Seems to be related to the Actor feature T188327

Chances are this doesn't need to block wmf.6. More likely it's due to rOMWCe23c7c4c4158: Set ActorTableSchemaMigrationStage => write-both/read-old on group 1.

i.e. rolling back to wmf.4 probably wouldn't fix it, while reverting e23c7c4c4 would. But let me try to track down the problem first.

It looks like all of these are due to Wikibase\Client\Changes\InjectRCRecordsJob. I suspect T183019: Wikibase must not insert local recentchanges entries for nonexistent local users (days: 5) somehow got accidentally regressed.

Mentioned in SAL (#wikimedia-operations) [2018-11-29T15:32:42Z] <anomie@mwmaint1002> Running Wikibase/populateSitesTable.php and cleanupUsersWithNoId.php on several other wiktionaries for T210732

These started at 2018-11-26T18:35:09, consistent with the deployment of e23c7c4c4 at 2018-11-26T15:24 (and not consistent with the deployment of wmf.6).

It was affecting the following sites: arwiktionary brwiktionary cswiktionary elwiktionary eowiktionary eswiktionary euwiktionary huwiktionary itwiktionary jawiktionary kowiktionary ltwiktionary nlwiktionary ptwiktionary rowiktionary ruwiktionary svwiktionary thwiktionary trwiktionary zhwiktionary. It looks like there are others that might be affected too, I'm running a check across all wikis for recentchanges rows that are a sign of this issue.

If this starts happening on more wikis, try running the following maintenance scripts:

mwscript extensions/Wikibase/lib/maintenance/populateSitesTable.php --wiki=$WIKI --force-protocol https
mwscript maintenance/cleanupUsersWithNoId.php --wiki=$WIKI --table recentchanges --force --prefix wikidata

This should be resolved now. If more wikis start having the error, try running the maintenance described in T210732#4785479.
