4I've made some custom namespaces and it all works fine.

At the end of the job the updateSearchIndex.php script will give an error

Thanks for the help

Thanks

Did you try running update.php?

Since I'm not proficient with all this, I had to do some searching and came across this. It looks like a lock was put in place (not on temp_rev_comment, though) and were not unlocked before we got to this query.

If you could enable debug logging, we should be able to find out what code performed locks before this. Could you try this and paste the last few SQL queries from the log file?

Hi @MarkAHershberger,

we have exactly the same problem with updateSearchIndex.php resulting in Error: 1100 Table 'temp_rev_comment' was not locked with LOCK TABLES.

The debug output of updateSearchIndex.php is:

Any idea?

Sorry there where two important lines missing in the debug output that are written to the shell only.

The problem is Error: 1100 Table 'temp_rev_comment' was not locked with LOCK TABLES in function MediaWiki\Revision\RevisionStore::fetchRevisionRowFromConds.

Same issue here - temp_rev_comment is causing problems.

Tying to find the problem I extracted the SQL from debug out:

SET group_concat_max_len = 262144, sql_mode = ''

The last request is causing Error: 1100 Table 'temp_rev_comment' was not locked with LOCK TABLES in function MediaWiki\Revision\RevisionStore::fetchRevisionRowFromConds.

Like the thread opener we added a custom namespace too.
