* Add optional field indicating multiple symbols at an addressMike Wittman2017-11-291-8/+12
| | | | | | | | | | | | | | | | | | 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.

* Adding stricter validation checks to various symbol parser functions.ivan.penkov@gmail.com2013-09-251-0/+58
| | | | | | | | | | | | | More specifically, the validation of the following record types is improved: - FILE records - FUNC records - Line record - PUBLIC records Adding unittests.

* Detect corrupt symbol files during minidump processing. Recover from the ↵ivan.penkov@gmail.com2013-07-111-0/+1
| | | | | | | | | | | | | | | | | | | | | errors and use the good data if possible. More specifically: - Detect corrupt symbols during minidump processing and provide the list of modules with corrupt symbols in the ProcessState. This will allow listing the corrupt symbol files in the final crash report. - Skip and recover from symbol data parse errors - don't give up until 100 parse errors are seen. - In order to recover from '\0' (null terminator) in the middle of a symbol file, a couple of methods have to be updated to require both buffer pointer and length. Previously they required only a buffer pointer (char *) and the size of the buffer was evaluated using strlen which is not reliable when the data is corrupt. Most of the changes are due to these signature updates. - Added and updated unittests. Also, updated minidump_stackwalk to show a WARNING for corrupt symbols. Output looks like this: ...

* Breakpad: Add minidump processor support for DWARF Call Frame Information.jimblandy2010-03-161-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | Add a CFIFrameInfo class (named for symmetry with WindowsFrameInfo) to represent the set of STACK CFI rules in effect at a given instruction, and apply them to a set of register values. Provide a SimpleCFIWalker class template, to allow the essential CFI code to be shared amongst the different architectures. Teach BasicSourceLineResolver to partially parse 'STACK CFI' records, and produce the set of rules in effect at a given instruction on demand, by combining the initial rule set and the appropriate rule deltas in a CFIFrameInfo object. Adapt StackwalkerX86 and StackFrameX86 to retrieve, store, and apply CFI stack walking information. Add validity flags for all the general-purpose registers to StackFrameX86::ContextValidity. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@549 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Issue 49013: Breakpad Processor: Use a separate API to retrieve Windows ↵jimblandy2010-01-111-1/+3
| | | | | | | | | | | | | | | | | | | | stack debugging info. At the moment, FillSourceLineInfo returns Windows DIA-based stack walking data. In addition to being ugly, this makes it difficult to provide access to DWARF CFI-based stack walking data in a symmetrical way. This patch changes FillSourceLineInfo to do the single job its name suggests, and adds a second member function to SourceLineResolverInterface to retrieve Windows DIA stack walking information. A sibling member function will provide access to DWARF CFI stack walking data. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@480 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Breakpad: Don't use the deprecated __gnu_cxx::hash_map container.jimblandy@gmail.com2009-09-031-24/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Modern GNU compilers warn about the #inclusion of <ext/hash_map>; that container is deprecated, and code should use <tr1/unordered_map> instead. However, to stay within the boundaries of C++ '98, it's probably fine just to use plain old std::map. Breakpad uses hash_map in three cases: o The DWARF reader's SectionMap type maps object file section names to data. This map is consulted once per section kind per DWARF compilation unit; it is not performance-critical. o The Mac dump_syms tool uses it to map machine architectures to section maps in Universal binaries. It's hard to imagine there ever being more than two entries in such a map. o The processor's BasicSourceLineResolver uses a hash_map to map file numbers to file names. This is the map that will probably have the most entries, but it's only accessed once per frame, after we've found the frame's line entry. a=jimblandy r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@393 4c0a9323-5329-0410-9bdc-e9ce6186880e
