WIP patch is up: https://review.openstack.org/113975 17:53:57 s3wong: oh ince 17:54:00 *nice 17:54:11 as it doesn't have DB migration script, it will fail a bunch of CIs and gate tests 17:54:12 s3wong: great 17:54:22 but I will work on that soon(ish) 17:54:47 How on earth did this spec get approved? 17:54:53 for the record, my wip is still at https://review.openstack.org/#/c/108049/ (vpn), but haven't worked on it this week 17:54:55 s3wong: sorry for being pedantic on process, can you add the link to the wiki page: https://wiki.openstack.org/wiki/Neutron/AdvancedServices/JunoPlan 17:54:55 I think it needs further discussion. 17:55:16 it is only API and DB for service interface; so the plugin and even service base work has NOT been done 17:55:22 so a lot of work ahead, still 17:55:30 marios: yeah great, was going to check next? 17:55:38 next? -> next 17:55:50 s3wong: So, why don't we defer to kilo since it's unlikely to be ready in the next 9 days? 17:56:50 marun: I will defer that decision to the rest of the team 17:57:01 SumitNaiksatam: so i actually wanted to bring this up - not sure if we need to defer, but I think we need some clarity (I was kinda hoping on comments to my wip that would perhaps help clarify things for me) 17:57:10 err sorry that wasn't meant just for sumit 17:57:28 marios: yes 17:57:34 so a couple days ago i tried to collect the threads. we've been tlaking about this in the last 3 meetings 17:57:35 if marios , kanzhe, SridharRamaswamy, and SumitNaiksatam are all in agreement with that, I have no objection 17:57:37 so there are two aspects at play here 17:57:56 i looked back over the logs and i'd say at least we need to update the spec to clarify some things 17:58:00 SumitNaiksatam: sorry, go ahead 17:58:04 one is the direction that the project wants to take 17:58:19 hence wanted to check with the PTL right at the outset 17:58:28 we tried to do that at the beginning of the last meeting as well 17:58:47 currently as it stands, the bp spec was approved for J3 17:59:07 the second aspect is about the confidence of the author 17:59:13 in finishing the patch 17:59:40 i believe that the requirement in that the patch should be out of WIP by aug 21st 17:59:56 SumitNaiksatam: there's a third aspect i believe. 18:00:02 marios: sure, please go ahead 18:00:22 SumitNaiksatam: which is what i was trying to say above. the whole 'defer entry' with the messaging isn't described in the spec 18:00:39 (as well as some minor details like the db migration aspecs, keeping certain fields that we said we'd nuke) 18:00:54 marios: ‘defer entry’? 18:01:32 sec, i will copy/paste, apolgoies in advance: 18:01:34 17:50:39 SumitNaiksatam: have we made a decision on how the serviceInterfacePlugin will get the service instance UUID yet? 18:01:37 17:52:57 s3wong: we can maintain a table in the new service insertion plugin, that will hold a reference to the uuids against their service type 18:01:47 (from 2014-07-30-17.31.log.html) 18:02:07 I'm having a hard time understanding why service insertion should be a part of Neutron. 18:02:11 marios: ah, i got a little confused by the ‘defer’ part 18:02:23 yeah, it started off being described that way in the meeting before that 18:02:24 All the discussion around NFV has made it clear that we don't want to focus on orchestration at that level. 18:02:36 We need to support it out-of-band, sure. 18:02:38 But doing it in-tree? 18:03:01 That was agreed on at summit as being a non-starter, at least for now. 18:03:21 marun: what was agreed at the summit as being non-starter? 18:03:26 The fact that none of the spec approvers were in the room at the summit session is pretty telling. 18:03:40 And I think good grounds for revoking approval. 18:03:43 marun: which room? 18:03:49 Neutron room, last session. 18:04:05 SumitNaiksatam: or where you there? 18:04:10 where -> were 18:04:32 marun: no i wasnt there, i had communitcated to the PTL that i had travel plans which could not be changed at the last minute 18:04:39 i think everyone was on planes home for that meeting; i'm not sure that's indicative of anything. 18:04:59 marun: at least i was not aware of any decisions that were made during that meeting that were made public 18:05:06 Regardless of why, I think the validity of the spec is nonetheless in question. 18:05:15 marun: was this conveyed to the mailing list or captured in any etherpad? 18:06:03 SumitNaiksatam: Given that there has been continual rejection of the ideas conveyed in the spec in successive summits, I'm not sure why you would take spec approval as achievement of consensus around the issue. 18:06:10 And I seriously doubt it comes as a surprise to you. 18:06:29 marun: reject of the idea? by who? 18:06:32 SumitNaiksatam: And yes, it was captured in the summit etherpad. 18:06:47 *rejection 18:07:20 SumitNaiksatam: https://etherpad.openstack.org/p/servicevm 18:07:20 marun, though i'm not a spec approver I was present in the last session and don't remember the decision reg service insertion. will take a look at the etherpad 18:07:23 why isnt the spec review process being followed if you are fundamentally in disagreement with the idea? 18:07:46 SumitNaiksatam: I think you are confusing approval of a spec with consensus. 