20:52:09 dansmith which is why I was saying they're two different concerns
20:52:12 mriedem that's kind of what i was thinking, it would be easier that way anyway
20:52:28 melwitt +1 to separate patches
20:52:30 mriedem we can build on the same functional test base i started
20:53:00 tssurya sure
20:53:02 dansmith yeah
20:53:31 mriedem tssurya: you want me to open a separate bug?
20:53:58 tssurya mriedem: yea
20:54:04 mriedem also, it's 11pm there right?
20:54:15 tssurya I will put up a patch tomorrow
20:54:17 mriedem do you get to bill belmiro for overtime?
20:54:30 tssurya mriedem: yes its 11pm :)
20:54:33 tssurya haha no
20:55:04 tssurya this is me learning stuff from the veterans :P
21:22:40 openstackgerrit Merged openstack/nova master: Remove mox in tests/unit/test_utils.py https://review.openstack.org/557883
21:52:10 mriedem cdent: edleafe: oh seers of http status code wisdom, hear my call, shall thou return a 400 or 409 for https://bugs.launchpad.net/nova/+bug/1763183 ?
21:52:10 openstack Launchpad bug 1763183 in OpenStack Compute (nova) "DELETE /os-services/{service_id} does not block for hosted instances" [High,Triaged] - Assigned to Matt Riedemann (mriedem)
21:52:41 mriedem i think 409
21:53:03 cdent i feel like I should have some kind of a 409phone
21:53:26 mriedem oh and if 409, guess what, @wsgi.expected_errors((400, 404))
21:53:30 mriedem we get to have a microversion debate
21:53:40 mriedem alex_xu: ^
21:54:16 mriedem although, it's an admin api...
21:54:40 edleafe mriedem: 400 usually means that you can make the call succeed by fixing the parameters, etc
21:54:44 cdent mriedem: yes 409
21:54:53 cdent because of what edleafe just said
21:55:06 cdent the server has to change to make things work, not the request
21:55:17 cdent but if the server does change, then things might work when you try later
21:55:47 mriedem yeah 409 is correct, but need to figure out if i can get by the existing expected errors decorator
21:55:57 mriedem but i think with the legal caveat in https://docs.openstack.org/nova/latest/contributor/microversions.html#when-a-microversion-is-not-needed 3rd bullet
21:55:58 mriedem we maybe can
22:08:47 mriedem oh my
22:08:53 mriedem this is the issue that keeps on giving
22:10:22 mriedem https://bugs.launchpad.net/nova/+bug/1679750
22:10:22 openstack Launchpad bug 1679750 in OpenStack Compute (nova) queens "Allocations are not cleaned up in placement for instance 'local delete' case" [Medium,Confirmed]
22:17:46 mriedem efried: seems delete_resource_provider should fail if delete_allocation_for_instance returns False...
22:18:03 efried ...
22:19:11 efried mriedem: 404 means there were no allocations for that consumer. Which is fine in the context of delete_resource_provider. Am I misunderstanding something?
22:19:18 mriedem getting a 409
22:19:20 mriedem and now i know why
22:19:37 efried 409 is gonna mean generation conflict.
22:19:44 mriedem no it's not that
22:19:45 efried And sorry, I missed that we return False for any 4xx
22:20:21 efried mriedem: I think 404 should return True (or somehow otherwise be ignorable) and any other 4xx should be a failure in delete_resource_provider - agreed.
22:20:22 mriedem so i'm not actually calling this https://github.com/openstack/nova/blob/fe976dcc559d059589a9ccf953a28e855abf50fb/nova/scheduler/client/report.py#L1920
22:20:49 mriedem because the list of instances is empty, because the compute service is down so when i delete the instance, the api removes it 'locally' but doesn't cleanup allocations
22:20:55 mriedem because of bug 1679750
22:20:55 openstack bug 1679750 in OpenStack Compute (nova) queens "Allocations are not cleaned up in placement for instance 'local delete' case" [Medium,Confirmed] https://launchpad.net/bugs/1679750
22:21:07 mriedem then https://github.com/openstack/nova/blob/fe976dcc559d059589a9ccf953a28e855abf50fb/nova/scheduler/client/report.py#L1922 fails with ResourceProviderInUse and we pass
22:21:41 efried noyce
22:22:11 efried mriedem: Me, I would rewrite a cascading RP deletion routine that doesn't rely on nova-isms.
22:22:30 efried You pass it a provider name/UUID and it goes after all related records, period.
22:22:42 efried I thought we had that somewhere already.
22:22:55 mriedem i just need to fix that bug
22:22:58 mriedem which has been around forever
22:23:30 mriedem i'm actually happy my test fails here, because the cascade silent fail means we're not doing something right
22:23:50 efried mriedem: Do you need help writing a real cascading delete in report client?
22:23:54 mriedem no
22:24:11 mriedem i need to fix that bug in the api local delete case to cleanup allocations in placement when the compute service is down
22:24:42 mriedem will be more clear when i post this code
22:24:44 efried Which you're going to need to do by getting placement to delete allocations based on the resource providers, not the instances.
22:24:53 mriedem no
22:24:56 mriedem we're deleting the instance
22:24:58 mriedem we know the consume
22:25:03 mriedem *consumer, so we get the allocations to delete
22:25:23 mriedem https://developer.openstack.org/api-ref/placement/#delete-allocations
22:25:46 cfriesen when doing a "git cherry-pick -x" do we generally preserve any conflicts or remove them from the commit message?
22:25:53 cfriesen for backporting
22:26:01 efried cfriesen: preserve (and explain if necessary)
22:26:11 mriedem cfriesen: i leave the conflicts in the commit message and make a note about what they are to help reviewers

#openstack-nova - 2018-04-12
00:04:01 mnaser hey
00:04:03 mnaser fun bug time
00:05:04 mnaser if a user builds an instance that if boot from volume (where nova creates the volume) and nova-compute fails to create the volume, the vm build fails, and it actually counts as a 'consecutive build failures'
00:05:29 mnaser so if i'm $bad_user and i try to launch 40 instances but keep hitting quota limits but keep trying again, i will effectively slowly but surely disable every compute node in the cloud
00:06:14 mnaser so while that feature is nice, i think we have to find a way to identify the type of failure it is
00:08:10 mnaser i mean we could disable that feature but that feels dirty
00:14:36 mriedem mnaser: yeah https://bugs.launchpad.net/nova/+bug/1742102
00:14:37 openstack Launchpad bug 1742102 in OpenStack Compute (nova) "Simple user can disable compute" [Undecided,Confirmed] - Assigned to jichenjc (jichenjc)
00:14:40 mriedem there is an ops ML thread about similar issues
00:14:59 mriedem i think we likely need to consider a whitelist of acceptable, not threshold inducing exceptions
00:15:30 mriedem the latest comments in there from jichen are actually the exact issue you're describing
00:17:07 mriedem but we can also be smarter and check quota before trying to create volumes
00:17:09 mriedem like we do for ports
00:17:27 mnaser mriedem: yeah, i think that's better, do we check quota at api layer for ports?
