type pk) { ... }
-//
-// In particular, you can provide the template type arguments
-// explicitly when invoking Foo(), as in Foo<long, bool>(5, false);
-// although usually you can rely on the compiler to infer the types
-// for you automatically.  You can assign the result of expression
-// Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ...,
-// pk_type>.  This can be useful when composing actions.
-//
-// You can also overload actions with different numbers of parameters:
-//
-//   ACTION_P(Plus, a) { ... }
-//   ACTION_P2(Plus, a, b) { ... }
-//
-// While it's tempting to always use the ACTION* macros when defining
-// a new action, you should also consider implementing ActionInterface
-// or using MakePolymorphicAction() instead, especially if you need to
-// use the action a lot.  While these approaches require more work,
-// they give you more control on the types of the mock function
-// arguments and the action parameters, which in general leads to
-// better compiler error messages that pay off in the long run.  They
-// also allow overloading actions based on parameter types (as opposed
-// to just based on the number of parameters).
-//
-// CAVEAT:
-//
-// ACTION*() can only be used in a namespace scope.  The reason is
-// that C++ doesn't yet allow function-local types to be used to
-// instantiate templates.  The up-coming C++0x standard will fix this.
-// Once that's done, we'll consider supporting using ACTION*() inside
-// a function.

-// Sometimes you want to give an action explicit template parameters
-// that cannot be inferred from its value parameters.  ACTION() and
-// ACTION_P*() don't support that.  ACTION_TEMPLATE() remedies that
-// and can be viewed as an extension to ACTION() and ACTION_P*().
-//
-// The syntax:
-//
-//   ACTION_TEMPLATE(ActionName,
-//                   HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
-//                   AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
-//
-// defines an action template that takes m explicit template
-// parameters and n value parameters.  name_i is the name of the i-th
-// template parameter, and kind_i specifies whether it's a typename,
-// an integral constant, or a template.  p_i is the name of the i-th
-// value parameter.
-//
-// Example:
-//
-//   // DuplicateArg<k, T>(output) converts the k-th argument of the mock
-//   // function to type T and copies it to *output.
-//   ACTION_TEMPLATE(DuplicateArg,
-//                   HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
-//                   AND_1_VALUE_PARAMS(output)) {
-//     *output = T(::testing::get<k>(args));
-//   }
-//   ...
-//     int n;
-//     EXPECT_CALL(mock, Foo(_, _))
-//         .WillOnce(DuplicateArg<1, unsigned char>(&n));
-//
-// To create an instance of an action template, write:
-//
-//   ActionName<t1, ..., t_m>(v1, ..., v_n)
-//
-// where the ts are the template arguments and the vs are the value
-// arguments.  The value argument types are inferred by the compiler.
-// If you want to explicitly specify the value argument types, you can
-// provide additional template arguments:
-//
-//   ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
-//
-// where u_i is the desired type of v_i.
-//
-// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
-// number of value parameters, but not on the number of template
-// parameters.  Without the restriction, the meaning of the following
-// is unclear:
-//
-//   OverloadedAction<int, bool>(x);
-//
-// Are we using a single-template-parameter action where 'bool' refers
-// to the type of x, or are we using a two-template-parameter action
-// where the compiler is asked to infer the type of x?
-//
-// Implementation notes:
-//
-// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
-// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
-// implementing ACTION_TEMPLATE.  The main trick we use is to create
-// new macro invocations when expanding a macro.  For example, we have
-//
-//   #define ACTION_TEMPLATE(name, template_params, value_params)
-//       ... GMOCK_INTERNAL_DECL_##template_params ...
-//
-// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
-// to expand to
-//
-//       ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
-//
-// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
-// preprocessor will continue to expand it to
-//
-//       ... typename T ...
-//
-// This technique conforms to the C++ standard and is portable.  It
-// allows us to implement action templates using O(N) code, where N is
-// the maximum number of template/value parameters supported.  Without
-// using it, we'd have to devote O(N^2) amount of code to implement all
-// combinations of m and n.

-// Various overloads for InvokeArgument<N>().
-//
-// The InvokeArgument<N>(a1, a2, ..., a_k) action invokes the N-th
-// (0-based) argument, which must be a k-ary callable, of the mock
-// function, with arguments a1, a2, ..., a_k.
-//
-// Notes:
-//
-//   1. The arguments are passed by value by default.  If you need to
-//   pass an argument by reference, wrap it inside ByRef().  For
-//   example,
-//
-//     InvokeArgument<1>(5, string("Hello"), ByRef(foo))
-//
-//   passes 5 and string("Hello") by value, and passes foo by
-//   reference.
-//
-//   2. If the callable takes an argument by reference but ByRef() is
-//   not used, it will receive the reference to a copy of the value,
-//   instead of the original value.  For example, when the 0-th
-//   argument of the mock function takes a const string&, the action
-//
-//     InvokeArgument<0>(string("Hello"))
-//
-//   makes a copy of the temporary string("Hello") object and passes a
-//   reference of the copy, instead of the original temporary object,
-//   to the callable.  This makes it easy for a user to define an
-//   InvokeArgument action from temporary values and have it performed
-//   later.

-// The ACTION* family of macros can be used in a namespace scope to
-// define custom actions easily.  The syntax:
-//
-//   ACTION(name) { statements; }
-//
-// will define an action with the given name that executes the
-// statements.  The value returned by the statements will be used as
-// the return value of the action.  Inside the statements, you can
-// refer to the K-th (0-based) argument of the mock function by
-// 'argK', and refer to its type by 'argK_type'.  For example:
-//
-//   ACTION(IncrementArg1) {
-//     arg1_type temp = arg1;
-//     return ++(*temp);
-//   }
-//
-// allows you to write
-//
-//   ...WillOnce(IncrementArg1());
-//
-// You can also refer to the entire argument tuple and its type by
-// 'args' and 'args_type', and refer to the mock function type and its
-// return type by 'function_type' and 'return_type'.
-//
-// Note that you don't need to specify the types of the mock function
-// arguments.  However rest assured that your code is still type-safe:
-// you'll get a compiler error if *arg1 doesn't support the ++
-// operator, or if the type of ++(*arg1) isn't compatible with the
-// mock function's return type, for example.
-//
-// Sometimes you'll want to parameterize the action.   For that you can use
-// another macro:
-//
-//   ACTION_P(name, param_name) { statements; }
-//
-// For example:
-//
-//   ACTION_P(Add, n) { return arg0 + n; }
-//
-// will allow you to write:
-//
-//   ...WillOnce(Add(5));
-//
-// Note that you don't need to provide the type of the parameter
-// either.  If you need to reference the type of a parameter named
-// 'foo', you can write 'foo_type'.  For example, in the body of
-// ACTION_P(Add, n) above, you can write 'n_type' to refer to the type
-// of 'n'.
-//
-// We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P$n to support
-// multi-parameter actions.
-//
-// For the purpose of typing, you can view
-//
-//   ACTION_Pk(Foo, p1, ..., pk) { ... }
-//
-// as shorthand for
-//
-//   template <typename p1_type, ..., typename pk_type>
-//   FooActionPk<p1_type, ..., pk_type> Foo(p1_type p1, ..., pk_type pk) { ... }
-//
-// In particular, you can provide the template type arguments
-// explicitly when invoking Foo(), as in Foo<long, bool>(5, false);
-// although usually you can rely on the compiler to infer the types
-// for you automatically.  You can assign the result of expression
-// Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ...,
-// pk_type>.  This can be useful when composing actions.
-//
-// You can also overload actions with different numbers of parameters:
-//
-//   ACTION_P(Plus, a) { ... }
-//   ACTION_P2(Plus, a, b) { ... }
-//
-// While it's tempting to always use the ACTION* macros when defining
-// a new action, you should also consider implementing ActionInterface
-// or using MakePolymorphicAction() instead, especially if you need to
-// use the action a lot.  While these approaches require more work,
-// they give you more control on the types of the mock function
-// arguments and the action parameters, which in general leads to
-// better compiler error messages that pay off in the long run.  They
-// also allow overloading actions based on parameter types (as opposed
-// to just based on the number of parameters).
-//
-// CAVEAT:
-//
-// ACTION*() can only be used in a namespace scope.  The reason is
-// that C++ doesn't yet allow function-local types to be used to
-// instantiate templates.  The up-coming C++0x standard will fix this.
-// Once that's done, we'll consider supporting using ACTION*() inside
-// a function.

-// that cannot be inferred from its value parameters.  ACTION() and
-// ACTION_P*() don't support that.  ACTION_TEMPLATE() remedies that
-// and can be viewed as an extension to ACTION() and ACTION_P*().
-//
-// The syntax:
-//
-//   ACTION_TEMPLATE(ActionName,
-//                   HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),

-//
-// defines an action template that takes m explicit template
-// parameters and n value parameters.  name_i is the name of the i-th
-// template parameter, and kind_i specifies whether it's a typename,
-// an integral constant, or a template.  p_i is the name of the i-th
-// value parameter.
-//
-// Example:
-//
-//   // DuplicateArg<k, T>(output) converts the k-th argument of the mock
-//   // function to type T and copies it to *output.
-//   ACTION_TEMPLATE(DuplicateArg,
-//                   HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
-//                   AND_1_VALUE_PARAMS(output)) {
-//     *output = T(::testing::get<k>(args));

-//   ...
-//     int n;
-//     EXPECT_CALL(mock, Foo(_, _))
-//         .WillOnce(DuplicateArg<1, unsigned char>(&n));
-//
-// To create an instance of an action template, write:
-//
-//   ActionName<t1, ..., t_m>(v1, ..., v_n)
-//
-// where the ts are the template arguments and the vs are the value
-// arguments.  The value argument types are inferred by the compiler.
-// If you want to explicitly specify the value argument types, you can
-// provide additional template arguments:
-//
-//   ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
-//
-// where u_i is the desired type of v_i.
-//
-// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
-// number of value parameters, but not on the number of template
-// parameters.  Without the restriction, the meaning of the following
-// is unclear:
-//
-//   OverloadedAction<int, bool>(x);
-//
-// Are we using a single-template-parameter action where 'bool' refers
-// to the type of x, or are we using a two-template-parameter action
-// where the compiler is asked to infer the type of x?
-//
-// Implementation notes:
-//
-// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
-// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
-// implementing ACTION_TEMPLATE.  The main trick we use is to create
-// new macro invocations when expanding a macro.  For example, we have
-//
-//   #define ACTION_TEMPLATE(name, template_params, value_params)
-//       ... GMOCK_INTERNAL_DECL_##template_params ...
-//
-// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
-// to expand to
-//
-//       ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
-//
-// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
-// preprocessor will continue to expand it to
-//
-//       ... typename T ...
-//
-// This technique conforms to the C++ standard and is portable.  It
-// allows us to implement action templates using O(N) code, where N is
-// the maximum number of template/value parameters supported.  Without
-// using it, we'd have to devote O(N^2) amount of code to implement all
-// combinations of m and n.

-// (0-based) argument, which must be a k-ary callable, of the mock
-// function, with arguments a1, a2, ..., a_k.
-//
-// Notes:
-//
-//   1. The arguments are passed by value by default.  If you need to
-//   pass an argument by reference, wrap it inside ByRef().  For
-//   example,
-//
-//     InvokeArgument<1>(5, string("Hello"), ByRef(foo))
-//
-//   passes 5 and string("Hello") by value, and passes foo by
-//   reference.
-//
-//   2. If the callable takes an argument by reference but ByRef() is
-//   not used, it will receive the reference to a copy of the value,
-//   instead of the original value.  For example, when the 0-th
-//   argument of the mock function takes a const string&, the action
-//
-//     InvokeArgument<0>(string("Hello"))
-//
-//   makes a copy of the temporary string("Hello") object and passes a
-//   reference of the copy, instead of the original temporary object,
-//   to the callable.  This makes it easy for a user to define an
-//   InvokeArgument action from temporary values and have it performed
-//   later.

-// A MockFunction<F> class has one mock method whose type is F.  It is
-// useful when you just want your test code to emit some messages and
-// have Google Mock verify the right messages are sent (and perhaps at
-// the right times).  For example, if you are exercising code:
-//
-//   Foo(1);
-//   Foo(2);
-//   Foo(3);
-//
-// and want to verify that Foo(1) and Foo(3) both invoke
-// mock.Bar("a"), but Foo(2) doesn't invoke anything, you can write:
-//
-// TEST(FooTest, InvokesBarCorrectly) {
-//   MyMock mock;
-//   MockFunction<void(string check_point_name)> check;
-//   {
-//     InSequence s;
-//
-//     EXPECT_CALL(mock, Bar("a"));
-//     EXPECT_CALL(check, Call("1"));
-//     EXPECT_CALL(check, Call("2"));
-//     EXPECT_CALL(mock, Bar("a"));
-//   }
-//   Foo(1);
-//   check.Call("1");
-//   Foo(2);
-//   check.Call("2");
-//   Foo(3);
-// }
-//
-// The expectation spec says that the first Bar("a") must happen
-// before check point "1", the second Bar("a") must happen after check
-// point "2", and nothing should happen between the two check
-// points. The explicit check points make it easy to tell which
-// Bar("a") is called by which call to Foo().
-//
-// MockFunction<F> can also be used to exercise code that accepts
-// std::function<F> callbacks. To do so, use AsStdFunction() method
-// to create std::function proxy forwarding to original object's Call.
-// Example:
-//
-// TEST(FooTest, RunsCallbackWithBarArgument) {
-//   MockFunction<int(string)> callback;
-//   EXPECT_CALL(callback, Call("bar")).WillOnce(Return(1));
-//   Foo(callback.AsStdFunction());
-// }

-// A MockFunction<F> class has one mock method whose type is F.  It is
-// useful when you just want your test code to emit some messages and
-// have Google Mock verify the right messages are sent (and perhaps at
-// the right times).  For example, if you are exercising code:
-//
-//   Foo(1);
-//   Foo(2);
-//   Foo(3);
-//
-// and want to verify that Foo(1) and Foo(3) both invoke
-// mock.Bar("a"), but Foo(2) doesn't invoke anything, you can write:
-//
-// TEST(FooTest, InvokesBarCorrectly) {
-//   MyMock mock;
-//   MockFunction<void(string check_point_name)> check;
-//   {
-//     InSequence s;
-//
-//     EXPECT_CALL(mock, Bar("a"));
-//     EXPECT_CALL(check, Call("1"));
-//     EXPECT_CALL(check, Call("2"));
-//     EXPECT_CALL(mock, Bar("a"));
-//   }
-//   Foo(1);
-//   check.Call("1");
-//   Foo(2);
-//   check.Call("2");
-//   Foo(3);
-// }
-//
-// The expectation spec says that the first Bar("a") must happen
-// before check point "1", the second Bar("a") must happen after check
-// point "2", and nothing should happen between the two check
-// points. The explicit check points make it easy to tell which
-// Bar("a") is called by which call to Foo().
-//
-// MockFunction<F> can also be used to exercise code that accepts
-// std::function<F> callbacks. To do so, use AsStdFunction() method
-// to create std::function proxy forwarding to original object's Call.
-// Example:
-//
-// TEST(FooTest, RunsCallbackWithBarArgument) {
-//   MockFunction<int(string)> callback;
-//   EXPECT_CALL(callback, Call("bar")).WillOnce(Return(1));
-//   Foo(callback.AsStdFunction());

-// The MATCHER* family of macros can be used in a namespace scope to
-// define custom matchers easily.
-//
-// Basic Usage
-// ===========
-//
-// The syntax
-//
-//   MATCHER(name, description_string) { statements; }
-//
-// defines a matcher with the given name that executes the statements,
-// which must return a bool to indicate if the match succeeds.  Inside
-// the statements, you can refer to the value being matched by 'arg',
-// and refer to its type by 'arg_type'.
-//
-// The description string documents what the matcher does, and is used
-// to generate the failure message when the match fails.  Since a
-// MATCHER() is usually defined in a header file shared by multiple
-// C++ source files, we require the description to be a C-string
-// literal to avoid possible side effects.  It can be empty, in which
-// case we'll use the sequence of words in the matcher name as the
-// description.
-//
-// For example:
-//
-//   MATCHER(IsEven, "") { return (arg % 2) == 0; }
-//
-// allows you to write
-//
-//   // Expects mock_foo.Bar(n) to be called where n is even.
-//   EXPECT_CALL(mock_foo, Bar(IsEven()));
-//
-// or,
-//
-//   // Verifies that the value of some_expression is even.
-//   EXPECT_THAT(some_expression, IsEven());
-//
-// If the above assertion fails, it will print something like:
-//
-//   Value of: some_expression
-//   Expected: is even
-//     Actual: 7
-//
-// where the description "is even" is automatically calculated from the
-// matcher name IsEven.
-//
-// Argument Type
-// =============
-//
-// Note that the type of the value being matched (arg_type) is
-// determined by the context in which you use the matcher and is
-// supplied to you by the compiler, so you don't need to worry about
-// declaring it (nor can you).  This allows the matcher to be
-// polymorphic.  For example, IsEven() can be used to match any type
-// where the value of "(arg % 2) == 0" can be implicitly converted to
-// a bool.  In the "Bar(IsEven())" example above, if method Bar()
-// takes an int, 'arg_type' will be int; if it takes an unsigned long,
-// 'arg_type' will be unsigned long; and so on.
-//
-// Parameterizing Matchers
-// =======================
-//
-// Sometimes you'll want to parameterize the matcher.  For that you
-// can use another macro:
-//
-//   MATCHER_P(name, param_name, description_string) { statements; }
-//
-// For example:
-//
-//   MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
-//
-// will allow you to write:
-//
-//   EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
-//
-// which may lead to this message (assuming n is 10):
-//
-//   Value of: Blah("a")
-//   Expected: has absolute value 10
-//     Actual: -9
-//
-// Note that both the matcher description and its parameter are
-// printed, making the message human-friendly.
-//
-// In the matcher definition body, you can write 'foo_type' to
-// reference the type of a parameter named 'foo'.  For example, in the
-// body of MATCHER_P(HasAbsoluteValue, value) above, you can write
-// 'value_type' to refer to the type of 'value'.
-//
-// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P10 to
-// support multi-parameter matchers.
-//
-// Describing Parameterized Matchers
-// =================================
-//
-// The last argument to MATCHER*() is a string-typed expression.  The
-// expression can reference all of the matcher's parameters and a
-// special bool-typed variable named 'negation'.  When 'negation' is
-// false, the expression should evaluate to the matcher's description;
-// otherwise it should evaluate to the description of the negation of
-// the matcher.  For example,
-//
-//   using testing::PrintToString;
-//
-//   MATCHER_P2(InClosedRange, low, hi,
-//       std::string(negation ? "is not" : "is") + " in range [" +
-//       PrintToString(low) + ", " + PrintToString(hi) + "]") {
-//     return low <= arg && arg <= hi;
-//   }
-//   ...
-//   EXPECT_THAT(3, InClosedRange(4, 6));
-//   EXPECT_THAT(3, Not(InClosedRange(2, 4)));
-//
-// would generate two failures that contain the text:
-//
-//   Expected: is in range [4, 6]
-//   ...
-//   Expected: is not in range [2, 4]
-//
-// If you specify "" as the description, the failure message will
-// contain the sequence of words in the matcher name followed by the
-// parameter values printed as a tuple.  For example,
-//
-//   MATCHER_P2(InClosedRange, low, hi, "") { ... }
-//   ...
-//   EXPECT_THAT(3, InClosedRange(4, 6));
-//   EXPECT_THAT(3, Not(InClosedRange(2, 4)));
-//
-// would generate two failures that contain the text:
-//
-//   Expected: in closed range (4, 6)
-//   ...
-//   Expected: not (in closed range (2, 4))
-//
-// Types of Matcher Parameters
-// ===========================
-//
-// For the purpose of typing, you can view
-//
-//   MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
-//
-// as shorthand for
-//
-//   template <typename p1_type, ..., typename pk_type>
-//   FooMatcherPk<p1_type, ..., pk_type>
-//   Foo(p1_type p1, ..., pk_type pk) { ... }
-//
-// When you write Foo(v1, ..., vk), the compiler infers the types of
-// the parameters v1, ..., and vk for you.  If you are not happy with
-// the result of the type inference, you can specify the types by
-// explicitly instantiating the template, as in Foo<long, bool>(5,
-// false).  As said earlier, you don't get to (or need to) specify
-// 'arg_type' as that's determined by the context in which the matcher
-// is used.  You can assign the result of expression Foo(p1, ..., pk)
-// to a variable of type FooMatcherPk<p1_type, ..., pk_type>.  This
-// can be useful when composing matchers.
-//
-// While you can instantiate a matcher template with reference types,
-// passing the parameters by pointer usually makes your code more
-// readable.  If, however, you still want to pass a parameter by
-// reference, be aware that in the failure message generated by the
-// matcher you will see the value of the referenced object but not its
-// address.
-//
-// Explaining Match Results
-// ========================
-//
-// Sometimes the matcher description alone isn't enough to explain why
-// the match has failed or succeeded.  For example, when expecting a
-// long string, it can be very helpful to also print the diff between
-// the expected string and the actual one.  To achieve that, you can
-// optionally stream additional information to a special variable
-// named result_listener, whose type is a pointer to class
-// MatchResultListener:
-//
-//   MATCHER_P(EqualsLongString, str, "") {
-//     if (arg == str) return true;
-//
-//     *result_listener << "the difference: "
-///                     << DiffStrings(str, arg);
-//     return false;
-//   }
-//
-// Overloading Matchers
-// ====================
-//
-// You can overload matchers with different numbers of parameters:
-//
-//   MATCHER_P(Blah, a, description_string1) { ... }
-//   MATCHER_P2(Blah, a, b, description_string2) { ... }
-//
-// Caveats
-// =======
-//
-// When defining a new matcher, you should also consider implementing
-// MatcherInterface or using MakePolymorphicMatcher().  These
-// approaches require more work than the MATCHER* macros, but also
-// give you more control on the types of the value being matched and
-// the matcher parameters, which may leads to better compiler error
-// messages when the matcher is used wrong.  They also allow
-// overloading matchers based on parameter types (as opposed to just
-// based on the number of parameters).
-//
-// MATCHER*() can only be used in a namespace scope.  The reason is
-// that C++ doesn't yet allow function-local types to be used to
-// instantiate templates.  The up-coming C++0x standard will fix this.
-// Once that's done, we'll consider supporting using MATCHER*() inside
-// a function.
-//

-
-
-// The MATCHER* family of macros can be used in a namespace scope to
-// define custom matchers easily.
-//
-// Basic Usage
-// ===========
-//
-// The syntax
-//
-//   MATCHER(name, description_string) { statements; }
-//
-// defines a matcher with the given name that executes the statements,
-// which must return a bool to indicate if the match succeeds.  Inside
-// the statements, you can refer to the value being matched by 'arg',
-// and refer to its type by 'arg_type'.
-//
-// The description string documents what the matcher does, and is used
-// to generate the failure message when the match fails.  Since a
-// MATCHER() is usually defined in a header file shared by multiple
-// C++ source files, we require the description to be a C-string
-// literal to avoid possible side effects.  It can be empty, in which
-// case we'll use the sequence of words in the matcher name as the
-// description.
-//
-// For example:
-//
-//   MATCHER(IsEven, "") { return (arg % 2) == 0; }
-//
-// allows you to write
-//
-//   // Expects mock_foo.Bar(n) to be called where n is even.
-//   EXPECT_CALL(mock_foo, Bar(IsEven()));
-//
-// or,
-//
-//   // Verifies that the value of some_expression is even.
-//   EXPECT_THAT(some_expression, IsEven());
-//
-// If the above assertion fails, it will print something like:
-//
-//   Value of: some_expression
-//   Expected: is even
-//     Actual: 7
-//
-// where the description "is even" is automatically calculated from the
-// matcher name IsEven.
-//
-// Argument Type
-// =============
-//
-// Note that the type of the value being matched (arg_type) is
-// determined by the context in which you use the matcher and is
-// supplied to you by the compiler, so you don't need to worry about
-// declaring it (nor can you).  This allows the matcher to be
-// polymorphic.  For example, IsEven() can be used to match any type
-// where the value of "(arg % 2) == 0" can be implicitly converted to
-// a bool.  In the "Bar(IsEven())" example above, if method Bar()
-// takes an int, 'arg_type' will be int; if it takes an unsigned long,
-// 'arg_type' will be unsigned long; and so on.
-//
-// Parameterizing Matchers
-// =======================
-//
-// Sometimes you'll want to parameterize the matcher.  For that you
-// can use another macro:
-//
-//   MATCHER_P(name, param_name, description_string) { statements; }
-//
-// For example:
-//
-//   MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
-//
-// will allow you to write:
-//
-//   EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
-//
-// which may lead to this message (assuming n is 10):
-//
-//   Value of: Blah("a")
-//   Expected: has absolute value 10
-//     Actual: -9
-//
-// Note that both the matcher description and its parameter are
-// printed, making the message human-friendly.
-//
-// In the matcher definition body, you can write 'foo_type' to
-// reference the type of a parameter named 'foo'.  For example, in the
-// body of MATCHER_P(HasAbsoluteValue, value) above, you can write
-// 'value_type' to refer to the type of 'value'.
-//
-// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P$n to
-// support multi-parameter matchers.
-//
-// Describing Parameterized Matchers
-// =================================
-//
-// The last argument to MATCHER*() is a string-typed expression.  The
-// expression can reference all of the matcher's parameters and a
-// special bool-typed variable named 'negation'.  When 'negation' is
-// false, the expression should evaluate to the matcher's description;
-// otherwise it should evaluate to the description of the negation of
-// the matcher.  For example,
-//
-//   using testing::PrintToString;
-//
-//   MATCHER_P2(InClosedRange, low, hi,
-//       std::string(negation ? "is not" : "is") + " in range [" +
-//       PrintToString(low) + ", " + PrintToString(hi) + "]") {
-//     return low <= arg && arg <= hi;
-//   }
-//   ...
-//   EXPECT_THAT(3, InClosedRange(4, 6));
-//   EXPECT_THAT(3, Not(InClosedRange(2, 4)));
-//
-// would generate two failures that contain the text:
-//
-//   Expected: is in range [4, 6]
-//   ...
-//   Expected: is not in range [2, 4]
-//
-// If you specify "" as the description, the failure message will
-// contain the sequence of words in the matcher name followed by the
-// parameter values printed as a tuple.  For example,
-//
-//   MATCHER_P2(InClosedRange, low, hi, "") { ... }
-//   ...
-//   EXPECT_THAT(3, InClosedRange(4, 6));
-//   EXPECT_THAT(3, Not(InClosedRange(2, 4)));
-//
-// would generate two failures that contain the text:
-//
-//   Expected: in closed range (4, 6)
-//   ...
-//   Expected: not (in closed range (2, 4))
-//
-// Types of Matcher Parameters
-// ===========================
-//
-// For the purpose of typing, you can view
-//
-//   MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
-//
-// as shorthand for
-//
-//   template <typename p1_type, ..., typename pk_type>
-//   FooMatcherPk<p1_type, ..., pk_type>
-//   Foo(p1_type p1, ..., pk_type pk) { ... }
-//
-// When you write Foo(v1, ..., vk), the compiler infers the types of
-// the parameters v1, ..., and vk for you.  If you are not happy with
-// the result of the type inference, you can specify the types by
-// explicitly instantiating the template, as in Foo<long, bool>(5,
-// false).  As said earlier, you don't get to (or need to) specify
-// 'arg_type' as that's determined by the context in which the matcher
-// is used.  You can assign the result of expression Foo(p1, ..., pk)
-// to a variable of type FooMatcherPk<p1_type, ..., pk_type>.  This
-// can be useful when composing matchers.
-//
-// While you can instantiate a matcher template with reference types,
-// passing the parameters by pointer usually makes your code more
-// readable.  If, however, you still want to pass a parameter by
-// reference, be aware that in the failure message generated by the
-// matcher you will see the value of the referenced object but not its
-// address.
-//
-// Explaining Match Results
-// ========================
-//
-// Sometimes the matcher description alone isn't enough to explain why
-// the match has failed or succeeded.  For example, when expecting a
-// long string, it can be very helpful to also print the diff between
-// the expected string and the actual one.  To achieve that, you can
-// optionally stream additional information to a special variable
-// named result_listener, whose type is a pointer to class
-// MatchResultListener:
-//
-//   MATCHER_P(EqualsLongString, str, "") {
-//     if (arg == str) return true;
-//
-//     *result_listener << "the difference: "
-///                     << DiffStrings(str, arg);
-//     return false;
-//   }
-//
-// Overloading Matchers
-// ====================
-//
-// You can overload matchers with different numbers of parameters:
-//
-//   MATCHER_P(Blah, a, description_string1) { ... }
-//   MATCHER_P2(Blah, a, b, description_string2) { ... }
-//
-// Caveats
-// =======
-//
-// When defining a new matcher, you should also consider implementing
-// MatcherInterface or using MakePolymorphicMatcher().  These
-// approaches require more work than the MATCHER* macros, but also
-// give you more control on the types of the value being matched and
-// the matcher parameters, which may leads to better compiler error
-// messages when the matcher is used wrong.  They also allow
-// overloading matchers based on parameter types (as opposed to just
-// based on the number of parameters).
-//
-// MATCHER*() can only be used in a namespace scope.  The reason is
-// that C++ doesn't yet allow function-local types to be used to
-// instantiate templates.  The up-coming C++0x standard will fix this.
-// Once that's done, we'll consider supporting using MATCHER*() inside
-// a function.
-//

-// Implements class templates NiceMock, NaggyMock, and StrictMock.
-//
-// Given a mock class MockFoo that is created using Google Mock,
-// NiceMock<MockFoo> is a subclass of MockFoo that allows
-// uninteresting calls (i.e. calls to mock methods that have no
-// EXPECT_CALL specs), NaggyMock<MockFoo> is a subclass of MockFoo
-// that prints a warning when an uninteresting call occurs, and
-// StrictMock<MockFoo> is a subclass of MockFoo that treats all
-// uninteresting calls as errors.
-//
-// Currently a mock is naggy by default, so MockFoo and
-// NaggyMock<MockFoo> behave like the same.  However, we will soon
-// switch the default behavior of mocks to be nice, as that in general
-// leads to more maintainable tests.  When that happens, MockFoo will
-// stop behaving like NaggyMock<MockFoo> and start behaving like
-// NiceMock<MockFoo>.
-//
-// NiceMock, NaggyMock, and StrictMock "inherit" the constructors of
-// their respective base class.  Therefore you can write
-// NiceMock<MockFoo>(5, "a") to construct a nice mock where MockFoo
-// has a constructor that accepts (int, const char*), for example.
-//
-// A known limitation is that NiceMock<MockFoo>, NaggyMock<MockFoo>,
-// and StrictMock<MockFoo> only works for mock methods defined using
-// the MOCK_METHOD* family of macros DIRECTLY in the MockFoo class.
-// If a mock method is defined in a base class of MockFoo, the "nice"
-// or "strict" modifier may not affect it, depending on the compiler.
-// In particular, nesting NiceMock, NaggyMock, and StrictMock is NOT
-// supported.

-// Implements class templates NiceMock, NaggyMock, and StrictMock.
-//
-// Given a mock class MockFoo that is created using Google Mock,
-// NiceMock<MockFoo> is a subclass of MockFoo that allows
-// uninteresting calls (i.e. calls to mock methods that have no
-// EXPECT_CALL specs), NaggyMock<MockFoo> is a subclass of MockFoo
-// that prints a warning when an uninteresting call occurs, and
-// StrictMock<MockFoo> is a subclass of MockFoo that treats all
-// uninteresting calls as errors.
-//
-// Currently a mock is naggy by default, so MockFoo and
-// NaggyMock<MockFoo> behave like the same.  However, we will soon
-// switch the default behavior of mocks to be nice, as that in general
-// leads to more maintainable tests.  When that happens, MockFoo will
-// stop behaving like NaggyMock<MockFoo> and start behaving like
-// NiceMock<MockFoo>.
-//
-// NiceMock, NaggyMock, and StrictMock "inherit" the constructors of
-// their respective base class.  Therefore you can write
-// NiceMock<MockFoo>(5, "a") to construct a nice mock where MockFoo
-// has a constructor that accepts (int, const char*), for example.
-//
-// A known limitation is that NiceMock<MockFoo>, NaggyMock<MockFoo>,
-// and StrictMock<MockFoo> only works for mock methods defined using
-// the MOCK_METHOD* family of macros DIRECTLY in the MockFoo class.
-// If a mock method is defined in a base class of MockFoo, the "nice"
-// or "strict" modifier may not affect it, depending on the compiler.
-// In particular, nesting NiceMock, NaggyMock, and StrictMock is NOT
-// supported.

-// This macro supports statements both with and without parameter matchers. If

-// How this works: The mock class uses two overloads of the gmock_Method
-// expectation setter method plus an operator() overload on the MockSpec object.
-// In the matcher list form, the macro expands to:
-//
-//   // This statement:
-//   ON_CALL(mock, TwoArgsMethod(_, 45))...
-//
-//   // ...expands to:
-//   mock.gmock_TwoArgsMethod(_, 45)(WithoutMatchers(), nullptr)...
-//   |-------------v---------------||------------v-------------|
-//       invokes first overload        swallowed by operator()

-//   // ...which is essentially:
-//   mock.gmock_TwoArgsMethod(_, 45)...
-//
-// Whereas the form without a matcher list:
-//
-//   // This statement:
-//   ON_CALL(mock, TwoArgsMethod)...

-//   // ...expands to:
-//   mock.gmock_TwoArgsMethod(WithoutMatchers(), nullptr)...

