The review is out. 14:12:34 sdague: yeah, that totally needs doing, I guess no one owned doing the "paper work" for that, let me own that 14:12:38 ctrl + alt + del 14:12:53 so I will talk to mikal and get that un-stuck somehow 14:13:08 #action johnthetubaguy to sort out whats happening with ec2 after last weeks meeing 14:13:15 johnthetubaguy: especially as we are really talking about 1 patch to a v21 microversion (we'll only do this on v21, not on v2) 14:13:22 cool, thanks 14:13:36 johnthetubaguy: thanks 14:13:42 which I also think will give us a good carrot for v21 14:14:03 you'll need that for this enhanced ec2 support 14:14:07 sdague: alevine: I will try get an answer by the end of the week, hopefully you will see the −2 go away quickly 14:14:14 johnthetubaguy: thanks 14:14:15 sdague: yeah, its a nice one 14:14:37 sorry folks, clearly a totally screw up there, miss understood the comments on the patch, I will fix that 14:14:46 #topic python-novaclient release 14:14:49 thanks johnthetubaguy, appreciated 14:14:51 johnthetubaguy: Yes, thanks again. 14:14:54 so I guess this was the topic last week 14:15:07 no idea why thats not happened 14:15:12 anyone want to raise that here? 14:15:31 was this the release pinning stuff? 14:15:39 I think that was all fixed. 14:15:42 we should be safe on release pinning 14:15:48 that was my take too 14:16:01 I think it's good to go, someone that knows how, and has permissions just needs to do it 14:16:05 #action johnthetubaguy to kick mikal over python-novaclient 14:16:17 #topic gate status 14:16:27 and as a part b) we should probably increase the pool of people that know how, and have permissions (which I think was on the thread) 14:16:48 sdague: yeah, agreed, the timezone coverage argument made lots of sense 14:17:04 the nova side seems pretty solid, I've seen a lot of neutron bounce recently 14:17:22 yeah, I don't see anything here, 14:17:24 moving on 14:17:31 #topic bugs 14:17:47 we we were making progress here, but it seems to have slowed 14:17:57 possibly because we did the easy ones, but lets keep pushing 14:18:05 #link https://etherpad.openstack.org/p/kilo-nova-priorities-tracking 14:18:06 johnthetubaguy: agreed, that's also needs more time now 14:18:21 bottom of the above page has lots of links for "active" bug reviews 14:18:40 #help please help review more bugs listed at the bottom of https://etherpad.openstack.org/p/kilo-nova-priorities-tracking 14:19:08 #topic stuck reviews 14:19:10 yeh, I think the # of trivial bug fixes in our review system are actually quite small 14:19:37 This one's still stuck: https://review.openstack.org/#/c/134499/3 14:19:43 sdague: yeah, maybe we merged the fixes, time do some some more fixes 14:19:52 Not terribly important, but stuck 14:20:02 Due to -1 from dansmith 14:20:27 mdbooth: ah, yes, do we have tests to debunk dan't claim about the issue? 14:20:45 johnthetubaguy: Yeah, I wrote one 14:20:58 * anteaya votes for dan't for his new friday nick 14:21:01 I'm not going to commit it, though, because it would just be noise 14:21:24 mdbooth: can you add it after that patch maybe? 14:21:33 It's a comment in the patch 14:21:39 Seriously, it doesn't make any sense 14:21:51 The act of writing the test reveals its nonsensicalness 14:22:13 The confusion appears to be over the behaviour of assignment in python 14:23:12 Jay Lau also posted a test 14:23:13 johnthetubaguy: there are a couple of critical bugs in the vmware driver that have been in review for months. 14:23:37 garyk: can you add the top two or three into the review list in that etherpad? 14:23:40 i fpossible could we please get a few eyes on https://review.openstack.org/113908 and https://review.openstack.org/124782 14:23:50 johnthetubaguy: sure, will do. thanks 14:24:00 mdbooth: yeh, that seems fine after the follow on discussion 14:24:09 garyk: thanks, just keep an eye on it 14:24:30 mdbooth: yeah, it looks OK, one of us, or sdague should approve that one I think 14:24:37 Cool, thanks 14:24:41 cool, any more? 14:24:52 sdague: thank you 14:25:02 did I miss the kilo priorties section of the agenda? 