* Add GYP build for the src/tools directory on Mac and Linux.rsesek@chromium.org2014-07-241-0/+83
| | | | | | | | | | | | | | | This GYP-ifies the src/processor and src/common directories on those platforms as well. The Makefile build uses much more granular unittest executables, so the new processor_unittests does not yet link because of multiple main() symbols, but this will be fixed later.

* Chrome on Android now supports loading the shared library directly from the ↵rmcilroy@chromium.org2014-07-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | APK file. This patch makes two changes to breakpad to enable crash reporting to work correctly when the library is inside another file (an archive): - Do not filter mappings which map an executable at a non-zero offset. - If such an executable is mapped look in the ELF information for the shared object name and use that name in the minidump. Note this change doesn't care about the archive format and isn't Android specific (though loading the shared library this way is currently only done on Android).

* minidump-2-core: Allow user to override shared lib basedir.thestig@chromium.org2014-04-181-5/+19
| | | | | | | | | | | | | | | | | | | | | | | This CL introduces "--sobasedir" command-line option to minidump-2-core. By default, paths to shared lib files included in generated core file are formatted as "/var/lib/breakpad/[GUID]libFoobar.so". By using "--sobasedir", this will be "[user-supplied-path]libFoobar.so". This option can be used to ease debugging minidump files from developer's local builds. By specifying "minidump-2-core --sobasedir `pwd`/out/Debug/lib/ foobar.mdmp", user can load the generated core file in gdb without setting up the symlinks for "/var/lib/breakpad".

* Implement core dump to minidump conversion.benchan@chromium.org2012-01-191-0/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Replace MMappedRange with MinidumpMemoryRange.benchan@chromium.org2011-12-213-114/+399
| | | | | | | | | | | | | | | | | | | | | | | 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 the other classes which receive debugging data from some sort of parser and use it to populate a Module have names ending in "ToModule": DwarfCUToModule, DwarfCFIToModule. Also, DumpStabsHandler doesn't actually dump anything. This patch renames the DumpStabsHandler class to StabsToModule, which is more consistent and descriptive. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@584 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux dumper: Make StabsReader independent of endianness and word size.jimblandy2010-05-051-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | StabsReader simply applies a reinterpret_cast to treat the stab entry data as an array of 'struct nlist' structures, making the parser specific on the host endianness, word size, and alignment rules. On Mac OS X, a single fat binary file may contain object files of different ABIs, of which the user chooses one at run time. This patch changes the parser to read the data using the google_breakpad:: ByteCursor class, which can handle different endiannesses and word sizes. The StabsReader constructor now takes arguments indicating the endianness of the data and the size of each entry's value field. The patch changes src/common/linux/dump_symbols.cc to pass the new argument. This patch changes the StabsReader unit tests to use the google_breakpad:: TestAssembler classes to generate test data, rather than reading it from a file. This makes it easy to generate test data in various endiannesses and word sizes. It also adds tests for the new parser behaviors. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@583 4c0a9323-5329-0410-9bdc-e9ce6186880e

| | | | | | | | | | The ByteBuffer and ByteCursor classes are utility classes for reading binary files, handling endianness and word size issues in a portable way. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@582 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad test support: Move test_assembler.{h,cc} from src/processor to ↵jimblandy2010-04-271-3/+2
| | | | | | | | | | | | | | src/common. The google_breakpad::TestAssembler classes are used in both the processor's and the Linux dumper's test suites, and will soon be used in the Mac dumper's tests as well. This patch moves their source files from src/processor to src/common. a=jimblandy, r=thestig git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@574 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Breakpad symbol dumper: Move Linux dumping classes into src/common.jimblandy2010-04-051-3/+5
| | | | | | | | | | | The Linux symbol dumper's classes are reasonably portable, and should be usable for the Mac dumper as well. Move them to src/common, along with their unit tests. Update #include directives and Makefile. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@567 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux dumper: Generate make dependencies on header files automatically.jimblandy2010-04-011-5/+9
| | | | | | | | | | | | | The Linux dumper's Makefile doesn't record the object files' dependence on header files at all, just because I was too lazy to write them out and knew I would forget to keep them up to date anyway. But I've wasted too much time tracking down mysterious segmentation faults and other problems after changing header files, and I know it's wasted others' time, too. a=jimblandy, r=nealsid,dmuir git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@563 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad DWARF parser: Add support for parsing .eh_frame encoded pointers.jimblandy2010-03-161-0/+21
| | | | | | | | | | | | The Linux C++ exception handling data format (.eh_frame) can specify a number of different encodings for the addresses it contains. This patch extends dwarf2reader::ByteReader to read pointers encoded in these ways. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@551 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad Linux dumper: Add support for dumping DWARF CFI as STACK CFI records.jimblandy2010-03-161-1/+54
| | | | | | | | | | | | | | | | | | | | | | | Define a new DWARF parser class, dwarf2reader::CallFrameInfo. Extend google_breakpad::Module to store and write out 'STACK CFI' records. Define a new google_breakpad::DwarfCFIToModule class, to accept DWARF CFI data from the parser and populate a Module with the equivalent STACK CFI records. Extend the Linux symbol dumping tool, dump_syms, to use dwarf2reader::CallFrameInfo, google_breakpad::DwarfCFIToModule, and google_breakpad::Module to extract DWARF CFI from the executable or shared library files and write it to the Breakpad symbol file. Define CFISection, a new class derived from TestAssembler::Section, for use in creating DWARF CFI data for test cases. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@550 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Linux DWARF reader: Follow DW_AT_abstract_origin links to find function names.jimblandy2010-02-101-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Without this patch, debugging information like the following will produce FUNC records with no names, because the dumper (correctly) ignores the DW_TAG_subprogram DIEs that lack DW_AT_low_pc/DW_AT_high_pc attributes, but won't follow the DW_AT_abstract_origin link from the DIE that does have code addresses to find its name. <1><168>: Abbrev Number: 5 (DW_TAG_class_type) <169> DW_AT_name : Foo <2><183>: Abbrev Number: 7 (DW_TAG_subprogram) <185> DW_AT_name : Foo <18b> DW_AT_declaration : 1 <1><1b7>: Abbrev Number: 12 (DW_TAG_subprogram) <1b8> DW_AT_specification: <0x183> <1bc> DW_AT_inline : 2 (declared as inline but ignored) <1><1dc>: Abbrev Number: 16 (DW_TAG_subprogram) <1dd> DW_AT_abstract_origin: <0x1b7> <1e1> DW_AT_low_pc : 0x8048578 <1e5> DW_AT_high_pc : 0x8048588 a=dmuir, r=jimblandy git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@520 4c0a9323-5329-0410-9bdc-e9ce6186880e
