14:34:31 tbachman: yes 14:34:52 #link https://lists.opendaylight.org/pipermail/discuss/2015-March/004876.html the start of the thread 14:35:00 * regXboi isn't sure what it has mutated into now 14:35:00 regXboi: I haven’t followed it since last night 14:35:38 #info abhijitkumbhare for OF plugin 14:35:49 #info colindixon wants to talk a bit about docs 14:35:53 colindixon: my reason for asking is that if we suddenly start changing what things like mac and ipv6 are stored as, I shudder to think what will happen 14:36:04 * tbachman nods 14:36:09 #info Prem for VPNService 14:36:09 #info +1 to a docs discussion 14:36:28 #info Thanh releng 14:36:58 #topic topics of general concern 14:37:01 regXboi: I got 4 emails in and I started hitting the roof and causing cubes to blowover my beanie-propeller was spinning so hard 14:37:20 colindixon: yes 14:37:50 colindixon: tbachman has found an issue that is with OFP and/or OFJ, he is filing a bug 14:38:04 http://pastebin.com/Mkag1pRn 14:38:06 #link https://lists.opendaylight.org/pipermail/discuss/2015-March/004876.html migrating to storing addresses in a canonical format 14:38:13 regXboi: want to take that away for 2-3 minutes 14:38:17 alagalah: you’re next 14:38:34 colindixon: Ok but if OFP/OFJ is hosed, that means a shed-load of people are blocked 14:38:35 colindixon: I think I can +1 the idea of storing items in IETF canonical format 14:38:44 regXboi: I can too 14:39:05 colindixon: where I get concerned is that it appears to be migrating away from "be conservative in what you send, liberal in what you accept" 14:39:41 in other words, I believe that something in the chain should be assuming that what has been received *isn't* necessarily canonical format and making the conversion 14:39:55 I question whether that should be at the md-sal/yang model 14:40:21 #info the basic issues is that the way we currently store most addresses allows for strings that are logically equal (de:ad::be:ef vs. DE:AD::BE:EF) but are not actually equal which can lead to bugs or at the very least lots of having to do canonicaliztion in every place we uses stuff 14:40:27 * tbachman is filing at least two, possibly 3 bugs 14:40:35 I sorta think that would be one of the jobs of the code that receives the value in question 14:40:39 regXboi: does that cover it? 14:40:43 can you #info other things? 14:40:48 sure 14:40:59 alagalah tbachman - please send us the bugs info 14:41:06 abhijitkumbhare: will do! 14:41:08 abhijitkumbhare: They are coming in 14:41:14 sure 14:41:15 #info regXboi is concerned that the conversation has migrated away from the principal of "be conservative in what you send, liberal in what you accept" 14:41:39 #info regXboi is further concerned that the conversion may be shoehorned into the md-sal/yang model 14:42:24 #info regXboi thinks that the best place for such conversion is the code that acts as the ODL entry point for the value in the first place 14:42:33 colindixon: there you go 14:42:35 regXboi: thanks! 14:42:52 alagalah, tbachman: can you summarize what’s going on? 14:43:03 Pastebin linked above and 14:43:04 * tbachman is in the process of filing said bugs 14:43:18 one is an exception in FRM, resulting in no flows installed 14:43:19 #info alagalah and tbachman say they are openeing bugs with openflow{java,plugin} 14:43:22 We see flows in CONF and we only see table0 correctly in OPER, and tables1-3 have drop flow 14:43:27 #link http://pastebin.com/Mkag1pRn 14:43:35 colindixon: I have OVSDB a heads up ... 14:43:43 regXboi - yeah should be normalized on edges where value is parsed and constructed 14:43:43 another is that table 0 has all our flows, but tables 1, 2, and 3 only get the drop flow 14:43:52 colindixon: and also asked if they had a sandbox and cycles if they could sanity check with building with -U 14:43:59 there’s one other failure case/exception I’ve seen, but haven’t hit again 14:44:03 tbachman: Yep highlighed that... 14:44:07 abhijitkumbhare: do you know what’s going on? 14:44:13 or can you look into it? 14:44:16 ttkacik: (smile) 14:44:22 regXBoi: but that should be done systemically - which requires proper design for that 14:44:45 no - something must have got broken 14:45:08 regXBoi: and I do not believe in Lithium timeframe any fix for this will not be "hack" 14:45:26 #action abhijitkumbhare to follow up with the bugs that gbp is finding in ofj/ofp 14:45:31 tbachman: you’re filing bugs? 14:45:39 ttkacik: I'd argue file bugs against everything that doesn't canonicalize values... 