Revision as of 22:43, 6 August 2020

Notes:
  • Ask for a little more time than what you think you'll need for deployment and testing; you never know what issues may come up and slow you down.
    • Generally, we have found one hour to be a good size for most things.
  • Deployment windows are 'pinned' to the time in San Francisco and thus the UTC time will change due to the United States observance of Daylight Savings Time as appropriate.
  • Backport windows are for pushing out simple and low-risk changes (as assessed by you, backport team, and the Release Engineering Team). They happen on Mondays to Thursdays at:
    • "European Mid-day backport window", 04:00 Pacific
    • "Morning backport window", 11:00 Pacific (except Tuesdays)
    • "Evening backport window", 16:00 Pacific

For detailed instructions on how to actually deploy code to the Wikimedia servers, see How to deploy code.

Deployments

This page tracks upcoming deployments of software to the Wikimedia Foundation servers that host Wikimedia project sites (Wikipedia, Wiktionary, Wikiversity, Wikimedia Commons, etc.).

Cadence
For the core software ("MediaWiki"): The Wikimedia Foundation currently follows a one-week deploy cadence. This means that there is one week between updates to any one Wikimedia project site wiki (excluding urgent fixes, of course).
For other non-core software: Each team is responsible for their own schedule.
Scheduling
You don't need to schedule a deploy window for most changes; they can be deployed using existing Backport windows that are already scheduled several times a week.
To schedule a deploy window, or if you see a potential conflict with your upcoming deployment, please contact the Release Engineering Team on IRC at #wikimedia-releng connect; pinging Greg (greg-g) or Tyler (thcipriani) directly helps.
Inclusion criteria
See the list at /Inclusion criteria for the kinds of changes that require scheduling a new deployment window.
Long running tasks/scripts
While not strictly a deployment, performing long running (>1 hour) tasks (eg: migration scripts) can encounter issues when code is updated while a script is being run. For this reason it is required to add an entry in the calendar for the task with a window that accounts for the anticipated start time and estimated length for the task.
Communicating
  • Every major or new feature deployment should be announced on the Wikimedia blog and/or Tech News (use the "user-notice" tag on Phabricator) and/or global on-wiki delivery. For routine and maintenance deployments, listing your change here is enough.
  • Changes that are liable to affect site performance or infrastructure should be announced on the ops mailing list. This includes anything that alters caching behavior, introduces cookies, substantially increases the static asset payload, or adds new and complicated query patterns.
Something went wrong‽ (see also Incident response)

Near-term

NOTE: You can also subscribe to the "WMF Deployments" google calendar by adding <wikimedia.org_rudis09ii2mm5fk4hgdjeh1u64@group.calendar.google.com>. This does not always get one-off windows that are noted below. This wiki page is the canonical deployment schedule and any differences with the google calendar are to be interpreted as the google calendar being incorrect.
