As of
00a0654929,
crashpad_util_test is able to run in Chromium. It uses Chromium’s own
base::TestLauncher rather than gtest’s RUN_ALL_TESTS() for proper
integration with Swarming.
Launching WinMultiprocess test children out of the same test executable
via WinChildProcess is not compatible with Chromium’s parallel, shardy,
Swarmy test launcher. When running these children, the standard gtest
RUN_ALL_TESTS() launcher will now be used, even in Chromium.
Two tests disabled in Chromium are now enabled:
ExceptionHandlerServerTest.MultipleConnections and
ScopedProcessSuspend.ScopedProcessSuspend.
As part of this work, I discovered that disabled tests chosen to run via
--gtest_also_run_disabled_tests did not actually work for
WinMultiprocess-based tests, because gtest’s test launcher would refuse
to run the child side of the test, believing it was disabled. This is
fixed by always supplying --gtest_also_run_disabled_tests to
WinChildProcess children, on the basis that if the parent is managing to
run and it’s disabled, disabled tests must actually be enabled.

This upstreams part of
00a0654929.
The gmock_main and gtest_main test launchers detect via a
CRASHPAD_IN_CHROMIUM macro that they are building as part of Chromium,
and use Chromium’s custom test launcher rather than gtest’s
RUN_ALL_TESTS(). This enables parallelism, sharding, and integration
with Swarming.
WinMultiprocess-based tests are not compatible with this test launcher
or with the Swarming test design, and must be disabled when
CRASHPAD_IN_CHROMIUM is set. This is covered by
https://crashpad.chromium.org/bug/205.
CRASHPAD_IN_CHROMIUM is never defined during Crashpad’s own standalone
build, it’s only defined when building in Chromium.

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.

This uses “static” at function scope to avoid making local copies, even
in cases where the compiler can’t see that the local copy is
unnecessary. “constexpr” adds additional safety in that it prevents
global state from being initialized from any runtime dependencies, which
would be undesirable.
At namespace scope, “constexpr” is also used where appropriate.
For the most part, this was a mechanical transformation for things
matching '(^| )const [^=]*\['.
Similar transformations could be applied to non-arrays in some cases,
but there’s limited practical impact in most non-array cases relative to

_dyld_get_all_image_infos() was only used in test code in Crashpad.
This addresses two related problems.
When running on 10.13 or later, _dyld_get_all_image_infos() is not
available. It appears to still be implemented in dyld, but its symbol is
now private. This was always known to be an “internal” interface. When
it’s not available, fall back to obtaining the address of the process’
dyld_all_image_infos structure by calling task_info(…, TASK_DYLD_INFO,
…). Note that this is the same thing that the code being tested does,
although the tests are not rendered entirely pointless because the code
being tested consumes dyld_all_image_infos through its own
implementation of an out-of-process reader interface, while the
dyld_all_image_infos data obtained by _dyld_get_all_image_infos() is
handled strictly in-process by ordinary memory reads. This is covered by
bug 187.
When building with the 10.13 SDK, no _dyld_get_all_image_infos symbol is
available to link against. In this case, access the symbol strictly at
runtime via dlopen() if it may be available, or when expecting to only
run on 10.13 and later, don’t even bother looking for this symbol. This
is covered by part of bug 188.

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.

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.

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.

This makes Doxygen’s output more actionable by setting QUIET = YES to
suppress verbose progress spew, and WARN_IF_UNDOCUMENTED = NO to prevent
warnings for undocumented classes and members from being generated. The
latter is too noisy, producing 721 warnings in the current codebase.
The remaining warnings produced by Doxygen were useful and actionable.
They fell into two categories: abuses of Doxygen’s markup syntax, and
missing (or misspelled) parameter documentation. In a small number of
cases, pass-through parameters had intentionally been left undocumented.
In these cases, they are now given blank \param descriptions. This is
not optimal, but there doesn’t appear to be any other way to tell
Doxygen to allow a single parameter to be undocumented.
Some tricky Doxygen errors were resolved by asking it to not enter
directiores that we do not provide documentation in (such as the
“on-platform” compat directories, compat/mac and compat/win, as well as
compat/non_cxx11_lib) while allowing it to enter the
“off-platform” directories that we do document (compat/non_mac and
compat/non_win).
A Doxygen run (doc/support/generate_doxygen.sh) now produces no output
at all. It would produce warnings if any were triggered.
Not directly related, but still relevant to documentation,
doc/support/generate.sh is updated to remove temporary removals of
now-extinct files and directories. doc/appengine/README is updated so
that a consistent path to “goapp” is used throughout the file.
