2026 week 38 1.47-wmf.20 Changes wmf/1.47.0-wmf.20

This MediaWiki Train Deployment is scheduled for the week of Monday, September 14th:

Monday September 14thTuesday, September 15thWednesday, September 16thThursday, September 17thFriday
Backports only.Branch wmf.20 and deploy to Group 0 Wikis.Deploy wmf.20 to Group 1 Wikis.Deploy wmf.20 to all Wikis.No deployments on fridays

How this works

  • Any serious bugs affecting wmf.20 should be added as subtasks beneath this one.
  • Any open subtask(s) block the train from moving forward. This means no further deployments until the blockers are resolved.
  • If something is serious enough to warrant a rollback then you should bring it to the attention of deployers on the #wikimedia-operations IRC channel.
  • If you have a risky change in this week's train add a comment to this task using the Risky patch template
  • For more info about deployment blockers, see Holding the train.

Note that T437829: scap backport failed due to expired debian snapshot could make this train rather cumbersome. Edit: May have gotten resolved in the meantime.

Testwiki is still on wmf.19. Something failed?

Aklapper added a comment.Tue, Sep 15, 6:50 AM

Yes, train-presync failed with No space left on device.

jnuche added a comment.Tue, Sep 15, 6:58 AM

After train-presync failed, our image cleanup kicked in and freed up some space. Hopefully that's enough next time a backport or the train runs. We'll find out in a bit:
