#openstack-nova - 2018-08-02
21:03:15 lbragstad yeah - i would agree
21:03:30 lbragstad and i'm curious to flush those out as we go
21:04:19 lbragstad i assume that's going to have an impact on implementing unified limit support for instances, yeah?
21:05:03 sean-k-mooney lbragstad: ya there are some edge case to knowing if you are at or below quota if connect to a cell goes down
21:05:38 lbragstad huh - interesting
21:05:53 sean-k-mooney it would be similar to the problem you would have with keysone federattion if you lost the connection to a remote cloud and contiued to consume resoces on the local cloud and then it came back
21:06:10 lbragstad oh - sure
21:06:32 sean-k-mooney while the connect is broken you could exceed the gloabl limt. then the question is how to hanelit when you get the full view again
21:06:42 lbragstad right...
21:07:30 sean-k-mooney most other project dont shard there resocue view teh same way nova can with cells so ya im sure nova will find edgecases
21:07:34 lbragstad i guess the way we've been thinking about that (originally something sdague thought of)
21:07:59 lbragstad was to just keep things as they are, reject new claims, and give the user an opportunity to clean things up or escalate to an administrator
21:08:59 sean-k-mooney ya that seams like the sane think to do atleast at first until operator start telling us to do something else
21:15:55 mriedem cfriesen: heh https://github.com/starlingx-staging/stx-nova/commit/71acfeae0d1c59fdc77704527d763bd85a276f9a#diff-1aca090de4ab90afbc1c8d84b13a56f7R478 - i think that is one condition too late :)
21:16:03 mriedem by the time that runs, i think we've already dos'ed neutron
21:26:26 sean-k-mooney melwitt: quick question regardign os-vif stable releases. do you make them when you make sable release of nova?
21:27:23 melwitt sean-k-mooney: usually yes. around and after the third milestone is different because of the release freezes
21:28:04 melwitt IIUC, we are frozen from doing stable/rocky releases until stein opens
21:28:26 sean-k-mooney melwitt: ok there are a few test/tox fixes that would be nice to backport but nothing functional
21:29:32 melwitt sean-k-mooney: I see. I actually requested a FFE for the noop plugin loading bug that got approved, so I released 1.11.1 from the stable/rocky branch recently
21:29:40 sean-k-mooney like https://review.openstack.org/#/c/567942/ to run all of the py27 unit test instead of only a subset.
21:29:57 sean-k-mooney oh cool
21:30:42 melwitt I see. we can release stable/queens at any time, but I'm not sure how releasing the tox fix will help anyone? just needs to make it into the stable/queens branch right? for developers to benefit
21:31:01 melwitt oh, because it runs in a CI job
21:31:10 sean-k-mooney ya
21:31:23 sean-k-mooney its to make sure we dont backport stuff that breakes py27
21:31:36 sean-k-mooney that said all the unit tests are running under by 35
21:31:47 sean-k-mooney *py35
21:32:37 melwitt okay, since that's queens I think that's okay. if you want to do a release for an older stable branch, you can just propose it and let me know so I can ack it
21:33:01 melwitt smcginnis: can you sanity check me on that? ^
21:33:41 melwitt is it okay to release stable/queens for non-client libraries during freeze? is freeze only for rocky or for all branches?
21:34:12 sean-k-mooney well in this case its more to highlight the fact that there are some pendign stable/X backports and that im not sure if the nova stable team reguraly checks os-vif
21:34:29 melwitt pending as in, not merged?
21:34:39 sean-k-mooney yes
21:35:31 melwitt okay. just have to let people (stable cores) know to take a look if there's something important there
21:35:36 sean-k-mooney such as this one for pike from december that i proosed back in january and got a +2 from mriedem_afk 4 months ago https://review.openstack.org/#/c/531465/
21:37:03 smcginnis melwitt: Yep, that looks right. Freeze just applies to rocky work.
21:37:15 melwitt smcginnis++
21:37:31 sean-k-mooney i have core rights on master not the sable/branches so while i do flag pending backports to the nova sable team every now and then there is not much more i can do if they dont get reviewed
21:38:19 sean-k-mooney anyway there is nothing breakign the gate or that customer are screaming about that im aware of so just an FYI
21:39:53 melwitt sean-k-mooney: okay, thanks for letting me know. I'll see if I can find someone for the second +2s
21:46:01 openstackgerrit Merged openstack/os-vif stable/pike: Check if interface belongs to a Linux Bridge before removing https://review.openstack.org/531465
21:46:26 melwitt tonyb: fancy reviewing a os-vif backport to fix their tox py27 job? https://review.openstack.org/567942
21:47:29 tonyb melwitt: done
21:47:38 melwitt thank you sir
21:47:51 tonyb melwitt: no problem at all
21:54:55 sean-k-mooney tonyb: thanks.
21:55:50 tonyb sean-k-mooney: np. It's my very minor super power ;P
21:56:30 sean-k-mooney by the way looking at http://ci-watch.tintri.com/project?project=nova&time=7+days i do not see teh intel nfv ci. https://wiki.openstack.org/wiki/ThirdPartySystems/Intel_NFV_CI has not been updated since febuary. anyone rememebr the last time they saw it comment on something?
