* fix pointer style to match the style guideMike Frysinger2020-07-151-3/+3
| | | | | | | | | | We do this in a lot of places, but we're inconsistent. Normalize the code to the Google C++ style guide.

* Fix 'debug_file' in PESourceLineWriter.Nelson Billing2019-06-191-1/+1
| | | | | | | | | | | - Add a #define to testing.gyp to avoid warnings about TR1 deprecation. - PESourceLineWriter now reads debug_file from CodeView record instead of using code_file value. - Updated PE-only MD reading unit test.

* Enable PE-only metadata dumping for 64bit (aka. PE32+ format) PEs files.Nelson Billing2019-06-122-0/+214
| | | | | | | | | | | | | | | | | - Implement in common_windows_lib-- added class "PESourceLineWriter". - Add command-line switch to tell dump_syms to use PESourceLineWriter. Symbol data created this way will contain information to correlate the module with ones found in minidumps, along with frame info that allows much higher quality stack-walking in those minidumps. - Significant refactor of PDBSourceLineWriter-- all code concerned with extracting metadata from PE files has been moved into utility functions. This is to allow sharing of this functionality with newly- added PESourceLineWriter. - Added a unit test to dump_syms for the PE-only scenario.

* Fix dump_syms unit tests on Windows.Nelson Billing2019-03-186-317/+317
| | | | | | | | | | | | | | | - Baselines appeared to be stale. dump_syms now prints FUNC entries with the full function signature, whereas the baselines only contained the function name. The current state of the symbol file docs (https://chromium.googlesource.com/breakpad/breakpad/+/refs/heads/master/docs/symbol_files.md) seem to agree with the new FUNC entries rather than the old ones. Example of a name given in current docs: "nsQueryInterfaceWithError::operator()(nsID const&, void**) const".

* Add optional field indicating multiple symbols at an addressMike Wittman2017-11-291-1/+1
| | | | | | | | | | | | | | | | | | Adds an optional 'm' as the first field in FUNCTION and PUBLIC records to indicate that the address corresponds to more than one symbol. Controls this by a command line flag for now to give symbol file users a chance to update. Also reduces the number of IDiaSymbols retained in memory to one per address. This reduces memory consumption by 8% when processing chrome.dll.pdb. Updates the processor to parse the new optional field.

Update .sym file. * Stop collecting stderr from dump_syms. Future work: perhaps it's worth collecting stderr to compare with a different file to verify that "Couldn't locate EXE or DLL file" is output when expected? * Regenerate testdata for test #5 (dump_syms_regtest64), which currently does not pass, seemingly due a mis-match in the PDB age between the .pdb file and the .sym file.

| | | | | | | | | | | | | | findChildren DIA function. This has a substantial performance improvement over using the getSymbolsByAddr iterator, especially on certain 64bit DLLS. e.g. Time to process chrome_child.dll drops from 51 minutes to 21 secs. Note: new test data looks different because the ordering of lines is no longer by memory address. This does not affect processing. The test data has been manually compared to old data and matches (except additional PUBLIC symbols). Also, INFO lines are omitted because the source executable files are not checked in, so they are unavailable.

* Add explicit OMAP support to dump_syms.chrisha@chromium.org2013-05-0111-14099/+18183
| | | | | | | | | | | | | | This CL adds new utilities to common/windows for handling OMAP information in PDB files. It then augments PdbSourceLineWriter with explicit OMAP knowledge so that symbolization will proceed more cleanly for images whose PDB files contain OMAP information. This makes breakpad handle OMAPped symbol files as cleanly as WinDbg.
