therveHeya19:16
therveNew falcon release broke Zaqar19:16
therveShould we cap falcon or can someone make the migration quick enough?19:21
vkmcops19:23
vkmcI think we should cap it for now19:23
vkmcwhat is making it fail?19:24
therveThe hook system has been removed19:24
thervecap will take a long time to propagate, but well...19:25
vkmchmm19:26
vkmcgosh is a huge problem19:26
vkmcwe use hooks for everything19:26
therveWell indeed, but only at one place19:26
therveLet me have a quick look :)19:26
vkmcoki19:28
openstackgerritThomas Herve proposed openstack/zaqar: Move to falcon middleware  https://review.openstack.org/31573719:34
thervevkmc, ^^^ that seemed easy enough, but waiting on the local tests to finish19:35
therveThat seems good :)19:37
therveryansb, flwang, flaper87 ^^^ please have a look, it will unblock heat gate19:38
therveThanks!19:38

flwangtherve: i noticed that, but your hand is always faster than me.21:26
flwangflaper87: around?21:30
stevebakerflwang: therve is probably gone for the day, I can pick up any heat thing if necessary21:31
flwangdo you guys think if we need a spec for the sqlalchemy db migration support?21:31
flwangstevebaker: hello stranger :)21:31
flwangi even don't know you're in this channel21:31
stevebakerflwang: just joined - I should probably stay :)21:31
flwangstevebaker: pls stay around :) so that we can easily book a coffee time around wlg21:32
stevebakerflwang: +121:32
flwangare you living in CBD around?21:33
*** ametts has quit IRC21:33
stevebakerflwang: I was talking to Xav about Zaqar/Mistral integration - I suggested that would be a good thing to happen under your roof21:33
stevebakerflwang: I'm out beyond the airport, but do come into town on occasion21:34
flwangstevebaker: exactly, there are a lot of interesting things could happen with zaqar + mistral21:34
flwangstevebaker: ah, i see where you are21:34
flwangstevebaker: btw, are you aware any production case for autoscaling? based on heat21:36
stevebakernot specifically21:37
flwangstevebaker: got, thx21:39
stevebakerflwang: I mean I support plenty of production heat things which do *scaling* without the auto21:39
stevebakerflwang: by plenty I mean heat deploying openstack21:40
flwangstevebaker: i see, i'm just wondering if the heat+aodh is ready to go for prod21:42
stevebakerI see know reason why it is not ready for some production autoscaling cases. Having said that we'd like to move towards an architecture where aodh/whatever generates a zaqar message which triggers a mistral workflow that does a heat stack update21:45
stevebakerflwang: autoscaling was one of those things which we ended up implementing within heat because no other service offered it, and we've been trying to get it out ever since ;) Senlin grew out of that desire too21:47
flwangstevebaker: ah, so the autoscaling may be moved out of the scope of heat, right?21:51
stevebakerflwang: heat can always handle the scaling, but needing to signal heat directly to trigger *auto* scaling is something we'd like to move away from - because it means implementing a bunch of workflow-type logic that really doesn't belong in a declarative tool like heat21:54
stevebakerhence our grand heat+mistral+zaqar vision21:54
flwangi see, it make much sense21:54
flwangstevebaker: any spec/etherpad for that?21:55
flwangis there any overlap with senlin's roadmap? i know senlin's is trying to integrate with zaqar as well21:56
stevebakerflwang: hmm, not that I'm aware of, you should talk to zaneb about the architecture21:57
flwangstevebaker: awesome, thanks for the info21:57
flwangstevebaker: personally, i'm really interested in the role of zaqar in autoscaling21:57
stevebakerflwang: senlin is in the mix. senlin scales $things. Sometimes those things will be heat stacks, some times nova servers directly. Sometimes heat will be driving senlin via the senlin resource (or senlin backed (auto)scaling) resources. What the autoscaling workflow does will depend on whether the cluster was created via heat or directly to senlin22:00
stevebakerflwang: the point is that the thing which generates the autoscaling data shouldn't care, and neither should senlin or heat - all that logic is in the workflow22:01
flwangstevebaker: can i say that if senlin doesn't/won't leverage mistral then it has to keep a lot of workflow to make things happen, right?22:02
stevebakerflwang: hmm, good question. I've not looked closely at where they are at currently22:03
flwangstevebaker: i'm talking with zaneb, would you like to join? in heat channel22:06

tqtranflwang: I dont see a method in zaqar-client for updating queue's metadata. am i missing something?22:48
flwangtqtran: for v2?22:48
tqtranyeah, looking in here, https://github.com/openstack/python-zaqarclient/blob/master/zaqarclient/queues/v2/client.py22:48
