| 18:00:02 | jaypipes | zzzeek: which PG then barfed on | |
| 18:00:16 | zzzeek | jaypipes: yeah no, consumers.indexes is not changing itself when you drop those columns | |
| 18:00:19 | mordred | cdent, mriedem: the shade test patch is all green! | |
| 18:00:30 | jaypipes | zzzeek: hmm. ok. | |
| 18:00:42 | zzzeek | jaypipes: so, if you want *that*, do this: "from sqlalchemy import inspect; insp = inspect(migrate_engine); indexes = insp.get_indexes("consumers")" | |
| 18:00:44 | cdent | yayness. I think sdague said he's fast approve the devstack change | |
| 18:00:50 | mordred | although linuxbridge had a sad | |
| 18:01:27 | jaypipes | zzzeek: I think the simplest solution is to go back to revision 1 and do the execute(ALTER TABLE ... USING) thing for Postgresql? | |
| 18:01:38 | zzzeek | jaypipes: that will just give you names of indexes. if it were me I'd then just say "engine.execute("DROP INDEX <name>")", howver you can also say Index("myname").drop() | |
| 18:02:03 | zzzeek | jaypipes: I think it is yes. but all of these different scenarios can work, you're just having very bad luck stepping on every rake in the yard :) | |
| 18:02:23 | jaypipes | indeed :) | |
| 18:02:47 | zzzeek | jaypipes: try the USING with the conditional, i can make that or the other version work for you afte that | |
| 18:02:56 | zzzeek | jaypipes: you don't run mysql/pg functional tests locally ? | |
| 18:03:20 | sdague | that linuxbridge sad was a fail in test_device_tagging | |
| 18:03:34 | jaypipes | zzzeek: only mysql and sqlite, not postgreSQL, no... | |
| 18:03:34 | sdague | mriedem: that one being tracked yet, the error looks like it's going to be a race | |
| 18:03:43 | jaypipes | zzzeek: suppose I should :) | |
| 18:03:58 | zzzeek | jaypipes: it's just a yum install away... :) | |
| 18:04:15 | jaypipes | yeah yeah :) | |
| 18:04:35 | zzzeek | jaypipes: anyway I obv. have everythign running here so i can run through it later if you still cant get it working | |
| 18:04:58 | jaypipes | zzzeek: I'll just install PG :) | |
| 18:05:04 | zzzeek | jaypipes: OK. | |
| 18:10:19 | mriedem | sdague: huh? link? | |
| 18:12:33 | openstackgerrit | Merged openstack/nova master: Be more tolerant of keystone catalog configuration https://review.openstack.org/438049 | |
| 18:12:49 | mriedem | sdague: oh you mean this http://logs.openstack.org/42/471042/2/check/gate-tempest-dsvm-neutron-linuxbridge-ubuntu-xenial/4cc66aa/console.html#_2017-06-05_17_23_22_278409 | |
| 18:12:58 | mriedem | i'm not aware of a bug for that | |
| 18:13:13 | mriedem | dansmith: just leave it | |
| 18:17:54 | openstackgerrit | Doug Hellmann proposed openstack/python-novaclient master: strip the remote prefixes from the release note branch specifiers https://review.openstack.org/471082 | |
| 18:18:16 | sdague | mriedem: yeh - http://logs.openstack.org/42/471042/2/check/gate-tempest-dsvm-neutron-linuxbridge-ubuntu-xenial/4cc66aa/console.html#_2017-06-05_17_23_22_337560 | |
| 18:18:24 | sdague | I'll make a bug here in a minute for it | |
| 18:18:36 | sdague | there are a few hits on it | |
| 18:53:02 | sdague | \o/ for the diagnostics API standardization - https://review.openstack.org/#/c/355540/ | |
| 19:03:12 | openstackgerrit | Chris Dent proposed openstack/nova master: Fix ChanceScheduler returning a wrong node https://review.openstack.org/466725 | |
| 19:03:18 | mriedem | cool. a few wording things in there that could be cleaned up in a follow up change | |
| 19:04:09 | mriedem | now onto the novaclient change | |
| 19:06:10 | mriedem | cfriesen_: this is what you're waiting on btw https://review.openstack.org/#/c/471081/ | |
| 19:06:12 | openstackgerrit | Matt Riedemann proposed openstack/nova master: Replace messaging.get_transport with get_rpc_transport https://review.openstack.org/469659 | |
| 19:06:32 | cfriesen_ | mriedem: mriedem: cool, thanks | |
| 19:08:26 | cfriesen_ | mriedem: the empty lines are needed for the nested lists to get formatted properly? is that yaml or rst? | |
| 19:09:00 | mriedem | rst | |
| 19:09:19 | cfriesen_ | is the hyphen a formatting element in rst? | |
| 19:09:26 | mriedem | yeah | |
| 19:10:03 | mriedem | http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#bullet-lists | |
| 19:10:14 | cfriesen_ | got it | |
| 19:10:47 | efried | mikal Should https://review.openstack.org/#/c/4379/ have removed the ", by name (not ID!)" part of https://github.com/openstack/nova/blob/master/nova/virt/driver.py#L152 ? | |
| 19:12:16 | efried | or is there some reason we still need to enforce this lookup as being by name? | |
| 19:12:53 | mriedem | i will enjoy whatever answer mikal gives you for a thing done 5 years ago | |
| 19:13:50 | mriedem | oh, | |
| 19:13:59 | efried | Yeah, anyone should feel free to answer this. | |
| 19:14:00 | mriedem | and if/when he replies, make sure it's related to powervm :) | |
| 19:15:09 | efried | mriedem Since you asked, I was working on filling in a gap we missed in the in-tree impl: the only thing we populate in the InstanceInfo is the state. | |
| 19:15:36 | efried | While looking, I found that docstring and recognized that we've never looked that guy up by name (even in the out-of-tree driver). | |
| 19:15:58 | efried | So I went to figure out whether there was any basis for that edict. | |
