* Fix microdump_writer and add unittest.primiano@chromium.org2014-11-252-10/+150

* Introduce microdump writer class.primiano@chromium.org2014-10-287-21/+490
| | | | | | | | | | | | | | | | | | | Microdumps are a very lightweight variant of minidumps. They are meant to dump a minimal crash report on the system log (logcat on Android), containing only the state of the crashing thread. This is to deal with cases where the user has opted out from crash uploading but we still want to generate meaningful information on the device to pull a stacktrace for development purposes. Conversely to conventional stack traces (e.g. the one generated by Android's debuggerd or Chromium's base::stacktrace) microdumps do NOT require unwind tables to be present in the target binary. This allows to save precious binary size (~1.5 MB for Chrome on Arm, ~10 MB on arm64).

| | | | | | | | | | | | | | | | | | | | This change is a pure refactoring of the common bits of minidump_writer.cc that will be shared soon with the upcoming microdump_writer.cc. In particular, this CL is extracting the following classes: - ThreadInfo: handles the state of the threads in the crashing process. - RawContextCPU: typedef for arch-specific CPU context structure. - UContextReader: Fills out a dump RawContextCPU structure from the ucontext struct provided by the kernel (arch-dependent). - SeccompUnwinder: cleans out the stack frames of the Seccomp sandbox on the supported architectures. - MappingInfo: handles information about mappings BUG=chromium:410294 R=mmandlis@chromium.org Review URL: https://breakpad.appspot.com/4684002 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@1388 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Extend mapping merge to include reserved but unused mappings.rmcilroy@chromium.org2014-09-191-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When parsing /proc/pid/maps, current code merges adjacent entries that refer to the same library and where the start of the second is equal to the end of the first, for example: 40022000-40025000 r-xp 00000000 b3:11 827 /system/lib/liblog.so 40025000-40026000 r--p 00002000 b3:11 827 /system/lib/liblog.so 40026000-40027000 rw-p 00003000 b3:11 827 /system/lib/liblog.so When the system linker loads a library it first reserves all the address space required, from the smallest start to the largest end address, using an anonymous mapping, and then maps loaded segments inside that reservation. If the loaded segments do not fully occupy the reservation this leaves gaps, and these gaps prevent merges that should occur from occurring: 40417000-4044a000 r-xp 00000000 b3:11 820 /system/lib/libjpeg.so > 4044a000-4044b000 ---p 00000000 00:00 0 4044b000-4044c000 r--p 00033000 b3:11 820 /system/lib/libjpeg.so 4044c000-4044d000 rw-p 00034000 b3:11 820 /system/lib/libjpeg.so Where the segments that follow this gap do not contain executable code the failure to merge does not affect breakpad operation. However, where they do then the merge needs to occur. Packing relocations in a large library splits the executable segment into two, resulting in: 73b0c000-73b21000 r-xp 00000000 b3:19 786460 /data/.../libchrome.2160.0.so > 73b21000-73d12000 ---p 00000000 00:00 0 73d12000-75a90000 r-xp 00014000 b3:19 786460 /data/.../libchrome.2160.0.so 75a90000-75c0d000 rw-p 01d91000 b3:19 786460 /data/.../libchrome.2160.0.so Here the mapping at 73d12000-75a90000 must be merged into 73b0c000-73b21000 so that breakpad correctly calculates the base address for text. This change enables the full merge by also merging anonymous maps which result from unused reservation, identified as '---p' with offset 0, and which follow on from an executable mapping, into that executable mapping.

| | | | | | | | | | | | | | | | | | This CL adds three features that will allow the client to upload the report file. Three main modifications are made : - Allow upload url to have a file:// scheme, and write the HTTP request to file in that case - Split the request in two parts in case of a file:// scheme, the request time and the response time. A new API [handleNetworkResponse] is added. - Give the opportunity to the client to get the configuration NSDictionary to be able to recreate the breakpad context at response time.

| | | | | | | | | | | | | | | | | | | | | | APK file. This patch makes two changes to breakpad to enable crash reporting to work correctly when the library is inside another file (an archive): - Do not filter mappings which map an executable at a non-zero offset. - If such an executable is mapped look in the ELF information for the shared object name and use that name in the minidump. Note this change doesn't care about the archive format and isn't Android specific (though loading the shared library this way is currently only done on Android).

| | | | | | | | | | | | This CL adds breakpad_getcontext support for Arm64 to Android. The assembly is based on getcontext.S in glibc.

* First cut at adding arm64 Linux / Android support to Breakpad.rmcilroy@chromium.org2014-04-026-11/+68
| | | | | | | | | | | | | | This is an initial attempt to add Arm64 (aarch64) support to Breakpad for Linux / Android platforms. This CL adds the Arm64 data structures, but does not yet implement the Android getcontext support or CPUFillFromThreadInfo / CPUFillFromUContext.

* fix races in CrashGenerator::CreateChildCrashvapier@chromium.org2014-04-021-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current CreateChildCrash logic is racy when it comes to creating a crash dump for two reasons: The main thread that calls kill() on a different thread is guaranteed the signal will be *queued* when it returns, but not *delivered*. If the kernel doesn't automatically schedule the receiving thread, but instead lets the main thread run to the exit() call, then the signal never triggers a coredump and the whole process simply exits. The main thread is using kill() to try to deliver a signal to a specific thread, but that function is for sending signals to a process. That means the kernel is free to deliver the signal to any thread in the process and not just the one requested. This manifests itself as the pr_pid in the coredump not being the one expected. Instead, we must use tkill() with the tid (which we already took care of gathering) to deliver to a specific thread. These are a lot easier to see on a UMP system as contention is heavier.
