* Provide a mechanism for SymbolSuppliers to interrupt processing (#93)bryner2006-12-088-79/+136

* Allow exception handler callbacks more flexibility (#81). r=brynermmentovai2006-12-077-21485/+21961
| | | | | | | | | | | | | | | | | | | | | - Provide an optional filter callback that gets triggered before attempting to write a dump, to give client code a chance to refuse handling early in the process. - Allow exceptions that are unhandled by Airbag (due to filter callback or dump callback return value, or failure to write a dump) to be passed to the previous handler or to the system. - In order to pass exceptions unhandled by the topmost Airbag handler to lower handlers, fix up the stacking of ExceptionHandler objects, and give each ExceptionHandler object its own thread (like the Mac implementation) to avoid deadlock. - Provide a dump_path argument to callbacks, as requested by developers and already implemented in the Mac handler. - Avoid calling c_str in exception handler code (#90). http://groups.google.com/group/airbag-dev/browse_thread/thread/4771825ced38a84c git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@79 4c0a9323-5329-0410-9bdc-e9ce6186880e

* Module API (#32). r=waylonis, brynermmentovai2006-12-0524-255/+1029
| | | | | | | | | | | | | | | | | | | - Introduces a standard API for dealing with modules. MinidumpModule is now a concrete implementation of this API. Code may interact with single modules using the CodeModule interface, and collections of modules using its container, the CodeModules interface. - CodeModule is used directly by SymbolSupplier implementations and SourceLineResolver. Reliance on the specific implementation in MinidumpModule has been eliminated. - Module lists are now added to ProcessState objects. Module references in each stack frame are now pointers to objects in these module lists. - The sample minidump_stackwalk tool prints the module list after printing all threads' stacks. http://groups.google.com/group/airbag-dev/browse_frm/thread/a9c0550edde54cf8 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@74 4c0a9323-5329-0410-9bdc-e9ce6186880e

FillSourceLineInfo passes the StackFrameInfo back to the caller. - The base Stackwalker makes StackFrameInfo data available to subclasses during stackwalking, but does not use this information directly itself. Stackwalkers may access stack_frame_info_ for enhanced stackwalking (this will be part 4). - New test data for the updated dumped-symbol format http://groups.google.com/group/airbag-dev/browse_thread/thread/735f191c9a1a1de4 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@38 4c0a9323-5329-0410-9bdc-e9ce6186880e
