2012-04-03Add missing log.o dependency to linux_client_unittest target.benchan@chromium.org
r945 introduced src/client/linux/log/log.c, which is used in exception_handler.cc, and thus should be added as a dependency in the linux_client_unittest target.

2012-01-19Implement core dump to minidump conversion.benchan@chromium.org
This patch is part of a bigger patch that helps merging the breakpad code with the modified version in Chromium OS. Specifically, this patch makes the following changes: 1. Turn the LinuxDumper class into a base class and move ptrace related code into a new derived class, LinuxPtraceDumper. 2. Add a LinuxCoreDumper class, which is derived from LinuxDumper, to extract information from a crashed process via a core dump file instead of ptrace. 3. Add a WriteMinidumpFromCore function to src/client/linux/minidump_writer/minidump_writer.h, which uses LinuxCoreDumper to extract information from a core dump file. 4. Add a core2md utility, which simply wraps WriteMinidumpFromCore, for converting a core dump to a minidump. BUG=455 TEST=Tested the following: 1. Build on 32-bit and 64-bit Linux with gcc 4.4.3 and gcc 4.6. 2. Build on Mac OS X 10.6.8 with gcc 4.2 and clang 3.0 (with latest gmock). 3. All unit tests pass. 4.

This patch is part of a bigger patch that helps merging the breakpad code with the modified version in Chromium OS. Specifically, this patch makes the following changes: 1. Add an ElfCoreDump class for processing Linux core dump files, which will later be used to implement the core dump to minidump conversion. 2. Add a CrashGenerator class for generating a crash with a core dump file for testing the functionalities of ElfCoreDump. 3. Move some utility functions for reading/writing files to file_utils.h.

2011-12-21Replace MMappedRange with MinidumpMemoryRange.benchan@chromium.org
This patch is part of a bigger patch that helps merging the breakpad code with the modified version in Chromium OS. The MemoryRange class was added in r895 (http://breakpad.appspot.com/332001), which is largely based on MMappedRange but generalized to be used in other code. However, MemoryRange does not support minidump data structures. This patch adds a MinidumpMemoryRange class that extends MemoryRange to handle minidump data structures, which can then replace MMappedRange. As with MemoryRange, MinidumpMemoryRange is unit tested. BUG=455 TEST=Tested the following: 1. Build on 32-bit and 64-bit Linux with gcc 4.4.3 and gcc 4.6. 2. Build on Mac OS X 10.6.8 with gcc 4.2 and clang 3.0 (with latest gmock). 3.

2011-12-21Replace readlink calls with a safer version that guarantees NULL-termination.benchan@chromium.org
This patch is part of a bigger patch that helps merging the breakpad code with the modified version in Chromium OS. Specifically, this patch makes the following changes: 1. Add a SafeReadLink function that wraps sys_readlink() to resolve a symbolic link but guarantees the result is NULL-terminated on success. 2. Refactor other source code to use SafeReadLink instead of readlink() or sys_readlink(). BUG=455 TEST=Tested the following: 1. Build on 32-bit and 64-bit Linux with gcc 4.4.3 and gcc 4.6. 2.

2010-03-16Breakpad processor: Support AMD64 stack unwinding driven by DWARF CFI.jimblandy
This adds support for 'STACK CFI' records (DWARF CFI) to the AMD64 stack walker. This is necessary for the stack trace to include any frames other than the youngest. Unit tests are included. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@554 4c0a9323-5329-0410-9bdc-e9ce6186880e
2010-03-16Breakpad: Support DWARF CFI-driven stack walking on ARM.jimblandy
This patch allows the Breakpad minidump processor to use data from STACK CFI records to generate stack traces for the ARM processor. In the symbol dumper, we need a table mapping DWARF CFI register numbers to their names: STACK CFI records refer to registers by name. In the processor, we expand StackwalkerARM::GetCallerFrame to see if there are STACK CFI records covering the callee, and then use those to recover the caller's register values. There's no good reason the ARM walker couldn't use the SimpleCFIWalker interface declared in cfi_frame_info.h. Unfortunately, that interface assumes that one can map register names to member pointers of the raw context type, while MDRawContextARM uses an array to hold the registers' values: C++ pointer-to-member types can't refer to elements of member arrays. So we have to write out SimpleCFIWalker::FindCallerRegisters in StackwalkerARM::GetCallerFrame. We define enum MDARMRegisterNumbers in minidump_cpu_arm.h, for convenience in referring to certain ARM registers with dedicated purposes, like the stack pointer and the PC. We define validity flags in StackFrameARM for all the registers, since CFI could theoretically recover any of them. In the same vein, we expand minidump_stackwalk.cc to print the values of all valid callee-saves registers in the context --- and use the proper names for special-purpose registers. We provide unit tests that give full code and branch coverage (with minor exceptions). We add a testing interface to StackwalkerARM that allows us to create context frames that lack some register values. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@553 4c0a9323-5329-0410-9bdc-e9ce6186880e
2010-03-16Breakpad: Add minidump processor support for DWARF Call Frame Information.jimblandy
Add a CFIFrameInfo class (named for symmetry with WindowsFrameInfo) to represent the set of STACK CFI rules in effect at a given instruction, and apply them to a set of register values. Provide a SimpleCFIWalker class template, to allow the essential CFI code to be shared amongst the different architectures. Teach BasicSourceLineResolver to partially parse 'STACK CFI' records, and produce the set of rules in effect at a given instruction on demand, by combining the initial rule set and the appropriate rule deltas in a CFIFrameInfo object. Adapt StackwalkerX86 and StackFrameX86 to retrieve, store, and apply CFI stack walking information. Add validity flags for all the general-purpose registers to StackFrameX86::ContextValidity. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@549 4c0a9323-5329-0410-9bdc-e9ce6186880e
