Kibana shows ~400 events/day over all wikis with the same users accounting for a good portion of errors. E.g grouping by message (which only varies by user):

I think core should be pretty good now in wmf9/wfm10. I don't plan on improving a random extension that runs into this, though BetaFeatures might be worth a look.

Does this need to be an exception, or would logging it suffice? That would allow grouping on the user IDs.

I am getting this for MLEB 2017-04 on MW 1.27.4 with PHP 7.0

When trying to save a translation I get:

Exception Caught: CAS update failed on user_touched for user ID '255' (read from slave); the version of the user to be saved is older than the current version.

From what I see here I believe patches were added to MW 1.27.0. So basically there is nothing I can do, even if I update to MW 1.27.4 and MLEB 2017.07?

Kghbln added a comment.Apr 13 2018, 3:21 PM

To mitigate the issue I have to go the translation field again, make a trivial change and re-save.

Nikerabbit added a comment.Apr 27 2018, 1:55 PM

It's not clear what is causing it to you. I have updated Translate long ago to avoid causing this kind of issues. But I don't run any 1.27 wikis so it is possible there is still something I might have missed.

Nikerabbit added a comment.Apr 27 2018, 1:57 PM

Specifically, ApiTranslateUser was removed in 35772fb so based on that I would even close this bug because it addressed the original report.

Kghbln added a comment.Apr 27 2018, 2:00 PM

Ok, as soon as 1.31 LTS is out I will also be able to upgrade to compatible versions, i.e. MLEB 2017.07 or later. If there is still trouble I will report back with a new issue. Thanks for your comment.
