+# FMT Fuzzer
+
+Fuzzing has revealed [several bugs](https://github.com/fmtlib/fmt/issues?&q=is%3Aissue+fuzz)
+in fmt. It is a part of the continous fuzzing at
+[oss-fuzz](https://github.com/google/oss-fuzz).
+
+The source code is modified to make the fuzzing possible without locking up on
+resource exhaustion:
+```cpp
+#ifdef FMT_FUZZ
+if(spec.precision>100000) {
+ throw std::runtime_error("fuzz mode - avoiding large precision");
+}
+#endif
+```
+This macro `FMT_FUZZ` is enabled on OSS-Fuzz builds and makes fuzzing
+practically possible. It is used in fmt code to prevent resource exhaustion in
+fuzzing mode.
+The macro `FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION` is the
+defacto standard for making fuzzing practically possible to disable certain
+fuzzing-unfriendly features (for example, randomness), see [the libFuzzer
+documentation](https://llvm.org/docs/LibFuzzer.html#fuzzer-friendly-build-mode).
+
+## Running the fuzzers locally
+
+There is a [helper script](build.sh) to build the fuzzers, which has only been
+tested on Debian and Ubuntu linux so far. There should be no problems fuzzing on
+Windows (using clang>=8) or on Mac, but the script will probably not work out of
+the box.
+
+Something along
+```sh
+mkdir build
+cd build
+export CXX=clang++
+export CXXFLAGS="-fsanitize=fuzzer-no-link -DFUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION= -g"
+cmake .. -DFMT_SAFE_DURATION_CAST=On -DFMT_FUZZ=On -DFMT_FUZZ_LINKMAIN=Off -DFMT_FUZZ_LDFLAGS="-fsanitize=fuzzer"
+cmake --build .
+```
+should work to build the fuzzers for all platforms which clang supports.
+
+Execute a fuzzer with for instance
+```sh
+cd build
+export UBSAN_OPTIONS=halt_on_error=1
+mkdir out_chrono
+bin/fuzzer_chrono_duration out_chrono
+```

+//
+// 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
+// calls, the former are explicitly resolved in the global namespace.

+// 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

+
+// 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.

+// 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(std::tr1::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

+// Notes:
+//
+// 1. The arguments are passed by value by default. If you need to

+// 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

+// 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

+// 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, with up-to 10 arguments. 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.
+//
+// Another known limitation is that the constructors of the base mock
+// cannot have arguments passed by non-const reference, which are
+// banned by the Google C++ style guide anyway.

+
+
+// 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,
+// 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.
+//
+// More Information
+// ================

+//
+// 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 (some systems define
+// ::string, which is different to std::string).
+// GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::string
+// is/isn't available (some systems define
+// ::wstring, which is different to std::wstring).
+// 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.
+
+// This header defines the following utilities:
+//
+// Macros indicating the current platform (defined to 1 if compiled on
+// the given platform; otherwise undefined):

+// don't have access to other platforms, support for them may be less
+// stable. If you notice any problems on your platform, please notify

+//
+// Synchronization:
+// Mutex, MutexLock, ThreadLocal, GetThreadCount()
+// - synchronization primitives.
+// GTEST_IS_THREADSAFE - defined to 1 to indicate that the above
+// synchronization primitives have real implementations
+// and Google Test is thread-safe; or 0 otherwise.
+//
+// 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++.

+// string.
+// CaptureStderr() - starts capturing stderr.
+// GetCapturedStderr() - stops capturing stderr and returns the captured
+// string.
+//
+// Integer types:
+// TypeWithSize - maps an integer to a int type.
+// Int32, UInt32, Int64, UInt64, TimeInMillis
+// - integers of known sizes.
+// BiggestInt - the biggest signed integer type.
+//
+// Command-line utilities:
+// GTEST_FLAG() - references a flag.
+// GTEST_DECLARE_*() - declares a flag.
+// GTEST_DEFINE_*() - defines a flag.