14:25:16 anteaya: whoops I did 14:25:24 #topic priorities 14:25:34 * anteaya has an item 14:25:41 #link https://etherpad.openstack.org/p/kilo-nova-priorities-tracking 14:25:49 updates are available in the usual place 14:25:58 #help please review the priority patches in here: https://etherpad.openstack.org/p/kilo-nova-priorities-tracking 14:26:03 anteaya: fire away 14:26:07 thanks 14:26:19 so at the last nova net to neutron migration meeting 14:26:26 which johnthetubaguy attended, thank you 14:26:40 I heard my name mentioned and came running 14:26:40 I am hearing taht nova would like the direction to be subclassing the api 14:26:48 thanks for that 14:26:51 anteaya: no 14:26:54 which means redirecting to L 14:27:00 no 14:27:05 then I mis-heard 14:27:11 * anteaya listens again 14:27:30 anteaya: there is some concern about doing this by just subclassing objects and replicating at the persistence layer 14:27:36 dansmith: I was missing interpreting the comments on the review I guess, we seemed against the hack nova objects approach at least? 14:28:10 johnthetubaguy: anteaya: he's going to do another round of a more complicated piece of the implementation so that we can see what it looks like at the objects layer 14:28:19 but it feels really awkward to me to do it there 14:28:35 +1 14:28:45 dansmith: is this for the using neutron but a few hosts still nova-net case? 14:28:52 it's definitely a hack that avoids making changes to either nova-net or neutronapi to make this actually a natively supportable thing 14:29:22 johnthetubaguy: this is for making us run using nova-net, but every time we save something, we redirect to neutron under the covers 14:29:33 ...and also try to save stuff into nova-net's database as well 14:29:58 ah, yeah, the sync stage 14:30:05 if we didn't have objects, it would be identical to putting stuff into db_api to keep neutron and nova-net in sync 14:30:19 it's doable, and maybe it's the least ugly thing, but it doesn't feel that way 14:30:31 I also don't have a better suggestion (well I do: don't do this silly thing at all), but... 14:30:32 dansmith: so obondarev talked to you? 14:30:35 right, it feels the wrong level of abstraction 14:30:41 anteaya: yes 14:30:46 wonderful 14:30:49 sorry I missed that 14:30:56 so happy to hear 14:31:10 * anteaya will recheck channel logs 14:31:14 anteaya: sorry, I shouldn't have said no to what you were hearing -- I meant no to the analysis 14:31:21 that is fine 14:31:27 since you had new info 14:31:31 glad he talked to you 14:31:58 so right now you and oleg have agreed that oleg will write a new patch and you will review? 14:32:03 do I have that correct/ 14:32:13 * mriedem joins super late 14:32:21 he's going to expand on it, yes 14:32:28 good enough for me 14:32:30 thanks 14:32:37 but I will say,m 14:32:40 * anteaya will wait for another round then on the patch 14:33:04 that even if we go this route, time is getting pretty tight for me to imagine this is actually going to be a workable thing in kilo timeframe, just given the level at which we're operating here 14:33:13 yes 14:33:17 and I concur with you 14:33:23 but oleg seems determined 14:33:35 and he did talk to you, which is what I was hoping for 14:33:42 so I am willing to give him a shot 14:33:54 if you are 14:34:34 anteaya: so the code has technically missed the deadlines for kilo now, so we can't let it merge without some sort of exception, but lets not bog down on that 14:34:41 right 14:34:45 johnthetubaguy: this is a priority right? 14:34:49 so it has until k3? 14:34:52 since we don't know if we have anything worth excepting 14:35:34 dansmith: yeah, just we don't have a blueprint merged for that yet, but we could do that 14:35:50 I have what I need for this week, sorry to keep others waiting 14:35:53 anyways, thats s pointless debate, if its ready we will do something exceptional for it 14:35:53 thank you 14:35:56 okay, I didn't think that mattered, but I don't know what to put in a blueprint at this point 14:35:57 probably 14:36:20 dansmith: its just tracking I guess, mostly for docs at this point 14:36:29 but thats just paper work we would need to do 14:36:36 anyways, any more on priority stuff? 14:36:46 oh and we have a docs patch: https://review.openstack.org/#/c/155947 14:36:52 if folks could review that 14:37:06 it will be presented at ops mid-cycle 14:37:10 by sdague 14:37:12 anteaya: is that linked in the tracking etherpad? 