The 32-bit process_types definition of dyld_all_image_infos winds up
with four extra bytes of tail padding when built into a 64-bit
crashpad_handler compared to a 32-bit one, and compared to the
structure’s native size. This prevents a 64-bit crashpad_handler from
being able to create a module snapshot of a 32-bit process for
dyld_all_image_infos versions 14 (since 10.9) and 15 (since 10.12).
Work around this by placing a zero-length “end” marker and using
offsetof(dyld_all_image_infos, end) in preference to
sizeof(dyld_all_image_infos).

This installs signal handlers in the crashpad_handler process to log
these crashes via the Crashpad.HandlerCrash.ExceptionCode.Mac histogram.
This is roughly the same mechanism that’s used for Windows.
The signal handler tries fairly hard to avoid swallowing signals, so
that things appear to outside observers (including debuggers and crash
handlers) identically to how they would look if no signal handler was
present.
The signal handler uses a different mapping schema than the existing
Crashpad.ExceptionCode.Mac histogram for reasons explained in code
comments. Because the mappings should not overlap, the new values may be
added to the existing CrashpadMacExceptionCodes enum.

Since it’s possible to receive an EXC_CRASH for any signal that
generates a core by default even if the signal did not originate from a
Mach exception, update the tests to ensure that all such signals can be
unwrapped from an exception properly. This happens when a signal such as
SIGSEGV is sent with kill(), for example.

Previously, only the top-level exception code was reported via the
Crashpad.ExceptionCode.Mac histogram. Making this histogram work
(https://crbug.com/678720) has revealed that Chrome is triggering
EXC_RESOURCE exceptions at a rate in excess of 4x that of ordinary
crashes. These exceptions were not previously visible because they are
not uploaded unless the system treats them as fatal, which it does not
normally do absent an explicit request.
In order to learn more about the problem, this change augments the data
reported via the Crashpad.ExceptionCode.Mac histogram to report (at
least) second-level exception data. This means that we will no longer
see just EXC_RESOURCE, but potentially more useful information such as
EXC_RESOURCE / RESOURCE_TYPE_IO / FLAVOR_IO_PHYSICAL_WRITES. This also
applies to other exception types, so that the majority of crashes
currently falling into the EXC_CRASH bucket will now have additional
information decoded and will be reported as, for example, EXC_BAD_ACCESS
/ KERN_INVALID_ADDRESS, EXC_BAD_INSTRUCTION / EXC_I386_INVOP, and
EXC_CRASH / SIGABRT.
Because the old mechanism was only live (in an “it works” sense) for
several days, and the new mechanism does not overlap with histogram
values used by the old one, there’s no need to invent a new histogram
name.

ConvertStringSecurityDescriptorToSecurityDescriptor() is used when
creating the initial connection pipe. Because this is done from inside
DllMain(), we cannot use advapi32 (where this function is). Instead,
save the binary representation of the self-relative SECURITY_DESCRIPTOR.
It is conceivable that this could change, but unlikely as this is the
same blob that would be stored on a file in NTFS.
Another potential approach would be to not make the pipe available to
all integrity levels here, and instead modify the Chromium sandbox code
to allow a specific pipe name prefix that would have to correspond with
the pipe name that Crashpad creates.
Similarly, UuidCreate() (used when initializing the database) is in a

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,

Most of the world, including the Chromium universe, seems to be
standardizing on Markdown for documentation. Markdown provides the
benefit of automatic rendering on Gitiles (Gerrit), and on GitHub
mirrors as well. Crashpad should fit in with its surroundings.
There are two quirks that I was unable to resolve.
- Markdown does not allow **emphasis** within a ```code fence```
region. In blocks showing interactive examples, the AsciiDoc
documentation used this to highlight what the user was expected to
type.
- Markdown does not have a “definition list” (<dl>). This would have
been nice in man pages for the Options and Exit Status sections.
In its place, I used unnumbered lists. This is a little ugly, but
it’s not the end of the world.
The new Markdown-formatted documentation is largely identical to the
AsciiDoc that it replaces. Minor editorial revisions were made.
References to Mac OS X now mention macOS, and tool man pages describing
tools that that access task ports now mention System Integrity
Protection (SIP).
The AppEngine-based https://crashpad.chromium.org/ app in doc/appengine
is still necessary to serve Doxygen-generated documentation. This app is
updated to redirect existing generated-HTML URLs to Gitiles’ automatic
Markdown rendering.
Scripts in doc/support are updated to adapt to this change. All AsciiDoc
support files in doc/support have been removed.

The Windows 10 loader starts a few extra threads before main(). In a few
of the test cases, the tests were relying on thread ordering (generally,
the test thread being at index #1). Instead, use other signals to find
the correct thread to verify.

crashpad_snapshot_test MachOImageAnnotationsReader.CrashDyld was failing
on 10.12.1. In 10.12, dyld’s intentional crashes come through
abort_with_payload(). In 10.12.1, it appears that the task port sent
along with abort_with_payload() crashes is now a corpse port, which has
a different port name than the task port that it originated from.

This defines the global (per-module) CrashpadInfo structure properly on
Linux/Android, located via the “crashpad_info” section name.
Per the ELF specification, section names with a leading dot are reserved
for the system. Reading that, I realized that the same is true of Mach-O
sections with leading underscores, so this renames the section as used
on Mach-O from __DATA,__crashpad_info to __DATA,crashpad_info.
This change is sufficient to successfully build crashpad_client as a
static library on Linux/Android, but the library is incomplete. There’s
no platform-specific database implementation, no CaptureContext() or
CRASHPAD_SIMULATE_CRASH() implementation, and most notably, no
CrashpadClient implementation.
