ryansbcheck them out and let me know what you think :)01:07
flwangryansb: cool, reviewing....01:17
flwangryansb: looks good for me, thanks for the improvement01:20
flwangi'm always frustrating with my english :D01:20
ryansbno worries. When do you want to submit it? I'd like to go over it again in the morning with fresh eyes, and we can get vkmc to look at it as well01:22
ryansbIt's due midnight PST at the end of Feb 1, so you can look it over in (your) morning before submit-time01:23
ryansbsound good?01:23
Eva-iHello. Do you know when the design summit deadline for proposing design sessions will be?01:30
ryansbno, I don't01:31

Eva-iflwang: seems like it01:46
Eva-iflwang: I have some ideas how to make Zaqar more stable. Maybe I should propose something for the design summit and try myself as design session lead. I wonder if it will be a good idea, since I have never attended to summit and don't know many things.01:50
flwangEva-i: sure, sounds a good plan.01:51
Eva-iflwang: oki01:51
flwangEva-i: does your internship provide the funding for this kind of travel?01:51
*** boris-42 has quit IRC01:53
Eva-iflwang: from what I know, yes, internship can give me $500. Maybe OpenStack can also add some.01:56
flwangEva-i: cool, just apply for the funding from openstack foundation at the first time :)02:00
Eva-iflwang: yes, I will =)02:03

ryansbflwang1: not meeting related, but if you want to take a final look over https://www.openstack.org/summit/austin-2016/call-for-speakers/manage/7096/speakers I'm ready to submit it15:53
flwang1ryansb: i did, go for it :) thanks15:54

flwang1i'm running to bed, ttyl, guys16:00
Eva-iflwang1: see you16:00
ryansbnight, flwang116:00
ryansbvkmc_: I'm going to go ahead and submit that talk. That ok with you?16:00
vkmc_sure thing :)16:01
Eva-iI'm still thinking about pool/flavor PUT. Seems like the way PUT method is implemented in Zaqar is good. Maybe instead of modifying PUT method, we should introduce POST method? =)16:01
*** ametts has joined #openstack-zaqar16:01
ryansbEva-i: so you're saying keep the current PUT behavior, but add a POST endpoint that will raise conflicts when creating a duplicate-named queue16:02
Eva-iryansb: exactly16:02
Eva-iThis would be backward-compatible and the problem would be solved. The user who is concerned about not overwriting existing resources, would just use POST method instead of PUT.16:03
ryansbEva-i: can you make a spec for it? I'd like to give folks a chance to comment. Sounds like a good idea to me16:03
ryansbbig thing there would be documenting the difference between the two so users know why they would use one or the other16:03
Eva-iryansb: I think it would be pretty easy to document.16:05
ryansbyeah, just saying we'd have to make it really obvious for users16:06
ryansbflwang1: vkmc_ : sent proposal, now we wait16:09
vkmc_yaaay16:10
vkmc_thanks ryansb16:10
Eva-iryansb: okay, I'll make a spec. If it will be approved, it would be a bit sad, because mdnadeem put much effort into spec about PUT method improvement. He even wrote two patches for it.16:10
ryansbshould have a confirmation email in your inbox16:11
Eva-iryansb: you are going to be speaker on the summit?16:12
ryansbEva-i: flwang&vkmc&I are proposing a talk, so we hope to be16:13

