-// 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

-// 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.

-// 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.

-// 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());
-// }

-//   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.

-// required to avoid compile errors when the name of the method used in call is
-// a result of macro expansion. See CompilesWithMethodNameExpandedFromMacro
-// tests in internal/gmock-spec-builders_test.cc for more details.
-//
-// This macro supports statements both with and without parameter matchers. If
-// the parameter list is omitted, gMock will accept any parameters, which allows
-// tests to be written that don't need to encode the number of method
-// parameter. This technique may only be used for non-overloaded methods.
-//
-//   // These are the same:
-//   ON_CALL(mock, NoArgsMethod()).WillByDefault(...);
-//   ON_CALL(mock, NoArgsMethod).WillByDefault(...);
-//
-//   // As are these:
-//   ON_CALL(mock, TwoArgsMethod(_, _)).WillByDefault(...);
-//   ON_CALL(mock, TwoArgsMethod).WillByDefault(...);
-//
-//   // Can also specify args if you want, of course:
-//   ON_CALL(mock, TwoArgsMethod(_, 45)).WillByDefault(...);
-//
-//   // Overloads work as long as you specify parameters:
-//   ON_CALL(mock, OverloadedMethod(_)).WillByDefault(...);
-//   ON_CALL(mock, OverloadedMethod(_, _)).WillByDefault(...);
-//
-//   // Oops! Which overload did you want?
-//   ON_CALL(mock, OverloadedMethod).WillByDefault(...);
-//     => ERROR: call to member function 'gmock_OverloadedMethod' is ambiguous
-//
-// 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)...
-//   |-----------------------v--------------------------|
-//                 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
-// is how we block callers from setting expectations on overloaded methods.

-// 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

-// The following macros are useful for writing death tests.
-
-// Here's what happens when an ASSERT_DEATH* or EXPECT_DEATH* is
-// executed:
-//
-//   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.
-//
-// FIXME: make thread-safe death tests search the PATH.

-// This macro is used for implementing macros such as

-// 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

-// Value-parameterized tests allow you to test your code with different

-//
-// 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

-// 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:

-// Functions producing parameter generators.
-//
-// 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) {
-// }
-// TEST_P(FooTest, TestThat) {
-// }
-// INSTANTIATE_TEST_CASE_P(TestSequence, FooTest, Values(3, 5, 8));

-// 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.

-//
-// Synopsis:

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

-// ValuesIn(const Container& container)
-//   - returns a generator producing sequences with elements from

-// ValuesIn(Iterator begin, Iterator end)

-//     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

-//
-// 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;

-//
-//
-// 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');

-// Synopsis:

-//   - returns a generator producing sequences with elements coming from
-//     the Cartesian product of elements from the sequences generated by

-// 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
-// the parameter values tuple("cat", BLACK), tuple("cat", WHITE),
-// tuple("dog", BLACK), and tuple("dog", WHITE):
-//
-// enum Color { BLACK, GRAY, 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.

-// 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()));

-// Notes:
-//   * The generated sequences never include end. For example, Range(1, 5)

-//     returns a generator producing {1, 3, 5, 7}.

-
-#if 0

-// 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.

-  // 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.

-// If the type list contains only one type, you can write that type
-// directly without Types<...>:

-// 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

-//
-//   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).

-//                            - 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

-//
-// 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

-//
-// Among the platforms, Cygwin, Linux, Max OS X, and Windows have the

-// 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.

-//                            - synchronization primitives.
-//
-// Template meta programming:

-// - 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).

-// 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

-// compiler error, as gcc insists on printing out each template
-// argument, even if it has the default value (this means Types<int>
-// 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
-// user would write Types<T1, ..., TN>, and Google Test will translate
-// 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.

-//    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
