c009b85449 Use GTEST_SKIP() instead of custom DISABLED_TEST()
Since gtest 00938b2b228f, gtest has built-in first-class support for
skipping tests, which is functionally identical (at least in Crashpad’s
usage) to the home-grown support for run-time dynamically disabled tests
introduced in Crashpad 5e9ed4cb9f69.

Use the new standard pattern, and remove all vestiges of the custom
local one.

This was done previously in 79f4a3970a64, but was reverted in
bba9d0819c12 because Chromium’s test launcher did not support
GTEST_SKIP() at the time. The deficiency is on file as
https://crbug.com/912138.

While that bug was never specifically marked as “fixed” and I haven’t
found what changed in Chromium, I do now see some use of GTEST_SKIP() in
Chromium. I also prototyped this change in Chromium at
https://chromium-review.googlesource.com/c/1854691/ and found that
GTEST_SKIP() does indeed now appear to work.

1669ca2bac test: Rework TestPaths interface for obtaining 32-bit build artifacts
The design for running all Crashpad unit tests on Chromium’s try- and
buildbots involves pulling all tests into a single monolithic
crashpad_tests executable. Many Crashpad tests base the name of their
child executables or modules on the name of the main test executable.
Since the main test executable will have a different name in the
in-Chromium build, knowledge of the test executable name (referred to as
“module” here) needs to be added to the tests themselves.

This introduces TestPaths::BuildArtifact(), which allows the module name
to be specified. For Crashpad’s standalone build, the module name is
verified against the main test executable’s name.
TestPaths::BuildArtifact() can also locate paths in the alternate 32-bit
output directory for 64-bit Windows tests, taking on the responsibility
for what the new (5e9ed4cb9f69) TestPaths::Output32BitDirectory(), now
obsolete, did.

5e9ed4cb9f win: Dynamically disable WoW64 tests absent explicit 32-bit build output
Rather than having the 64-bit build assume that it lives in
out\{Debug,Release}_x64 and that it can find 32-bit build output in
out\{Debug,Release}, require the location of 32-bit build output to be
provided explicitly via the CRASHPAD_TEST_32_BIT_OUTPUT environment
variable. If this variable is not set, 64-bit tests that require 32-bit
test build output will dynamically disable themselves at runtime.

In order for this to work, a new DISABLED_TEST() macro is added to
support dynamically disabled tests. gtest does not have its own
first-class support for this
(https://groups.google.com/d/topic/googletestframework/Nwh3u7YFuN4,
https://github.com/google/googletest/issues/490) so this local solution
is used instead.

For tests via Crashpad’s own build\run_tests.py, which is how Crashpad’s
own buildbots and trybots invoke tests, CRASHPAD_TEST_32_BIT_OUTPUT is
set to a locaton compatible with the paths expected for the GYP-based
build. No test coverage is lost on Crashpad’s own buildbots and trybots.

For Crashpad tests in Chromium’s buildbots and trybots, this environment
variable will not be set, causing these tests to be dynamically
disabled.

4b450c8137 test: Use (actual, [un]expected) in gtest {ASSERT,EXPECT}_{EQ,NE}
gtest used to require (expected, actual) ordering for arguments to
EXPECT_EQ and ASSERT_EQ, and in failed test assertions would identify
each side as “expected” or “actual.” Tests in Crashpad adhered to this
traditional ordering. After a gtest change in February 2016, it is now
agnostic with respect to the order of these arguments.

This change mechanically updates all uses of these macros to (actual,
expected) by reversing them. This provides consistency with our use of
the logging CHECK_EQ and DCHECK_EQ macros, and makes for better
readability by ordinary native speakers. The rough (but working!)
conversion tool is
https://chromium-review.googlesource.com/c/466727/1/rewrite_expectassert_eq.py,
and “git cl format” cleaned up its output.

EXPECT_NE and ASSERT_NE never had a preferred ordering. gtest never made
a judgment that one side or the other needed to provide an “unexpected”
value. Consequently, some code used (unexpected, actual) while other
code used (actual, unexpected). For consistency with the new EXPECT_EQ
and ASSERT_EQ usage, as well as consistency with CHECK_NE and DCHECK_NE,
this change also updates these use sites to (actual, unexpected) where
one side can be called “unexpected” as, for example, std::string::npos
can be. Unfortunately, this portion was a manual conversion.

4688351623 “Promote” test::Paths::Executable() to Paths::Executable()
This supports the “double handler” or “double handler with low
probability” models from https://crashpad.chromium.org/bug/143.

For crashpad_handler to be become its own client, it needs access to its
own executable path to pass to CrashpadClient::StartHandler(). This was
formerly available in the test-only test::Paths::Executable(). Bring
that function’s implementation to the non-test Paths::Executable() in
util/misc, and rename test::Paths to test::TestPaths to avoid future
confusion.

test::TestPaths must still be used to access TestDataRoot(), which does
not make any sense to non-test code.

test::TestPaths::Executable() is retained for use by tests, which most
likely prefer the fatal semantics of that function. Paths::Executable()
is not fatal because for the purposes of implementing the double
handler, a failure to locate the executable path (which may happen on
some systems in deeply-nested directory hierarchies) shouldn’t cause the
initial crashpad_handler to abort, even if it does prevent a second
crashpad_handler from being started.

00b6442752 Make file_io reads more rational and predictable
ReadFile() attempted to continue reading after a short read. In most
cases, this is fine. However, ReadFile() would keep trying to fill a
partially-filled buffer until experiencing a 0-length read(), signaling
end-of-file. For certain weird file descriptors like terminal input, EOF
is an ephemeral condition, and attempting to read beyond EOF doesn’t
actually return 0 (EOF) provided that they remain open, it will block
waiting for more input. Consequently, ReadFile() and anything based on
ReadFile() had an undocumented and quirky interface, which was that any
short read that it returned (not an underlying short read) actually
indicated EOF.

This facet of ReadFile() was unexpected, so it’s being removed. The new
behavior is that ReadFile() will return an underlying short read. The
behavior of FileReaderInterface::Read() is updated in accordance with
this change.

Upon experiencing a short read, the caller can determine the best
action. Most callers were already prepared for this behavior. Outside of
util/file, only crashpad_database_util properly implemented EOF
detection according to previous semantics, and adapting it to new
semantics is trivial.

Callers who require an exact-length read can use the new
ReadFileExactly(), or the newly renamed LoggingReadFileExactly() or
CheckedReadFileExactly(). These functions will retry following a short
read. The renamed functions were previously called LoggingReadFile() and
CheckedReadFile(), but those names implied that they were simply
wrapping ReadFile(), which is not the case. They wrapped ReadFile() and
further, insisted on a full read. Since ReadFile()’s semantics are now
changing but these functions’ are not, they’re now even more distinct
from ReadFile(), and must be renamed to avoid confusion.

ab01df1ffe win: Adjust thread suspend count for DumpAndCrashTargetProcess() case
Because DumpAndCrashTargetProcess() suspends the process, the thread
suspend count is one too high for all threads other than the injection
one in the thread snapshots. Compensate for this when we detect this
