15:15:26 tbachman: he is saying he isn't on the webex 15:15:28 ah 15:15:29 :) 15:15:30 I think 15:15:33 ^^yeah :) 15:16:33 #info tpatellis notes that this wasn’t discussed at the dev summit; we could try to document it, but it’s still difficult to consume 15:18:41 #info jmedved says that John Burns (?) should be helping with this process 15:19:20 #info colindixon notes that there’s no obvious entry point on the wiki on how to on-board with this stuff 15:19:48 #info colindixon also notes that there are several “eras” of the MD-SAL documentation, which makes this more confusing 15:20:22 #info colindixon recommends adding things like “this is out of date” to pages that are no longer relevant. 15:20:41 #info jmedved asks how we can remove content 15:20:42 Is this info correct? https://wiki.opendaylight.org/view/Meetings#MD-SAL_Hackers 15:21:01 #info colindixon says he hates to remove content — would prefer just indicating that the content is old 15:21:36 dfarrell07: here’s the link I used https://wiki.opendaylight.org/view/OpenDaylight_Controller:MD-SAL#MD-SAL_Hackers_Weekly_Call 15:21:46 tbachman: Thanks! :) 15:21:50 np! :) 15:22:40 #info jmedved says we should make clear that the config system and MD-SAL are two different components 15:23:12 #info colindixon says we need to break up the MD-SAL documentation (i.e. two people working for two weeks isn’t sufficient) 15:24:35 #action alagalah says that he’ll take his recommmendations/links from last weeks, and stuff from tpatellis, and publish a list of concrete things that need to happen using bugzilla 15:24:54 thanks for scribing tbachman 15:25:37 you rock 15:25:37 colindixon: np! :) 15:25:39 #info jmedved notes that even with documentation, it’s still difficult to use, and asks what else we can do to improve the learning curve 15:26:12 #info alagalah says that there are a number of folks who have the “tribal knowledge”, who could investigate writing stuff up on their speciality. 15:27:08 #info jmedved says that rovarga_ ttkacik, and tpatellis are on the call, and wonders if we can assign each of them an action to come up with a set of recommendations for usability by next week 15:27:18 tbachman: Specifically it was around what are the gaps, not producing a writeup 15:27:27 tbachman: That is a MUCH larger task 15:27:27 alagalah: thx! 15:27:36 #undo 15:27:36 Removing item from minutes: 15:27:45 tbachman: Are you going to ACTION it ? 15:28:17 I added this meeting to the wiki and gcal https://wiki.opendaylight.org/view/Meetings#MD-SAL_Hackers 15:28:22 #info jmedved says that rovarga_ ttkacik, and tpatellis are on the call, and wonders if we can assign each of them an action to identify the gaps we currently have for better usability by next week 15:28:28 alagalah: will do, once folks agree ;) 15:29:02 #info tpatellis says he can identify the pain points, but not yet solutions 15:29:18 #info alagalah will also provide his pain points 15:30:11 #action alagalah to come up with his list of adoption pain points by next meeting 15:30:25 alagalah: was going to do it in a single one :) 15:30:31 #action alagalah to take what he has done so far on the documentation front and break it into chunks 15:30:45 tbachman: Not sure how meetbot works in terms of multiple IDs in one Action verb 15:31:01 alagalah: good point 15:31:14 * tbachman will have to investigate that 15:31:54 * tbachman missed what it was that colindixon was going to do 15:33:47 #action colindixon to send e-mail noting his pain points: (1) it’s hard to figure out how to take the yang file for the config subsystem and translate it into an XML file, and (2) the config yang file is compiled in a different way than yangtools does 15:33:53 colindixon: thx! 15:33:55 tho are you chair? 15:34:04 ah 15:34:06 you started it :) 15:34:07 tbachman: I am the chair, you are too 15:34:07 lol 15:36:39 #info colindixon says that config subsystem probably causes the largest amount of difficulty, but is probably encoutered less often than RPCs and notifications, which may affect what we prioritize as far as documentation 15:37:46 #info uchau asks if the config subsystem is just a “recommended thing to use”, or if it’s really a requirement 15:38:50 #info colindixon says it would be hard for us to mandate using the config subsystem 15:39:48 #info colindixon says that the config subsystem enforces loading order within config subsystem components, but is a separate loading system than OSGI 15:43:31 #info jmedved says that for a system integrator, having a uniform way of managing the components is critical, and therefore we should adopt some conventions on how these things are done 15:45:10 #info rovarga_ says we could create a shim layer on top of the config system, reducing the use cases, to simplify the APIs and concepts, simplifying the user’s interaction with it 15:46:46 #action rovarga_ to write an email describing why the things in the config subsystem are the way they are 15:49:06 #info colindixon asks why the config subsystem is necessary to do clustering (will also go read last week’s meeting minutes, as this was covered there) 15:51:35 #info tpatellis says that the config subsystem could be used as a mechanism for bringing apps down and back up when critical pieces like the data store fail 15:52:26 #info rovarga_ says that trying to understand the dependency graph in something like OSGI is challenging if not impossible, whereas the config subsystem provides some constructs to understand this 15:54:35 #info alagalah says that we need to provide background on all the pieces for ODL (config subsystem, MD-SAL, karaf, etc.) — not just background and how to use them, but when and why. 15:55:14 #info colindixon says there are probably different categories of users that we want to target this towards (i.e. depends on knowledge and use case) 15:58:45 #info colindixon believes that whatever we select as the priority, it’s probably best to use an “all-hands-on-deck” approach in order to get good documentation 16:00:30 #info colindixon asks if folks can pick up an item on the list that alagalah publishes, and indicate that they’ve picked it up 16:00:35 #action keith send out a list of things to do; if people have cycles, pick up the item on the list a nd run with it 16:00:48 #action tom p: list painpoints 16:01:06 #action alagalah send out a list of things to do; if people have cycles, pick up the item on the list a nd run with it 16:01:07 #action alagalah to send out a list of things to do; if people have cycles, pick up the item on the list and run with it 16:01:10 lolz 16:01:12 I have to drop 16:01:13 sorry 16:01:16 Same here 16:01:19 #action tpatellis to provide a list of pain points 16:01:21 #action robert varga: email with background design info on configu subsystem 16:01:24 tbachman: and I have a meeting. 16:01:48 #action robert v: couple of imprvoement/simplification proposal -email 16:01:49 #action rovarga_ email with background design info on configu subsystem 16:02:07 #action couple of imprvoement/simplification proposal -email 16:02:40 #action jmedved to start background architecture wiki using keith’s documentation 16:03:47 #action jmedved start architecture section for config subsystem on wiki 16:04:02 #action jmedved start architecture section for config subsystem on wiki 16:04:20 #action uyen collect pain points from hp folks and send to keith 16:04:30 #action uchau collect pain points from hp folks and send to keith 16:04:34 #info all action items sent to keith, copied folks on the call 16:04:37 #endmeeting
