There is never any possibility to run 32-bit processes on macOS on

This transforms ProcessReaderMac::Is64Bit into a compile-time constant
“yes” when building for a system that will never see a 32-bit process.
This is a lightweight way to get much 32-bit support code removed from
optimized compiled output, including all of process_types. In an
optimized build of crashpad_handler for arm64, this is a 3% reduction
from 569kB to 552kB (-17kB).

cl_kernels modules have appeared since OS X 10.10 as MH_BUNDLE modules
with a __TEXT segment, one section of which claims to belong to the __LD
segment. They are produced when OpenCL is asked to compile an OpenCL
kernel for the CPU, but this currently appears impossible on arm64.
The workaround is omitted as it appears to be unnecessary, but the test
still attempts to create an OpenCL kernel for the CPU. If this ever
becomes possible, and the modules are malformed, the test will fail as
an indication that the workaround must be reinstated for arm64.

The macOS 11.0 SDK, as of Xcode 12b6 12A8189n, has not updated
<AvailabilityMacros.h> with a MAC_OS_X_VERSION_11_0 or
MAC_OS_X_VERSION_10_16 constant. However, the <Availability.h> interface
has been updated to provide both __MAC_11_0 and __MAC_10_16.
<AvailabilityMacros.h>’s MAC_OS_X_VERSION_MAX_ALLOWED, which is supposed
to identify the SDK version, is broken in the 11.0 SDK in that whenever
the deployment target is set to 10.15 or earlier, the SDK will be
mis-identified through this interface as 10.15. When using the
<Availability.h> equivalent, __MAC_OS_X_VERSION_MAX_ALLOWED, the 11.0
SDK is identified as 10.16 (arguably it should be internally versioned
as 11.0, but at least this interface allows it to be detected
unambiguously.) It’s clear that the <AvailabilityMacros.h> interface
provides no meaningful support for the macOS 11.0 SDK at all, but
<Availability.h> does.
<Availability.h> was introduced in the Mac OS X 10.5 SDK, so there is no
relevant SDK version compatibility problem with this interface.
Key differences between these interfaces for the purposes used by
Crashpad:
- <AvailabilityMacros.h> → <Availability.h>
- MAC_OS_X_VERSION_MIN_REQUIRED (DT) → __MAC_OS_X_VERSION_MIN_REQUIRED
- MAC_OS_X_VERSION_MAX_ALLOWED (SDK) → __MAC_OS_X_VERSION_MAX_ALLOWED
- MAC_OS_X_VERSION_x_y → __MAC_x_y
- <Availability.h> __MAC_OS_X_VERSION_* SDK/DT macros are only
available when targeting macOS, while <AvailabilityMacros.h>
MAC_OS_X_VERSION_* SDK/DT macros are available on all Apple platforms,
which may be a source of confusion. (<Availability.h> __MAC_* macros
do remain available on all Apple platforms.)
This change was made mostly mechanically by:
sed -i '' -Ee 's/<AvailabilityMacros.h>/<Availability.h>/g' \
$(git grep -E -l '<AvailabilityMacros.h>' |

sed -i '' -Ee 's/(MAC_OS_X_VERSION_(MIN_REQUIRED|MAX_ALLOWED))/__\1/g' \

Causes MinidumpMemoryListWriter to merge all overlapping ranges before
writing the MINIDUMP_MEMORY_LIST. This is:
1) Necessary for the Google internal crash processor, which in some
cases attempts to read the raw memory (displaying ASAN red zones),
and aborts if there are any overlapping ranges in the minidump on
load;
2) Necessary for new-ish versions of windbg (see bug 216 below). It is
believed that this is a change in behavior in the tool that made
dumps with overlapping ranges unreadable;
3) More efficient. The .dmp for crashy_program goes from 306K to 140K
with this enabled. In Chrome minidumps where
set_gather_indirectly_referenced_memory() is used (in practice this
means Chrome Windows Beta, Dev, and Canary), the savings are expected
to be substantial.

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
handler for EXC_CRASH and EXC_CORPSE_NOTIFY exceptions during gtest
death tests invoked by {ASSERT,EXPECT}_DEATH_{CHECK,CRASH}, and for all
child processes invoked by the Multiprocess test infrastructure. The
exception swallowing server is not in effect at other times, so
unexpected crashes in test code can still be handled by ReportCrash or
another crash reporter.
With this change in place, no new reports are generated in the
user-level ~/Library/Logs/DiagnosticReports or the system’s
/Library/Logs/DiagnosticReports during a run of Crashpad’s full test
suite on macOS.

The handler will now be less strict about checking CrashpadInfo struct
sizes. Assuming the signature and version fields match:
- If the handler sees a struct smaller than it’s expecting, the module
was likely built with an earlier version of the client library, and
it’s safe to treat the unknown fields as though they were zero or
other suitable default values.
- If the handler sees a struct larger than it’s expecting, the module
was likely built with a later version of the client library. In that
case, actions desired by the client will not be performed, but this
is not otherwise an error condition.
The CrashpadInfo struct must always be at least large enough to contain
at least the size field. The signature and version fields are always
checked.
The section size must be at least as large as the size carried within
the struct. To account for possible section padding, strict equality is
not required.

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.