-//                 invokes second overload
-//
-//   // ...which is essentially:
-//   mock.gmock_TwoArgsMethod(_, _)...
-//
-// The WithoutMatchers() argument is used to disambiguate overloads and to
-// block the caller from accidentally invoking the second overload directly. The
-// second argument is an internal type derived from the method signature. The
-// failure to disambiguate two overloads of this method in the ON_CALL statement

-"""fuse_gmock_files.py v0.1.0
-Fuses Google Mock and Google Test source code into two .h files and a .cc file.
-
-SYNOPSIS
-       fuse_gmock_files.py [GMOCK_ROOT_DIR] OUTPUT_DIR
-
-       Scans GMOCK_ROOT_DIR for Google Mock and Google Test source
-       code, assuming Google Test is in the GMOCK_ROOT_DIR/../googletest
-       directory, and generates three files:
-       OUTPUT_DIR/gtest/gtest.h, OUTPUT_DIR/gmock/gmock.h, and
-       OUTPUT_DIR/gmock-gtest-all.cc.  Then you can build your tests
-       by adding OUTPUT_DIR to the include search path and linking
-       with OUTPUT_DIR/gmock-gtest-all.cc.  These three files contain
-       everything you need to use Google Mock.  Hence you can
-       "install" Google Mock by copying them to wherever you want.
-
-       GMOCK_ROOT_DIR can be omitted and defaults to the parent
-       directory of the directory holding this script.
-
-EXAMPLES
-       ./fuse_gmock_files.py fused_gmock
-       ./fuse_gmock_files.py path/to/unpacked/gmock fused_gmock
-
-This tool is experimental.  In particular, it assumes that there is no
-conditional inclusion of Google Mock or Google Test headers.  Please
-report any problems to googlemock@googlegroups.com.  You can read
-https://github.com/google/googletest/blob/master/googlemock/docs/CookBook.md for more
-information.

-
-The Google Mock class generator is an application that is part of cppclean.
-For more information about cppclean, visit http://code.google.com/p/cppclean/
-
-The mock generator requires Python 2.3.5 or later.  If you don't have Python
-installed on your system, you will also need to install it.  You can download
-Python from:  http://www.python.org/download/releases/
-
-To use the Google Mock class generator, you need to call it
-on the command line passing the header file and class for which you want
-to generate a Google Mock class.
-
-Make sure to install the scripts somewhere in your path.  Then you can
-run the program.
-
-  gmock_gen.py header-file.h [ClassName]...
-
-If no ClassNames are specified, all classes in the file are emitted.
-
-To change the indentation from the default of 2, set INDENT in
-the environment.  For example to use an indent of 4 spaces:
-
-INDENT=4 gmock_gen.py header-file.h ClassName
-
-This version was made from SVN revision 281 in the cppclean repository.
-
-Known Limitations
------------------
-Not all code will be generated properly.  For example, when mocking templated
-classes, the template information is lost.  You will need to add the template
-information manually.
-
-Not all permutations of using multiple pointers/references will be rendered
-properly.  These will also have to be fixed manually.

-Goal:
------
-  CppClean attempts to find problems in C++ source that slow development
-  in large code bases, for example various forms of unused code.
-  Unused code can be unused functions, methods, data members, types, etc
-  to unnecessary #include directives.  Unnecessary #includes can cause
-  considerable extra compiles increasing the edit-compile-run cycle.
-
-  The project home page is:   http://code.google.com/p/cppclean/
-
-
-Features:
----------
- * Find and print C++ language constructs: classes, methods, functions, etc.
- * Find classes with virtual methods, no virtual destructor, and no bases
- * Find global/static data that are potential problems when using threads
- * Unnecessary forward class declarations
- * Unnecessary function declarations
- * Undeclared function definitions
- * (planned) Find unnecessary header files #included
-   - No direct reference to anything in the header
-   - Header is unnecessary if classes were forward declared instead
- * (planned) Source files that reference headers not directly #included,
-   ie, files that rely on a transitive #include from another header
- * (planned) Unused members (private, protected, & public) methods and data
- * (planned) Store AST in a SQL database so relationships can be queried
-
-AST is Abstract Syntax Tree, a representation of parsed source code.
-http://en.wikipedia.org/wiki/Abstract_syntax_tree
-
-
-System Requirements:
---------------------
- * Python 2.4 or later (2.3 probably works too)
- * Works on Windows (untested), Mac OS X, and Unix
-
-
-How to Run:
------------
-  For all examples, it is assumed that cppclean resides in a directory called
-  /cppclean.
-
-  To print warnings for classes with virtual methods, no virtual destructor and
-  no base classes:
-
-      /cppclean/run.sh nonvirtual_dtors.py file1.h file2.h file3.cc ...
-
-  To print all the functions defined in header file(s):
-
-      /cppclean/run.sh functions.py file1.h file2.h ...
-
-  All the commands take multiple files on the command line.  Other programs
-  include: find_warnings, headers, methods, and types.  Some other programs
-  are available, but used primarily for debugging.
-
-  run.sh is a simple wrapper that sets PYTHONPATH to /cppclean and then
-  runs the program in /cppclean/cpp/PROGRAM.py.  There is currently
-  no equivalent for Windows.  Contributions for a run.bat file
-  would be greatly appreciated.
-
-
-How to Configure:
------------------
-  You can add a siteheaders.py file in /cppclean/cpp to configure where
-  to look for other headers (typically -I options passed to a compiler).
-  Currently two values are supported:  _TRANSITIVE and GetIncludeDirs.
-  _TRANSITIVE should be set to a boolean value (True or False) indicating
-  whether to transitively process all header files.  The default is False.
-
-  GetIncludeDirs is a function that takes a single argument and returns
-  a sequence of directories to include.  This can be a generator or
-  return a static list.
-
-      def GetIncludeDirs(filename):
-          return ['/some/path/with/other/headers']
-
-      # Here is a more complicated example.
-      def GetIncludeDirs(filename):
-          yield '/path1'
-          yield os.path.join('/path2', os.path.dirname(filename))
-          yield '/path3'
-
-
-How to Test:
-------------
-  For all examples, it is assumed that cppclean resides in a directory called
-  /cppclean.  The tests require
-
-  cd /cppclean
-  make test
-  # To generate expected results after a change:
-  make expected
-
-
-Current Status:
----------------
-  The parser works pretty well for header files, parsing about 99% of Google's
-  header files.  Anything which inspects structure of C++ source files should
-  work reasonably well.  Function bodies are not transformed to an AST,
-  but left as tokens.  Much work is still needed on finding unused header files
-  and storing an AST in a database.
-
-
-Non-goals:
-----------
- * Parsing all valid C++ source
- * Handling invalid C++ source gracefully
- * Compiling to machine code (or anything beyond an AST)
-

-The `gmock-config' script provides access to the necessary compile and linking
-flags to connect with Google C++ Mocking Framework, both in a build prior to
-installation, and on the system proper after installation. The installation
-overrides may be issued in combination with any other queries, but will only
-affect installation queries if called on a built but not installed gmock. The
-installation queries may not be issued with any other types of queries, and
-only one installation query may be made at a time. The version queries and
-compiler flag queries may be combined as desired but not mixed. Different
-version queries are always combined with logical "and" semantics, and only the
-last of any particular query is used while all previous ones ignored. All
-versions must be specified as a sequence of numbers separated by periods.
-Compiler flag queries output the union of the sets of flags when combined.
-
- Examples:
-  gmock-config --min-version=1.0 || echo "Insufficient Google Mock version."
-
-  g++ $(gmock-config --cppflags --cxxflags) -o foo.o -c foo.cpp
-  g++ $(gmock-config --ldflags --libs) -o foo foo.o
-
-  # When using a built but not installed Google Mock:
-  g++ $(../../my_gmock_build/scripts/gmock-config ...) ...
-
-  # When using an installed Google Mock, but with installation overrides:
-  export GMOCK_PREFIX="/opt"
-  g++ $(gmock-config --libdir="/opt/lib64" ...) ...

- Help:

-  --libdir=<dir>             overrides the library installation prefix
-  --includedir=<dir>         overrides the header file installation prefix
-
- Installation Queries:
-  --prefix                   installation prefix
-  --exec-prefix              executable installation prefix
-  --libdir                   library installation directory
-  --includedir               header file installation directory
-  --version                  the version of the Google Mock installation
-
- Version Queries:
-  --min-version=VERSION      return 0 if the version is at least VERSION
-  --exact-version=VERSION    return 0 if the version is exactly VERSION
-  --max-version=VERSION      return 0 if the version is at most VERSION
-
- Compilation Flag Queries:
-  --cppflags                 compile flags specific to the C-like preprocessors
-  --cxxflags                 compile flags appropriate for C++ programs

-// FindMaxBipartiteMatching and its helper class.
-//
-// Uses the well-known Ford-Fulkerson max flow method to find a maximum
-// bipartite matching. Flow is considered to be from left to right.
-// There is an implicit source node that is connected to all of the left
-// nodes, and an implicit sink node that is connected to all of the
-// right nodes. All edges have unit capacity.
-//
-// Neither the flow graph nor the residual flow graph are represented
-// explicitly. Instead, they are implied by the information in 'graph' and
-// a vector<int> called 'left_' whose elements are initialized to the
-// value kUnused. This represents the initial state of the algorithm,
-// where the flow graph is empty, and the residual flow graph has the
-// following edges:
-//   - An edge from source to each left_ node
-//   - An edge from each right_ node to sink
-//   - An edge from each left_ node to each right_ node, if the
-//     corresponding edge exists in 'graph'.
-//
-// When the TryAugment() method adds a flow, it sets left_[l] = r for some
-// nodes l and r. This induces the following changes:
-//   - The edges (source, l), (l, r), and (r, sink) are added to the
-//     flow graph.
-//   - The same three edges are removed from the residual flow graph.
-//   - The reverse edges (l, source), (r, l), and (sink, r) are added
-//     to the residual flow graph, which is a directional graph
-//     representing unused flow capacity.
-//
-// When the method augments a flow (moving left_[l] from some r1 to some
-// other r2), this can be thought of as "undoing" the above steps with
-// respect to r1 and "redoing" them with respect to r2.
-//
-// It bears repeating that the flow graph and residual flow graph are
-// never represented explicitly, but can be derived by looking at the
-// information in 'graph' and in left_.
-//
-// As an optimization, there is a second vector<int> called right_ which
-// does not provide any new information. Instead, it enables more
-// efficient queries about edges entering or leaving the right-side nodes
-// of the flow or residual flow graphs. The following invariants are
-// maintained:
-//
-// left[l] == kUnused or right[left[l]] == l
-// right[r] == kUnused or left[right[r]] == r

-// This file tests that:
-// a. A header file defining a mock class can be included in multiple
-//    translation units without causing a link error.
-// b. Actions and matchers can be instantiated with identical template
-//    arguments in different translation units without causing link

-//    The following constructs are currently tested:
-//    Actions:
-//      Return()
-//      Return(value)
-//      ReturnNull
-//      ReturnRef
-//      Assign
-//      SetArgPointee
-//      SetArrayArgument
-//      SetErrnoAndReturn
-//      Invoke(function)
-//      Invoke(object, method)
-//      InvokeWithoutArgs(function)
-//      InvokeWithoutArgs(object, method)

-//      Eq
-//      Gt, Lt, Ge, Le, Ne

-//      MatcherCast<T>
-//
-//  Please note: this test does not verify the functioning of these
-//  constructs, only that the programs using them will link successfully.
-//
-// Implementation note:
-// This test requires identical definitions of Interface and Mock to be
-// included in different translation units.  We achieve this by writing
-// them in this header and #including it in gmock_link_test.cc and
-// gmock_link2_test.cc.  Because the symbols generated by the compiler for
-// those constructs must be identical in both translation units,
-// definitions of Interface and Mock tests MUST be kept in the SAME
-// NON-ANONYMOUS namespace in this file.  The test fixture class LinkTest
-// is defined as LinkTest1 in gmock_link_test.cc and as LinkTest2 in
-// gmock_link2_test.cc to avoid producing linker errors.

-ERROR: 3 leaked mock objects found at program exit. Expectations on a mock object is verified when the object is destructed. Leaking a mock means that its expectations aren't verified, which is usually a test bug. If you really intend to leak a mock, you can suppress this error using testing::Mock::AllowLeak(mock_object), or you may use a fake or stub instead of a mock.

-Changes for 1.7.0:
-
-* New feature: death tests are supported on OpenBSD and in iOS
-  simulator now.
-* New feature: Google Test now implements a protocol to allow
-  a test runner to detect that a test program has exited
-  prematurely and report it as a failure (before it would be
-  falsely reported as a success if the exit code is 0).
-* New feature: Test::RecordProperty() can now be used outside of the
-  lifespan of a test method, in which case it will be attributed to
-  the current test case or the test program in the XML report.
-* New feature (potentially breaking): --gtest_list_tests now prints
-  the type parameters and value parameters for each test.
-* Improvement: char pointers and char arrays are now escaped properly
-  in failure messages.
-* Improvement: failure summary in XML reports now includes file and
-  line information.
-* Improvement: the <testsuites> XML element now has a timestamp attribute.
-* Improvement: When --gtest_filter is specified, XML report now doesn't
-  contain information about tests that are filtered out.
-* Fixed the bug where long --gtest_filter flag values are truncated in
-  death tests.
-* Potentially breaking change: RUN_ALL_TESTS() is now implemented as a
-  function instead of a macro in order to work better with Clang.
-* Compatibility fixes with C++ 11 and various platforms.
-* Bug/warning fixes.
-
-Changes for 1.6.0:
-
-* New feature: ADD_FAILURE_AT() for reporting a test failure at the
-  given source location -- useful for writing testing utilities.
-* New feature: the universal value printer is moved from Google Mock
-  to Google Test.
-* New feature: type parameters and value parameters are reported in
-  the XML report now.
-* A gtest_disable_pthreads CMake option.
-* Colored output works in GNU Screen sessions now.
-* Parameters of value-parameterized tests are now printed in the
-  textual output.
-* Failures from ad hoc test assertions run before RUN_ALL_TESTS() are
-  now correctly reported.
-* Arguments of ASSERT_XY and EXPECT_XY no longer need to support << to
-  ostream.
-* More complete handling of exceptions.
-* GTEST_ASSERT_XY can be used instead of ASSERT_XY in case the latter
-  name is already used by another library.
-* --gtest_catch_exceptions is now true by default, allowing a test
-  program to continue after an exception is thrown.
-* Value-parameterized test fixtures can now derive from Test and
-  WithParamInterface<T> separately, easing conversion of legacy tests.
-* Death test messages are clearly marked to make them more
-  distinguishable from other messages.
-* Compatibility fixes for Android, Google Native Client, MinGW, HP UX,
-  PowerPC, Lucid autotools, libCStd, Sun C++, Borland C++ Builder (Code Gear),
-  IBM XL C++ (Visual Age C++), and C++0x.
-* Bug fixes and implementation clean-ups.
-* Potentially incompatible changes: disables the harmful 'make install'
-  command in autotools.
-
-Changes for 1.5.0:
-
- * New feature: assertions can be safely called in multiple threads
-   where the pthreads library is available.
- * New feature: predicates used inside EXPECT_TRUE() and friends
-   can now generate custom failure messages.
- * New feature: Google Test can now be compiled as a DLL.
- * New feature: fused source files are included.
- * New feature: prints help when encountering unrecognized Google Test flags.
- * Experimental feature: CMake build script (requires CMake 2.6.4+).
- * Experimental feature: the Pump script for meta programming.
- * double values streamed to an assertion are printed with enough precision
-   to differentiate any two different values.
- * Google Test now works on Solaris and AIX.
- * Build and test script improvements.
- * Bug fixes and implementation clean-ups.
-
- Potentially breaking changes:
-
- * Stopped supporting VC++ 7.1 with exceptions disabled.
- * Dropped support for 'make install'.
-
-Changes for 1.4.0:
-
- * New feature: the event listener API
- * New feature: test shuffling
- * New feature: the XML report format is closer to junitreport and can
-   be parsed by Hudson now.
- * New feature: when a test runs under Visual Studio, its failures are
-   integrated in the IDE.
- * New feature: /MD(d) versions of VC++ projects.
- * New feature: elapsed time for the tests is printed by default.
- * New feature: comes with a TR1 tuple implementation such that Boost
-   is no longer needed for Combine().
- * New feature: EXPECT_DEATH_IF_SUPPORTED macro and friends.
- * New feature: the Xcode project can now produce static gtest
-   libraries in addition to a framework.
- * Compatibility fixes for Solaris, Cygwin, minGW, Windows Mobile,
-   Symbian, gcc, and C++Builder.
- * Bug fixes and implementation clean-ups.
-
-Changes for 1.3.0:
-
- * New feature: death tests on Windows, Cygwin, and Mac.
- * New feature: ability to use Google Test assertions in other testing
-   frameworks.
- * New feature: ability to run disabled test via
-   --gtest_also_run_disabled_tests.
- * New feature: the --help flag for printing the usage.
- * New feature: access to Google Test flag values in user code.
- * New feature: a script that packs Google Test into one .h and one
-   .cc file for easy deployment.
- * New feature: support for distributing test functions to multiple
-   machines (requires support from the test runner).
- * Bug fixes and implementation clean-ups.
-
-Changes for 1.2.1:
-
- * Compatibility fixes for Linux IA-64 and IBM z/OS.
- * Added support for using Boost and other TR1 implementations.
- * Changes to the build scripts to support upcoming release of Google C++
-   Mocking Framework.
- * Added Makefile to the distribution package.
- * Improved build instructions in README.
-
-Changes for 1.2.0:
-
- * New feature: value-parameterized tests.
- * New feature: the ASSERT/EXPECT_(NON)FATAL_FAILURE(_ON_ALL_THREADS)
-   macros.
- * Changed the XML report format to match JUnit/Ant's.
- * Added tests to the Xcode project.
- * Added scons/SConscript for building with SCons.
- * Added src/gtest-all.cc for building Google Test from a single file.
- * Fixed compatibility with Solaris and z/OS.
- * Enabled running Python tests on systems with python 2.3 installed,
-   e.g. Mac OS X 10.4.
- * Bug fixes.

-### Generic Build Instructions
-
-#### Setup
-
-To build Google Test and your tests that use it, you need to tell your build
-system where to find its headers and source files. The exact way to do it
-depends on which build system you use, and is usually straightforward.
-
-#### Build
-
-Suppose you put Google Test in directory `${GTEST_DIR}`. To build it, create a
-library build target (or a project as called by Visual Studio and Xcode) to
-compile
-
-    ${GTEST_DIR}/src/gtest-all.cc
-
-with `${GTEST_DIR}/include` in the system header search path and `${GTEST_DIR}`
-in the normal header search path. Assuming a Linux-like system and gcc,
-something like the following will do:
-
-    g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
-        -pthread -c ${GTEST_DIR}/src/gtest-all.cc
-    ar -rv libgtest.a gtest-all.o
-
-(We need `-pthread` as Google Test uses threads.)
-
-Next, you should compile your test source file with `${GTEST_DIR}/include` in
-the system header search path, and link it with gtest and any other necessary
-libraries:
-
-    g++ -isystem ${GTEST_DIR}/include -pthread path/to/your_test.cc libgtest.a \
-        -o your_test
-
-As an example, the make/ directory contains a Makefile that you can use to build
-Google Test on systems where GNU make is available (e.g. Linux, Mac OS X, and
-Cygwin). It doesn't try to build Google Test's own tests. Instead, it just
-builds the Google Test library and a sample test. You can use it as a starting
-point for your own build script.
-
-If the default settings are correct for your environment, the following commands
-should succeed:
-
-    cd ${GTEST_DIR}/make
-    make
-    ./sample1_unittest
-
-If you see errors, try to tweak the contents of `make/Makefile` to make them go
-away. There are instructions in `make/Makefile` on how to do it.
-
-### Using CMake
-
-Google Test comes with a CMake build script (
-[CMakeLists.txt](https://github.com/google/googletest/blob/master/CMakeLists.txt))
-that can be used on a wide range of platforms ("C" stands for cross-platform.).
-If you don't have CMake installed already, you can download it for free from
-<http://www.cmake.org/>.
-
-CMake works by generating native makefiles or build projects that can be used in
-the compiler environment of your choice. You can either build Google Test as a
-standalone project or it can be incorporated into an existing CMake build for
-another project.
-
-#### Standalone CMake Project
-
-When building Google Test as a standalone project, the typical workflow starts
-with:
-
-    mkdir mybuild       # Create a directory to hold the build output.
-    cd mybuild
-    cmake ${GTEST_DIR}  # Generate native build scripts.
-
-If you want to build Google Test's samples, you should replace the last command
-with
-
-    cmake -Dgtest_build_samples=ON ${GTEST_DIR}
-
-If you are on a \*nix system, you should now see a Makefile in the current
-directory. Just type 'make' to build gtest.
-
-If you use Windows and have Visual Studio installed, a `gtest.sln` file and
-several `.vcproj` files will be created. You can then build them using Visual
-Studio.
-
-On Mac OS X with Xcode installed, a `.xcodeproj` file will be generated.
-
-#### Incorporating Into An Existing CMake Project
-
-If you want to use gtest in a project which already uses CMake, then a more
-robust and flexible approach is to build gtest as part of that project directly.
-This is done by making the GoogleTest source code available to the main build
-and adding it using CMake's `add_subdirectory()` command. This has the
-significant advantage that the same compiler and linker settings are used
-between gtest and the rest of your project, so issues associated with using
-incompatible libraries (eg debug/release), etc. are avoided. This is
-particularly useful on Windows. Making GoogleTest's source code available to the
-main build can be done a few different ways:
-
-*   Download the GoogleTest source code manually and place it at a known
-    location. This is the least flexible approach and can make it more difficult
-    to use with continuous integration systems, etc.
-*   Embed the GoogleTest source code as a direct copy in the main project's
-    source tree. This is often the simplest approach, but is also the hardest to
-    keep up to date. Some organizations may not permit this method.
-*   Add GoogleTest as a git submodule or equivalent. This may not always be
-    possible or appropriate. Git submodules, for example, have their own set of
-    advantages and drawbacks.
-*   Use CMake to download GoogleTest as part of the build's configure step. This
-    is just a little more complex, but doesn't have the limitations of the other
-    methods.
-
-The last of the above methods is implemented with a small piece of CMake code in
-a separate file (e.g. `CMakeLists.txt.in`) which is copied to the build area and
-then invoked as a sub-build _during the CMake stage_. That directory is then
-pulled into the main build with `add_subdirectory()`. For example:
-
-New file `CMakeLists.txt.in`:
-
-    cmake_minimum_required(VERSION 2.8.2)
-
-    project(googletest-download NONE)
-
-    include(ExternalProject)
-    ExternalProject_Add(googletest
-      GIT_REPOSITORY    https://github.com/google/googletest.git
-      GIT_TAG           master
-      SOURCE_DIR        "${CMAKE_BINARY_DIR}/googletest-src"
-      BINARY_DIR        "${CMAKE_BINARY_DIR}/googletest-build"
-      CONFIGURE_COMMAND ""
-      BUILD_COMMAND     ""
-      INSTALL_COMMAND   ""
-      TEST_COMMAND      ""
-    )
-
-Existing build's `CMakeLists.txt`:
-
-    # Download and unpack googletest at configure time
-    configure_file(CMakeLists.txt.in googletest-download/CMakeLists.txt)
-    execute_process(COMMAND ${CMAKE_COMMAND} -G "${CMAKE_GENERATOR}" .
-      RESULT_VARIABLE result
-      WORKING_DIRECTORY ${CMAKE_BINARY_DIR}/googletest-download )
-    if(result)
-      message(FATAL_ERROR "CMake step for googletest failed: ${result}")
-    endif()
-    execute_process(COMMAND ${CMAKE_COMMAND} --build .
-      RESULT_VARIABLE result
-      WORKING_DIRECTORY ${CMAKE_BINARY_DIR}/googletest-download )
-    if(result)
-      message(FATAL_ERROR "Build step for googletest failed: ${result}")
-    endif()
-
-    # Prevent overriding the parent project's compiler/linker
-    # settings on Windows
-    set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
-
-    # Add googletest directly to our build. This defines
-    # the gtest and gtest_main targets.
-    add_subdirectory(${CMAKE_BINARY_DIR}/googletest-src
-                     ${CMAKE_BINARY_DIR}/googletest-build
-                     EXCLUDE_FROM_ALL)
-
-    # The gtest/gtest_main targets carry header search path
-    # dependencies automatically when using CMake 2.8.11 or
-    # later. Otherwise we have to add them here ourselves.
-    if (CMAKE_VERSION VERSION_LESS 2.8.11)
-      include_directories("${gtest_SOURCE_DIR}/include")
-    endif()
-
-    # Now simply link against gtest or gtest_main as needed. Eg
-    add_executable(example example.cpp)
-    target_link_libraries(example gtest_main)
-    add_test(NAME example_test COMMAND example)
-
-Note that this approach requires CMake 2.8.2 or later due to its use of the
-`ExternalProject_Add()` command. The above technique is discussed in more detail
-in [this separate article](http://crascit.com/2015/07/25/cmake-gtest/) which
-also contains a link to a fully generalized implementation of the technique.
-
-##### Visual Studio Dynamic vs Static Runtimes
-
-By default, new Visual Studio projects link the C runtimes dynamically but
-Google Test links them statically. This will generate an error that looks
-something like the following: gtest.lib(gtest-all.obj) : error LNK2038: mismatch
-detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value
-'MDd_DynamicDebug' in main.obj
-
-Google Test already has a CMake option for this: `gtest_force_shared_crt`
-
-Enabling this option will make gtest link the runtimes dynamically too, and
-match the project in which it is included.
-
-### Legacy Build Scripts
-
-Before settling on CMake, we have been providing hand-maintained build
-projects/scripts for Visual Studio, Xcode, and Autotools. While we continue to
-provide them for convenience, they are not actively maintained any more. We
-highly recommend that you follow the instructions in the above sections to
-integrate Google Test with your existing build system.
-
-If you still need to use the legacy build scripts, here's how:
-
-The msvc\ folder contains two solutions with Visual C++ projects. Open the
-`gtest.sln` or `gtest-md.sln` file using Visual Studio, and you are ready to
-build Google Test the same way you build any Visual Studio project. Files that
-have names ending with -md use DLL versions of Microsoft runtime libraries (the
-/MD or the /MDd compiler option). Files without that suffix use static versions
-of the runtime libraries (the /MT or the /MTd option). Please note that one must
-use the same option to compile both gtest and the test code. If you use Visual
-Studio 2005 or above, we recommend the -md version as /MD is the default for new
-projects in these versions of Visual Studio.
-
-On Mac OS X, open the `gtest.xcodeproj` in the `xcode/` folder using Xcode.
-Build the "gtest" target. The universal binary framework will end up in your
-selected build directory (selected in the Xcode "Preferences..." -> "Building"
-pane and defaults to xcode/build). Alternatively, at the command line, enter:
-
-    xcodebuild
-
-This will build the "Release" configuration of gtest.framework in your default
-build location. See the "xcodebuild" man page for more information about
-building different configurations and building in different locations.
-
-If you wish to use the Google Test Xcode project with Xcode 4.x and above, you
-need to either:
-
-*   update the SDK configuration options in xcode/Config/General.xconfig.
-    Comment options `SDKROOT`, `MACOS_DEPLOYMENT_TARGET`, and `GCC_VERSION`. If
-    you choose this route you lose the ability to target earlier versions of
-    MacOS X.
-*   Install an SDK for an earlier version. This doesn't appear to be supported
-    by Apple, but has been reported to work
-    (http://stackoverflow.com/questions/5378518).
-
-### Tweaking Google Test
-
-Google Test can be used in diverse environments. The default configuration may
-not work (or may not work well) out of the box in some environments. However,
-you can easily tweak Google Test by defining control macros on the compiler
-command line. Generally, these macros are named like `GTEST_XYZ` and you define
-them to either 1 or 0 to enable or disable a certain feature.
-
-We list the most frequently used macros below. For a complete list, see file
-[include/gtest/internal/gtest-port.h](https://github.com/google/googletest/blob/master/include/gtest/internal/gtest-port.h).
-
-### Choosing a TR1 Tuple Library
-
-Some Google Test features require the C++ Technical Report 1 (TR1) tuple
-library, which is not yet available with all compilers. The good news is that
-Google Test implements a subset of TR1 tuple that's enough for its own need, and
-will automatically use this when the compiler doesn't provide TR1 tuple.
-
-Usually you don't need to care about which tuple library Google Test uses.
-However, if your project already uses TR1 tuple, you need to tell Google Test to
-use the same TR1 tuple library the rest of your project uses, or the two tuple
-implementations will clash. To do that, add
-
-    -DGTEST_USE_OWN_TR1_TUPLE=0
-
-to the compiler flags while compiling Google Test and your tests. If you want to
-force Google Test to use its own tuple library, just add
-
-    -DGTEST_USE_OWN_TR1_TUPLE=1
-
-to the compiler flags instead.
-
-If you don't want Google Test to use tuple at all, add
-
-    -DGTEST_HAS_TR1_TUPLE=0
-
-and all features using tuple will be disabled.
-
-### Multi-threaded Tests
-
-Google Test is thread-safe where the pthread library is available. After
-`#include "gtest/gtest.h"`, you can check the `GTEST_IS_THREADSAFE` macro to see
-whether this is the case (yes if the macro is `#defined` to 1, no if it's
-undefined.).
-
-If Google Test doesn't correctly detect whether pthread is available in your
-environment, you can force it with
-
-    -DGTEST_HAS_PTHREAD=1
-
-or
-
-    -DGTEST_HAS_PTHREAD=0
-
-When Google Test uses pthread, you may need to add flags to your compiler and/or
-linker to select the pthread library, or you'll get link errors. If you use the
-CMake script or the deprecated Autotools script, this is taken care of for you.
-If you use your own build script, you'll need to read your compiler and linker's
-manual to figure out what flags to add.
-
-### As a Shared Library (DLL)
-
-Google Test is compact, so most users can build and link it as a static library
-for the simplicity. You can choose to use Google Test as a shared library (known
-as a DLL on Windows) if you prefer.
-
-To compile *gtest* as a shared library, add
-
-    -DGTEST_CREATE_SHARED_LIBRARY=1
-
-to the compiler flags. You'll also need to tell the linker to produce a shared
-library instead - consult your linker's manual for how to do it.
-
-To compile your *tests* that use the gtest shared library, add
-
-    -DGTEST_LINKED_AS_SHARED_LIBRARY=1
-
-to the compiler flags.
-
-Note: while the above steps aren't technically necessary today when using some
-compilers (e.g. GCC), they may become necessary in the future, if we decide to
-improve the speed of loading the library (see
-<http://gcc.gnu.org/wiki/Visibility> for details). Therefore you are recommended
-to always add the above flags when using Google Test as a shared library.
-Otherwise a future release of Google Test may break your build script.
-
-### Avoiding Macro Name Clashes
-
-In C++, macros don't obey namespaces. Therefore two libraries that both define a
-macro of the same name will clash if you `#include` both definitions. In case a
-Google Test macro clashes with another library, you can force Google Test to
-rename its macro to avoid the conflict.
-
-Specifically, if both Google Test and some other code define macro FOO, you can
-add
-
-    -DGTEST_DONT_DEFINE_FOO=1
-
-to the compiler flags to tell Google Test to change the macro's name from `FOO`
-to `GTEST_FOO`. Currently `FOO` can be `FAIL`, `SUCCEED`, or `TEST`. For
-example, with `-DGTEST_DONT_DEFINE_TEST=1`, you'll need to write
-
-    GTEST_TEST(SomeTest, DoesThis) { ... }
-
-instead of
-
-    TEST(SomeTest, DoesThis) { ... }
-
-in order to define a test.

-## Using GoogleTest from various build systems ##
-
-GoogleTest comes with pkg-config files that can be used to determine all
-necessary flags for compiling and linking to GoogleTest (and GoogleMock).
-Pkg-config is a standardised plain-text format containing
-
-  * the includedir (-I) path
-  * necessary macro (-D) definitions
-  * further required flags (-pthread)
-  * the library (-L) path
-  * the library (-l) to link to
-
-All current build systems support pkg-config in one way or another. For
-all examples here we assume you want to compile the sample
-`samples/sample3_unittest.cc`.
-
-
-### CMake ###
-
-Using `pkg-config` in CMake is fairly easy:
-
-```
-cmake_minimum_required(VERSION 3.0)
-
-cmake_policy(SET CMP0048 NEW)
-project(my_gtest_pkgconfig VERSION 0.0.1 LANGUAGES CXX)
-
-find_package(PkgConfig)
-pkg_search_module(GTEST REQUIRED gtest_main)
-
-add_executable(testapp samples/sample3_unittest.cc)
-target_link_libraries(testapp ${GTEST_LDFLAGS})
-target_compile_options(testapp PUBLIC ${GTEST_CFLAGS})
-
-include(CTest)
-add_test(first_and_only_test testapp)
-```
-
-It is generally recommended that you use `target_compile_options` + `_CFLAGS`
-over `target_include_directories` + `_INCLUDE_DIRS` as the former includes not
-just -I flags (GoogleTest might require a macro indicating to internal headers
-that all libraries have been compiled with threading enabled. In addition,
-GoogleTest might also require `-pthread` in the compiling step, and as such
-splitting the pkg-config `Cflags` variable into include dirs and macros for
-`target_compile_definitions()` might still miss this). The same recommendation
-goes for using `_LDFLAGS` over the more commonplace `_LIBRARIES`, which
-happens to discard `-L` flags and `-pthread`.
-
-
-### Autotools ###
-
-Finding GoogleTest in Autoconf and using it from Automake is also fairly easy:
-
-In your `configure.ac`:
-
-```
-AC_PREREQ([2.69])
-AC_INIT([my_gtest_pkgconfig], [0.0.1])
-AC_CONFIG_SRCDIR([samples/sample3_unittest.cc])
-AC_PROG_CXX
-
-PKG_CHECK_MODULES([GTEST], [gtest_main])
-
-AM_INIT_AUTOMAKE([foreign subdir-objects])
-AC_CONFIG_FILES([Makefile])
-AC_OUTPUT
-```
-
-and in your `Makefile.am`:
-
-```
-check_PROGRAMS = testapp
-TESTS = $(check_PROGRAMS)
-
-testapp_SOURCES = samples/sample3_unittest.cc
-testapp_CXXFLAGS = $(GTEST_CFLAGS)
-testapp_LDADD = $(GTEST_LIBS)
-```
-
-
-### Meson ###
-
-Meson natively uses pkgconfig to query dependencies:
-
-```
-project('my_gtest_pkgconfig', 'cpp', version : '0.0.1')
-
-gtest_dep = dependency('gtest_main')
-
-testapp = executable(
-  'testapp',
-  files(['samples/sample3_unittest.cc']),
-  dependencies : gtest_dep,
-  install : false)
-
-test('first_and_only_test', testapp)
-```
-
-
-### Plain Makefiles ###
-
-Since `pkg-config` is a small Unix command-line utility, it can be used
-in handwritten `Makefile`s too:
-
-```
-GTEST_CFLAGS = `pkg-config --cflags gtest_main`
-GTEST_LIBS = `pkg-config --libs gtest_main`
-
-.PHONY: tests all
-
-tests: all
-	./testapp
-
-all: testapp
-
-testapp: testapp.o
-	$(CXX) $(CXXFLAGS) $(LDFLAGS) $< -o $@ $(GTEST_LIBS)
-
-testapp.o: samples/sample3_unittest.cc
-	$(CXX) $(CPPFLAGS) $(CXXFLAGS) $< -c -o $@ $(GTEST_CFLAGS)
-```
-
-
-### Help! pkg-config can't find GoogleTest! ###
-
-Let's say you have a `CMakeLists.txt` along the lines of the one in this
-tutorial and you try to run `cmake`. It is very possible that you get a
-failure along the lines of:
-
-```
--- Checking for one of the modules 'gtest_main'
-CMake Error at /usr/share/cmake/Modules/FindPkgConfig.cmake:640 (message):
-  None of the required 'gtest_main' found
-```
-
-These failures are common if you installed GoogleTest yourself and have not
-sourced it from a distro or other package manager. If so, you need to tell
-pkg-config where it can find the `.pc` files containing the information.
-Say you installed GoogleTest to `/usr/local`, then it might be that the
-`.pc` files are installed under `/usr/local/lib64/pkgconfig`. If you set
-
-```
-export PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig
-```
-
-pkg-config will also try to look in `PKG_CONFIG_PATH` to find `gtest_main.pc`.

