 *   [CMake](https://cmake.org/) v2.8.12 or newer

@@ -101,30 +102,40 @@ To make sure your changes work as intended and don't break existing
 functionality, you'll want to compile and run Google Test and GoogleMock's own
 tests. For that you can use CMake:

-    mkdir mybuild
-    cd mybuild
-    cmake -Dgtest_build_tests=ON -Dgmock_build_tests=ON ${GTEST_REPO_DIR}
+```
+mkdir mybuild
+cd mybuild
+cmake -Dgtest_build_tests=ON -Dgmock_build_tests=ON ${GTEST_REPO_DIR}
+```

 To choose between building only Google Test or Google Mock, you may modify your
 cmake command to be one of each

-    cmake -Dgtest_build_tests=ON ${GTEST_DIR} # sets up Google Test tests
-    cmake -Dgmock_build_tests=ON ${GMOCK_DIR} # sets up Google Mock tests
+```
+cmake -Dgtest_build_tests=ON ${GTEST_DIR} # sets up Google Test tests
+cmake -Dgmock_build_tests=ON ${GMOCK_DIR} # sets up Google Mock tests
+```

 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 ...
+```
+cmake -DPYTHON_EXECUTABLE=path/to/python ...
+```

 Next, you can build Google Test and / or Google Mock and all desired tests. On
 \*nix, this is usually done by

-    make
+```
+make
+```

 To run the tests, do

-    make test
+```
+make test
+```

 All tests should pass.

+### Distributing Test Functions to Multiple Machines
+
+If you have more than one machine you can use to run a test program, you might
+want to run the test functions in parallel and get the result faster. We call
+this technique *sharding*, where each machine is called a *shard*.
+
+GoogleTest is compatible with test sharding. To take advantage of this feature,
+your test runner (not part of GoogleTest) needs to do the following:
+
+1.  Allocate a number of machines (shards) to run the tests.
+1.  On each shard, set the `GTEST_TOTAL_SHARDS` environment variable to the total
+    number of shards. It must be the same for all shards.
+1.  On each shard, set the `GTEST_SHARD_INDEX` environment variable to the index
+    of the shard. Different shards must be assigned different indices, which
+    must be in the range `[0, GTEST_TOTAL_SHARDS - 1]`.
+1.  Run the same test program on all shards. When GoogleTest sees the above two
+    environment variables, it will select a subset of the test functions to run.
+    Across all shards, each test function in the program will be run exactly
+    once.
+1.  Wait for all shards to finish, then collect and report the results.
+
+Your project may have tests that were written without GoogleTest and thus don't
+understand this protocol. In order for your test runner to figure out which test
+supports sharding, it can set the environment variable `GTEST_SHARD_STATUS_FILE`
+to a non-existent file path. If a test program supports sharding, it will create
+this file to acknowledge that fact; otherwise it will not create it. The actual
+contents of the file are not important at this time, although we may put some
+useful information in it in the future.
+
+Here's an example to make it clear. Suppose you have a test program `foo_test`
+that contains the following 5 test functions:
+
+```
+TEST(A, V)
+TEST(A, W)
+TEST(B, X)
+TEST(B, Y)
+TEST(B, Z)
+```
+
+Suppose you have 3 machines at your disposal. To run the test functions in
+parallel, you would set `GTEST_TOTAL_SHARDS` to 3 on all machines, and set
+`GTEST_SHARD_INDEX` to 0, 1, and 2 on the machines respectively. Then you would
+run the same `foo_test` on each machine.
+
+GoogleTest reserves the right to change how the work is distributed across the
+shards, but here's one possible scenario:
+
+*   Machine #0 runs `A.V` and `B.X`.
+*   Machine #1 runs `A.W` and `B.Y`.

+### Writing New Actions {#QuickNewActions}

 If the built-in actions don't work for you, you can easily define your own one.
-Just define a functor class with a (possibly templated) call operator, matching
-the signature of your action.
+All you need is a call operator with a signature compatible with the mocked
+function. So you can use a lambda:

 ```cpp
-struct Increment {
-  template <typename T>
-  T operator()(T* arg) {
-    return ++(*arg);
-  }
-}
+MockFunction<int(int)> mock;
+EXPECT_CALL(mock, Call).WillOnce([](const int input) { return input * 7; });
+EXPECT_EQ(mock.AsStdFunction()(2), 14);
 ```

-The same approach works with stateful functors (or any callable, really):
+Or a struct with a call operator (even a templated one):

-```
+```cpp
 struct MultiplyBy {
  template <typename T>
  T operator()(T arg) { return arg * multiplier; }

  int multiplier;
-}
+};

 // Then use:
 // EXPECT_CALL(...).WillOnce(MultiplyBy{7});
 ```

+It's also fine for the callable to take no arguments, ignoring the arguments
+supplied to the mock function:
+
+```cpp
+MockFunction<int(int)> mock;
+EXPECT_CALL(mock, Call).WillOnce([] { return 17; });
+EXPECT_EQ(mock.AsStdFunction()(0), 17);
+```
+
+When used with `WillOnce`, the callable can assume it will be called at most
+once and is allowed to be a move-only type:
+
+```cpp
+// An action that contains move-only types and has an &&-qualified operator,
+// demanding in the type system that it be called at most once. This can be
+// used with WillOnce, but the compiler will reject it if handed to
+// WillRepeatedly.
+struct MoveOnlyAction {
+  std::unique_ptr<int> move_only_state;
+  std::unique_ptr<int> operator()() && { return std::move(move_only_state); }
+};
+
+MockFunction<std::unique_ptr<int>()> mock;
+EXPECT_CALL(mock, Call).WillOnce(MoveOnlyAction{std::make_unique<int>(17)});
+EXPECT_THAT(mock.AsStdFunction()(), Pointee(Eq(17)));
+```
+
+More generally, to use with a mock function whose signature is `R(Args...)` the
+object can be anything convertible to `OnceAction<R(Args...)>` or
+`Action<R(Args...)`>. The difference between the two is that `OnceAction` has
+weaker requirements (`Action` requires a copy-constructible input that can be
+called repeatedly whereas `OnceAction` requires only move-constructible and
+supports `&&`-qualified call operators), but can be used only with `WillOnce`.
+`OnceAction` is typically relevant only when supporting move-only types or
+actions that want a type-system guarantee that they will be called at most once.
+
+Typically the `OnceAction` and `Action` templates need not be referenced
+directly in your actions: a struct or class with a call operator is sufficient,
+as in the examples above. But fancier polymorphic actions that need to know the
+specific return type of the mock function can define templated conversion
+operators to make that possible. See `gmock-actions.h` for examples.

-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/docs/gmock_cook_book.md
-for more
-information.

-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing

-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)
-
-
-Contact:
--------
-  If you used cppclean, I would love to hear about your experiences
-  cppclean@googlegroups.com.  Even if you don't use cppclean, I'd like to
-  hear from you.  :-)  (You can contact me directly at:  nnorwitz@gmail.com)
