* Allow minidump_dump to print module lists that would normally be rejectedTed Mielczarek2018-03-121-0/+3
| | | | | | | | | | | | | | | | | for being too long. We've seen some minidumps that fail to process because they contain a ridiculous number of modules (usually due to something leaking shm mappings, it looks like). They're annoying to investigate because even minidump_dump fails to load and print the module list. This patch makes minidump_dump effectively remove the limit on the number of modules it will load, so inspecting the dump by hand is possible.

* Only restore the signal handler if sigaction has not changedLars Volker2018-01-092-0/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Restoring the signal handler in ExceptionHandler::SignalHandler() can lead to a race in scenarios where multiple threads crash within a short time. This can cause threads to alternately try to write a minidump without ever terminating the process. The first thread to write a minidump will reset the signal handler to the SIG_DFL using signal() in InstallDefaultHandler(). The next thread to execute SignalHandler() will detect this and will reset the signal handler to SignalHandler(). If the first thread takes too long to write its minidump (e.g. when there are many threads), the chances increase that the second thread will enter SignalHandler() before the first one leaves the critical section. After resetting the signal handler, the second thread will fail to write a minidump (since the file already exists) and will try to reset the signal handler to the default by calling RestoreHandlersLocked(). However, in the meantime the first thread will have entered SignalHandler() again and will overwrite it one more time. After that, no further attempts will be made to restore the default signal handler and both threads will continue to re-raise the signal and attempt to write minidump files. This change adds a check to make sure that cur_handler.sa_sigaction is still pointing to SignalHandler() before re-installing the handler. To test this we start a large number of sleeping threads and two threads that will crash simultaneously. Without the fix, this would reproducibly lead to a loop between the two crashing threads.

This means that this code is illegal: void func(bool b) { if(b) goto END; int value = 0; //error C2362 with /permissive- //... value used here END: return; } Adding an extra scope makes the code legal. This problem is only detected with /permissive- but now that compiling with this switch is practical we might as well stay /permissive- clean: https://blogs.msdn.microsoft.com/vcblog/2016/11/16/permissive-switch/ Note that compiling /permissive- clean only works with the 10.0.16299.0 SDK which currently has other issues...

| | | | | | | | | | This hides the need to provide mutable C strings, and unifies existing basename calls and variations in a single location.

* Move main executable handling out of procmaps parser loop.Peter Collingbourne2017-10-171-19/+21
| | | | | | | | | | | | | | | | | | | | | | | | If the mapping for the main executable needed to be merged (for example, if it was linked with lld and therefore contains an r mapping followed by an r/x mapping), we would never reach the code that makes it the first module. Handle that situation by moving that code into a separate loop. This fixes an issue where breakpad_unittests fails on Android devices when linked with lld. It appears that the glibc dynamic loader happens to always load executables (or at least the executables that we create) at a lower address than DSOs, so we never hit this bug on desktop Linux. Testing: "make check" with both gold and lld as linker. Also breakpad_unittests when patched into Chromium on Linux (lld) and Android (gold and lld).

* Rename src/common/memory.h to memory_allocator.h.Ted Mielczarek2017-10-1715-33/+35
| | | | | | | | | | | | memory.h shadows a system header which normally isn't a problem because of the include paths in Breakpad, but the Firefox build system winds up with src/common in the include path so we've had a workaround for this for years. Renaming the file lets us get rid of that workaround and shouldn't hurt anything.

* Add -s flag to microdump_stackwalk for dumping stack contents.Tobias Sargeant2017-10-176-30/+32
| | | | | | | | | | | | | | | Note that the current MicrodumpProcessor::Process implementation has a bug due to the fact that it creates a local Microdump instance, and then holds onto a pointer to the object returned by microdump.GetMemory() which is destroyed when microdump goes out of scope. This CL fixes the crash by making Microdump outlive MicrodumpProcessor, which is the same pattern that Minidump/MinidumpProcessor uses.
