Some of the fields we save might have signed types depending on the
system (e.g. `typedef int pid_t`). Depending on the toolchain, we
can trip -Werror=narrowing failures like:
src/client/linux/minidump_writer/linux_core_dumper.cc:248:66: error:
narrowing conversion of ‘(__pid_t)info->siginfo_t::_sifields.siginfo_t::<anonymous union>::_kill.siginfo_t::<anonymous union>::<anonymous struct>::si_pid’
from ‘__pid_t {aka int}’ to ‘long unsigned int’ inside { } [-Werror=narrowing]
set_crash_exception_info({info->si_pid, info->si_uid});
^^^^^^
src/client/linux/minidump_writer/linux_core_dumper.cc:252:71: error:
narrowing conversion of ‘(int)info->siginfo_t::_sifields.siginfo_t::<anonymous union>::_sigsys.siginfo_t::<anonymous union>::<anonymous struct>::_syscall’
from ‘int’ to ‘long unsigned int’ inside { } [-Werror=narrowing]
set_crash_exception_info({info->si_syscall, info->si_arch});
^^^^^^^^^^
Since the exception info fields are all uint64_t which should be large
enough to handle all the fields in the siginfo_t structure, add casts
for all the assignments to avoid these errors. We have implicit casts
even without them, so we aren't changing behavior.

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.
