(Sai, 16:10:05) * - Tony says it seems xml being downloaded from internet, issue may be dealing with the place where we store. (it expects xml but it downloads html) (Sai, 16:11:42) * - Tony says target/features of individual repo will have more explanation on errors (Sai, 16:12:20) * we think they're really infrastructure failures, then we should report them to helpdesk or on #opendaylight-releng here (colindixon, 16:12:47) * - colindixon says migration of nexus / other stuff shouldn't be ideally affecting these builds (Sai, 16:13:49) * colindixon says jenkins pulls from local mirror of nexus, if public nexus has any issues that explains it.

But with previous release experience it takes 2-3 releases in general (Sai, 16:19:57) * - Tony suggests to deal with deprecation after carbon (Sai, 16:20:22) * - colindixon supports it too. (Sai, 16:20:47) * - TomP suggests Nitrogen and Tony agrees. (Sai, 16:21:17) * - Documentation of necessary changes to support YANG 1.1 (Sai, 16:22:04) * LINK: - https://git.opendaylight.org/gerrit/#/c/37081/ (Sai, 16:22:11) * - Ryan requests for time frame (Sai, 16:22:27) * - The patch i just a small list, other part yang1.1 affects MD-SAl, given that we are close to M2, most likely in carbon. (Sai, 16:23:11) * - Tony says it introduces lot features , so it will be carbon. (Sai, 16:23:44) * - Ryan volunteers for any help here (Sai, 16:24:15) * - Update on Blueprint (Sai, 16:24:52) * - TomP says - there are no new updates, bu there is progress in work wrt to apache karaf with help of Stephen (Sai, 16:26:12) * - Improve config subsystem Change 36777 - is a precursor and it is ready to go.

(Sai, 16:30:42) * ACTION: - TomP will start to work on a wiki page to state how to move from config system to BluePrint (Sai, 16:34:35) * - Ryan offers help from AAA side. (Sai, 16:35:32) * - TomP suspects Netconf will be more harder wrt user configuration. (Sai, 16:36:04) * - Ryan asks if there are any people concerns , requests to raise sooner than later. (Sai, 16:37:33) * - new topics (Sai, 16:38:17) * - question on patch 37009 wrt data tree consumers / data tree producers (Sai, 16:39:21) * - colindixon says it would be very confusing to developers, say OFP could be both consumer/producer in case of writing a flow . (Sai, 16:40:12) * - colindixon asks if there is any reason we can't do it in the context. (Sai, 16:41:46) * - Robert says we are throwing away standalone one way transactions. (Sai, 16:42:20) * - Robert says it is a consistency win as well as performace win. (Sai, 16:43:18) * - colin summarizes that data tree producer is a transacation factory and it is little bit more than that because it is a transaction chain (Sai, 16:44:27) * - colindixon requests not to introduce new terminology which will confuse developers (Sai, 16:44:59) * - Robert says since these are new concepts (not similar to data broker) we need to come up with new names. (Sai, 16:46:04) * - Robert is open for contribution (Sai, 16:46:44) * - Robert says with this patch we are moving readwritetransaction entirely (Sai, 16:48:05) * - colindixon says there are somethings (like increment values) are no more possible with this approach. (Sai, 16:49:32) * - Robert says we still have exclusive ability to write to a subtree (Sai, 16:50:01) * - Robert says we can have an another producer to write to subtree (Sai, 16:50:56) * - Muthu asks will the cardinality of 1:1 will be be enforced on a subtree (Sai, 16:51:54) * - Robert says Yes, At any given time only one producer can write to subtree. (Sai, 16:52:14) * - TOny says using locking mechanism it is possible. (Sai, 16:52:50) * - colindixon summarizes if a data tree is claimed by a procuder , you will be unable to write using netconf/restconf (Sai, 16:53:28) * - Robert says it is true, but it doesn't mean we can't negotiate mechanism, but it is out of the scope of these APIs (Sai, 16:54:49) * - colindixon says there are currently applications which usess single data tree where two producers are writing at same time. (Sai, 16:56:38) * - colindixon says in an application logical part & updation of status is an example (Sai, 16:57:19) * - Robert says intrinsic race condition comes in to picture. (Sai, 16:57:55) * - Robert says the main reason to do is pushing intent in to config and pushing status in to operational (Sai, 16:59:53) * - colindixon refers to difference between networking and Software way of looking at it. (Sai, 17:00:26) * - Robert says the system is never designed or architect-ed for these purposes (Sai, 17:01:39) * - colindixon says when write transaction is done it will fail when if sub tree is gone away or moved. (Sai, 17:05:21) * - Robert requests for use case / applications so that we can move ahead (Sai, 17:05:48) * - Tony rephrases Robert and asks is there is any application in odl which does listening / writing to the same subtree at same time. (Sai, 17:07:23) * ACTION: - colindixon to work on checking out an application in odl where it listens / writes to the same subtree at same time. (Sai, 17:08:12) * - participants (Sai, 17:08:22) * - Sai / Ryan / Ajay Lele / Alexis / Andrej / Aolin / Martin Ciglan / Muthu / Robert /Shuva Kar / Stephen / Tom P / Tomas Cere / Tony / Vaclav / Viera / Vratko (Sai, 17:09:54) Meeting ended at 17:09:58 UTC.
