Hello. There is a regression problem, that started on this week deployment.
I can see it in group 1 from yesterday evening. I do not file a phabricator
ticket, because there is no algorithm to reproduce the problem.
>From time to time the API post query "mark this revision as read" does not
work. In these times, there is a reproducing algorithm:
1) Open Special:Watchlist.
2) Pick an unread revision.
3) Open the diff to last version, or the view mode of the page.
4) Expected: the revision, and the whole page, should be automatically
marked as read.
5) Refresh the Special:Watchlist.
6) Got: the revision remains bold.
7) Open API query for unread revisions, the relevant one is still there.
8) Try partagraphs 5-7 every 5 seconds.
9) In about twenty minutes the data is updated correctly.
I saw this yesterday at about 19:45 UTC, and it happens again just now.
Thank you.
