#openstack-nova - 2019-09-27
13:51:42 dansmith mriedem: (re: your mention from the meeting yesterday)
13:51:55 openstackgerrit melanie witt proposed openstack/nova master: Reduce scope of 'path' query parameter to noVNC consoles https://review.opendev.org/685194
13:52:22 mriedem dansmith: ack
13:53:11 mriedem lyarwood: if you're about can you hit these? https://review.opendev.org/#/q/project:openstack/nova+branch:stable/stein+status:open+label:Code-Review=2
13:55:13 mriedem dansmith: can you hit https://review.opendev.org/#/c/680871/ and https://review.opendev.org/#/c/676498/ for rocky?
13:55:27 artom mriedem, you saw ya.wang's review on that NUMA fix?
13:55:34 dansmith I've got the rocky set up right now, are those two more important?
13:56:07 mriedem more important?
13:56:28 mriedem the former is a long-standing issue for baremetal instances, the latter is an lxc thing which is low priority
13:56:33 mriedem lxc+py3
13:56:38 mriedem artom: not yet
13:56:41 dansmith mriedem: meaning you pointed me at two rocky reviews, just wondering if I can hit those when I get to them in the rocky queue or if I should do those first for some reason
13:56:42 mriedem artom: does it work?
13:56:48 artom mriedem, yeah, tl;dr, he's +1
13:56:51 mriedem dansmith: oh, they're just ready
13:56:53 dansmith mriedem: or were you just spoon-feeding me?
13:56:54 mriedem meaning already merged in stein
13:57:07 mriedem yes, pureed stable food
13:57:37 mriedem artom: +2
13:57:46 mriedem yaawang: thanks for testing https://review.opendev.org/#/c/684409/
13:57:57 artom yaawang, yep, much appreciated :)
14:05:20 efried stephenfin: done. Do you have any paste savvy?
14:05:35 efried dansmith: or you?
14:05:37 stephenfin very little, unfortunately
14:05:43 dansmith not really, no
14:05:50 dansmith I'm always mystified by that stuff
14:06:12 efried damn and blast
14:07:12 dansmith what is the question?
14:07:16 efried google seems clueless as well
14:07:29 efried dansmith: this https://review.opendev.org/#/c/685181/
14:08:03 dansmith is this a thing we want to do?
14:08:15 efried tldr version discovery endpoints shouldn't require auth, but I don't know how to make /v2.1 use a different paste composite from /v2.1/$everything_else without enumerating $everything_else
14:08:25 dansmith like, should I be able to probe vexxhost to figure out what version it's running with no credentials?
14:08:31 efried absolutely
14:08:49 efried the root discovery documents (everywhere) are already unauth'd
14:09:22 efried but at least nova, cinder, and neutron are broken in this same way, requiring auth for the versioned discovery docs (which are simply subsets of the root one)
14:09:35 dansmith sure, but the microversion available indicates what level of code is running
14:10:31 efried The version discovery process that ksa uses (currently) assumes you can probe both the root and the versioned discovery URIs without auth.
14:11:27 dansmith ack, it just seems like getting into actual details of the system should require auth, but I'm not an expert obviously
14:11:37 efried yeah, it's not really details of the system
14:11:55 efried In theory I agree it would seem as though that process could just rely on the root discovery doc, since it's just a superset of the versioned ones.
14:12:08 efried but I think perhaps the problem is that the service catalog is set up with the versioned endpoint
14:12:08 dansmith available microversion is totally details of the system
14:12:37 efried okay, point is we've already decided that's okay to expose, because it's in the root discovery doc (I think, /me confirms...)
14:13:18 efried yeah:
14:13:18 efried curl http://192.168.218.28/compute/
14:13:18 efried <snip> "version": "2.79" <snip>
14:13:56 efried "perhaps the problem is that the service catalog is set up with the versioned endpoint" shouldn't actually be a problem, which is the point.
14:14:45 efried mordred is working on a hacked up workaround for this in ksa and/or sdk to bridge the gap, but we (nova and the other services running afoul of this) really need to fix it in our APIs.
