MINIDUMP_MISC_INFO_5 can carry information about extended XSTATE state
components and the process cookie value.
I made some informed guesses about the precise meanings of some of the
attributes of the XSTATE stuff.
I don’t know what “process cookie” refers to yet. My guess is that it’s
the stack canary value, or something similar. But since this isn’t an
informed guess, I haven’t written it into the documentation.
Crashpad does not yet use either of these features.

As I was finishing d98a4de718d9, it became evident that fsave
proliferation was becoming a problem. Especially considering tests,
there was much duplicated conversion code. This ties everything up
together in a central location.
test::BytesToHexString() is a new function to ease testing of byte
arrays like x87 registers, without having to loop over each byte.
Some static_asserts are added to verify that complex structures that
need to maintain interoperability don’t grow or shrink. This is used
to check the size of the fxsave and fsave structures, as well as the
MinidumpCPUContext* structures.

This adds zlib to Crashpad. By default in standalone Crashpad builds,
the system zlib will be used where available. A copy of Chromium’s zlib
(currently a slightly patched 1.2.11) is checked out via DEPS into
third_party for use on Windows, which does not have a system zlib.
zlib is used to produce gzip streams for HTTP upload request bodies sent
by crashpad_handler by default. The Content-Encoding: gzip header is set
for these compressed request bodies. Compression can be disabled for
upload to servers without corresponding decompression support by
starting crashpad_handler with the --no-upload-gzip option.
Most minidumps compress quite well with zlib. A size reduction of 90% is
not uncommon.

Chunked encoding doesn’t require the length of the request body to be
known in advance. In cases where this value isn’t independently known,
as is normal for Crashpad report uploads where the HTTP request body is
constructed on the fly, chunked encoding eliminates the need to prepare
the entire request body in memory before transmitting it. In these
cases, it’s much less wasteful.
When the length of the request body is known in advance, based on the
provision of a Content-Length header, chunked encoding is not used.
Even so, the request is sent in pieces rather than reading the entire
request into memory before sending anything.

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

being able to create a module snapshot of a 32-bit process for

Work around this by placing a zero-length “end” marker and using

This installs signal handlers in the crashpad_handler process to log

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

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

save the binary representation of the self-relative SECURITY_DESCRIPTOR.
It is conceivable that this could change, but unlikely as this is the

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

Clang extension.
http://clang.llvm.org/docs/LanguageExtensions.html#has-feature-and-has-extension
For GCC’s Address Sanitizer implementation, test the
__SANITIZE_ADDRESS__ macro that it provides as an alternative to
__has_feature(address_sanitizer).
Note that in Chrome builds, ADDRESS_SANITIZER is pushed in by the build
system. The definition of ADDRESS_SANITIZER provides another way for
that macro to be set. It’s supplementary, not exclusive.
