15:06:09 gmann gibi: no, it is with other server extended attributes
15:06:38 gibi but we don't want to show all the exteneded attribute as there are sensitive informations there like the hypervisor_hostname
15:06:51 gmann humm
15:06:52 gibi but the hostname of the VM is harmless
15:07:02 gibi that does not reveal any infra informatiuon
15:07:11 gmann yeah
15:09:55 gmann gibi: I think in this exceptional case when there is related API change, I am getting your point.
15:10:18 gmann let me rethink if any other way it can create inconsistency other seems ok to me
15:10:23 gmann otherwise
15:11:07 gibi gmann: for me it is the case when our strict rules (microversion and policy deprecation) get in our way to provide a meaningful and (for me) safe change for the end user
15:12:05 gmann yeah.
15:13:09 gibi and I support our strict rules in general as it is a safety net to avoid breaking users, but in this specific case I think we can allow an exception for the rules
15:14:12 gmann i agree. especially with the point of using 2.90 changes completely (request and see the hostname by end users)
15:15:22 gmann I think I am convinced now :). thanks
15:17:15 opendevreview Merged openstack/placement master: Bump os-traits to latest 2.6.0 https://review.opendev.org/c/openstack/placement/+/805830
15:24:27 gibi gmann: thank you for the discussion
15:29:33 melwitt lyarwood: thanks for noting that I need to rebase the consumer types set, going to do that now and will need +W reapplied after
15:29:59 lyarwood melwitt: I think we can get away without a rebase now
15:30:09 lyarwood melwitt: zuul should do it for us once it's rechecked
15:30:33 melwitt o rly
15:30:35 melwitt ok
15:30:39 melwitt I'm glad I said something. thanks I can do that
15:30:47 stephenfin gmann: gibi: Sorry, I had meetings. It _sounds_ like you've come to a conclusion and are ultimately happy with what I've done?
15:31:22 gmann stephenfin: yeah, it looks good to me, reviewing that patch...
15:33:14 gibi ohh consumer_types are going in \o/
15:36:30 melwitt yes \o/
15:36:54 lyarwood assuming it's rebased by zuul ;)
15:39:26 lyarwood cool looks like it did
15:39:58 lyarwood brb
16:07:09 gmann stephenfin: left few comments on test and documentation
16:36:31 artom def _do_old_style_instance_list_for_poor_cellsv1_users()
16:36:39 artom Right, who's the joker responsible for that?
16:37:25 artom Mr Smith.
16:37:29 sean-k-mooney someone who took pitty on the cell v1 users
16:37:39 sean-k-mooney then need all the care we can give them
16:37:41 artom (Yes, this is very old code - looking at a Queens bug report)
16:39:33 sean-k-mooney *********
16:39:58 sean-k-mooney they are mising url quoting
16:40:00 sean-k-mooney https://github.com/sqlalchemy/sqlalchemy/blob/master/lib/sqlalchemy/engine/url.py#L542
16:43:23 artom ?