18:08:21 marun: i am not talking about approval or consensus 18:08:39 SumitNaiksatam: I think this time the spec process was not mature for Neutron and we are realizing that. Hopefully, next cycle will be better. 18:08:46 marun: i am just saying, if you had concerns, why werent they expressed on the blueprint spec during the review process 18:09:01 marun: the etherpad you point to is about Service VMs 18:09:24 marun: there was an entire design summit session which was on the topics that we are discussing in this meeting 18:09:38 SumitNaiksatam: I'm not sure about you, but there are more specs than anyone can cover. 18:09:42 marun: we are not discussing service VM related insertion in this meeting 18:09:57 SumitNaiksatam: insertion is the same issue in both casese 18:10:05 marun: hence we have sub teams to scale the problem 18:10:12 or rather solution to the problem 18:10:36 marun: not quite 18:10:40 SumitNaiksatam: The discussion there made it clear that while we need to support the capability to allow unfiltered or trunked ports, that we did not want to be deciding how that plugging took place within neutron. 18:10:45 marun: can you explain why its the same in both cases? 18:10:54 SumitNaiksatam: The subteams are still responsible to the community as whole. 18:11:12 marun: of course 18:11:12 SumitNaiksatam: There is no good excuse for implementing the wrong things. 18:11:27 marun: we are not discussing anything related to trunking in this spec 18:11:27 SumitNaiksatam: If we figure out later in the cycle, it sucks. Ideally we would figure it out as soon as possible. 18:11:55 SumitNaiksatam: I gave those only as examples of things needed to support the service vm use-cases. 18:11:57 marun: apologies if this is a silly question, but have you read the spec in question? it is quite simple in scope, just trying to introduce a single 'context' that captures where a service 'exists' (e.g. the router a vpn service is associated with) in a centralised manner 18:12:02 marun: yes, and hence it was proposed in the design summit session and discussed during the design summit 18:12:21 SumitNaiksatam: But the issue at hand - whether we need to support service insertion in neutron - is the same. 18:12:40 marun: please see marios’ comment, i think you are misunderstanding the spec 18:12:43 SumitNaiksatam: It should be done outside of the tree to prove its worth before we waste time experimenting in the tree. 18:13:21 marun: the team has already iterated once on this idea during the icehouse cycle 18:13:28 marun: this is enhancement of that idea 18:13:42 marun: it _was_ more complex before but was simplified quite a bit in order to land 18:14:00 marun: and in my opinion not a new idea that is in early stage of experimentation 18:15:09 marun: i am still unable to find any where in the etherpad where this bp spec or the service insertion problem that is being attempted to be solved here is being referenced 18:15:17 and serves to provide a common framework for insertion being impl independently by services such as fwaas, vpnaas 18:15:58 marun: besides, this is one blueprint of a big framework 18:16:14 marun: a separate blueprint was registered for defining that framework 18:16:29 marun: that was approved by the PTL as welll among other reviewers 18:16:47 SumitNaiksatam: I like how you always seem to fall back on procedural arguments. 18:16:52 SumitNaiksatam: Rather than technical ones. 18:17:05 marun: this team hasnt gotten any direction that any of that is invalid or misguided effort until your opinion here 18:17:23 marun: what is the technical issue? 18:17:31 SumitNaiksatam: If we are going to go that route, I would point out that all approvers of the spec in question work for the same company. 18:17:47 marun: which spec? 18:17:50 SumitNaiksatam: Which doesn't imply to me that we are getting the core oversight that we would expect. 18:18:03 marun: i am talking about the umbrella spec 18:18:22 #link https://review.openstack.org/#/c/92200 18:18:40 this blueprint was added per feedback from the PTL 18:18:54 that the whole community needs to be aware of the general direction we are taking here 18:19:08 this was also in response to the issues raised in the LBaaS discussion 18:19:13 SumitNaiksatam: this spec: https://review.openstack.org/#/c/93128/22 18:19:33 that the necessary clean interfaces do not exist on the neutron side to achive integration of services 18:19:40 * markmcclain1 reads scrollback 18:20:31 emagana: uff! 18:20:48 s3wong: so what is your comfort level with getting this patch out of WIP? 18:20:59 s3wong: and is Kanzhe back from vacation now? 18:21:23 Ok… so we're 9days out 18:21:34 SumitNaiksatam: I will be working on this and GBP driver full time over this and next week 18:21:45 the majority of the neutron core team has been focused on scaling, stability, and parity 18:21:51 SumitNaiksatam: I see Kanzhe online (via Google chat), but haven't heard from him yet 18:22:27 and it seems that we're unlikely to get this delivered for Juno 18:22:54 markmcclain1: i would like to see a direction from the PTL on this 18:22:59 also I'm not sure that the LBaaS team is even aware that this deprecates part of their API 18:23:05 markmcclain1, could we make that decision 8/21 based on the readiness of the patch 18:23:26 however it seems unfair to make this judgement even before we reach the FFP