14:27:51 openstackgerrit Stephen Finucane proposed openstack/nova master: ec2: Move ec2utils functions to their callers https://review.opendev.org/662505
14:27:52 openstackgerrit Stephen Finucane proposed openstack/nova master: api: Remove 'Debug' middleware https://review.opendev.org/662506
14:38:31 efried kashyap: thank you for the thorough response on the ML ++
14:39:54 kashyap efried: No problem. I'll let Manuel file the bug
15:10:18 openstackgerrit Eric Fried proposed openstack/nova master: test cleanup: Remove skipIf test decorator https://review.opendev.org/685375
15:33:50 efried dansmith: are you aware of a reason we don't use oslotest.base.BaseTestCase in nova?
15:34:18 efried or stephenfin ^
15:34:29 stephenfin I'm not sure
15:34:36 stephenfin I'd guess just legacy
15:34:44 stephenfin nova is olllld
15:34:55 dansmith nova pre-dates oslo, so yeah something like that
15:36:45 efried cool, Ima go clean that up.
15:37:02 dansmith is there a reason?
15:37:49 efried tech debt reduction?
15:38:04 dansmith what's the tech debt here?
15:38:26 efried We have copies of half a dozen fixtures and are duplicating the setup steps for them.
15:38:38 efried Output capture, logging, timeout, tempdir...
15:38:55 dansmith we have copies of those in our fixtures?
15:38:58 efried yes
15:39:36 dansmith okay, the actual oslotest base doesn't seem to have much in it, but copies fo the fixtures make sense to squash
15:41:52 mriedem dansmith: this is a fix for a race in the numa live migration series (that came up in the ML), probably good to get in for an rc2 if we have one https://review.opendev.org/#/c/684409/
15:43:21 dansmith mriedem: hrm, do we call that method from anywhere else other than the periodic?
15:43:54 dansmith "accepted" could be considered to be non-terminal and thus "in progress"
15:44:19 dansmith oh, I see it's removing accepted
15:44:28 mriedem right, the ~ is confusing,
15:44:31 mriedem it's only used by the RT,
15:44:36 mriedem there is another method below that is used by the API
15:44:44 mriedem migration_get_in_progress_by_instance
15:44:58 mriedem that will still filter out 'accepted' state migrations
15:44:59 dansmith okay, so this is querying for finished migrations we need to clean up
15:45:20 mriedem which?
15:45:35 mriedem migration_get_in_progress_by_instance was written for the 2.23 change in the api to list in-progress live migrations that can be cancelled for force-completed
15:45:35 dansmith the one we're changing
15:46:00 dansmith yeah, I mean the host-n-node one here
15:46:00 mriedem the one we're changing is used by the RT to track incoming/outgoing migrations so we claim/don't drop resource claims on the source/dest host
15:46:06 dansmith right
15:47:42 dansmith so we need to backport that to stable/train to be ready for rc2?
15:48:52 mriedem yeah, i haven't checked yet if we have a stable/train set of patches up, but we probably do
15:49:00 dansmith the branch is there
15:49:28 mriedem yar https://review.opendev.org/#/q/project:openstack/nova+status:open+branch:stable/train
15:50:20 openstackgerrit Dan Smith proposed openstack/nova stable/train: Stop filtering out 'accepted' for in-progress migrations https://review.opendev.org/685387
15:50:31 dansmith mriedem: ^
15:52:04 dansmith biab
15:56:07 openstackgerrit Eric Fried proposed openstack/nova master: test cleanup: Use oslotest's Timeout fixture https://review.opendev.org/685389
15:56:19 efried dansmith: there's one for e.g. ^
15:58:20 dansmith ack
15:58:29 mriedem huh, interestingly enough, we don't set a migration.status during _post_live_migration before just marking the migration 'completed', meaning a user could attempt to abort/force-complete a live migration after the guest is transferred and we're in post-processing
15:58:41 mriedem it will probably fail, but we shouldn't even make that an option
15:58:51 artom dansmith, thanks for the train backport (sorry, laptop was rebooting/installing updates)
16:00:21 openstackgerrit Merged openstack/python-novaclient master: Stop silently ignoring invalid 'nova boot --hint' options https://review.opendev.org/684762
16:01:19 dansmith artom: np