14:37:16 yes 14:37:31 anteaya: awesome, thanks 14:37:38 #topic open discussion 14:37:49 o/ 14:37:56 mriedem: just a poke about the gate incase you wanted to raise something 14:38:00 alaski: fire away 14:38:08 https://review.openstack.org/#/c/153666/ vs https://review.openstack.org/#/c/157156/ 14:38:13 johnthetubaguy: http://status.openstack.org/elastic-recheck/gate.html 14:38:21 essentially alembic vs sqla-migrate for new migrations 14:39:04 I like alembic personally, but it does mean that devs need to learn a new system 14:39:24 though ultimately this will be moot with the online schema change work 14:39:54 I want to gather thoughts and opinions on which path I should go with 14:40:13 alaski: so its a new DB right? 14:40:29 johnthetubaguy: yes, totally fresh database 14:40:30 and alembic is the one actually maintained by the upstream project still 14:40:40 so thats quite attractive from where I am sat 14:40:56 I think the question is, 14:40:58 and as you said, it all goes away once we have online migrations working I guess 14:41:08 if we're not going to see alembic from our code once we have the online schema bits, 14:41:16 then it's just learning a new thing for no real gain 14:41:19 but thats a new tech for a very short amount of time I guess? 14:41:20 er, yeah, that :) 14:41:20 i suggest reaching out to a few people in neutron who work with the alembic migrations 14:41:30 salv-orlando would be a good place to start 14:41:44 the nova way of writing them is far easier in my opinion 14:42:01 garyk: to ask what? 14:42:15 whether it is a good way to go, what the painpoints are etc. 14:42:24 alaski: you know, this one is quite easy I guess: https://review.openstack.org/#/c/157156/2/nova/db/sqlalchemy/api_migrations/migrate_repo/versions/001_cell_mapping.py,cm 14:42:35 Vaguely on the topic of migrations, I posted this earlier: http://lists.openstack.org/pipermail/openstack-dev/2015-February/057324.html 14:42:38 the migrations are very similar, though alembic can do a lot of it automatically 14:43:02 It's about creating a unique constraint in the db to cover the use case of osapi_compute_unique_server_name_scope 14:43:22 However, it would seem to require configuring the db schema on the fly 14:43:28 it sounds like there's a leaning towards not learning a new system for a short period of time 14:43:49 so I'll move forward with sqla-migrate 14:43:55 as a followup 14:44:09 I moved the current migrations in my patch to a new directory 14:44:16 alaski: honestly, I think that'd be my preference.. avoid putting any more blockers in our way 14:44:20 alaski: I like how it gives us more reasons to drop that code you are adding once we are happy with the online stuff 14:44:24 unless there's some real technical reason 14:44:40 alaski: I was thinking it was good to learn the new way 14:44:52 do people like/dislike the directory move to distinguish migrations? 14:45:00 mdbooth: I would vote we deprecate the config option, FWIW, and see who shouts 14:45:03 dansmith: no real technical reason, beyond alembic autogenerating migrations 14:45:19 alaski: maybe don't rename the old one? 14:45:26 alaski: right, I meant reason like "sqlamigrate is really unable to do two streams" or something 14:45:27 johnthetubaguy: Works for me. 14:45:46 dansmith: yeah, everything seems to work fine at this point 14:46:02 then my vote would be to concentrate on other hard problems I think 14:46:12 even though I think I was +1 on alembic before, 14:46:13 also, openstack project owns migrate at this point, so we can fix it if we need to 14:46:16 alaski: ah, its two different DBs with separate sqlalchemy_migrate streams right? 14:46:21 but wasn't really factoring in the online schema thing 14:46:26 johnthetubaguy: yes 14:46:33 johnthetubaguy: yes, I renamed to distinguish them easily 14:46:40 feel free to ping me to rubberstamp any and all sqla-migrate changes :) 14:46:42 alaski: got it, thats a nice solution 14:47:11 johnthetubaguy: it does break turbo-hipster which hardcodes where it looks for migrations, but I have an email to them already about that 14:47:29 alaski: can we avoid the rename, or does that just look too messy? 14:47:40 it can be avoided for now 14:47:47 I think eventually we'll want it 14:48:09 I think I got what I needed 14:48:18 drop alembic, probably don't rename for now 14:48:22 well, eventually we just delete it, but yeah, that too 14:48:29 cools 14:48:31 but reviews welcome with further feedback 14:49:30 cool 14:49:33 seems like we are done 14:49:39 any last items? 14:49:56 thanks all, feedback on the agenda welcome, we had a few dead areas today 14:50:06 #endmeeting
