* There is no need to use the main queue just for perform selector.George Kola2017-02-131-34/+31
| | | | | | | | | | | | | | | | | | | | | | | | | We were using the main queue to queue up a perform selector and then the code [self sendStoredCrashReports] was immediately doing a dispatch_async. This unnecessary thread switching is not needed. We simplify the above logic and use dispatch_after to queue the block on the internal queue after a delay Note that main queue is typically more loaded and it is better for non-UI code to not use the main queue. This may also help improve crash log upload. This change also switches from @synchronized to dispatch_once as that is faster Reference: http://googlemac.blogspot.com/2006/10/synchronized-swimming.html BUG= Change-Id: I81035149cbbf13a3058ca3a11e6efd23980f19ad Reviewed-on: https://chromium-review.googlesource.com/441364 Reviewed-by: Joshua Peraza <jperaza@chromium.org>

* Add API to skip dump if crashing thread doesn't reference a given moduleTobias Sargeant2017-01-1810-62/+149
| | | | | | | | | | | | | | | | | | | | | | | | This CL makes it possible to skip a dump if the crashing thread doesn't have any pointers to a given module. The concrete use case is WebView where we would like to skip generating microdump output when webview is unreferenced by the stack and thus cannot be responsible for the crash in a way that would be debuggable. The range of interesting addresses is chosen by examining the process mappings to find the one that contains a pointer that is known to be in the right shared object (i.e. an appropriately chosen function pointer) passed from the client. If the extracted stack does not contain a pointer in this range, then we do not generate a microdump. If the stack extraction fails, we still generate a microdump (without a stack).

* Added classes to support reading unloaded module lists in minidumps.Joshua Peraza2016-12-166-1/+685
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The implementations of Module/UnloadedModule and ModuleList/UnloadedModuleList are very similar. They have been made separate classes because they operate on different structs, complicating factoring code into a base class and have sufficiently different implementation that templates would not be suitable. When unloaded modules have partially overlapping ranges, the module shrink down feature is used to move the start of the higher range to the end of the lower range. If two unloaded modules overlap identically, the second module will not be added to the range map and the failure ignored. Places where MinidumpUnloadedModule differs from MinidumpModule: code_identifier: the android/linux case is deleted since cv_records never exist. debug_file/debug_identifier/version: always return empty strings. Read: an expected size is provided as opposed to MD_MODULE_SIZE. A seek is used if there are extra, unused bytes. Places where MinidumpUnloadedModuleList differs from MinidumpModuleList: Read: entry and header size is provided in the header in addition to count. This changes the checks and handling of padding. Failures from StoreRange are ignored. GetMainModule: always returns NULL.

* Also treat DBG_PRINTEXCEPTION* as debug exceptionsTim Angus2016-10-181-1/+3
| | | | | | | | | | | | | Windows 10 now raises an exception when OutputDebugString* are called: (https://ntquery.wordpress.com/2015/09/07/windows-10-new-anti-debug-outputdebugstringw/) This change ignores these exception types such that they're not falsely identified as a crash.

* Provide initial EBX value to FPO frame data evaluatorScott Graham2016-10-142-6/+153
| | | | | | | | | | | | | EBX is sometimes used in "WIN FRAME 4" programs. Not providing the initial value was causing the evaluation in some frames of ntdll, resulting in a fallback to scanning and a failed stack walk.

* Don't call _exit() on iOS.Justin Cohen2016-10-131-0/+5
| | | | | | | | | | | | | Calling _exit() is something iOS inherited from Mac OS X Breakpad, and isn't necessary on iOS. This is necessary because recently iOS has started re-launching the application if breakpad catches a startup crash and calls exit during startup.

* Initial support for dumping DWARF corresponding to Swift codeMark Mentovai2016-09-236-33/+130
| | | | | | | | | | | | | | | | | | | | | | | | | | | The DWARF data for Swift code has a top-level DW_TAG_module DIE as the child of the DW_TAG_compile_unit DIE and the parent of the DW_TAG_subprogram DIEs that dump_syms uses to locate functions. dump_syms needs to process DW_TAG_module DIEs as introducing nested scopes to make it work with Swift. This also reworks demangling to be language-specific, so that the C++ demangler isn't invoked when processing Swift code. The DWARF data for Swift code presents its mangled names in the same form as used for C++ (DW_AT_MIPS_linkage_name or DW_AT_linkage_name) but the mangling is Swift-specific (beginning with _T instead of _Z). There is no programmatic interface to a Swift name demangler as an analogue to C++'s __cxa_demangle(), so mangled Swift names are exposed as-is. Xcode's "xcrun swift-demangle" can be used to post-process these mangled Swift names on macOS. Support for mangled names presented in a DW_AT_linkage_name attribute, as used by DWARF 4, is added. This supersedes the earlier use of DW_AT_MIPS_linkage_name. BUG=google-breakpad:702,google-breakpad:715 R=ted.mielczarek@gmail.com Review URL: https://codereview.chromium.org/2147523005 .
* generate a repo manifest from the DEPS fileMike Frysinger2016-09-211-0/+167
| | | | | | | | | | This allows people to use repo to manage the checkout instead of gclient. This helps when you're used to the standard repo+gerrit workflow that the Android & Chromium OS projects use.
