When GetProcessInformation() obtains SystemProcessInformation, it
resizes its buffer as directed by NtQuerySystemInformation(). Nothing of
value resides in the old buffer if a resize is attempted, so it can be
freed before attempting to allocate a resized one.
This may help crashes like go/crash/f385e94c80000000, which experience
out-of-memory while attempting to allocate a resized buffer. It also may
not help, because the required buffer size may just be too large to fit
in memory. See https://crashpad.chromium.org/bug/143#c19.

gtest used to require (expected, actual) ordering for arguments to
EXPECT_EQ and ASSERT_EQ, and in failed test assertions would identify
each side as “expected” or “actual.” Tests in Crashpad adhered to this
traditional ordering. After a gtest change in February 2016, it is now
agnostic with respect to the order of these arguments.
This change mechanically updates all uses of these macros to (actual,
expected) by reversing them. This provides consistency with our use of
the logging CHECK_EQ and DCHECK_EQ macros, and makes for better
readability by ordinary native speakers. The rough (but working!)
conversion tool is
https://chromium-review.googlesource.com/c/466727/1/rewrite_expectassert_eq.py,
and “git cl format” cleaned up its output.
EXPECT_NE and ASSERT_NE never had a preferred ordering. gtest never made
a judgment that one side or the other needed to provide an “unexpected”
value. Consequently, some code used (unexpected, actual) while other
code used (actual, unexpected). For consistency with the new EXPECT_EQ
and ASSERT_EQ usage, as well as consistency with CHECK_NE and DCHECK_NE,
this change also updates these use sites to (actual, unexpected) where
one side can be called “unexpected” as, for example, std::string::npos
can be. Unfortunately, this portion was a manual conversion.

This supports the “double handler” or “double handler with low
probability” models from https://crashpad.chromium.org/bug/143.
For crashpad_handler to be become its own client, it needs access to its
own executable path to pass to CrashpadClient::StartHandler(). This was
formerly available in the test-only test::Paths::Executable(). Bring
that function’s implementation to the non-test Paths::Executable() in
util/misc, and rename test::Paths to test::TestPaths to avoid future
confusion.
test::TestPaths must still be used to access TestDataRoot(), which does
not make any sense to non-test code.
test::TestPaths::Executable() is retained for use by tests, which most
likely prefer the fatal semantics of that function. Paths::Executable()
is not fatal because for the purposes of implementing the double
handler, a failure to locate the executable path (which may happen on
some systems in deeply-nested directory hierarchies) shouldn’t cause the
initial crashpad_handler to abort, even if it does prevent a second
crashpad_handler from being started.

ReadFile() attempted to continue reading after a short read. In most
cases, this is fine. However, ReadFile() would keep trying to fill a
partially-filled buffer until experiencing a 0-length read(), signaling
end-of-file. For certain weird file descriptors like terminal input, EOF
is an ephemeral condition, and attempting to read beyond EOF doesn’t
actually return 0 (EOF) provided that they remain open, it will block
waiting for more input. Consequently, ReadFile() and anything based on
ReadFile() had an undocumented and quirky interface, which was that any
short read that it returned (not an underlying short read) actually
indicated EOF.
This facet of ReadFile() was unexpected, so it’s being removed. The new
behavior is that ReadFile() will return an underlying short read. The
behavior of FileReaderInterface::Read() is updated in accordance with
this change.
Upon experiencing a short read, the caller can determine the best
action. Most callers were already prepared for this behavior. Outside of
util/file, only crashpad_database_util properly implemented EOF
detection according to previous semantics, and adapting it to new
semantics is trivial.
Callers who require an exact-length read can use the new
ReadFileExactly(), or the newly renamed LoggingReadFileExactly() or
CheckedReadFileExactly(). These functions will retry following a short
read. The renamed functions were previously called LoggingReadFile() and
CheckedReadFile(), but those names implied that they were simply
wrapping ReadFile(), which is not the case. They wrapped ReadFile() and
further, insisted on a full read. Since ReadFile()’s semantics are now
changing but these functions’ are not, they’re now even more distinct
from ReadFile(), and must be renamed to avoid confusion.

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).

Not directly related, but still relevant to documentation,
doc/support/generate.sh is updated to remove temporary removals of

Adds a new client API which allows causing an exception in another
process. This is accomplished by injecting a thread that calls
RaiseException(). A special exception code is used that indicates to the
handler that the exception arguments contain a thread id and exception
code, which are in turn used to fabricate an exception record. This is
so that the API can allow the client to "blame" a particular thread in
the target process.
The target process must also be a registered Crashpad client, as the
normal exception mechanism is used to handle the exception.
The injection of a thread is used instead of DebugBreakProcess() which
does not cause the UnhandledExceptionFilter() to be executed.
NtCreateThreadEx() is used in lieu of CreateRemoteThread() as it allows
passing of a flag which avoids calling DllMain()s. This is necessary to
allow thread creation to succeed even when the target process is
deadlocked on the loader lock.

Patch from Bruce Dawson <brucedawson@chromium.org>.
The BaseName() was added because system DLLs were being reported by
GetFileVersionInfo()/VerQueryValue() as having major file versions of
6.2 instead of 10.0 on Windows 10 when accessed by full path, but not
by BaseName(). The PEImageReader gets the correct version from the
in-memory images, 10.0.
This trick didn't work on Windows XP, where two copies of comctl32.dll
were found loaded into the process, one with a major file version of
5.82 and the other with 6.0. Giving GetFileVersionInfo() the BaseName()
would result in it returning information from one of these, which would
cause the version to not match when the PEImageReader was looking at the
other.
All of these GetFileVersionInfo() quirks make me glad that we're not
using it anymore (outside of the test).
Because of the version numbers involved (NT 6.2 = Windows 8, where
GetVersion()/GetVersionEx() start behaving differently for
non-manifested applications) and the fact that GetFileVersionInfo()
and VerQueryValue() seem to report 10.0 even with full paths on Windows
10 in applications manifested to run on that OS, the BaseName() thing is
restricted to Windows 8 and higher.
