2020 week 38 1.36-wmf.9 Changes wmf/1.36.0-wmf.9

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.9 and deploy to Group 0 Wikis.Deploy wmf.9 to Group 1 Wikis.Deploy wmf.9 to all Wikis.No deployments on fridays

How this works

  • Any serious bugs affecting wmf.9 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.
  • For more info about deployment blockers, see Holding the train.

Wroth noting is that we now have git 2.2.20 on Stretch and git protocol version 2 enabled. That should not affect the train (beside slightly faster git fetches), but might have some unexpected one.

Change 627400 had a related patch set uploaded (by DannyS712; owner: trainbranchbot):
[mediawiki/core@wmf/1.36.0-wmf.9] Branch commit for wmf/1.36.0-wmf.9

Change 627400 merged by jenkins-bot:

Branch cut happened automatically by cron job, I CR+2'd it at 9:34 my time (UTC+3). https://gerrit.wikimedia.org/r/c/mediawiki/core/+/627400

I applied security patches and attempted to deploy to testwikis, around 20 minutes later. That failed (T262900: Rebuilding l10n cache fails for train), because scap failed to build l10n cache. Scap managed to sync to deploy1001, but nowhere else.

Sent a "train status update" email to ops@ and wikitech-l@, but I don't get copies of emails I send to those so I don't know yet if it went through.

The wmf.9 being on deploy1001 only is causing alerts on #wikimedia-operations. Rolling back... fails.

l10n cache missing for 1.36.0-wmf.9: u'/srv/mediawiki-staging/php-1.36.0-wmf.9/cache/l10n/l10n_cache-en.cdb'

Same reason: no l10n cache.

(The uncommitted changes to deploy-promote is because I have a local change to use scap sync instead of scap sync-world.)

@LarsWirzenius one of the revert commit missed a Change-Id because git revert does not seem to trigger the git hook commit-msg which inserts the Change-Id header. I have edited it, you can push for review again ;)

Over to you, Brennen, with my apologies and thanks.

End-of-local-day notes:

  • I fetched (but did not sync out) backports for T258001 to the wmf.9 branch on deploy1001.
  • Earlier I noticed an extraneous /srv/mediawiki-staging/php-1.36.0-wmf.9/php-1.36.0-wmf.8, a symlink to itself. I thought this might be a symptom of some other breakage, but there's nothing obvious. Deleted.

We're now past the deploy cutoff for today, handing back to Lars for the European morning window, assuming a resolution to T262900.

T262900: Rebuilding l10n cache fails for train is supposed to be fixed, though not closed yet. Backported by @hashar. Trying to deploy to testwikis.

LarsWirzenius added a comment.EditedWed, Sep 16, 10:07 AM

This week's train is powered by Assam, Lapsang souchong, and Creme caramel tea, and the official soundtrack is Scooter's "Mind the gap". Just for the record.

Deployment to testwikis worked. Going for group0 now.

We are at group0 now.

Train promoted to group1.

Over to you, with thanks.

End-of-day here, passing back to Lars.

Promoted to group2 about 15 minutes ago. Filed T263128: ResponseException from line 56 of extensions/GeoData/includes/Searcher.php: but not yet as a blocker.

@brennen is taking over for the rest of Thursday. Thanks.
