core_handler: coredump handler to produce minidump On Linux, it is possible to register a core handler via /proc/sys/kernel/core_pattern. Doing so invokes the core handler when a process crash. The core_handler uses /proc/<pid>/mem to access the process memory. This way it is not necessary to process the full coredump which takes time and consumes memory. In order to profit from this core handler, for example, one can integrate dump_syms into Yocto and generate an archive with the breakpad symbols of all the binaries in the rootfs. Minidumps are especially useful on embedded systems since they are lightweight and provide contextual information.

Breakpad is a set of client and server components which implement a crash-reporting system.
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 fetch
tool from depot_tools to download all the source repos.
fetch breakpad
cd src
Build the source.
./configure && make
You 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.
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.