-
-# The Problem #
-
-Template and macro libraries often need to define many classes,
-functions, or macros that vary only (or almost only) in the number of
-arguments they take. It's a lot of repetitive, mechanical, and
-error-prone work.
-
-Variadic templates and variadic macros can alleviate the problem.
-However, while both are being considered by the C++ committee, neither
-is in the standard yet or widely supported by compilers.  Thus they
-are often not a good choice, especially when your code needs to be
-portable. And their capabilities are still limited.
-
-As a result, authors of such libraries often have to write scripts to
-generate their implementation. However, our experience is that it's
-tedious to write such scripts, which tend to reflect the structure of
-the generated code poorly and are often hard to read and edit. For
-example, a small change needed in the generated code may require some
-non-intuitive, non-trivial changes in the script. This is especially
-painful when experimenting with the code.
-
-# Our Solution #
-
-Pump (for Pump is Useful for Meta Programming, Pretty Useful for Meta
-Programming, or Practical Utility for Meta Programming, whichever you
-prefer) is a simple meta-programming tool for C++. The idea is that a
-programmer writes a `foo.pump` file which contains C++ code plus meta
-code that manipulates the C++ code. The meta code can handle
-iterations over a range, nested iterations, local meta variable
-definitions, simple arithmetic, and conditional expressions. You can
-view it as a small Domain-Specific Language. The meta language is
-designed to be non-intrusive (s.t. it won't confuse Emacs' C++ mode,
-for example) and concise, making Pump code intuitive and easy to
-maintain.
-
-## Highlights ##
-
-  * The implementation is in a single Python script and thus ultra portable: no build or installation is needed and it works cross platforms.
-  * Pump tries to be smart with respect to [Google's style guide](https://github.com/google/styleguide): it breaks long lines (easy to have when they are generated) at acceptable places to fit within 80 columns and indent the continuation lines correctly.
-  * The format is human-readable and more concise than XML.
-  * The format works relatively well with Emacs' C++ mode.
-
-## Examples ##
-
-The following Pump code (where meta keywords start with `$`, `[[` and `]]` are meta brackets, and `$$` starts a meta comment that ends with the line):
-
-```
-$var n = 3     $$ Defines a meta variable n.
-$range i 0..n  $$ Declares the range of meta iterator i (inclusive).
-$for i [[
-               $$ Meta loop.
-// Foo$i does blah for $i-ary predicates.
-$range j 1..i
-template <size_t N $for j [[, typename A$j]]>
-class Foo$i {
-$if i == 0 [[
-  blah a;
-]] $elif i <= 2 [[
-  blah b;
-]] $else [[
-  blah c;
-]]
-};
-
-]]
-```
-
-will be translated by the Pump compiler to:
-
-```
-// Foo0 does blah for 0-ary predicates.
-template <size_t N>
-class Foo0 {
-  blah a;
-};
-
-// Foo1 does blah for 1-ary predicates.
-template <size_t N, typename A1>
-class Foo1 {
-  blah b;
-};
-
-// Foo2 does blah for 2-ary predicates.
-template <size_t N, typename A1, typename A2>
-class Foo2 {
-  blah b;
-};
-
-// Foo3 does blah for 3-ary predicates.
-template <size_t N, typename A1, typename A2, typename A3>
-class Foo3 {
-  blah c;
-};
-```
-
-In another example,
-
-```
-$range i 1..n
-Func($for i + [[a$i]]);
-$$ The text between i and [[ is the separator between iterations.
-```
-
-will generate one of the following lines (without the comments), depending on the value of `n`:
-
-```
-Func();              // If n is 0.
-Func(a1);            // If n is 1.
-Func(a1 + a2);       // If n is 2.
-Func(a1 + a2 + a3);  // If n is 3.
-// And so on...
-```
-
-## Constructs ##
-
-We support the following meta programming constructs:
-
-| `$var id = exp` | Defines a named constant value. `$id` is valid util the end of the current meta lexical block. |
-|:----------------|:-----------------------------------------------------------------------------------------------|
-| `$range id exp..exp` | Sets the range of an iteration variable, which can be reused in multiple loops later.          |
-| `$for id sep [[ code ]]` | Iteration. The range of `id` must have been defined earlier. `$id` is valid in `code`.         |
-| `$($)`          | Generates a single `$` character.                                                              |
-| `$id`           | Value of the named constant or iteration variable.                                             |
-| `$(exp)`        | Value of the expression.                                                                       |
-| `$if exp [[ code ]] else_branch` | Conditional.                                                                                   |
-| `[[ code ]]`    | Meta lexical block.                                                                            |
-| `cpp_code`      | Raw C++ code.                                                                                  |
-| `$$ comment`    | Meta comment.                                                                                  |
-
-**Note:** To give the user some freedom in formatting the Pump source
-code, Pump ignores a new-line character if it's right after `$for foo`
-or next to `[[` or `]]`. Without this rule you'll often be forced to write
-very long lines to get the desired output. Therefore sometimes you may
-need to insert an extra new-line in such places for a new-line to show
-up in your output.
-
-## Grammar ##
-
-```
-code ::= atomic_code*
-atomic_code ::= $var id = exp
-    | $var id = [[ code ]]
-    | $range id exp..exp
-    | $for id sep [[ code ]]
-    | $($)
-    | $id
-    | $(exp)
-    | $if exp [[ code ]] else_branch
-    | [[ code ]]
-    | cpp_code
-sep ::= cpp_code | empty_string
-else_branch ::= $else [[ code ]]
-    | $elif exp [[ code ]] else_branch
-    | empty_string
-exp ::= simple_expression_in_Python_syntax
-```
-
-## Code ##
-
-You can find the source code of Pump in [scripts/pump.py](../scripts/pump.py). It is still
-very unpolished and lacks automated tests, although it has been
-successfully used many times. If you find a chance to use it in your
-project, please let us know what you think!  We also welcome help on
-improving Pump.
-
-## Real Examples ##
-
-You can find real-world applications of Pump in [Google Test](https://github.com/google/googletest/tree/master/googletest) and [Google Mock](https://github.com/google/googletest/tree/master/googlemock). The source file `foo.h.pump` generates `foo.h`.
-
-## Tips ##
-
-  * If a meta variable is followed by a letter or digit, you can separate them using `[[]]`, which inserts an empty string. For example `Foo$j[[]]Helper` generate `Foo1Helper` when `j` is 1.
-  * To avoid extra-long Pump source lines, you can break a line anywhere you want by inserting `[[]]` followed by a new line. Since any new-line character next to `[[` or `]]` is ignored, the generated code won't contain this new line.

-This guide will explain how to use the Google Testing Framework in your Xcode projects on Mac OS X. This tutorial begins by quickly explaining what to do for experienced users. After the quick start, the guide goes provides additional explanation about each step.
-
-# Quick Start #
-
-Here is the quick guide for using Google Test in your Xcode project.
-
-  1. Download the source from the [website](https://github.com/google/googletest) using this command: `svn checkout http://googletest.googlecode.com/svn/trunk/ googletest-read-only`.
-  1. Open up the `gtest.xcodeproj` in the `googletest-read-only/xcode/` directory and build the gtest.framework.
-  1. Create a new "Shell Tool" target in your Xcode project called something like "UnitTests".
-  1. Add the gtest.framework to your project and add it to the "Link Binary with Libraries" build phase of "UnitTests".
-  1. Add your unit test source code to the "Compile Sources" build phase of "UnitTests".
-  1. Edit the "UnitTests" executable and add an environment variable named "DYLD\_FRAMEWORK\_PATH" with a value equal to the path to the framework containing the gtest.framework relative to the compiled executable.
-  1. Build and Go.
-
-The following sections further explain each of the steps listed above in depth, describing in more detail how to complete it including some variations.
-
-# Get the Source #
-
-Currently, the gtest.framework discussed here isn't available in a tagged release of Google Test, it is only available in the trunk. As explained at the Google Test [site](https://github.com/google/googletest), you can get the code from anonymous SVN with this command:
-
-```
-svn checkout http://googletest.googlecode.com/svn/trunk/ googletest-read-only
-```
-
-Alternatively, if you are working with Subversion in your own code base, you can add Google Test as an external dependency to your own Subversion repository. By following this approach, everyone that checks out your svn repository will also receive a copy of Google Test (a specific version, if you wish) without having to check it out explicitly. This makes the set up of your project simpler and reduces the copied code in the repository.
-
-To use `svn:externals`, decide where you would like to have the external source reside. You might choose to put the external source inside the trunk, because you want it to be part of the branch when you make a release. However, keeping it outside the trunk in a version-tagged directory called something like `third-party/googletest/1.0.1`, is another option. Once the location is established, use `svn propedit svn:externals _directory_` to set the svn:externals property on a directory in your repository. This directory won't contain the code, but be its versioned parent directory.
-
-The command `svn propedit` will bring up your Subversion editor, making editing the long, (potentially multi-line) property simpler. This same method can be used to check out a tagged branch, by using the appropriate URL (e.g. `https://github.com/google/googletest/releases/tag/release-1.0.1`). Additionally, the svn:externals property allows the specification of a particular revision of the trunk with the `-r_##_` option (e.g. `externals/src/googletest -r60 http://googletest.googlecode.com/svn/trunk`).
-
-Here is an example of using the svn:externals properties on a trunk (read via `svn propget`) of a project. This value checks out a copy of Google Test into the `trunk/externals/src/googletest/` directory.
-
-```
-[Computer:svn] user$ svn propget svn:externals trunk
-externals/src/googletest http://googletest.googlecode.com/svn/trunk
-```
-
-# Add the Framework to Your Project #

-The next step is to build and add the gtest.framework to your own project. This guide describes two common ways below.
-
-  * **Option 1** --- The simplest way to add Google Test to your own project, is to open gtest.xcodeproj (found in the xcode/ directory of the Google Test trunk) and build the framework manually. Then, add the built framework into your project using the "Add->Existing Framework..." from the context menu or "Project->Add..." from the main menu. The gtest.framework is relocatable and contains the headers and object code that you'll need to make tests. This method requires rebuilding every time you upgrade Google Test in your project.
-  * **Option 2** --- If you are going to be living off the trunk of Google Test, incorporating its latest features into your unit tests (or are a Google Test developer yourself). You'll want to rebuild the framework every time the source updates. to do this, you'll need to add the gtest.xcodeproj file, not the framework itself, to your own Xcode project. Then, from the build products that are revealed by the project's disclosure triangle, you can find the gtest.framework, which can be added to your targets (discussed below).
-
-# Make a Test Target #
-
-To start writing tests, make a new "Shell Tool" target. This target template is available under BSD, Cocoa, or Carbon. Add your unit test source code to the "Compile Sources" build phase of the target.
-
-Next, you'll want to add gtest.framework in two different ways, depending upon which option you chose above.
-
-  * **Option 1** --- During compilation, Xcode will need to know that you are linking against the gtest.framework. Add the gtest.framework to the "Link Binary with Libraries" build phase of your test target. This will include the Google Test headers in your header search path, and will tell the linker where to find the library.
-  * **Option 2** --- If your working out of the trunk, you'll also want to add gtest.framework to your "Link Binary with Libraries" build phase of your test target. In addition, you'll  want to add the gtest.framework as a dependency to your unit test target. This way, Xcode will make sure that gtest.framework is up to date, every time your build your target. Finally, if you don't share build directories with Google Test, you'll have to copy the gtest.framework into your own build products directory using a "Run Script" build phase.
-
-# Set Up the Executable Run Environment #
-
-Since the unit test executable is a shell tool, it doesn't have a bundle with a `Contents/Frameworks` directory, in which to place gtest.framework. Instead, the dynamic linker must be told at runtime to search for the framework in another location. This can be accomplished by setting the "DYLD\_FRAMEWORK\_PATH" environment variable in the "Edit Active Executable ..." Arguments tab, under "Variables to be set in the environment:". The path for this value is the path (relative or absolute) of the directory containing the gtest.framework.
-
-If you haven't set up the DYLD\_FRAMEWORK\_PATH, correctly, you might get a message like this:
-
-```
-[Session started at 2008-08-15 06:23:57 -0600.]
-  dyld: Library not loaded: @loader_path/../Frameworks/gtest.framework/Versions/A/gtest
-    Referenced from: /Users/username/Documents/Sandbox/gtestSample/build/Debug/WidgetFrameworkTest
-    Reason: image not found
-```
-
-To correct this problem, go to to the directory containing the executable named in "Referenced from:" value in the error message above. Then, with the terminal in this location, find the relative path to the directory containing the gtest.framework. That is the value you'll need to set as the DYLD\_FRAMEWORK\_PATH.
-
-# Build and Go #
-
-Now, when you click "Build and Go", the test will be executed. Dumping out something like this:
-
-```
-[Session started at 2008-08-06 06:36:13 -0600.]
-[==========] Running 2 tests from 1 test case.

-[==========] 2 tests from 1 test case ran.
-[  PASSED  ] 2 tests.

-```
-
-# Summary #
-
-Unit testing is a valuable way to ensure your data model stays valid even during rapid development or refactoring. The Google Testing Framework is a great unit testing framework for C and C++ which integrates well with an Xcode development environment.

-# Advanced googletest Topics
-
-
-## Introduction
-
-Now that you have read the [googletest Primer](primer.md) and learned how to write
-tests using googletest, it's time to learn some new tricks. This document will
-show you more assertions as well as how to construct complex failure messages,
-propagate fatal failures, reuse and speed up your test fixtures, and use various
-flags with your tests.
-
-## More Assertions
-
-This section covers some less frequently used, but still significant,
-assertions.
-
-### Explicit Success and Failure
-
-These three assertions do not actually test a value or expression. Instead, they
-generate a success or failure directly. Like the macros that actually perform a
-test, you may stream a custom failure message into them.
-
-```c++
-SUCCEED();
-```
-
-Generates a success. This does **NOT** make the overall test succeed. A test is
-considered successful only if none of its assertions fail during its execution.
-
-NOTE: `SUCCEED()` is purely documentary and currently doesn't generate any
-user-visible output. However, we may add `SUCCEED()` messages to googletest's
-output in the future.
-
-```c++
-FAIL();
-ADD_FAILURE();
-ADD_FAILURE_AT("file_path", line_number);
-```
-
-`FAIL()` generates a fatal failure, while `ADD_FAILURE()` and `ADD_FAILURE_AT()`
-generate a nonfatal failure. These are useful when control flow, rather than a
-Boolean expression, determines the test's success or failure. For example, you
-might want to write something like:
-
-```c++
-switch(expression) {
-  case 1:
-     ... some checks ...
-  case 2:
-     ... some other checks ...
-  default:
-     FAIL() << "We shouldn't get here.";
-}
-```
-
-NOTE: you can only use `FAIL()` in functions that return `void`. See the
-[Assertion Placement section](#assertion-placement) for more information.
-
-**Availability**: Linux, Windows, Mac.
-
-### Exception Assertions
-
-These are for verifying that a piece of code throws (or does not throw) an
-exception of the given type:
-
-Fatal assertion                            | Nonfatal assertion                         | Verifies
------------------------------------------- | ------------------------------------------ | --------
-`ASSERT_THROW(statement, exception_type);` | `EXPECT_THROW(statement, exception_type);` | `statement` throws an exception of the given type
-`ASSERT_ANY_THROW(statement);`             | `EXPECT_ANY_THROW(statement);`             | `statement` throws an exception of any type
-`ASSERT_NO_THROW(statement);`              | `EXPECT_NO_THROW(statement);`              | `statement` doesn't throw any exception
-
-Examples:
-
-```c++
-ASSERT_THROW(Foo(5), bar_exception);
-
-EXPECT_NO_THROW({
-  int n = 5;
-  Bar(&n);
-});
-```
-
-**Availability**: Linux, Windows, Mac; requires exceptions to be enabled in the
-build environment (note that `google3` **disables** exceptions).
-
-### Predicate Assertions for Better Error Messages
-
-Even though googletest has a rich set of assertions, they can never be complete,
-as it's impossible (nor a good idea) to anticipate all scenarios a user might
-run into. Therefore, sometimes a user has to use `EXPECT_TRUE()` to check a
-complex expression, for lack of a better macro. This has the problem of not
-showing you the values of the parts of the expression, making it hard to
-understand what went wrong. As a workaround, some users choose to construct the
-failure message by themselves, streaming it into `EXPECT_TRUE()`. However, this
-is awkward especially when the expression has side-effects or is expensive to
-evaluate.
-
-googletest gives you three different options to solve this problem:
-
-#### Using an Existing Boolean Function
-
-If you already have a function or functor that returns `bool` (or a type that
-can be implicitly converted to `bool`), you can use it in a *predicate
-assertion* to get the function arguments printed for free:
-
-| Fatal assertion                    | Nonfatal assertion                 | Verifies                    |
-| ---------------------------------- | ---------------------------------- | --------------------------- |
-| `ASSERT_PRED1(pred1, val1);`       | `EXPECT_PRED1(pred1, val1);`       | `pred1(val1)` is true       |
-| `ASSERT_PRED2(pred2, val1, val2);` | `EXPECT_PRED2(pred2, val1, val2);` | `pred2(val1, val2)` is true |
-| `...`                              | `...`                              | ...                         |
-
-In the above, `predn` is an `n`-ary predicate function or functor, where `val1`,
-`val2`, ..., and `valn` are its arguments. The assertion succeeds if the
-predicate returns `true` when applied to the given arguments, and fails
-otherwise. When the assertion fails, it prints the value of each argument. In
-either case, the arguments are evaluated exactly once.
-
-Here's an example. Given
-
-```c++
-// Returns true if m and n have no common divisors except 1.
-bool MutuallyPrime(int m, int n) { ... }
-
-const int a = 3;
-const int b = 4;
-const int c = 10;
-```
-
-the assertion
-
-```c++
-  EXPECT_PRED2(MutuallyPrime, a, b);
-```
-
-will succeed, while the assertion
-
-```c++
-  EXPECT_PRED2(MutuallyPrime, b, c);
-```
-
-will fail with the message
-
-```none
-MutuallyPrime(b, c) is false, where
-b is 4
-c is 10
-```
-
-> NOTE:
->
-> 1.  If you see a compiler error "no matching function to call" when using
->     `ASSERT_PRED*` or `EXPECT_PRED*`, please see
->     [this](faq.md#OverloadedPredicate) for how to resolve it.
-> 1.  Currently we only provide predicate assertions of arity <= 5. If you need
->     a higher-arity assertion, let [us](https://github.com/google/googletest/issues) know.
-
-**Availability**: Linux, Windows, Mac.
-
-#### Using a Function That Returns an AssertionResult
-
-While `EXPECT_PRED*()` and friends are handy for a quick job, the syntax is not
-satisfactory: you have to use different macros for different arities, and it
-feels more like Lisp than C++. The `::testing::AssertionResult` class solves
-this problem.
-
-An `AssertionResult` object represents the result of an assertion (whether it's
-a success or a failure, and an associated message). You can create an
-`AssertionResult` using one of these factory functions:
-
-```c++
-namespace testing {
-
-// Returns an AssertionResult object to indicate that an assertion has
-// succeeded.
-AssertionResult AssertionSuccess();
-
-// Returns an AssertionResult object to indicate that an assertion has
-// failed.
-AssertionResult AssertionFailure();
-
-}
-```
-
-You can then use the `<<` operator to stream messages to the `AssertionResult`
-object.
-
-To provide more readable messages in Boolean assertions (e.g. `EXPECT_TRUE()`),
-write a predicate function that returns `AssertionResult` instead of `bool`. For
-example, if you define `IsEven()` as:
-
-```c++
-::testing::AssertionResult IsEven(int n) {
-  if ((n % 2) == 0)
-     return ::testing::AssertionSuccess();
-  else
-     return ::testing::AssertionFailure() << n << " is odd";
-}
-```
-
-instead of:
-
-```c++
-bool IsEven(int n) {
-  return (n % 2) == 0;
-}
-```
-
-the failed assertion `EXPECT_TRUE(IsEven(Fib(4)))` will print:
-
-```none
-Value of: IsEven(Fib(4))
-  Actual: false (3 is odd)
-Expected: true
-```
-
-instead of a more opaque
-
-```none
-Value of: IsEven(Fib(4))
-  Actual: false
-Expected: true
-```
-
-If you want informative messages in `EXPECT_FALSE` and `ASSERT_FALSE` as well
-(one third of Boolean assertions in the Google code base are negative ones), and
-are fine with making the predicate slower in the success case, you can supply a
-success message:
-
-```c++
-::testing::AssertionResult IsEven(int n) {
-  if ((n % 2) == 0)
-     return ::testing::AssertionSuccess() << n << " is even";
-  else
-     return ::testing::AssertionFailure() << n << " is odd";
-}
-```
-
-Then the statement `EXPECT_FALSE(IsEven(Fib(6)))` will print
-
-```none
-  Value of: IsEven(Fib(6))
-     Actual: true (8 is even)
-  Expected: false
-```
-
-**Availability**: Linux, Windows, Mac.
-
-#### Using a Predicate-Formatter
-
-If you find the default message generated by `(ASSERT|EXPECT)_PRED*` and
-`(ASSERT|EXPECT)_(TRUE|FALSE)` unsatisfactory, or some arguments to your
-predicate do not support streaming to `ostream`, you can instead use the
-following *predicate-formatter assertions* to *fully* customize how the message
-is formatted:
-
-Fatal assertion                                  | Nonfatal assertion                               | Verifies
------------------------------------------------- | ------------------------------------------------ | --------
-`ASSERT_PRED_FORMAT1(pred_format1, val1);`       | `EXPECT_PRED_FORMAT1(pred_format1, val1);`       | `pred_format1(val1)` is successful
-`ASSERT_PRED_FORMAT2(pred_format2, val1, val2);` | `EXPECT_PRED_FORMAT2(pred_format2, val1, val2);` | `pred_format2(val1, val2)` is successful
-`...`                                            | `...`                                            | ...
-
-The difference between this and the previous group of macros is that instead of
-a predicate, `(ASSERT|EXPECT)_PRED_FORMAT*` take a *predicate-formatter*
-(`pred_formatn`), which is a function or functor with the signature:
-
-```c++
-::testing::AssertionResult PredicateFormattern(const char* expr1,
-                                               const char* expr2,
-                                               ...
-                                               const char* exprn,
-                                               T1 val1,
-                                               T2 val2,
-                                               ...
-                                               Tn valn);
-```
-
-where `val1`, `val2`, ..., and `valn` are the values of the predicate arguments,
-and `expr1`, `expr2`, ..., and `exprn` are the corresponding expressions as they
-appear in the source code. The types `T1`, `T2`, ..., and `Tn` can be either
-value types or reference types. For example, if an argument has type `Foo`, you
-can declare it as either `Foo` or `const Foo&`, whichever is appropriate.
-
-As an example, let's improve the failure message in `MutuallyPrime()`, which was
-used with `EXPECT_PRED2()`:
-
-```c++
-// Returns the smallest prime common divisor of m and n,
-// or 1 when m and n are mutually prime.
-int SmallestPrimeCommonDivisor(int m, int n) { ... }
-
-// A predicate-formatter for asserting that two integers are mutually prime.
-::testing::AssertionResult AssertMutuallyPrime(const char* m_expr,
-                                               const char* n_expr,
-                                               int m,
-                                               int n) {
-  if (MutuallyPrime(m, n)) return ::testing::AssertionSuccess();
-
-  return ::testing::AssertionFailure() << m_expr << " and " << n_expr
-      << " (" << m << " and " << n << ") are not mutually prime, "
-      << "as they have a common divisor " << SmallestPrimeCommonDivisor(m, n);
-}
-```
-
-With this predicate-formatter, we can use
-
-```c++
-  EXPECT_PRED_FORMAT2(AssertMutuallyPrime, b, c);
-```
-
-to generate the message
-
-```none
-b and c (4 and 10) are not mutually prime, as they have a common divisor 2.
-```
-
-As you may have realized, many of the built-in assertions we introduced earlier
-are special cases of `(EXPECT|ASSERT)_PRED_FORMAT*`. In fact, most of them are
-indeed defined using `(EXPECT|ASSERT)_PRED_FORMAT*`.

-### Floating-Point Comparison
-
-Comparing floating-point numbers is tricky. Due to round-off errors, it is very
-unlikely that two floating-points will match exactly. Therefore, `ASSERT_EQ` 's
-naive comparison usually doesn't work. And since floating-points can have a wide
-value range, no single fixed error bound works. It's better to compare by a
-fixed relative error bound, except for values close to 0 due to the loss of
-precision there.
-
-In general, for floating-point comparison to make sense, the user needs to
-carefully choose the error bound. If they don't want or care to, comparing in
-terms of Units in the Last Place (ULPs) is a good default, and googletest
-provides assertions to do this. Full details about ULPs are quite long; if you
-want to learn more, see
-[here](https://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/).
-
-#### Floating-Point Macros
-
-| Fatal assertion                 | Nonfatal assertion             | Verifies                                 |
-| ------------------------------- | ------------------------------ | ---------------------------------------- |
-| `ASSERT_FLOAT_EQ(val1, val2);`  | `EXPECT_FLOAT_EQ(val1,val2);`  | the two `float` values are almost equal  |
-| `ASSERT_DOUBLE_EQ(val1, val2);` | `EXPECT_DOUBLE_EQ(val1, val2);`| the two `double` values are almost equal |
-
-By "almost equal" we mean the values are within 4 ULP's from each other.
-
-NOTE: `CHECK_DOUBLE_EQ()` in `base/logging.h` uses a fixed absolute error bound,
-so its result may differ from that of the googletest macros. That macro is
-unsafe and has been deprecated. Please don't use it any more.
-
-The following assertions allow you to choose the acceptable error bound:
-
-| Fatal assertion                       | Nonfatal assertion                    | Verifies                  |
-| ------------------------------------- | ------------------------------------- | ------------------------- |
-| `ASSERT_NEAR(val1, val2, abs_error);` | `EXPECT_NEAR(val1, val2, abs_error);` | the difference between `val1` and `val2` doesn't exceed the given absolute error |
-
-**Availability**: Linux, Windows, Mac.
-
-#### Floating-Point Predicate-Format Functions
-
-Some floating-point operations are useful, but not that often used. In order to
-avoid an explosion of new macros, we provide them as predicate-format functions
-that can be used in predicate assertion macros (e.g. `EXPECT_PRED_FORMAT2`,
-etc).
-
-```c++
-EXPECT_PRED_FORMAT2(::testing::FloatLE, val1, val2);
-EXPECT_PRED_FORMAT2(::testing::DoubleLE, val1, val2);
-```
-
-Verifies that `val1` is less than, or almost equal to, `val2`. You can replace
-`EXPECT_PRED_FORMAT2` in the above table with `ASSERT_PRED_FORMAT2`.
-
-**Availability**: Linux, Windows, Mac.
-
-### Asserting Using gMock Matchers
-
-Google-developed C++ mocking framework [gMock](../../googlemock) comes with a
-library of matchers for validating arguments passed to mock objects. A gMock
-*matcher* is basically a predicate that knows how to describe itself. It can be
-used in these assertion macros:
-
-| Fatal assertion                | Nonfatal assertion             | Verifies              |
-| ------------------------------ | ------------------------------ | --------------------- |
-| `ASSERT_THAT(value, matcher);` | `EXPECT_THAT(value, matcher);` | value matches matcher |
-
-For example, `StartsWith(prefix)` is a matcher that matches a string starting
-with `prefix`, and you can write:
-
-```c++
-using ::testing::StartsWith;
-...
-    // Verifies that Foo() returns a string starting with "Hello".
-    EXPECT_THAT(Foo(), StartsWith("Hello"));
-```
-
-Read this [recipe](../../googlemock/docs/CookBook.md#using-matchers-in-google-test-assertions) in
-the gMock Cookbook for more details.
-
-gMock has a rich set of matchers. You can do many things googletest cannot do
-alone with them. For a list of matchers gMock provides, read
-[this](../../googlemock/docs/CookBook.md#using-matchers). Especially useful among them are
-some [protocol buffer matchers](https://github.com/google/nucleus/blob/master/nucleus/testing/protocol-buffer-matchers.h). It's easy to write
-your [own matchers](../../googlemock/docs/CookBook.md#writing-new-matchers-quickly) too.
-
-For example, you can use gMock's
-[EqualsProto](https://github.com/google/nucleus/blob/master/nucleus/testing/protocol-buffer-matchers.h)
-to compare protos in your tests:
-
-```c++
-#include "testing/base/public/gmock.h"
-using ::testing::EqualsProto;
-...
-    EXPECT_THAT(actual_proto, EqualsProto("foo: 123 bar: 'xyz'"));
-    EXPECT_THAT(*actual_proto_ptr, EqualsProto(expected_proto));
-```
-
-gMock is bundled with googletest, so you don't need to add any build dependency
-in order to take advantage of this. Just include `"testing/base/public/gmock.h"`
-and you're ready to go.
-
-**Availability**: Linux, Windows, and Mac.
-
-### More String Assertions
-
-(Please read the [previous](#AssertThat) section first if you haven't.)
-
-You can use the gMock [string matchers](../../googlemock/docs/CheatSheet.md#string-matchers)
-with `EXPECT_THAT()` or `ASSERT_THAT()` to do more string comparison tricks
-(sub-string, prefix, suffix, regular expression, and etc). For example,
-
-```c++
-using ::testing::HasSubstr;
-using ::testing::MatchesRegex;
-...
-  ASSERT_THAT(foo_string, HasSubstr("needle"));
-  EXPECT_THAT(bar_string, MatchesRegex("\\w*\\d+"));
-```
-
-**Availability**: Linux, Windows, Mac.
-
-If the string contains a well-formed HTML or XML document, you can check whether
-its DOM tree matches an [XPath
-expression](http://www.w3.org/TR/xpath/#contents):
-
-```c++
-// Currently still in //template/prototemplate/testing:xpath_matcher
-#include "template/prototemplate/testing/xpath_matcher.h"
-using prototemplate::testing::MatchesXPath;
-EXPECT_THAT(html_string, MatchesXPath("//a[text()='click here']"));
-```
-
-**Availability**: Linux.
-
-### Windows HRESULT assertions
-
-These assertions test for `HRESULT` success or failure.
-
-Fatal assertion                        | Nonfatal assertion                     | Verifies
--------------------------------------- | -------------------------------------- | --------
-`ASSERT_HRESULT_SUCCEEDED(expression)` | `EXPECT_HRESULT_SUCCEEDED(expression)` | `expression` is a success `HRESULT`
-`ASSERT_HRESULT_FAILED(expression)`    | `EXPECT_HRESULT_FAILED(expression)`    | `expression` is a failure `HRESULT`
-
-The generated output contains the human-readable error message associated with
-the `HRESULT` code returned by `expression`.
-
-You might use them like this:
-
-```c++
-CComPtr<IShellDispatch2> shell;
-ASSERT_HRESULT_SUCCEEDED(shell.CoCreateInstance(L"Shell.Application"));
-CComVariant empty;
-ASSERT_HRESULT_SUCCEEDED(shell->ShellExecute(CComBSTR(url), empty, empty, empty, empty));
-```
-
-**Availability**: Windows.
-
-### Type Assertions
-
-You can call the function
-
-```c++
-::testing::StaticAssertTypeEq<T1, T2>();
-```
-
-to assert that types `T1` and `T2` are the same. The function does nothing if
-the assertion is satisfied. If the types are different, the function call will
-fail to compile, and the compiler error message will likely (depending on the
-compiler) show you the actual values of `T1` and `T2`. This is mainly useful
-inside template code.
-
-**Caveat**: When used inside a member function of a class template or a function
-template, `StaticAssertTypeEq<T1, T2>()` is effective only if the function is
-instantiated. For example, given:
-
-```c++
-template <typename T> class Foo {
- public:
-  void Bar() { ::testing::StaticAssertTypeEq<int, T>(); }
-};
-```
-
-the code:
-
-```c++
-void Test1() { Foo<bool> foo; }
-```
-
-will not generate a compiler error, as `Foo<bool>::Bar()` is never actually
-instantiated. Instead, you need:
-
-```c++
-void Test2() { Foo<bool> foo; foo.Bar(); }
-```
-
-to cause a compiler error.

