sandywalshttx soren sorry, got zip done on dev review duties yesterday. I'll try and make up for it over the next few days.14:45

vishysoren: ping15:12
vishytr3buchet: ping15:12
comstudi need soren too15:15
comstud:)15:15
comstudi have this eventlet patch15:15
comstudfor 77151215:15
*** cweidenkeller has joined #openstack-dev15:20
vishycomstud: I looked at that patch, have you heard at all from the eventlet maintainer?15:21
comstudthe convo on the thread for the bug soren filed has stalled15:21
vishycomstud: have you asked redbo to look at it?15:22
comstudhe only had a couple comments anyway15:22
vishyhe's done some eventlet patching as well15:22
comstudno, i haven't. ok.15:23
comstudi've never talked to redbo15:23
*** cweidenkeller has quit IRC15:25
comstudi'd been stuck in agent land too long, so there's a number of people i don't know15:26
comstudhappy to be able to focus on nova now :)15:26
vishycomstud: redbo is on the swift team15:27
comstudah, mike barton15:29
comstudcools, will ping15:29
vishycomstud: also, notmyname just suggested taking it over to #eventlet to see if anyone there has suggestions15:30
comstudgood idea15:31
comstudi think our real issue here is larger than this eventlet problem...15:32
comstudeven if this eventlet problem is real15:32
jk0vishy: pushed your changes15:32
*** cweidenkeller has joined #openstack-dev15:33
comstudso, i'd like to see eventlet get patched.. but at the same time, i have some changes to make to API15:33
comstudplaying around with this more today15:33
*** dprince has quit IRC15:34
vishycomstud: sounds good15:34
*** rnirmal has joined #openstack-dev15:37
vishyjk0: seems fine, but I have a question15:39
vishyjk0: what is making the code block?15:40
jk0comstud might be able to answer that better than I can15:41
jk0it cropped up when running our tests (50-100 simultaneous builds)15:41
vishycomstud: ??15:42
jk0I can't remember what the exception was but comstud might15:42
vishyjk0: the time.sleep should pause the greenthread and allow other greenthreads to move along15:42
jk0I think the problem was _find_host() happens before the cast15:43
vishysure, but there is a sleep in _find_host15:44
vishyvery odd15:44
jk0yeah.. I can't remember what it was15:44
vishyok maybe when comstud comes back he can enlighten me15:44
jk0yeah, 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 seconds15:45
*** AXiS_SharK has quit IRC15:45
*** rnirmal has quit IRC15:46
comstudi don't have a real answer15:46
vishyi see.  But it will still take 10-30 seconds no?15:46
vishyit will just be in a new greenthread15:46
comstudi think we were just stressing the system enough...15:46
comstudthat it was taking a while for the DB to get updated with the compute node that was picked15:47
comstudfor a particular instance15:47
comstudyes15:47
vishythat explains the timeout, so the thing that is actually fixing it is raising the timeout to 3015:47
vishyspawning a new greenthread seems unnecessary in that case, no?15:48
comstudi'd prefer not to make an API client user block unnecessarily15:48
comstudif the event doesn't need to wait15:48
comstudbut15:48
vishycomstud: but it isn't15:48
vishycomstud: all the time is spent in monkey_patched calls15:48
vishyso it isn't blocking15:48
comstudyeah, i get that.  that's not what i meant...15:49
comstudtake our control panel for instance...15:49
comstudthe call for build is going to sit there and wait15:49
comstuduntil set_admin_password finds the host15:49
vishyah i see15:49
comstudif for whatever reason that takes 20 seconds...15:49
comstudyea15:50
vishyok so the purpose of the greenthread is so that the call can return immediately15:50
vishymakes sense now15:50
comstudyeah15:50
vishythx15:50
comstudthere's no data being returned that's dependent on that finishing first15:50
comstudi don't necessarily like that there's a 2nd cast to set the password, though.15:51
comstudlong term, i think compute should handle this when it sees a spawn request15:52
*** rnirmal has joined #openstack-dev15:52
vishycomstud: yes, perhaps that should all be moved down into compute.manager15:52
comstudthat would kill this problem overall, and I think just makes more sense15:53
comstudbut anyway, the current fix works for now to get us to 50 builds at once15:54
comstudi need 766404 reviewed again15:54
comstudthat's another important one related to this15:54

dragondmhmm...  Random thought: Shouldn't  openstackjenkins be relaying project build statuses here in -dev instead of #openstack ?16:19

comstudstrange, i had checked that it passed16:42
comstudi'll take a look16:42
comstudor maybe i didn't after i wrote the test16:45

BK_manvishy: hi! any special configuration for network VlanManager while several hosts? Can't ping instances on compute nodes, on CC - it's ok17:03
vishyBK_man: you have to turn on vlan trunking on your switch17:03
vishyfor the vlans you are using17:03
vishyer lets take this back to openstack channel17:04

sorenvishy, comstud: Wazzup?18:25
sorencomstud: How about we take your eventlet patch and stick an updated eventlet in the PPA and see how it goes?18:26
comstudthat'd be cool18:27
lorin1Possibly 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
comstudsoren: did you look it over completely? i think it makes sense.18:27
sorencomstud: Haven't had the surplus brainpower to review it in detail, no.18:28
sorencomstud: The approach seems sound, though.18:29
comstudno worries18:29
comstudbeen exercising it pretty heavily18:29
comstudso i think it's sound18:30
sorenI do wish upstream was more interested :-/18:32
comstudmaybe if i do a real branch and do a pull request it'll get more attention18:47
comstudwhat version is the current ppa based off of?18:48
comstudi guess 0.9.1418:49
comstudthere's a 0.9.15 now18:49
sorenI forget.18:49
sorenYeah, 0.9.14 sounds right.18:49
sorencomstud: There's a good chance I won't get to it until next week18:50
* soren adds to TODO list18:50
comstudno worries18:53
