*** openstack changes topic to " (Meeting topic: dragonflow)"09:00
openstackThe meeting name has been set to 'dragonflow'09:00
gsagieAnyone else for the dragonflow meeting beside nick-ma and Shlomo?09:00
nick-mahi, all.09:00
gsagieShlomo_N: please tell Yuli to join as well09:01
gsagie#topic security groups09:02
*** openstack changes topic to "security groups (Meeting topic: dragonflow)"09:02
gsagieok so we dont have alot of people here but lets try to go over the important points09:02
Shlomo_Nok09:02
gsagieI have proposed a new security group design which combine some ideas we brought up and combine it with dingboopt design09:02
gsagie#link security group new design https://review.openstack.org/#/c/261903/09:03
gsagienick-ma: basically it has some nice ideas how to implement security groups very efficiently both in the data plane but also in the control plane, no need to sync and manage all these ipsets09:03
gsagieso i believe this is going to be a good solution, but please review and let me know your comments/ideas09:04
gsagiemaybe i missed something09:04
nick-mayes, i'm reviewing.09:04
gsagieok great, feel free to ask in #openstack-dragonflow or email if you have any questions09:04
gsagiedingboopt is here?09:04
dingbooptyes09:05
yuli_sI am here09:05
gsagiedingboopt: anything you would like to update regarding the security groups work?09:05
dingbooptcurrently no09:06
gsagiedo you feel you can start working on the code yet? i think that regardless of which design, we still need to populate the DF DB with all the security group configuration from the Neutron plugin09:06
gsagiewould you like to start working on that as we review the design?09:06
dingbooptyes09:06
dingbooptI can start working on the code09:06
*** shz has joined #openstack-meeting-409:07
shzo/09:07
gsagie#action dingboopt start working on DF neutron plugin to configure security groups data to DF DB09:07
gsagieHi shz o/09:07
gsagie#info shz, dinboopt, nick-ma, yuli_s, Shlomo_N in dragonflow meeting09:08
*** BillyXu has joined #openstack-meeting-409:08
gsagieok, so we can start with that, this is work that needs to be done anyway and we can iterate on the security group spec in the mean time09:08
gsagiehi BillyXu, thanks for joining09:08
gsagieanyone would like to add anything else regarding security groups? or have any question?09:09
shzhi gsagie, I think sg is need for dragonflow, but it shoulb be done at current time?09:09
yuli_sgsagie: I submited by comments09:09
gsagieshz: what do you mean?09:09
gsagieshz: we must work on security groups its a needed feature, and i think most of the parts we need for it are there09:10
shznow I think we should focus on making l2/l3 stable09:10
BillyXuyuli_s: yes, see your comments09:11
shzgsagie, I agree09:11
gsagieshz: yes i agree, we do this in parallel09:11
gsagieshz: our next topic is testing :)09:11
shzok :)09:11
gsagie#action gsagie, dingboopt  continue and iterate on the security group design09:12
gsagie#topic testing09:12
*** openstack changes topic to "testing (Meeting topic: dragonflow)"09:12
gsagieok so regarding testing, we have some good patch from yuli_s that adds a nice idea to fullstack tests09:12
shzwe need unit terst :)09:12
yuli_sYes, it is here09:13
gsagie#info fullstack tests - https://review.openstack.org/26100109:13
yuli_shttps://review.openstack.org/261001/09:13
gsagieshz: i agree, we need to start adding unit tests (we have fullstack/tempest and rally integration)09:13
gsagieanyone can work on unit tests? shz any chance?09:13
gsagieeven just few examples so we can continue and iterate on it09:14
shzdo ohter have any idea?09:15
gsagieShlomo_N: you were suppose to start working on it, are you close to finish with RethinkDB?09:15
Shlomo_NI think I am, still working on it.09:15
gsagieyuli_s: you need to add more tests for port creation/deletion as well09:15
gsagie#action yuli_s add tests for VM port creation/deletion to fullstack tests09:15
yuli_sOk,09:16
gsagieok, i will start writing some unit tests examples and Shlomo_N can continue when he finish and then anyone thats adding new feature will write there own tests09:16
gsagie#action gsagie start writing some unit tests examples for Dragonflow09:16
Shlomo_Ngreat :)09:16
gsagieWe also need to investigate some tempest tests that we exclude09:17
gsagiethere arent many but we need to make sure no one that relates to us fails09:17
gsagieAnyone would like to check it out?09:17
gsagiei will put it on me for now, but if anyone wants to take some work please let me know by next meeting09:18
gsagie#action gsagie fix failing tempest tests09:18
shzgsagie, thx for your hard work09:18
nick-mado you have the blacklist of tempest tests that fail with df?09:18
gsagieRegarding scale we still need to test both data path and control path with projects like Shaker/VMTP and scale environments09:19
gsagienick-ma: the excluded tests are in devstackgaterc file (in devstack folder)09:19
