omar_rally_noobhow do you know exactly what a task is doing for example https://github.com/openstack/rally/blob/master/samples/tasks/scenarios/authenticate/keystone.json I understand the task is going to create 3 tenants with 50 users in each tenant and auth 100 times with 5db transactions at a time.00:43
omar_rally_noobdoes the task produce logs or detailed output, all i get are results from running these tasks00:45

boris-42@stpierre hi17:37
boris-42@stpierre http://logs.openstack.org/33/299833/2/check/gate-rally-dsvm-neutron-rally/c064f03/rally-plot/resources_diff.txt.gz17:37
boris-42stpierre: ^ this looks bad17:37
stpierrei don't think that's a new problem17:40
stpierrelooks like it may have somehow been caused by https://review.openstack.org/#/c/27263817:43
stpierreyep, loads of tracebacks here: http://logs.openstack.org/38/272638/14/check/gate-rally-dsvm-neutron-rally/40927c3/console.html.gz17:45
*** ushkalim has quit IRC17:46
boris-42stpierre: please be very accurate when you are working on such things like cleanup17:46
boris-42it's very easy to mess up everything17:46
stpierrewe need to get the resource checks to influence the success of the job17:47
stpierrethat review was +2'd by four separate cores17:47
stpierreif five of us could overlook the same thing, that's a problem with the gate IMO17:48
-openstackstatus- NOTICE: Job failures for missing traceroute packages are in the process of being fixed now, ETA 30 minutes to effectiveness for new jobs17:49
boris-42stpierre: the problem is that core team started thinking that if it pass gates patch is OK and works for any cases17:50
stpierrewe should strive to make that the case17:50
stpierrepeople are really good at screwing up, and they always will be. if there's an unexpected increase in resources, that should fail the job.17:50
boris-42stpierre: it's imposible, there will be always ways to find how to break it without braking gates17:50
stpierrethat doesn't mean we should just give up17:51
stpierrewe should get as close as we can17:51
boris-42stpierre: so I agree that there is room for improvement for Ci17:51
boris-42stpierre: so the problem here is that WE (as a core team) KNOW that we are NOT testing cleanup very well17:51
stpierrewell, i'm making a concrete suggestion for how to do it17:51
boris-42in gates17:51
stpierreso let's test it better. we've got the data, we just need to make it fail the job17:52
boris-42stpierre: yep we can hardocde the amount of possible failuers17:52
boris-42stpierre: however it won't be ideal17:52
stpierredon't let the perfect be the enemy of the good. it'd be more ideal than it is right now17:52
boris-42can you try to analyze the reason of failuers?17:53
stpierreit's pretty obvious17:54
*** klkumar has quit IRC17:54
stpierreand is hopefully a one-line fix17:54
boris-42stpierre: ok I will wait for patch17:55
boris-42stpierre: btw17:55
boris-42https://github.com/openstack/rally/blob/master/tests/ci/osresources.py#L29817:55
boris-42stpierre: ^17:55
boris-42stpierre: so seems like we should hardcode here len of changes that we are allowing17:56
boris-42stpierre: or even do the better job and just fail if there are any changes17:56
openstackgerritChris St. Pierre proposed openstack/rally: Cleanup: Fix getting name from neutron resources  https://review.openstack.org/30012117:57
stpierrewe need to make it a bit smarter, since there are some resources we expect -- 'default' security groups and the _member_ role at a minimum, it looks like17:58
stpierrebut i think we can probably filter those out, and then check for any additional changes17:58
stpierrethat'd be better than just failing on > 3 changes17:58
stpierrei'll try to get that done this afternoon17:58
boris-42stpierre: thanks18:14

boris-42stpierre: ping19:28
stpierrepong19:28
boris-42stpierre: I talk to kevinbenton19:28
boris-42stpierre: he said that it is known issue that you can't delete security group in neutron19:28
boris-42stpierre: so he will try to fix this on neutron side19:29
stpierreright19:29
stpierresame is true in nova-net19:29
