* Implement core dump to minidump conversion.benchan@chromium.org2012-01-193-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Run Chromium OS tests to test core2md. Review URL: http://breakpad.appspot.com/343001 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@905 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Skip ElfCoreDumpTest.ValidCoreFile test if no core dump is generated.benchan@chromium.org2012-01-112-11/+43
| | | | | | | | | | | | | | | CrashGenerator::CreateChildCrash() may have some flakiness. This patch changes ElfCoreDumpTest to temporarily skip the ValidCoreFile test if no core dump is generated by CrashGenerator::CreateChildCrash(), but print out the error message to help debug the flakiness.

* Refactor LinuxDumper and MinidumpWriter.benchan@chromium.org2012-01-112-1/+18
| | | | | | | | | | | | | | | | | | | | | | | 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 two convenient methods, back() and empty(), to the wasteful_vector class. 2. Refactor the LinuxDumper class such that it can later be splitted into a base class and two derived classes, one uses the current ptrace implementation and one uses a core file. 3. Refactor the MinidumpWriter class such that it can later use different derived implementations of LinuxDumper. 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.

* Add utilities for processing Linux core dump files.benchan@chromium.org2012-01-079-26/+1039
| | | | | | | | | | | | | | | | | | | | | 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. 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.

* Replace MMappedRange with MinidumpMemoryRange.benchan@chromium.org2011-12-211-6/+0
| | | | | | | | | | | | | | | | | | | | | | | 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. All unit tests pass. 4. Run minidump-2-core to covnert a minidump file to a core file.

* Replace readlink calls with a safer version that guarantees NULL-termination.benchan@chromium.org2011-12-214-3/+210
| | | | | | | | | | | | | | | | | | | | | 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. 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. Run minidump-2-core to covnert a minidump file to a core file.

| | | | | | | | | | | | | | | | | | | | | | 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 MemoryRange class for encapsulating and checking read access to a contiguous range of memory. 2.

* Wean Mac Breakpad off of its OpenSSL libcrypto dependency.mark@chromium.org2011-07-273-49/+14
| | | | | | | | | | | | | | | | | | This libcrypto dependency sucks. Linking against OpenSSL is sort of broken in certain Mac OS X SDKs. libcrypto was only being used to provide an MD5 implementation. Breakpad already has its own MD5 implementation, so just use that instead. To be perfectly honest, on modern systems, nothing should be making MD5 hashes of modules anyway, because everything has an embedded LC_UUID. The project file changes just remove libcrypto and add md5.c as needed. A bonus (and untested) fix for on_demand_symbol_supplier.mm is included to account for changes in r794.