flwangvkmc: Zaqar - Implement support for binary data in the websocket transport is being implemented by Eva-i :)21:03
vkmcyeah, it has the date at the bottom21:04
vkmcwe have to clean that up21:05
flwangvkmc: cool, i will add myself :)21:08
vkmcgreat21:08
flwangvkmc: thanks for driving this21:08
Eva-iflwang: good morning. I just made a mistake. When I was editing wiki page, I asked someone if API v2 is stable or not, I don't remember who. I got the answer "unstable" and edited wiki page accordingly. You and vkmc approved new wiki and after this I started to really believe that API v2 is unstable.21:09
Eva-iFor me unstable doesn't means issues. It's just a word telling the users that something still can be changed in API in a backward-incompatible way.21:09
Eva-i*doesn't mean21:09
flwangEva-i: pls let me know the wiki link21:10
Eva-iAlso, if we merge this patch https://review.openstack.org/#/c/273931/, it would be backward-incompatible change for our API v1.1 and API v221:10
*** davideagnello has joined #openstack-zaqar21:10
flwang'unstable' is a horrible word for operation guys21:10
Eva-iflwang: https://wiki.openstack.org/wiki/Zaqar see Zaqar RESTful API Specs21:11
flwangEva-i: you mean the rename from pool to pool_group?21:11
Eva-iflwang: yes21:12
flwangyep, it does, but i would like to fix it since it's really really confused21:12
Eva-iflwang: yes, I find it very confusing too =)21:13
flwangEva-i: i'm not aware if there is a clear guide for the api change, so we generally discuss them case by case21:13
Eva-iflwang: there is http://specs.openstack.org/openstack/api-wg/guidelines/evaluating_api_changes.html21:13
flwangif it's bug, a really issue, then we should fix it21:13
Eva-iflwang: there is also a chat dedicated for discussing openstack APIs somewhere21:14
flwanggood link21:14
flwangi will review it21:14
flwangback to the change pool -> pool-group21:15
flwangit needs to be fix, but I don't mind a vote :)21:15
Eva-iI guess, the most right decision is to make API v3. But, as you said, there's not much users of Zaqar now. If not much people are relying on Zaqar API, the change can be made, I guess. But flaper87 would be sad. =)21:17
Eva-i*there are not much users21:18
*** rcernin has joined #openstack-zaqar21:18
flwangEva-i: NOOOOOOOOOOOOOOOOO21:18
flwangpls don't mention v321:18
Eva-iflwang: :o21:19
flwanghah21:19
Eva-iflwang: okay, okay, calm down =)21:19
flwangin glance, we released v3 even v2 hasn't been adopted by Nova21:20
flwangit's not a good practice and i don't want to see it in Zaqar21:20
Eva-iflwang: I agree, it's not good to do it now. But next time, if we will ever be working on the next version, we better test it thoroughly before declaring it as officially released.21:24
flwanghaha21:30
flwangEva-i: it's like a words from new graduate21:30
Eva-i=)21:30
flwangEva-i: even a software of rocket, there is bug, agree?21:31
flwangso my point is you can't guarantee a bug-free software21:31
Eva-iflwang: yes21:34
Eva-iflwang: here's lovely bug for you https://bugs.launchpad.net/zaqar/+bug/154059821:36
openstackLaunchpad bug 1540598 in zaqar "Subscription operations return wrong status codes when there are no pools." [Undecided,New] - Assigned to Eva Balycheva (ubershy)21:36
ryansbhehe, that'd be a good t-shirt "Certified, artisanal software: 100% bug-free"21:37
flwangryansb: if you made one, i will buy it :)21:38
flwangEva-i: as for bug/1540598, how can you create the subscription if there is no queue21:40
Eva-iflwang: see this: "create request returns 409 code". Seems like someone was able to do so. =)21:41

Eva-itherve: hello, have you received my email about websocket notifications?22:53
flwangtherve: if you can +1 on the patch, it could be speeded up :)22:53
therveEva-i, I did receive it! I even starred it, but it went over my head in the week-end22:54
therveEva-i, Do you have some time to chat about it now?22:54
Eva-itherve: yes, I would like to =)22:55
therveEva-i, So, can you explain what's your proposed solution?22:55
therveI think it has a flaw, but I want to be sure I understand it22:55
flwangand i'm around to eavesdrop the secret solution :)22:58
Eva-itherve: my proposal is to make Zaqar send websocket notifications directly, without sending them first as http requests and listening to them.22:58
therveEva-i, Right, so the problem here is that it works if you only have one Zaqar process22:58
Eva-itherve: I haven't figured out details, if it's possible or not. That's why I emailed you and asked, why have you implemented it that way it is now.22:59
therveEva-i, But any non-trivial deployment will have a cluster of load-balanced wsgi process22:59
therveOne websocket connection will only be on one server, but we want to received notifications from every other nodes22:59
therve(Note that I haven't tested it, so it's mostly theoretical, but it should work)23:00
therveEva-i, Even in the devstack deployment, websockets are connected to one process, but can receive notifications from the wsgi process23:01
therveSo you can send them "directly"23:01
therveSo you *can't* send them "directly"23:01
Eva-itherve: aha, I understand now what is the problem. I'll think about it.23:02
therveOK cool. Don't hesitate if you have other questions23:03
* therve off23:03
Eva-itherve: thank you!23:03