deadline 18:23:28 SumitNaiksatam: I think your attempts to appeal to a higher power are in vain. 18:23:45 marun: i am not trying to appeal to anyone 18:23:56 SumitNaiksatam: We still don't have parity with Nova. 18:24:12 SumitNaiksatam: why do we have to have mestery weigh in on everything? the feature is still in WIP and no of the discussion here seems to indicate that it will leave that status w/o heroic effort before Tuesday 18:24:46 markmcclain1: hence checking with the author of the patch himself 18:25:09 markmcclain1: if he/they dont feel confident, then there is nothing to be argued or for against 18:25:23 SumitNaiksatam: markmcclain1: so I am still committed to get it ready before next Thursday 18:25:24 markmcclain1: it is always the case more work gets done closer to the milestone 18:25:47 that said i dont have any interest in wasting anyone’s time here 18:25:51 I totally understand that work gets done close to deadline 18:26:14 hence we sought clarification last week as well, whether this is going to get blocked by a -2 down the line 18:26:22 but posting something that deprecates another team's api so close to milestone-3 is asking for trouble 18:26:26 but if the cores consensus is this won't land anyway, please let us know now 18:26:26 if that plan is already in place, then its not work pursuing this effort 18:26:57 markmcclain1: i am not sure i understand the part of about deprecate another team’s api 18:27:12 markmcclain1: this is certainly new information to me or the team here 18:27:26 markmcclain1: which team’s API does this deprecate? 18:27:50 https://review.openstack.org/#/c/93128/22 18:28:05 line 318 18:28:56 also the lbaas team has been iterating all summer on new drivers that take none of thing into account 18:28:56 markmcclain1: ok 18:29:23 there is clearly duplicative and confusing work occurring because of the two silos 18:29:27 markmcclain1: my understanding was that the lbaas team is represented here, and also this team is represented on the lbaas side 18:29:36 i believe dougwig is part of the lbaas representation here 18:29:47 and s3wong was part of the representation of this team on the lbaas side 18:29:58 markmcclain1: SumitNaiksatam: to markmcclain1's point, the changes for the services aren't actually going to happen (I mean for ex we already agreed that for vpn, we won't be nuking the router attribute as was stated in the spec) 18:30:07 i dont think any issues have been brought up in this forum about this deprecation statement 18:30:16 sorry, i only attend sporadically, and have really only been paying attention to flavors. i can add some time, but i'm not currently up to speed. 18:30:34 obviously cramming this in a the last moment is a bad idea 18:30:50 SumitNaiksatam: markmcclain1: right, and I did go to the LBaaS mid-cycle and had discussions with blogan and susanne on this 18:31:05 I don't want folks expending superhuman effort for something we have reconciled ahead of time 18:31:15 s/have/have not/ 18:31:21 markmcclain1: again, if you have already decided to -2 this, then there is not point in pursuing further, however please do not mischaracterize this as being crammed at the last minute 18:31:37 not -> no 18:31:40 s3wong: to my knowledge none of the planned v2 specs reference this 18:31:57 SumitNaiksatam: I haven't decided to -2 this because the code is WIP 18:32:27 which is why I'm asking the hard question of whether we can resolve these issues in time 18:32:29 markmcclain1: but i think we do get the hint here 18:32:41 markmcclain1: correct, due to their code being ready by J-2 (earlier schedule) while ours is at J-3 18:32:52 I'd hate for devs to kill themselves implementing for use in the review period to realize we have a bunch of ill fitting parts 18:32:53 markmcclain1, s3wong: correct, v2 hasn't taken this into account yet. i think we likely did talk about it, but it didn't make it to any code. 18:33:17 dougwig: markmcclain1 its also a chicken and egg problem 18:33:21 we went down this road before with provider networks and l3 routers 18:33:22 dougwig: correct 18:33:43 delivering two incompatible features took 2+ cycles to clean up 18:34:11 ok just a time check, we have run out of time for this meeting 18:34:32 can we take an action item to check between s3wong dougwig markmcclain1 if this breaks anything on lbaas? 18:34:40 I would love to see devs helping on the priority staff.. nova parity, migration, even docs! 18:34:41 and decide whether to proceed or not? 18:35:01 SumitNaiksatam: yes, i'd be happy to discuss with s3wong (or anyone else) offline. 18:35:09 SumitNaiksatam: sure 18:35:15 dougwig: great 18:35:28 markmcclain1: sound okay 18:35:29 ? 18:35:33 Please, use the neutron channel for those "offline" discussions 18:35:51 i'd prefer to use #openstack-lbaas, as it's less noisy. 18:35:57 and also logged. 18:36:04 #topic Open Discussion 18:36:16 sorry we could not bring up any of the other agenda items 18:36:17 yeah just really want to make sure we're all on same page and wasting resources 18:36:23 dougwig: I have so many channels open that I can't keep up 18:36:24 markmcclain1: absolutely 18:36:25 *not wasting resources* 18:36:45 any parting thoughts anyone? 18:37:13 s3wong: do you have time in about an hour? 18:37:13 thanks all for joining 18:37:19 #endmeeting
