Now this is exciting news: MySQL is now using Bazaar and Launchpad for their source code! Both the main MySQL server code and the code for many ancilliary projects have been converted to Bazaar, and are published on Launchpad.

Bazaar is a distributed version control system that Just Works and adapts to the workflows you want to use. Bazaar is a GNU project, and Canonical provides commercial support and custom development.

Launchpad is a next generation project hosting and collaboration system, and we’re delighted that MySQL has chosen to host Bazaar branches of their code on Launchpad. This means that anyone can now publish their own branches of MySQL, with work in progress, fixes, enhancements, or my personal favorite - crazy experimental features! This makes it much easier to collaborate with other developers both inside and outside of MySQL.

MySQL has a very large code base, and a long history going back at least 8 years. Since early 2005, I’ve been working on getting the MySQL source code converted to a Free version control system that would work well for hundreds of developers working across dozens of countries, and it’s such a great feeling to see the results available to the public! In 2006, we started looking at Bazaar, and in recent months many engineers have worked hard to do conversions of all the different releases of MySQL. The Bazaar development team was able to add features to Bazaar specifically to enable the best possible history conversion with no data loss(per-file comments), and work with the Launchpad team to add features to make it much easier to host projects of this size. We’re already seeing a strong development community forming, with a variety of experimental branches showing up. I was also very pleased to see how easy it was for MySQL developers to write plugins to Bazaar to integrate with their custom continuous integration and bugtracking systems.
