* Fix test addresses to use uintptr_t instead of u_int64_t.benchan@chromium.org2012-01-273-4/+4
| | | | | | | | | | | | | | | | When a variable is used to set (and lookup) MappingInfo's "start_addr" field, it needs to match types -- which is "uintptr_t". When Chrome OS updated the 'make' that's used for building, the 32-bit "char *" had sign-extended when cast up to a u_int64_t -- maybe because pointers were unsigned before and then changed to be signed -- and that caused the address lookup to fail.

* Implement core dump to minidump conversion.benchan@chromium.org2012-01-1910-356/+1005
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Refactor LinuxDumper and MinidumpWriter.benchan@chromium.org2012-01-114-88/+128
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | 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.