flwangtqtran: we have done the code, and we need to release a new client version asap22:48
flwangtqtran: the code is in v1, the base,  https://github.com/openstack/python-zaqarclient/commit/3152321c7ab8be1828432a0c39083db05dd6a35522:49
tqtranah, thanks for the pointer22:50
tqtrani believe this is incorrect then? https://github.com/openstack/zaqar-ui/blob/master/zaqar_ui/api/zaqar.py#L7822:51
tqtranok the method did actually make a call through, but theres a bug with it23:13
tqtranhttps://github.com/openstack/python-zaqarclient/blob/master/zaqarclient/queues/v1/core.py#L10523:13
tqtranreturns None when it should return a proper object23:13
flwangtqtran: sorry, was in a meeting23:33
tqtrannp, still trying to figure out why the metadata is not persisted23:33
tqtrani filed a bug23:34
tqtranso hopefully one of your folks will know what is going on23:34
flwangtqtran: bug link?23:34
flwangEva-i: ping23:34
Eva-iflwang: pong23:35
flwangEva-i: are you working on  the lazy queue for subscription?23:35
flwangEva-i: i would like to get it in N-123:35
tqtranhttps://bugs.launchpad.net/zaqar/+bug/158125323:35
openstackLaunchpad bug 1581253 in zaqar "Updating the queue's metadata in the ui does not work" [Undecided,New]23:35
flwangif you're not, would you mind me taking over?23:35
flwangtqtran: thanks :)23:36
flwangtqtran: btw, is there anything we need to do for the subscription part?23:36
tqtranwhen listing the queue, is the metadata included? im not sure it is atm23:36
Eva-iflwang: no, not working. But it's easy to implement. So I'll try to upload patch for this soon.23:36
Eva-iflwang: I want to do it23:36
tqtranflwang: im going to send an email to david_cu_ about it, i think he might be going on vacation soon so i can take over the work23:37
flwangEva-i: ok, the deadline of N-1  May 30-03 R-18 newton-1 milestone23:37
flwangso we have 2 weeks23:37
flwangtqtran: cool23:38
Eva-iflwang: cool, more than enough23:38
flwangtqtran: so for the update metadata bug, i think we just need a new version of zaqar cleint23:38
flwangcan you try to pull the latest code? and if that works, i will release a new version of zaqarclient asap23:39
flwangEva-i: and may i know what's the status of install guide?23:39
tqtranflwang: i did pull in the latest. not sure why the metadata isnt showing up23:39
tqtrani'll dig around and see why it is missing23:40
flwangtqtran: oh, ok, then i will give it a try, thanks23:40
Eva-iflwang: I wonder if it was a good decision to do this patch: https://review.openstack.org/#/c/286433/. On first glance the idea sounded great. Now I'm not sure with our new queue PATCH method.23:40
flwangtqtran: so when you say 'pull the latest', did you mean using git pull or pip install ?23:40
tqtrangit pull23:40
flwangtqtran: ok23:40
tqtrani have a symlink in my venv to both zaqar and zaqarclient23:40
tqtranso its always up to date23:41
flwangtqtran: cool23:41
flwangEva-i: what's your concern?23:41
Eva-iflwang: status of install guide: I improved it much, but I'm stuck. I want to include in this guide autostart Zaqar info (creating systemd service with zaqar). I created such service, but it doesn't work.23:42
Eva-iflwang: but I haven't played enough with it23:42
flwangEva-i: could we get a shape quickly and improve the details later?23:43
Eva-iflwang: okay, yes, I can omit creating service.23:44
flwangEva-i: awesome, thanks23:44
Eva-iflwang: I'm stuck also with SSL. The old install guide suggests using Zaqar without SSL and I want to fix this. https://review.openstack.org/#/c/112655/1/doc/source/installing.rst23:44
flwangEva-i: what's your concern about https://review.openstack.org/#/c/286433/?23:44
*** amitgandhinz has joined #openstack-zaqar23:45
Eva-iflwang: mmm, no concern now, my mistake.23:48
stevebakerflwang: I don't see https://review.openstack.org/#/c/314412 or any zaqar change in http://status.openstack.org//zuul/23:48
*** amitgandhinz has quit IRC23:49
flwangstevebaker: oh, yep, thanks for the heads up23:49
flwangEva-i: btw, would you mind reviewing this https://review.openstack.org/#/c/315737/ ?23:50
flwangwe need to get it in asap, which is breaking the gate23:50
flwangEva-i: if you're happy the change, pls approve it directly instead of waiting the silly py34 job23:50
Eva-iflwang: I reviewing this patch and my local py34 tests failed because of well known infinite loop. But everything seems to be okay, manual test passes.23:55
Eva-iflwang: okay, I'll approve it23:55
Eva-iflwang: oh, look at this: "test_post_to_non_ascii_queue" in http://logs.openstack.org/37/315737/1/check/gate-zaqar-python34/7d38be0/testr_results.html.gz23:58
Eva-iflwang: maybe this patch is not enough to fix all incompatibilities of the new falcon lib version23:58
