Error when moving page: Error: 1305 SAVEPOINT wikimedia_rdbms_atomic1 does not exist (<dbname>.wikiname.ca)
Open, LowPublicBUG REPORT
Actions

Description

Right after moving a page, we consistently get an error for the last two weeks or so. We had not done any updates to MediaWiki in that time frame. MediaWiki 1.33.0 (1e0e638); PHP 7.2.22 (cgi-fcgi); MySQL 5.7.25-log

With debugging enabled, the error is the following:

[Xa9e60Wj@38AAFnvW98AAAAJ] /index.php?title=Special:MovePage&action=submit Wikimedia\Rdbms\DBQueryError from line 1587 of /home/.../wiki.wikiname.ca/includes/libs/rdbms/database/Database.php: A database query error has occurred. Did you forget to run your application's database schema updater after upgrading?
Query: RELEASE SAVEPOINT `wikimedia_rdbms_atomic1`
Function: MovePage::move
Error: 1305 SAVEPOINT wikimedia_rdbms_atomic1 does not exist (<dbname>.wikiname.ca)

At first glance I don't see a code path in MovePage that would cause a problem like this, and the atomic section logic in the rdbms library hasn't to my knowledge had problems like this in Wikimedia production. My first guess would be some extension in your installation is committing the transaction during one of the hooks.

If you can log the DB queries (log channel "DBQuery") for such a request and post the relevant lines here, including the structured logging contexts, that would be helpful. Ideally you'd include only the parts between the relevant SAVEPOINT `wikimedia_rdbms_atomic1` and the RELEASE SAVEPOINT `wikimedia_rdbms_atomic1` resulting in the error, but posting the whole thing would be better than nothing if you're not sure.

Hi, can you please give extra instructions on what you are asking for Anomie? Also please note we are using both Semantic Mediawiki and Cargo. Really appreciate your help. Thanks, Tom

It sounds like this may be due to a problem in SMW or Cargo. If you can reproduce this without those that would help isolate the problem.

We have this error as well on a Mediawiki 1.31.7 installation, when someone tries to upload a new version of an image. You can see the extensions we use on https://wiki.freepascal.org/Special:Version (SMW and Cargo are not in use).

Reopening per last two comments

Since this doesn't appear to be happening on WMF sites, it's unclear what the priority of this ticket should be.

Aklapper added a comment.Jan 16 2021, 9:46 PM

If that's an argument then probably low if it's still in scope of "Platform Team"?
