What tools are available for developing on the MariaDB code?

The code is hosted on Launchpad. You can branch the latest code from there, and you can also push your own changes as a new branch that can be shared with others. The bzr revision control system is used, at least version 1.12 is recommented (old versions are not compatible with the repository format used on the Launchpad MariaDB trees).

Building the code from source is done with standard Unix tools: autotools, Gnu Make, GCC (or other C/C++ compiler on some systems). On Windows, CMake and Visual Studio are used.

The current state of the source with respect to build/test failures can be seen in buildbot.

We are still deciding which bug tracker to select long-term. For now, the one on Launchpad can be used.

For project management, we use Worklog.

The source page has links to instructions on setting up a full development environment, if you are interested.