21:56:35 openstackgerrit Merged openstack/os-vif stable/queens: fix tox py27 job https://review.openstack.org/567942
21:57:26 melwitt sean-k-mooney: can't remember. it's been awhile
21:58:35 sean-k-mooney i have been waiting for it to comment on some change i was doing to networking-ovs-dpdk... i guess ill jsut do the testing myself.
21:59:07 tonyb sean-k-mooney: If you really cared to find out you could add the notes ref to you nova repo and then grep the notes for a comment from that CI
21:59:15 tonyb it *might* work
22:00:03 sean-k-mooney tonyb: oh? im not sure i follow
22:00:45 tonyb sean-k-mooney: gimme 5 to find a link
22:00:51 sean-k-mooney as in a gerrit query for a reviewer?
22:01:18 tonyb sean-k-mooney: Oh you could do that as well
22:01:47 melwitt oh yeah, good idea
22:02:11 tonyb sean-k-mooney: So looking at https://git.openstack.org/cgit/openstack/nova/commit/?id=2499f616094f63ed0a1a3c201789d14cc61a62c4
22:02:43 tonyb 'notes' get added to each review based on code-reviews. they're in a seperate ref
22:03:09 tonyb so you can just add that ref to your nova repo and then when you do git show on a SHA you'll get to see the reviewers
22:03:25 tonyb so the CI votes (but not comments) would be included.
22:04:34 tonyb https://review.openstack.org/#/q/reviewedby%3Aintel-nfv-ci
22:04:46 tonyb look slike it's still voting
22:05:58 sean-k-mooney maybe what does exception meen next to a ci comment https://review.openstack.org/#/c/584829/
22:06:44 tonyb sean-k-mooney: Oh it means it's voting but not doign anythign helpful ;P
22:07:35 sean-k-mooney ah it makes perfect sense lol
22:07:56 tonyb ;p
22:08:17 tonyb sean-k-mooney: Let me see if I can find the last time it voted +1
22:10:26 tonyb sean-k-mooney: Nope my gerrit fu is weak right now. I'll grab some coffee and try again
22:11:12 sean-k-mooney well looking at the log server it has not uploaded anything sice the 18th http://52.27.155.124/portland/2018-07-18
22:13:48 sean-k-mooney tonyb: thanks for trying in anycase. i might reach out and ask what the status is.
22:20:34 openstackgerrit Takashi NATSUME proposed openstack/nova master: Reno for notification-transformation-rocky https://review.openstack.org/588403
22:35:28 melwitt lbragstad: sorry for the delayed reply, but yeah what I was thinking was to look at migrating to keystone limits in stein, not yet going for the enforce part. johnthetubaguy had also mentioned that a two-stage approach to the migration might make migration easier from an operator perspective but I didn't understand that bit
22:38:43 melwitt side is the enforce with what we already have. then next stage will be to move to oslo.limit for enforcement
22:38:43 melwitt we have other work we'd like to do like be able to set quota limits for custom resource classes and where we're at right now, we could do that via our existing quota classes API, but then that will leave more to have to migrate to keystone limits when we move. so I was thinking maybe we should move to keystone limits first, then let the limits piece of custom resource class quotas be covered by unified limits, and all we do on our
22:43:20 lbragstad interesting melwitt
22:43:46 lbragstad so - you'd query keystone directly for limit information as opposed to using oslo.limit?
22:44:24 melwitt yeah. I actually didn't know the limit query was supposed to go through oslo.limit. if it does, we could do that, I just missed it or forgot
22:44:56 melwitt or are you saying limit + enforce are coupled?
22:45:01 melwitt in oslo.limit
22:45:04 lbragstad technically - it probably doesn't _have_ to go through oslo.limit, but that's where we were going to hide all the logic that understands the project tree
22:45:12 melwitt right okay
22:45:18 tonyb sean-k-mooney: Ahh when it votes it doens't actually 'vote' it just leaves a comment so it's back to groveling in the review metadata :(
22:45:44 lbragstad melwitt: i'm trying to map terms, but i was under the assumption that enforcement would be a requirement?
22:45:49 openstackgerrit Eric Fried proposed openstack/nova master: [placement] Add /reshaper handler for POST https://review.openstack.org/576927
22:45:50 openstackgerrit Eric Fried proposed openstack/nova master: reshaper: Look up provider if not in inventories https://review.openstack.org/585033
22:45:51 openstackgerrit Eric Fried proposed openstack/nova master: Make get_allocations_for_resource_provider sane https://review.openstack.org/584598

22:45:56 openstackgerrit Eric Fried proposed openstack/nova master: Compute: Handle reshaped provider trees https://review.openstack.org/576236
22:45:57 openstackgerrit Eric Fried proposed openstack/nova master: WIP: Remove redundant _update()s https://review.openstack.org/588091
22:46:15 lbragstad if not - then it sounds like something we can build into oslo.limit or consider supporting (since it's the thing raise exceptions to the service)
22:46:26 melwitt lbragstad: it is, sorry. I mean whether it's one call or two calls in oslo.limit to do limits vs enforce
22:46:49 lbragstad oh - the thing that protects against race conditions?
22:47:21 melwitt sorry, I think I'm confusing things and I haven't looked at the POC code in awhile
22:47:46 lbragstad the skeleton of oslo.limit has that implemented in the context manager https://github.com/openstack/oslo.limit/blob/master/oslo_limit/limit.py#L60-L62