+// 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.

+// 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.

+//
+// 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:
+//
+// On POSIX-compliant systems (*nix), we use the <regex.h> library,
+// which uses the POSIX extended regex syntax.
+//
+// On other platforms (e.g. Windows), 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.
+//

+// Value-parameterized tests allow you to test your code with different
+// parameters without writing multiple copies of the same test.
+//
+// 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) {
+ // 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. 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));
+
+// 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.
+//
+// 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()));

+// 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.
+// TODO(wan@google.com): rename this to safe_linked_ptr to avoid
+// confusion with normal linked_ptr.

+// 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.
+//
+// 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.

+// Google Test uses these generators to produce parameters for value-
+// parameterized tests. When a parameterized test case is instantiated
+// with a particular generator, Google Test creates and runs tests
+// for each element in the sequence produced by the generator.
+//
+// In the following sample, tests from test case FooTest are instantiated
+// each three times with parameter values 3, 5, and 8:
+//
+// class FooTest : public TestWithParam<int> { ... };
+//
+// TEST_P(FooTest, TestThis) {

+// }

+
+// Range() returns generators providing sequences of values in a range.
+//
+// Synopsis:
+// Range(start, end)
+// - returns a generator producing a sequence of values {start, start+1,
+// start+2, ..., }.
+// Range(start, end, step)
+// - returns a generator producing a sequence of values {start, start+step,
+// start+step+step, ..., }.
+// Notes:
+// * The generated sequences never include end. For example, Range(1, 5)
+// returns a generator producing a sequence {1, 2, 3, 4}. Range(1, 9, 2)
+// returns a generator producing {1, 3, 5, 7}.
+// * start and end must have the same type. That type may be any integral or
+// floating-point type or a user defined type satisfying these conditions:
+// * It must be assignable (have operator=() defined).
+// * It must have operator+() (operator+(int-compatible type) for
+// two-operand version).
+// * It must have operator<() defined.
+// Elements in the resulting sequences will also have that type.
+// * Condition start < end must be satisfied in order for resulting sequences
+// to contain any elements.

+// - returns a generator producing sequences with elements coming from

+// Combine can have up to 10 arguments. This number is currently limited
+// by the maximum number of elements in the tuple implementation used by Google
+// Test.
+//
+// Example:
+//
+// This will instantiate tests in test case AnimalTest each one with

+// INSTANTIATE_TEST_CASE_P(AnimalVariations, AnimalTest,
+// Combine(Values("cat", "dog"),
+// Values(BLACK, WHITE)));
+//
+// This will instantiate tests in FlagDependentTest with all variations of two
+// Boolean flags:
+//
+// class FlagDependentTest
+// : public testing::TestWithParam<tuple<bool, bool> > {
+// virtual void SetUp() {
+// // Assigns external_flag_1 and external_flag_2 values from the tuple.
+// tie(external_flag_1, external_flag_2) = GetParam();

+// This header implements typed tests and type-parameterized tests.
+
+// Typed (aka type-driven) tests repeat the same test for types in a
+// list. You must know which types you want to test with when writing
+// typed tests. Here's how you do it:
+
+#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 {
+ 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. 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) { ... }
+
+#endif // 0
+
+// 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;
+ ...
+}
+
+TYPED_TEST_P(FooTest, HasPropertyA) { ... }
+
+// Now the tricky part: you need to register all test patterns 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.
+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

+// 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

+//
+// Note:
+//
+// 1. It is possible to make a user-defined type work with
+// {ASSERT|EXPECT}_??(), but that requires overloading the
+// comparison operators and is thus discouraged by the Google C++
+// Usage Guide. Therefore, you are advised to use the
+// {ASSERT|EXPECT}_TRUE() macro to assert that two objects are
+// 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(expected, actual) is preferred to
+// {ASSERT|EXPECT}_TRUE(expected == actual), as the former tells you
+// what the actual value is when it fails, and similarly for the
+// other comparisons.
