thrashd0ugal: so.. looked at this again: https://bugs.launchpad.net/tripleo/+bug/1644803 very strange. I think the workflow and the rest of the logic is correct. This looks more like a mistral bug to me.12:04
openstackLaunchpad bug 1644803 in tripleo "openstack overcloud node import fails badly if no glance images are registered yet" [Medium,Triaged] - Assigned to Brad P. Crochet (brad-9)12:04
thrashd0ugal: I bounced rabbitmq and mistral, ran it, and it worked. I got the expected error message back.12:05
*** chlong has quit IRC12:05
thrashd0ugal: But then I ran it again, and got the hang again.12:05
thrashd0ugal: I will continue to look at it. It's odd to say the least.12:06
d0ugalthrash: interesting.12:24
d0ugalthrash: I did report it a while ago, so maybe things have changed.12:24
d0ugalthrash: is the error the same?12:24
thrashd0ugal: well... It worked. Once.12:24
d0ugal:)12:24
thrashd0ugal: but the other times, the client just hangs there waiting.12:25
*** dprince has joined #openstack-mistral12:26
d0ugalthrash: hangling clients usually means nothing has been sent to zaqar12:26
thrashd0ugal: yeah... I can certainly see Mistral sending it, but there's a bunch of timeout messages in the logs...12:27
thrashd0ugal: I'm rebuilding to try again. I'll get some more specific message when/if I see it again.12:27
d0ugalthrash: right, zaqar does seem to fall over quite often - that does concern me.12:28
thrashd0ugal: I haven't seen this happen on other commands... Why just this one?12:28
d0ugalthrash: Not sure, I've seen zaqar problems in other actions.12:30
d0ugals/actions/workflows/12:30
thrashd0ugal: yeah... strange.12:31
d0ugalthrash: but the problem you are describing doesn't really match the error I added to the bug :)12:31
d0ugalWhich seems like a fairly simple value error12:31
thrashd0ugal: you are right... Your report stated it stayed in a RUNNING state. That's clearly not happening to me.12:31
thrashIt's going to ERROR as it should12:32
thrashd0ugal: Nothing is left RUNNING12:32
d0ugalthrash: that might have been because this change hadn't landed: https://github.com/openstack/tripleo-common/commit/0aee2ceb3ca2b26e5271f357b68deca912668f8912:33
d0ugalReturning exceptions objects causes Mistral (it might be fixed now in Mistral too) to fall over12:33
thrashd0ugal: Hmm... That should be there.12:34
thrashI will check that its there when it's done building12:34
thrashd0ugal: Oh. I see what you were saying.12:35
thrashd0ugal: So, your initial bug is probably no longer valid. But I may have another lol12:35

d0ugalthrash: No idea why, it seems to have started fairly recently13:43
*** jaosorior has joined #openstack-mistral13:43
d0ugalI looked into it briefly but wasn't really sure what to do13:43
thrashd0ugal: perhaps new version of oslo messaging from global reqs?13:44
d0ugalthrash: Yeah, sounds likely.13:44
thrashd0ugal: oslo.log was updated in latest13:44
thrashd0ugal: aha... https://github.com/openstack/mistral/commit/4e5cb24c2f75afb07b533739e38f25a18ff0de1c13:45
thrashso there was an update.13:45

tuan__Hi guys14:55
tuan__hope someone still out there14:55
tuan__i just think about the use case of running a long wf14:56
tuan__and then the token is expired14:56
tuan__and how does user re-run that wf if it fails since token is expire14:56
*** bobh has quit IRC14:56
tuan__do we need to implement the mechanism to refresh token14:57

d0ugaltuan__: yes, we do :)15:09
d0ugaltuan__: I think there is a bug for it somewhere15:09
d0ugaltuan__: at the moment, we (tripleo) just make sure out workflows are shorter than 4 hours15:10
tuan__perfect15:10
d0ugalbut it is something I want to improve later15:10
tuan__yeah, actually i have created a snippet for this refreshing15:10
d0ugaloh cool15:10
tuan__well, so i will create a new bug report for it in mistral15:11
*** bobh has quit IRC15:11
d0ugaltuan__: https://bugs.launchpad.net/mistral/+bug/159508415:11
openstackLaunchpad bug 1595084 in Mistral "Workflow execution lifespan is limited by auth token expire time" [High,Confirmed]15:11
tuan__okay i got it15:13
thervetuan__, FWIW that is a "solved" problem in heat, you can find inspiration there15:13
d0ugalyup, I think shardy explained how heat does it in a comment on that bug.15:13

openstackLaunchpad bug 1595084 in Mistral "Workflow execution lifespan is limited by auth token expire time" [High,Confirmed]15:14
tuan__oh, i have checked that15:15
tuan__it seems like if we follow it15:16
tuan__we probably have to change in every component which mistral triggers15:16
tuan__what about we just refresh the token from client side15:16
tuan__not from server side as heat does15:17