-
-### Assertion Placement
-
-You can use assertions in any C++ function. In particular, it doesn't have to be
-a method of the test fixture class. The one constraint is that assertions that
-generate a fatal failure (`FAIL*` and `ASSERT_*`) can only be used in
-void-returning functions. This is a consequence of Google's not using
-exceptions. By placing it in a non-void function you'll get a confusing compile
-error like `"error: void value not ignored as it ought to be"` or `"cannot
-initialize return object of type 'bool' with an rvalue of type 'void'"` or
-`"error: no viable conversion from 'void' to 'string'"`.
-
-If you need to use fatal assertions in a function that returns non-void, one
-option is to make the function return the value in an out parameter instead. For
-example, you can rewrite `T2 Foo(T1 x)` to `void Foo(T1 x, T2* result)`. You
-need to make sure that `*result` contains some sensible value even when the
-function returns prematurely. As the function now returns `void`, you can use
-any assertion inside of it.
-
-If changing the function's type is not an option, you should just use assertions
-that generate non-fatal failures, such as `ADD_FAILURE*` and `EXPECT_*`.
-
-NOTE: Constructors and destructors are not considered void-returning functions,
-according to the C++ language specification, and so you may not use fatal
-assertions in them. You'll get a compilation error if you try. A simple
-workaround is to transfer the entire body of the constructor or destructor to a
-private void-returning method. However, you should be aware that a fatal
-assertion failure in a constructor does not terminate the current test, as your
-intuition might suggest; it merely returns from the constructor early, possibly
-leaving your object in a partially-constructed state. Likewise, a fatal
-assertion failure in a destructor may leave your object in a
-partially-destructed state. Use assertions carefully in these situations!
-
-## Teaching googletest How to Print Your Values
-
-When a test assertion such as `EXPECT_EQ` fails, googletest prints the argument
-values to help you debug. It does this using a user-extensible value printer.
-
-This printer knows how to print built-in C++ types, native arrays, STL
-containers, and any type that supports the `<<` operator. For other types, it
-prints the raw bytes in the value and hopes that you the user can figure it out.
-
-As mentioned earlier, the printer is *extensible*. That means you can teach it
-to do a better job at printing your particular type than to dump the bytes. To
-do that, define `<<` for your type:
-
-```c++
-// Streams are allowed only for logging.  Don't include this for
-// any other purpose.
-#include <ostream>
-
-namespace foo {
-
-class Bar {  // We want googletest to be able to print instances of this.
-...
-  // Create a free inline friend function.
-  friend std::ostream& operator<<(std::ostream& os, const Bar& bar) {
-    return os << bar.DebugString();  // whatever needed to print bar to os
-  }
-};
-
-// If you can't declare the function in the class it's important that the
-// << operator is defined in the SAME namespace that defines Bar.  C++'s look-up
-// rules rely on that.
-std::ostream& operator<<(std::ostream& os, const Bar& bar) {
-  return os << bar.DebugString();  // whatever needed to print bar to os
-}
-
-}  // namespace foo
-```
-
-Sometimes, this might not be an option: your team may consider it bad style to
-have a `<<` operator for `Bar`, or `Bar` may already have a `<<` operator that
-doesn't do what you want (and you cannot change it). If so, you can instead
-define a `PrintTo()` function like this:
-
-```c++
-// Streams are allowed only for logging.  Don't include this for
-// any other purpose.
-#include <ostream>
-
-namespace foo {
-
-class Bar {
-  ...
-  friend void PrintTo(const Bar& bar, std::ostream* os) {
-    *os << bar.DebugString();  // whatever needed to print bar to os
-  }
-};
-
-// If you can't declare the function in the class it's important that PrintTo()
-// is defined in the SAME namespace that defines Bar.  C++'s look-up rules rely
-// on that.
-void PrintTo(const Bar& bar, std::ostream* os) {
-  *os << bar.DebugString();  // whatever needed to print bar to os
-}
-
-}  // namespace foo
-```
-
-If you have defined both `<<` and `PrintTo()`, the latter will be used when
-googletest is concerned. This allows you to customize how the value appears in
-googletest's output without affecting code that relies on the behavior of its
-`<<` operator.
-
-If you want to print a value `x` using googletest's value printer yourself, just
-call `::testing::PrintToString(x)`, which returns an `std::string`:
-
-```c++
-vector<pair<Bar, int> > bar_ints = GetBarIntVector();
-
-EXPECT_TRUE(IsCorrectBarIntVector(bar_ints))
-    << "bar_ints = " << ::testing::PrintToString(bar_ints);
-```
-
-## Death Tests
-
-In many applications, there are assertions that can cause application failure if
-a condition is not met. These sanity checks, which ensure that the program is in
-a known good state, are there to fail at the earliest possible time after some
-program state is corrupted. If the assertion checks the wrong condition, then
-the program may proceed in an erroneous state, which could lead to memory
-corruption, security holes, or worse. Hence it is vitally important to test that
-such assertion statements work as expected.
-
-Since these precondition checks cause the processes to die, we call such tests
-_death tests_. More generally, any test that checks that a program terminates
-(except by throwing an exception) in an expected fashion is also a death test.
-
-
-Note that if a piece of code throws an exception, we don't consider it "death"
-for the purpose of death tests, as the caller of the code could catch the
-exception and avoid the crash. If you want to verify exceptions thrown by your
-code, see [Exception Assertions](#exception-assertions).
-
-If you want to test `EXPECT_*()/ASSERT_*()` failures in your test code, see
-Catching Failures
-
-### How to Write a Death Test
-
-googletest has the following macros to support death tests:
-
-Fatal assertion                                | Nonfatal assertion                             | Verifies
----------------------------------------------- | ---------------------------------------------- | --------
-`ASSERT_DEATH(statement, regex);`              | `EXPECT_DEATH(statement, regex);`              | `statement` crashes with the given error
-`ASSERT_DEATH_IF_SUPPORTED(statement, regex);` | `EXPECT_DEATH_IF_SUPPORTED(statement, regex);` | if death tests are supported, verifies that `statement` crashes with the given error; otherwise verifies nothing
-`ASSERT_EXIT(statement, predicate, regex);`    | `EXPECT_EXIT(statement, predicate, regex);`    | `statement` exits with the given error, and its exit code matches `predicate`
-
-where `statement` is a statement that is expected to cause the process to die,
-`predicate` is a function or function object that evaluates an integer exit
-status, and `regex` is a (Perl) regular expression that the stderr output of
-`statement` is expected to match. Note that `statement` can be *any valid
-statement* (including *compound statement*) and doesn't have to be an
-expression.
-
-
-As usual, the `ASSERT` variants abort the current test function, while the
-`EXPECT` variants do not.
-
-> NOTE: We use the word "crash" here to mean that the process terminates with a
-> *non-zero* exit status code. There are two possibilities: either the process
-> has called `exit()` or `_exit()` with a non-zero value, or it may be killed by
-> a signal.
->
-> This means that if `*statement*` terminates the process with a 0 exit code, it
-> is *not* considered a crash by `EXPECT_DEATH`. Use `EXPECT_EXIT` instead if
-> this is the case, or if you want to restrict the exit code more precisely.
-
-A predicate here must accept an `int` and return a `bool`. The death test
-succeeds only if the predicate returns `true`. googletest defines a few
-predicates that handle the most common cases:
-
-```c++
-::testing::ExitedWithCode(exit_code)
-```
-
-This expression is `true` if the program exited normally with the given exit
-code.
-
-```c++
-::testing::KilledBySignal(signal_number)  // Not available on Windows.
-```
-
-This expression is `true` if the program was killed by the given signal.
-
-The `*_DEATH` macros are convenient wrappers for `*_EXIT` that use a predicate
-that verifies the process' exit code is non-zero.
-
-Note that a death test only cares about three things:
-
-1.  does `statement` abort or exit the process?
-2.  (in the case of `ASSERT_EXIT` and `EXPECT_EXIT`) does the exit status
-    satisfy `predicate`? Or (in the case of `ASSERT_DEATH` and `EXPECT_DEATH`)
-    is the exit status non-zero? And
-3.  does the stderr output match `regex`?
-
-In particular, if `statement` generates an `ASSERT_*` or `EXPECT_*` failure, it
-will **not** cause the death test to fail, as googletest assertions don't abort
-the process.
-
-To write a death test, simply use one of the above macros inside your test
-function. For example,
-
-```c++
-TEST(MyDeathTest, Foo) {
-  // This death test uses a compound statement.
-  ASSERT_DEATH({
-    int n = 5;
-    Foo(&n);
-  }, "Error on line .* of Foo()");
-}
-
-TEST(MyDeathTest, NormalExit) {
-  EXPECT_EXIT(NormalExit(), ::testing::ExitedWithCode(0), "Success");
-}
-
-TEST(MyDeathTest, KillMyself) {
-  EXPECT_EXIT(KillMyself(), ::testing::KilledBySignal(SIGKILL),
-              "Sending myself unblockable signal");
-}
-```
-
-verifies that:
-
-*   calling `Foo(5)` causes the process to die with the given error message,
-*   calling `NormalExit()` causes the process to print `"Success"` to stderr and
-    exit with exit code 0, and
-*   calling `KillMyself()` kills the process with signal `SIGKILL`.
-
-The test function body may contain other assertions and statements as well, if
-necessary.
-
-### Death Test Naming
-
-IMPORTANT: We strongly recommend you to follow the convention of naming your
-**test case** (not test) `*DeathTest` when it contains a death test, as
-demonstrated in the above example. The [Death Tests And
-Threads](#death-tests-and-threads) section below explains why.
-
-If a test fixture class is shared by normal tests and death tests, you can use
-`using` or `typedef` to introduce an alias for the fixture class and avoid
-duplicating its code:
-
-```c++
-class FooTest : public ::testing::Test { ... };
-
-using FooDeathTest = FooTest;
-
-TEST_F(FooTest, DoesThis) {
-  // normal test
-}
-
-TEST_F(FooDeathTest, DoesThat) {
-  // death test
-}
-```
-
-**Availability**: Linux, Windows (requires MSVC 8.0 or above), Cygwin, and Mac
-
-### Regular Expression Syntax
-
-
-On POSIX systems (e.g. Linux, Cygwin, and Mac), googletest uses the
-[POSIX extended regular expression](http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap09.html#tag_09_04)
-syntax. To learn about this syntax, you may want to read this
-[Wikipedia entry](http://en.wikipedia.org/wiki/Regular_expression#POSIX_Extended_Regular_Expressions).
-
-On Windows, googletest uses its own simple regular expression implementation. It
-lacks many features. For example, we don't support union (`"x|y"`), grouping
-(`"(xy)"`), brackets (`"[xy]"`), and repetition count (`"x{5,7}"`), among
-others. Below is what we do support (`A` denotes a literal character, period
-(`.`), or a single `\\ ` escape sequence; `x` and `y` denote regular
-expressions.):
-
-Expression | Meaning
----------- | --------------------------------------------------------------
-`c`        | matches any literal character `c`
-`\\d`      | matches any decimal digit
-`\\D`      | matches any character that's not a decimal digit
-`\\f`      | matches `\f`
-`\\n`      | matches `\n`
-`\\r`      | matches `\r`
-`\\s`      | matches any ASCII whitespace, including `\n`
-`\\S`      | matches any character that's not a whitespace
-`\\t`      | matches `\t`
-`\\v`      | matches `\v`
-`\\w`      | matches any letter, `_`, or decimal digit
-`\\W`      | matches any character that `\\w` doesn't match
-`\\c`      | matches any literal character `c`, which must be a punctuation
-`.`        | matches any single character except `\n`
-`A?`       | matches 0 or 1 occurrences of `A`
-`A*`       | matches 0 or many occurrences of `A`
-`A+`       | matches 1 or many occurrences of `A`
-`^`        | matches the beginning of a string (not that of each line)
-`$`        | matches the end of a string (not that of each line)
-`xy`       | matches `x` followed by `y`
-
-To help you determine which capability is available on your system, googletest
-defines macros to govern which regular expression it is using. The macros are:
-<!--absl:google3-begin(google3-only)-->`GTEST_USES_PCRE=1`, or
-<!--absl:google3-end--> `GTEST_USES_SIMPLE_RE=1` or `GTEST_USES_POSIX_RE=1`. If
-you want your death tests to work in all cases, you can either `#if` on these
-macros or use the more limited syntax only.
-
-### How It Works
-
-Under the hood, `ASSERT_EXIT()` spawns a new process and executes the death test
-statement in that process. The details of how precisely that happens depend on
-the platform and the variable ::testing::GTEST_FLAG(death_test_style) (which is
-initialized from the command-line flag `--gtest_death_test_style`).
-
-*   On POSIX systems, `fork()` (or `clone()` on Linux) is used to spawn the
-    child, after which:
-    *   If the variable's value is `"fast"`, the death test statement is
-        immediately executed.
-    *   If the variable's value is `"threadsafe"`, the child process re-executes
-        the unit test binary just as it was originally invoked, but with some
-        extra flags to cause just the single death test under consideration to
-        be run.
-*   On Windows, the child is spawned using the `CreateProcess()` API, and
-    re-executes the binary to cause just the single death test under
-    consideration to be run - much like the `threadsafe` mode on POSIX.
-
-Other values for the variable are illegal and will cause the death test to fail.
-Currently, the flag's default value is
-"fast". However, we reserve
-the right to change it in the future. Therefore, your tests should not depend on
-this. In either case, the parent process waits for the child process to
-complete, and checks that
-
-1.  the child's exit status satisfies the predicate, and
-2.  the child's stderr matches the regular expression.
-
-If the death test statement runs to completion without dying, the child process
-will nonetheless terminate, and the assertion fails.
-
-### Death Tests And Threads
-
-The reason for the two death test styles has to do with thread safety. Due to
-well-known problems with forking in the presence of threads, death tests should
-be run in a single-threaded context. Sometimes, however, it isn't feasible to
-arrange that kind of environment. For example, statically-initialized modules
-may start threads before main is ever reached. Once threads have been created,
-it may be difficult or impossible to clean them up.
-
-googletest has three features intended to raise awareness of threading issues.
-
-1.  A warning is emitted if multiple threads are running when a death test is
-    encountered.
-2.  Test cases with a name ending in "DeathTest" are run before all other tests.
-3.  It uses `clone()` instead of `fork()` to spawn the child process on Linux
-    (`clone()` is not available on Cygwin and Mac), as `fork()` is more likely
-    to cause the child to hang when the parent process has multiple threads.
-
-It's perfectly fine to create threads inside a death test statement; they are
-executed in a separate process and cannot affect the parent.
-
-### Death Test Styles
-
-
-The "threadsafe" death test style was introduced in order to help mitigate the
-risks of testing in a possibly multithreaded environment. It trades increased
-test execution time (potentially dramatically so) for improved thread safety.
-
-The automated testing framework does not set the style flag. You can choose a
-particular style of death tests by setting the flag programmatically:
-
-```c++
-testing::FLAGS_gtest_death_test_style="threadsafe"
-```
-
-You can do this in `main()` to set the style for all death tests in the binary,
-or in individual tests. Recall that flags are saved before running each test and
-restored afterwards, so you need not do that yourself. For example:
-
-```c++
-int main(int argc, char** argv) {
-  InitGoogle(argv[0], &argc, &argv, true);
-  ::testing::FLAGS_gtest_death_test_style = "fast";
-  return RUN_ALL_TESTS();
-}
-
-TEST(MyDeathTest, TestOne) {
-  ::testing::FLAGS_gtest_death_test_style = "threadsafe";
-  // This test is run in the "threadsafe" style:
-  ASSERT_DEATH(ThisShouldDie(), "");
-}
-
-TEST(MyDeathTest, TestTwo) {
-  // This test is run in the "fast" style:
-  ASSERT_DEATH(ThisShouldDie(), "");
-}
-```
-
-
-### Caveats
-
-The `statement` argument of `ASSERT_EXIT()` can be any valid C++ statement. If
-it leaves the current function via a `return` statement or by throwing an
-exception, the death test is considered to have failed. Some googletest macros
-may return from the current function (e.g. `ASSERT_TRUE()`), so be sure to avoid
-them in `statement`.
-
-Since `statement` runs in the child process, any in-memory side effect (e.g.
-modifying a variable, releasing memory, etc) it causes will *not* be observable
-in the parent process. In particular, if you release memory in a death test,
-your program will fail the heap check as the parent process will never see the
-memory reclaimed. To solve this problem, you can
-
-1.  try not to free memory in a death test;
-2.  free the memory again in the parent process; or
-3.  do not use the heap checker in your program.
-
-Due to an implementation detail, you cannot place multiple death test assertions
-on the same line; otherwise, compilation will fail with an unobvious error
-message.
-
-Despite the improved thread safety afforded by the "threadsafe" style of death
-test, thread problems such as deadlock are still possible in the presence of
-handlers registered with `pthread_atfork(3)`.
-
-
-## Using Assertions in Sub-routines
-
-### Adding Traces to Assertions
-
-If a test sub-routine is called from several places, when an assertion inside it
-fails, it can be hard to tell which invocation of the sub-routine the failure is
-from. 
-You can alleviate this problem using extra logging or custom failure messages,
-but that usually clutters up your tests. A better solution is to use the
-`SCOPED_TRACE` macro or the `ScopedTrace` utility:
-
-```c++
-SCOPED_TRACE(message);
-ScopedTrace trace("file_path", line_number, message);
-```
-
-where `message` can be anything streamable to `std::ostream`. `SCOPED_TRACE`
-macro will cause the current file name, line number, and the given message to be
-added in every failure message. `ScopedTrace` accepts explicit file name and
-line number in arguments, which is useful for writing test helpers. The effect
-will be undone when the control leaves the current lexical scope.
-
-For example,
-
-```c++
-10: void Sub1(int n) {
-11:   EXPECT_EQ(1, Bar(n));
-12:   EXPECT_EQ(2, Bar(n + 1));
-13: }
-14:
-15: TEST(FooTest, Bar) {
-16:   {
-17:     SCOPED_TRACE("A");  // This trace point will be included in
-18:                         // every failure in this scope.
-19:     Sub1(1);
-20:   }
-21:   // Now it won't.
-22:   Sub1(9);
-23: }
-```
-
-could result in messages like these:
-
-```none
-path/to/foo_test.cc:11: Failure
-Value of: Bar(n)
-Expected: 1
-  Actual: 2
-   Trace:
-path/to/foo_test.cc:17: A
-
-path/to/foo_test.cc:12: Failure
-Value of: Bar(n + 1)
-Expected: 2
-  Actual: 3
-```
-
-Without the trace, it would've been difficult to know which invocation of
-`Sub1()` the two failures come from respectively. (You could add
-
-an extra message to each assertion in `Sub1()` to indicate the value of `n`, but
-that's tedious.)
-
-Some tips on using `SCOPED_TRACE`:
-
-1.  With a suitable message, it's often enough to use `SCOPED_TRACE` at the
-    beginning of a sub-routine, instead of at each call site.
-2.  When calling sub-routines inside a loop, make the loop iterator part of the
-    message in `SCOPED_TRACE` such that you can know which iteration the failure
-    is from.
-3.  Sometimes the line number of the trace point is enough for identifying the
-    particular invocation of a sub-routine. In this case, you don't have to
-    choose a unique message for `SCOPED_TRACE`. You can simply use `""`.
-4.  You can use `SCOPED_TRACE` in an inner scope when there is one in the outer
-    scope. In this case, all active trace points will be included in the failure
-    messages, in reverse order they are encountered.
-5.  The trace dump is clickable in Emacs - hit `return` on a line number and
-    you'll be taken to that line in the source file!

-
-### Propagating Fatal Failures
-
-A common pitfall when using `ASSERT_*` and `FAIL*` is not understanding that
-when they fail they only abort the _current function_, not the entire test. For
-example, the following test will segfault:
-
-```c++
-void Subroutine() {
-  // Generates a fatal failure and aborts the current function.
-  ASSERT_EQ(1, 2);
-
-  // The following won't be executed.
-  ...
-}
-
-TEST(FooTest, Bar) {
-  Subroutine();  // The intended behavior is for the fatal failure
-                 // in Subroutine() to abort the entire test.
-
-  // The actual behavior: the function goes on after Subroutine() returns.
-  int* p = NULL;
-  *p = 3;  // Segfault!
-}
-```
-
-To alleviate this, googletest provides three different solutions. You could use
-either exceptions, the `(ASSERT|EXPECT)_NO_FATAL_FAILURE` assertions or the
-`HasFatalFailure()` function. They are described in the following two
-subsections.
-
-#### Asserting on Subroutines with an exception
-
-The following code can turn ASSERT-failure into an exception:
-
-```c++
-class ThrowListener : public testing::EmptyTestEventListener {
-  void OnTestPartResult(const testing::TestPartResult& result) override {
-    if (result.type() == testing::TestPartResult::kFatalFailure) {
-      throw testing::AssertionException(result);
-    }
-  }
-};
-int main(int argc, char** argv) {
-  ...
-  testing::UnitTest::GetInstance()->listeners().Append(new ThrowListener);
-  return RUN_ALL_TESTS();
-}
-```
-
-This listener should be added after other listeners if you have any, otherwise
-they won't see failed `OnTestPartResult`.
-
-#### Asserting on Subroutines
-
-As shown above, if your test calls a subroutine that has an `ASSERT_*` failure
-in it, the test will continue after the subroutine returns. This may not be what
-you want.
-
-Often people want fatal failures to propagate like exceptions. For that
-googletest offers the following macros:
-
-Fatal assertion                       | Nonfatal assertion                    | Verifies
-------------------------------------- | ------------------------------------- | --------
-`ASSERT_NO_FATAL_FAILURE(statement);` | `EXPECT_NO_FATAL_FAILURE(statement);` | `statement` doesn't generate any new fatal failures in the current thread.
-
-Only failures in the thread that executes the assertion are checked to determine
-the result of this type of assertions. If `statement` creates new threads,
-failures in these threads are ignored.
-
-Examples:
-
-```c++
-ASSERT_NO_FATAL_FAILURE(Foo());
-
-int i;
-EXPECT_NO_FATAL_FAILURE({
-  i = Bar();
-});
-```
-
-**Availability**: Linux, Windows, Mac. Assertions from multiple threads are
-currently not supported on Windows.
-
-#### Checking for Failures in the Current Test
-
-`HasFatalFailure()` in the `::testing::Test` class returns `true` if an
-assertion in the current test has suffered a fatal failure. This allows
-functions to catch fatal failures in a sub-routine and return early.
-
-```c++
-class Test {
- public:
-  ...
-  static bool HasFatalFailure();
-};
-```
-
-The typical usage, which basically simulates the behavior of a thrown exception,
-is:
-
-```c++
-TEST(FooTest, Bar) {
-  Subroutine();
-  // Aborts if Subroutine() had a fatal failure.
-  if (HasFatalFailure()) return;
-
-  // The following won't be executed.
-  ...
-}
-```
-
-If `HasFatalFailure()` is used outside of `TEST()` , `TEST_F()` , or a test
-fixture, you must add the `::testing::Test::` prefix, as in:
-
-```c++
-if (::testing::Test::HasFatalFailure()) return;
-```
-
-Similarly, `HasNonfatalFailure()` returns `true` if the current test has at
-least one non-fatal failure, and `HasFailure()` returns `true` if the current
-test has at least one failure of either kind.

-## Logging Additional Information
-
-In your test code, you can call `RecordProperty("key", value)` to log additional
-information, where `value` can be either a string or an `int`. The *last* value
-recorded for a key will be emitted to the [XML output](#generating-an-xml-report) if you
-specify one. For example, the test
-
-```c++
-TEST_F(WidgetUsageTest, MinAndMaxWidgets) {
-  RecordProperty("MaximumWidgets", ComputeMaxUsage());
-  RecordProperty("MinimumWidgets", ComputeMinUsage());
-}
-```
-
-will output XML like this:
-
-```xml
-  ...
-    <testcase name="MinAndMaxWidgets" status="run" time="0.006" classname="WidgetUsageTest" MaximumWidgets="12" MinimumWidgets="9" />
-  ...
-```
-
-> NOTE:
->
-> *   `RecordProperty()` is a static member of the `Test` class. Therefore it
->     needs to be prefixed with `::testing::Test::` if used outside of the
->     `TEST` body and the test fixture class.
-> *   `*key*` must be a valid XML attribute name, and cannot conflict with the
->     ones already used by googletest (`name`, `status`, `time`, `classname`,
->     `type_param`, and `value_param`).
-> *   Calling `RecordProperty()` outside of the lifespan of a test is allowed.
->     If it's called outside of a test but between a test case's
->     `SetUpTestCase()` and `TearDownTestCase()` methods, it will be attributed
->     to the XML element for the test case. If it's called outside of all test
->     cases (e.g. in a test environment), it will be attributed to the top-level
->     XML element.

-## Sharing Resources Between Tests in the Same Test Case
-
-googletest creates a new test fixture object for each test in order to make
-tests independent and easier to debug. However, sometimes tests use resources
-that are expensive to set up, making the one-copy-per-test model prohibitively
-expensive.
-
-If the tests don't change the resource, there's no harm in their sharing a
-single resource copy. So, in addition to per-test set-up/tear-down, googletest
-also supports per-test-case set-up/tear-down. To use it:
-
-1.  In your test fixture class (say `FooTest` ), declare as `static` some member
-    variables to hold the shared resources.
-1.  Outside your test fixture class (typically just below it), define those
-    member variables, optionally giving them initial values.
-1.  In the same test fixture class, define a `static void SetUpTestCase()`
-    function (remember not to spell it as **`SetupTestCase`** with a small `u`!)
-    to set up the shared resources and a `static void TearDownTestCase()`
-    function to tear them down.
-
-That's it! googletest automatically calls `SetUpTestCase()` before running the
-*first test* in the `FooTest` test case (i.e. before creating the first
-`FooTest` object), and calls `TearDownTestCase()` after running the *last test*
-in it (i.e. after deleting the last `FooTest` object). In between, the tests can
-use the shared resources.
-
-Remember that the test order is undefined, so your code can't depend on a test
-preceding or following another. Also, the tests must either not modify the state
-of any shared resource, or, if they do modify the state, they must restore the
-state to its original value before passing control to the next test.
-
-Here's an example of per-test-case set-up and tear-down:
-
-```c++
-class FooTest : public ::testing::Test {
- protected:
-  // Per-test-case set-up.
-  // Called before the first test in this test case.
-  // Can be omitted if not needed.
-  static void SetUpTestCase() {
-    shared_resource_ = new ...;
-  }
-
-  // Per-test-case tear-down.
-  // Called after the last test in this test case.
-  // Can be omitted if not needed.
-  static void TearDownTestCase() {
-    delete shared_resource_;
-    shared_resource_ = NULL;
-  }
-
-  // You can define per-test set-up logic as usual.
-  virtual void SetUp() { ... }
-
-  // You can define per-test tear-down logic as usual.
-  virtual void TearDown() { ... }
-
-  // Some expensive resource shared by all tests.
-  static T* shared_resource_;
-};
-
-T* FooTest::shared_resource_ = NULL;
-
-TEST_F(FooTest, Test1) {
-  ... you can refer to shared_resource_ here ...
-}
-
-TEST_F(FooTest, Test2) {
-  ... you can refer to shared_resource_ here ...
-}
-```
-
-NOTE: Though the above code declares `SetUpTestCase()` protected, it may
-sometimes be necessary to declare it public, such as when using it with
-`TEST_P`.
-
-**Availability**: Linux, Windows, Mac.
-
-## Global Set-Up and Tear-Down
-
-Just as you can do set-up and tear-down at the test level and the test case
-level, you can also do it at the test program level. Here's how.
-
-First, you subclass the `::testing::Environment` class to define a test
-environment, which knows how to set-up and tear-down:
-
-```c++
-class Environment {
- public:
-  virtual ~Environment() {}
-
-  // Override this to define how to set up the environment.
-  virtual void SetUp() {}
-
-  // Override this to define how to tear down the environment.
-  virtual void TearDown() {}
-};
-```
-
-Then, you register an instance of your environment class with googletest by
-calling the `::testing::AddGlobalTestEnvironment()` function:
-
-```c++
-Environment* AddGlobalTestEnvironment(Environment* env);
-```
-
-Now, when `RUN_ALL_TESTS()` is called, it first calls the `SetUp()` method of
-the environment object, then runs the tests if there was no fatal failures, and
-finally calls `TearDown()` of the environment object.
-
-It's OK to register multiple environment objects. In this case, their `SetUp()`
-will be called in the order they are registered, and their `TearDown()` will be
-called in the reverse order.
-
-Note that googletest takes ownership of the registered environment objects.
-Therefore **do not delete them** by yourself.
-
-You should call `AddGlobalTestEnvironment()` before `RUN_ALL_TESTS()` is called,
-probably in `main()`. If you use `gtest_main`, you need to call this before
-`main()` starts for it to take effect. One way to do this is to define a global
-variable like this:
-
-```c++
-::testing::Environment* const foo_env =
-    ::testing::AddGlobalTestEnvironment(new FooEnvironment);
-```
-
-However, we strongly recommend you to write your own `main()` and call
-`AddGlobalTestEnvironment()` there, as relying on initialization of global
-variables makes the code harder to read and may cause problems when you register
-multiple environments from different translation units and the environments have
-dependencies among them (remember that the compiler doesn't guarantee the order
-in which global variables from different translation units are initialized).
-
-## Value-Parameterized Tests
-
-*Value-parameterized tests* allow you to test your code with different
-parameters without writing multiple copies of the same test. This is useful in a
-number of situations, for example:
-
-*   You have a piece of code whose behavior is affected by one or more
-    command-line flags. You want to make sure your code performs correctly for
-    various values of those flags.
-*   You want to test different implementations of an OO interface.
-*   You want to test your code over various inputs (a.k.a. data-driven testing).
-    This feature is easy to abuse, so please exercise your good sense when doing
-    it!
-
-### How to Write Value-Parameterized Tests
-
-To write value-parameterized tests, first you should define a fixture class. It
-must be derived from both `::testing::Test` and
-`::testing::WithParamInterface<T>` (the latter is a pure interface), where `T`
-is the type of your parameter values. For convenience, you can just derive the
-fixture class from `::testing::TestWithParam<T>`, which itself is derived from
-both `::testing::Test` and `::testing::WithParamInterface<T>`. `T` can be any
-copyable type. If it's a raw pointer, you are responsible for managing the
-lifespan of the pointed values.
-
-NOTE: If your test fixture defines `SetUpTestCase()` or `TearDownTestCase()`
-they must be declared **public** rather than **protected** in order to use
-`TEST_P`.
-
-```c++
-class FooTest :
-    public ::testing::TestWithParam<const char*> {
-  // You can implement all the usual fixture class members here.
-  // To access the test parameter, call GetParam() from class
-  // TestWithParam<T>.
-};
-
-// Or, when you want to add parameters to a pre-existing fixture class:
-class BaseTest : public ::testing::Test {
-  ...
-};
-class BarTest : public BaseTest,
-                public ::testing::WithParamInterface<const char*> {
-  ...
-};
-```
-
-Then, use the `TEST_P` macro to define as many test patterns using this fixture
-as you want. The `_P` suffix is for "parameterized" or "pattern", whichever you
-prefer to think.
-
-```c++
-TEST_P(FooTest, DoesBlah) {
-  // Inside a test, access the test parameter with the GetParam() method
-  // of the TestWithParam<T> class:
-  EXPECT_TRUE(foo.Blah(GetParam()));
-  ...
-}
-
-TEST_P(FooTest, HasBlahBlah) {
-  ...
-}
-```
-
-Finally, you can use `INSTANTIATE_TEST_CASE_P` to instantiate the test case with
-any set of parameters you want. googletest defines a number of functions for
-generating test parameters. They return what we call (surprise!) *parameter
-generators*. Here is a summary of them, which are all in the `testing`
-namespace:
-
-| Parameter Generator          | Behavior                                    |
-| ---------------------------- | ------------------------------------------- |
-| `Range(begin, end [, step])` | Yields values `{begin, begin+step, begin+step+step, ...}`. The values do not include `end`. `step` defaults to 1.      |
-| `Values(v1, v2, ..., vN)`    | Yields values `{v1, v2, ..., vN}`.          |
-| `ValuesIn(container)` and `ValuesIn(begin,end)`   | Yields values from a C-style array, an STL-style container, or an iterator range  `[begin, end)`. |
-| `Bool()`                     | Yields sequence `{false, true}`.            |
-| `Combine(g1, g2, ..., gN)`   | Yields all combinations (Cartesian product) as std\:\:tuples of the values generated by the `N` generators.            |
-
-For more details, see the comments at the definitions of these functions.
-
-The following statement will instantiate tests from the `FooTest` test case each
-with parameter values `"meeny"`, `"miny"`, and `"moe"`.
-
-```c++
-INSTANTIATE_TEST_CASE_P(InstantiationName,
-                        FooTest,
-                        ::testing::Values("meeny", "miny", "moe"));
-```
-
-NOTE: The code above must be placed at global or namespace scope, not at
-function scope.
-
-NOTE: Don't forget this step! If you do your test will silently pass, but none
-of its cases will ever run!
-
-To distinguish different instances of the pattern (yes, you can instantiate it
-more than once), the first argument to `INSTANTIATE_TEST_CASE_P` is a prefix
-that will be added to the actual test case name. Remember to pick unique
-prefixes for different instantiations. The tests from the instantiation above
-will have these names:
-
-*   `InstantiationName/FooTest.DoesBlah/0` for `"meeny"`
-*   `InstantiationName/FooTest.DoesBlah/1` for `"miny"`
-*   `InstantiationName/FooTest.DoesBlah/2` for `"moe"`
-*   `InstantiationName/FooTest.HasBlahBlah/0` for `"meeny"`
-*   `InstantiationName/FooTest.HasBlahBlah/1` for `"miny"`
-*   `InstantiationName/FooTest.HasBlahBlah/2` for `"moe"`
-
-You can use these names in [`--gtest_filter`](#running-a-subset-of-the-tests).
-
-This statement will instantiate all tests from `FooTest` again, each with
-parameter values `"cat"` and `"dog"`:
-
-```c++
-const char* pets[] = {"cat", "dog"};
-INSTANTIATE_TEST_CASE_P(AnotherInstantiationName, FooTest,
-                        ::testing::ValuesIn(pets));
-```
-
-The tests from the instantiation above will have these names:
-
-*   `AnotherInstantiationName/FooTest.DoesBlah/0` for `"cat"`
-*   `AnotherInstantiationName/FooTest.DoesBlah/1` for `"dog"`
-*   `AnotherInstantiationName/FooTest.HasBlahBlah/0` for `"cat"`
-*   `AnotherInstantiationName/FooTest.HasBlahBlah/1` for `"dog"`
-
-Please note that `INSTANTIATE_TEST_CASE_P` will instantiate *all* tests in the
-given test case, whether their definitions come before or *after* the
-`INSTANTIATE_TEST_CASE_P` statement.

