[Engineering] 1.30.0-wmf.9 train halted due to new log messages

Thu Jul 13 18:32:31 UTC 2017

Hello all,

There are a few new log messages that have crept their way into the 
1.30.0-wmf.9 train release currently winding its way down the track - on 
group0 and group1 wikis[0]. I've halted the train for the time being due 
to these new messages[1].

1. T170599[2] - Wikibase: $idSerialization must match /^Q[1-9]\d{0,9}\z/i
2. T170596[3] - Could not acquire lock 'LinksUpdate:job:pageid:xxx'
3. T170597[4] - Wikidata/extensions/Constraints: 
InvalidArgumentException:$itemId must be either ItemId or string

RelEng makes an attempt during train to keep the introduction of new log 
messages per-release to a minimum. Logspam masks real problems and can 
make the job of deployers and developers unpleasant.

Any help or guidance on any of these three tasks would be very much 
appreciated!

Thanks!
