[17:10:38] https://integration.wikimedia.org/zuul/?q=533772 [17:15:33] Krinkle: yeah there are multiple problems in the current ci config :-\\ [17:15:54] such as running tests for php 7.0 / 7.1 / 7.3 on Wikibase which is a high traffic repo [17:15:56] and [17:16:20] the second is that we run way more selenium tests nowadays so that pills up a lot (it is like half the time of the build now) [17:16:52] so whenever a few Wikibase changes are +2ed ... all executors ends up being busy for a while [17:17:24] hashar: qunit, npm-test and wdio can be limited to one flavour (e.g. php72) [17:17:32] maybe even a separate job that doesn't do any phpunit [17:17:39] probably yeah [17:18:07] we also have one that only does npm-test which we might not need. Obsolete with the quibble job that would do npm-test + qunit + wdio [17:19:29] but anyway, I want to first complete that split of the test/gate and submit pipelines to have them on a per branch basis [17:19:52] which will simplify the config a lot (way less skip-if and branch filters since they would only be at the pipeline level) [17:20:15] and I guess I gotta get that Docker package uploaded for Stretch to be able to migrate instances to Stretch and to instances will less RAM [17:20:29] the pipeline split, I think I will finish it tomorrow [17:21:30] I am off for dinner *wave* [18:00:07] I just was going to ask for ideas why CI is super busy those days, and read this conversation between hashar and Krinkle [18:00:25] I'm trying to get a +2 at https://gerrit.wikimedia.org/r/c/mediawiki/extensions/Wikibase/+/533907 from jenkins [18:00:35] (that's for an UBN, T231276) [18:00:36] T231276: RevisionBasedEntityLookup.php: Revision 363395998 belongs to M77688146 instead of expected M81625979 - https://phabricator.wikimedia.org/T231276 [18:01:14] yeah simple version is: too much stuff added to jobs without thinking about consequences and no oversight or leader that keeps an eye on overall run time to put breaks on it when it gets too high. [18:01:29] as the old saying goes: if everyone together is repsonsible, that means nobody is responsible. [18:02:14] that's why I'm for the interpration of "deployers are _solely_ responsible for state of config", since only them can edit it, rather than community and deployers sharing the responsibility [18:02:32] anyway, since I'm not sure if jenkins didn't requeue tests after updating, while test was running for a manual recheck, I did recheck [18:02:41] and then noticed...it is cluttered [18:02:58] current wait time is about 30-40 minutes before the build starts. [18:03:01] well, moving php7 from test to php should be simple enough Krinkle [18:03:05] then 20min for the result [18:03:07] I'm going to grab a cup of tee then [18:05:41] that's very long [18:05:54] longer even in usual CI terms [18:07:13] Try being up all night baby sitting patches ;) [18:07:30] not tell that to me, please [18:07:43] I did that, few days ago [18:07:53] (somehow) [18:08:07] got to bed at 4am, got up at 7 am [18:08:43] given it's school holiday, most of my time awake is donated to Wikimedia anyway, but that is really extensive even in my standards :D [18:08:59] so, Reedy, while I'm happy to volunteer, I can't do that always ;) [18:09:12] You have no commitments [18:09:21] Just remove the C+2 and go to bed [18:09:30] which? [18:09:30] (if it's mw-config etc) [18:09:55] well it's master [18:10:06] I'm trying to make that patch to stopgap the UBN first [18:10:19] Still... [18:10:25] That seems like it's WMDE's responsibility, not yours [18:10:48] well, does that mean I can't help them? ;) [18:11:03] It doesn't [18:11:04] PROBLEM - Mediawiki Error Rate on graphite-labs is CRITICAL: CRITICAL: 20.00% of data above the critical threshold [10.0] [18:11:13] But similarly, you shouldn't lose excessive sleep over it [18:11:20] agreed [18:11:35] going to bed in a few, it's 8 now [18:12:00] it was one-time incident :P.
