| 19:09:48 | sdague | tidwellr: it actually came up recently, our uuid validation is much looser than people realized, this is probably another instance of that | |
| 19:13:50 | melwitt | be careful with forcing everything to lowercase in clients though, we had a bug a long time ago in novaclient where it tried to lowerc flavor names but they could have been created with mixed case and could cause them not to be found in request cache https://bugs.launchpad.net/python-novaclient/+bug/1446850 | |
| 19:13:50 | openstack | Launchpad bug 1446850 in python-novaclient "flavor-show of mixed case flavorid fails" [High,Fix released] - Assigned to melanie witt (melwitt) | |
| 19:14:10 | mriedem | melwitt: what about mogan indeed http://git.openstack.org/cgit/openstack/mogan/tree/mogan/network/api.py#n120 | |
| 19:14:13 | mriedem | any of that look familiar? | |
| 19:14:39 | tidwellr | sdague: thanks, I'll get a bug filed by EOD | |
| 19:15:33 | sdague | tidwellr: cool | |
| 19:15:57 | melwitt | mriedem: yes ... surprised they wanted to use that, heh | |
| 19:17:50 | mriedem | finding out how to write a unit test for this hide_server_addresses thing is going to be the hard part | |
| 19:19:44 | sdague | mriedem: yeh, you can't use the real test condition, because sqlite goes case sensitive | |
| 19:22:36 | sdague | I don't remember if we ever landed the patch to run real tests with mysql backend for the other case sensitive issues | |
| 19:26:02 | tidwellr | sdague mriedem: https://bugs.launchpad.net/nova/+bug/1693335 | |
| 19:26:02 | openstack | Launchpad bug 1693335 in OpenStack Compute (nova) "UUID case sensitivity causing unfriendly and unexpected API errors" [Undecided,New] | |
| 19:29:13 | mriedem | thanks | |
| 19:33:28 | ckopper | Hi! I am new to nova and openstack development, so I apologize in advance if this is the wrong place to ask or if there is a certain procedure for this. I have a local use case for OpenStack where we want to use PCI passthrough for consumer GPUs which works well in principle. However the NVidia driver checks if it is run within a VM and refuses to load for consumer cards if you don't set a certain KVM/qemu flag (`kvm=off`). I have a local patch | |
| 19:33:28 | ckopper | that adds a flavor extra_spec `hw:hide_kvm` to set the correct options through libvirt and was wondering what the correct procedure to get this proposed for upstream was. | |
| 19:33:33 | ckopper | The patch itself is pretty trivial (mostly tests): https://gist.github.com/claudiok/5dd9fd01b9628e35f0b48884471e58cf | |
| 19:34:02 | ckopper | I assume this needs a spec and blueprint and then submission to gerrit for review but I thought I would check here first | |
| 19:34:16 | openstackgerrit | Sean Dague proposed openstack/nova master: WIP: request_id passing to neutron https://review.openstack.org/467242 | |
| 19:38:07 | mriedem | ckopper: lucky for you someone is already working on that https://review.openstack.org/#/c/459753/ | |
| 19:38:55 | ckopper | Haha - I have to admit I searched for this but apparently missed this review | |
| 19:39:08 | mriedem | sdague: yup, i have a functional test but b/c of sqlite, doing a GET /servers/id with upper-case returns 404 :( | |
| 19:39:35 | sdague | mriedem: yep | |
| 19:39:46 | mriedem | so, i'm not sure how to hack this | |
| 19:40:22 | sdague | so, there is the right way, which is figure out how to be able to run some tests against a mysql backend directly | |
| 19:40:32 | mriedem | i could stub the pull from the db to change the case on what is returned from the db so what's in the cache is different from what's in the request | |
| 19:40:40 | sdague | right, please don't do that | |
| 19:41:02 | sdague | honestly, any energy doing crazy stuff like that should be put into real mysql support in the test suite | |
| 19:41:23 | sdague | the biggest issue was the way the magic oslo.db stuff worked for that iirc | |
| 19:41:30 | mriedem | i'll poke | |
| 19:41:33 | sdague | it's honestly I think better to just ship the patch | |
| 19:41:40 | mriedem | maybe i can just extend test_base.MySQLOpportunisticTestCase | |
| 19:41:59 | sdague | mriedem: there was something weird about that when I tried | |
| 19:42:08 | melwitt | too bad there's not a sqlite pragma for that | |
| 19:43:32 | sdague | mriedem: https://review.openstack.org/#/c/283364/ that's a restore of an attempt to go down that path | |
| 19:43:39 | sdague | maybe it was working, but the fix never landed | |
| 19:44:04 | sdague | mriedem: the issue was about tricking engine fascade I think | |
| 19:44:39 | mriedem | trying it | |
| 19:44:42 | sdague | mriedem: anyway, that might be useful to build the pattern from | |
| 19:45:13 | mriedem | which mysql package do we need? | |
| 19:45:16 | mriedem | mysql-server? | |
| 19:46:10 | mriedem | bindep has both the server and client | |
| 19:46:16 | mriedem | but for some reason they fail to install on 16.04 | |
