* Use register %ebp (instead of %esp) when calculating the value ofivan.penkov@gmail.com2013-11-052-13/+245
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | .raSearchStart in the cases where there are alignment operators in the program string. If alignment operators are found in the program string, the current value of %ebp must be valid and it is the only reliable data point that can be used for getting to the previous frame. Previously, the .raSearchStart calculation was based on %esp and when %esp is aligned in the current frame (which is a lossy operation) the resulting .raSearchStart cannot was incorrect. There is code that is trying to work around this problem (scanning of up to 3 words for a return address) which is unreliable and it doesn't work in many cases (e.g. when the alignment is on a 64-byte boundary). This fix is already deployed in Google and it was measured to reduce the number of wrong stack traces (for Windows crashes) by 45%. No regressions have been found so far. Here is an example of an issue that was fixed by this change (where register %esp is aligned on the 64-byte boundary and the workarounds that we already had didn't work): https://code.google.com/p/chromium/issues/detail?id=311359 0:013> uf chrome_59630000!base::MessagePumpForIO::DoRunLoop 518 59685c39 55 push ebp 518 59685c3a 8bec mov ebp,esp 518 59685c3c 83e4c0 and esp,0FFFFFFC0h <== 64-byte boundary 518 59685c3f 83ec34 sub esp,34h 518 59685c42 53 push ebx 518 59685c43 56 push esi Program string contains 64-byte alignment: $T1 .raSearch = $T0 $T1 4 - 64 @ = $ebp $T1 4 - ^ = $eip $T1 ^ = $esp $T1 4 + = $20 $T0 56 - ^ = $23 $T0 60 - ^ = $24 $T0 64 - ^ = Review URL: https://breakpad.appspot.com/694002 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@1232 4c0a9323-5329-0410-9bdc-e9ce6186880e

* NSLocalizedString compatibility (10.8 SDK and clang trunk -Wformat-extra-args)mark@chromium.org2013-11-051-12/+12
| | | | | | | | | | | | | | | | | | | | | Apparently, as of the 10.8 SDK, Apple has quietly decided that the first argument to NSLocalizedString is supposed to be usable as-is as a format string, instead of simply being the key to obtain a usable format string. The recent clang trunk enforces this, resulting in build breaks like crash_report_sender.m:560:14: error: data argument not used by format string [-Werror,-Wformat-extra-args] displayName]; ^ Breaking the result of NSLocalizedString into a temporary NSString* is enough to suppress the warning.

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: ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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): ...

| | | | | | | | | | | | | (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.

| | | | | | | | | | | | proposal for the fix. There's a bug in the new allocator<T> implementation used by wasteful_vector. It inherits the base class' implementation of allocator and doesn't implement allocate() so it goes to the heap instead of the PageAllocator -- the very thing wasteful_vector was trying to avoid! As a side effect it was also leaking heap memory.
