* 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.

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).
