This uses “static” at function scope to avoid making local copies, even
in cases where the compiler can’t see that the local copy is
unnecessary. “constexpr” adds additional safety in that it prevents
global state from being initialized from any runtime dependencies, which
would be undesirable.
At namespace scope, “constexpr” is also used where appropriate.
For the most part, this was a mechanical transformation for things
matching '(^| )const [^=]*\['.
Similar transformations could be applied to non-arrays in some cases,
but there’s limited practical impact in most non-array cases relative to
arrays, there are far more use sites, and much more manual intervention
would be required.

With multiple crashpad_handlers running out of the same database, it was
possible for more than one to attempt to upload the same report. Nothing
ensured that the reports remained pending between the calls to
CrashReportDatabaseMac::GetPendingReports() and
CrashReportDatabaseMac::GetReportForUploading().
The Windows equivalent did not share this bug, but it would return
kBusyError. kReportNotFound is a better code.

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.

Solves two problems with having the macros inline:
1. Deduplicates some of the logic (in this case, the name of the
histogram, and whether it should be divided by 1024);
2. More useful check for compilation. As the macros are no-ops in
Crashpad, it was easy to use the wrong name for a variable in the
arguments to the macros (see .mm!)
This way, we have some better chance of at least having code that
compiles when built in Chromium if all the arguments are passed to
Metrics::Something() in a standalone build.

This was done in Chromium’s local copy of Crashpad in 562827afb599. This
change is similar to that one, except more care was taken to avoid
including headers from a .cc or _test.cc when already included by the
associated .h. Rather than using <stddef.h> for size_t, Crashpad has
always used <sys/types.h>, so that’s used here as well.

The new call is also used in
CrashReportDatabaseWin::PrepareNewCrashReport(). Previously, that method
used the UUID::InitializeFromBytes() constructor. That actually caused
various fields of the UUID to be byte-swapped so that the ::UUID and
crashpad::UUID would be different UUIDs. Although a UUID is mostly
random, the version field in data_3 is used as a namespace and should be
4 for random UUIDs, and this was not the case under swapping.

Now that Chrome’s about:crashes displays the crash report UUID, I wanted
to add it to the minidump. In the future, we may be able to index these
on the server. This will also help identify dumps that correspond to the
same event once we’re equipped to convert between different formats.
Ideally, this new field is populated with the same UUID used locally in
the crash report database. To make this work,
CrashReportDatabase::NewReport must carry the UUID. This was actually
part of CrashReportDatabaseWin’s private extension to NewReport, so that
extension subclass can now be cleaned up.

Rather than accepting the path to the database’s parent directory, this
now accepts the path to the database itself. Using the parent directory
proved cumbersome in practice. When testing crashpad_handler with a
variety of databases, it is useful to be able to specify
--database=/tmp/crashpad_database, --database=/tmp/crashpad_database_2,
etc. The old interface required that these directories be created as a
separate step, and would put the actual database at
/tmp/crashpad_database/Crashpad. This was contrary to the operation of
most tools and interfaces, which would only require that /tmp exist and
would put the database at /tmp/crashpad_database.

A couple of the problems related to not having a C++11 library:
- You can’t put const elements into a std::vector<>, so
CrashReportDatabase::GetPendingReports() and
CrashReportDatabase::GetCompletedReports() need to change. There was
no data-safety benefit to const elements.
- std::string::pop_back() does not exist, another mechanism must be
used to trim strings in BreakpadHTTPFormParametersFromMinidump().
One relates to a feature that does not exist in 10.6:
- The O_CLOEXEC flag to open() was introduced in 10.7. Although it
would be possible to use fcntl(..., F_SETFD, FD_CLOEXEC) on 10.6, the
O_CLOEXEC behavior is just removed from
CrashReportDatabaseMac::ObtainReportLock(), in line with other open()
calls in Crashpad.
And one was a real bug:
- #define __STDC_FORMAT_MACROS before #including <inttypes.h> to get
format macros like SCNx32, used in UUID::InitializeFromString().

As there are no extended file attributes available on all Windows file
systems (NTFS supports alternate data streams, but Chrome still supports
running on FAT), instead of using metadata attached to the file, metadata
is stored separately in a simple record-based file and keyed by UUID.
Initially, I attempted a metadata file beside each report, each locked
separately more closely mirroring the Mac implementation. But given the
expected number of of active reports (in the 10s to 100s range?) and the
size of the metadata for each, simply storing it all in one file is much
less complicated when considering error situations.
If the serialization/deserialization becomes a measurable problem, it
could be optimized at some complexity by reading/writing only as
necessary, or optimizing the storage.