| 19:16:29 | mriedem | remove ", by name (not ID!)" from the docstring | |
| 19:16:38 | efried | Doing it. Thanks. | |
| 19:16:38 | mriedem | it's always passed an Instance object | |
| 19:19:47 | openstackgerrit | Jay Pipes proposed openstack/nova master: placement project_id, user_id in PUT /allocations https://review.openstack.org/469634 | |
| 19:19:48 | openstackgerrit | Jay Pipes proposed openstack/nova master: placement: use separate tables for projects/users https://review.openstack.org/470645 | |
| 19:19:48 | openstackgerrit | Jay Pipes proposed openstack/nova master: placement: Add GET /usages to placement API https://review.openstack.org/469635 | |
| 19:20:04 | jaypipes | zzzeek: \o/ ^ | |
| 19:22:05 | openstackgerrit | Chris Dent proposed openstack/nova master: [placement] Use util.extract_json in allocations handler https://review.openstack.org/471067 | |
| 19:24:20 | openstackgerrit | Eric Fried proposed openstack/nova master: ComputeDriver.get_info not limited to inst name https://review.openstack.org/471106 | |
| 19:24:31 | efried | mriedem ^^ This is why I earn the big bucks. | |
| 19:26:51 | mriedem | return conn.lookupByName(instance.name) | |
| 19:26:51 | mriedem | efried: it probably all ties back to the libvirt driver using this to get the guest info | |
| 19:27:03 | mriedem | most things in the virt driver layer are libvirt-biased | |
| 19:28:24 | efried | mriedem Don't I know it. | |
| 19:31:13 | efried | mriedem The other thing I noticed is that the only two consumes of get_info (in manager.py) only ever use the state. Makes me less panicky about hurrying to populate those other fields. | |
| 19:31:29 | efried | consumers* | |
| 19:47:27 | efried | jaypipes I presume the resource tracking stuff never plans to use get_info to figure out how much e.g. cpu/mem a VM is consuming - you're just going to record that at claim time and go with it? | |
| 19:50:05 | dansmith | efried: we don't know how much memory a guest is consuming without introspection | |
| 19:50:37 | dansmith | efried: and the amount of cpu it's using at some instantaneous point is not really an allocation thing | |
| 19:51:03 | efried | dansmith Okay, fair; but are there any plans for nova to actually use those InstanceInfo fields? | |
| 19:51:20 | dansmith | those...instanceinfo...fields... | |
| 19:51:23 | efried | Perhaps I'm missing some duck-typed dynamic usage of get_info | |
| 19:51:58 | dansmith | there are remnants of the extensible resource tracker and metric info in nova.. perhaps you mean that stuff? | |
| 19:52:18 | efried | dansmith https://github.com/openstack/nova/blob/master/nova/virt/hardware.py#L213-L217 <== those InstanceInfo fields | |
| 19:52:44 | efried | dansmith Perhaps I do mean that stuff. What stuff do I perhaps mean? | |
| 19:53:43 | dansmith | yeah, I _think_ that stuff is only used for choosing numa nodes | |
| 19:54:43 | dansmith | or maybe not even that, I don't even see that stuff considered in the scheduler | |
| 19:54:52 | efried | dansmith Does that happen in the nova tree? I'm even grepping and not finding any consumption of those fields. | |
| 19:55:55 | dansmith | efried: I think it's all within that file, and all for things like picking cpu topologies and stuff | |
| 19:56:05 | dansmith | but not a generic thing for reporting or choosing whole compute nodes, AFAIK | |
| 19:56:14 | dansmith | definitely not the material of placement though | |
| 19:56:45 | efried | dansmith What I'm considering doing here is leaving my InstanceInfo so it just provides the state. If anything ever gets written to consume any of the other fields, and assuming those code paths get hit in some tempest test, our CI will catch it (by raising AttributeError). | |
| 19:57:29 | efried | And at that time, we can figure out how best to implement those fields. Cause there's a number of options, with different performance characteristics, one of which would be more appropriate than another depending on the actual usage. | |
| 19:58:23 | dansmith | sounds reasonable | |
| 19:58:31 | mriedem | https://review.openstack.org/#/c/133777/ | |
| 19:58:42 | mriedem | looks like it was added for something...but very little context | |
| 19:58:52 | dansmith | yeah | |
| 19:59:28 | cfriesen_ | weird python question....how is the "return" value from main() in cmd/manage.py expected to be consumed? | |
| 19:59:48 | cfriesen_ | it doesn't seem to have any effect on the process return value if run from the shell | |
| 19:59:49 | efried | Recently, too - but only relative to the aforementioned "by name (not ID!)" thing ;-) | |
| 20:02:14 | mriedem | goes back to https://github.com/openstack/nova/commit/19da125805eedbfcfd202abac4a90c57e6c538c4 | |
| 20:02:49 | mriedem | https://github.com/openstack/nova/blob/c8e8b44ef27e49b3986659ee0cb6bd77b38430d8/nova/virt/libvirt_conn.py#L797 | |
| 20:02:59 | mriedem | so, it just always returned that other crap | |
| 20:03:05 | mriedem | because we could | |
| 20:03:15 | mriedem | because the libvirt domain api gave it to us | |
| 20:04:00 | mriedem | https://github.com/openstack/nova/blob/c8e8b44ef27e49b3986659ee0cb6bd77b38430d8/nova/virt/xenapi/vm_utils.py#L686 | |
| 20:05:51 | efried | Dig. I'll go with the plan, then. I'll just add a comment explaining it, so my posterity doesn't do a tim-the-tool-man like I did. | |
