In my ongoing quest to break the Fuchsia tree in as many ways as
possible...
All binaries found in /system/test are automatically run. So when
http_transport_test_server and
crashpad_test_test_multiprocess_exec_test_child are unexpectedly run
they just hang, breaking the overall test run. To avoid this, package
them into a subdirectory which is the preferred solution.

Packaged test running seems to be a ways off, but with a bit of path
fiddling in test_paths.cc we can actually use the paths where the tests
are copied, so do that instead to get all the tests re-enabled. The
setup in BUILD.gn should be mostly-useful once packaging is working as
all helper/data files will need to specified there anyway.
Also, attempted fix to flaky behaviour in
ProcessReaderFuchsia.ChildThreads exposed because the tests are now
being run. zx_object_wait_many() waits on *any* of the objects, not
*all* of them. Derp!
And finally, for the same test, work around some unintuitive behaviour
in zx_task_suspend(), in particular that the thread will not be
suspended for the purpose of reading registers right away, but instead
only "sometime later", which appears in pratice to be after the next
context switch. Have ScopedTaskSuspend block for a while to try to
ensure the registers become readble, and if they don't, at least fail
noisily at that point.

The package deployment/running is in flux at the moment. In order to get
all the other tests on to the main Fuchsia waterfall, disable the ~25
tests that require external files (for launching child processes,
loading modules, or data files) because those operations all fail on
Fuchsia-without-packages right now. Upstream this is PKG-46. Once test
packaging and running has been resolved, this can be reverted.
These tests are still run when building Crashpad standalone on Fuchsia
as the standalone build simply copies all the relevant data files to the
device in /tmp.

In doing standalone bringup of Crashpad targeting Fuchsia, it seemed
tidy to keep the same literal paths to the dependencies that Chromium
needed and add stubs/forwarding to build/secondary in the Crashpad tree
as required to make those work.
However, when trying to build Crashpad in the Fuchsia tree itself, that
would require adding forwarding files to the Fuchsia tree to match the
Chromium directory structure, which would be awkward. Instead, have
explicit dependencies in the Crashpad tree that select the locations
for various dependencies.

This dependency was created in 107fb7631788 for macOS, but it’s not used
on other platforms. Since the test support library is broadly used to
test all of Crashpad, it’s useful even during early-stage porting. The
snapshot library is a higher-level module that builds upon other
components, and is not likely to be functional until the later stages of
porting. Expressing this dependency artifically makes it difficult to
test ports in development.

When I redid the Crashpad GN build a few weeks ago

tried to order things according to the GN style guide
(https://chromium.googlesource.com/chromium/src/tools/gn/+/HEAD/docs/style_guide.md).
As for conditionals, I tried to stick to doing a set of conditionals
after “sources” for just “sources”, and then another one at the bottom
for everything else.
It turns out that this was a good idea because it’s an error to say
“deps += [something]” inside a conditional until you’ve already said
“deps = [something_else]” first. (Maybe that’s why I did it.)

These are no-ops in standalone builds, but add functionality when

These stub files are all contained in a secondary source root in

Crashpad has many tests that crash intentionally. Some of these are
gtest death tests, and others arrange for intentional crashes to test
Crashpad’s own crash-catching logic. On macOS, all of the gtest death
tests and some of the other intentional crashes were being logged by
ReportCrash, the system’s crash reporter. Since these reports
corresponded to intentional crashes, they were never useful, and served
only to clutter ~/Library/Logs/DiagnosticReports.
Since Crashpad is adept at handling exceptions on its own, this
introduces the “exception swallowing server”,
crashpad_exception_swallower, which is a Mach exception server that
implements a no-op exception handler routine for all exceptions
received. The exception swallowing server is established as the task

Unreferenced, and not working at all in Crashpad-standalone.
Copied from Chromium at 52a9831d81f2099ef9f50fcdaca5853019262c35 to have
a point where a roll back into Chromium should be a no-op (with Chromium's

I'm not sure what we want to do about the various gni references into
Chromium (e.g. //build/config/sanitizers/sanitizers.gni, //testing/test.gni,

the sooner we can figure out the sort of knobs and dials we need.

