ricolinwe got one gate fail15:04
ricolinand got 14 days before feature release15:05
ricolinmost of our new resource bp already landed15:05
ricolinstill got the stack define, get resource reality, so do hope we can try to make some of them landing in next week15:07

*** openstack changes topic to "propose for online video meeting next week (Meeting topic: heat)"15:08
ricolinso as we discussed last week15:08
ricolinI would like to propose we host a online video meeting next week15:08
ricolinWe can consider two options zoom or google hangout15:09
zanebricolin: what is the topic for this meeting?15:09
ricolinzaneb, right! "review">15:10
ricolinhow about review?15:10
zanebok, that's a good reason to have a video meeting :)15:10
*** zhipeng has quit IRC15:10
ricolinwe should choose one host and few patches for it15:10
ramishraguys, sorry I've to drop off now, will check the log tomorrow, if there is any action item for me;)15:11
zanebzoom seems like it's worth a try15:12
ricolinramishra, thx will do:)15:12
ricolinzaneb, yep, since hangout might not be the best option for our friend in china and zaneb15:12
ricolinany third suggestion?:)15:12
*** therve has joined #openstack-meeting-515:13
ricolinzoom it is:)15:14
ricolin#action please all prepare for a zoom account for review meeting next week15:14
ricolinI can get a zoom's room which can contain 50 people15:15
LanceHaigI already have a zoom acc :-)15:16
ricolinalso for topic, I would like to propose we review BPs first since feature freeze is near15:16
ricolinLanceHaig, nice!:)15:17
zanebricolin: I can find you some patches to review ;)15:18
*** yamahata has joined #openstack-meeting-515:18
ricolinzaneb, nice15:18
ricolinhere's some bp patches that we should consider to review15:19

ricolin#link https://review.openstack.org/#/q/status:open+project:openstack/heat+branch:master+topic:bp/support-trunk-port15:19
ricolin#link https://review.openstack.org/#/q/status:open+project:openstack/heat+branch:master+topic:bp/get-reality-for-resources15:20
zanebthe stack-definition list is fairly incomplete. I have a lot more patches than that15:20
ricolinzaneb, I know:)15:20
zanebbasically all but the last 5 in https://review.openstack.org/#/q/owner:zbitter%2540redhat.com+status:open15:21
ricolinalso I would like to propose the delay resource one so we left just few for BPs15:21
zanebgood news though, all but one are pretty small15:22
zaneband the one big one is not as bad as it sounds15:22
ricolinzaneb, lol15:23
ricolinalso15:23
ricolinzaneb, I think you should be the host of that meeting:)15:23
zanebricolin: I can talk through my patches. for the others I suggest we try to get the authors of those to talk through them15:24
ricolinzaneb, sure15:25
ricolinwe will do BPs, so might be some BP authors not there15:26
ricolinbut anyway15:26
ricolinwe will see:)15:26
ricolinhope we do it right and keep that from time to time and to PTG15:26

