There are a bunch of tests that use invalid memory acesses (on purpose)
to trigger a crash so that we can detect things are dumped correctly.
When we run under ASAN, it catches those accesses and the breaks the
testing flow.
For now, use the existing ADDRESS_SANITIZER symbol to disable more tests.
Ideally we'd use a compile-time attribute to disable ASAN on a few funcs,
but that seems to be broken atm.

SIGABRT can be generated internally, usually by calling abort(),
or externally by another process. When the signal is generated
by the kernel, info->si_pid is 0 and the signal is treated in the
same way as an exception (SIGSEGV, etc.), but the assumption
that the exception happens again upon return from the handler
is wrong, so we must have a special case for this.

Apparently, as of the 10.8 SDK, Apple has quietly decided that the first
argument to NSLocalizedString is supposed to be usable as-is as a format
string, instead of simply being the key to obtain a usable format string.
The recent clang trunk enforces this, resulting in build breaks like
crash_report_sender.m:560:14: error: data argument not used by format string [-Werror,-Wformat-extra-args]

^
Breaking the result of NSLocalizedString into a temporary NSString* is enough
to suppress the warning.

This patch improves several things for Linux/ARM:
- Better detection of the number of CPUs on the target
device. The content of /proc/cpuinfo only matches the
number of "online" CPUs, which varies over time with
recent Android devices.
- Reconstruct the CPUID and ELF hwcaps values from
/proc/cpuinfo, this is useful to better identify
target devices in minidumps.
- Make minidump_dump display the new information
in useful ways.
- Write a small helper class to parse /proc/cpuinfo
and also use it for x86/64.
- Write a small helper class to parse sysfds cpu lists.
- Add a my_memchr() implementation.
- Add unit tests.

If the stack sizes for threads in the MinidumpSizeLimit test are too big,
then subtracting 64KB from the normal minidump file size is not enough to

When there are upwards of 200 threads in a crashing process, each having an
8KB stack, this can result in a huge, 1.8MB minidump file. So I added a
parameter that, if set, can compel the minidump writer to dump less stack.
More specifically, if the writer expects to go over the limit (due to the
number of threads), then it will dump less of a thread's stack after the
first 20 threads.
There are two ways to specify the limit, depending on how you write minidumps:
1) If you call WriteMinidump() directly, there's now a version of the
function that takes the minidump size limit as an argument.
2) If you use the ExceptionHandler class, the MinidumpDescriptor object you
pass to it now has a set_size_limit() method you would call before
passing it to the constructor.

Breakpad can be used on processes where a mistaken
library saves then restores one of our signal handlers
with 'signal' instead of 'sigaction'.
This loses the SA_SIGINFO flag associated with the
Breakpad handler, and in some cases (e.g. Android/ARM
kernels), the values of the 'info' and 'uc' parameters
that ExceptionHandler::SignalHandler() receives will
be completely bogus, leading to a crash when the function
is executed (and of course, no minidump generation).
To work-around this, have SignalHandler() check the state
of the flag. If it is incorrectly unset, re-register with
'sigaction' and the correct flag, then return. The signal
will be re-thrown, and this time the function will be
called with the correct values.

If none of the installed ExceptionHandlers handle a signal (their
FilterCallbacks or HandlerCallbacks all return false), then the signal
should be delivered to the signal handlers that were previously
installed.
This requires that old_handlers_ become a static vector so that we can
restore the handlers in the static HandleSignal.
Currently it is also restoring signals in ~ExceptionHandler (if there
are no others). This should not be required since our documentation
states that a process can only have one ExceptionHandler for which
install_handlers is true (and so we get the correct behavior if we
simply leave our handlers installed forever), but even the tests
themselves violate that.

This adds a minimalistic implementation of getcontext()
for Android/ARM and Android/x86. The provided code is
in assembly and only implements the bare minimum required
by Breakpad to get the current processor state.
Note that:
- The FPU state is not saved to the ucontext_t on ARM.
(that's actually the main difference with a normal
getcontext() implementation).
This is normal. On Linux/ARM, such state must be
obtained with PTRACE_GETVFPREGS instead. This will
be implemented in a future patch.
- On x86, only the 'regular' FPU state is saved, to
mimic the GLibc/i386 implementation. The state of
SSE/SSE2/etc registers is not part of the upstream
getcontext() implementation.

This patch is part of a bigger patch that helps merging the breakpad code
with the modified version in Chromium OS.
Specifically, this patch makes the following changes:
1. Turn the LinuxDumper class into a base class and move ptrace related
code into a new derived class, LinuxPtraceDumper.
2. Add a LinuxCoreDumper class, which is derived from LinuxDumper, to
extract information from a crashed process via a core dump file instead
of ptrace.
3. Add a WriteMinidumpFromCore function to
src/client/linux/minidump_writer/minidump_writer.h,
which uses LinuxCoreDumper to extract information from a core dump file.
4. Add a core2md utility, which simply wraps WriteMinidumpFromCore, for
converting a core dump to a minidump.
BUG=455
TEST=Tested the following:
1. Build on 32-bit and 64-bit Linux with gcc 4.4.3 and gcc 4.6.
2. Build on Mac OS X 10.6.8 with gcc 4.2 and clang 3.0 (with latest gmock).
3. All unit tests pass.
4. Run Chromium OS tests to test core2md.