When this test examines a module that doesn’t have a CodeView PDB link,
it will fail. Such a link may be missing when linking with Lexan
ld-link.exe without /DEBUG. The test had been examining the executable
as its module. Since it’s easier to provide a single small module linked
with /DEBUG than it is to require that the test executable always be
linked with /DEBUG, the test is revised to always load a module and
operate on it. The module used is the existing
crashpad_snapshot_test_image_reader_module.dll. It was chosen because
it’s also used by PEImageReader.DebugDirectory, which also requires a
CodeView PDB link.
It’s the build system’s responsibility to ensure that
crashpad_snapshot_test_image_reader_module.dll is linked appropriately.
Crashpad’s own GYP-based build always links with /DEBUG. Chrome’s
GN-based Crashpad build will require additional attention at
symbol_level = 0.

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.

As of

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.

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,

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

gtest used to require (expected, actual) ordering for arguments to

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,

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.

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.

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

- In multiprocess_exec_test_child, use getrlimit(RLIMIT_NOFILE) instead
of max(sysconf(_SC_OPEN_MAX), OPEN_MAX, getdtablesize()). OPEN_MAX is
not availble on Linux (but is in Android as a bogus value), and
getdtablesize() is not available in Android since 5.0.0 (API 21).
sysconf(_SC_OPEN_MAX) and getdtablesize() both return
getrlimit(RLIMIT_NOFILE) on all relevant platforms.
- Add a Linux/Android implementation of test::Paths::Executable().
- Respect TMPDIR for all POSIX platforms in
ScopedTempDir::CreateTemporaryDirectory(). If TMPDIR is unset or
empty, use /tmp, except on Android, where /tmp does not exist and
/data/local/tmp is used instead.
Also:
- Fix the Mac and Windows implementations of test::Paths::Executable()
to abort on fatal error, in line with the new Linux/Android version.

Previously, StartHandler() launched the handler process, then connected
over a pipe to register for crash handling. Instead, the initial client
can create and inherit handles to the handler and pass those handle
values and other data (addresses, etc.) on the command line.
This should improve startup time as there's no need to synchronize with
the process at startup, and allows avoiding a call to CreateProcess()
directly in StartHandler(), which is important for registration for
crash reporting from DllMain().
Incidentally adds new utility functions for string/number conversion and
string splitting.
Note: API change; UseHandler() is removed for all platforms.

_NSGetExecutablePath() returns a buffer size including space for the
trailing NUL byte. A std::string’s length should be one less than this,
because the std::string’s length does not include the trailing NUL byte
that is guaranteed to be present.

This was done in Chromium’s local copy of Crashpad in 562827afb599. This
change is similar to that one, except more care was taken to avoid
including headers from a .cc or _test.cc when already included by the
associated .h. Rather than using <stddef.h> for size_t, Crashpad has
always used <sys/types.h>, so that’s used here as well.
This updates mini_chromium to 8a2363f486e3a0dc562a68884832d06d28d38dcc,
which removes base/basictypes.h.

This more-natural spelling doesn’t require Crashpad developers to have
to remember anything special when writing code in Crashpad. It’s easier
to grep for and it’s easier to remove the “compat” part when pre-C++11
libraries are no longer relevant.

This unifies several things that used a 16-character random string, and
a few other users of random identifiers where it also made sense to use

In https://codereview.chromium.org/1411523006, the Mach port scopers are
becoming better ScopedGenerics and are losing the type conversion
operators in the process. This is needed to adapt to that change. get()
is ugly, but being explicit about conversion isn’t a bad thing, and
these scopers will gain functionality such as Pass() as part of the
switch.
As a bonus, some would-be uses of get() to check for valid port rights
are becoming a more descriptive is_valid().

This wraps bootstrap_check_in() in BootstrapCheckIn(), and
bootstrap_look_up() in BootstrapLookUp(). The wrappers make it more
difficult to accidentally leak a returned right. They’re easier to use,
encapsulating common error checking and logging, simplifying all call
sites.
