Explicitly define copy constructors used in googletest tests
As of C++11, providing a user-declared copy assignment operator should
suppress the availability of an implicit default copy constructor.
Classes that provide (or delete) a copy assignment operator must provide
their own copy constructor if one is desired. This may be an explicit
default copy constructor if appropriate.
As googletest is a C++11 codebase, this change should be made without
qualification.
This addresses the -Wdeprecated-copy warnings issued by trunk clang:
While compiling googletest/test/googletest-death-test-test.cc:

This matches other changes made elsewhere in the googletest codebase,
such as 306f3754a7. Perhaps those previous changes did not consider
test code.

None of these are strictly needed for correctness.
A large number of them (maybe all of them?) trigger `-Wdeprecated`
warnings on Clang trunk as soon as you try to use the implicitly
defaulted (but deprecated) copy constructor of a class that has
deleted its copy assignment operator.
By declaring a deleted copy assignment operator, the old code
also caused the move constructor and move assignment operator
to be non-declared. This means that the old code never got move
semantics -- "move-construction" would simply call the defaulted
(but deprecated) copy constructor instead. With the new code,
"move-construction" calls the defaulted move constructor, which
I believe is what we want to happen. So this is a runtime
performance optimization.
Unfortunately we can't yet physically remove the definitions
of these macros from gtest-port.h, because they are being used
by other code internally at Google (according to zhangxy988).
But no new uses should be added going forward.
This change updates testing::internal::IsAProtocolMessage to return true not
just for full proto messages but also for lite ones (i.e. those inheriting
directly from MessageLite).

The extra tests check that the xml output is correct when a failure occurs before skipping, and that the right skip message is added to the file.
The json file had to be fixed because it's the same executable.
Add --gtest_fail_fast support to googletest.
- Analogous functionality to to golang -test.failfast and python --failfast
- Stops test execution upon first test failure.
- Also add support Bazel equivalent env var (TESTBRIDGE_TEST_RUNNER_FAIL_FAST)

Add GTEST_ALLOW_UNINSTANTIATED_PARAMTERIZED_TEST to mark a paramaterized test as allowed to be un-instantiated.
This allows test suites, that are defined in libraries and, for other reasons, get linked in (which should probably be avoided, but isn't always possible) to be marked as allowed to go uninstantiated.
This can also be used to grandfather existing issues and expedite adoption of the checks with regards to new cases before they can be fixed.

Add option (default to disabled) to make C++ type parameterized tests (TYPED_TEST_P) fail when they're not instantiated.
When an un-instantiated TYPED_TEST_P is found, a new test will be inserted that emits a suitable message. For now, that is just a notice, but the hope it to flip the bit to make it fail by default.

This reverts commit 20b5b8ecc7.
Reason for revert: Breaks existing applications, such as ANGLE
(angleproject.org), requires adding an extra prefix that needs to be
typed for no reason (when testing from command line) and increases the
logs' sizes by a non-trivial amount due to the very large number of
tests ANGLE runs.
Original commit message:
Add a compile time check to ensure that the parameters to TEST_P and
INSTANTIATE_TEST_SUITE_P are not empty. Some compilers already fail
in that case and, even where it works, it's likely to result in
technically invalid code by virtue of creating reserved identifiers:
https://en.cppreference.com/w/cpp/language/identifiers
First, every project is perfectly capable of adding a prefix if they
want to support such a compiler. This change penalizes every
project.
Second, using a prefix such as `_p` also results in reserved
identifiers, so this change is not really solving the problem. For that
matter, instead of generating `gtest_##prefix##...`, you can generate
`gtest_x##prefix##...` to correctly fix the issue, including when empty
prefixes are used.
This reverts commit 4c25e2b87f.
Reason for revert: Reverting the commit that disallows empty prefixes.
Original commit message:
Remove a test case rendered obsolete by disallowing empty argument for INSTANTIATE_TEST_SUITE_P.
Remove the code that it was testing.
Detect when C++ parametric tests (TEST_P) are not instantiated.
When an un-instantiated TEST_P is found, a new test will be inserted that will emit a warning message.
This can be made to error with minor code edits.
In the future, that is intended to be the default.

Change googletest to notice failures during SetUpTestSuite() and TearDownTestSuite().
Previously, errors that occurred during those functions were logged but otherwise ignored. After this change, such failures will cause the test to fail and a brief summary will be printed at the bottom of the test log.

Previously, skip messages were invisible, so debugging skips was hard.
Now we have this:

Mark more functions with "override" keyword, just like
it was done in commit 2460f97152.
This should prevent compiler from complaining while compiling both
user code, and the googletest code itself with the -Wsuggest-override
option turned on; with the exception of:
* calls to new MOCK_METHOD() in test/gmock-function-mocker_test.cc
* calls to old MOCK_METHODx()/MOCK_CONST_METHODx() in other
unit test files.
Closes#2493
- Fix a bug in dealing with paramaterized tests where the name is it self a macro expansion.
- Add a compile time check to ensure that the parameters to TEST_P and INSTANTIATE_TEST_SUITE_P are not empty. The above fix causes some compilers to fail in that case and even where it works, it's likely to result in technically invalid code by virtue of creating reserved identifiers:

gtest prior to this change would completely ignore `GTEST_SKIP()` if
called in `Environment::SetUp()`, instead of bailing out early, unlike
`Test::SetUp()`, which would cause the tests themselves to be skipped.
The only way (prior to this change) to skip the tests would be to
trigger a fatal error via `GTEST_FAIL()`.
Desirable behavior, in this case, when dealing with
`Environment::SetUp()` is to check for prerequisites on a system
(example, kernel supports a particular featureset, e.g., capsicum), and
skip the tests. The alternatives prior to this change would be
undesirable:
- Failing sends the wrong message to the test user, as the result of the
tests is indeterminate, not failed.
- Having to add per-test class abstractions that override `SetUp()` to
test for the capsicum feature set, then skip all of the tests in their
respective SetUp fixtures, would be a lot of human and computational
work; checking for the feature would need to be done for all of the
tests, instead of once for all of the tests.
For those reasons, making `Environment::SetUp()` handle `GTEST_SKIP()`,
by not executing the testcases, is the most desirable solution.
In order to properly diagnose what happened when running the tests if
they are skipped, print out the diagnostics in an ad hoc manner.
Update the documentation to note this change and integrate a new test,
gtest_skip_in_environment_setup_test, into the test suite.
This change addresses #2189.

Fix emission of -Wzero-as-null-pointer-constant when comparing integers.
The following code fails to compile:
#pragma clang diagnostic error "-Wzero-as-null-pointer-constant"
void foo() {
EXPECT_EQ(0, 0);
}
This happens because gtest checks the first argument to EXPECT_EQ and
ASSERT_EQ is a null pointer constant. The magic it does to do this causes the
warning to be emitted.
This patch removes that check. It replaces the explicit check with a Compare
overload that can only be selected when 0 or nullptr is passed on the LHS
with a pointer on the right.
This patch does not suppress -Wzero-as-null-pointer-constant when users
are actually using it as NULL.

Due to some caveats in the FreeBSD build system and the fact that the
source file is used to compile 2 different death tests with different
flags, I needed (as a shortterm workaround) to copy the test to 2
differently named files.
While this works for compiling the test, as I discovered, this doesn't
work with running `CxxExceptionDeathTest.PrintsMessageForStdException`,
as the testcase hardcodes `googletest-death-test_ex_test.cc`. Use `__FILE__`
when looking for failures, as opposed to looking for the hardcoded name
as it can vary depending on how the test was built.