14:45:44 in both cases, flows are in config, but not oper (i.e. oper reflects state of vSwitches) 14:45:46 colindixon: ack 14:45:50 tbachman: and can you get abhijitkumbhare to figure it out? 14:46:04 * tbachman can only type so fast ;) 14:46:06 colindixon: Heads up I ping rovarga_ too, rovarga_ you following this ? 14:46:21 colindixon: Yes tbachman is focusing on the bugs, I'm raising awareness and seeing if others have issues 14:46:26 alagalah: follow what? :) 14:46:41 colindixon: I'll coordinate with shague flaviof to see if they are seeing it to, and tie them to same bug 14:46:53 rovarga_: :) 14:47:22 regXboi: actually fixing that in restconf would result in hack 14:47:24 colindixon: I have a cross product notification topic ... 14:47:25 alagalah and rovarga_ did you sync to cover what you need to? 14:47:35 ttkacik: no, I don't want to fix it in restconf 14:47:39 regXboi: you’re next? 14:47:44 colindixon: no, but I just pinged him so just ensuring I am closing the loop in case he was running things down on his end 14:47:45 that's what I *don't* want to do 14:47:46 alagalah: first thing I got from oflibMichal was: do you have nicira extensions configured? :-) 14:47:47 regXboi: you’re next 14:47:50 colindixon: Cos I forgot about this meeting :D 14:47:51 colindixon: ack 14:48:03 rovarga_: oflibMichal Well... yeah 14:48:04 regXboi: so you are talking mostly about internal apps which explicitly construct these types? 14:48:06 alagalah: (re: your pastebin) 14:48:07 bug #1 https://bugs.opendaylight.org/show_bug.cgi?id=2895 14:48:11 abhijitkumbhare: ^^^ 14:48:25 rovarga_: oflibMichal ^^^^^^ 14:48:30 ttkacik: I'll explain after I'm done with this other topic 14:48:41 regXboi: go for it 14:48:46 colindixon: Ok, so should we take this of ofplugin for now and clear the floor for topics? 14:49:06 colindixon: we got awareness, thats all... tbachman abhijitkumbhare oflibMichal See you on -ofplugin :) 14:49:10 #info the initial yang model for neutron in https://git.opendaylight.org/gerrit/#/c/15989/ has been merged 14:49:16 yes - alagalah sounds good 14:49:33 #info there are edits to it in queue as we adjust it to the openstack data models 14:49:42 but its there for folks to look at and get ready for 14:49:46 #link https://git.opendaylight.org/gerrit/#/c/15989/ link to the patch that will show up in the minutes 14:49:54 #info but it is there for folks to look at and get ready for 14:50:06 colindixon: that's it 14:50:14 thanks! 14:50:39 any other topics? 14:50:51 ttkacik: what I'm saying is that where instances of the particular type is constructed, it should be constructed in canonical form 14:51:28 ttkacik: if the instance is received in a message from an external source (e.g. from openstack for example), the receiving module should canonicalize the instance 14:51:45 bug #2: https://bugs.opendaylight.org/show_bug.cgi?id=2896 14:51:46 #info regXboi and ttkacik have more conversations on the DE:AD::BE:EF in the backgrond (see the full logs) 14:51:49 abhijitkumbhare: ^^^ 14:52:08 ttkacik: I can say that I have tasks for NN to do that with incoming ipv6 and MAC addresses 14:52:11 regXboi: silently? 14:52:24 #info as part of M3 (which all projects have passed) is to provide an outline for their documentation 14:52:43 rovarga_: yes... silently - that's the whole point of the "be conservative in what you send and liberal in what you accept" credo 14:52:47 #info as of last night only 12 of the 44 projects had actually submitted a patch to the docs repo 14:53:18 #link https://lists.opendaylight.org/pipermail/documentation/2015-March/000401.html for a full report with links to patches as of last night 14:53:19 colindixon: I saw your reviews - will see what can be done when resources have time 14:53:24 regXboi: the reason I am asking is that historically, especially for restconf, people have been adamant about being able to interpret interactions as if they were plain strings 14:53:51 rovarga_: I fail to see how I'm saying something other than that 14:54:21 regXboi: well.. for restconf that means that we end up putting a resource somewhere else, because if ipv4 address is in the key, normalization will force it to be a different thing 14:54:22 #info colindixon points out that means that more than 2/3 of projects are techincally not past their M3 deliverables 14:54:31 regXboi: s/ipv4/ipv6/ 14:54:37 #action ALL PROJECTS please make sure you’ve submitted your docs patches 14:54:51 colindixon: What patches are expected? 