vishy | soren: ping | 15:12 |
vishy | tr3buchet: ping | 15:12 |
comstud | i need soren too | 15:15 |
comstud | :) | 15:15 |
comstud | i have this eventlet patch | 15:15 |
comstud | for 771512 | 15:15 |
*** cweidenkeller has joined #openstack-dev | 15:20 | |
vishy | comstud: I looked at that patch, have you heard at all from the eventlet maintainer? | 15:21 |
comstud | the convo on the thread for the bug soren filed has stalled | 15:21 |
vishy | comstud: have you asked redbo to look at it? | 15:22 |
comstud | he only had a couple comments anyway | 15:22 |
vishy | he's done some eventlet patching as well | 15:22 |
comstud | no, i haven't. ok. | 15:23 |
comstud | i've never talked to redbo | 15:23 |
*** cweidenkeller has quit IRC | 15:25 | |
comstud | i'd been stuck in agent land too long, so there's a number of people i don't know | 15:26 |
comstud | happy to be able to focus on nova now :) | 15:26 |
vishy | comstud: redbo is on the swift team | 15:27 |
comstud | ah, mike barton | 15:29 |
comstud | cools, will ping | 15:29 |
vishy | comstud: also, notmyname just suggested taking it over to #eventlet to see if anyone there has suggestions | 15:30 |
comstud | good idea | 15:31 |
comstud | i think our real issue here is larger than this eventlet problem... | 15:32 |
comstud | even if this eventlet problem is real | 15:32 |
jk0 | vishy: pushed your changes | 15:32 |
*** cweidenkeller has joined #openstack-dev | 15:33 | |
comstud | so, i'd like to see eventlet get patched.. but at the same time, i have some changes to make to API | 15:33 |
comstud | playing around with this more today | 15:33 |
*** dprince has quit IRC | 15:34 | |
vishy | comstud: sounds good | 15:34 |
*** rnirmal has joined #openstack-dev | 15:37 | |
vishy | jk0: seems fine, but I have a question | 15:39 |
vishy | jk0: what is making the code block? | 15:40 |
jk0 | comstud might be able to answer that better than I can | 15:41 |
jk0 | it cropped up when running our tests (50-100 simultaneous builds) | 15:41 |
vishy | comstud: ?? | 15:42 |
jk0 | I can't remember what the exception was but comstud might | 15:42 |
vishy | jk0: the time.sleep should pause the greenthread and allow other greenthreads to move along | 15:42 |
jk0 | I think the problem was _find_host() happens before the cast | 15:43 |
vishy | sure, but there is a sleep in _find_host | 15:44 |
vishy | very odd | 15:44 |
jk0 | yeah.. I can't remember what it was | 15:44 |
vishy | ok maybe when comstud comes back he can enlighten me | 15:44 |
jk0 | yeah, I think the concern was API keeping the connection open until that was casted, but in some cases it could take up to 10-30 seconds | 15:45 |
*** AXiS_SharK has quit IRC | 15:45 | |
*** rnirmal has quit IRC | 15:46 | |
comstud | i don't have a real answer | 15:46 |
vishy | i see. But it will still take 10-30 seconds no? | 15:46 |
vishy | it will just be in a new greenthread | 15:46 |
comstud | i think we were just stressing the system enough... | 15:46 |
comstud | that it was taking a while for the DB to get updated with the compute node that was picked | 15:47 |
comstud | for a particular instance | 15:47 |
comstud | yes | 15:47 |
vishy | that explains the timeout, so the thing that is actually fixing it is raising the timeout to 30 | 15:47 |
vishy | spawning a new greenthread seems unnecessary in that case, no? | 15:48 |
comstud | i'd prefer not to make an API client user block unnecessarily | 15:48 |
comstud | if the event doesn't need to wait | 15:48 |
comstud | but | 15:48 |
vishy | comstud: but it isn't | 15:48 |
vishy | comstud: all the time is spent in monkey_patched calls | 15:48 |
vishy | so it isn't blocking | 15:48 |
comstud | yeah, i get that. that's not what i meant... | 15:49 |
comstud | take our control panel for instance... | 15:49 |
comstud | the call for build is going to sit there and wait | 15:49 |
comstud | until set_admin_password finds the host | 15:49 |
vishy | ah i see | 15:49 |
comstud | if for whatever reason that takes 20 seconds... | 15:49 |
comstud | yea | 15:50 |
vishy | ok so the purpose of the greenthread is so that the call can return immediately | 15:50 |
vishy | makes sense now | 15:50 |
comstud | yeah | 15:50 |
vishy | thx | 15:50 |
comstud | there's no data being returned that's dependent on that finishing first | 15:50 |
comstud | i don't necessarily like that there's a 2nd cast to set the password, though. | 15:51 |
comstud | long term, i think compute should handle this when it sees a spawn request | 15:52 |
*** rnirmal has joined #openstack-dev | 15:52 | |
vishy | comstud: yes, perhaps that should all be moved down into compute.manager | 15:52 |
comstud | that would kill this problem overall, and I think just makes more sense | 15:53 |
comstud | but anyway, the current fix works for now to get us to 50 builds at once | 15:54 |
comstud | i need 766404 reviewed again | 15:54 |
comstud | that's another important one related to this | 15:54 |

soren | vishy, comstud: Wazzup? | 18:25 |
soren | comstud: How about we take your eventlet patch and stick an updated eventlet in the PPA and see how it goes? | 18:26 |
comstud | that'd be cool | 18:27 |
lorin1 | Possibly stupid question: I'm trying to figure out what code actually invokes ComputeManager.run_instance. I see how a compute node gets scheduled in SimpleScheduler.schedule_run_instnace, but what code actually invokes the run_instance method? | 18:27 |
comstud | soren: did you look it over completely? i think it makes sense. | 18:27 |
soren | comstud: Haven't had the surplus brainpower to review it in detail, no. | 18:28 |
soren | comstud: The approach seems sound, though. | 18:29 |
comstud | no worries | 18:29 |
comstud | been exercising it pretty heavily | 18:29 |
comstud | so i think it's sound | 18:30 |
soren | I do wish upstream was more interested :-/ | 18:32 |
comstud | maybe if i do a real branch and do a pull request it'll get more attention | 18:47 |
comstud | what version is the current ppa based off of? | 18:48 |
comstud | i guess 0.9.14 | 18:49 |
comstud | there's a 0.9.15 now | 18:49 |
soren | I forget. | 18:49 |
soren | Yeah, 0.9.14 sounds right. | 18:49 |
