* 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.

* Fix the tools and processor build for Androiddigit@chromium.org2012-08-211-2/+2
| | | | | | | | | | | | | | | | | | This small patch allows the build of the tools and processor when targetting Android with the Automake/Autconf build. Not that these necessarily work correctly at the moment, but there is no need for --disable-tools --disable-processor now when using --host=arm-linux-androideabi or --host=i686-linux-android. + Modify android/run-checks.sh to build all binaries with the Automake build. + Tiny fix for --abi=x86 in android/run-checks.sh Review URL: https://breakpad.appspot.com/438002 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@1018 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Improve Android supportdigit@chromium.org2012-08-217-245/+1
| | | | | | | | | | | | | | | | | | This patch remove many Android-specific #ifdefs from the Breakpad source code. This is achieved by providing "fixed-up" platform headers (e.g. <signal.h> or <sys/user,h>), in the new directory src/common/android/include/, which masks differences between the NDK and GLibc headers. The old "android_link.h" and "android_ucontext.h" are moved and renamed. This also requires putting this directory as the first include path during Android-hosted builds, hence the modification of Makefile.am and configure.ac Review URL: https://breakpad.appspot.com/434002 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@1017 4c0a9323-5329-0410-9bdc-e9ce6186880e