-
-### Creating Value-Parameterized Abstract Tests
-
-In the above, we define and instantiate `FooTest` in the *same* source file.
-Sometimes you may want to define value-parameterized tests in a library and let
-other people instantiate them later. This pattern is known as *abstract tests*.
-As an example of its application, when you are designing an interface you can
-write a standard suite of abstract tests (perhaps using a factory function as
-the test parameter) that all implementations of the interface are expected to
-pass. When someone implements the interface, they can instantiate your suite to
-get all the interface-conformance tests for free.
-
-To define abstract tests, you should organize your code like this:
-
-1.  Put the definition of the parameterized test fixture class (e.g. `FooTest`)
-    in a header file, say `foo_param_test.h`. Think of this as *declaring* your
-    abstract tests.
-1.  Put the `TEST_P` definitions in `foo_param_test.cc`, which includes
-    `foo_param_test.h`. Think of this as *implementing* your abstract tests.
-
-Once they are defined, you can instantiate them by including `foo_param_test.h`,
-invoking `INSTANTIATE_TEST_CASE_P()`, and depending on the library target that
-contains `foo_param_test.cc`. You can instantiate the same abstract test case
-multiple times, possibly in different source files.
-
-### Specifying Names for Value-Parameterized Test Parameters
-
-The optional last argument to `INSTANTIATE_TEST_CASE_P()` allows the user to
-specify a function or functor that generates custom test name suffixes based on
-the test parameters. The function should accept one argument of type
-`testing::TestParamInfo<class ParamType>`, and return `std::string`.
-
-`testing::PrintToStringParamName` is a builtin test suffix generator that
-returns the value of `testing::PrintToString(GetParam())`. It does not work for
-`std::string` or C strings.
-
-NOTE: test names must be non-empty, unique, and may only contain ASCII
-alphanumeric characters. In particular, they [should not contain
-underscores](https://g3doc.corp.google.com/third_party/googletest/googletest/g3doc/faq.md#no-underscores).
-
-```c++
-class MyTestCase : public testing::TestWithParam<int> {};
-
-TEST_P(MyTestCase, MyTest)
-{
-  std::cout << "Example Test Param: " << GetParam() << std::endl;
-}
-
-INSTANTIATE_TEST_CASE_P(MyGroup, MyTestCase, testing::Range(0, 10),
-                        testing::PrintToStringParamName());
-```
-
-## Typed Tests</id>
-
-Suppose you have multiple implementations of the same interface and want to make
-sure that all of them satisfy some common requirements. Or, you may have defined
-several types that are supposed to conform to the same "concept" and you want to
-verify it. In both cases, you want the same test logic repeated for different
-types.
-
-While you can write one `TEST` or `TEST_F` for each type you want to test (and
-you may even factor the test logic into a function template that you invoke from
-the `TEST`), it's tedious and doesn't scale: if you want `m` tests over `n`
-types, you'll end up writing `m*n` `TEST`s.
-
-*Typed tests* allow you to repeat the same test logic over a list of types. You
-only need to write the test logic once, although you must know the type list
-when writing typed tests. Here's how you do it:
-
-First, define a fixture class template. It should be parameterized by a type.
-Remember to derive it from `::testing::Test`:
-
-```c++
-template <typename T>
-class FooTest : public ::testing::Test {
- public:
-  ...
-  typedef std::list<T> List;
-  static T shared_;
-  T value_;
-};
-```
-
-Next, associate a list of types with the test case, which will be repeated for
-each type in the list:
-
-```c++
-using MyTypes = ::testing::Types<char, int, unsigned int>;
-TYPED_TEST_CASE(FooTest, MyTypes);
-```
-
-The type alias (`using` or `typedef`) is necessary for the `TYPED_TEST_CASE`
-macro to parse correctly. Otherwise the compiler will think that each comma in
-the type list introduces a new macro argument.
-
-Then, use `TYPED_TEST()` instead of `TEST_F()` to define a typed test for this
-test case. You can repeat this as many times as you want:
-
-```c++
-TYPED_TEST(FooTest, DoesBlah) {
-  // Inside a test, refer to the special name TypeParam to get the type
-  // parameter.  Since we are inside a derived class template, C++ requires
-  // us to visit the members of FooTest via 'this'.
-  TypeParam n = this->value_;
-
-  // To visit static members of the fixture, add the 'TestFixture::'
-  // prefix.
-  n += TestFixture::shared_;
-
-  // To refer to typedefs in the fixture, add the 'typename TestFixture::'
-  // prefix.  The 'typename' is required to satisfy the compiler.
-  typename TestFixture::List values;
-
-  values.push_back(n);
-  ...
-}
-
-TYPED_TEST(FooTest, HasPropertyA) { ... }
-```

-
-## Type-Parameterized Tests
-
-*Type-parameterized tests* are like typed tests, except that they don't require
-you to know the list of types ahead of time. Instead, you can define the test
-logic first and instantiate it with different type lists later. You can even
-instantiate it more than once in the same program.
-
-If you are designing an interface or concept, you can define a suite of
-type-parameterized tests to verify properties that any valid implementation of
-the interface/concept should have. Then, the author of each implementation can
-just instantiate the test suite with their type to verify that it conforms to
-the requirements, without having to write similar tests repeatedly. Here's an
-example:
-
-First, define a fixture class template, as we did with typed tests:
-
-```c++
-template <typename T>
-class FooTest : public ::testing::Test {
-  ...
-};
-```
-
-Next, declare that you will define a type-parameterized test case:
-
-```c++
-TYPED_TEST_CASE_P(FooTest);
-```
-
-Then, use `TYPED_TEST_P()` to define a type-parameterized test. You can repeat
-this as many times as you want:
-
-```c++
-TYPED_TEST_P(FooTest, DoesBlah) {
-  // Inside a test, refer to TypeParam to get the type parameter.
-  TypeParam n = 0;
-  ...
-}
-
-TYPED_TEST_P(FooTest, HasPropertyA) { ... }
-```
-
-Now the tricky part: you need to register all test patterns using the
-`REGISTER_TYPED_TEST_CASE_P` macro before you can instantiate them. The first
-argument of the macro is the test case name; the rest are the names of the tests
-in this test case:
-
-```c++
-REGISTER_TYPED_TEST_CASE_P(FooTest,
-                           DoesBlah, HasPropertyA);
-```
-
-Finally, you are free to instantiate the pattern with the types you want. If you
-put the above code in a header file, you can `#include` it in multiple C++
-source files and instantiate it multiple times.
-
-```c++
-typedef ::testing::Types<char, int, unsigned int> MyTypes;
-INSTANTIATE_TYPED_TEST_CASE_P(My, FooTest, MyTypes);
-```
-
-To distinguish different instances of the pattern, the first argument to the
-`INSTANTIATE_TYPED_TEST_CASE_P` macro is a prefix that will be added to the
-actual test case name. Remember to pick unique prefixes for different instances.
-
-In the special case where the type list contains only one type, you can write
-that type directly without `::testing::Types<...>`, like this:
-
-```c++
-INSTANTIATE_TYPED_TEST_CASE_P(My, FooTest, int);
-```
-
-You can see `sample6_unittest.cc` for a complete example.

-## Testing Private Code
-
-If you change your software's internal implementation, your tests should not
-break as long as the change is not observable by users. Therefore, **per the
-black-box testing principle, most of the time you should test your code through
-its public interfaces.**
-
-**If you still find yourself needing to test internal implementation code,
-consider if there's a better design.** The desire to test internal
-implementation is often a sign that the class is doing too much. Consider
-extracting an implementation class, and testing it. Then use that implementation
-class in the original class.
-
-If you absolutely have to test non-public interface code though, you can. There
-are two cases to consider:
-
-*   Static functions ( *not* the same as static member functions!) or unnamed
-    namespaces, and
-*   Private or protected class members
-
-To test them, we use the following special techniques:
-
-*   Both static functions and definitions/declarations in an unnamed namespace
-    are only visible within the same translation unit. To test them, you can
-    `#include` the entire `.cc` file being tested in your `*_test.cc` file.
-    (including `.cc` files is not a good way to reuse code - you should not do
-    this in production code!)
-
-    However, a better approach is to move the private code into the
-    `foo::internal` namespace, where `foo` is the namespace your project
-    normally uses, and put the private declarations in a `*-internal.h` file.
-    Your production `.cc` files and your tests are allowed to include this
-    internal header, but your clients are not. This way, you can fully test your
-    internal implementation without leaking it to your clients.
-
-*   Private class members are only accessible from within the class or by
-    friends. To access a class' private members, you can declare your test
-    fixture as a friend to the class and define accessors in your fixture. Tests
-    using the fixture can then access the private members of your production
-    class via the accessors in the fixture. Note that even though your fixture
-    is a friend to your production class, your tests are not automatically
-    friends to it, as they are technically defined in sub-classes of the
-    fixture.
-
-    Another way to test private members is to refactor them into an
-    implementation class, which is then declared in a `*-internal.h` file. Your
-    clients aren't allowed to include this header but your tests can. Such is
-    called the
-    [Pimpl](https://www.gamedev.net/articles/programming/general-and-gameplay-programming/the-c-pimpl-r1794/)
-    (Private Implementation) idiom.
-
-    Or, you can declare an individual test as a friend of your class by adding
-    this line in the class body:
-
-    ```c++
-        FRIEND_TEST(TestCaseName, TestName);
-    ```
-
-    For example,
-
-    ```c++
-    // foo.h
-
-    #include "gtest/gtest_prod.h"
-
-    class Foo {
-      ...
-    private:
-      FRIEND_TEST(FooTest, BarReturnsZeroOnNull);
-
-      int Bar(void* x);
-    };
-
-    // foo_test.cc
-    ...
-    TEST(FooTest, BarReturnsZeroOnNull) {
-      Foo foo;
-      EXPECT_EQ(0, foo.Bar(NULL));  // Uses Foo's private member Bar().
-    }
-    ```
-
-    Pay special attention when your class is defined in a namespace, as you
-    should define your test fixtures and tests in the same namespace if you want
-    them to be friends of your class. For example, if the code to be tested
-    looks like:
-
-    ```c++
-    namespace my_namespace {
-
-    class Foo {
-      friend class FooTest;
-      FRIEND_TEST(FooTest, Bar);
-      FRIEND_TEST(FooTest, Baz);
-      ... definition of the class Foo ...
-    };
-
-    }  // namespace my_namespace
-    ```
-
-    Your test code should be something like:
-
-    ```c++
-    namespace my_namespace {
-
-    class FooTest : public ::testing::Test {
-     protected:
-      ...
-    };
-
-    TEST_F(FooTest, Bar) { ... }
-    TEST_F(FooTest, Baz) { ... }
-
-    }  // namespace my_namespace
-    ```

-The challenge is to verify that your testing utility reports failures correctly.
-In frameworks that report a failure by throwing an exception, you could catch
-the exception and assert on it. But googletest doesn't use exceptions, so how do
-we test that a piece of code generates an expected failure?
-
-gunit-spi.h contains some constructs to do this. After #including this header,
-you can use
-
-```c++
-  EXPECT_FATAL_FAILURE(statement, substring);
-```
-
-to assert that `statement` generates a fatal (e.g. `ASSERT_*`) failure in the
-current thread whose message contains the given `substring`, or use
-
-```c++
-  EXPECT_NONFATAL_FAILURE(statement, substring);
-```
-
-if you are expecting a non-fatal (e.g. `EXPECT_*`) failure.
-
-Only failures in the current thread are checked to determine the result of this
-type of expectations. If `statement` creates new threads, failures in these
-threads are also ignored. If you want to catch failures in other threads as
-well, use one of the following macros instead:
-
-```c++
-  EXPECT_FATAL_FAILURE_ON_ALL_THREADS(statement, substring);
-  EXPECT_NONFATAL_FAILURE_ON_ALL_THREADS(statement, substring);
-```
-
-NOTE: Assertions from multiple threads are currently not supported on Windows.
-
-For technical reasons, there are some caveats:
-
-1.  You cannot stream a failure message to either macro.
-
-1.  `statement` in `EXPECT_FATAL_FAILURE{_ON_ALL_THREADS}()` cannot reference
-    local non-static variables or non-static members of `this` object.
-
-1.  `statement` in `EXPECT_FATAL_FAILURE{_ON_ALL_THREADS}()()` cannot return a
-    value.
-
-
-## Getting the Current Test's Name
-
-Sometimes a function may need to know the name of the currently running test.
-For example, you may be using the `SetUp()` method of your test fixture to set
-the golden file name based on which test is running. The `::testing::TestInfo`
-class has this information:
-
-```c++
-namespace testing {
-
-class TestInfo {
- public:
-  // Returns the test case name and the test name, respectively.
-  //
-  // Do NOT delete or free the return value - it's managed by the
-  // TestInfo class.
-  const char* test_case_name() const;
-  const char* name() const;
-};
-
-}
-```
-
-To obtain a `TestInfo` object for the currently running test, call
-`current_test_info()` on the `UnitTest` singleton object:
-
-```c++
-  // Gets information about the currently running test.
-  // Do NOT delete the returned object - it's managed by the UnitTest class.
-  const ::testing::TestInfo* const test_info =
-    ::testing::UnitTest::GetInstance()->current_test_info();
-
-
-
-  printf("We are in test %s of test case %s.\n",
-         test_info->name(),
-         test_info->test_case_name());
-```
-
-`current_test_info()` returns a null pointer if no test is running. In
-particular, you cannot find the test case name in `TestCaseSetUp()`,
-`TestCaseTearDown()` (where you know the test case name implicitly), or
-functions called from them.

-
-## Extending googletest by Handling Test Events
-
-googletest provides an **event listener API** to let you receive notifications
-about the progress of a test program and test failures. The events you can
-listen to include the start and end of the test program, a test case, or a test
-method, among others. You may use this API to augment or replace the standard
-console output, replace the XML output, or provide a completely different form
-of output, such as a GUI or a database. You can also use test events as
-checkpoints to implement a resource leak checker, for example.
-
-**Availability**: Linux, Windows, Mac.
-
-### Defining Event Listeners
-
-To define a event listener, you subclass either testing::TestEventListener or
-testing::EmptyTestEventListener The former is an (abstract) interface, where
-*each pure virtual method can be overridden to handle a test event* (For
-example, when a test starts, the `OnTestStart()` method will be called.). The
-latter provides an empty implementation of all methods in the interface, such
-that a subclass only needs to override the methods it cares about.
-
-When an event is fired, its context is passed to the handler function as an
-argument. The following argument types are used:
-
-*   UnitTest reflects the state of the entire test program,
-*   TestCase has information about a test case, which can contain one or more
-    tests,
-*   TestInfo contains the state of a test, and
-*   TestPartResult represents the result of a test assertion.
-
-An event handler function can examine the argument it receives to find out
-interesting information about the event and the test program's state.
-
-Here's an example:
-
-```c++
-  class MinimalistPrinter : public ::testing::EmptyTestEventListener {
-    // Called before a test starts.
-    virtual void OnTestStart(const ::testing::TestInfo& test_info) {
-      printf("*** Test %s.%s starting.\n",
-             test_info.test_case_name(), test_info.name());
-    }
-
-    // Called after a failed assertion or a SUCCESS().
-    virtual void OnTestPartResult(const ::testing::TestPartResult& test_part_result) {
-      printf("%s in %s:%d\n%s\n",
-             test_part_result.failed() ? "*** Failure" : "Success",
-             test_part_result.file_name(),
-             test_part_result.line_number(),
-             test_part_result.summary());
-    }
-
-    // Called after a test ends.
-    virtual void OnTestEnd(const ::testing::TestInfo& test_info) {
-      printf("*** Test %s.%s ending.\n",
-             test_info.test_case_name(), test_info.name());
-    }
-  };
-```
-
-### Using Event Listeners
-
-To use the event listener you have defined, add an instance of it to the
-googletest event listener list (represented by class TestEventListeners - note
-the "s" at the end of the name) in your `main()` function, before calling
-`RUN_ALL_TESTS()`:
-
-```c++
-int main(int argc, char** argv) {
-  ::testing::InitGoogleTest(&argc, argv);
-  // Gets hold of the event listener list.
-  ::testing::TestEventListeners& listeners =
-        ::testing::UnitTest::GetInstance()->listeners();
-  // Adds a listener to the end.  googletest takes the ownership.
-  listeners.Append(new MinimalistPrinter);
-  return RUN_ALL_TESTS();
-}
-```
-
-There's only one problem: the default test result printer is still in effect, so
-its output will mingle with the output from your minimalist printer. To suppress
-the default printer, just release it from the event listener list and delete it.
-You can do so by adding one line:
-
-```c++
-  ...
-  delete listeners.Release(listeners.default_result_printer());
-  listeners.Append(new MinimalistPrinter);
-  return RUN_ALL_TESTS();
-```
-
-Now, sit back and enjoy a completely different output from your tests. For more
-details, you can read this sample9_unittest.cc
-
-You may append more than one listener to the list. When an `On*Start()` or
-`OnTestPartResult()` event is fired, the listeners will receive it in the order
-they appear in the list (since new listeners are added to the end of the list,
-the default text printer and the default XML generator will receive the event
-first). An `On*End()` event will be received by the listeners in the *reverse*
-order. This allows output by listeners added later to be framed by output from
-listeners added earlier.
-
-### Generating Failures in Listeners
-
-You may use failure-raising macros (`EXPECT_*()`, `ASSERT_*()`, `FAIL()`, etc)
-when processing an event. There are some restrictions:
-
-1.  You cannot generate any failure in `OnTestPartResult()` (otherwise it will
-    cause `OnTestPartResult()` to be called recursively).
-1.  A listener that handles `OnTestPartResult()` is not allowed to generate any
-    failure.
-
-When you add listeners to the listener list, you should put listeners that
-handle `OnTestPartResult()` *before* listeners that can generate failures. This
-ensures that failures generated by the latter are attributed to the right test
-by the former.
-
-We have a sample of failure-raising listener sample10_unittest.cc
-
-## Running Test Programs: Advanced Options
-
-googletest test programs are ordinary executables. Once built, you can run them
-directly and affect their behavior via the following environment variables
-and/or command line flags. For the flags to work, your programs must call
-`::testing::InitGoogleTest()` before calling `RUN_ALL_TESTS()`.
-
-To see a list of supported flags and their usage, please run your test program
-with the `--help` flag. You can also use `-h`, `-?`, or `/?` for short.
-
-If an option is specified both by an environment variable and by a flag, the
-latter takes precedence.
-
-### Selecting Tests
-
-#### Listing Test Names
-
-Sometimes it is necessary to list the available tests in a program before
-running them so that a filter may be applied if needed. Including the flag
-`--gtest_list_tests` overrides all other flags and lists tests in the following
-format:
-
-```none
-TestCase1.
-  TestName1
-  TestName2
-TestCase2.
-  TestName
-```
-
-None of the tests listed are actually run if the flag is provided. There is no
-corresponding environment variable for this flag.
-
-**Availability**: Linux, Windows, Mac.
-
-#### Running a Subset of the Tests
-
-By default, a googletest program runs all tests the user has defined. Sometimes,
-you want to run only a subset of the tests (e.g. for debugging or quickly
-verifying a change). If you set the `GTEST_FILTER` environment variable or the
-`--gtest_filter` flag to a filter string, googletest will only run the tests
-whose full names (in the form of `TestCaseName.TestName`) match the filter.
-
-The format of a filter is a '`:`'-separated list of wildcard patterns (called
-the *positive patterns*) optionally followed by a '`-`' and another
-'`:`'-separated pattern list (called the *negative patterns*). A test matches
-the filter if and only if it matches any of the positive patterns but does not
-match any of the negative patterns.
-
-A pattern may contain `'*'` (matches any string) or `'?'` (matches any single
-character). For convenience, the filter
-
-`'*-NegativePatterns'` can be also written as `'-NegativePatterns'`.
-
-For example:
-
-*   `./foo_test` Has no flag, and thus runs all its tests.
-*   `./foo_test --gtest_filter=*` Also runs everything, due to the single
-    match-everything `*` value.
-*   `./foo_test --gtest_filter=FooTest.*` Runs everything in test case `FooTest`
-    .
-*   `./foo_test --gtest_filter=*Null*:*Constructor*` Runs any test whose full
-    name contains either `"Null"` or `"Constructor"` .
-*   `./foo_test --gtest_filter=-*DeathTest.*` Runs all non-death tests.
-*   `./foo_test --gtest_filter=FooTest.*-FooTest.Bar` Runs everything in test
-    case `FooTest` except `FooTest.Bar`.
-*   `./foo_test --gtest_filter=FooTest.*:BarTest.*-FooTest.Bar:BarTest.Foo` Runs
-    everything in test case `FooTest` except `FooTest.Bar` and everything in
-    test case `BarTest` except `BarTest.Foo`.
-    
-#### Temporarily Disabling Tests
-
-If you have a broken test that you cannot fix right away, you can add the
-`DISABLED_` prefix to its name. This will exclude it from execution. This is
-better than commenting out the code or using `#if 0`, as disabled tests are
-still compiled (and thus won't rot).
-
-If you need to disable all tests in a test case, you can either add `DISABLED_`
-to the front of the name of each test, or alternatively add it to the front of
-the test case name.
-
-For example, the following tests won't be run by googletest, even though they
-will still be compiled:
-
-```c++
-// Tests that Foo does Abc.
-TEST(FooTest, DISABLED_DoesAbc) { ... }
-
-class DISABLED_BarTest : public ::testing::Test { ... };
-
-// Tests that Bar does Xyz.
-TEST_F(DISABLED_BarTest, DoesXyz) { ... }
-```
-
-NOTE: This feature should only be used for temporary pain-relief. You still have
-to fix the disabled tests at a later date. As a reminder, googletest will print
-a banner warning you if a test program contains any disabled tests.
-
-TIP: You can easily count the number of disabled tests you have using `gsearch`
-and/or `grep`. This number can be used as a metric for improving your test
-quality.
-
-**Availability**: Linux, Windows, Mac.
-
-#### Temporarily Enabling Disabled Tests
-
-To include disabled tests in test execution, just invoke the test program with
-the `--gtest_also_run_disabled_tests` flag or set the
-`GTEST_ALSO_RUN_DISABLED_TESTS` environment variable to a value other than `0`.
-You can combine this with the `--gtest_filter` flag to further select which
-disabled tests to run.
-
-**Availability**: Linux, Windows, Mac.
-
-### Repeating the Tests
-
-Once in a while you'll run into a test whose result is hit-or-miss. Perhaps it
-will fail only 1% of the time, making it rather hard to reproduce the bug under
-a debugger. This can be a major source of frustration.
-
-The `--gtest_repeat` flag allows you to repeat all (or selected) test methods in
-a program many times. Hopefully, a flaky test will eventually fail and give you
-a chance to debug. Here's how to use it:
-
-```none
-$ foo_test --gtest_repeat=1000
-Repeat foo_test 1000 times and don't stop at failures.
-
-$ foo_test --gtest_repeat=-1
-A negative count means repeating forever.
-
-$ foo_test --gtest_repeat=1000 --gtest_break_on_failure
-Repeat foo_test 1000 times, stopping at the first failure.  This
-is especially useful when running under a debugger: when the test
-fails, it will drop into the debugger and you can then inspect
-variables and stacks.
-
-$ foo_test --gtest_repeat=1000 --gtest_filter=FooBar.*
-Repeat the tests whose name matches the filter 1000 times.
-```
-
-If your test program contains [global set-up/tear-down](#global-set-up-and-tear-down) code, it
-will be repeated in each iteration as well, as the flakiness may be in it. You
-can also specify the repeat count by setting the `GTEST_REPEAT` environment
-variable.
-
-**Availability**: Linux, Windows, Mac.
-
-### Shuffling the Tests
-
-You can specify the `--gtest_shuffle` flag (or set the `GTEST_SHUFFLE`
-environment variable to `1`) to run the tests in a program in a random order.
-This helps to reveal bad dependencies between tests.
-
-By default, googletest uses a random seed calculated from the current time.
-Therefore you'll get a different order every time. The console output includes
-the random seed value, such that you can reproduce an order-related test failure
-later. To specify the random seed explicitly, use the `--gtest_random_seed=SEED`
-flag (or set the `GTEST_RANDOM_SEED` environment variable), where `SEED` is an
-integer in the range [0, 99999]. The seed value 0 is special: it tells
-googletest to do the default behavior of calculating the seed from the current
-time.
-
-If you combine this with `--gtest_repeat=N`, googletest will pick a different
-random seed and re-shuffle the tests in each iteration.
-
-**Availability**: Linux, Windows, Mac.
-
-### Controlling Test Output
-
-#### Colored Terminal Output
-
-googletest can use colors in its terminal output to make it easier to spot the
-important information:
-
-...<br/>
-<span style="color:green">[----------]<span style="color:black"> 1 test from FooTest<br/>
-<span style="color:green">[ RUN      ]<span style="color:black"> FooTest.DoesAbc<br/>
-<span style="color:green">[       OK ]<span style="color:black"> FooTest.DoesAbc<br/>
-<span style="color:green">[----------]<span style="color:black"> 2 tests from BarTest<br/>
-<span style="color:green">[ RUN      ]<span style="color:black"> BarTest.HasXyzProperty<br/>
-<span style="color:green">[       OK ]<span style="color:black"> BarTest.HasXyzProperty<br/>
-<span style="color:green">[ RUN      ]<span style="color:black"> BarTest.ReturnsTrueOnSuccess<br/>
-... some error messages ...<br/>
-<span   style="color:red">[  FAILED  ] <span style="color:black">BarTest.ReturnsTrueOnSuccess<br/>
-...<br/>
-<span style="color:green">[==========]<span style="color:black"> 30 tests from 14 test cases ran.<br/>
-<span style="color:green">[  PASSED  ]<span style="color:black"> 28 tests.<br/>
-<span style="color:red">[  FAILED  ]<span style="color:black"> 2 tests, listed below:<br/>
-<span style="color:red">[  FAILED  ]<span style="color:black"> BarTest.ReturnsTrueOnSuccess<br/>
-<span style="color:red">[  FAILED  ]<span style="color:black"> AnotherTest.DoesXyz<br/>
-  2 FAILED TESTS
-
-You can set the `GTEST_COLOR` environment variable or the `--gtest_color`
-command line flag to `yes`, `no`, or `auto` (the default) to enable colors,
-disable colors, or let googletest decide. When the value is `auto`, googletest
-will use colors if and only if the output goes to a terminal and (on non-Windows
-platforms) the `TERM` environment variable is set to `xterm` or `xterm-color`.
-
- **Availability**: Linux, Windows, Mac.
-
-#### Suppressing the Elapsed Time
-
-By default, googletest prints the time it takes to run each test. To disable
-that, run the test program with the `--gtest_print_time=0` command line flag, or
-set the GTEST_PRINT_TIME environment variable to `0`.
-
-**Availability**: Linux, Windows, Mac.
-
-#### Suppressing UTF-8 Text Output
-
-In case of assertion failures, googletest prints expected and actual values of
-type `string` both as hex-encoded strings as well as in readable UTF-8 text if
-they contain valid non-ASCII UTF-8 characters. If you want to suppress the UTF-8
-text because, for example, you don't have an UTF-8 compatible output medium, run
-the test program with `--gtest_print_utf8=0` or set the `GTEST_PRINT_UTF8`
-environment variable to `0`.
-
-**Availability**: Linux, Windows, Mac.
-
-
-#### Generating an XML Report
-
-googletest can emit a detailed XML report to a file in addition to its normal
-textual output. The report contains the duration of each test, and thus can help
-you identify slow tests. The report is also used by the http://unittest
-dashboard to show per-test-method error messages.
-
-To generate the XML report, set the `GTEST_OUTPUT` environment variable or the
-`--gtest_output` flag to the string `"xml:path_to_output_file"`, which will
-create the file at the given location. You can also just use the string `"xml"`,
-in which case the output can be found in the `test_detail.xml` file in the
-current directory.
-
-If you specify a directory (for example, `"xml:output/directory/"` on Linux or
-`"xml:output\directory\"` on Windows), googletest will create the XML file in
-that directory, named after the test executable (e.g. `foo_test.xml` for test
-program `foo_test` or `foo_test.exe`). If the file already exists (perhaps left
-over from a previous run), googletest will pick a different name (e.g.
-`foo_test_1.xml`) to avoid overwriting it.
-
-
-The report is based on the `junitreport` Ant task. Since that format was
-originally intended for Java, a little interpretation is required to make it
-apply to googletest tests, as shown here:
-
-```xml
-<testsuites name="AllTests" ...>
-  <testsuite name="test_case_name" ...>
-    <testcase    name="test_name" ...>
-      <failure message="..."/>
-      <failure message="..."/>
-      <failure message="..."/>
-    </testcase>
-  </testsuite>
-</testsuites>
-```
-
-*   The root `<testsuites>` element corresponds to the entire test program.
-*   `<testsuite>` elements correspond to googletest test cases.
-*   `<testcase>` elements correspond to googletest test functions.
-
-For instance, the following program
-
-```c++
-TEST(MathTest, Addition) { ... }
-TEST(MathTest, Subtraction) { ... }
-TEST(LogicTest, NonContradiction) { ... }
-```
-
-could generate this report:
-
-```xml
-<?xml version="1.0" encoding="UTF-8"?>
-<testsuites tests="3" failures="1" errors="0" time="0.035" timestamp="2011-10-31T18:52:42" name="AllTests">
-  <testsuite name="MathTest" tests="2" failures="1" errors="0" time="0.015">
-    <testcase name="Addition" status="run" time="0.007" classname="">
-      <failure message="Value of: add(1, 1)&#x0A;  Actual: 3&#x0A;Expected: 2" type="">...</failure>
-      <failure message="Value of: add(1, -1)&#x0A;  Actual: 1&#x0A;Expected: 0" type="">...</failure>
-    </testcase>
-    <testcase name="Subtraction" status="run" time="0.005" classname="">
-    </testcase>
-  </testsuite>
-  <testsuite name="LogicTest" tests="1" failures="0" errors="0" time="0.005">
-    <testcase name="NonContradiction" status="run" time="0.005" classname="">
-    </testcase>
-  </testsuite>
-</testsuites>
-```
-
-Things to note:
-
-*   The `tests` attribute of a `<testsuites>` or `<testsuite>` element tells how
-    many test functions the googletest program or test case contains, while the
-    `failures` attribute tells how many of them failed.
-
-*   The `time` attribute expresses the duration of the test, test case, or
-    entire test program in seconds.
-
-*   The `timestamp` attribute records the local date and time of the test
-    execution.
-
-*   Each `<failure>` element corresponds to a single failed googletest
-    assertion.
-
-**Availability**: Linux, Windows, Mac.
-
-#### Generating an JSON Report
-
-googletest can also emit a JSON report as an alternative format to XML. To
-generate the JSON report, set the `GTEST_OUTPUT` environment variable or the
-`--gtest_output` flag to the string `"json:path_to_output_file"`, which will
-create the file at the given location. You can also just use the string
-`"json"`, in which case the output can be found in the `test_detail.json` file
-in the current directory.
-
-The report format conforms to the following JSON Schema:
-
-```json

-### Controlling How Failures Are Reported
-
-#### Turning Assertion Failures into Break-Points
-
-When running test programs under a debugger, it's very convenient if the
-debugger can catch an assertion failure and automatically drop into interactive
-mode. googletest's *break-on-failure* mode supports this behavior.
-
-To enable it, set the `GTEST_BREAK_ON_FAILURE` environment variable to a value
-other than `0` . Alternatively, you can use the `--gtest_break_on_failure`
-command line flag.
-
-**Availability**: Linux, Windows, Mac.
-
-#### Disabling Catching Test-Thrown Exceptions
-
-googletest can be used either with or without exceptions enabled. If a test
-throws a C++ exception or (on Windows) a structured exception (SEH), by default
-googletest catches it, reports it as a test failure, and continues with the next
-test method. This maximizes the coverage of a test run. Also, on Windows an
-uncaught exception will cause a pop-up window, so catching the exceptions allows
-you to run the tests automatically.
-
-When debugging the test failures, however, you may instead want the exceptions
-to be handled by the debugger, such that you can examine the call stack when an
-exception is thrown. To achieve that, set the `GTEST_CATCH_EXCEPTIONS`
-environment variable to `0`, or use the `--gtest_catch_exceptions=0` flag when
-running the tests.
-
-**Availability**: Linux, Windows, Mac.

