* fix pointer style to match the style guideMike Frysinger2020-07-151-2/+2
| | | | | | | | | | We do this in a lot of places, but we're inconsistent. Normalize the code to the Google C++ style guide.

* Delete deprecated SetFirstChanceExceptionHandler functionAndreas Haas2019-02-191-5/+0
| | | | | | | | | | | | | | | This CL removes the code I marked as deprecated in https://crrev.com/c/1411776. I could not delete the code in that CL before I removed all uses in Chrome in https://crrev.com/c/1411643. The tracking bug contains more information.

* Introduce SetFirstChanceHandler with more strict signatureAndreas Haas2019-01-151-2/+6
| | | | | | | | | | | | | | | | | | | Eventually, I want to remove the current version of SetFirstChanceHandler. That is why I changed the name of the current callback type to FirstChanceHandlerDeprecated. I also made sure that it is not possible to have two different FirstChanceHandlers set at the same time. This is the first of a set of CLs to clean up the API between Chrome, BreakPad, and V8. See more information in the tracking bug.

* Add first chance exception handler APIEric Holk2017-06-191-0/+4
| | | | | | | | | | | | | | This change adds the option for Breakpad hosts to register a callback that gets the first chance to handle an exception. The handler will return true if it handled the exception and false otherwise. The primary use case is V8's trap-based bounds checking support for WebAssembly.

| | | | | | | | | | | | | This bug manifests itself on Android x64 (in ExceptionHandlerTest::ExternalDumper), but is possible on any platform. The compiler is unaware of the code which runs in the signal handler which reads this variable.

* Properly redeliver (or don't) signals to the previous handlers.mark@chromium.org2012-09-041-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* Improve Android supportdigit@chromium.org2012-08-211-3/+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
