#openstack-nova - 2025-07-07
22:30:37 mikal Ugh, wrong url.

#openstack-nova - 2025-07-08
08:37:37 mhen Hi! #openstack-placement seems to be empty. Is this the right channel for Placement?
09:19:07 gibi mhen: yes it is the right one
09:20:37 mhen I've got a question regarding Placement:
09:20:45 mhen is my interpretation correct that Placement offers no means of adjusting its WSGI pipeline? It seems hardcoded here: https://github.com/openstack/placement/blob/ce677d96f2a5e18dcc5e10a2046cac9780a67cde/placement/deploy.py#L108-L117
09:20:47 opendevreview Kamil Sambor proposed openstack/nova master: Switch from Eventlet timeout https://review.opendev.org/c/openstack/nova/+/954324
09:21:00 mhen For other services, there is usually an api-paste.ini or something similar.
09:21:12 mhen So the audit middleware (https://docs.openstack.org/keystonemiddleware/latest/audit.html) cannot be used with Placement?
09:23:37 gibi mhen: good question let me double check
09:24:34 gibi mhen: it seems you are right we have a hard coded pipeline with no api-paste configuratbility
09:27:50 mhen alright, thanks for confirming

12:51:48 opendevreview Balazs Gibizer proposed openstack/nova master: [pci]Keep used dev in Placement regardless of dev_spec https://review.opendev.org/c/openstack/nova/+/954149
13:25:51 sean-k-mooney gibi: i reviewed the first couple of patches in your eventlet work and im back up to where i left off before (the stats priting one) for the most part they look fine to me
13:27:16 sean-k-mooney i also looked at kamils patch, https://review.opendev.org/c/openstack/nova/+/949754/17 i think ThreadingEventWithResult should just be a future not a event with a result, i woudl be interested to know if you agree but i left that as a comment in gerrit so no rush
13:56:05 zigo I tried using an older version of pymysql (the one in Bookworm), it didn't help. I tried doing a gc.disable() to check if that was another instance of the GC issue in Python 3.13, and it didn't help either. Anyone has an idea of what's going on?
13:56:05 zigo Hi there! I filled-up a new bug: https://bugs.launchpad.net/nova/+bug/2116186
13:59:07 gibi sean-k-mooney: on the ThreadingEventWithResult: I wanted a solution that changes as minimal in the current flow of the code as possible. Hence the direct replication of the Eventlet.Event behavior with threading.Event + a variable approach. The Future based approach has the drawback in my mind that the concurrent Future interface explicitly says that setting the result of the Future should happen by
13:59:13 gibi the implementation of an Executor. So it seems using a Future in that nova code would create a lot more code churn if it is even possible.
13:59:50 sean-k-mooney am so future are usabel with raw thread
13:59:58 sean-k-mooney so an executor is not stritly required
14:00:14 gibi https://docs.python.org/3/library/concurrent.futures.html#concurrent.futures.Future.set_result
14:00:33 gibi This method should only be used by Executor implementations and unit tests.
14:01:11 sean-k-mooney hum
14:01:22 sean-k-mooney that does not conform to what i would normally consider a future then
14:02:17 sean-k-mooney we would have to use a queue isnterad which is less obvious
14:03:43 gibi we started with a queue actually :) If you look back of previous PSs it is there
14:04:17 sean-k-mooney to me a future is concpetiulaly the same as a a queue of lenth 1 with blocking or non blocking gets dependign on if you pass a timeout to result
14:04:18 gibi then we learned that eventlet.Event has the behavior that it sends the same piece of result to all waiters so a queue with a lenght of 1 is not optimal
14:04:34 sean-k-mooney ah i see
14:04:40 gibi as it requires requeueing the same result :/
14:05:02 sean-k-mooney well that fan out or multi subsciber behaivor seams non standard too
14:05:07 gibi yep it is not
14:05:13 sean-k-mooney are we actuly reallying on that
14:05:27 sean-k-mooney i think for now im ok with the current approch then
14:05:34 gibi I'm not sure but I'm not willing to risk
14:05:40 sean-k-mooney but we may want to see if we can simplicy in the future
14:05:50 gibi yepp simplifying in the future is the way
14:06:05 gibi first have something that works and then optimize
14:10:37 sean-k-mooney so the asyncio future does nto have that limiation for what its worth
14:10:39 sean-k-mooney https://docs.python.org/3/library/asyncio-future.html#asyncio.Future.set_result
14:12:47 sean-k-mooney i ws not expectign thos to diverge in that regard
14:16:55 gibi yeah it is strange

14:23:59 sean-k-mooney looking at https://peps.python.org/pep-3148/ i think the landed on the current interface by emulating the java and in https://peps.python.org/pep-3156/#futures the intentioally diverged
14:25:13 sean-k-mooney anyway that enough of a distaction
15:02:09 Uggla Nova meeting in ~1h
15:31:16 gmaan Uggla: Due to Board meeting, I might not be able to join today meeting.

16:04:28 Uggla #info Please look at the gate failures and file a bug report with the gate-failure tag.
16:04:35 Uggla #info Please try to provide a meaningful comment when you recheck
16:04:50 Uggla #info https://bugs.launchpad.net/nova/+bug/2115980 opened by gibi. It seems nova next has regular failure due to this.
16:05:17 Uggla gibi, do you have more info about ^
16:05:53 clarkb the underlying issue is that zuul launcher can in some exceptional circumstances assign nodes to multiple providers within the same nodeset. This is due to zuul launcher wanting to be able to support k8s pods and openstack vms in the same nodeset
16:06:19 clarkb unfortauntely there were a few bugs (I think 2 or 3 at this point) that allowed it to mix providers more often than expected. The last of these known bugs was fixed around 2200UTC yseterday
16:06:35 gibi yepp the latest from me is that I'm not seeing the failure today any more
16:06:41 clarkb with each of the bugfixes the occurence of this issue should be lessened. And hopefully if we've fixed the bugs then the issue goes away
16:07:08 gibi I will keep the bug around for couple of days then I will close it if the problem does not re-occure
16:08:03 Uggla thanks clarkb, I appreciate your inputs.
16:08:33 Uggla thanks gibi
16:08:51 Uggla skipping next topic because gmann is not available.

16:09:25 Uggla #info Nova deadlines are set in the above schedule
16:09:50 Uggla Spec freeze was last week. So no new specs.

16:10:31 Uggla #link https://etherpad.opendev.org/p/nova-2025.2-status
16:12:02 Uggla We had a lot of interest just before the spec freeze around io threads.
16:12:58 Uggla Although, the specs were not approved this cycle. We may open a 2026.1 "directory" to keep the momentum around this activity.

16:14:51 Uggla elodilles, please go ahead.
16:14:59 elodilles i was on vacation last week, so i might missed some stuff
16:15:04 elodilles otherwise, i'm not aware of any issue with stable gates
