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: ...

// fast_source_line_resolver.h: FastSourceLineResolver is derived from
|
|
// SourceLineResolverBase, and is a concrete implementation of
|
|
// SourceLineResolverInterface.
|
|
//
|
|
// FastSourceLineResolver is a sibling class of BasicSourceLineResolver. The
|
|
// difference is FastSourceLineResolver loads a serialized memory chunk of data
|
|
// which can be used directly a Module without parsing or copying of underlying
|
|
// data. Therefore loading a symbol in FastSourceLineResolver is much faster
|
|
// and more memory-efficient than BasicSourceLineResolver.
|
|
//
|
|
// See "source_line_resolver_base.h" and
|
|
// "google_breakpad/source_line_resolver_interface.h" for more reference.