| 19:46:50 | mriedem | ah here we go | |
| 19:49:01 | ckopper | mriedem: concerning the img_hide_hypervisor_id feature: there one more flag that needs to be set to hide the hypervisor for Windows VMs (not necessary for Linux). (<hyperv><vendor_id state="on" value="FakeID"/></hyperv>). Is this something that should go into a separate patch or would it be appropriate to add this as a comment to the current code review? | |
| 19:49:18 | ckopper | (thanks again for pointing me to it!) | |
| 19:49:21 | mriedem | ckopper: please comment on the review | |
| 19:49:25 | ckopper | thanks | |
| 19:52:52 | mriedem | sdague: do you remember if you had to do any special creds tweaking with the mysql server or anything locally to get it to connect? | |
| 19:53:05 | mriedem | i thought there was a special userid/password or something | |
| 19:54:01 | mriedem | ah | |
| 19:54:01 | mriedem | For the opportunistic testing you need to set up db's named 'openstack_citest' | |
| 19:54:01 | mriedem | with user 'openstack_citest' and password 'openstack_citest' on localhost. | |
| 19:55:42 | sdague | yep, that | |
| 19:55:50 | mriedem | also, tools/test-setup.sh | |
| 19:58:28 | cdent | mriedem, sdague, melwitt (whatever other cores are around): this https://review.openstack.org/#/c/456198/ is a fix to tooling used by the placement api-ref that makes the tooling work with multiple inc files instead of just one monolithic file. getting it merged will allow some placement api-ref work to proceed more easily without needing to be in the same stack | |
| 19:59:08 | sdague | +2 | |
| 19:59:19 | cdent | thanks | |
| 20:01:11 | cdent | thanks melwitt and dansmith | |
| 20:01:30 | dansmith | two +Ws means you skip the gate I think | |
| 20:01:35 | cdent | \o/ | |
| 20:01:43 | melwitt | heh, secret code | |
| 20:08:28 | mriedem | sdague: EngineFacadeFixture isn't in nova, is that part of your patch series somewhere? | |
| 20:09:26 | mriedem | huh removed here | |
| 20:09:27 | mriedem | https://review.openstack.org/#/c/434843/2 | |
| 20:10:45 | sdague | mriedem: yeh, so I guess there is an oslo.db solution now? | |
| 20:10:51 | mriedem | yeah looking at ReplaceEngineFacadeFixture | |
| 20:12:54 | mriedem | it at least connected to my local mysql server which is progress | |
| 20:15:41 | melwitt | dansmith: is this true that online_data_migrations runs in the background after the command exits? someone working on a man page entry https://review.openstack.org/#/c/464634 | |
| 20:15:54 | dansmith | no | |
| 20:16:20 | melwitt | okay, I didn't think so | |
| 20:16:21 | mriedem | there is no scheduling | |
| 20:16:24 | mriedem | or queueing | |
| 20:17:13 | dansmith | which is kinda the point | |
| 20:18:01 | openstackgerrit | Kevin Benton proposed openstack/nova master: WIP: Bulk query floating IPs in _nw_info_get_ips https://review.openstack.org/465792 | |
| 20:21:14 | mriedem | i'm lost as to how to use the oslo.db opportunistic test fixture stuff | |
| 20:24:17 | melwitt | this is all I found about it https://specs.openstack.org/openstack/oslo-specs/specs/kilo/long-lived-transactionalized-db-fixtures.html#opportunistic-urls | |
| 20:26:04 | sdague | mriedem: if you put up a partial patch, I might play in the morning | |
| 20:27:30 | mriedem | ok yeah b/c i'm going to have to give up on this soon | |
| 20:28:17 | sdague | that's fine, having something to chew on over coffee in the morning is usually useful | |
| 20:42:58 | mriedem | zzzeek: i'm strugglying trying to use OpportunisticDBTestMixin to get a mysql-backed test running | |
| 20:43:19 | mriedem | i've got a test extending OpportunisticDBTestMixin and defining FIXTURE = test_fixtures.MySQLOpportunisticFixture | |
| 20:43:26 | zzzeek | mriedem: OK...are there no existing tests using it? | |
| 20:43:28 | mriedem | but teardown complains about not having a schema attribute on the test | |
| 20:43:30 | mriedem | nope | |
| 20:43:33 | mriedem | well, | |
| 20:43:48 | mriedem | our db schema migration tests do some stuff, but i can't make heads or tails of those | |
| 20:44:13 | mriedem | going through the setup code in oslo.db totally gets me lost | |
| 20:44:29 | zzzeek | mriedem: yeah | |
| 20:44:42 | zzzeek | mriedem: are you mixing in test_fixtures.OpportunisticDBTestMixin, | |
| 20:44:42 | zzzeek | oslo_test_base.BaseTestCase ? | |
| 20:44:57 | mriedem | not the BaseTestCase | |
| 20:45:25 | zzzeek | mriedem: try sticking "SCHEMA_SCOPE=None" on your test class ? | |
| 20:46:15 | mriedem | trying it | |
| 20:46:36 | zzzeek | mriedem: hmmm that's not it | |
| 20:46:40 | zzzeek | mriedem: stack trace ? | |
| 20:48:13 | zzzeek | mriedem: oh. this is all deprecated stuff anyway. you on newish oslo.db ? | |
| 20:48:21 | mriedem | yeah i'm trying to use the fixtures | |
| 20:48:22 | zzzeek | mriedem: e.g. dont need to backport to mitaka ? | |
| 20:48:33 | mriedem | with our nova base TestCase code | |
