99ecfd3b52 apple: Convert GN libs lists to frameworks.
GN recently added support for Apple frameworks to link, rather than
overloading the libs lists. This pulls .frameworks out of the libs
lists, so that GN can stop supporting .frameworks in libs in the
future.

a45eea40fc Update gtest to e3f0319d89f4cbf32993de595d984183b1a9fc57
I’m most interested in picking up 1b3eb6ef3462, “Explicitly define copy
constructors used in googletest tests.”

This also reorganizes files and rewrites text to refer to this project
as Google Test and googletest (and Google Mock and googlemock), as it
prefers to be known. Some filenames are left at gtest_* following the
precedent set by gtest itself. For example, #include "gtest/gtest.h" is
still used, so #include "test/gtest_death.h" is retained too.
gtest_all_test OutputFileHelpersTest.GetCurrentExecutableName hard-codes
the expected executable name as gtest_all_test among other options that
do not include googletest_all_test, so test executables retain their
names as well.

adfd94a357 ios: Use compat to provide items missing from the iOS SDK
This updates the way that the .defs files added in 1bfd7d06ed60 are
treated, by putting them in compat/ios, using compat as intended. The
.defs files in compat forward, via #include, to the ones in
third_party/xnu. Additionally, compat/mac is enabled for iOS, as
everything in compat/mac is sensible on iOS, and will have no effect
when rendered unnecessary by the iOS SDK.

This also changes util:mig_output to a static_library instead of a
source_set. I don’t think there was any reason for it to have been a
source_set to begin with. static_library is preferred for nearly
everything.

64b8791f45 ios: Build util/mach/exc_server_variants.cc, support code, and tests
This makes UniversalMachExcServer available on iOS.
UniversalMachExcServer is the foundation for a Mach exc and mach_exc
server.

Some code in UniversalMachExcServer needs to be evaluated to ensure that
portions that run in the same process that has sustained the exception
are safe to do so at that time. For example,
SimplifiedExcServer<ExcTraits>::Interface instantiates and appends to a
std::vector<>, which is generally unsafe in this context. However, that
code responds to exc requests. The mach_exc equivalent,
SimplifiedMachExcServer<MachExcTraits>::Interface, does not use a vector
at all.

This also enables support code in the form of CompositeMachMessageServer
and UniversalExceptionRaise, all of the tests for
CompositeMachMessageServer, and most of the test for
exc_server_variants.cc. The multiprocess-based exc_server_variants tests
remain disabled on iOS.

1bfd7d06ed ios: Run mig with the correct SDK and architecture
mig was being invoked without any -arch argument, causing it to assume
the build system’s native architecture, which would be x86_64. This is
not correct for iOS device builds, which use arm64. The -arch argument
must be plumbed to mig for correct behavior.

When building for iOS, mig was being invoked without any -isysroot
argument, causing it to use the root for the build system, which runs
macOS and not iOS. The macOS SDK doesn’t include the ARM definitions
needed for iOS device builds.

<mach/exc.defs> and <mach/mach_exc.defs> depend on a small number of
other .defs files to provide definitions of standard types. All .defs
files are absent from the iOS SDK. These .defs files are borrowed from
xnu and placed in third_party/xnu. An additional --include argument is
added to allow mig to locate these files.

3e748e9c4e ios: Provide a copy of mach_exc.defs and run mig on it
This updates (and corrects) 8dbbaff2e1a5, which added exc.defs, by
adding mach_exc.defs too.

The difference betwen the exc and mach_exc subsystems is that the |code|
parameter is int[] in exc and int64_t[] in mach_exc. Many exceptions
carry the exception address in code[1], and a 32-bit int results in the
exception address being truncated in exc. No information is lost in
mach_exc, where a 64-bit int64_t is used.

