[21:41:29] <Remilia>	 I'm getting some really strange behaviour after 1.46 upgrade: the wiki does not respect MediaWiki:Mainpage until I purge cache, then it does, but only for a short while...
[21:44:59] <Remilia>	 it does not respect MediaWiki:Sidebar either…
[21:47:32] <Remilia>	 and only happens to one installation
[21:57:49] <andre>	 Remilia: what does "respect" mean? what *does* happen?
[21:58:19] <Remilia>	 andre: it opens Main_Page instead of what is expected, and shows the default Sidebar menu
[21:58:31] <moonmoon>	 I'm suspecting CDN or serverside load balancer caches in front of the wiki
[21:58:57] <Remilia>	 moonmoon: there is only a single varnish there
[21:59:18] <Remilia>	 I restarted it to be sure
[22:00:01] <Remilia>	 when I perform Purge on MediaWiki:Mainpage, it works, but only for me as the logged in user, and only for some relatively short while
[22:00:08] <Remilia>	 same with Sidebar
[22:05:45] <Remilia>	 moonmoon: hmm it might be varnish indeed, but I have no idea why this happens (if I tell haproxy to bypass it, stuff starts working)
[22:14:33] <Remilia>	 moonmoon: what really confuses me is that this happened after upgrade to 1.46, it was perfectly fine before, and I rebooted the machine later for OS upgrade
[22:15:03] <Remilia>	 and also the fact that only one wiki is affected out of 5
[22:15:16] <Reedy>	 1.46 does contain a lot of changes from 1.45
[22:15:24] <Reedy>	 It's possible it has bugs
[22:15:35] <Reedy>	 It's possible those bugs have been fixed in master and no one knew to backport
[22:23:52] <Remilia>	 hmm no, removing reverse proxy does not help, just alleviates the problem a tiny bit as purge affects everyone
[22:31:13] * Remilia goes to roll back to 1.44 and see if that helps
[22:33:45] <Remilia>	 worked, will see if I can set up a clone to diagnose this tomorrow
[22:35:14] <Remilia>	 1.43 upgraded to 1.46 seemingly fine, 1.44 did not, weird
