History of MediaWiki version control

MediaWiki's source code history began in SourceForge's CVS version control system. We started a project there before the names "MediaWiki" or "Wikimedia" were coined, thus the project name is "wikipedia". This project was used to host pre-MediaWiki wiki software (Magnus Manske's "phase 2"), and finally Lee Daniel Crocker's "phase 3" rewrite which came to be known as MediaWiki.

An extended outage of SourceForge's developer CVS service forced our hand to finally go ahead and set up our own source code repository as of April 1, 2006.

A new repository uses Subversion, which is ever so slightly trendier than CVS but provides a pretty similar interface so should not be too disruptive.

Between April 1, 2006 and May 31, 2007, the repository was hosted on Brion's offsite server (http://www.leuksman.com). Between May 31, 2007 and October 23, 2010, the repository was hosted on mayflower, a Wikimedia server in Amsterdam. As of October 23, 2010, the repository is hosted on formey, in the Tampa data center.

In March 2012, conversion of the existing Subversion repository to Git was initiated and completed in the following weeks. Gerrit is used as a code review tool.