In 8dbbaff2e1a5, I misremembered the type of the |code| parameter as a
type derived from uintptr_t, such as vm_address_t, an integer as wide as
a pointer. I was wrong, and mach_exc is necessary. I also noted that
Apple normally forbids mach_-prefixed interfaces in favor of the
prefix-less ones for the reasons I mentioned, and that, all else being
equal, it was desirable to adhere to the spirit of that convention.
Because neither exc nor mach_exc are available in the SDK, it’s moot
from a technical perspective, as we need to provide our own stubs either
way.

4cb79941fc ios: Build four more Mach message and exception utilities
This enables the following code in util/mach on iOS:
 - exception_behaviors.{cc,h}
 - exception_ports.{cc,h}
 - mach_message.{cc,h}
 - mach_message_server.{cc,h}

Only the ExceptionBehaviors and MachMessage tests are built, because the
other two are tested by multiprocess tests that won’t run on iOS.

The AuditPIDFromMachMessageTrailer function from mach_message.h is
excluded on iOS because it relies on <bsm/libbsm.h>, which is broken on
iOS: it depends on <bsm/audit_record.h>, which is missing from the SDK.
Additionally, the BSM function that Crashpad uses, audit_token_to_au32,
is marked as unavailable on iOS. Crashpad uses it on macOS to
authenticate Mach messages sent by other processes, but this is moot on
iOS.

8dbbaff2e1 ios: Provide a copy of exc.defs and run mig on it to generate exc stubs
The iOS SDK doesn’t include a copy of <mach/exc.defs>. It only provides
<mach/exc.h>, which is just the user-side header. To obtain declarations
and implementations of the server-side stubs, a current copy of
<mach/exc.defs> is added to third_party, and the mig action in util is
updated to use it on iOS.

The three other mig subsystems that Crashpad uses are not brought to
iOS:
 - mach_exc is identical to exc except it always uses 64-bit quantities
   for addresses in place of exc’s use of quantiies sized for native
   pointers. Because all iOS work is limited to a single process, there
   is no need to consider cross-process operation with variable bitness,
   so mach_exc is unnecessary. We’re also only targeting 64-bit for iOS,
   so exc will always suffice. This follows the spirit of other
   mach_-prefixed routines on iOS, where Apple forbids mach_vm_read to
   user applications but permits vm_read.
 - notify is primarily used on macOS in the Crashpad handler process to
   receive a no-senders notification, which is used to trigger handler
   shutdown when it has no more clients. This is not believed to be
   useful to Crashpad on iOS, which is restricted to single-process
   operation.
 - child_port is a Crashpad-specific subsystem used to pass Mach rights
   between processes, but is similarly useless when restricted to
   single-process operation as on iOS.

b2fd7d5307 [ios] Bring up first half of UncaughtExceptionHandler.
When code raises an Objective-C exception, unwind the stack looking for
any exception handlers. If an exception handler is encountered, test to
see if it is a function known to be a catch-and-rethrow 'sinkhole'
exception handler. Various routines in UIKit and elsewhere do this, and
they obscure the exception stack, since the original throw location is
no longer present on the stack (just the re-throw) when Crashpad
captures the crash report. In the case of sinkholes, trigger an
immediate exception to capture the original stack.

The is an improvement over the alternative,
NSSetUncaughtExceptionHandler, which passes along the stack frames, but
not the stack memory contents and full exception context itself.

The details of what happens after a fatal exception is triggered are
unresolved in this CL.  For now, simply call std::terminate.

This code was inspired by chromium/src/chrome/browser/mac/
exception_processor.mm.

c4cc4e6ac9 android: initialize signal dispositions
Bionic installs signal handlers which request crash
dumps from Android's debuggerd, but there are errors
in how signals which aren't automatically re-raised
are handled on Marshmallow (API 23).

Before requesting a dump, Bionic acquires a lock to
communicate with debuggerd and expecting imminent
death, never releases it.

While handling the dump request, debuggerd allows
the dying process to continue before
ptrace-detaching it. So, when Bionic manually
re-raises a signal, it is intercepted by debuggerd
and the dying process is allowed to live.

