#openstack-nova - 2018-01-19
17:11:03 edmondsw claudiub that does sound nice though
17:11:39 claudiub edmondsw: 3.929s per 121 tests
17:13:22 claudiub ok, so, 3.8 sec with no change. 3.929 with mock.Mock(autospec) (oslotest), and 7.5 sec with mock.create_autospec
17:15:03 mdbooth lyarwood: The workaround is to use getattr instead, because that has consistent behaviour
17:15:11 mdbooth i.e. it raises an exception
17:16:39 mdbooth lyarwood: Assuming you've got local changes, I'll leave ^^^ in a review comment
17:16:52 lyarwood mdbooth: yeah thanks
17:18:34 mdbooth https://bugs.launchpad.net/oslo.versionedobjects/+bug/1552927
17:18:35 openstack Launchpad bug 1552927 in oslo.versionedobjects "hasattr() function behavior differences between Py27 and Py34" [Undecided,New]
17:18:43 mdbooth lyarwood: Already been reported ^^^^
17:19:34 mdbooth obj.attr_is_set()...
17:21:16 lyarwood mdbooth: ah!
17:21:42 mdbooth Just testing that
17:22:34 mdbooth lyarwood: Works, at least for that test
17:22:48 lyarwood mdbooth: yeah works for me
17:23:48 openstackgerrit Lee Yarwood proposed openstack/nova master: libvirt: QEMU native LUKS decryption for encrypted volumes https://review.openstack.org/523958
17:35:28 claudiub mdbooth: gonna send you a link soon. already 60 seconds passed while trying to execute unittests which shouldn't last more than 10 seconds. :)
17:42:40 claudiub mdbooth: https://github.com/bclau/nova/tree/autospec-issue
17:43:22 mdbooth lyarwood: I'd have left you a +1 if Jenkins had voted already. I'd appreciate if you consider the readability of the new test, though.
17:43:53 mdbooth My eyeballs aren't good at computing diffs.
17:43:54 claudiub execution time: vanilla: ~10 seconds. oslotest mock.MagicMock(autospec): ~14.5 sec. mock.create_autospec: I dunno, a few hundred seconds, still running.
17:44:54 mdbooth claudiub: That's great info, and definitely something I hadn't appreciated.
17:45:11 mdbooth I think I've used create_autospec in a few places in the past.
17:45:53 claudiub it's definetely great, but the fact that it autospecs literally everything can be problematic.
17:46:19 claudiub and I have sent pull requests to python 3 and the mock library, but no response for at least half a year
17:46:35 claudiub and there hasn't been any updates to the mock library since more than 12-13 months
17:47:03 claudiub Ran 364 tests in 434.626s
17:53:05 openstackgerrit David Rabel proposed openstack/nova stable/pike: Fix format in live-migration-usage.rst https://review.openstack.org/535871

18:38:02 openstackgerrit Jim Rollenhagen proposed openstack/nova master: Ironic: negotiate microversion to allow downgrade to Pike https://review.openstack.org/535786
19:13:34 cfriesen found an interesting glance/nova interworking issue. if doing a snapshot, and cinder/glance are both on ceph, nova tries to shortcut the snapshot then set the location in glance. But by default glance won't let you set the location of an image, so this fails.
19:16:09 cfriesen correction, not cinder, but when instance backend is ceph.
19:57:39 cburgess cfriesen Sounds like nova is doing the right thing but glance just isn't configured properly. Sounds like maybe a release note or something is needed?
19:57:54 cburgess cfriesen I suspect cinder will run into the same issue.
20:22:17 fried_rolls you gotta be effin kidding me. The bottom three patches, all +W'd, got zuul -1 with (three *different*) spurious failures. The fourth patch - the first one with a -1 - passed.
20:24:05 openstackgerrit OpenStack Proposal Bot proposed openstack/nova master: Updated from global requirements https://review.openstack.org/535919
20:25:32 ildikov fried_rice: mine got a time_out error on the gate, sooo close, but no...