16:44:27 sean-k-mooney the query args secotion fo the url is enccoded using quote_plus
16:44:40 sean-k-mooney where spaces are replaced with +
16:44:58 sean-k-mooney but the protocol seciont of the url has a + in it that is not a spec
16:45:02 sean-k-mooney *space
16:45:27 sean-k-mooney so if i decode it with unqoute technically the queary args wont be decoded properly
16:45:51 artom Ohhh
16:46:33 sean-k-mooney which means if i want to properly decode it i need to hande eveything beofre the ? one way and everything after the other way
16:46:47 sean-k-mooney i htink im just going to skip that and replcae % with %%
16:47:06 sean-k-mooney and hope that config parser is ok with the url encoded value
16:47:35 artom Yeah
16:47:51 artom We'll get the tripleo job to run with the fix as a dependency
16:48:06 sean-k-mooney ya i can add a depends on
16:48:09 sean-k-mooney that works with ooo right
16:48:18 sean-k-mooney via a dnm patch
16:50:46 artom It should
16:51:23 artom I was thinking the other way around, have an ooo DNM patch depending on the nova one, but whatever works
16:53:11 sean-k-mooney artom: that is what im going to do
17:01:33 lbragstad gmann so - i'm working through a test where a system-admin creates a server in a project (specifically trying to find what needs to change in KSA to make that possible)
17:02:21 lbragstad and it looks like the first failure is https://github.com/openstack/neutron/blob/master/neutron/notifiers/nova.py#L265 because neutron is using a novaclient with a project-scoped token (instead of a system-scoped one)
17:03:35 sean-k-mooney that nova client should be using the token set in the neutron.conf
17:03:53 sean-k-mooney which woudl normally be the nova user or a service user
17:03:59 lbragstad yeah - exaclty
17:04:00 lbragstad and it does
17:04:02 lbragstad so - that's good
17:04:28 sean-k-mooney so the nova user would have to be a project member or if it was a system_memeber we need a new parmater to specifcy a project id i ugess
17:04:31 sean-k-mooney *guess
17:04:55 sean-k-mooney the api its calling however is admin only and not really proejct specfic
17:05:15 sean-k-mooney im surpised that is failing
17:05:25 lbragstad in https://github.com/openstack/neutron/blob/master/neutron/notifiers/nova.py#L265 specifically - the nova user would need to be a system-admin https://github.com/openstack/nova/blob/master/nova/policies/server_external_events.py#L27
17:05:40 lbragstad iiuc
17:05:41 sean-k-mooney yes
17:06:48 sean-k-mooney so the nova user woul dhave to be a system_admin
17:06:52 lbragstad right
17:07:10 lbragstad so that neutron can use that user with a client to create external events in nova
17:07:38 sean-k-mooney yes
17:07:46 sean-k-mooney its calling this endpoint https://docs.openstack.org/api-ref/compute/?expanded=run-events-detail#run-events
17:08:06 lbragstad in addition to that - we'd need a way to make sure neutron is using the right scope when building the auth request
17:08:24 lbragstad https://github.com/openstack/neutron/blob/master/neutron/notifiers/nova.py#L61
17:09:35 sean-k-mooney yep we woudl need to add a new config parmater ofor the scop to use
17:09:41 sean-k-mooney https://github.com/openstack/nova/blob/master/nova/policies/server_external_events.py#L24-L35
17:09:54 sean-k-mooney in this case system scope
17:10:05 lbragstad and i imagine that's going to be a pattern we need else where?
17:10:43 lbragstad i'm expecting this is just the first time i'm hitting this issue, but there are other layers to the onion
17:11:00 sean-k-mooney well its going to happen but worse for volume resize
17:11:17 sean-k-mooney cinder currently has bug where it calls that endpoing with the users token
17:11:17 lbragstad sure - that makes sense
17:11:24 sean-k-mooney instead of actully using an admin one
17:12:01 sean-k-mooney but yes i expect the pattern to be the same or similar
17:12:23 dansmith sean-k-mooney: is that a bug, or just how it used to work?
17:12:26 sean-k-mooney im surprised that it got that far by the way
17:12:31 sean-k-mooney dansmith: no that is a bug
17:12:45 sean-k-mooney which ooo worked around by hardcodeing cidner to call nova admin api endpoint directly
17:12:57 dansmith is this the swap volume api or something else?
17:13:08 lbragstad fwiw - this is what i'm doing to recreate this https://review.opendev.org/c/openstack/tempest/+/805452
17:13:17 sean-k-mooney i tought it was resize for nfs but ill have to go look it up
17:13:38 sean-k-mooney lbragstad: by the way i was expecting a failure before that when nova called neutron to bind the port
17:13:46 lbragstad yeah - me too
17:13:52 sean-k-mooney we do that as a admin
17:13:58 dansmith okay just saying.. the swap volume api has always been user-visible, but problematic.. people have used it for non-cinder tasks before and we discussed whether or not they should be able to.. but they are (or were)
17:14:36 sean-k-mooney dansmith: im pretty sure the issue i was refering too was for online volume resize whne cinder calls nova back to tell it its done
