Reported here (SRUC), as request is "approved" but nothing happened. (FYI @Superpes15).

I noticed also that a "failed" old rename appear again on Special:GlobalRenameProgress:
Dzoo → DZoo since 8 November 2021.
Related to T219279

This is weird! It seems that the problem is only for the renaming performed via queue.
But I also noticed (maybe?) another strange thing: several users are making multiple requests within a few minutes, if I'm not mistaken they should receive a message that warns them that there is already a request in the queue and they cannot make another one until the first has been processed, but maybe I’m wrong.

I don't think there's connection: T172604: Prevent users to submit multiple rename requests if there are pending requests and https://lists.wikimedia.org/hyperkitty/list/global-renamers@lists.wikimedia.org/thread/U7CGFESFKJHWI7KUOGVJZ6BGUGS7KDFA

Hopefully they can still use their account with old name before this is fixed.

Edit: I just see the link on Alaa's comment so I think they can still use their account.

@Zabe I wonder if this can be caused by https://gerrit.wikimedia.org/r/c/mediawiki/extensions/CentralAuth/+/774972? That could explain the Username@somewiki suffix that we're seeing in the rename logs.

Yes. Btw I am not sure how many requests there are with the rq_wiki value populated. But we probably need to change them back to NULL by hand in order to prevent this from happening for those requests as well.

Suprisingly this doesn't seem to have caused any unattached local accounts, since the renameuser_status protections in LocalRenameJob prevented the actual renames from happening on the wiki where the rename was requested from.

Looks like we had ~50 approved renames that we'll need to manually repeat (I can write a script for that) and a further 20 requests in the queue that we can fix by updating rq_wiki to null.

wikiadmin@10.192.16.104(centralauth)> select rq_status, count(*) from renameuser_queue where /* recent requests only */ rq_id > 90000 and rq_wiki is not null and rq_status != 'rejected' group by rq_status;

| rq_status | count(*) |
