Breakpad is a library that generates a dump file after a crash on Windows, Linux and Mac. It is used in Firefox and Chrome. This library is very useful when a user experienced a crash but developers cannot reproduce it. A dump file is generated which later is analyzed against build’s symbol file to find a function which caused the crash. In additional the crash reporter will ask a user to send a dump file every time Blender crashes. That way we can provide critical fixes in timely manner.

==Procedure for using breakpad:==

====Builder/Developer====
* Builder creates a “Release with Debug Info” build WITH_BREAKPAD and WITH_CRASHREPORTER
* Builder uploads the build online
* Then builder generate symbol file for compiled build using dump_syms from breakpad tools. (sometimes you must build your own dump_syms on Windows)
<source lang="bash">
***/dump_syms ***/blender.exe > blender.sym

Wait
Move blender.sym to blender.pdb/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX - id inside symbol file
</source>
* Generated symbol file then uploaded to common repository.

====User====
* User downloads and installs the build
* Build crashes
* The crash reporter starts and asks the user to send the dump file
* User can add name, e-mail and description.
* The report is added to the current bug tracker. (We can have separate crash tracker.) http://projects.blender.org/tracker/?func=detail&atid=498&aid=27400&group_id=9
* The report can be moved or assign to anyone as it is our tracker. The problem that is that user is not registered, so he cannot receive automatic follow ups.

====Developer====
* Ideally server would decode dump file
[[File:BlenderCrashReporter.png|thumb|right]]
* For now developer must manually decode dump file using stackwalk. (on Windows Cygwin should be used to compile it)
<source lang="bash">
***/minidump_stackwalk ***/***.dmp /symbols

/symbols is directory with subdirectories that store
all builds' symbol files like:
blender.pdb/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/blender.sym
</source>
* The output will find crash function and also provide additional info.

I already wrote interface for crash reporter on Windows. In addition I wrote a function that sends dump file to the tracker using cURL so it can be reuse on every OS. Crash Reporter doesn’t have Cmake/Scons support yet.
Breakpad in blender’s source code only changes 2 files and adds 2 additional so it would be easy to include in experimental branches. That way crashes would become known much faster.
