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.
This updates mini_chromium to 8a2363f486e3a0dc562a68884832d06d28d38dcc,
which removes base/basictypes.h.
e128dcf10122 Remove base/move.h; use std::move() instead of Pass()
8a2363f486e3 Move basictypes.h to macros.h

This more-natural spelling doesn’t require Crashpad developers to have
to remember anything special when writing code in Crashpad. It’s easier
to grep for and it’s easier to remove the “compat” part when pre-C++11
libraries are no longer relevant.

FILE_TYPE_CHAR handles can't be inherited via
PROC_THREAD_ATTRIBUTE_HANDLE_LIST, or CreateProcess() fails with
GetLastError() == 1450 on Windows 7.
I confirmed that an fprintf(stderr, ...) in HandlerMain() does make it
to the console when running tests even after this.

This consolidates all of the twisted casts and comments that discuss how
HANDLEs are really only 32 bits wide even in 64-bit processes on 64-bit
operating systems into a single location.

Allowing the client to create its own pipe name string caused a race
between client and server. Instead, in this mode, the server now creates
the pipe name along with a pipe, and returns it to its client via a
--handshake-handle. This guarantees that by the time the client gets the
pipe name, the server has already created it.
Ephemeral mode is now implied by --handshake-handle. The --persistent
option is gone. --persistent mode is enabled when using --pipe-name.

By invoking crashpad_handler with --mach-service instead of
--handshake-fd, the handler will run as a well-behaved launchd job. The
launchd job may be as a launch agent or launch daemon, or be submitted
to launchd by on_demand_service_tool.

For multiprocess architectures, this method allows the pipe used for
registration to be obtained from CrashpadHandler, even when
CrashpadHandler chooses its own name. This may happen if the handler is
not running on a well-known pipe name but was instead started by
CrashpadHandler::StartHandler(). If Chrome uses this interface, for
example, the browser process will need to call
CrashpadClient::GetHandlerIPCPipe() and pass the pipe name to its child
processes.

Previously, crashpad_handler made its own receive right, and transferred
a corresponding send right to its client. There are two advantages to
making the receive right in the client:
- It is possible to monitor the receive right for a port-destroyed
notificaiton in the client, allowing the handler to be restarted if
it dies.
- For the future run-from-launchd mode (bug crashpad:25), the handler
will obtain its receive right from the bootstrap server instead of
making its own. Having the handler get its receive right from
different sources allows more code to be shared than if it were to
sometimes get a receive right and sometimes make a receive right and
transfer a send right.
This includes a restructuring in crashpad_client_mac.cc that will make
it easier to give it an option to restart crashpad_handler if it dies.
The handler starting logic should all behave the same as before.

The intended use is to flip the client-server relationship in
CrashpadClient so that the initial client (parent process) furnishes the
handler process with a receive right. The parent can optionally receive
a port-destroyed notification allowing it to restart the handler if it
exits prematurely.

Fixes two incorrect usages of ssize_t/off_t being implicitly converted
to bool. As such, I think it's worth the cost of the additional !! on
BOOL returning Win32 functions.

In https://codereview.chromium.org/1411523006, the Mach port scopers are
becoming better ScopedGenerics and are losing the type conversion
operators in the process. This is needed to adapt to that change. get()
is ugly, but being explicit about conversion isn’t a bad thing, and
these scopers will gain functionality such as Pass() as part of the
switch.
As a bonus, some would-be uses of get() to check for valid port rights
are becoming a more descriptive is_valid().

I thought I had confirmed that this still allocated and ignored the flag
on older OSs, but I must have not had the PLOG active yet? I'm not sure
what I did. (I might try to blame VMware as it has an annoying habit of
caching old binaries when you use it's "Shared Folders" feature to point
at the dev machine's build dir.)
I confirmed that it does work on Win8 and Win10 but doesn't on Win XP
and Win 7.

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.

Previously, any attempt to create a new crash report database would
result in this message being logged:
[p:t:yyyymmdd,hhmmss.uuuuuu:ERROR file_io.cc:30] read: expected 40,
observed 0
This would be the first thing that a developer embedding Crashpad into
their application would see after getting everything right. It doesn’t
exactly seem like everything’s right with that being logged. It would
also be the first thing that a user would see on stderr or in logs upon
launching a Crashpad-enabled application, which also seems kind of
dodgy.
The crash report database settings creation logic is restructured to
avoid logging this error when definitely creating a new database, while
retaining all other error logging.

ExceptionPorts::GetExceptionPorts() returned a
std::vector<ExceptionPorts::ExceptionHandler>, which contained send
rights to Mach ports. The interface required callers to assume ownership
of each send right contained within the vector. This was cumbersome and
error-prone, and despite the care taken in Crashpad, port right leaks
did occur:
- SimulateCrash() didn’t make any attempt to release these resources at
all.
- Neither did crashpad_util_test ExceptionPorts.HostExceptionPorts,
which also reused a vector.
This replaces the vector with the interface-compatible (as far as
necessary) ExceptionPorts::ExceptionHandlerVector, which deallocates
collected port rights on destruction or clear().

If the task’s exception handler for EXC_CRASH, EXC_RESOURCE, and
EXC_GUARD exceptions cannot be set, clear the handler instead.
Nothing considered this function’s return value, and the only viable
fallback action on failure would have been to do what the function now
does, so its return type is changed to void.

Chrome’s relauncher process needs a way to sever ties with the
crashpad_handler instance running from the disk image in order to cause
that instance to exit so that the disk image may be unmounted. This new
function is otherwise not thought to be interesting, and its use is not
recommended.
This comes with a small refactoring to create a
SystemCrashReporterHandler() function, and a fix for a minor port leak
in CrashReportExceptionHandler::CatchMachException().

Windows requires the connection to the handler to do anything, so it
can't really be implemented or tested without CrashpadClient and the