gsagienick-ma: but many of the excluded tests are either not relevant for networking or not related to Dragonflow, so the first task will be to find which tests we actually need to solve09:20
gsagienick-ma: any update on the scale env? or its too early?09:21
nick-maok. i will review it when i finish zookeeper support. maybe before next meeting, i'm not sure.09:21
gsagienick-ma: thats great, thank you09:21
gsagie#action nick-ma help review failing tempest tests09:21
*** salv-orlando has joined #openstack-meeting-409:22
nick-makun_huang is preparing, afaik.09:22
gsagiekun_huang: here by any chance?09:22
nick-mai think it takes time.09:23
gsagienick-ma: yeah, for sure09:23
gsagienot easy to bring these enviorments09:23
gsagie#action gsagie verify with kun_huang progress on scale env09:24
gsagie#action gsagie Write test plan for scale and performance testing on control and data path09:24
gsagienick-ma: there are some tests that we are planning to do which are not only related for scale, L3 performance with projects like VMTP/Shaker can already be tested09:24
gsagieand we can start tunning the pipeline09:24
gsagieAlso we are planning to create a small automated framework to test various DBs behavior and performance09:25
gsagie#action gsagie work with Aharon to define test framework for DB drivers and servers09:25
gsagieok, before we move to the next topic, anyone has anything else for testing?09:26
gsagie#topic DB09:26
*** openstack changes topic to "DB (Meeting topic: dragonflow)"09:26
gsagieok, noticed some great work from nick-ma on adding zookeeper driver09:27
gsagie#info nick-ma adding Zookeeper driver, review patch - https://review.openstack.org/26173109:27
gsagienick-ma: want to update us how thats going?09:27
gsagiethe path i put above is just first part to make clustering configurable09:28
nick-mai've finished the demo today, but it still needs testing locally.09:28
gsagienick-ma: cool, very interested to see it :)09:28
gsagiethanks for working on that!09:28
nick-mai just sent out an email discussing the cluster configuration. feel free to reply, thanks.09:28
*** gampel has joined #openstack-meeting-409:29
gsagienick-ma: ok havent seen yet, i will look09:29
gsagie#action nick-ma working on zookeeper DB driver09:29
gsagieShlomo_N: any update on RethinkDB patch?09:29
Shlomo_NI found the problem, probaly will upload a patch today.09:30
Shlomo_NThis will allow using rejoin-stack for rethinkDB09:30
gsagieok, once that is done you can start with the unit tests part09:30
gsagiegreat, good job Shlomo09:31
Shlomo_NI know09:31
Shlomo_Nthank you :-)09:31
gsagie#info Shlomo_N upload fix for rethinkDB rejoin stack09:31
gsagie#info RethinkDB to merge by next meeting09:31
gsagieAnything else on the DB?09:31
Shlomo_NAny1 tested RAMcloud for rejoin?09:32
gsagieShlomo_N : RAMCloud is a little bit trickier as it saves everything in RAM, we decided previous week that we will wait with it09:32
gsagieI will talk with Aharon about it09:32
gsagie#action gsagie Investigate RAMCloud rejoin stack options09:33
*** tobe has joined #openstack-meeting-409:33
Shlomo_Nanyway it should allow running rejoin09:33
gsagie#topic publish-subscribe09:33
*** openstack changes topic to "publish-subscribe (Meeting topic: dragonflow)"09:33
*** bobh has joined #openstack-meeting-409:33
gsagieShlomo_N: yes, but testing is more urgent at this point, RAMCloud must always have a server that is online09:34
gsagieotherwise all data is lost as its not writing it to disk09:34
gsagiewe will talk about it in the next meeting, i think that tests are more important at this point in time09:34
gsagiejust to update, if you noticed i have started adding some pub-sub code, its still WIP09:35
gsagiei will write a detail design about it soon and upload, the idea is to abstract between the DB and the publish-subscribe mechanism when the end goal is to be able to only notify relevant information per compute node and not sync all09:35
nick-maok. i noticed. if you can provide some spec to review? it should be awesome :-)09:35
gsagiethe configuration to all the nodes09:35
gsagienick-ma: yeah i will write it by next meeting09:36
gsagie#action gsagie write spec about publish-subscribe abstraction09:36
gsagieI will describe the advantages with this approach, but anyway its going to be optional, so you dont have to use it if you dont need it09:36
gsagiebut it has some advantages, first to DB's that dont have buildin publish-subscribe and it will be easier to optimize and sync the nodes only with the needed configuration09:37
gsagiei will write all about it09:37
gsagie#action Shlomo_N upload fix for RethinkDB rejoin_stack09:37
gsagie#action Shlomo_N start working on unit tests09:37

gsagienick-ma: thanks, will take a look at it09:42
Shlomo_NMost (if not all) of the bug I opened aren't prioritized, I think we have to set priorities to bugs.09:43
gsagiewe do have a bug for rollbacks, but will take a look at this09:43
gsagieShlomo_N: do you have access to do it?09:43
Shlomo_Nno09:43
nick-mayes, i think so.09:43
