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.