-# Googletest FAQ
-
-
-## Why should test case names and test names not contain underscore?
-
-Underscore (`_`) is special, as C++ reserves the following to be used by the
-compiler and the standard library:
-
-1.  any identifier that starts with an `_` followed by an upper-case letter, and
-1.  any identifier that contains two consecutive underscores (i.e. `__`)
-    *anywhere* in its name.
-
-User code is *prohibited* from using such identifiers.
-
-Now let's look at what this means for `TEST` and `TEST_F`.
-
-Currently `TEST(TestCaseName, TestName)` generates a class named
-`TestCaseName_TestName_Test`. What happens if `TestCaseName` or `TestName`
-contains `_`?
-
-1.  If `TestCaseName` starts with an `_` followed by an upper-case letter (say,
-    `_Foo`), we end up with `_Foo_TestName_Test`, which is reserved and thus
-    invalid.
-1.  If `TestCaseName` ends with an `_` (say, `Foo_`), we get
-    `Foo__TestName_Test`, which is invalid.
-1.  If `TestName` starts with an `_` (say, `_Bar`), we get
-    `TestCaseName__Bar_Test`, which is invalid.
-1.  If `TestName` ends with an `_` (say, `Bar_`), we get
-    `TestCaseName_Bar__Test`, which is invalid.
-
-So clearly `TestCaseName` and `TestName` cannot start or end with `_` (Actually,
-`TestCaseName` can start with `_` -- as long as the `_` isn't followed by an
-upper-case letter. But that's getting complicated. So for simplicity we just say
-that it cannot start with `_`.).
-
-It may seem fine for `TestCaseName` and `TestName` to contain `_` in the middle.
-However, consider this:
-
-```c++
-TEST(Time, Flies_Like_An_Arrow) { ... }
-TEST(Time_Flies, Like_An_Arrow) { ... }
-```
-
-Now, the two `TEST`s will both generate the same class
-(`Time_Flies_Like_An_Arrow_Test`). That's not good.
-
-So for simplicity, we just ask the users to avoid `_` in `TestCaseName` and
-`TestName`. The rule is more constraining than necessary, but it's simple and
-easy to remember. It also gives googletest some wiggle room in case its
-implementation needs to change in the future.
-
-If you violate the rule, there may not be immediate consequences, but your test
-may (just may) break with a new compiler (or a new version of the compiler you
-are using) or with a new version of googletest. Therefore it's best to follow
-the rule.
-
-## Why does googletest support `EXPECT_EQ(NULL, ptr)` and `ASSERT_EQ(NULL, ptr)` but not `EXPECT_NE(NULL, ptr)` and `ASSERT_NE(NULL, ptr)`?
-
-First of all you can use `EXPECT_NE(nullptr, ptr)` and `ASSERT_NE(nullptr,
-ptr)`. This is the preferred syntax in the style guide because nullptr does not
-have the type problems that NULL does. Which is why NULL does not work.
-
-Due to some peculiarity of C++, it requires some non-trivial template meta
-programming tricks to support using `NULL` as an argument of the `EXPECT_XX()`
-and `ASSERT_XX()` macros. Therefore we only do it where it's most needed
-(otherwise we make the implementation of googletest harder to maintain and more
-error-prone than necessary).
-
-The `EXPECT_EQ()` macro takes the *expected* value as its first argument and the
-*actual* value as the second. It's reasonable that someone wants to write
-`EXPECT_EQ(NULL, some_expression)`, and this indeed was requested several times.
-Therefore we implemented it.
-
-The need for `EXPECT_NE(NULL, ptr)` isn't nearly as strong. When the assertion
-fails, you already know that `ptr` must be `NULL`, so it doesn't add any
-information to print `ptr` in this case. That means `EXPECT_TRUE(ptr != NULL)`
-works just as well.
-
-If we were to support `EXPECT_NE(NULL, ptr)`, for consistency we'll have to
-support `EXPECT_NE(ptr, NULL)` as well, as unlike `EXPECT_EQ`, we don't have a
-convention on the order of the two arguments for `EXPECT_NE`. This means using
-the template meta programming tricks twice in the implementation, making it even
-harder to understand and maintain. We believe the benefit doesn't justify the
-cost.
-
-Finally, with the growth of the gMock matcher library, we are encouraging people
-to use the unified `EXPECT_THAT(value, matcher)` syntax more often in tests. One
-significant advantage of the matcher approach is that matchers can be easily
-combined to form new matchers, while the `EXPECT_NE`, etc, macros cannot be
-easily combined. Therefore we want to invest more in the matchers than in the
-`EXPECT_XX()` macros.
-
-## I need to test that different implementations of an interface satisfy some common requirements. Should I use typed tests or value-parameterized tests?
-
-For testing various implementations of the same interface, either typed tests or
-value-parameterized tests can get it done. It's really up to you the user to
-decide which is more convenient for you, depending on your particular case. Some
-rough guidelines:
-
-*   Typed tests can be easier to write if instances of the different
-    implementations can be created the same way, modulo the type. For example,
-    if all these implementations have a public default constructor (such that
-    you can write `new TypeParam`), or if their factory functions have the same
-    form (e.g. `CreateInstance<TypeParam>()`).
-*   Value-parameterized tests can be easier to write if you need different code
-    patterns to create different implementations' instances, e.g. `new Foo` vs
-    `new Bar(5)`. To accommodate for the differences, you can write factory
-    function wrappers and pass these function pointers to the tests as their
-    parameters.
-*   When a typed test fails, the output includes the name of the type, which can
-    help you quickly identify which implementation is wrong. Value-parameterized
-    tests cannot do this, so there you'll have to look at the iteration number
-    to know which implementation the failure is from, which is less direct.
-*   If you make a mistake writing a typed test, the compiler errors can be
-    harder to digest, as the code is templatized.
-*   When using typed tests, you need to make sure you are testing against the
-    interface type, not the concrete types (in other words, you want to make
-    sure `implicit_cast<MyInterface*>(my_concrete_impl)` works, not just that
-    `my_concrete_impl` works). It's less likely to make mistakes in this area
-    when using value-parameterized tests.
-
-I hope I didn't confuse you more. :-) If you don't mind, I'd suggest you to give
-both approaches a try. Practice is a much better way to grasp the subtle
-differences between the two tools. Once you have some concrete experience, you
-can much more easily decide which one to use the next time.
-
-## My death tests became very slow - what happened?
-
-In August 2008 we had to switch the default death test style from `fast` to
-`threadsafe`, as the former is no longer safe now that threaded logging is the
-default. This caused many death tests to slow down. Unfortunately this change
-was necessary.
-
-Please read [Fixing Failing Death Tests](death_test_styles.md) for what you can
-do.
-
-## I got some run-time errors about invalid proto descriptors when using `ProtocolMessageEquals`. Help!
-
-**Note:** `ProtocolMessageEquals` and `ProtocolMessageEquiv` are *deprecated*
-now. Please use `EqualsProto`, etc instead.
-
-`ProtocolMessageEquals` and `ProtocolMessageEquiv` were redefined recently and
-are now less tolerant on invalid protocol buffer definitions. In particular, if
-you have a `foo.proto` that doesn't fully qualify the type of a protocol message
-it references (e.g. `message<Bar>` where it should be `message<blah.Bar>`), you
-will now get run-time errors like:
-
-```
-... descriptor.cc:...] Invalid proto descriptor for file "path/to/foo.proto":
-... descriptor.cc:...]  blah.MyMessage.my_field: ".Bar" is not defined.
-```
-
-If you see this, your `.proto` file is broken and needs to be fixed by making
-the types fully qualified. The new definition of `ProtocolMessageEquals` and
-`ProtocolMessageEquiv` just happen to reveal your bug.
-
-## My death test modifies some state, but the change seems lost after the death test finishes. Why?
-
-Death tests (`EXPECT_DEATH`, etc) are executed in a sub-process s.t. the
-expected crash won't kill the test program (i.e. the parent process). As a
-result, any in-memory side effects they incur are observable in their respective
-sub-processes, but not in the parent process. You can think of them as running
-in a parallel universe, more or less.
-
-In particular, if you use [gMock](../../googlemock) and the death test statement
-invokes some mock methods, the parent process will think the calls have never
-occurred. Therefore, you may want to move your `EXPECT_CALL` statements inside
-the `EXPECT_DEATH` macro.
-
-## EXPECT_EQ(htonl(blah), blah_blah) generates weird compiler errors in opt mode. Is this a googletest bug?
-
-Actually, the bug is in `htonl()`.
-
-According to `'man htonl'`, `htonl()` is a *function*, which means it's valid to
-use `htonl` as a function pointer. However, in opt mode `htonl()` is defined as
-a *macro*, which breaks this usage.
-
-Worse, the macro definition of `htonl()` uses a `gcc` extension and is *not*
-standard C++. That hacky implementation has some ad hoc limitations. In
-particular, it prevents you from writing `Foo<sizeof(htonl(x))>()`, where `Foo`
-is a template that has an integral argument.
-
-The implementation of `EXPECT_EQ(a, b)` uses `sizeof(... a ...)` inside a
-template argument, and thus doesn't compile in opt mode when `a` contains a call
-to `htonl()`. It is difficult to make `EXPECT_EQ` bypass the `htonl()` bug, as
-the solution must work with different compilers on various platforms.
-
-`htonl()` has some other problems as described in `//util/endian/endian.h`,
-which defines `ghtonl()` to replace it. `ghtonl()` does the same thing `htonl()`
-does, only without its problems. We suggest you to use `ghtonl()` instead of
-`htonl()`, both in your tests and production code.
-
-`//util/endian/endian.h` also defines `ghtons()`, which solves similar problems
-in `htons()`.
-
-Don't forget to add `//util/endian` to the list of dependencies in the `BUILD`
-file wherever `ghtonl()` and `ghtons()` are used. The library consists of a
-single header file and will not bloat your binary.
-
-## The compiler complains about "undefined references" to some static const member variables, but I did define them in the class body. What's wrong?
-
-If your class has a static data member:
-
-```c++
-// foo.h
-class Foo {
-  ...
-  static const int kBar = 100;
-};
-```
-
-You also need to define it *outside* of the class body in `foo.cc`:
-
-```c++
-const int Foo::kBar;  // No initializer here.
-```
-
-Otherwise your code is **invalid C++**, and may break in unexpected ways. In
-particular, using it in googletest comparison assertions (`EXPECT_EQ`, etc) will
-generate an "undefined reference" linker error. The fact that "it used to work"
-doesn't mean it's valid. It just means that you were lucky. :-)
-
-## Can I derive a test fixture from another?
-
-Yes.
-
-Each test fixture has a corresponding and same named test case. This means only
-one test case can use a particular fixture. Sometimes, however, multiple test
-cases may want to use the same or slightly different fixtures. For example, you
-may want to make sure that all of a GUI library's test cases don't leak
-important system resources like fonts and brushes.
-
-In googletest, you share a fixture among test cases by putting the shared logic
-in a base test fixture, then deriving from that base a separate fixture for each
-test case that wants to use this common logic. You then use `TEST_F()` to write
-tests using each derived fixture.
-
-Typically, your code looks like this:
-
-```c++
-// Defines a base test fixture.
-class BaseTest : public ::testing::Test {
- protected:
-  ...
-};
-
-// Derives a fixture FooTest from BaseTest.
-class FooTest : public BaseTest {
- protected:
-  void SetUp() override {
-    BaseTest::SetUp();  // Sets up the base fixture first.
-    ... additional set-up work ...
-  }
-
-  void TearDown() override {
-    ... clean-up work for FooTest ...
-    BaseTest::TearDown();  // Remember to tear down the base fixture
-                           // after cleaning up FooTest!
-  }
-
-  ... functions and variables for FooTest ...
-};
-
-// Tests that use the fixture FooTest.
-TEST_F(FooTest, Bar) { ... }
-TEST_F(FooTest, Baz) { ... }
-
-... additional fixtures derived from BaseTest ...
-```
-
-If necessary, you can continue to derive test fixtures from a derived fixture.
-googletest has no limit on how deep the hierarchy can be.
-
-For a complete example using derived test fixtures, see [googletest
-sample](https://github.com/google/googletest/blob/master/googletest/samples/sample5_unittest.cc)
-
-## My compiler complains "void value not ignored as it ought to be." What does this mean?
-
-You're probably using an `ASSERT_*()` in a function that doesn't return `void`.
-`ASSERT_*()` can only be used in `void` functions, due to exceptions being
-disabled by our build system. Please see more details
-[here](advanced.md#assertion-placement).
-
-## My death test hangs (or seg-faults). How do I fix it?
-
-In googletest, death tests are run in a child process and the way they work is
-delicate. To write death tests you really need to understand how they work.
-Please make sure you have read [this](advanced.md#how-it-works).
-
-In particular, death tests don't like having multiple threads in the parent
-process. So the first thing you can try is to eliminate creating threads outside
-of `EXPECT_DEATH()`. For example, you may want to use [mocks](../../googlemock)
-or fake objects instead of real ones in your tests.
-
-Sometimes this is impossible as some library you must use may be creating
-threads before `main()` is even reached. In this case, you can try to minimize
-the chance of conflicts by either moving as many activities as possible inside
-`EXPECT_DEATH()` (in the extreme case, you want to move everything inside), or
-leaving as few things as possible in it. Also, you can try to set the death test
-style to `"threadsafe"`, which is safer but slower, and see if it helps.
-
-If you go with thread-safe death tests, remember that they rerun the test
-program from the beginning in the child process. Therefore make sure your
-program can run side-by-side with itself and is deterministic.
-
-In the end, this boils down to good concurrent programming. You have to make
-sure that there is no race conditions or dead locks in your program. No silver
-bullet - sorry!
-
-## Should I use the constructor/destructor of the test fixture or SetUp()/TearDown()?
-
-The first thing to remember is that googletest does **not** reuse the same test
-fixture object across multiple tests. For each `TEST_F`, googletest will create
-a **fresh** test fixture object, immediately call `SetUp()`, run the test body,
-call `TearDown()`, and then delete the test fixture object.
-
-When you need to write per-test set-up and tear-down logic, you have the choice
-between using the test fixture constructor/destructor or `SetUp()/TearDown()`.
-The former is usually preferred, as it has the following benefits:
-
-*   By initializing a member variable in the constructor, we have the option to
-    make it `const`, which helps prevent accidental changes to its value and
-    makes the tests more obviously correct.
-*   In case we need to subclass the test fixture class, the subclass'
-    constructor is guaranteed to call the base class' constructor *first*, and
-    the subclass' destructor is guaranteed to call the base class' destructor
-    *afterward*. With `SetUp()/TearDown()`, a subclass may make the mistake of
-    forgetting to call the base class' `SetUp()/TearDown()` or call them at the
-    wrong time.
-
-You may still want to use `SetUp()/TearDown()` in the following rare cases:
-
-*   In the body of a constructor (or destructor), it's not possible to use the
-    `ASSERT_xx` macros. Therefore, if the set-up operation could cause a fatal
-    test failure that should prevent the test from running, it's necessary to
-    use a `CHECK` macro or to use `SetUp()` instead of a constructor.
-*   If the tear-down operation could throw an exception, you must use
-    `TearDown()` as opposed to the destructor, as throwing in a destructor leads
-    to undefined behavior and usually will kill your program right away. Note
-    that many standard libraries (like STL) may throw when exceptions are
-    enabled in the compiler. Therefore you should prefer `TearDown()` if you
-    want to write portable tests that work with or without exceptions.
-*   The googletest team is considering making the assertion macros throw on
-    platforms where exceptions are enabled (e.g. Windows, Mac OS, and Linux
-    client-side), which will eliminate the need for the user to propagate
-    failures from a subroutine to its caller. Therefore, you shouldn't use
-    googletest assertions in a destructor if your code could run on such a
-    platform.
-*   In a constructor or destructor, you cannot make a virtual function call on
-    this object. (You can call a method declared as virtual, but it will be
-    statically bound.) Therefore, if you need to call a method that will be
-    overridden in a derived class, you have to use `SetUp()/TearDown()`.
-
-
-## The compiler complains "no matching function to call" when I use ASSERT_PRED*. How do I fix it?
-
-If the predicate function you use in `ASSERT_PRED*` or `EXPECT_PRED*` is
-overloaded or a template, the compiler will have trouble figuring out which
-overloaded version it should use. `ASSERT_PRED_FORMAT*` and
-`EXPECT_PRED_FORMAT*` don't have this problem.
-
-If you see this error, you might want to switch to
-`(ASSERT|EXPECT)_PRED_FORMAT*`, which will also give you a better failure
-message. If, however, that is not an option, you can resolve the problem by
-explicitly telling the compiler which version to pick.
-
-For example, suppose you have
-
-```c++
-bool IsPositive(int n) {
-  return n > 0;
-}
-
-bool IsPositive(double x) {
-  return x > 0;
-}
-```
-
-you will get a compiler error if you write
-
-```c++
-EXPECT_PRED1(IsPositive, 5);
-```
-
-However, this will work:
-
-```c++
-EXPECT_PRED1(static_cast<bool (*)(int)>(IsPositive), 5);
-```
-
-(The stuff inside the angled brackets for the `static_cast` operator is the type
-of the function pointer for the `int`-version of `IsPositive()`.)
-
-As another example, when you have a template function
-
-```c++
-template <typename T>
-bool IsNegative(T x) {
-  return x < 0;
-}
-```
-
-you can use it in a predicate assertion like this:
-
-```c++
-ASSERT_PRED1(IsNegative<int>, -5);
-```
-
-Things are more interesting if your template has more than one parameters. The
-following won't compile:
-
-```c++
-ASSERT_PRED2(GreaterThan<int, int>, 5, 0);
-```
-
-as the C++ pre-processor thinks you are giving `ASSERT_PRED2` 4 arguments, which
-is one more than expected. The workaround is to wrap the predicate function in
-parentheses:
-
-```c++
-ASSERT_PRED2((GreaterThan<int, int>), 5, 0);
-```
-
-
-## My compiler complains about "ignoring return value" when I call RUN_ALL_TESTS(). Why?
-
-Some people had been ignoring the return value of `RUN_ALL_TESTS()`. That is,
-instead of
-
-```c++
-  return RUN_ALL_TESTS();
-```
-
-they write
-
-```c++
-  RUN_ALL_TESTS();
-```
-
-This is **wrong and dangerous**. The testing services needs to see the return
-value of `RUN_ALL_TESTS()` in order to determine if a test has passed. If your
-`main()` function ignores it, your test will be considered successful even if it
-has a googletest assertion failure. Very bad.
-
-We have decided to fix this (thanks to Michael Chastain for the idea). Now, your
-code will no longer be able to ignore `RUN_ALL_TESTS()` when compiled with
-`gcc`. If you do so, you'll get a compiler error.
-
-If you see the compiler complaining about you ignoring the return value of
-`RUN_ALL_TESTS()`, the fix is simple: just make sure its value is used as the
-return value of `main()`.
-
-But how could we introduce a change that breaks existing tests? Well, in this
-case, the code was already broken in the first place, so we didn't break it. :-)
-
-## My compiler complains that a constructor (or destructor) cannot return a value. What's going on?
-
-Due to a peculiarity of C++, in order to support the syntax for streaming
-messages to an `ASSERT_*`, e.g.
-
-```c++
-  ASSERT_EQ(1, Foo()) << "blah blah" << foo;
-```
-
-we had to give up using `ASSERT*` and `FAIL*` (but not `EXPECT*` and
-`ADD_FAILURE*`) in constructors and destructors. The workaround is to move the
-content of your constructor/destructor to a private void member function, or
-switch to `EXPECT_*()` if that works. This
-[section](advanced.md#assertion-placement) in the user's guide explains it.
-
-## My SetUp() function is not called. Why?
-
-C++ is case-sensitive. Did you spell it as `Setup()`?
-
-Similarly, sometimes people spell `SetUpTestCase()` as `SetupTestCase()` and
-wonder why it's never called.
-
-## How do I jump to the line of a failure in Emacs directly?
-
-googletest's failure message format is understood by Emacs and many other IDEs,
-like acme and XCode. If a googletest message is in a compilation buffer in
-Emacs, then it's clickable.
-
-
-## I have several test cases which share the same test fixture logic, do I have to define a new test fixture class for each of them? This seems pretty tedious.
-
-You don't have to. Instead of
-
-```c++
-class FooTest : public BaseTest {};
-
-TEST_F(FooTest, Abc) { ... }
-TEST_F(FooTest, Def) { ... }
-
-class BarTest : public BaseTest {};
-
-TEST_F(BarTest, Abc) { ... }
-TEST_F(BarTest, Def) { ... }
-```
-
-you can simply `typedef` the test fixtures:
-
-```c++
-typedef BaseTest FooTest;
-
-TEST_F(FooTest, Abc) { ... }
-TEST_F(FooTest, Def) { ... }
-
-typedef BaseTest BarTest;
-
-TEST_F(BarTest, Abc) { ... }
-TEST_F(BarTest, Def) { ... }
-```
-
-## googletest output is buried in a whole bunch of LOG messages. What do I do?
-
-The googletest output is meant to be a concise and human-friendly report. If
-your test generates textual output itself, it will mix with the googletest
-output, making it hard to read. However, there is an easy solution to this
-problem.
-
-Since `LOG` messages go to stderr, we decided to let googletest output go to
-stdout. This way, you can easily separate the two using redirection. For
-example:
-
-```shell
-$ ./my_test > gtest_output.txt
-```
-
-
-## Why should I prefer test fixtures over global variables?
-
-There are several good reasons:
-
-1.  It's likely your test needs to change the states of its global variables.
-    This makes it difficult to keep side effects from escaping one test and
-    contaminating others, making debugging difficult. By using fixtures, each
-    test has a fresh set of variables that's different (but with the same
-    names). Thus, tests are kept independent of each other.
-1.  Global variables pollute the global namespace.
-1.  Test fixtures can be reused via subclassing, which cannot be done easily
-    with global variables. This is useful if many test cases have something in
-    common.
-
-
-    ## What can the statement argument in ASSERT_DEATH() be?
-
-`ASSERT_DEATH(*statement*, *regex*)` (or any death assertion macro) can be used
-wherever `*statement*` is valid. So basically `*statement*` can be any C++
-statement that makes sense in the current context. In particular, it can
-reference global and/or local variables, and can be:
-
-*   a simple function call (often the case),
-*   a complex expression, or
-*   a compound statement.
-
-Some examples are shown here:
-
-```c++
-// A death test can be a simple function call.
-TEST(MyDeathTest, FunctionCall) {
-  ASSERT_DEATH(Xyz(5), "Xyz failed");
-}
-
-// Or a complex expression that references variables and functions.
-TEST(MyDeathTest, ComplexExpression) {
-  const bool c = Condition();
-  ASSERT_DEATH((c ? Func1(0) : object2.Method("test")),
-               "(Func1|Method) failed");
-}
-
-// Death assertions can be used any where in a function.  In
-// particular, they can be inside a loop.
-TEST(MyDeathTest, InsideLoop) {
-  // Verifies that Foo(0), Foo(1), ..., and Foo(4) all die.
-  for (int i = 0; i < 5; i++) {
-    EXPECT_DEATH_M(Foo(i), "Foo has \\d+ errors",
-                   ::testing::Message() << "where i is " << i);
-  }
-}
-
-// A death assertion can contain a compound statement.
-TEST(MyDeathTest, CompoundStatement) {
-  // Verifies that at lease one of Bar(0), Bar(1), ..., and
-  // Bar(4) dies.
-  ASSERT_DEATH({
-    for (int i = 0; i < 5; i++) {
-      Bar(i);
-    }
-  },
-  "Bar has \\d+ errors");
-}
-```
-
-gtest-death-test_test.cc contains more examples if you are interested.
-
-## I have a fixture class `FooTest`, but `TEST_F(FooTest, Bar)` gives me error ``"no matching function for call to `FooTest::FooTest()'"``. Why?
-
-Googletest needs to be able to create objects of your test fixture class, so it
-must have a default constructor. Normally the compiler will define one for you.
-However, there are cases where you have to define your own:
-
-*   If you explicitly declare a non-default constructor for class `FooTest`
-    (`DISALLOW_EVIL_CONSTRUCTORS()` does this), then you need to define a
-    default constructor, even if it would be empty.
-*   If `FooTest` has a const non-static data member, then you have to define the
-    default constructor *and* initialize the const member in the initializer
-    list of the constructor. (Early versions of `gcc` doesn't force you to
-    initialize the const member. It's a bug that has been fixed in `gcc 4`.)
-
-## Why does ASSERT_DEATH complain about previous threads that were already joined?
-
-With the Linux pthread library, there is no turning back once you cross the line
-from single thread to multiple threads. The first time you create a thread, a
-manager thread is created in addition, so you get 3, not 2, threads. Later when
-the thread you create joins the main thread, the thread count decrements by 1,
-but the manager thread will never be killed, so you still have 2 threads, which
-means you cannot safely run a death test.
-
-The new NPTL thread library doesn't suffer from this problem, as it doesn't
-create a manager thread. However, if you don't control which machine your test
-runs on, you shouldn't depend on this.
-
-## Why does googletest require the entire test case, instead of individual tests, to be named *DeathTest when it uses ASSERT_DEATH?
-
-googletest does not interleave tests from different test cases. That is, it runs
-all tests in one test case first, and then runs all tests in the next test case,
-and so on. googletest does this because it needs to set up a test case before
-the first test in it is run, and tear it down afterwords. Splitting up the test
-case would require multiple set-up and tear-down processes, which is inefficient
-and makes the semantics unclean.
-
-If we were to determine the order of tests based on test name instead of test
-case name, then we would have a problem with the following situation:
-
-```c++
-TEST_F(FooTest, AbcDeathTest) { ... }
-TEST_F(FooTest, Uvw) { ... }
-
-TEST_F(BarTest, DefDeathTest) { ... }
-TEST_F(BarTest, Xyz) { ... }
-```
-
-Since `FooTest.AbcDeathTest` needs to run before `BarTest.Xyz`, and we don't
-interleave tests from different test cases, we need to run all tests in the
-`FooTest` case before running any test in the `BarTest` case. This contradicts
-with the requirement to run `BarTest.DefDeathTest` before `FooTest.Uvw`.
-
-## But I don't like calling my entire test case \*DeathTest when it contains both death tests and non-death tests. What do I do?
-
-You don't have to, but if you like, you may split up the test case into
-`FooTest` and `FooDeathTest`, where the names make it clear that they are
-related:
-
-```c++
-class FooTest : public ::testing::Test { ... };
-
-TEST_F(FooTest, Abc) { ... }
-TEST_F(FooTest, Def) { ... }
-
-using FooDeathTest = FooTest;
-
-TEST_F(FooDeathTest, Uvw) { ... EXPECT_DEATH(...) ... }
-TEST_F(FooDeathTest, Xyz) { ... ASSERT_DEATH(...) ... }
-```
-
-## googletest prints the LOG messages in a death test's child process only when the test fails. How can I see the LOG messages when the death test succeeds?
-
-Printing the LOG messages generated by the statement inside `EXPECT_DEATH()`
-makes it harder to search for real problems in the parent's log. Therefore,
-googletest only prints them when the death test has failed.
-
-If you really need to see such LOG messages, a workaround is to temporarily
-break the death test (e.g. by changing the regex pattern it is expected to
-match). Admittedly, this is a hack. We'll consider a more permanent solution
-after the fork-and-exec-style death tests are implemented.
-
-## The compiler complains about "no match for 'operator<<'" when I use an assertion. What gives?
-
-If you use a user-defined type `FooType` in an assertion, you must make sure
-there is an `std::ostream& operator<<(std::ostream&, const FooType&)` function
-defined such that we can print a value of `FooType`.
-
-In addition, if `FooType` is declared in a name space, the `<<` operator also
-needs to be defined in the *same* name space. See go/totw/49 for details.
-
-## How do I suppress the memory leak messages on Windows?
-
-Since the statically initialized googletest singleton requires allocations on
-the heap, the Visual C++ memory leak detector will report memory leaks at the
-end of the program run. The easiest way to avoid this is to use the
-`_CrtMemCheckpoint` and `_CrtMemDumpAllObjectsSince` calls to not report any
-statically initialized heap objects. See MSDN for more details and additional
-heap check/debug routines.
-
-
-## How can my code detect if it is running in a test?
-
-If you write code that sniffs whether it's running in a test and does different
-things accordingly, you are leaking test-only logic into production code and
-there is no easy way to ensure that the test-only code paths aren't run by
-mistake in production. Such cleverness also leads to
-[Heisenbugs](https://en.wikipedia.org/wiki/Heisenbug). Therefore we strongly
-advise against the practice, and googletest doesn't provide a way to do it.
-
-In general, the recommended way to cause the code to behave differently under
-test is [Dependency Injection](https://en.wikipedia.org/wiki/Dependency_injection). You can inject
-different functionality from the test and from the production code. Since your
-production code doesn't link in the for-test logic at all (the
-[`testonly`](https://docs.bazel.build/versions/master/be/common-definitions.html#common.testonly)
-attribute for BUILD targets helps to ensure that), there is no danger in
-accidentally running it.
-
-However, if you *really*, *really*, *really* have no choice, and if you follow
-the rule of ending your test program names with `_test`, you can use the
-*horrible* hack of sniffing your executable name (`argv[0]` in `main()`) to know
-whether the code is under test.
-
-
-## How do I temporarily disable a test?
-
-If you have a broken test that you cannot fix right away, you can add the
-DISABLED_ prefix to its name. This will exclude it from execution. This is
-better than commenting out the code or using #if 0, as disabled tests are still
-compiled (and thus won't rot).
-
-To include disabled tests in test execution, just invoke the test program with
-the --gtest_also_run_disabled_tests flag.
-
-## Is it OK if I have two separate `TEST(Foo, Bar)` test methods defined in different namespaces?
-
-Yes.
-
-The rule is **all test methods in the same test case must use the same fixture
-class.** This means that the following is **allowed** because both tests use the
-same fixture class (`::testing::Test`).
-
-```c++
-namespace foo {
-TEST(CoolTest, DoSomething) {
-  SUCCEED();
-}
-}  // namespace foo
-
-namespace bar {
-TEST(CoolTest, DoSomething) {
-  SUCCEED();
-}
-}  // namespace bar
-```
-
-However, the following code is **not allowed** and will produce a runtime error
-from googletest because the test methods are using different test fixture
-classes with the same test case name.
-
-```c++
-namespace foo {
-class CoolTest : public ::testing::Test {};  // Fixture foo::CoolTest
-TEST_F(CoolTest, DoSomething) {
-  SUCCEED();
-}
-}  // namespace foo
-
-namespace bar {
-class CoolTest : public ::testing::Test {};  // Fixture: bar::CoolTest
-TEST_F(CoolTest, DoSomething) {
-  SUCCEED();
-}
-}  // namespace bar
-```

-# Googletest Primer
-
-
-## Introduction: Why googletest?
-
-*googletest* helps you write better C++ tests.
-
-googletest is a testing framework developed by the Testing
-Technology team with Google's specific
-requirements and constraints in mind. No matter whether you work on Linux,
-Windows, or a Mac, if you write C++ code, googletest can help you. And it
-supports *any* kind of tests, not just unit tests.
-
-So what makes a good test, and how does googletest fit in? We believe:
-
-1.  Tests should be *independent* and *repeatable*. It's a pain to debug a test
-    that succeeds or fails as a result of other tests. googletest isolates the
-    tests by running each of them on a different object. When a test fails,
-    googletest allows you to run it in isolation for quick debugging.
-1.  Tests should be well *organized* and reflect the structure of the tested
-    code. googletest groups related tests into test cases that can share data
-    and subroutines. This common pattern is easy to recognize and makes tests
-    easy to maintain. Such consistency is especially helpful when people switch
-    projects and start to work on a new code base.
-1.  Tests should be *portable* and *reusable*. Google has a lot of code that is
-    platform-neutral, its tests should also be platform-neutral. googletest
-    works on different OSes, with different compilers (gcc, icc, and MSVC), with
-    or without exceptions, so googletest tests can easily work with a variety of
-    configurations.
-1.  When tests fail, they should provide as much *information* about the problem
-    as possible. googletest doesn't stop at the first test failure. Instead, it
-    only stops the current test and continues with the next. You can also set up
-    tests that report non-fatal failures after which the current test continues.
-    Thus, you can detect and fix multiple bugs in a single run-edit-compile
-    cycle.
-1.  The testing framework should liberate test writers from housekeeping chores
-    and let them focus on the test *content*. googletest automatically keeps
-    track of all tests defined, and doesn't require the user to enumerate them
-    in order to run them.
-1.  Tests should be *fast*. With googletest, you can reuse shared resources
-    across tests and pay for the set-up/tear-down only once, without making
-    tests depend on each other.
-
-Since googletest is based on the popular xUnit architecture, you'll feel right
-at home if you've used JUnit or PyUnit before. If not, it will take you about 10
-minutes to learn the basics and get started. So let's go!
-
-## Beware of the nomenclature
-
-_Note:_ There might be some confusion of idea due to different
-definitions of the terms _Test_, _Test Case_ and _Test Suite_, so beware
-of misunderstanding these.
-
-Historically, googletest started to use the term _Test Case_ for grouping
-related tests, whereas current publications including the International Software
-Testing Qualifications Board ([ISTQB](http://www.istqb.org/)) and various
-textbooks on Software Quality use the term _[Test
-Suite](http://glossary.istqb.org/search/test%20suite)_ for this.
-
-The related term _Test_, as it is used in the googletest, is corresponding to
-the term _[Test Case](http://glossary.istqb.org/search/test%20case)_ of ISTQB
-and others.
-
-The term _Test_ is commonly of broad enough sense, including ISTQB's
-definition of _Test Case_, so it's not much of a problem here. But the
-term _Test Case_ as used in Google Test is of contradictory sense and thus confusing.
-
-Unfortunately replacing the term _Test Case_ by _Test Suite_ throughout the
-googletest is not easy without breaking dependent projects, as `TestCase` is
-part of the public API at various places.
-
-So for the time being, please be aware of the different definitions of
-the terms:
-
-Meaning                                                                              | googletest Term                                                                                            | [ISTQB](http://www.istqb.org/) Term