boris-42stpierre: btw you patch works19:29
boris-42stpierre: going to merge it19:29
boris-42stpierre: so he checked he is saying that we need to delete security groups as a admin19:29
boris-42stpierre: so this seems like not a hard to fix stuff19:29
stpierreok19:30
boris-42stpierre: here is the patch https://review.openstack.org/#/c/296402/219:31
stpierreit looks like we set admin_required=True on the base NeutronMixin, but that isn't inherited19:31
boris-42stpierre: however it is not properly written19:31
boris-42stpierre: so actually it's a bit hard to fix bug19:32
boris-42stpierre: because if we are running with existing users and without admin (which will be possible in future) we shouldn't even try to delete default secruity group19:32
boris-42stpierre: seems like some refactoring will be required here19:33
stpierrei dunno, lots of the cleanup resources require admin. it seems reasonable to just set admin_required on NeutronSecurityGroup for now. admittedly it's not perfectly forward-looking, but it should be a one-line fix for an actual bug, and it will be just one of a large list of things that require refactoring later.19:35
stpierrei.e., we don't seem to lose anything by fixing it now19:35
boris-42stpierre: nope it is not19:36
boris-42stpierre: please let not make our life harder and harder19:37
stpierrethat doesn't make it any harder than it already is19:37
boris-42stpierre: each hack that we are adding is making rally less maintable19:37
boris-42stpierre: it makes it harder to make non-admin mode19:37
boris-42stpierre: I have an idea how to fix it19:37
stpierreit fixes a real actual bug in one line, and there are twelve other places that already ahve admin_required19:37
boris-42stpierre: it creates another one19:38
stpierrewe can't just refuse to fix minor, simple bugs any time they conflict with some future idea that isn't even a spec yet19:38
boris-42stpierre: actually it creates 2 bugs19:38
boris-421) if you are using existing users, you will delete default security group of it (which is bad idea)19:39
boris-422) scenarios that don't require actually admin will start requiring it19:39
stpierrethat second one isn't a bug, because if they need to clean up security groups then they do actually require admin19:39
boris-42stpierre: sorry but I am already working 2 years for making non admin19:40
boris-42stpierre: and had to refactor whole Rally to achieve that19:40
boris-42stpierre: even plugin base was related to this task19:40
boris-42stpierre: and creating rally context*19:40
stpierrei've gotta say, the amount of time we're spending spinning our wheels and not merging real fixes to actual bugs, or important features that are desperately needed, because of these distant pipe dream features is starting to get quite frustrating.19:40
boris-42stpierre: and current cleanups are trying to achieve this19:41
boris-42stpierre: so there is way to fix this19:41
boris-42stpierre: btw you don't need to be a admin to cleanup security groups19:41
boris-42stpierre: just for default security group19:41
stpierreright, but if we want to do a complete job of cleanup, that's part of it.19:41
boris-42stpierre: so19:42
boris-42stpierre: there is another way19:42
stpierreok19:42
boris-42stpierre: btw19:42
boris-42stpierre: the code is rally19:43
boris-42stpierre: why this doesn't cleanup default security groups?19:43
boris-42https://github.com/openstack/rally/blob/master/rally/plugins/openstack/context/keystone/users.py#L124-L13919:43
stpierrethat is an excellent question19:44
stpierrei suspect that *is* cleaning up most of them, since we're only seeing a single default security group in the osresources output19:44
stpierreso the question is where that one stray secgroup is coming from19:44
stpierrewhich might have a much simpler answer19:44
boris-42stpierre: so19:47
boris-42stpierre: it's interesting stuff19:48
stpierrelooks like both of the 'default' security groups are for the 'service' tenant19:48
stpierrewhich is created by devstack19:48
stpierreso it should show up in the pre-rally inventory AFAICT19:48
