PaulMurraybauzas, https://review.openstack.org/#/c/240159/09:37
bauzasPaulMurray: there is no reverify09:37
bauzasPaulMurray: so, when the gate fails, you have to go back to the queue check09:37
PaulMurraybauzas, really - did that change?09:37
bauzasto the *check pipeline09:38
PaulMurraywe used to reverify09:38
bauzasPaulMurray: yup, I don't remember exactly when, but if you see -infra, they should tell you that reverify now equals recheck09:38
bauzasPaulMurray: unless something changed again, and them me being just a douchebag09:38
PaulMurraybauzas, in that case I take it back - ignore me09:39

PaulMurraybauzas, from docs: 'To re-run check or gate jobs, leave a comment on the review with the form “recheck”.'09:47
bauzasPaulMurray: while the gate only triggers when +W https://github.com/openstack-infra/project-config/blob/59ffe6ed2015bab990c8d8c05580e2fe173b2085/zuul/layout.yaml#L48-L5609:47
PaulMurraynot that I rely on docs, but it supports your statement09:47
bauzasso reverify is still available, but if you see the above link, it only triggers a check run, not a gate tun09:48

mdboothbauzas: Hey, thinking about that aggregate thing, is there any way we can pass state between invocations of a filter for different hosts?10:59
johnthetubaguymdbooth: not really, mostly you end up creating a new filter that looks at both things at once11:00
mdboothThat way, I could simply retrieve the required info for all hosts when it is first requested, then subsequently return it from a cache11:00
tangchen_Hi, there is an api meeting in about an hour here, right ?11:00
mdboothjohnthetubaguy: This would be invocations in a single scheduler request11:01
*** haomaiwa_ has quit IRC11:01
mdboothI don't know if that makes any difference11:01
bauzasmdbooth: the HostState is a mutable object I feel, so you could probably end up touching something which would be passed over the second filter call, but that sounds an hack11:01
*** baoli has quit IRC11:01
*** haomaiwang has joined #openstack-nova11:01
johnthetubaguymdbooth: yeah, you could just hide it in the host state, as a cache, do you have an example of what you mean?11:01
*** EinstCrazy has joined #openstack-nova11:01
johnthetubaguyI mean, a pointer to the expensive code11:02
mdboothjohnthetubaguy: Actually this is in Icehouse and it's gone upstream11:02
mdboothThere's an expensive query which still exists in master, though11:03
bauzasjohnthetubaguy: so the problem is that we potentially idenfied an underperformant query in the Aggregate object layer11:03
mdboothBut the real problem is that in Icehouse we were executing it for every compute host11:03
*** emagana has quit IRC11:03
*** aysyd has joined #openstack-nova11:03
bauzasyeah that11:03
mdboothSo, we're really looking for an expedient backport11:03
bauzassince the isolate-sched-db BP, we alleviated the problem by caching the values in the HostManager11:04
*** marcusvrn_ has joined #openstack-nova11:04
bauzasbut we potentially still have a performance problem on master11:04
bauzasjohnthetubaguy: https://github.com/openstack/nova/blob/master/nova/objects/aggregate.py#L192 is the one we feel is underperformant11:05
mdboothI was just thinking about retryfilter, which seems to have some state11:05
*** dims has joined #openstack-nova11:05
mdboothHowever, given that this is persistent across re-invocation, I'm assuming that it's actually stored somewhere11:05
mdboothRather than just being an ephemeral in-memory dict11:06
mdbooth(which is what I really want)11:06

*** bharath_ has quit IRC11:07

bauzasmdbooth: so, given it's performance issue, maybe logging a bug explaining that https://github.com/openstack/nova/blob/master/nova/objects/aggregate.py#L192 sucks could be worth it11:09
bauzasbut I don't really see an actionable item for fixing the scheduler bits in master given we already have tha in memory11:09
*** rfolco has joined #openstack-nova11:10
mdboothRight. So the AggregateList stuff looks suspect to me in that context.11:10
bauzaswe should rather see how to make sure that  db.aggregate_get_by_metadata_key isn't underperforming11:10
mdboothBecause what we really want is a list of aggregate hosts, not aggregates11:10
*** deepakcs has quit IRC11:10
mdboothWe want: give me a list of aggregate hosts, and their relevant metadata, which conform to X11:10
bauzaswell, it gives you a list of Aggregates, right?11:10
mdboothYes, it does, but that's presumably because the logic is a bit backwards.11:11

