Re: [OpenDaylight TSC] OpenFlow Plugin and OpenFlow Java Library merge status

Yeah, i think it should be fine, until and unless someone directly consuming the openflowjava libraries ( i am not aware of, atleast in upstream).

Abhijit, would it be safe to remove OpenFlowJava Project from Nitrogen Autorelease?

 

Thanh, could you submit a patch to remove openflowjava and hopefully the build completes successfully.

 

Best Regards,

An Ho

Thanks for the update. It sounds like things are going pretty smoothly.

Hi TSC, Infra, Release, OpenFlow Java Library & OpenFlow Plugin,

 

As you probably know OpenFlow Java Library & OpenFlow Plugin projects had decided to merge in Nitrogen. Specifically the OpenFlow Java Library project codebase has been merged into the OpenFlow Plugin project - and the impacts to downstream projects have been resolved. OpenFlow Java committers also voted to archive the project. A termination proposal [5] has been created with a two week notice.

 

More details on the OpenFlow Plugin and OpenFlow Java Library merge from Tomas Slusny & Michal Rehak:

 

What was done:

---------------------

* Discussion about merging OpenFlowJava to OpenFlowPlugin was initiated here: [0]

* Weather report for merge was created here: [1]

* OpenFlowJava latest HEAD ([2]) was merged to OpenFlowPlugin repository master branch (Nitrogen) in this patches: [3]

* All references to OpenFlowJava in OpenFlowPlugin was replaced with consumed code, 

   odl-openflowjava-all feature was removed, but odl-openflowjava-protocol remained same

* OpenFlowJava project is not going to participate in Nitrogen release as it was consumed by OpenFlowPlugin

* Vote [6] on OpenFlow Java Library mailing list to archive the project - with a two week termination notice

* A termination proposal [5] for OpenFlow Java Library has been created as per archival process [4]

 

 

What needs to be done:

--------------------------------

* OpenFlowJava master (Nitrogen) branch needs to be locked/archived. Tomas will follow up with the infra for this.

* Update OpenFlowJava wiki with informations about the merge

* Create wiki page for OpenFlowPlugin with informations about the merge and about changes in structure to help 

   contributors that was contributing to both OpenFlowPlugin and OpenFlowJava

 

Please let us know if you need more info.

 

- Abhijit

I talked with Jozef and Tomas right now - and we think it will be good to discuss this in the Monday OpenFlow Plugin meeting this process (steps provided by Andy, the process followed by Sam/NetVirt when they consumed VPN Service into NetVirt, history, etc.). That way we can ensure it is done right - have all the OpenFlow Plugin committers vote during the meeting if needed. And then initiate OpenFlow Java vote. Hence we will greatly appreciate if Andy (Grimberg) and Sam Hague can join the meeting. The meeting details are here:

Agree with you Ed about having a vote in OpenFlow Java committer community - and in general the TSC role if we plan to archive. Had planned on that based on how we have decided to proceed (based on Tomas's study of impact). Unfortunately I have been offline for periods of time during the last week or two (on a vacation). Tomorrow (Wednesday) I will be meeting Jozef Bacigal (OpenFlow Java & Plugin committer) and Tomas Slusny (OpenFlow Plugin committer working on this) to understand the latest status on how this has evolved and based on that will figure out the best course of action (after discussing with the other OFP/OFJ committers).

Abhijit,

        This strikes me as good news overall.  It might be a good idea to get a vote from the OpenflowJava Committers, particularly as they will need to vote to archive the openflowjava project, and it also makes everything very clear.  As to the TSCs role, it has one for archiving the openflowjava project, and it would have one if there was some dispute with the openflowjava committers (which does not appear to be the case).   All of that said, it is probably courteous to inform the TSC :)

        Thank you for guiding this process :)

 

Ed

We kept history when we split ovsdb/netvirt and then merged netvirt
and vpnservice. The flow Andy used copied all the files into NetVirt
and the history was kept intact. I think I came up with the commands
to use and Andy did the work - but I can't find those emails right
now.

You should also stop the jobs running for the old openflowjava repo
and migrate them to use openflowplugin repo.

Yes, this is what we did - just pulled in the relvant docs to netvirt.
