Rob Lanphier proposed a draft plan on the wikitech-l mailing list.

Rob Lanphier proposed a draft plan to proceed to a migration to git over the following months, and got a positive response from developers.

Chad Horohoe started to prepare for the migration to git; he wrote a script to compare LDAP accounts to the information stored in Code review, and prepared for conversion tests from the current Subversion repository. An important step in the conversion is having names and email addresses for all committers, since neither Git nor Gerrit function well without them. As of this writing, 26 committers do not have any contact information, and 25 have a name but no e-mail address. Please help by filling in the names of committers you know.

Chad is down to one last email address of a committer to confirm, then a full import will happen. He has already started a partial import (up to r100000), and will do the complete import once that is done.

Chad Horohoe got a lot of help from the community on identifying unknown committers; user mapping is now complete. Gitorious was installed on a virtual machine, and a test git conversion of the MediaWiki code repository is now imminent. Meanwhile, there have also been discussions about e-mail aliases for LDAP users, to avoid disclosing private e-mail addresses. Chad and Brion Vibber worked on changes to the development workflow introduced by the move to git (e.g., when continuous integration tests get run).

Have currently working conversion of MediaWiki core in Gerrit and are sorting out the permission model. We're having two meetings this week (both on Dec. 19th) to help hammer out the details. Join us in #wikimedia-dev!

The rules to convert  have been finished and a [//gerrit.wikimedia.org/r/gitweb?p=test/mediawiki/core.git;a=summary test repository] is now available. Chad Horohoe is now working on convert rules for extensions, and on user permissions.

2012-01-31
The MediaWiki  repository has been successfully converted with branches. Another upcoming test repository will include release tags, and extension projects will be set up shortly.

<section begin=2012-02-23/>The migration of MediaWiki core and of extensions used on WMF sites is now scheduled for the first weekend in March (3 March 2012). Sumana Harihareswara and Chad Horohoe wrote a blog entry to answer some common questions about the migration. Starting on 24 February WMF Engineering will start making strong efforts to train the development community in using Git and Gerrit, including screensharing trainings.<section end=2012-02-23/>

<section begin=2012-02-29/>The migration of MediaWiki core and of extensions used on WMF sites is now tentatively scheduled for 21 March 2012. Sumana Harihareswara and Chad Horohoe wrote a blog entry to answer some common questions about the migration. WMF Engineering is making strong efforts to train the development community in using Git and Gerrit, including documentation and trainings via screensharing on February 27 and 28. We will be moving Gerrit infrastructure to Ashburn, as the Tampa server we're using can't handle the load.<section end=2012-02-29/>

<section begin=2012-03-22/>We've now moved MediaWiki core and WMF-deployed extensions over to Git and Gerrit, and for those directories Subversion is now read-only. We've communicated links and workflow planning, and the new procedure to add and remove people from Gerrit project owner groups.<section end=2012-03-22/>

<section begin=2012-04-13/>MediaWiki core and all WMF-deployed extensions are getting into regular development cycles. The first batch of non-WMF extensions was migrated on 6 April, with only minor issues. Many small issues in Gerrit/Git have been fixed over the past week. Notably, automated localization commits have been fixed and will resume on Monday, April 16. On April 10, we cut the first WMF deployment branch (1.20wmf1) and pushed it to test2.wikipedia.org and mediawiki.org, with success. The priorities for Gerrit are currently fixing our UTF-8 problem, improving Gerrit integration with IRC/e-mails, making project/user information more discoverable, and upgrading Gerrit to 2.3 in the next 2 or 3 weeks.<section end=2012-04-13/>

We've also branched and released 1.20wmf1 to most WMF sites.
