Subject: Use pcfiledir for prefix in pkgconfig file

Using absolute paths in the pkg-config file makes it not relocatable and
leads to problems, when trying to use it with precompiled cross
toolchains. Setting prefix to relative path based on pcfiledir makes it
more reliable for such cases.

-// 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.

+// 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.

Subject: Googletest export

[Fuchsia] Make the child process stderr redirection use a socket.

This changes the stderr redirection mechanism for the child process in Fuchsia death tests to use a Zircon socket rather than fd redirection. This should improve performance and reliability of the redirection process.
This also includes some minor style cleanups.

-// 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.

[Fuchsia] Create the death test child process in a separate job.

This creates a separate job to launch the child process into. The
exception port can then be attached to the new job before the child
process is launched, solving a potential race condition.

Improve Bazel build files.

New target gtest_prod allows access to the FRIEND_TEST macro without depending on the entirety of GTest in production executables. Additionally, duplicate config_setting rules were removed and formatting was adjusted.

-// A MockFunction<F> class has one mock method whose type is F.  It is

-//   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;

-// 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

-// TEST(FooTest, RunsCallbackWithBarArgument) {

-// A MockFunction<F> class has one mock method whose type is F.  It is

-// 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;

-//
-// MockFunction<F> can also be used to exercise code that accepts
-// std::function<F> callbacks. To do so, use AsStdFunction() method

+// 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());

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at titus@google.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html
+
+[homepage]: https://www.contributor-covenant.org

+For answers to common questions about this code of conduct, see

-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-In the interest of fostering an open and welcoming environment, we as
-contributors and maintainers pledge to making participation in our project and
-our community a harassment-free experience for everyone, regardless of age, body
-size, disability, ethnicity, sex characteristics, gender identity and expression,
-level of experience, education, socio-economic status, nationality, personal
-appearance, race, religion, or sexual identity and orientation.
-
-## Our Standards
-
-Examples of behavior that contributes to creating a positive environment
-include:
-
-* Using welcoming and inclusive language
-* Being respectful of differing viewpoints and experiences
-* Gracefully accepting constructive criticism
-* Focusing on what is best for the community
-* Showing empathy towards other community members
-
-Examples of unacceptable behavior by participants include:
-
-* The use of sexualized language or imagery and unwelcome sexual attention or
- advances
-* Trolling, insulting/derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or electronic
- address, without explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
- professional setting
-
-## Our Responsibilities
-
-Project maintainers are responsible for clarifying the standards of acceptable
-behavior and are expected to take appropriate and fair corrective action in
-response to any instances of unacceptable behavior.
-
-Project maintainers have the right and responsibility to remove, edit, or
-reject comments, commits, code, wiki edits, issues, and other contributions
-that are not aligned to this Code of Conduct, or to ban temporarily or
-permanently any contributor for other behaviors that they deem inappropriate,
-threatening, offensive, or harmful.
-
-## Scope
-
-This Code of Conduct applies both within project spaces and in public spaces
-when an individual is representing the project or its community. Examples of
-representing a project or community include using an official project e-mail
-address, posting via an official social media account, or acting as an appointed
-representative at an online or offline event. Representation of a project may be
-further defined and clarified by project maintainers.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported by contacting the project team at titus@google.com. All
-complaints will be reviewed and investigated and will result in a response that
-is deemed necessary and appropriate to the circumstances. The project team is
-obligated to maintain confidentiality with regard to the reporter of an incident.
-Further details of specific enforcement policies may be posted separately.
-
-Project maintainers who do not follow or enforce the Code of Conduct in good
-faith may face temporary or permanent repercussions as determined by other
-members of the project's leadership.
-
-## Attribution
-
-This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
-available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

Subject: Googletest export

The gmock matchers have a concept of MatchAndExpain; where the details of the
matching are written to a "result listener". A matcher can avoid creating
expensive debug info by checking result_listener->IsInterested(); but,
unfortunately, the default matcher code (called from EXPECT_THAT) is always
"interested".

This change implements EXPECT_THAT matching to first run the matcher in a "not
interested" mode; and then run it a second time ("interested") only if the
match fails.

Subject: Googletest export

The gmock matchers have a concept of MatchAndExpain; where the details of the
matching are written to a "result listener". A matcher can avoid creating
expensive debug info by checking result_listener->IsInterested(); but,
unfortunately, the default matcher code (called from EXPECT_THAT) is always
"interested".

This change implements EXPECT_THAT matching to first run the matcher in a "not
interested" mode; and then run it a second time ("interested") only if the
match fails.

Use std::function to implement type erasure in Action, wrapping the legacy
ActionInterface if necessary.

This makes functors / std::function the primary way to implement Action; the
existing ActionInterface implementations are handled through ActionAdaptor.
The existing actions are not (yet) migrated though; they'll pay the cost of one
additional indirection - but that should be negligible.

Subject: Googletest export

Get rid of code generation for NiceMock / StrictMock.
They got small enough that it doesn't make sense to generate them.

-// 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.
