* Detect corrupt symbol files during minidump processing. Recover from the ↵ivan.penkov@gmail.com2013-07-1124-200/+524
| | | | | | | | | | | | | | | | | | | | | errors and use the good data if possible. More specifically: - Detect corrupt symbols during minidump processing and provide the list of modules with corrupt symbols in the ProcessState. This will allow listing the corrupt symbol files in the final crash report. - Skip and recover from symbol data parse errors - don't give up until 100 parse errors are seen. - In order to recover from '\0' (null terminator) in the middle of a symbol file, a couple of methods have to be updated to require both buffer pointer and length. Previously they required only a buffer pointer (char *) and the size of the buffer was evaluated using strlen which is not reliable when the data is corrupt. Most of the changes are due to these signature updates. - Added and updated unittests. Also, updated minidump_stackwalk to show a WARNING for corrupt symbols. Output looks like this: ...

* This change is addressing a particularly nasty issue where the stackwalkerivan.penkov@gmail.com2013-06-273-12/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | doesn't see the correct thread stack memory. Instead, it loads garbage (from offset 0 of the minidump file - well that's not garbage, but it is not the stack memory region either) and attempts to walk it. A typical symptom of this issue is when you get a single stack frame after processing - the context frame - for which you don't need stack memory. This issue is caused by an invalid RVA in the memory descriptor stored inside the MINIDUMP_THREAD structure for the thread. Luckily, the invalid RVA is 0, and the start_of_memory_region appears to be correct, so this issue can be easily detected and the correct memory region can be loaded using an RVA specified in the MinidumpMemoryList. I couldn't find a reasonable description on MSDN regarding MINIDUMP_MEMORY_DESCRIPTOR.MINIDUMP_LOCATION_DESCRIPTOR having RVA of 0 except maybe for full dumps where the 64-bit version of the structure (MINIDUMP_MEMORY_DESCRIPTOR64) is used and it has no RVA at all. It has a 64-bit DataSize which if interpreted as the 32-bit structure will very likely result in 0 for the RVA: http://msdn.microsoft.com/en-us/library/windows/desktop/ms680384(v=vs.85).aspx Anyways, the dump that I looked at was not a full dump so 0 for RVA is a bit puzzling (at least easily detectable): ...

* More robust stack walks when the IP address in the context frame is invalid ↵ivan.penkov@gmail.com2013-06-264-103/+341
| | | | | | | | | | | | | (or not in a known module). This is achieved by: 1. Extending the span of the scan for return address in the conext frame. Initially, I wanted to extend the span of the scan for all frames but then I noticed that there is code for ARM already that is extending the search only for the context frame. This kind of makes sense so I decided to reuse the same idea everywhere. 2. Attempting to restore the EBP chain after a successful scan for return address so that the stackwalker can switch back to FRAME_TRUST_CFI for the rest of the frames when possible. I also fixed the lint errors in the files touched.

* Improve ARM CPU info reporting.digit@chromium.org2013-04-242-0/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch improves several things for Linux/ARM: - Better detection of the number of CPUs on the target device. The content of /proc/cpuinfo only matches the number of "online" CPUs, which varies over time with recent Android devices. - Reconstruct the CPUID and ELF hwcaps values from /proc/cpuinfo, this is useful to better identify target devices in minidumps. - Make minidump_dump display the new information in useful ways. - Write a small helper class to parse /proc/cpuinfo and also use it for x86/64. - Write a small helper class to parse sysfds cpu lists. - Add a my_memchr() implementation. - Add unit tests. Tested on a Nexus S (1 CPU), Galaxy Nexus (2 CPUs) and a Nexus 4 (4 CPUs).

* Fix GetMainModule() to properly get first modulemkrebs@chromium.org2012-03-301-1/+1
| | | | | | | | | | | | | | | Change MinidumpModuleList::GetMainModule() to use GetModuleAtIndex() instead of GetModuleAtSequence() because the former gets the first module that was in the minidump file, while the latter actually gets the first module when sorted by address. While this is pretty much the same thing at the moment, I have another change in the works that can sometimes affect the module order in the file.
