281be63d00 Standardize on static constexpr for arrays when possible
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.

bc7c6e235d mac: Prevent the same report from being uploaded multiple times
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.

Test: crashpad_client_test CrashReportDatabaseTest.*

afc177ee21 Pull metrics instrumentation out to central file
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.

Also rolls mini_chromium DEPS to include:
99213eb Mark histogram arguments as unused to avoid warnings

553a643475 crashpad_database_util: Don’t create a database unless explicitly asked
I’ve accidentally created Crashpad databases when running
crashpad_database_util by mistyping the argument to --database. Typical
users of crashpad_database_util probably don’t want the database to be
created.

This adds a new --create option to crashpad_database_util that is
required to get it to create a database. If not present, a database will
not be created if it does not already exist.

6bf80c3e48 Add MinidumpCrashpadInfo::report_id.
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.

7d5e17cd2e CrashReportDatabase::Initialize(): use the database path.
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.

79177046d3 Mac 10.6 SDK compatibility.
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().

0849154aed win: Implementation of CrashReportDatabase for Windows
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.

5d0050dee7 Add CrashReportDatabase::ErrorWritingCrashReport().
A crash handler needs a way to clean up after itself it it calls
CrashReportDatabase::PrepareCrashReport() to begin writing a new crash
report, but then encounters an error that renders the crash report
unusable. The new ErrorWritingCrashReport() method allows it to
communicate to the database that a previously-prepared crash report
should be removed without ever being promoted to a completed report
pending upload.
