09:21:09 bauzas oops, I did that in a wrong chan (-ptg) but
09:21:13 bauzas good morning Nova :)
09:21:26 bauzas lyarwood: looking
09:22:04 lyarwood bauzas: morning and thanks!

09:53:08 johnthetubaguy alex_xu: I think that restriction on Name is really recent, I am remembering that wrongly?
09:56:34 alex_xu johnthetubaguy: yes, we just didn't that in Ocata by the patch of server query parameter validation
09:56:54 alex_xu s/didn't/did/
09:58:07 johnthetubaguy alex_xu: so we do have better behaviour now, that when the bug was reported at least, but it seems really easy to "fix" the old behaviour, as proposed
09:58:18 johnthetubaguy s/that when/than when/
09:59:04 openstackgerrit Alin Balutoiu proposed openstack/os-vif master: vif_plug_ovs: Skip setting MTU on Windows when plugging devices https://review.openstack.org/441855
09:59:28 alex_xu johnthetubaguy: is that old behaviour? as my understand, the API always return 500 with invalid regex, so it should be never works in the before
10:00:03 alex_xu let me check the bug report, whether I missed something
10:00:35 johnthetubaguy alex_xu: what I mean is, the current behaviour is better than the old 500
10:00:46 johnthetubaguy alex_xu: its just odd from a user perspective
10:00:52 alex_xu johnthetubaguy: ah, yea
10:01:34 johnthetubaguy alex_xu: they have a list of servers, they are using filtering by name to show some server details, but some of the queries return 400 (or 500) instead of the server
10:02:29 johnthetubaguy defaulting to exact match when it was an invalid regex seemed quite nice, although I guess its hard to debug your regex that way
10:03:15 alex_xu johnthetubaguy: yea, and that sounds like API behaviour change, doesn't sounds like we can change API without microversion
10:04:52 johnthetubaguy if it were 500 -> results like when this was first proposed, it wouldn't be, which is the odd thing I guess
10:05:50 johnthetubaguy if it were name_regex= I wouldn't worry about this either I guess
10:06:29 bauzas lyarwood: AFAIR, nova unittests can run behind a mysql driver backend instead of sqlite
10:06:50 bauzas given the Database fixture does use the default oslo.db values for creating the DB
10:07:07 mdbooth_ bauzas: I did some work on this a couple of years ago and there were a few wrinkles but mostly it just worked
10:07:15 mdbooth_ For unit tests, that is
10:07:16 bauzas for functional tests, we need to make sure it does use the same path
10:07:38 lyarwood bauzas: yeah I think you need to actually configure mysql/mariadb to use the default creds for it to work right?
10:07:56 bauzas yeah
10:07:57 mdbooth_ IIRC, the biggest wrinkle at the time was that sqlite (used by default) allowed millisecond accuracy in timestamps, whereas mysql only does 1 second
10:08:15 mdbooth_ This broke a bunch of unit tests which wrote non-rounded seconds into the db and expected to read the same value back.
10:08:42 bauzas here, I suppose lyarwood wanna test some very specific ones
10:08:51 bauzas not running the whole job
10:09:09 lyarwood bauzas: well downstream we hit a func test failure caused by the sqlite version we are shipping in RHEL
10:09:15 alex_xu johnthetubaguy: yes, agree that is odd
10:09:24 mdbooth Although running the whole job isn't a bad idea. There are a bunch of very interesting semantic differences.
10:09:26 lyarwood bauzas: as we don't support sqlite we need to switch these jobs over to mariadb
10:09:28 alex_xu johnthetubaguy: just check the history, we fix the 500 at https://review.openstack.org/#/c/344945/
10:09:49 bauzas lyarwood: yeah I heard that from migi
10:09:58 johnthetubaguy alex_xu: yeah, I remember worrying about that bug fix we had pending when approving that one
10:10:34 bauzas lyarwood: so you would run a specific functional tests job backed by mariadb, right?
10:10:40 bauzas not all the UTs ?
