Hello all,
Let's move our MediaWiki deploy cycle to weekly instead of 2-week. This will also reduce the number of standing deployment windows throughout the week by having those projects/teams simply "ride the MediaWiki train."
== Current situation ==
Right now, a new version of MediaWiki is rolled out to the WMF cluster over a two-week period. You can see the general flow of how it works on this page describing the deploy schedule for the 1.22 release: https://www.mediawiki.org/wiki/MediaWiki_1.22/Roadmap#Schedule_for_the_deplo...
== What are the drawbacks of two-weeks? ==
These are mostly known by everyone so I'll just simply state the most obvious one :-)
It takes up to 2 weeks for new features/bug fixes to be rolled out to the various Wikimedia wikis.
== What would a one-week cycle look like? ==
This has been talked about a bit, including during the last In Town Week for WMF Engineering in late-February. I've coalesced on one proposal at: https://wikitech.wikimedia.org/wiki/Deployments/One_week
This seems like a reasonable approach to me. Please respond here or on the talk page with comments/suggestions/etc.
== Major benefit/goal with one-week cycle ==
Our current list of deployment windows during the week is pretty large, and it is not uncommon for a week to practically fill up with bug fix windows. If we moved to a weekly cycle then more of those bug-fixes could just roll out with the normal MediaWiki deploy.
== Goal Timeline? ==
I would love to get us switched over to a one-week cycle by mid-June.
