Roadmap

Background: In recent years, Wikimedia Foundation's engineering planning has primarily taken place in a combination of internal goals documents and public project-level documentation. The purpose of this page is to establish a practice of sharing holistic engineering goals, initially primarily with a short term horizon, as a public document with open participation.

See also:
 * Product Whitepaper for Wikimedia Foundation product priority justifications; Strategic Plan for long-term WMF  goals, some of which are engineering goals
 * Roadmap/Archive for an earlier effort to create a roadmap more focused on point releases of the MediaWiki software
 * Software deployments schedule

Previous months:
 * /2011/September
 * /2011/October
 * /2011/November
 * /2011/December
 * /2012/January

Item syntax: Examples:
 * Action item
 * [Needs consensus] Deploy unicorns [Brion/Tim]
 * Deploy unicorns [Brion/Tim] [DONE]

Platform / Dev-Ops

 * MediaWiki 1.19/Roadmap
 * Finish code review
 * Cut 1.19 release branch


 * Git conversion
 * Final conversion on core
 * Final conversion on extensions
 * Finish up specific Git management scripts
 * Deployment scripts
 * CI tests get run when a developer submits a change (or maybe when the change is approved -- this is TBD)
 * Jenkins (Testswarm/PHPUnit tests) on git branches
 * documentation tasks
 * some basic pointers for learning about git
 * document the overall dev process (this is in people's heads right now but not on any wiki page)
 * document how, from a technical perspective, git, Gerrit and Jenkins work together
 * document how to use the tools (git-review, Gerrit, Jenkins)

 * Deployment to locke in January


 * Swift
 * 100% deployment for thumbnails [Aaron/Ben/Mark B]
 * BEFORE 1.19 deployment.