mdboothI'm wondering if it's worth creating a new api for use there. Then I could backport that.11:14
bauzasmdbooth: https://github.com/openstack/nova/blob/master/nova/scheduler/host_manager.py#L347-L38111:14
mdboothLooking, thanks11:14
bauzasmdbooth: so, we call init_aggregates when loading the HostManager11:14
bauzasmdbooth: and then, the CRUD operations are mapped to the scheduler RPC API so that any operation to an aggregate on the REST API ends up notifying the scheduler(s)11:15

mdboothjohnthetubaguy: Well, the new code doesn't need to do that any more, as it doesn't query the db at all.11:24
mdboothI was thinking that I might do that for Icehouse, though, and the new code might be an upstream user.11:25
mdboothHowever, it doesn't look like that particular query is required any more.11:25
johnthetubaguyOK, this is for icehouse... thats why was getting confused11:26
*** otter768 has quit IRC11:26
johnthetubaguymaybe for that case, just try make sure you only make the DB call once, and hide it in the host state somewhere11:26

openstackgerritAnusha Ramineni proposed openstack/python-novaclient: Fix AttributeError raised from output of nova host-list  https://review.openstack.org/24354011:27
johnthetubaguymdbooth: I thought that stuff was only stored in memory, FWIW, which if you use the caching scheduler driver, is probably good enough11:27
mdboothHowever, there's still the weird situation that AggregateList.get_by_host returns an incomplete object11:27

*** markvoelker has joined #openstack-nova11:27

jaypipesbauzas: heh. I wasn't aware that we hard-code the scheduler process to be db_local. :( why do we do that?14:35
bauzasjaypipes: because the indirection API is only used by the compute nodes - not really getting the whole story of that but I guess it's also because we don't want another hop14:35
dansmithit would be super expensive for the scheduler to use the bus too, I would think14:36
bauzasjaypipes: for upgrades, we consider to only upgrade the whole controller, so I guess it's also why an indirection isn't necessary - but I defer the reasoning to anyone else :)14:36
danpbdansmith: rlrossit ok, so if we don't need to tie them together, lets clean that up as a separate patch, rather than a side-effect of some other patch that happens to be changing that object14:36
dansmithdanpb: sure14:37
jaypipesdansmith: was the scheduler *originally* using an indirection API?14:37
dansmithbauzas: using objects instead of direct-to-db would be good anywhere we're not so we have the option14:37
*** angular_mike_ has joined #openstack-nova14:37
dansmithjaypipes: not that I know of14:37
bauzasactually, we're using o.vo objects so it's just a matter of allowing deployers to have an indirection or not14:38
dansmithbauzas: right, okay, that's what I thought14:38
bauzasbecause AFAIK, there is no longer direct calls to the DB done by the scheduler14:38
bauzasbut rather, use of objects14:38
jaypipesbauzas: except hosts_up(), where the scheduler is still doing a db.service_get_all()14:38

PaulMurraydansmith, I was thinking that the operations on the compute host were synchronized, but they are not - only attach17:07
PaulMurraydansmith, I found this https://bugs.launchpad.net/nova/+bug/127514417:07
openstackLaunchpad bug 1275144 in OpenStack Compute (nova) "Volume operations should set task state" [Low,Confirmed]17:07
PaulMurrayI think it would be a good idea to add the task states for volume operations anyway - as you suggested17:07
PaulMurraywhat do you think?17:07
*** dane-fichter has joined #openstack-nova17:08
dansmithPaulMurray: yeah, probably17:08
PaulMurraydansmith, I see your problem about old compute hosts17:08
*** salv-orlando has quit IRC17:08
PaulMurrayany thoughts?17:08
dansmithPaulMurray: not really, other than doing something like checking the rpc version and some intent and failing if we can't do it17:09
dansmithwe could use service version for this too17:09
PaulMurrayhave you done anything like this before?17:09
dansmithwhere we look up the service version of the host we care about and then gate it that way17:09
dansmithPaulMurray: not really, no.. adding things like task states is fairly rare17:09
*** burgerk has quit IRC17:10