*** openstack changes topic to "Report about rolling upgrade and discuss about multinode gate./ (Meeting topic: heat)"15:27
kiennthi everyone, me again :)15:28
ricolinkiennt, Hi:)15:28
kienntLast week, I focused on finish testing Rolling upgrade and investigate about multinode gate job as you asked me to do .15:28
kienntAbout testing, I have recorded a video, if you have time :)15:28
kiennt#link https://www.youtube.com/watch?v=yboTuNeaLbI15:28
kienntAbout multinode gate job, i have some troubles and ideas that was mentioned in new patch set:15:28
*** ramishra has quit IRC15:28
kiennt#link https://review.openstack.org/#/c/40798915:28
kienntToday i want to ask some questions:15:29
kiennt1. . What kind of multinode job do you want for rolling upgrade testing? Modified Multinode Grenade or Kolla-Ansible gate based on?15:29
kiennt2. Is this gate for Heat only or may be new project like Grenade, but rolling upgrade testing. Because at the moment, no project has mulinode gate job for rolling upgrade testing.15:29
kienntThat's all, what's your opinion? Thank all :)15:30
ricolinfor 1, I think  some grenade-based testing yes15:31
ricolinand for 215:31
ricolinI already ask TC about it15:31
ricolin"Full stack integration testing with services arranged in a mid-upgrade manner is performed on every proposed commit to validate that mixed-version services work together properly. This testing must be performed on configurations that the project considers to be its reference implementations. The arrangement(s) tested will depend on the project (i.e. should be representative of a meaningful-to-operators15:32
ricolinrolling upgrade scenario) and available testing resources. At least one representative arrangement must be tested full-stack in the gate."15:32
ricolinso appears we have to find a way to test that in gate15:32
kienntActually, Rabi  gave me some comments in spec patch set, but he just drops off. Multinode gate, he wants to setup a Kolla gate based on.15:33
kienntGrenade has some limits, it shuts down all services at once, then bring them back (cold-upgrade)15:33
kienntIn rolling upgrade, we need to change the workflow15:34
kienntso it won't shut down all15:34
kiennt    services at once.15:34
ricolinkiennt, I'm fine with both actually, and I think rabi knows better than me on that topic:)15:34
kienntricolin: yes, too bad he just drop off :(15:35
ricolinWhat ever is the pick, we should talk with QA team before we do it15:35
kienntricolin: yes, i agree15:35
zanebdo we know how other projects with this tag do it?15:36
zaneb(maybe there's a magic flag in grenade or something?)15:36
kienntzaneb: i find ironic team want to do this15:36
kiennt#link https://github.com/openstack/ironic-specs/blob/master/specs/approved/support-rolling-upgrade.rst15:37
kiennti found this, multinode gate job was mentioned15:37
zanebit seems to me that the best test would be to run both old and new versions of both heat-api and heat-engine simultaneously, and then throw the entire integration test suite at it15:38
*** dixiaoli has joined #openstack-meeting-515:39
thervezaneb, Is that a supported scenario?15:39
therveI thought we need all the engines updated15:39
therveneeded15:39
zanebtherve: isn't supporting that scenario the point of rolling upgrades?15:40
thervezaneb, No, we can support rolling all engines, and *then* rolling all apis15:40
therveThough I guess with the vhost stuff maybe that works?15:41
zanebtherve: in practice, I don't think anybody does deployments like that15:41
kienntzaneb: i think the best test would be do rolling upgrade (start with old version ,upgrade to new). During this process, throw test at it.15:42
therveOur test suite is not reliable enough to do that15:42
kiennti do rolling upgrade with vhost approach :) i think it's good enough :015:42
zanebkiennt: running old and new versions simultaneously is equivalent to pausing a rolling upgrade in the middle - which is the part we actually want to test15:43
*** dixiaoli has quit IRC15:44
kienntzaneb: okay, i get it. In my test, i did the same thing, 2 heat-api 2 heat-engine. So during rolling, both old and new version  are running simultaneously15:45
zanebcool, yeah that's exactly what I meant15:46
ricolinkiennt, yep, and if we can run entire heat gate test suite during. that's what zaneb wanted15:47
zanebso we just need to find some test framework, preferably maintained by $somebody_else, that makes that easy :)15:47
kienntricolin, zaneb: yep, that's what i wanted too. But the implementation isn't easy.15:48
ricolinkiennt, maybe you should talk to some guys from QA team and make sure what exactly they want15:49
ricolinkiennt, this might make it easier for you15:50
ricolinkiennt, thx for your hard work on this:)15:51
ricolinkiennt, any other thing to raise on this?:)15:52
kienntricolin: yes, thank you. I found a patch set about this, but it was abandoned and i don't know why:15:52
kiennt#link https://review.openstack.org/#/c/433216/3/specs/grenade/rolling_upgrade.rst15:52
kienntsame idea15:52
kiennthow can I contact with rabi? To ask his opinion?.15:53
ricolinhe's always on irc:)15:53
