475ac81cce win: Implement CRASHPAD_SIMULATE_CRASH()
Windows requires the connection to the handler to do anything, so it
can't really be implemented or tested without CrashpadClient and the
connection machinery.

d1d341c719 win: Fix always-rebuild of crashpad_snapshot_test_image_reader_module.dll
Ninja assumes all DLLs will have an import library generated (caused
when there are any exports), but because this DLL is so simple, it does
not. This makes ninja think that the target is always dirty and so it
rebuilds it on every build. Fix this by telling ninja not to expect an
import library.

bf556829d9 win: support x64 reading x86 (wow64)
Removes the bitness-specific targets in favour of pulling binaries from
the other build directory. This is to avoid the added complexity of
duplicating all the targets for the x86 in x64 build.

Overall, mostly templatizing more functions to support the
wow64-flavoured structures. The only additional functionality required
is reading the x86 TEB that's chained from the x64 TEB when running
as WOW64.

The crashing child test was switched to a manual CreateProcess because
it needs to launch a binary other than itself.

6978bf7646 win: Crash handler server
This replaces the registration server, and adds dispatch to a delegate
on crash requests.

(As you are already aware) we went around in circles on trying to come
up with a slightly-too-fancy threading design. All of them seemed to
have problems when it comes to out of order events, and orderly
shutdown, so I've gone back to something not-too-fancy.

Two named pipe instances (that clients connect to) are created. These
are used only for registration (which should take <1ms), so 2 should be
sufficient to avoid any waits. When a client registers, we duplicate
an event to it, which is used to signal when it wants a dump taken.

The server registers threadpool waits on that event, and also on the
process handle (which will be signalled when the client process exits).
These requests (in particular the taking of the dump) are serviced
on the threadpool, which avoids us needing to manage those threads,
but still allows parallelism in taking dumps. On process termination,
we use an IO Completion Port to post a message back to the main thread
to request cleanup. This complexity is necessary so that we can
unregister the threadpool waits without being on the threadpool, which
we need to do synchronously so that we can be sure that no further
callbacks will execute (and expect to have the client data around
still).

In a followup, I will readd support for DumpWithoutCrashing -- I don't
think it will be too difficult now that we have an orderly way to
clean up client records in the server.

6083a2706d Recognize crashreporter_annotations_t version 5 found on OS X 10.11.
The system’s crashreporter_annotations_t structure was always present
as version 4 since Mac OS X 10.7. In OS X 10.11, it is now present as
version 5. It has also grown from 56 to 64 bytes per otool examination
of CoreFoundation’s __DATA,__crash_info section. The extra 8 bytes are
presumed to be a new field at the end of the structure, although this
is not confirmed.

The existing MachOImageAnnotationsReader.CrashAbort test only validated
that the “message” field in crashreporter_annotations_t was recovered
correctly, but
MachOImageAnnotationsReader::ReadCrashReporterClientAnnotations() also
recovers the “message2” field. A new test,
MachOImageAnnotationsReader.CrashModuleInitialization, is added to
ensure that the “messgae2” field can be recovered properly.

This change will resolve warnings such as:
[pid:tid:yyyymmdd,hhmmss.uuuuuu:WARNING
mach_o_image_annotations_reader.cc:82] unexpected crash info version 5
in
/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation

5e8e72f91c Don’t use DYLD_INSERT_LIBRARIES with a system executable.
OS X 10.11 introduces System Integrity Protection. One facet of that
forbids code injection into system executables. A Crashpad test checks
that information can be recovered from dyld in early-launch crashes by
requesting dyld load a nonexistent library with DYLD_INSERT_LIBRARIES.
The executable was meaningless but a system-provided executable,
/usr/bin/true, was used for convenience.

This test hung on OS X 10.11 because DYLD_INSERT_LIBRARIES was ignored
for the system executable, and no crash occurred. The test waited for a
crash that would never come.

A custom no-op executable, crashpad_snapshot_test_no_op, is provided as
an executable that does work with DYLD_INSERT_LIBRARIES.

69d135acda win: make CrashpadInfo retrievable
The main goal was to get the beginnings of module iteration and retrieval
of CrashpadInfo in snapshot. The main change for that is to move
crashpad_info_client_options[_test] down out of mac/.

This also requires adding some of the supporting code of snapshot in
ProcessReaderWin, ProcessSnapshotWin, and ModuleSnapshotWin. These are
partially copied from Mac or stubbed out with lots of TODO annotations.
This is a bit unfortunate, but seemed like the most productive way to
make progress incrementally. That is, it's mostly placeholder at the
moment, but hopefully has the right shape for things to come.

809ea8158d test: Move util/test to its own top-level directory, test.
After 9e79ea1da719, it no longer makes sense for crashpad_util_test_lib
to “hide” in util/util_test.gyp. All of util/test is moved to its own
top-level directory, test, which all other test code is allowed to
depend on. test, too, is allowed to depend on all other non-test code.

In a future change, when crashpad_util_test_lib gains a dependency on
crashpad_client, it won’t look so weird for something in util (even
though it’s in util/test) to depend on something in client, because the
thing that needs to depend on client will live in test, not util.

9e79ea1da7 Split *_test.gyp from *.gyp.
In a future change, crashpad_util_test_lib will gain a dependency on
crashpad_client. This would violate GYP’s prohibition on circular
dependencies between .gyp files, although there would be no circular
relationship between the targets themselves. To overcome this problem,
all test-related targets are moved into their own first-class .gyp
files.