14:54:52 #info colindixon has also made sure all project docs patches have been reviewed or merged as of last night 14:54:58 Should a lightweight peer review be planned for documentation? Atleast this would ensure the documentation is effective for end users/customers 14:55:18 #link https://wiki.opendaylight.org/view/CrossProject:Documentation_Group:Lithium_Project_Documentation_Requirements#Step-by-step_Guide the step-by-step guide to complete documentation and submit a patch 14:55:22 hideyuki: ^^^^^^ 14:55:27 rovarga_: understood, but I would argue that using something other than canonical ipv6 format is just asking for trouble 14:55:32 Prem: we’re doing that 14:55:37 as part of reviewing the patch 14:55:51 colindixon: ok. Thanks! 14:56:00 any more topics 14:56:01 regXboi: I know, I agree with you, but this is drawing a line, so let's be clear about it 14:56:03 colindixon: I'll check it. I didn't notice this. 14:56:12 rovarga_: yep - I'm drawing a line 14:56:18 regXboi: I would go with postel-was-wrong and reject non-canonical queries 14:56:25 rovarga_: actually, I'm drawing several lines 14:56:36 * tbachman worries that regXboi will go postel ;) 14:56:46 * rovarga_ lol 14:57:04 rovarga_: my problem with rejecting non-canonical queries is that violates the principal of least surprise 14:57:14 * regXboi IS actually going postel 14:57:22 * regXboi but not postal 14:57:42 new topics 14:57:43 going once 14:57:51 colindixon: ah... netty upgrade 14:57:51 anyone? 14:58:05 #info rovarga_ wants to talk aobut Netty upgrades 14:58:06 rovarga_: although, if RESTconf supports 3xx redirects, then the problem can be made moot 14:58:08 rovarga_: the floor is yours 14:58:12 we got an upgrade of netty overnight (4.0.24->4.0.26) 14:58:22 #info we got an upgrade of netty overnight (4.0.24->4.0.26) 14:58:31 #info requested by USC 14:58:44 #info we have weird breakage in bgpcep as a consequence 14:59:07 #info still diagnosing and trying to figure out WT?, but we may end up needing a revert 14:59:08 rovarga_: only bgpcep? 14:59:29 regXboi: bgpcep I know of immediately, am quite busy, so cannot check others 14:59:40 rovarga_: thx 14:59:54 regXboi: and I could replicate it locally, but can no longer do so 14:59:57 rovarga_: thanks 15:00:02 #info while rovarga_ knows of breakage in bgpcep first hand, other projects should check 15:00:12 regXboi: so, this is just a heads up, we obviously would like to not go back 15:00:13 colindixon: that may need to be made an action 15:01:12 #info it may be related to jenkins, but we are not sure yet 15:01:39 so the question is, does USC really need the upgrade? 15:01:51 do we have somebody from USC here? 15:02:12 it appears not 15:02:51 #action rovarga_ to try to fix whatever bug the netty upgrade causes, and if that’s too complictaed talk to USC about why they need the upgrade and think about reverting the upgrade 15:03:16 #info colindixon notes that it should not be somethign unliaterally decided (either by USC or by BGP PCEP) 15:03:30 other topics? 15:03:46 colindixon: that last note should probably get escalated up 15:03:58 because we've had this happen a couple of times now (I think) 15:04:20 #info you mean version management in generaal? 15:04:41 info? 15:04:48 #undo 15:04:48 Removing item from minutes: 15:05:19 #action colindixon to work with the TSC to consider recommending how to change versions in odlparent. maybe require a reviewer from every project that currently uses the dependency to avoid breakages. 15:05:22 other topics 15:05:23 so third party deps are now implicitly under control of odlparent 15:05:49 colindixon: from every project is denagerous -- note how many stalls we have right now 15:06:13 rovarga_: note “maybe” :-) 15:06:42 ok 15:06:44 other topics? 15:06:44 colindixon: I know, but am still cautious 15:06:46 :-) 15:07:19 ah ... 15:07:30 we are finalizing BUG-2399 (automatic containers) 15:07:47 should be ready to land this week 15:08:08 #info yangtools is finalizing BUG-2399 (automatic containers) 15:08:16 #link https://bugs.opendaylight.org/show_bug.cgi?id=2399 the bug 15:08:27 ok 15:08:29 #info we will try csit and provide a heads-up before merging 15:08:35 more topics? 15:09:29 going once 15:10:27 going twice 15:10:32 #endmeeting
