* Breakpad: Add minidump processor support for DWARF Call Frame Information.jimblandy2010-03-161-3/+68
| | | | | | | | | | | | | | | | | | | | | | | | 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
* Breakpad: Update copyright notice years on all files changed in 2010.jimblandy2010-02-091-1/+1
| | | | | | | | | | We've gotten mixed advice from the lawyery types about whether this matters. But it's easy enough to do. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@517 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad processor: Segregate STACK WIN vs. traditional stack walking.jimblandy2010-02-051-168/+227
| | | | | | | | | | | | | This patch moves the code for finding caller frames using STACK WIN data and the code to do so using the traditional frame layout (%ebp points at saved %ebp, pushed just after return address) into their own functions. In addition to making things a little clearer, this is preparation for adding support for STACK CFI records into the mix. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@512 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad x86 Stack Walker: Pass "out" parameters by address, not reference.jimblandy2010-02-051-6/+6
| | | | | | | | | | | | The Google C++ Style Guide requires all parameters passed by reference to be labeled 'const', and says that pointers should be used for output arguments. This patch brings google_breakpad::StackwalkerX86 into line. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@510 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad processor: Save Windows unwinding data earlier in x86 walker.jimblandy2010-02-051-3/+4
| | | | | | | | | | | | | | | | | | | At the moment, StackwalkerX86::GetCallerFrame doesn't save the WindowsFrameInfo that it finds for a frame unless it successfully constructs the caller frame. This means that the windows_frame_info field of the last frame on the stack is left unset, even when that frame does have windows unwinding information. This is not user-visible behavior, so it doesn't matter, but it is a blemish on the interface, and unit tests (added in a later patch) expect it. This patch saves the information in the frame as soon as we find it. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@508 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Breakpad processor: Don't pass Windows stack walking information to all walkers.jimblandy2010-01-141-9/+21
| | | | | | | | | | | | | | | | | | | | | At the moment, the StackWalker GetCallerFrame member function expects a vector of WindowsFrameInfo structures, even though WindowsFrameInfo is only used or useful on one one implementation (StackWalkerX86). This patch changes StackWalker::GetCallerFrame to no longer expect the WindowsFrameInfo structures, and changes all implementations to match. In particular, StackWalkerX86 is changed to find the WindowsFrameInfo data itself, and store a pointer to whatever it got in the StackFrame object itself (which is really a StackFrameX86). To allow GetCallerFrame implementations to look up stack walking data, StackWalker::resolver_ needs to be made protected, not private. a=jimblandy, r=mmentovai git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@491 4c0a9323-5329-0410-9bdc-e9ce6186880e
* Issue 49012: Breakpad Processor: Rename 'StackFrameInfo' structure to ↵jimblandy2009-12-231-8/+8
| | | | | | | | | | | | | | | 'WindowsFrameInfo'. Also, rename stack_frame_info.h to windows_frame_info.h. If it seems odd to have functions like FillSourceLineInfo returning Windows-specific data structures... well, it is!

* Module API (#32). r=waylonis, brynermmentovai2006-12-051-2/+2
| | | | | | | | | | | | | | | | | | | - 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

| | | | | | | | | | | | | | | | | | | | | | | - minidump_stackwalk is now much more useful as a debugging tool and even as a standalone tool. - Reimplementation of minidump_stackwalk around MinidumpProcessor. - minidump_stackwalk displays all pertinent information returned by MinidumpProcessor in the ProcessState. - New PathnameStripper::File static utility method to display only the leaf file name in a pathname, cleaning up minidump_stackwalk's output. - New SimpleSymbolSupplier class, which implements a simple filesystem-based symbol supplier compatible with the layout used by Microsoft Symbol Server and its client cache. - minidump_stackwalk now accepts an optional second argument, a pathname to use as a symbol directory for a SimpleSymbolSupplier. - Updated test data to be compatible with SimpleSymbolSupplier, and added test data for kernel32.pdb.