This patch is part of a bigger patch that helps merging the breakpad code
with the modified version in Chromium OS.
Specifically, this patch makes the following changes:
1. Add two convenient methods, back() and empty(), to the wasteful_vector
class.
2. Refactor the LinuxDumper class such that it can later be splitted into
a base class and two derived classes, one uses the current ptrace
implementation and one uses a core file.
3. Refactor the MinidumpWriter class such that it can later use different
derived implementations of LinuxDumper.

Manufacturing an exception record improves the crash reporting, since then
the crashes get bucketed by the call stack leading to the dump, instead of
all falling into a misc bucket that nobody ever looks at.
Currently these are occuring through e.g. dumps from the base watchdog.

This patch is part of a bigger patch that helps merging the breakpad code
with the modified version in Chromium OS.
Specifically, this patch makes the following changes:
1. Add a SafeReadLink function that wraps sys_readlink() to resolve a
symbolic link but guarantees the result is NULL-terminated on success.
2. Refactor other source code to use SafeReadLink instead of readlink()
or sys_readlink().

To be noted:
1) All is done in process, as multi-process is not allowed on ios.
2) Dump are saved when a crash occures but are not automatically send to the
server.
3) Breakpad.h contains function to check if a dump must be uploaded, and to
upload a dump.
4) The code is copy pasting a log of Breakpad implementation for Mac OS. It
might be possible to do some refactoring.

<Breakpad/BreakpadDefines.h>.
During the build of Breakpad itself (especially in Chromium), there is no
Breakpad.framework/Headers in which to locate BreakpadDefines.h, so the
framework-style #include of <Breakpad/BreakpadDefines.h> is not able to find
anything to #include. Using the "BreakpadDefines.h" form should always locate
this file next to Breakpad.h whether it's in the framework or in the source
tree.
This fixes a Chromium build regression caused by Breakpad r856.

This will be needed for iOS implementation, where the Inspector won't be
used, but where a config file will still be needed, because the uploads
won't happen just after the crash, but on a next run.

Regression from Breakpad r842 (Chromium r103778) - browser crash reports were
uploaded, but renderer crash reports were not. Messages such as these may have
been logged:
com.apple.launchd.peruser.x[y] could not lookup DNS configuration info
service: (ipc/send) invalid destination port

When OnDemandServer establishes the bootstrap subset, it will now register the
parent bootstrap port in the subset namespace so that the Inspector can
recover this port and switch to it. The Sender, launched by the Inspector,
relies on the bootstrap port being set properly.

TEST=All test cases from Chromium r103778 (bug chromium:28547) plus:
about:crash should generate a crash report which should be uploaded,
provided that throttling is not in effect. Remove or edit
~/Library/Preferences/com.Breakpad.crash_report_sender.plist to defeat
throttling. Also verify that about:inducebrowsercrashforrealz works.

TEST=Handler should still crash catches, but inspector ports should no longer
show up in "launchctl bslist". They should show up under a subset port in
"launchctl bstree" instead. "launchctl bstree" must be invoked as root.

split up into multiple regions.
An older workaround relyied on known fixed stack locations and only filled in
the initial page of the stack if it was in a distinct region. The new approach
looks upwards for additional regions that appear to be part of the same stack.
With PIE on Lion, the stack no longer begins at a fixed address, so the older
workaround became ineffective.
BUG=247, chromium:94107
TEST=Stacks should run through to _main/start and then stop when examining
Chrome on Lion with PIE and "slid" stacks.

This libcrypto dependency sucks. Linking against OpenSSL is sort of broken in
certain Mac OS X SDKs. libcrypto was only being used to provide an MD5
implementation. Breakpad already has its own MD5 implementation, so just use
that instead.
To be perfectly honest, on modern systems, nothing should be making MD5
hashes of modules anyway, because everything has an embedded LC_UUID.
The project file changes just remove libcrypto and add md5.c as needed.
A bonus (and untested) fix for on_demand_symbol_supplier.mm is included to
account for changes in r794.

Fix an assertion where a zero-length buffer was being passed to
UntypedMDRVA::Copy(). This occurred when WriteFile() was given a file whose
size was a multiple of the temporary buffer size. In this issue's case, the

was 1016 bytes.

tgkill() is not necessarily possible, as a sandbox might block this call.
This changelist tries different approaches depending on whether we received
a synchronous or an asynchronous signal. This fixes unittest failures and
also runs correctly in sandbox'd environments.

Inspector::ReadMessages as was done before r627. The "hello" message contains
the parameter count and is referenced while the message reader loops through
parameter messages. Prior to r627, both messages were named |message|, which
was confusing, probably caused a compiler warning, and apparently provided the
motivation to share them. This caused the crash inspector to fail to properly
collect the parameters. The common failure mode (although others are possible)
was for the inspector to attempt tor read more parameter messages than were
available, resulting in an IPC timeout and inspector death. No crash report
would be written, and the application expecting its crash to be inspected
would time out waiting for a response from the inspector and then _exit. This
is effectively a failure to properly handle crashes.
The inner message is reintroduced, and named parameter_message for
disambiguation.
