* Don't bail if a thread's stack pointer is invalidmkrebs@chromium.org2012-10-081-0/+4
| | | | | | | | | | | | | | Currently, if a thread's stack pointer is not within a valid memory page, the minidump writing will fail with an error. This change allows an invalid stack pointer by simply setting the memory size to zero in the minidump. The processing code already checks for the size being zero, although it currently just gives an error (see https://breakpad.appspot.com/413002/).

* Fix test addresses to use uintptr_t instead of u_int64_t.benchan@chromium.org2012-01-271-1/+1
| | | | | | | | | | | | | | | | 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.org2012-01-191-0/+430
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
