Stack traces in assertion failures are an extremely useful tool for
developers tasked with investigating failing tests. It's difficult to
understate this. In contrast to ordinary test assertions (e.g.,
ASSERT_TRUE or EXPECT_FALSE), SUCCEED() is a developer-authored
directive that indicates a success codepath. In fact, the documentation
states that this directive doesn't generate any output. Generating stack
traces for uses of SUCCEED() is wasted work since they are never
printed. If this were to change one day in the future, they still would
not be useful since any emitted message would include the file and line
number where SUCCEED was used. In addition to being noise in the output
in this case, symbolization of stack traces is not free. In some
Chromium configurations, symbolization for use of SUCCEED() can incur a
cost in excess of 25 seconds for a test that otherwise takes 0-1ms; see
https://crbug.com/1517343.
In this CL, we suppress generation and emission of stack traces for
kSuccess messages to reduce the overhead of SUCCEED().

https://bazel.build/external/overview#bzlmod
Bzlmod will be the default in a future Bazel release.
By default it requires projects to be registered with the
Bazel Central Registry (https://registry.bazel.build/) and
thus uses regular releases by default.
Users that want to "live-at-head" can still do this through
with overrides (https://bazel.build/external/module#overrides).
This change updates GoogleTest dependencies to use released versions.
CI uses Bzlmod except in the case of linux_gcc-floor, which will
keep testing the old WORKSPACE-based dependency system.

When -Wdouble-promotion is enabled, the templatized function AppropriateResolution fails to compile since its float instantiation promotes floats to doubles when doing arithmetic and comparisons. Add static casts to resolve these errors.

This enables automatic color output without filesystem support, as that only requires testing to see if the output is a terminal.

Stack traces in assertion failures are an extremely useful tool for
developers tasked with investigating failing tests. It's difficult to
understate this. In contrast to ordinary test assertions (e.g.,
ASSERT_TRUE or EXPECT_FALSE), GTEST_SKIP is a developer-authored
directive to skip one or more tests. Stack traces emitted in skip
messages do not give the developer useful information, as the skip
message itself contains the code location where GTEST_SKIP was used. In
addition to being noise in the output, symbolization of stack traces is
not free. In some Chromium configurations, symbolization in a skipped
test can incur a cost in excess of 25 seconds for a test that otherwise
takes 0-1ms; see https://crbug.com/1517343#c9.
In this CL, we suppress generation and emission of stack traces for
kSkip messages to reduce the output noise and overhead of GTEST_SKIP().

TSAN identified a data race between updates to the states_ map (ex. in Mock::UnregisterLocked) and the iteration done in this destructor. Writes to the map use g_gmock_mutex, but the destructor does not acquire it. Acquiring the lock here fixes the data race.
It should only be possible to trigger this TSAN finding in cases where a mock object is deleted by a thread other than the main thread.

We avoid overloading or specializing `testing::Throw` as this is fundamentally a different operation than throwing the object.
However, we disable the corresponding overload of `testing::Throw` to prevent likely mistakes in the usage.

gmock.h is the umbrella header to be used for rest of the library, and it also
enables users to export certain details. This wasn't working for some interfaces
like EXPECT_CALL because gmock-spec-builders wasn't explicitly exported.

defined in csignal, leading to a compilation failure on at least
OpenBSD/sparc64 with gcc 8.

This is a somewhat recent change for Android (I'm not clear on whether it's a recent change for NetBSD, or if Android was just very behind on its implementation), so while this worked fine as recently as API 32 devices, REG_GNU is required for API 34 (API 33 untested).
A test actually caught this, but https://github.com/google/googletest/pull/4334 "fixed" the test rather than the implementation. This CL also reverts the test change so it can catch the failure.

The requirement is vaguely documented by "Only the return value of the last action in the sequence will be used.".
However, this can be misleading, as users could potentially expect default-constructed values to be returned in absence of a matching return type.

Template type int changed to size_t.
This fixes compile warning `conversion to ‘long unsigned int’ from ‘int’ may change the sign of the result` in gmock-function-mocker.h.
* These long-dead variants of the proto matchers don't exist in the current version of Googletest.
* No evidence of external usage: [the only external references I see](https://www.google.com/search?q=%22protocolmessageequals%22+OR+%22protocolmessageequals%22) are copies of this guide. Possibly they were already removed by the time Googletest was publicly released.

The `Mutex` is locked with the `MutexLock` before spawning the thread, so that the thread is prevented from completing (by being blocked on `Mutex`) before the new thread count is obtained. However, the existing bug (introduced in 22e6055) releases `Mutex` before obtaining the new thread count, which allows the thread to run to completion in the meantime.
Also, since the `(thread_count_after_create != starting_count + 1)` condition (line 328) skips the remainder of the `for`-loop body on every iteration, `thread_count_after_join` stays uninitialized.
