d0ugalI plan on continuing with some Mistral bug triage today!15:05
d0ugalUnless anyone has anything to discuss.15:05
d0ugalbobh: Do you have anything?15:05
bobhtwo quick things:15:06
bobhworkflow failures don't trigger error leg processing (exception caught in task_handler force fails the workflow) and I'm wondering if there is a way to trigger the error legs15:07
d0ugalbobh: Do you have an example? is there a bug?15:07
bobhI think it's actually the root cause of several existing bugs15:08
openstackgerritDoug Hellmann proposed openstack/python-mistralclient master: add lower-constraints job  https://review.openstack.org/55614715:09
bobhAny YAQL/Jinja or sub-workflow error that triggers an exception will not propagate the error handling up to higher-level workflows15:11
d0ugalbobh: right15:13
bobhso the calling workflow is left in RUNNING state when the lower level workflow goes to ERROR15:13
d0ugalInteresting, I had not hit that problem15:13
d0ugalWe should fix it :)15:14
bobh:-)15:14
d0ugalbobh: Is this something you want to work on?15:14
d0ugalbobh: do we have a bug for it?15:14
bobhI need it so I'm happy to work on it15:15
d0ugalbobh: sounds good, let me know if I can help15:16
bobhok - I'll open a bug - or see if there is an existing bug I can reuse15:16
d0ugalbobh: https://bugs.launchpad.net/mistral/+bug/175635315:17
openstackLaunchpad bug 1756353 in Mistral "Mistral workflow stuck in RUNNING state after error "list index of range" encountered" [Medium,Triaged]15:17
d0ugalMaybe that is similar, but if it is my comment on it is wrong :)15:17
d0ugalI think that is different actually15:17
d0ugalbobh: I can't find a bug, so I guess it is best to open one15:21
d0ugalbobh: what was the other thing you had?15:21
bobhd0ugal: ok15:21
bobhd0ugal: wondering if a null input passed to a workflow that has a default value for the input should be overriding the default15:22
bobhd0ugal: if I don't pass the input the default is used15:22
d0ugalbobh: what if I wanted to pass in null and have null be used? :)15:22
bobhd0ugal: yeah that's the problem :-)15:23
d0ugalbobh: I think that would be confusing.15:23
d0ugalWhy do you want it to use the default when you pass null?15:23
*** mcdoker181818 has joined #openstack-mistral15:23
bobhd0ugal: I wanted the parameter to be optional at the top level workflow but the lower level workflow requires it and so has a default15:23
d0ugalbobh: right, I see the problem15:24
d0ugalyou would need to have two tasks in the top-level workflow, one that passes the input and one that doesn't15:24
d0ugalhmm15:24
bobhd0ugal: I'm using dynamic workflow names so I have to build the dict to send in the parameters, so I could use Jinja to update the dict with the parameter if it is non-null otherwise leave it out so it picks up the default15:26
bobhd0ugal: it's just a lot of effort, but it might be the only way since null could be valid as you say15:26
d0ugalbobh: I think it would be a tricky problem to solve15:27
bobhd0ugal: on the first issue, do you think it would be reasonable to check to see if the workflow being force-failed is a subworkflow, and if it is trigger the task error processing in the parent workflow?15:28
bobhd0ugal: yes, and probably not worth the risk of breakage15:28
d0ugalbobh: I think that makes sense, yes15:28
d0ugalbobh: if the sub-workflow fails then the task that started that workflow should error.15:28
bobhd0ugal: that's what I thought - I'll test it on master, I think the environment where we saw the issue is on stable/pike, so it might have been fixed in queens15:30
mcdoker181818Hi all. How can i receive all notification about activity in https://review.openstack.org/#/q/project:openstack/mistral (new MR, changes of MR, merged MR, etc) ?15:30
d0ugalbobh: for the null problem - I guess the sub-workflow could have a task to check if the input is null, and if it is, use the default - does mean you would need to duplicate it...15:30
bobhmcdoker181818: go to Settings -> Watched Projects and add mistral to the list of watched projects15:31
d0ugalmcdoker181818: you can turn it on in the gerrit settings15:31
d0ugal^ what bobh said :)15:31
d0ugalIt can be very noisy!15:31
bobhd0ugal: thanks - I'll figure out a workaround15:31
bobhnoisy but interesting - always seems to be someone working on something15:32
d0ugalTrue.15:33
mcdoker181818Thank you all15:33
bobhd0ugal: thanks - I'll see if I can reproduce the issue on master and open a bug15:34
d0ugalbobh: thanks15:35
hardikjasanibobh, d0ugal: I guess this is the bug bobh is talking about: https://bugs.launchpad.net/mistral/+bug/174364915:49

d0ugaloh, nice15:50