10:11:54 lyarwood bauzas: well, all of the func tests that we can using mariadb
10:12:04 lyarwood bauzas: and any UTs that are using the DB as well tbh
10:12:31 bauzas okay, so fixing upstream the wrinkles that mdbooth said would then a good idea
10:12:53 bauzas at least, the first step is to configure the jobs and see what are the results
10:13:08 bauzas I'd only consider functional tests at a first step tho
10:13:15 alex_xu johnthetubaguy: so probably we can introduce "/servers?name=in:VM1,VM2" in the future
10:13:24 alex_xu for the exact match
10:13:36 bauzas alex_xu: I had a patch up for the in: tag a while ago
10:13:49 alex_xu bauzas: yea, I learned from that
10:14:07 johnthetubaguy alex_xu: oh... the in operator, thats a good way around that one
10:14:16 bauzas alex_xu: disclaimar, I haven't read the above discussion, so no context here yet
10:14:25 bauzas disclaimer* even
10:14:59 johnthetubaguy alex_xu: so I -2ed that patch, I can catch up with sneti on why I did that later on
10:15:38 alex_xu johnthetubaguy: ok, if sneti happy with that, we better to have a patch to tell the user how to match exact name in the current API behaviour
10:15:57 alex_xu in api-ref
10:16:22 johnthetubaguy alex_xu: yeah, I can't remember what we say in there right now
10:16:53 johnthetubaguy "Filters the response by a server name, as a string. You can use regular expressions in the query. For example, the ?name=bob regular expression returns both bob and bobb. If you must match on only bob, you can use a regular expression that matches the syntax of the underlying database server that is implemented for Compute, such as MySQL or PostgreSQL."
10:16:57 johnthetubaguy thats probably OK
10:17:55 alex_xu oops, that depend on the underlying database, that is bad :(
10:20:10 alex_xu and we validate the regex with python first...https://github.com/openstack/nova/blob/master/nova/api/validation/validators.py#L40

10:36:48 openstackgerrit Sivasathurappan Radhakrishnan proposed openstack/nova master: Port binding based on events during live migration https://review.openstack.org/434870
10:49:53 johnthetubaguy alex_xu: been meaning to reach out to you about things a bit related to what is written down here: https://review.openstack.org/#/c/440917/9/doc/contributor-guide/source/non-native-english-speakers.rst
10:50:26 johnthetubaguy alex_xu: looking at creating some place where folks can share good ideas on how to work with upstream when you are a non-native-english-speaker
10:50:41 johnthetubaguy alex_xu: would love your help with that, if you are keen?
10:58:59 openstack Launchpad bug 1670319 in OpenStack Compute (nova) "Reschedule of failed instance doesn't happening when scheduler placed two instances to the same ironic node" [Undecided,New]
10:58:59 vsaienk01 jroll, dtantsur, mriedem fyi found issue when reschedule won't happening for failed instance https://bugs.launchpad.net/nova/+bug/1670319 it leads to sporadic ironic-multinode job failures
11:03:03 bhagyashri_s johnthetubaguy: Hi, I have put my thoughts on patch: https://review.openstack.org/#/c/409644/ could you please take some insight and suggest your opinion about it?
11:04:21 johnthetubaguy bhagyashri_s: I don't think we should do the delete in the API, we try to keep the API doing as little work as possible, and dispatch any long running work to either a conductor worker or a compute worker
11:05:52 bhagyashri_s johnthetubaguy: ok.
11:08:47 bhagyashri_s johnthetubaguy: thank you.
11:10:26 johnthetubaguy bhagyashri_s: no problem, it was an idea certainly worth thinking about, but yeah it would chance how we scale the ystem
11:11:41 openstackgerrit Roman Podoliaka proposed openstack/nova master: nova-status: require placement >= 1.4 https://review.openstack.org/441881
11:11:50 bhagyashri_s johnthetubaguy: yeah.
11:17:08 gibi johnthetubaguy: hi! as we agreed on the PTG there is a spec proposed to show the scheduler-hints in the response of the GET /servers/ https://review.openstack.org/#/c/440580/ . If you have time could you check it please?
11:18:04 johnthetubaguy gibi: yeah, I hope to get to that
12:24:31 alex_xu johnthetubaguy: haha, that is sweet doc, happy to help that
12:25:45 johnthetubaguy alex_xu: awesome, thanks. The SWG is trying to help share best practices around all parts of the community, and look for new ideas to improve things too