20:26:46 fried_rice Boo. I feel your pain.
20:43:30 fried_rice figleaf regarding https://review.openstack.org/#/c/526540/17/nova/scheduler/client/report.py@390 -- the only possible reason I can see for it having been split out before was LOG.warning vs .error.
20:43:59 fried_rice figleaf But given that the error text is (at least) as descriptive as what was there before, are you cool with it?
20:55:35 openstackgerrit Ihar Hrachyshka proposed openstack/nova master: DNM testing whether lib/neutron switch breaks this repo https://review.openstack.org/535947
21:02:27 cfriesen cburgess: I've been diving down into the rathole of the nova/glance interaction. turns out glance's policy stuff is all mucked up, so that enabling nova's snapshot in this case requires glance to be configured insecurely. It might be possible to use service tokens to fix it, but nova doesn't send them by default.
21:02:39 cfriesen speaking of which...anyone know why send_service_user_token is False by default?
21:03:19 cfriesen cburgess: the glance folks suggested a workaround of a separate glance node that is configured less secure, which is only accessible by other openstack components. kind of icky if you ask me.
21:08:02 figleaf fried_rice: It just seemed like a bigger behavior change than it set out to be
21:08:13 figleaf fried_rice: it's not a showstopper by any stretch
21:08:20 fried_rice coolcool.
21:09:58 leakypipes fried_rice: k, your patches are now reviewed up to the WIPs.
21:10:11 fried_rice leakypipes Thanks dude. Starting to work through 'em.
21:10:17 leakypipes yup, np
21:11:52 openstackgerrit Matthew Edmonds proposed openstack/nova master: Fix bad autospec usage https://review.openstack.org/535806
21:15:21 edmondsw claudiub ^ fixed a pep8 error. Interested in how you feel about that patch
21:16:20 edmondsw I'm not against using the fixture you got in oslotests if the performance is better, but this might be quicker to merge and doesn't preclude your changes coming later
21:16:44 edmondsw doesn't have a significant performance impact at this small scale that I've detected
21:20:26 edmondsw cfriesen send_service_user_token is False by default simply because you have to configure credentials for that to work
21:21:06 edmondsw I'd like for send_service_user_token to go away, and just have the code detect whether it has credentials or not and use that as the determining factor, but that's a nit
21:22:37 openstackgerrit Hongbin Lu proposed openstack/nova master: Handle RPC timeout on get_console_output https://review.openstack.org/525335
21:28:03 cburgess cfriesen Thats very icky, especially considering that its worked this way for a while (the nova side I mean).
21:28:20 cburgess nova merged this stuff shortly after Tokyo
21:37:56 cfriesen cburgess: I think it might be related to the glance v1/v2 stuff
21:38:06 cburgess cfriesen Hmm yeah I think you might be right.
21:59:39 openstackgerrit Jim Rollenhagen proposed openstack/nova master: Ironic: negotiate microversion to allow downgrade to Pike https://review.openstack.org/535786

23:50:14 Spazmotic Hrm.
23:50:40 fried_rice Do tell
23:50:49 Spazmotic Just reading over what leaky said
23:51:07 fried_rice Yeah, I still think there's a hole there.
23:51:16 fried_rice I meant to put it on the PTG agenda, but I think I forgot.
23:51:20 fried_rice ...
23:51:59 Spazmotic https://github.com/openstack/nova/blob/master/nova/api/openstack/placement/handlers/allocation.py#L335-L343
23:52:24 Spazmotic This is what I see.. It's if the set allocations POST call doesn't receive any data, it pulls all the consumers allocations that exist and runs allocation.used = 0
23:52:28 fried_rice Spazmotic You going to be at the PTG?
23:52:44 Spazmotic Nah i'll be in Korea and honestly i think i'm too new to the scene to cause a fuss :D
23:53:08 Spazmotic I will re-read the code tonight, maybe I just don't understand it properly
23:55:33 fried_rice Spazmotic Oh, and the other thing was a way to add/update/delete individual pieces of allocation rather than the whole payload.