PaulMurrayfor the specs - the specs would depend on getting the bug done - does that sound ok or a bit iffy17:12

mriedemalaski: dansmith: ^17:39

dansmithmriedem: no, I just noticed that it could happen while reviewing a spec17:39
dansmither, melwitt ^17:39
dansmithmelwitt: there would be no specific trace from the poll itself, but it could just cause general nastiness if it raced with another thing, and the failure would likely be in that path17:40
dansmithmelwitt: I can open a bug for "this could break" if you like :)17:40

mriedemdansmith: so it looks like the ovo fixture's test_relationships would be OK with just sub-object traversal, but test_relationships_in_order requires that obj_relationships be used, and i don't think cinder was using those (just child_versions)19:35
dansmithmriedem: I think cinder should drop their use of child_versions entirely, since they don't need/use them and if they ever start needing it, they'd be using the new methods I think19:36

dansmithalaski: when we talked about this at summit I was pro keeping the changes field21:34

*** sfinucan_ has quit IRC21:35

dansmiththey are stable in that they must be one of the fields named in the data blob21:35
*** rk4n has quit IRC21:35
*** baoli has quit IRC21:38
alaskiyeah.  My concern is just that there will be two similar notifications one with ['disabled'] and another with ['disabled', 'disabled_reason'] as changed fields and consumers will do different things.  I'd rather our signals were more explicit21:40
*** changbl has quit IRC21:41
alaskiactually, I just recalled that we have a use case that desires instance updates with changed_fields specified21:41
*** lpetrut has joined #openstack-nova21:41
alaskiokay, I'm on the pro side for now21:42
*** hwoarang has joined #openstack-nova21:43
alaskiwhat we would really want is not just the end state and a list of changed fields, but the start and end states for the changed fields.21:44
*** dustins has quit IRC21:46
dansmithalaski: are you saying that we would want two notifications, one for disabled and one for disabled_reason?21:47
dansmithif we're setting those together, I'd expect one notification with both fields mentioned as changed21:47
alaskino, not that.  they should be in one notification21:47
alaskiit's not super helpful for disabled or the reason, but what would be nice for something like instance.task_state would be changed_fields: ['task_state'], task_state: spawning->scheduling21:49
alaskialthough in an easier to parse format21:49
dansmithyeah, that's a little harder21:49
dansmithare you saying you think we should require that of this spec?21:50
dansmiththe problem with that is that the spec wants to include the serialized object form, which doesn't include that21:50
*** abitha has joined #openstack-nova21:50
*** devl_ has quit IRC21:50
alaskino.  but I have some concern about not having a larger conversation about notification formats and just piggybacking on objects21:50
dansmithI guess you could argue that we not include the changes, and then include the actual changed fields in richer format in the notification itself21:51
*** Marga_ has joined #openstack-nova21:51
dansmithwell, we kinda had that at the last midcycle and again at the summit just now21:51
dansmiththe other thing to think about here,21:52
dansmithis that this goes hand in hand with the versioned notifications stuff,21:52
dansmithwhich intends to create a wrapper Notification object,21:52
dansmithwhich will have the instance (in this example) inside, but will also have fields of its own,21:52
dansmithso we could have a DictOfListOfStrings, where that contained something like: {'task_state': [None, 'scheduling']}21:53
dansmithwhich could list each thing and the transitions21:53
alaskiAnd the notification object would be versioned separately from the wrapped object?21:54

*** ccarmack has quit IRC22:06
*** electrocucaracha has joined #openstack-nova22:06
gibialaski, bauzas: the dependencies are a bit mixed after the summit. We agreed on Friday that notification for service status change can go in before the complete versioned notification api implementation22:07
gibito serve as a carrot for the ops to move into the new versioned api22:07
bauzasgibi: okay, then I missed that point, since your spec was providing a dehydrated object22:08
gibibauzas: the new service status change notification will use o.vo for the payload but it will not give the full impl of the versioned notification api (no sample generation, no documentation) that will be fixed as the first step of the versioned notification api work. (I know it sounds complicated :))22:09
alaskigibi: what I'm trying to figure out is how to get from serialized status object to a status object within a notification object22:10
*** salv-orlando has joined #openstack-nova22:10
gibialaski: hm, good point, this needs to be fixed in the spec. We shall emit a serialized Notification object and in that object include the serialized service object22:12
gibithis is needed to be compatible with the versioned notification api spec22:12
*** salv-orlando has quit IRC22:13
