@bd808, it doesn't seem like the actual DB error is available on logstash, just that there *was* a DB error. Am I missing something?

The same happens when I try to log into newly created account on Beta (both created in the web UI, or created with createAndPromote.php). The one below is from:

mwscript createAndPromote.php --wiki=enwiki 'Flow test mover 2' 'M81gjn82lJSLI'

Username: Flow test mover 2
Password: M81gjn82lJSLI

However, I can still log into Mattflaschen.

One more thing to add:
The error message on Special:CreateAccount page for attempting to create an account for an existing user will expose HTML markup:

The requested username is already taken in the <a href="http://meta.wikimedia.org/wiki/Help:Unified_login">unified login system</a>. Please choose a different name.

However, it happens only with usernames that displayed ' Fatal exception of type "DBQueryError" ' (with status code: 500) upon creation; old username are fine.

Apparently it's in the message field, but truncated. I noticed that it is somewhere else more readable, https://logstash-beta.wmflabs.org/app/kibana#/doc/logstash-*/logstash-2016.10.14/mediawiki?id=AVfA_rxYYZVhfGLdiMRW&_g=(refreshInterval:(display:Off,pause:!f,value:0),time:(from:now-15m,mode:quick,to:now)) . The latter has two relevant fields, error and sql1line, that together have everything.

It's also on fluorine now.

The lu_local_id stuff is new code CentralAuth from @Niharika that was merged yesterday. Looks like nobody has applied the database migration for it to the beta cluster. CA's migrations aren't done by update.php so it needs to be done manually.

Yeah, T141951: Add local_user_id and global_user_id fields to localuser table in centralauth database says it has been applied on Beta already. Looking into it now.

I'm fairly sure I applied the database changes on the Beta Cluster, but maybe I did it wrong. @Mattflaschen-WMF, @bd808: Can you explain the steps that you took to apply the db patch on the Beta Cluster so I can be sure to do it correctly next time.

• Mattflaschen-WMF added a comment.EditedOct 15 2016, 1:15 AM

There were some problems with the way we did it this time (not the below).

But, a correct version of what we/I did this time:

  1. ssh deployment-tin.eqiad.wmflabs
  2. sql --write centralauth
  3. <Paste in SQL>

I'm pretty sure you can also pipe it to the same command, but I pasted it this time.

sql --write centralauth

ensures you are connecting to the master (the schema change will be replicated to the replicas automatically).

kaldari added a comment.Oct 15 2016, 8:18 AM

That's the same as what I did, except I didn't use "--write". Maybe it didn't get applied to the master somehow.

bd808 reassigned this task from bd808 to • Mattflaschen-WMF.

New account creation on beta cluster wikis seems to be working again after @Mattflaschen-WMF's proper application of the patch to the master db and the subsequent fix of restarting the replication process that had died because of my patch to the wrong db.