Bionic restores SIG_DFL for the signal it's just
handled, but if a different crash signal is later
recieved, Bionic attempts to reacquire the lock to
communicate with debuggerd and blocks forever.

Disable Bionic's signal handlers for these signals
on Marshmallow.

359fc4a133 [Windows] Add checks for DLL loader lock.
This CL adds code to check if the current thread holds the DLL loader
lock. This code can be used to enforce the requirement that certain
parts of crashpad, such as process creation are not done during calls
to DllMain which can lead to deadlocks and crashes. Only one check is
current enforced, in client process creation, and only in debug builds.

6dadd492b8 linux: fix proc stat reader flakiness
ProcStatReader.Threads is flaky because it relies on an internal,
imprecise measurement of boot time. The flaky test asserts that a
thread started after the main thread should have a start time >= the
main thread. The start time is returned in a timeval, with microsecond
precision, but the measurement of boot time requires two system calls
and the time between those system calls can be approximately a
microsecond. An unlucky event such as a change in system time could
make this imprecision arbitrarily bad.

This patch lets the caller of ProcStatReader.StartTime() inject the
boot time, allowing ProcStatReader to guarantee that threads have
correctly ordered time, given the same input boot time.

79b59b0a8f Add support for capture CPU context on Windows on ARM64
Most Crashpad builds use Microsoft's armasm64.exe macro assembler
for .asm source files. When building in Chromium, clang-cl is used
as the assembler instead. Since the two assemblers recognize different
assembly dialects, the same .asm file can't be used for each.
As a workaround, use a prebuilt .obj file when the Microsoft-dialect
assembler isn't available.

The obj file is generated from the capture_context_win_arm64.asm
by armasm64 macro assembler. If this asm file is modified,
the obj file needs to be updated.

d98690a182 android: enable upload
This patch also updates WorkerThread to execute DoWork() when
DoWorkNow() has been called, which is relevant when DoWorkNow() and
Stop() have both been called. This occurs regularly on Android where
the handler's current normal mode is to dump a single process and exit.
This change ensures the upload thread has a chance to upload the report
before the handler exits.

This change should not affect upload on Chrome/WebView/Chromecast which
don't pass Crashpad a --url option and are still responsible for their
own uploads.

a11243e8f1 linux: add wrappers for send/recvmsg
sendmsg() and recvmsg() are complicated to use. Refactor their usage
into functions with a simpler, tested interface and use those instead.
This also adds CreateCredentialSocketpair() to create a pair of
connected sockets with SO_PASSCRED set. This option should be set
before the possibility of any calls to sendmsg() with the socket pair
to avoid race conditions in properly setting credentials.

Also update the handler to use Strategy::kNoPtrace (which causes the
crash dump to fail without breaking the socket connection) if the
credentials were invalid, which can happen if SO_PASSCRED was set after
the call to sendmsg() or if the sending process does not exist in this
namespace.

59cdfbb031 linux: support multi client sockets in ExceptionHandlerServer
Multi client socket connections allow multiple clients to request crash
dumps from a handler process using a single, shared socket connection.

This connection mode does not support using a broker process which
requires a dedicated socket connection to ensure handler messages
aren't intercepted by the wrong clients.

The handler uses SIGCONT to indicate to the crasher when a crash dump
is complete (or has failed) and may continue.

8b2ec2aae4 Make TaskMemory a child class of ProcessMemory
Currently TaskMemory re-implements a number of Read* routines that are
implemented in a platform-independent way in ProcessMemory with access
to a single platform-specific ReadUpTo method. Implement the ReadUpTo
method for TaskMemory and subclass it from ProcessMemory to inherit the
remaining methods.

The ProcessMemoryTests didn't work on macOS because MultiprocessExec
can not access the child process' task port without root privileges or
the task_for_pid entitlement. Create an adaptor class for those tests to
use MachMultiprocess so that the child process sends its task port to
the parent.
