How this works

Any serious bugs affecting wmf.28 should be added as subtasks beneath this one.
- Use this form to create 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.

T260349 has been resolved by merging the necessary patches into Wikibase main. Therefore, I am removing it as a subtask.

1.36.0-wmf.28 is running all wikis.

Notable errors:
T273101: WikiPage related errors. Looks like Daniel Kinzler has started working on this.
T273242: MemcachedPeclBagOStuff...Serialization of 'Closure' is now allowed. Filed not too long ago. No action yet.

T273296 was not able to be resolved in a timely manner so we decided to roll all wikis back to .27.

Note to train conductor: That bug was successfully root-caused, with patch merged to master, and .28 backports proposed.

Go blocked due to the introduction of T254838: Move User::changeableGroups and User::changeableByGroup to UserGroupManager and User::changeable(By)Groups being hard deprecated in the process.

@Urbanecbm has done the rollback:

Will do the 1.36.0-wmf.28 updates today, exact schedule to be determinated.

1.36.0-wmf.28 has reached group 1 an hour or so ago. Thanks @Urbanecm for the backports and the verification!

@hasher et al, after discussion in IRC we release engineering has settled on rolling everything back to .27 and declining this .28 task. I will do the rollback at the next opportunity.

I moved remaining blockers over to the .29 task (T271343).

I will send an email notification too.

dancy closed this task as Declined.Feb 1 2021, 9:23 PM

Rollback to .27 has finished.

Cool thank you for the rollback. I will follow up on T271343 :]