-
-## Basic Concepts
-
-When using googletest, you start by writing *assertions*, which are statements
-that check whether a condition is true. An assertion's result can be *success*,
-*nonfatal failure*, or *fatal failure*. If a fatal failure occurs, it aborts the
-current function; otherwise the program continues normally.
-
-*Tests* use assertions to verify the tested code's behavior. If a test crashes
-or has a failed assertion, then it *fails*; otherwise it *succeeds*.
-
-A *test case* contains one or many tests. You should group your tests into test
-cases that reflect the structure of the tested code. When multiple tests in a
-test case need to share common objects and subroutines, you can put them into a
-*test fixture* class.
-
-A *test program* can contain multiple test cases.
-
-We'll now explain how to write a test program, starting at the individual
-assertion level and building up to tests and test cases.
-
-## Assertions
-
-googletest assertions are macros that resemble function calls. You test a class
-or function by making assertions about its behavior. When an assertion fails,
-googletest prints the assertion's source file and line number location, along
-with a failure message. You may also supply a custom failure message which will
-be appended to googletest's message.
-
-The assertions come in pairs that test the same thing but have different effects
-on the current function. `ASSERT_*` versions generate fatal failures when they
-fail, and **abort the current function**. `EXPECT_*` versions generate nonfatal
-failures, which don't abort the current function. Usually `EXPECT_*` are
-preferred, as they allow more than one failure to be reported in a test.
-However, you should use `ASSERT_*` if it doesn't make sense to continue when the
-assertion in question fails.
-
-Since a failed `ASSERT_*` returns from the current function immediately,
-possibly skipping clean-up code that comes after it, it may cause a space leak.
-Depending on the nature of the leak, it may or may not be worth fixing - so keep
-this in mind if you get a heap checker error in addition to assertion errors.
-
-To provide a custom failure message, simply stream it into the macro using the
-`<<` operator, or a sequence of such operators. An example:
-
-```c++
-ASSERT_EQ(x.size(), y.size()) << "Vectors x and y are of unequal length";
-
-for (int i = 0; i < x.size(); ++i) {
-  EXPECT_EQ(x[i], y[i]) << "Vectors x and y differ at index " << i;
-}
-```
-
-Anything that can be streamed to an `ostream` can be streamed to an assertion
-macro--in particular, C strings and `string` objects. If a wide string
-(`wchar_t*`, `TCHAR*` in `UNICODE` mode on Windows, or `std::wstring`) is
-streamed to an assertion, it will be translated to UTF-8 when printed.
-
-### Basic Assertions
-
-These assertions do basic true/false condition testing.
-
-Fatal assertion            | Nonfatal assertion         | Verifies
--------------------------- | -------------------------- | --------------------
-`ASSERT_TRUE(condition);`  | `EXPECT_TRUE(condition);`  | `condition` is true
-`ASSERT_FALSE(condition);` | `EXPECT_FALSE(condition);` | `condition` is false
-
-Remember, when they fail, `ASSERT_*` yields a fatal failure and returns from the
-current function, while `EXPECT_*` yields a nonfatal failure, allowing the
-function to continue running. In either case, an assertion failure means its
-containing test fails.
-
-**Availability**: Linux, Windows, Mac.
-
-### Binary Comparison
-
-This section describes assertions that compare two values.
-
-Fatal assertion          | Nonfatal assertion       | Verifies
------------------------- | ------------------------ | --------------
-`ASSERT_EQ(val1, val2);` | `EXPECT_EQ(val1, val2);` | `val1 == val2`
-`ASSERT_NE(val1, val2);` | `EXPECT_NE(val1, val2);` | `val1 != val2`
-`ASSERT_LT(val1, val2);` | `EXPECT_LT(val1, val2);` | `val1 < val2`
-`ASSERT_LE(val1, val2);` | `EXPECT_LE(val1, val2);` | `val1 <= val2`
-`ASSERT_GT(val1, val2);` | `EXPECT_GT(val1, val2);` | `val1 > val2`
-`ASSERT_GE(val1, val2);` | `EXPECT_GE(val1, val2);` | `val1 >= val2`
-
-Value arguments must be comparable by the assertion's comparison operator or
-you'll get a compiler error. We used to require the arguments to support the
-`<<` operator for streaming to an `ostream`, but it's no longer necessary. If
-`<<` is supported, it will be called to print the arguments when the assertion
-fails; otherwise googletest will attempt to print them in the best way it can.
-For more details and how to customize the printing of the arguments, see
-gMock [recipe](../../googlemock/docs/CookBook.md#teaching-google-mock-how-to-print-your-values).).
-
-These assertions can work with a user-defined type, but only if you define the
-corresponding comparison operator (e.g. `==`, `<`, etc). Since this is
-discouraged by the Google [C++ Style
-Guide](https://google.github.io/styleguide/cppguide.html#Operator_Overloading),
-you may need to use `ASSERT_TRUE()` or `EXPECT_TRUE()` to assert the equality of
-two objects of a user-defined type.
-
-However, when possible, `ASSERT_EQ(actual, expected)` is preferred to
-`ASSERT_TRUE(actual == expected)`, since it tells you `actual` and `expected`'s
-values on failure.
-
-Arguments are always evaluated exactly once. Therefore, it's OK for the
-arguments to have side effects. However, as with any ordinary C/C++ function,
-the arguments' evaluation order is undefined (i.e. the compiler is free to
-choose any order) and your code should not depend on any particular argument
-evaluation order.
-
-`ASSERT_EQ()` does pointer equality on pointers. If used on two C strings, it
-tests if they are in the same memory location, not if they have the same value.
-Therefore, if you want to compare C strings (e.g. `const char*`) by value, use
-`ASSERT_STREQ()`, which will be described later on. In particular, to assert
-that a C string is `NULL`, use `ASSERT_STREQ(c_string, NULL)`. Consider use
-`ASSERT_EQ(c_string, nullptr)` if c++11 is supported. To compare two `string`
-objects, you should use `ASSERT_EQ`.
-
-When doing pointer comparisons use `*_EQ(ptr, nullptr)` and `*_NE(ptr, nullptr)`
-instead of `*_EQ(ptr, NULL)` and `*_NE(ptr, NULL)`. This is because `nullptr` is
-typed while `NULL` is not. See [FAQ](faq.md#why-does-google-test-support-expect_eqnull-ptr-and-assert_eqnull-ptr-but-not-expect_nenull-ptr-and-assert_nenull-ptr)
-for more details.
-
-If you're working with floating point numbers, you may want to use the floating
-point variations of some of these macros in order to avoid problems caused by
-rounding. See [Advanced googletest Topics](advanced.md) for details.
-
-Macros in this section work with both narrow and wide string objects (`string`
-and `wstring`).
-
-**Availability**: Linux, Windows, Mac.
-
-**Historical note**: Before February 2016 `*_EQ` had a convention of calling it
-as `ASSERT_EQ(expected, actual)`, so lots of existing code uses this order. Now
-`*_EQ` treats both parameters in the same way.
-
-### String Comparison
-
-The assertions in this group compare two **C strings**. If you want to compare
-two `string` objects, use `EXPECT_EQ`, `EXPECT_NE`, and etc instead.
-
-| Fatal assertion                 | Nonfatal assertion              | Verifies                                                 |
-| ------------------------------- | ------------------------------- | -------------------------------------------------------- |
-| `ASSERT_STREQ(str1, str2);`     | `EXPECT_STREQ(str1, str2);`     | the two C strings have the same content                  |
-| `ASSERT_STRNE(str1, str2);`     | `EXPECT_STRNE(str1, str2);`     | the two C strings have different contents                |
-| `ASSERT_STRCASEEQ(str1, str2);` | `EXPECT_STRCASEEQ(str1, str2);` | the two C strings have the same content, ignoring case   |
-| `ASSERT_STRCASENE(str1, str2);` | `EXPECT_STRCASENE(str1, str2);` | the two C strings have different contents, ignoring case |
-
-Note that "CASE" in an assertion name means that case is ignored. A `NULL`
-pointer and an empty string are considered *different*.
-
-`*STREQ*` and `*STRNE*` also accept wide C strings (`wchar_t*`). If a comparison
-of two wide strings fails, their values will be printed as UTF-8 narrow strings.
-
-**Availability**: Linux, Windows, Mac.
-
-**See also**: For more string comparison tricks (substring, prefix, suffix, and
-regular expression matching, for example), see
-[this](https://github.com/google/googletest/blob/master/googletest/docs/advanced.md)
-in the Advanced googletest Guide.

-## Simple Tests
-
-To create a test:
-
-1.  Use the `TEST()` macro to define and name a test function, These are
-    ordinary C++ functions that don't return a value.
-1.  In this function, along with any valid C++ statements you want to include,
-    use the various googletest assertions to check values.
-1.  The test's result is determined by the assertions; if any assertion in the
-    test fails (either fatally or non-fatally), or if the test crashes, the
-    entire test fails. Otherwise, it succeeds.
-
-```c++
-TEST(TestCaseName, TestName) {
-  ... test body ...
-}
-```
-
-`TEST()` arguments go from general to specific. The *first* argument is the name
-of the test case, and the *second* argument is the test's name within the test
-case. Both names must be valid C++ identifiers, and they should not contain
-underscore (`_`). A test's *full name* consists of its containing test case and
-its individual name. Tests from different test cases can have the same
-individual name.
-
-For example, let's take a simple integer function:
-
-```c++
-int Factorial(int n);  // Returns the factorial of n
-```
-
-A test case for this function might look like:
-
-```c++
-// Tests factorial of 0.
-TEST(FactorialTest, HandlesZeroInput) {
-  EXPECT_EQ(Factorial(0), 1);
-}
-
-// Tests factorial of positive numbers.
-TEST(FactorialTest, HandlesPositiveInput) {
-  EXPECT_EQ(Factorial(1), 1);
-  EXPECT_EQ(Factorial(2), 2);
-  EXPECT_EQ(Factorial(3), 6);
-  EXPECT_EQ(Factorial(8), 40320);
-}
-```
-
-googletest groups the test results by test cases, so logically-related tests
-should be in the same test case; in other words, the first argument to their
-`TEST()` should be the same. In the above example, we have two tests,
-`HandlesZeroInput` and `HandlesPositiveInput`, that belong to the same test case
-`FactorialTest`.
-
-When naming your test cases and tests, you should follow the same convention as
-for [naming functions and
-classes](https://google.github.io/styleguide/cppguide.html#Function_Names).

-
-## Test Fixtures: Using the Same Data Configuration for Multiple Tests
-
-If you find yourself writing two or more tests that operate on similar data, you
-can use a *test fixture*. It allows you to reuse the same configuration of
-objects for several different tests.
-
-To create a fixture:
-
-1.  Derive a class from `::testing::Test` . Start its body with `protected:` as
-    we'll want to access fixture members from sub-classes.
-1.  Inside the class, declare any objects you plan to use.
-1.  If necessary, write a default constructor or `SetUp()` function to prepare
-    the objects for each test. A common mistake is to spell `SetUp()` as
-    **`Setup()`** with a small `u` - Use `override` in C++11 to make sure you
-    spelled it correctly
-1.  If necessary, write a destructor or `TearDown()` function to release any
-    resources you allocated in `SetUp()` . To learn when you should use the
-    constructor/destructor and when you should use `SetUp()/TearDown()`, read
-    this [FAQ](faq.md#should-i-use-the-constructordestructor-of-the-test-fixture-or-setupteardown) entry.
-1.  If needed, define subroutines for your tests to share.
-
-When using a fixture, use `TEST_F()` instead of `TEST()` as it allows you to
-access objects and subroutines in the test fixture:
-
-```c++
-TEST_F(TestCaseName, TestName) {
-  ... test body ...
-}
-```
-
-Like `TEST()`, the first argument is the test case name, but for `TEST_F()` this
-must be the name of the test fixture class. You've probably guessed: `_F` is for
-fixture.
-
-Unfortunately, the C++ macro system does not allow us to create a single macro
-that can handle both types of tests. Using the wrong macro causes a compiler
-error.
-
-Also, you must first define a test fixture class before using it in a
-`TEST_F()`, or you'll get the compiler error "`virtual outside class
-declaration`".
-
-For each test defined with `TEST_F()` , googletest will create a *fresh* test
-fixture at runtime, immediately initialize it via `SetUp()` , run the test,
-clean up by calling `TearDown()` , and then delete the test fixture. Note that
-different tests in the same test case have different test fixture objects, and
-googletest always deletes a test fixture before it creates the next one.
-googletest does **not** reuse the same test fixture for multiple tests. Any
-changes one test makes to the fixture do not affect other tests.
-
-As an example, let's write tests for a FIFO queue class named `Queue`, which has
-the following interface:
-
-```c++
-template <typename E>  // E is the element type.
-class Queue {
- public:
-  Queue();
-  void Enqueue(const E& element);
-  E* Dequeue();  // Returns NULL if the queue is empty.
-  size_t size() const;
-  ...
-};
-```
-
-First, define a fixture class. By convention, you should give it the name
-`FooTest` where `Foo` is the class being tested.
-
-```c++
-class QueueTest : public ::testing::Test {
- protected:
-  void SetUp() override {
-     q1_.Enqueue(1);
-     q2_.Enqueue(2);
-     q2_.Enqueue(3);
-  }
-
-  // void TearDown() override {}
-
-  Queue<int> q0_;
-  Queue<int> q1_;
-  Queue<int> q2_;
-};
-```
-
-In this case, `TearDown()` is not needed since we don't have to clean up after
-each test, other than what's already done by the destructor.
-
-Now we'll write tests using `TEST_F()` and this fixture.
-
-```c++
-TEST_F(QueueTest, IsEmptyInitially) {
-  EXPECT_EQ(q0_.size(), 0);
-}
-
-TEST_F(QueueTest, DequeueWorks) {
-  int* n = q0_.Dequeue();
-  EXPECT_EQ(n, nullptr);
-
-  n = q1_.Dequeue();
-  ASSERT_NE(n, nullptr);
-  EXPECT_EQ(*n, 1);
-  EXPECT_EQ(q1_.size(), 0);
-  delete n;
-
-  n = q2_.Dequeue();
-  ASSERT_NE(n, nullptr);
-  EXPECT_EQ(*n, 2);
-  EXPECT_EQ(q2_.size(), 1);
-  delete n;
-}
-```
-
-The above uses both `ASSERT_*` and `EXPECT_*` assertions. The rule of thumb is
-to use `EXPECT_*` when you want the test to continue to reveal more errors after
-the assertion failure, and use `ASSERT_*` when continuing after failure doesn't
-make sense. For example, the second assertion in the `Dequeue` test is
-=ASSERT_NE(nullptr, n)=, as we need to dereference the pointer `n` later, which
-would lead to a segfault when `n` is `NULL`.
-
-When these tests run, the following happens:
-
-1.  googletest constructs a `QueueTest` object (let's call it `t1` ).
-1.  `t1.SetUp()` initializes `t1` .
-1.  The first test ( `IsEmptyInitially` ) runs on `t1` .
-1.  `t1.TearDown()` cleans up after the test finishes.
-1.  `t1` is destructed.
-1.  The above steps are repeated on another `QueueTest` object, this time
-    running the `DequeueWorks` test.
-
-**Availability**: Linux, Windows, Mac.
-
-
-## Invoking the Tests
-
-`TEST()` and `TEST_F()` implicitly register their tests with googletest. So,
-unlike with many other C++ testing frameworks, you don't have to re-list all
-your defined tests in order to run them.
-
-After defining your tests, you can run them with `RUN_ALL_TESTS()` , which
-returns `0` if all the tests are successful, or `1` otherwise. Note that
-`RUN_ALL_TESTS()` runs *all tests* in your link unit -- they can be from
-different test cases, or even different source files.
-
-When invoked, the `RUN_ALL_TESTS()` macro:
-
-1. Saves the state of all googletest flags
-
-*   Creates a test fixture object for the first test.
-
-*   Initializes it via `SetUp()`.
-
-*   Runs the test on the fixture object.
-
-*   Cleans up the fixture via `TearDown()`.
-
-*   Deletes the fixture.
-
-* Restores the state of all googletest flags
-
-*   Repeats the above steps for the next test, until all tests have run.
-
-If a fatal failure happens the subsequent steps will be skipped.
-
-> IMPORTANT: You must **not** ignore the return value of `RUN_ALL_TESTS()`, or
-> you will get a compiler error. The rationale for this design is that the
-> automated testing service determines whether a test has passed based on its
-> exit code, not on its stdout/stderr output; thus your `main()` function must
-> return the value of `RUN_ALL_TESTS()`.
->
-> Also, you should call `RUN_ALL_TESTS()` only **once**. Calling it more than
-> once conflicts with some advanced googletest features (e.g. thread-safe [death
-> tests](advanced#death-tests)) and thus is not supported.
-
-**Availability**: Linux, Windows, Mac.
-
-## Writing the main() Function
-
-In `google3`, the simplest approach is to use the default main() function
-provided by linking in `"//testing/base/public:gtest_main"`. If that doesn't
-cover what you need, you should write your own main() function, which should
-return the value of `RUN_ALL_TESTS()`. Link to `"//testing/base/public:gunit"`.
-You can start from this boilerplate:
-
-```c++
-#include "this/package/foo.h"
-#include "gtest/gtest.h"
-
-namespace {
-
-// The fixture for testing class Foo.
-class FooTest : public ::testing::Test {
- protected:
-  // You can remove any or all of the following functions if its body
-  // is empty.
-
-  FooTest() {
-     // You can do set-up work for each test here.
-  }
-
-  ~FooTest() override {
-     // You can do clean-up work that doesn't throw exceptions here.
-  }
-
-  // If the constructor and destructor are not enough for setting up
-  // and cleaning up each test, you can define the following methods:
-
-  void SetUp() override {
-     // Code here will be called immediately after the constructor (right
-     // before each test).
-  }
-
-  void TearDown() override {
-     // Code here will be called immediately after each test (right
-     // before the destructor).
-  }
-
-  // Objects declared here can be used by all tests in the test case for Foo.
-};
-
-// Tests that the Foo::Bar() method does Abc.
-TEST_F(FooTest, MethodBarDoesAbc) {
-  const std::string input_filepath = "this/package/testdata/myinputfile.dat";
-  const std::string output_filepath = "this/package/testdata/myoutputfile.dat";
-  Foo f;
-  EXPECT_EQ(f.Bar(input_filepath, output_filepath), 0);
-}
-
-// Tests that Foo does Xyz.
-TEST_F(FooTest, DoesXyz) {
-  // Exercises the Xyz feature of Foo.
-}
-
-}  // namespace
-
-int main(int argc, char **argv) {
-  ::testing::InitGoogleTest(&argc, argv);
-  return RUN_ALL_TESTS();
-}
-```
-
-
-The `::testing::InitGoogleTest()` function parses the command line for
-googletest flags, and removes all recognized flags. This allows the user to
-control a test program's behavior via various flags, which we'll cover in
-[AdvancedGuide](advanced.md). You **must** call this function before calling
-`RUN_ALL_TESTS()`, or the flags won't be properly initialized.
-
-On Windows, `InitGoogleTest()` also works with wide strings, so it can be used
-in programs compiled in `UNICODE` mode as well.
-
-But maybe you think that writing all those main() functions is too much work? We
-agree with you completely and that's why Google Test provides a basic
-implementation of main(). If it fits your needs, then just link your test with
-gtest\_main library and you are good to go.
-
-NOTE: `ParseGUnitFlags()` is deprecated in favor of `InitGoogleTest()`.
-
-
-## Known Limitations
-
-*   Google Test is designed to be thread-safe. The implementation is thread-safe
-    on systems where the `pthreads` library is available. It is currently
-    _unsafe_ to use Google Test assertions from two threads concurrently on
-    other systems (e.g. Windows). In most tests this is not an issue as usually
-    the assertions are done in the main thread. If you want to help, you can
-    volunteer to implement the necessary synchronization primitives in
-    `gtest-port.h` for your platform.

-// Here's what happens when an ASSERT_DEATH* or EXPECT_DEATH* is

-//
-//   1. It generates a warning if there is more than one active
-//   thread.  This is because it's safe to fork() or clone() only
-//   when there is a single thread.
-//
-//   2. The parent process clone()s a sub-process and runs the death
-//   test in it; the sub-process exits with code 0 at the end of the
-//   death test, if it hasn't exited already.
-//
-//   3. The parent process waits for the sub-process to terminate.
-//
-//   4. The parent process checks the exit code and error message of
-//   the sub-process.
-//
-// Examples:
-//
-//   ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");
-//   for (int i = 0; i < 5; i++) {
-//     EXPECT_DEATH(server.ProcessRequest(i),
-//                  "Invalid request .* in ProcessRequest()")
-//                  << "Failed to die on request " << i;
-//   }
-//
-//   ASSERT_EXIT(server.ExitNow(), ::testing::ExitedWithCode(0), "Exiting");
-//
-//   bool KilledBySIGHUP(int exit_code) {
-//     return WIFSIGNALED(exit_code) && WTERMSIG(exit_code) == SIGHUP;
-//   }
-//
-//   ASSERT_EXIT(client.HangUpServer(), KilledBySIGHUP, "Hanging up!");
-//
-// On the regular expressions used in death tests:
-//
-//   GOOGLETEST_CM0005 DO NOT DELETE
-//   On POSIX-compliant systems (*nix), we use the <regex.h> library,
-//   which uses the POSIX extended regex syntax.
-//
-//   On other platforms (e.g. Windows or Mac), we only support a simple regex
-//   syntax implemented as part of Google Test.  This limited
-//   implementation should be enough most of the time when writing
-//   death tests; though it lacks many features you can find in PCRE
-//   or POSIX extended regex syntax.  For example, we don't support
-//   union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and
-//   repetition count ("x{5,7}"), among others.
-//
-//   Below is the syntax that we do support.  We chose it to be a
-//   subset of both PCRE and POSIX extended regex, so it's easy to
-//   learn wherever you come from.  In the following: 'A' denotes a
-//   literal character, period (.), or a single \\ escape sequence;
-//   'x' and 'y' denote regular expressions; 'm' and 'n' are for
-//   natural numbers.
-//
-//     c     matches any literal character c
-//     \\d   matches any decimal digit
-//     \\D   matches any character that's not a decimal digit
-//     \\f   matches \f
-//     \\n   matches \n
-//     \\r   matches \r
-//     \\s   matches any ASCII whitespace, including \n
-//     \\S   matches any character that's not a whitespace
-//     \\t   matches \t
-//     \\v   matches \v
-//     \\w   matches any letter, _, or decimal digit
-//     \\W   matches any character that \\w doesn't match
-//     \\c   matches any literal character c, which must be a punctuation
-//     .     matches any single character except \n
-//     A?    matches 0 or 1 occurrences of A
-//     A*    matches 0 or many occurrences of A
-//     A+    matches 1 or many occurrences of A
-//     ^     matches the beginning of a string (not that of each line)
-//     $     matches the end of a string (not that of each line)
-//     xy    matches x followed by y
-//
-//   If you accidentally use PCRE or POSIX extended regex features
-//   not implemented by us, you will get a run-time failure.  In that
-//   case, please try to rewrite your regular expression within the
-//   above syntax.
-//
-//   This implementation is *not* meant to be as highly tuned or robust
-//   as a compiled regex library, but should perform well enough for a
-//   death test, which already incurs significant overhead by launching
-//   a child process.
-//
-// Known caveats:
-//
-//   A "threadsafe" style death test obtains the path to the test
-//   program from argv[0] and re-executes it in the sub-process.  For
-//   simplicity, the current implementation doesn't search the PATH
-//   when launching the sub-process.  This means that the user must
-//   invoke the test program via a path that contains at least one
-//   path separator (e.g. path/to/foo_test and
-//   /absolute/path/to/bar_test are fine, but foo_test is not).  This
-//   is rarely a problem as people usually don't put the test binary
-//   directory in PATH.

-
-// This macro is used for implementing macros such as
-// EXPECT_DEATH_IF_SUPPORTED and ASSERT_DEATH_IF_SUPPORTED on systems where
-// death tests are not supported. Those macros must compile on such systems
-// iff EXPECT_DEATH and ASSERT_DEATH compile with the same parameters on
-// systems that support death tests. This allows one to write such a macro
-// on a system that does not support death tests and be sure that it will
-// compile on a death-test supporting system. It is exposed publicly so that
-// systems that have death-tests with stricter requirements than
-// GTEST_HAS_DEATH_TEST can write their own equivalent of
-// EXPECT_DEATH_IF_SUPPORTED and ASSERT_DEATH_IF_SUPPORTED.
-//
-// Parameters:
-//   statement -  A statement that a macro such as EXPECT_DEATH would test
-//                for program termination. This macro has to make sure this
-//                statement is compiled but not executed, to ensure that
-//                EXPECT_DEATH_IF_SUPPORTED compiles with a certain
-//                parameter iff EXPECT_DEATH compiles with it.
-//   regex     -  A regex that a macro such as EXPECT_DEATH would use to test
-//                the output of statement.  This parameter has to be
-//                compiled but not evaluated by this macro, to ensure that
-//                this macro only accepts expressions that a macro such as
-//                EXPECT_DEATH would accept.
-//   terminator - Must be an empty statement for EXPECT_DEATH_IF_SUPPORTED
-//                and a return statement for ASSERT_DEATH_IF_SUPPORTED.
-//                This ensures that ASSERT_DEATH_IF_SUPPORTED will not
-//                compile inside functions where ASSERT_DEATH doesn't
-//                compile.
-//
-//  The branch that has an always false condition is used to ensure that
-//  statement and regex are compiled (and thus syntactically correct) but
-//  never executed. The unreachable code macro protects the terminator
-//  statement from generating an 'unreachable code' warning in case
-//  statement unconditionally returns or throws. The Message constructor at
-//  the end allows the syntax of streaming additional messages into the
-//  macro, for compilational compatibility with EXPECT_DEATH/ASSERT_DEATH.

-//   2. Then you stream the Message object to an ostream.

-// Here is how you use value-parameterized tests:
-
-#if 0
-
-// To write value-parameterized tests, first you should define a fixture
-// class. It is usually derived from testing::TestWithParam<T> (see below for
-// another inheritance scheme that's sometimes useful in more complicated
-// class hierarchies), where the type of your parameter values.
-// TestWithParam<T> is itself derived from testing::Test. T can be any
-// copyable type. If it's a raw pointer, you are responsible for managing the
-// lifespan of the pointed values.
-
-class FooTest : public ::testing::TestWithParam<const char*> {
-  // You can implement all the usual class fixture members here.
-};
-
-// Then, use the TEST_P macro to define as many parameterized tests
-// for this fixture as you want. The _P suffix is for "parameterized"
-// or "pattern", whichever you prefer to think.
-
-TEST_P(FooTest, DoesBlah) {

-// Finally, you can use INSTANTIATE_TEST_CASE_P to instantiate the test
-// case with any set of parameters you want. Google Test defines a number
-// of functions for generating test parameters. They return what we call
-// (surprise!) parameter generators. Here is a summary of them, which
-// are all in the testing namespace:
-//
-//
-//  Range(begin, end [, step]) - Yields values {begin, begin+step,
-//                               begin+step+step, ...}. The values do not
-//                               include end. step defaults to 1.
-//  Values(v1, v2, ..., vN)    - Yields values {v1, v2, ..., vN}.
-//  ValuesIn(container)        - Yields values from a C-style array, an STL
-//  ValuesIn(begin,end)          container, or an iterator range [begin, end).
-//  Bool()                     - Yields sequence {false, true}.
-//  Combine(g1, g2, ..., gN)   - Yields all combinations (the Cartesian product
-//                               for the math savvy) of the values generated
-//                               by the N generators.
-//
-// For more details, see comments at the definitions of these functions below
-// in this file.
-//
-// The following statement will instantiate tests from the FooTest test case
-// each with parameter values "meeny", "miny", and "moe".
-
-INSTANTIATE_TEST_CASE_P(InstantiationName,
-                        FooTest,
-                        Values("meeny", "miny", "moe"));
-
-// To distinguish different instances of the pattern, (yes, you
-// can instantiate it more then once) the first argument to the
-// INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the
-// actual test case name. Remember to pick unique prefixes for different
-// instantiations. The tests from the instantiation above will have
-// these names:
-//
-//    * InstantiationName/FooTest.DoesBlah/0 for "meeny"
-//    * InstantiationName/FooTest.DoesBlah/1 for "miny"
-//    * InstantiationName/FooTest.DoesBlah/2 for "moe"
-//    * InstantiationName/FooTest.HasBlahBlah/0 for "meeny"
-//    * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
-//    * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
-//
-// You can use these names in --gtest_filter.
-//
-// This statement will instantiate all tests from FooTest again, each
-// with parameter values "cat" and "dog":
-
-const char* pets[] = {"cat", "dog"};
-INSTANTIATE_TEST_CASE_P(AnotherInstantiationName, FooTest, ValuesIn(pets));

-//    * AnotherInstantiationName/FooTest.DoesBlah/1 for "dog"
-//    * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
-//    * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
-//
-// Please note that INSTANTIATE_TEST_CASE_P will instantiate all tests
-// in the given test case, whether their definitions come before or
-// AFTER the INSTANTIATE_TEST_CASE_P statement.
-//
-// Please also note that generator expressions (including parameters to the
-// generators) are evaluated in InitGoogleTest(), after main() has started.
-// This allows the user on one hand, to adjust generator parameters in order
-// to dynamically determine a set of tests to run and on the other hand,
-// give the user a chance to inspect the generated tests with Google Test
-// reflection API before RUN_ALL_TESTS() is executed.
-//
-// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
-// for more examples.
-//
-// In the future, we plan to publish the API for defining new parameter
-// generators. But for now this interface remains part of the internal
-// implementation and is subject to change.
-//
-//
-// A parameterized test fixture must be derived from testing::Test and from
-// testing::WithParamInterface<T>, where T is the type of the parameter
-// values. Inheriting from TestWithParam<T> satisfies that requirement because
-// TestWithParam<T> inherits from both Test and WithParamInterface. In more
-// complicated hierarchies, however, it is occasionally useful to inherit
-// separately from Test and WithParamInterface. For example:
-
-class BaseTest : public ::testing::Test {
-  // You can inherit all the usual members for a non-parameterized test
-  // fixture here.
-};
-
-class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {

-

-//     * It must have operator<() defined.
-//     Elements in the resulting sequences will also have that type.

-// ValuesIn() function allows generation of tests with parameters coming from
-// a container.
-//
-// Synopsis:
-// ValuesIn(const T (&array)[N])
-//   - returns a generator producing sequences with elements from
-//     a C-style array.
-// ValuesIn(const Container& container)
-//   - returns a generator producing sequences with elements from
-//     an STL-style container.
-// ValuesIn(Iterator begin, Iterator end)
-//   - returns a generator producing sequences with elements from
-//     a range [begin, end) defined by a pair of STL-style iterators. These
-//     iterators can also be plain C pointers.
-//
-// Please note that ValuesIn copies the values from the containers
-// passed in and keeps them to generate tests in RUN_ALL_TESTS().
-//
-// Examples:
-//
-// This instantiates tests from test case StringTest
-// each with C-string values of "foo", "bar", and "baz":
-//
-// const char* strings[] = {"foo", "bar", "baz"};
-// INSTANTIATE_TEST_CASE_P(StringSequence, StringTest, ValuesIn(strings));
-//
-// This instantiates tests from test case StlStringTest
-// each with STL strings with values "a" and "b":
-//
-// ::std::vector< ::std::string> GetParameterStrings() {
-//   ::std::vector< ::std::string> v;
-//   v.push_back("a");
-//   v.push_back("b");
-//   return v;
-// }
-//
-// INSTANTIATE_TEST_CASE_P(CharSequence,
-//                         StlStringTest,
-//                         ValuesIn(GetParameterStrings()));
-//
-//
-// This will also instantiate tests from CharTest
-// each with parameter values 'a' and 'b':
-//
-// ::std::list<char> GetParameterChars() {
-//   ::std::list<char> list;
-//   list.push_back('a');
-//   list.push_back('b');
-//   return list;
-// }
-// ::std::list<char> l = GetParameterChars();
-// INSTANTIATE_TEST_CASE_P(CharSequence2,
-//                         CharTest,
-//                         ValuesIn(l.begin(), l.end()));

-// Test.
-//
-// Example:
-//
-// This will instantiate tests in test case AnimalTest each one with

-// class FlagDependentTest
-//     : public testing::TestWithParam<tuple<bool, bool> > {

-// Finally, you can use INSTANTIATE_TEST_CASE_P to instantiate the test
-// case with any set of parameters you want. Google Test defines a number
-// of functions for generating test parameters. They return what we call
-// (surprise!) parameter generators. Here is a summary of them, which
-// are all in the testing namespace:
-//
-//
-//  Range(begin, end [, step]) - Yields values {begin, begin+step,
-//                               begin+step+step, ...}. The values do not
-//                               include end. step defaults to 1.
-//  Values(v1, v2, ..., vN)    - Yields values {v1, v2, ..., vN}.
-//  ValuesIn(container)        - Yields values from a C-style array, an STL
-//  ValuesIn(begin,end)          container, or an iterator range [begin, end).
-//  Bool()                     - Yields sequence {false, true}.
-//  Combine(g1, g2, ..., gN)   - Yields all combinations (the Cartesian product
-//                               for the math savvy) of the values generated
-//                               by the N generators.
-//
-// For more details, see comments at the definitions of these functions below
-// in this file.
-//
-// The following statement will instantiate tests from the FooTest test case
-// each with parameter values "meeny", "miny", and "moe".
-
-INSTANTIATE_TEST_CASE_P(InstantiationName,
-                        FooTest,
-                        Values("meeny", "miny", "moe"));
-
-// To distinguish different instances of the pattern, (yes, you
-// can instantiate it more then once) the first argument to the
-// INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the
-// actual test case name. Remember to pick unique prefixes for different
-// instantiations. The tests from the instantiation above will have
-// these names:
-//
-//    * InstantiationName/FooTest.DoesBlah/0 for "meeny"
-//    * InstantiationName/FooTest.DoesBlah/1 for "miny"
-//    * InstantiationName/FooTest.DoesBlah/2 for "moe"
-//    * InstantiationName/FooTest.HasBlahBlah/0 for "meeny"
-//    * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
-//    * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
-//
-// You can use these names in --gtest_filter.
-//
-// This statement will instantiate all tests from FooTest again, each
-// with parameter values "cat" and "dog":
-
-const char* pets[] = {"cat", "dog"};
-INSTANTIATE_TEST_CASE_P(AnotherInstantiationName, FooTest, ValuesIn(pets));

-//    * AnotherInstantiationName/FooTest.DoesBlah/1 for "dog"
-//    * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
-//    * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
-//
-// Please note that INSTANTIATE_TEST_CASE_P will instantiate all tests
-// in the given test case, whether their definitions come before or
-// AFTER the INSTANTIATE_TEST_CASE_P statement.
-//
-// Please also note that generator expressions (including parameters to the
-// generators) are evaluated in InitGoogleTest(), after main() has started.
-// This allows the user on one hand, to adjust generator parameters in order
-// to dynamically determine a set of tests to run and on the other hand,
-// give the user a chance to inspect the generated tests with Google Test
-// reflection API before RUN_ALL_TESTS() is executed.
-//
-// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
-// for more examples.
-//
-// In the future, we plan to publish the API for defining new parameter
-// generators. But for now this interface remains part of the internal
-// implementation and is subject to change.
-//
-//
-// A parameterized test fixture must be derived from testing::Test and from
-// testing::WithParamInterface<T>, where T is the type of the parameter
-// values. Inheriting from TestWithParam<T> satisfies that requirement because
-// TestWithParam<T> inherits from both Test and WithParamInterface. In more
-// complicated hierarchies, however, it is occasionally useful to inherit
-// separately from Test and WithParamInterface. For example:
-
-class BaseTest : public ::testing::Test {
-  // You can inherit all the usual members for a non-parameterized test
-  // fixture here.
-};
-
-class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {
-  // The usual test fixture members go here too.
-};
-
-TEST_F(BaseTest, HasFoo) {
-  // This is an ordinary non-parameterized test.
-}
-
-TEST_P(DerivedTest, DoesBlah) {
-  // GetParam works just the same here as if you inherit from TestWithParam.
-  EXPECT_TRUE(foo.Blah(GetParam()));

-// This file implements a universal value printer that can print a
-// value of any type T:
-//
-//   void ::testing::internal::UniversalPrinter<T>::Print(value, ostream_ptr);
-//
-// A user can teach this function how to print a class type T by
-// defining either operator<<() or PrintTo() in the namespace that
-// defines T.  More specifically, the FIRST defined function in the
-// following list will be used (assuming T is defined in namespace
-// foo):
-//
-//   1. foo::PrintTo(const T&, ostream*)
-//   2. operator<<(ostream&, const T&) defined in either foo or the
-//      global namespace.
-//
-// However if T is an STL-style container then it is printed element-wise
-// unless foo::PrintTo(const T&, ostream*) is defined. Note that
-// operator<<() is ignored for container types.
-//
-// If none of the above is defined, it will print the debug string of
-// the value if it is a protocol buffer, or print the raw bytes in the
-// value otherwise.
-//
-// To aid debugging: when T is a reference type, the address of the
-// value is also printed; when T is a (const) char pointer, both the
-// pointer value and the NUL-terminated string it points to are
-// printed.
-//
-// We also provide some convenient wrappers:
-//
-//   // Prints a value to a string.  For a (const or not) char
-//   // pointer, the NUL-terminated string (but not the pointer) is
-//   // printed.
-//   std::string ::testing::PrintToString(const T& value);
-//
-//   // Prints a value tersely: for a reference type, the referenced
-//   // value (but not the address) is printed; for a (const or not) char
-//   // pointer, the NUL-terminated string (but not the pointer) is
-//   // printed.
-//   void ::testing::internal::UniversalTersePrint(const T& value, ostream*);
-//
-//   // Prints value using the type inferred by the compiler.  The difference
-//   // from UniversalTersePrint() is that this function prints both the
-//   // pointer and the NUL-terminated string for a (const or not) char pointer.
-//   void ::testing::internal::UniversalPrint(const T& value, ostream*);
-//
-//   // Prints the fields of a tuple tersely to a string vector, one
-//   // element for each field. Tuple support must be enabled in
-//   // gtest-port.h.
-//   std::vector<string> UniversalTersePrintTupleFieldsToStrings(
-//       const Tuple& value);
-//
-// Known limitation:
-//
-// The print primitives print the elements of an STL-style container
-// using the compiler-inferred type of *iter where iter is a
-// const_iterator of the container.  When const_iterator is an input
-// iterator but not a forward iterator, this inferred type may not
-// match value_type, and the print output may be incorrect.  In
-// practice, this is rarely a problem as for most containers
-// const_iterator is a forward iterator.  We'll fix this if there's an
-// actual need for it.  Note that this fix cannot rely on value_type
-// being defined as many user-defined container types don't have
-// value_type.

