This CL makes it possible to skip a dump if the crashing thread doesn't have any pointers to a given module. The concrete use case is WebView where we would like to skip generating microdump output when webview is unreferenced by the stack and thus cannot be responsible for the crash in a way that would be debuggable. The range of interesting addresses is chosen by examining the process mappings to find the one that contains a pointer that is known to be in the right shared object (i.e. an appropriately chosen function pointer) passed from the client. If the extracted stack does not contain a pointer in this range, then we do not generate a microdump. If the stack extraction fails, we still generate a microdump (without a stack).

Getting started (from master)
-
First, download depot_tools and ensure that they’re in your
PATH. -
Create a new directory for checking out the source code (it must be named breakpad).
mkdir breakpad && cd breakpad -
Run the
fetchtool from depot_tools to download all the source repos.fetch breakpad cd src -
Build the source.
./configure && makeYou can also cd to another directory and run configure from there to build outside the source tree.
This will build the processor tools (
src/processor/minidump_stackwalk,src/processor/minidump_dump, etc), and when building on Linux it will also build the client libraries and some tools (src/tools/linux/dump_syms/dump_syms,src/tools/linux/md2core/minidump-2-core, etc). -
Optionally, run tests.
make check -
Optionally, install the built libraries
make install
If you need to reconfigure your build be sure to run make distclean first.
To update an existing checkout to a newer revision, you can
git pull as usual, but then you should run gclient sync to ensure that the
dependent repos are up-to-date.
To request change review
-
Follow the steps above to get the source and build it.
-
Make changes. Build and test your changes. For core code like processor use methods above. For linux/mac/windows, there are test targets in each project file.
-
Commit your changes to your local repo and upload them to the server. http://dev.chromium.org/developers/contributing-code e.g.
git commit ... && git cl upload ...You will be prompted for credential and a description. -
At https://chromium-review.googlesource.com/ you'll find your issue listed; click on it, then “Add reviewer”, and enter in the code reviewer. Depending on your settings, you may not see an email, but the reviewer has been notified with google-breakpad-dev@googlegroups.com always CC’d.
