This change was partially scripted and partially done manually with vim
regex + manually placing the deleted constructors.
The script change looked for destructors in the public: section of a
class, if that existed the deleted constructors would go before the
destructor.
For manual placement I looked for any constructor in the public: section
of the corresponding class. If there wasn't one, then it would ideally
have gone as the first entry except below enums, classes and typedefs.
This may not have been perfect, but is hopefully good enough. Fingers
crossed.
#include "base/macros.h" is removed from files that don't use
ignore_result, which is the only other thing defined in base/macros.h.

Self-monitoring revealed this CHECK was being hit in the wild:
base::debug::BreakDebugger() debugger_posix.cc:260
logging::LogMessage::~LogMessage() logging.cc:759
logging::MachLogMessage::~MachLogMessage() mach_logging.cc:45
crashpad::ExceptionHandlerServer::Run() exception_handler_server.cc:108
crashpad::HandlerMain() handler_main.cc:744
The MACH_CHECK() was:
108 MACH_CHECK(mr == MACH_MSG_SUCCESS, mr) << "MachMessageServer::Run";
Crash reports captured the full message, including the value of mr:
[0418/015158.777231:FATAL:exception_handler_server.cc(108)] Check failed: mr == MACH_MSG_SUCCESS. MachMessageServer::Run: (ipc/send) invalid destination port (0x10000003)
0x10000003 = MACH_SEND_INVALID_DEST.
This can happen when attempting to send a Mach message to a dead name.
Send (and send-once) rights become dead names when the corresponding
receive right dies. This would not normally happen for exception
requests originating in the kernel. It can happen for requests
originating from a user task: when the user task dies, the receive right
dies with it. All it takes to trigger this CHECK() in crashpad_handler
is for a Crashpad client to die (or be killed) while the handler is
processing a SimulateCrash() that the client originated.
Accept MACH_SEND_INVALID_DEST as a valid return value for
MachMessageServer::Run().
Note that MachMessageServer’s test coverage was already aware of this
behavior. MachMessageServer::Run()’s documentation is updated to reflect
it too.

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.

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.

MachMessageServer::Run()’s distinct |nonblocking| parameter is removed.
The information it formerly conveyed is now implied by the |timeout_ms|
parameter, which can accept two special values,
kMachMessageTimeoutNonblocking and kMachMessageTimeoutWaitIndefinitely.

Previously, MachMessageServer::Run() only provided two strategies for
dealing with large messages, indicated by mach_msg() returning
MACH_RCV_TOO_LARGE: the receive buffer could be reallocated and the
message received, or the entire function could return MACH_RCV_TOO_LARGE
to the caller. There are situations where an intermediate behavior might
be desirable. This intermediate behavior would allow the function to
continue waiting for another message without returning an error to the
caller or attempting to receive the large message. This is desirable
when dealing with fixed-sized messages and a receiver that might be sent
messages by unknown, possibly-malicious callers. This can happen when
the corresponding send right is published with the bootstrap server, for
example.
Existing users continue to request their existing behavior, typically
receiving an error when encountering a large message.
catch_exception_tool will use the new “ignore” behavior when running in
persistent mode.

There’s no reason that “in” or “request” messages should be non-const.
This makes them const, bridges the const gap left by the MIG-generated
“check” functions with wrappers, and uses non-const fields in
“out” messages instead of const fields in “in” messages for in-out
parameters.

This also adds a COMPILE_ASSERT to check that the

MachMessageServer is much like mach_msg_server() and
mach_msg_server_once(), but with a C++ interface and with a number of
deficiencies corrected.