-// being part of the failure message.
-//
-// There are two different versions of this macro. EXPECT_NONFATAL_FAILURE only
-// affects and considers failures generated in the current thread and
-// EXPECT_NONFATAL_FAILURE_ON_ALL_THREADS does the same but for all threads.
-//
-// 'statement' is allowed to reference local variables and members of

-//
-// The verification of the assertion is done correctly even when the statement
-// throws an exception or aborts the current function.

-//   - You cannot stream a failure message to this macro.
-//
-// Note that even though the implementations of the following two
-// macros are much alike, we cannot refactor them to use a common
-// helper macro, due to some peculiarity in how the preprocessor
-// works.  If we do that, the code won't compile when the user gives
-// EXPECT_NONFATAL_FAILURE() a statement that contains a macro that
-// expands to code containing an unprotected comma.  The
-// AcceptsMacroThatExpandsToUnprotectedComma test in gtest_unittest.cc
-// catches that.
-//
-// For the same reason, we have to write

-
-#if 0
-
-// First, define a fixture class template.  It should be parameterized

-  T value_;
-};
-
-// Next, associate a list of types with the test case, which will be
-// repeated for each type in the list.  The typedef is necessary for
-// the macro to parse correctly.
-typedef testing::Types<char, int, unsigned int> MyTypes;
-TYPED_TEST_CASE(FooTest, MyTypes);
-
-// If the type list contains only one type, you can write that type
-// directly without Types<...>:
-//   TYPED_TEST_CASE(FooTest, int);
-
-// Then, use TYPED_TEST() instead of TEST_F() to define as many typed
-// tests for this test case as you want.
-TYPED_TEST(FooTest, DoesBlah) {
-  // Inside a test, refer to TypeParam to get the type parameter.
-  // Since we are inside a derived class template, C++ requires use to
-  // visit the members of FooTest via 'this'.
-  TypeParam n = this->value_;
-
-  // To visit static members of the fixture, add the TestFixture::
-  // prefix.
-  n += TestFixture::shared_;
-
-  // To refer to typedefs in the fixture, add the "typename
-  // TestFixture::" prefix.
-  typename TestFixture::List values;
-  values.push_back(n);
-  ...
-}
-
-TYPED_TEST(FooTest, HasPropertyA) { ... }
-
-// TYPED_TEST_CASE takes an optional third argument which allows to specify a
-// class that generates custom test name suffixes based on the type. This should
-// be a class which has a static template function GetName(int index) returning
-// a string for each type. The provided integer index equals the index of the
-// type in the provided type list. In many cases the index can be ignored.
-//
-// For example:
-//   class MyTypeNames {
-//    public:
-//     template <typename T>
-//     static std::string GetName(int) {
-//       if (std::is_same<T, char>()) return "char";
-//       if (std::is_same<T, int>()) return "int";
-//       if (std::is_same<T, unsigned int>()) return "unsignedInt";
-//     }

-
-// Type-parameterized tests are abstract test patterns parameterized
-// by a type.  Compared with typed tests, type-parameterized tests
-// allow you to define the test pattern without knowing what the type
-// parameters are.  The defined pattern can be instantiated with
-// different types any number of times, in any number of translation
-// units.
-//
-// If you are designing an interface or concept, you can define a
-// suite of type-parameterized tests to verify properties that any
-// valid implementation of the interface/concept should have.  Then,
-// each implementation can easily instantiate the test suite to verify
-// that it conforms to the requirements, without having to write
-// similar tests repeatedly.  Here's an example:
-
-#if 0
-
-// First, define a fixture class template.  It should be parameterized
-// by a type.  Remember to derive it from testing::Test.
-template <typename T>
-class FooTest : public testing::Test {
-  ...
-};

-// Next, declare that you will define a type-parameterized test case
-// (the _P suffix is for "parameterized" or "pattern", whichever you
-// prefer):
-TYPED_TEST_CASE_P(FooTest);
-
-// Then, use TYPED_TEST_P() to define as many type-parameterized tests
-// for this type-parameterized test case as you want.
-TYPED_TEST_P(FooTest, DoesBlah) {
-  // Inside a test, refer to TypeParam to get the type parameter.
-  TypeParam n = 0;
-  ...

-// you can instantiate them.  The first argument of the macro is the
-// test case name; the rest are the names of the tests in this test
-// case.
-REGISTER_TYPED_TEST_CASE_P(FooTest,
-                           DoesBlah, HasPropertyA);
-
-// Finally, you are free to instantiate the pattern with the types you
-// want.  If you put the above code in a header file, you can #include
-// it in multiple C++ source files and instantiate it multiple times.
-//
-// To distinguish different instances of the pattern, the first
-// argument to the INSTANTIATE_* macro is a prefix that will be added
-// to the actual test case name.  Remember to pick unique prefixes for
-// different instances.

-// A class for indicating whether an assertion was successful.  When
-// the assertion wasn't successful, the AssertionResult object
-// remembers a non-empty message that describes how it failed.
-//
-// To create an instance of this class, use one of the factory functions
-// (AssertionSuccess() and AssertionFailure()).
-//
-// This class is useful for two purposes:
-//   1. Defining predicate functions to be used with Boolean test assertions
-//      EXPECT_TRUE/EXPECT_FALSE and their ASSERT_ counterparts
-//   2. Defining predicate-format functions to be
-//      used with predicate assertions (ASSERT_PRED_FORMAT*, etc).
-//
-// For example, if you define IsEven predicate:
-//
-//   testing::AssertionResult IsEven(int n) {
-//     if ((n % 2) == 0)
-//       return testing::AssertionSuccess();
-//     else
-//       return testing::AssertionFailure() << n << " is odd";
-//   }
-//
-// Then the failed expectation EXPECT_TRUE(IsEven(Fib(5)))
-// will print the message
-//
-//   Value of: IsEven(Fib(5))
-//     Actual: false (5 is odd)
-//   Expected: true
-//
-// instead of a more opaque
-//
-//   Value of: IsEven(Fib(5))
-//     Actual: false
-//   Expected: true
-//
-// in case IsEven is a simple Boolean predicate.
-//
-// If you expect your predicate to be reused and want to support informative
-// messages in EXPECT_FALSE and ASSERT_FALSE (negative assertions show up
-// about half as often as positive ones in our tests), supply messages for
-// both success and failure cases:
-//
-//   testing::AssertionResult IsEven(int n) {
-//     if ((n % 2) == 0)
-//       return testing::AssertionSuccess() << n << " is even";
-//     else
-//       return testing::AssertionFailure() << n << " is odd";
-//   }
-//
-// Then a statement EXPECT_FALSE(IsEven(Fib(6))) will print
-//
-//   Value of: IsEven(Fib(6))
-//     Actual: true (8 is even)
-//   Expected: false
-//
-// NB: Predicates that support negative Boolean assertions have reduced
-// performance in positive ones so be careful not to use them in tests
-// that have lots (tens of thousands) of positive Boolean assertions.
-//
-// To use this class with EXPECT_PRED_FORMAT assertions such as:
-//
-//   // Verifies that Foo() returns an even number.
-//   EXPECT_PRED_FORMAT1(IsEven, Foo());
-//
-// you need to define:
-//
-//   testing::AssertionResult IsEven(const char* expr, int n) {
-//     if ((n % 2) == 0)
-//       return testing::AssertionSuccess();
-//     else
-//       return testing::AssertionFailure()
-//         << "Expected: " << expr << " is even\n  Actual: it's " << n;
-//   }
-//
-// If Foo() returns 5, you will see the following message:
-//
-//   Expected: Foo() is even
-//     Actual: it's 5

-//   Usage Guide.  Therefore, you are advised to use the

-//   equal.
-//
-//   2. The {ASSERT|EXPECT}_??() macros do pointer comparisons on
-//   pointers (in particular, C strings).  Therefore, if you use it
-//   with two C strings, you are testing how their locations in memory
-//   are related, not how their content is related.  To compare two C
-//   strings by content, use {ASSERT|EXPECT}_STR*().
-//
-//   3. {ASSERT|EXPECT}_EQ(v1, v2) is preferred to
-//   {ASSERT|EXPECT}_TRUE(v1 == v2), as the former tells you
-//   what the actual value is when it fails, and similarly for the

-// A "smart" pointer type with reference tracking.  Every pointer to a
-// particular object is kept on a circular linked list.  When the last pointer
-// to an object is destroyed or reassigned, the object is deleted.
-//
-// Used properly, this deletes the object when the last reference goes away.
-// There are several caveats:
-// - Like all reference counting schemes, cycles lead to leaks.
-// - Each smart pointer is actually two pointers (8 bytes instead of 4).
-// - Every time a pointer is assigned, the entire list of pointers to that
-//   object is traversed.  This class is therefore NOT SUITABLE when there
-//   will often be more than two or three pointers to a particular object.
-// - References are only tracked as long as linked_ptr<> objects are copied.
-//   If a linked_ptr<> is converted to a raw pointer and back, BAD THINGS
-//   will happen (double deletion).
-//
-// A good use of this class is storing object references in STL containers.
-// You can safely put linked_ptr<> in a vector<>.
-// Other uses may not be as good.
-//
-// Note: If you use an incomplete type with linked_ptr<>, the class
-// *containing* linked_ptr<> must have a constructor and destructor (even
-// if they do nothing!).
-//
-// Bill Gibbons suggested we use something like this.
-//
-// Thread Safety:
-//   Unlike other linked_ptr implementations, in this implementation
-//   a linked_ptr object is thread-safe in the sense that:
-//     - it's safe to copy linked_ptr objects concurrently,
-//     - it's safe to copy *from* a linked_ptr and read its underlying
-//       raw pointer (e.g. via get()) concurrently, and
-//     - it's safe to write to two linked_ptrs that point to the same
-//       shared object concurrently.
-// FIXME: rename this to safe_linked_ptr to avoid
-// confusion with normal linked_ptr.

-// Environment-describing macros
-// -----------------------------
-//
-// Google Test can be used in many different environments.  Macros in
-// this section tell Google Test what kind of environment it is being
-// used in, such that Google Test can provide environment-specific
-// features and implementations.
-//
-// Google Test tries to automatically detect the properties of its
-// environment, so users usually don't need to worry about these
-// macros.  However, the automatic detection is not perfect.
-// Sometimes it's necessary for a user to define some of the following
-// macros in the build script to override Google Test's decisions.
-//
-// If the user doesn't define a macro in the list, Google Test will
-// provide a default definition.  After this header is #included, all
-// macros in this list will be defined to either 1 or 0.
-//
-// Notes to maintainers:
-//   - Each macro here is a user-tweakable knob; do not grow the list
-//     lightly.
-//   - Use #if to key off these macros.  Don't use #ifdef or "#if
-//     defined(...)", which will not work as these macros are ALWAYS
-//     defined.
-//
-//   GTEST_HAS_CLONE          - Define it to 1/0 to indicate that clone(2)
-//                              is/isn't available.
-//   GTEST_HAS_EXCEPTIONS     - Define it to 1/0 to indicate that exceptions
-//                              are enabled.
-//   GTEST_HAS_GLOBAL_STRING  - Define it to 1/0 to indicate that ::string
-//                              is/isn't available
-//   GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::wstring
-//                              is/isn't available
-//   GTEST_HAS_POSIX_RE       - Define it to 1/0 to indicate that POSIX regular
-//                              expressions are/aren't available.
-//   GTEST_HAS_PTHREAD        - Define it to 1/0 to indicate that <pthread.h>
-//                              is/isn't available.
-//   GTEST_HAS_RTTI           - Define it to 1/0 to indicate that RTTI is/isn't
-//                              enabled.
-//   GTEST_HAS_STD_WSTRING    - Define it to 1/0 to indicate that
-//                              std::wstring does/doesn't work (Google Test can
-//                              be used where std::wstring is unavailable).
-//   GTEST_HAS_TR1_TUPLE      - Define it to 1/0 to indicate tr1::tuple
-//                              is/isn't available.
-//   GTEST_HAS_SEH            - Define it to 1/0 to indicate whether the
-//                              compiler supports Microsoft's "Structured
-//                              Exception Handling".
-//   GTEST_HAS_STREAM_REDIRECTION
-//                            - Define it to 1/0 to indicate whether the
-//                              platform supports I/O stream redirection using
-//                              dup() and dup2().
-//   GTEST_USE_OWN_TR1_TUPLE  - Define it to 1/0 to indicate whether Google
-//                              Test's own tr1 tuple implementation should be
-//                              used.  Unused when the user sets
-//                              GTEST_HAS_TR1_TUPLE to 0.
-//   GTEST_LANG_CXX11         - Define it to 1/0 to indicate that Google Test
-//                              is building in C++11/C++98 mode.
-//   GTEST_LINKED_AS_SHARED_LIBRARY
-//                            - Define to 1 when compiling tests that use
-//                              Google Test as a shared library (known as
-//                              DLL on Windows).
-//   GTEST_CREATE_SHARED_LIBRARY
-//                            - Define to 1 when compiling Google Test itself
-//                              as a shared library.
-//   GTEST_DEFAULT_DEATH_TEST_STYLE
-//                            - The default value of --gtest_death_test_style.
-//                              The legacy default has been "fast" in the open
-//                              source version since 2008. The recommended value
-//                              is "threadsafe", and can be set in

-// Platform-indicating macros
-// --------------------------
-//
-// Macros indicating the platform on which Google Test is being used
-// (a macro is defined to 1 if compiled on the given platform;
-// otherwise UNDEFINED -- it's never defined to 0.).  Google Test
-// defines these macros automatically.  Code outside Google Test MUST
-// NOT define them.
-//
-//   GTEST_OS_AIX      - IBM AIX
-//   GTEST_OS_CYGWIN   - Cygwin
-//   GTEST_OS_FREEBSD  - FreeBSD
-//   GTEST_OS_FUCHSIA  - Fuchsia
-//   GTEST_OS_HPUX     - HP-UX
-//   GTEST_OS_LINUX    - Linux
-//     GTEST_OS_LINUX_ANDROID - Google Android
-//   GTEST_OS_MAC      - Mac OS X
-//     GTEST_OS_IOS    - iOS
-//   GTEST_OS_NACL     - Google Native Client (NaCl)
-//   GTEST_OS_NETBSD   - NetBSD
-//   GTEST_OS_OPENBSD  - OpenBSD

-//   GTEST_OS_ZOS      - z/OS
-//
-// Among the platforms, Cygwin, Linux, Max OS X, and Windows have the
-// most stable support.  Since core members of the Google Test project
-// don't have access to other platforms, support for them may be less
-// stable.  If you notice any problems on your platform, please notify
-// googletestframework@googlegroups.com (patches for fixing them are
-// even more welcome!).
-//
-// It is possible that none of the GTEST_OS_* macros are defined.
-
-// Feature-indicating macros
-// -------------------------
-//
-// Macros indicating which Google Test features are available (a macro
-// is defined to 1 if the corresponding feature is supported;
-// otherwise UNDEFINED -- it's never defined to 0.).  Google Test
-// defines these macros automatically.  Code outside Google Test MUST
-// NOT define them.
-//
-// These macros are public so that portable tests can be written.
-// Such tests typically surround code using a feature with an #if
-// which controls that code.  For example:
-//
-// #if GTEST_HAS_DEATH_TEST
-//   EXPECT_DEATH(DoSomethingDeadly());
-// #endif
-//
-//   GTEST_HAS_COMBINE      - the Combine() function (for value-parameterized
-//                            tests)
-//   GTEST_HAS_DEATH_TEST   - death tests
-//   GTEST_HAS_TYPED_TEST   - typed tests
-//   GTEST_HAS_TYPED_TEST_P - type-parameterized tests
-//   GTEST_IS_THREADSAFE    - Google Test is thread-safe.
-//   GOOGLETEST_CM0007 DO NOT DELETE
-//   GTEST_USES_POSIX_RE    - enhanced POSIX regex is used. Do not confuse with
-//                            GTEST_HAS_POSIX_RE (see above) which users can
-//                            define themselves.
-//   GTEST_USES_SIMPLE_RE   - our own simple regex is used;
-//                            the above RE\b(s) are mutually exclusive.
-//   GTEST_CAN_COMPARE_NULL - accepts untyped NULL in EXPECT_EQ().
-
-// Misc public macros
-// ------------------
-//
-//   GTEST_FLAG(flag_name)  - references the variable corresponding to
-//                            the given Google Test flag.
-
-// Internal utilities
-// ------------------
-//
-// The following macros and utilities are for Google Test's INTERNAL
-// use only.  Code outside Google Test MUST NOT USE THEM DIRECTLY.
-//
-// Macros for basic C++ coding:
-//   GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning.
-//   GTEST_ATTRIBUTE_UNUSED_  - declares that a class' instances or a
-//                              variable don't have to be used.
-//   GTEST_DISALLOW_ASSIGN_   - disables operator=.
-//   GTEST_DISALLOW_COPY_AND_ASSIGN_ - disables copy ctor and operator=.
-//   GTEST_MUST_USE_RESULT_   - declares that a function's result must be used.
-//   GTEST_INTENTIONAL_CONST_COND_PUSH_ - start code section where MSVC C4127 is
-//                                        suppressed (constant conditional).
-//   GTEST_INTENTIONAL_CONST_COND_POP_  - finish code section where MSVC C4127
-//                                        is suppressed.
-//
-// C++11 feature wrappers:
-//
-//   testing::internal::forward - portability wrapper for std::forward.
-//   testing::internal::move  - portability wrapper for std::move.
-//
-// Synchronization:
-//   Mutex, MutexLock, ThreadLocal, GetThreadCount()
-//                            - synchronization primitives.
-//
-// Template meta programming:
-//   is_pointer     - as in TR1; needed on Symbian and IBM XL C/C++ only.
-//   IteratorTraits - partial implementation of std::iterator_traits, which
-//                    is not available in libCstd when compiled with Sun C++.
-//
-// Smart pointers:
-//   scoped_ptr     - as in TR2.
-//
-// Regular expressions:
-//   RE             - a simple regular expression class using the POSIX
-//                    Extended Regular Expression syntax on UNIX-like platforms
-//                    GOOGLETEST_CM0008 DO NOT DELETE
-//                    or a reduced regular exception syntax on other
-//                    platforms, including Windows.
-// Logging:
-//   GTEST_LOG_()   - logs messages at the specified severity level.
-//   LogToStderr()  - directs all log messages to stderr.
-//   FlushInfoLog() - flushes informational log messages.
-//
-// Stdout and stderr capturing:
-//   CaptureStdout()     - starts capturing stdout.
-//   GetCapturedStdout() - stops capturing stdout and returns the captured
-//                         string.

-// Implementation details of GTEST_COMPILE_ASSERT_:
-//
-// (In C++11, we simply use static_assert instead of the following)
-//
-// - GTEST_COMPILE_ASSERT_ works by defining an array type that has -1
-//   elements (and thus is invalid) when the expression is false.
-//
-// - The simpler definition
-//
-//    #define GTEST_COMPILE_ASSERT_(expr, msg) typedef char msg[(expr) ? 1 : -1]
-//
-//   does not work, as gcc supports variable-length arrays whose sizes
-//   are determined at run-time (this is gcc's extension and not part
-//   of the C++ standard).  As a result, gcc fails to reject the
-//   following code with the simple definition:
-//
-//     int foo;
-//     GTEST_COMPILE_ASSERT_(foo, msg); // not supposed to compile as foo is
-//                                      // not a compile-time constant.
-//
-// - By using the type CompileAssert<(bool(expr))>, we ensures that
-//   expr is a compile-time constant.  (Template arguments must be
-//   determined at compile-time.)
-//
-// - The outter parentheses in CompileAssert<(bool(expr))> are necessary
-//   to work around a bug in gcc 3.4.4 and 4.0.1.  If we had written
-//
-//     CompileAssert<bool(expr)>
-//
-//   instead, these compilers will refuse to compile
-//
-//     GTEST_COMPILE_ASSERT_(5 > 0, some_message);
-//
-//   (They seem to think the ">" in "5 > 0" marks the end of the
-//   template argument list.)
-//
-// - The array size is (bool(expr) ? 1 : -1), instead of simply
-//
-//     ((expr) ? 1 : -1).
-//
-//   This is to avoid running into a bug in MS VC 7.1, which

-// instead of an argument type convertable to a target type.
-//

-// how do you know the pointer is really of type SubclassOfFoo?  It
-// could be a bare Foo, or of type DifferentSubclassOfFoo.  Thus,
-// when you downcast, you should use this macro.  In debug mode, we
-// use dynamic_cast<> to double-check the downcast is legal (we die
-// if it's not).  In normal mode, we do the efficient static_cast<>

-// the cast is legal!
-//    This is the only place in the code we should use dynamic_cast<>.

-// will appear as Types<int, None, None, ..., None> in the compiler
-// errors).

-// Our solution is to combine the best part of the two approaches: a

-// that to TypesN<T1, ..., TN> internally to make error messages
-// readable.  The translation is done by the 'type' member of the

-// We don't want to require the users to write TemplatesN<...> directly,
-// as that would require them to count the length.  Templates<...> is much
-// easier to write, but generates horrible messages when there is a
-// compiler error, as gcc insists on printing out each template
-// argument, even if it has the default value (this means Templates<list>
-// will appear as Templates<list, NoneT, NoneT, ..., NoneT> in the compiler
-// errors).
-//
-// Our solution is to combine the best part of the two approaches: a
-// user would write Templates<T1, ..., TN>, and Google Test will translate
-// that to TemplatesN<T1, ..., TN> internally to make error messages
-// readable.  The translation is done by the 'type' member of the
-// Templates template.

-dnl @summary figure out how to build C programs using POSIX threads
-dnl
-dnl This macro figures out how to build C programs using POSIX threads.
-dnl It sets the PTHREAD_LIBS output variable to the threads library and
-dnl linker flags, and the PTHREAD_CFLAGS output variable to any special
-dnl C compiler flags that are needed. (The user can also force certain
-dnl compiler flags/libs to be tested by setting these environment
-dnl variables.)
-dnl
-dnl Also sets PTHREAD_CC to any special C compiler that is needed for
-dnl multi-threaded programs (defaults to the value of CC otherwise).
-dnl (This is necessary on AIX to use the special cc_r compiler alias.)
-dnl
-dnl NOTE: You are assumed to not only compile your program with these
-dnl flags, but also link it with them as well. e.g. you should link
-dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
-dnl $LIBS
-dnl
-dnl If you are only building threads programs, you may wish to use
-dnl these variables in your default LIBS, CFLAGS, and CC:
-dnl
-dnl        LIBS="$PTHREAD_LIBS $LIBS"
-dnl        CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
-dnl        CC="$PTHREAD_CC"
-dnl
-dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
-dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
-dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
-dnl
-dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
-dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to
-dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the
-dnl default action will define HAVE_PTHREAD.
-dnl
-dnl Please let the authors know if this macro fails on any platform, or
-dnl if you have any other suggestions or comments. This macro was based
-dnl on work by SGJ on autoconf scripts for FFTW (www.fftw.org) (with
-dnl help from M. Frigo), as well as ac_pthread and hb_pthread macros
-dnl posted by Alejandro Forero Cuervo to the autoconf macro repository.
-dnl We are also grateful for the helpful feedback of numerous users.

-// A sample program demonstrating using Google C++ testing framework.
-
-// This sample shows how to write a simple unit test for a function,
-// using Google C++ testing framework.
-//
-// Writing a unit test using Google C++ testing framework is easy as 1-2-3:
-
-
-// Step 1. Include necessary header files such that the stuff your
-// test logic needs is declared.
-//
-// Don't forget gtest.h, which declares the testing framework.
-
-#include <limits.h>
-#include "sample1.h"
-#include "gtest/gtest.h"
-namespace {
-
-// Step 2. Use the TEST macro to define your tests.
-//
-// TEST has two parameters: the test case name and the test name.
-// After using the macro, you should define your test logic between a
-// pair of braces.  You can use a bunch of macros to indicate the
-// success or failure of a test.  EXPECT_TRUE and EXPECT_EQ are
-// examples of such macros.  For a complete list, see gtest.h.
-//
-// <TechnicalDetails>
-//
-// In Google Test, tests are grouped into test cases.  This is how we
-// keep test code organized.  You should put logically related tests
-// into the same test case.
-//
-// The test case name and the test name should both be valid C++
-// identifiers.  And you should not use underscore (_) in the names.
-//
-// Google Test guarantees that each test you define is run exactly
-// once, but it makes no guarantee on the order the tests are
-// executed.  Therefore, you should write your tests in such a way
-// that their results don't depend on their order.
-//
-// </TechnicalDetails>
-
-

-  // test case.
-  EXPECT_EQ(1, Factorial(-5));

-  EXPECT_GT(Factorial(-10), 0);
-
-  // <TechnicalDetails>
-  //
-  // EXPECT_EQ(expected, actual) is the same as
-  //
-  //   EXPECT_TRUE((expected) == (actual))
-  //
-  // except that it will print both the expected value and the actual
-  // value when the assertion fails.  This is very helpful for
-  // debugging.  Therefore in this case EXPECT_EQ is preferred.
-  //
-  // On the other hand, EXPECT_TRUE accepts any Boolean expression,
-  // and is thus more general.

-// A sample program demonstrating using Google C++ testing framework.
-
-// In this example, we use a more advanced feature of Google Test called
-// test fixture.
-//
-// A test fixture is a place to hold objects and functions shared by
-// all tests in a test case.  Using a test fixture avoids duplicating
-// the test code necessary to initialize and cleanup those common
-// objects for each test.  It is also useful for defining sub-routines
-// that your tests need to invoke a lot.
-//
-// <TechnicalDetails>
-//
-// The tests share the test fixture in the sense of code sharing, not
-// data sharing.  Each test is given its own fresh copy of the
-// fixture.  You cannot expect the data modified by one test to be
-// passed on to another test, which is a bad idea.
-//
-// The reason for this design is that tests should be independent and
-// repeatable.  In particular, a test should not fail as the result of
-// another test's failure.  If one test depends on info produced by
-// another test, then the two tests should really be one big test.
-//
-// The macros for indicating the success/failure of a test
-// (EXPECT_TRUE, FAIL, etc) need to know what the current test is
-// (when Google Test prints the test result, it tells you which test
-// each failure belongs to).  Technically, these macros invoke a
-// member function of the Test class.  Therefore, you cannot use them
-// in a global function.  That's why you should put test sub-routines
-// in a test fixture.

-// make sure that all tests for a GUI library don't leak important
-// system resources like fonts and brushes.  In Google Test, you do

-// test fixture, and then have each test case use a fixture derived

-"""fuse_gtest_files.py v0.2.0
-Fuses Google Test source code into a .h file and a .cc file.
-
-SYNOPSIS
-       fuse_gtest_files.py [GTEST_ROOT_DIR] OUTPUT_DIR
-
-       Scans GTEST_ROOT_DIR for Google Test source code, and generates
-       two files: OUTPUT_DIR/gtest/gtest.h and OUTPUT_DIR/gtest/gtest-all.cc.
-       Then you can build your tests by adding OUTPUT_DIR to the include
-       search path and linking with OUTPUT_DIR/gtest/gtest-all.cc.  These
-       two files contain everything you need to use Google Test.  Hence
-       you can "install" Google Test by copying them to wherever you want.
-
-       GTEST_ROOT_DIR can be omitted and defaults to the parent
-       directory of the directory holding this script.
-
-EXAMPLES
-       ./fuse_gtest_files.py fused_gtest
-       ./fuse_gtest_files.py path/to/unpacked/gtest fused_gtest
-
-This tool is experimental.  In particular, it assumes that there is no
-conditional inclusion of Google Test headers.  Please report any
-problems to googletestframework@googlegroups.com.  You can read
-https://github.com/google/googletest/blob/master/googletest/docs/advanced.md for

-The `gtest-config' script provides access to the necessary compile and linking
-flags to connect with Google C++ Testing Framework, both in a build prior to
-installation, and on the system proper after installation. The installation
-overrides may be issued in combination with any other queries, but will only
-affect installation queries if called on a built but not installed gtest. The
-installation queries may not be issued with any other types of queries, and
-only one installation query may be made at a time. The version queries and
-compiler flag queries may be combined as desired but not mixed. Different
-version queries are always combined with logical "and" semantics, and only the
-last of any particular query is used while all previous ones ignored. All
-versions must be specified as a sequence of numbers separated by periods.
-Compiler flag queries output the union of the sets of flags when combined.
-
- Examples:
-  gtest-config --min-version=1.0 || echo "Insufficient Google Test version."
-
-  g++ $(gtest-config --cppflags --cxxflags) -o foo.o -c foo.cpp
-  g++ $(gtest-config --ldflags --libs) -o foo foo.o
-
-  # When using a built but not installed Google Test:
-  g++ $(../../my_gtest_build/scripts/gtest-config ...) ...
-
-  # When using an installed Google Test, but with installation overrides:
-  export GTEST_PREFIX="/opt"
-  g++ $(gtest-config --libdir="/opt/lib64" ...) ...

-  --libdir                   library installation directory
-  --includedir               header file installation directory
-  --version                  the version of the Google Test installation
-

-  --min-version=VERSION      return 0 if the version is at least VERSION
-  --exact-version=VERSION    return 0 if the version is exactly VERSION
-  --max-version=VERSION      return 0 if the version is at most VERSION

-"""Script for branching Google Test/Mock wiki pages for a new version.
-
-SYNOPSIS
-       release_docs.py NEW_RELEASE_VERSION
-
-       Google Test and Google Mock's external user documentation is in
-       interlinked wiki files.  When we release a new version of
-       Google Test or Google Mock, we need to branch the wiki files
-       such that users of a specific version of Google Test/Mock can
-       look up documenation relevant for that version.  This script
-       automates that process by:
-
-         - branching the current wiki pages (which document the
-           behavior of the SVN trunk head) to pages for the specified
-           version (e.g. branching FAQ.wiki to V2_6_FAQ.wiki when
-           NEW_RELEASE_VERSION is 2.6);
-         - updating the links in the branched files to point to the branched
-           version (e.g. a link in V2_6_FAQ.wiki that pointed to
-           Primer.wiki#Anchor will now point to V2_6_Primer.wiki#Anchor).
-
-       NOTE: NEW_RELEASE_VERSION must be a NEW version number for
-       which the wiki pages don't yet exist; otherwise you'll get SVN
-       errors like "svn: Path 'V1_7_PumpManual.wiki' is not a
-       directory" when running the script.
-
-EXAMPLE
-       $ cd PATH/TO/GTEST_SVN_WORKSPACE/trunk
-       $ scripts/release_docs.py 2.6  # create wiki pages for v2.6
-       $ svn status                   # verify the file list
-       $ svn diff                     # verify the file contents
-       $ svn commit -m "release wiki pages for v2.6"

-// A few implementation notes:  Like the Linux version, the Windows
-// implementation uses pipes for child-to-parent communication. But due to
-// the specifics of pipes on Windows, some extra steps are required:
-//
-// 1. The parent creates a communication pipe and stores handles to both
-//    ends of it.
-// 2. The parent starts the child and provides it with the information
-//    necessary to acquire the handle to the write end of the pipe.
-// 3. The child acquires the write end of the pipe and signals the parent
-//    using a Windows event.
-// 4. Now the parent can release the write end of the pipe on its side. If
-//    this is done before step 3, the object's reference count goes down to
-//    0 and it is destroyed, preventing the child from acquiring it. The
-//    parent now has to release it, or read operations on the read end of
-//    the pipe will not return when the child terminates.
-// 5. The parent reads child's output through the pipe (outcome code and
-//    any possible error messages) from the pipe, and its stderr and then
-//    determines whether to fail the test.

-// Note: to distinguish Win32 API calls from the local method and function

-"""Unit test for Google Test test filters.
-
-A user can specify which test(s) in a Google Test program to run via either
-the GTEST_FILTER environment variable or the --gtest_filter flag.
-This script tests such functionality by invoking
-googletest-filter-unittest_ (a program written with Google Test) with different
-environments and command line flags.
-
-Note that test sharding may also influence which tests are filtered. Therefore,
-we test that here also.

-"""A script to prepare version information for use the gtest Info.plist file.
-
-  This script extracts the version information from the configure.ac file and
-  uses it to generate a header file containing the same information. The
-  #defines in this header file will be included in during the generation of
-  the Info.plist of the framework, giving the correct value to the version
-  shown in the Finder.
-
-  This script makes the following assumptions (these are faults of the script,
-  not problems with the Autoconf):
-    1. The AC_INIT macro will be contained within the first 1024 characters
-       of configure.ac
-    2. The version string will be 3 integers separated by periods and will be
-       surrounded by square brackets, "[" and "]" (e.g. [1.0.1]). The first
-       segment represents the major version, the second represents the minor
-       version and the third represents the fix version.
-    3. No ")" character exists between the opening "(" and closing ")" of
-       AC_INIT, including in comments and character strings.
