* increase exception handler stack size for dumping threadvapier@chromium.org2013-10-231-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When running unittests under ASAN, we see that these code paths can slightly smash the stack. Double it to avoid that.

* Improve ARM CPU info reporting.digit@chromium.org2013-04-246-126/+897
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Tested on a Nexus S (1 CPU), Galaxy Nexus (2 CPUs) and a Nexus 4 (4 CPUs).

* Fix three unit tests on recent ARM devices.digit@chromium.org2013-03-211-0/+24
| | | | | | | | | | | | Three unit tests were failing on recent ARM devices (e.g. Galaxy Nexus or Nexus 4), while ran properly on older ones (e.g. Nexus S). The main issue is that the instruction cache needs to be explicitely cleared on ARM after writing machine code bytes to a malloc()-ed page with PROT_EXEC.

* Add optional file size limit for minidumpsmkrebs@chromium.org2012-11-155-17/+266
| | | | | | | | | | | | | | | | | | | | | | 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.

* Make Linux signal handler more robust.digit@chromium.org2012-10-092-0/+60
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | - One of the unit test binaries refused to link due to missing linker flags. - The WriteDSODebug() function now works on Android, so do not special-case it anymore. - Ensure android/run-checks.sh will complain properly if the client unit test suite fails on Android. It used to consider that such failures were acceptable. Note that it still considers failures when running the tools and processor test suite on the device normal (fixing this is a lot harder, and these parts of Breakpad typically never run on a device, but on the host).

* Don't bail if a thread's stack pointer is invalidmkrebs@chromium.org2012-10-087-36/+137
| | | | | | | | | | | | | | Currently, if a thread's stack pointer is not within a valid memory page, the minidump writing will fail with an error. This change allows an invalid stack pointer by simply setting the memory size to zero in the minidump.

* Properly redeliver (or don't) signals to the previous handlers.mark@chromium.org2012-09-043-72/+304
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add custom getcontext() implementation for Android.digit@chromium.org2012-08-311-9/+3
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
