[12:34:19] <James_F>	 duesen: Is T198558 ready to ship?
[12:34:19] <stashbot>	 T198558: Set testwiki to use the new MCR-only schema - https://phabricator.wikimedia.org/T198558
[12:35:09] <duesen>	 James_F: IMHO it has been for two weeks, but I was on vacation. Still catching up on mail. I have a meeting about this (among other things) in half an hour, let's ee hwo that goes.
[12:35:20] <James_F>	 OK, won't deploy it now for you then. ;-)
[12:35:52] <duesen>	 James_F: poke me again later today or tomorrow if you don't hear anything
[12:47:31] <James_F>	 Kk.
[16:04:17] <duesen>	 James_F: you still there?
[16:09:09] <James_F>	 duesen: Yes.
[16:09:24] <James_F>	 Want to proceed?
[16:14:49] <duesen>	 James_F: yes, please! But we should send a heads up to... uh, whom, exactly?
[16:15:12] <duesen>	 should this just go to wikitech-l?
[16:15:43] <James_F>	 Yes, and ops-l.
[16:18:35] <James_F>	 duesen: Live on mwdebug1001. Want to test?
[16:19:45] <duesen>	 James_F: sure, just a sec
[16:22:15] <duesen>	 James_F: crud. breaks export.
[16:22:18] <duesen>	 that was quick
[16:22:20] <duesen>	 don't deploy
[16:22:33] <James_F>	 OK, will revert.
[16:22:37] <duesen>	 thanks
[16:24:42] <James_F>	 duesen: Prod is clean again.
[16:24:57] <duesen>	 thanks
[16:26:49] <duesen>	 James_F: so, the testwiki revision row with rev_id = 407151 has rev_text_id = 0. 
[16:27:01] <duesen>	 we can still read it fine with the old setting.
[16:27:24] <duesen>	 i wonder how it breaks with the new setting. it shouldn't affect ow we read things.
[16:29:30] <duesen>	 James_F: uh, so Special:Export has been broken on beta for like three weeks, and *nobody* noticed?
[16:29:31] <duesen>	 view-source:https://en.wikipedia.beta.wmflabs.org/wiki/Special:Export/0.42323637011943815
[16:29:52] <duesen>	 crud.-
[16:33:31] <James_F>	 duesen: I mean, I use it about once a year in production…
[16:33:39] <James_F>	 But yeah.
[18:19:21] <anomie>	 Krinkle: I can't see how there would be a bug there unless someone was manually screwing around with their DB at some point. As far as I can tell, MediaWiki has always had either a ug_user_group index or a PK on the same columns, never neither and never both.

[20:51:29] <duesen>	 James_F: let's see if that fixes export on beta :)
[20:54:31] <James_F>	 duesen: Let's hope. :-)
