 Description   

Stack trace below and logs attached. Marking this as critical since it is killing some pretty core functionality for us. Netvirt's neutron ml2 driver, networking-odl, relies by default on websocket notifications for port statuses.

It's believe this bug is causing openstack instances 4+ minutes to become
ACTIVE. Because of this, we have increased our polling timeout to 600s
in our robot CSIT. Once this bug is resolved, we need to verify the robot
CSIT is seeing faster times for instances to move to ACTIVE state and we
need a robot CSIT patch to reduce the timeout from 600s to 30s.

Is this a blocker for nitrogen? Please confirm. Thanks!

Comment by Robert Varga [ 05/Sep/17 ]

Yes, it is. It boils down to jackson not being able to parse a string XML – this is so not needed.

We already have the data in NormalizedNode format, hence instead of transcoding XML text, that should be thrown away and normal NormalizedNode->JSON encoding should be done.

That will ditch jackson, rendering the issue impossible.

Do we have an ETA on when we can merge a patch into nitrogen? Thanks!

Comment by Stephen Kitt [ 07/Sep/17 ]

https://git.opendaylight.org/gerrit/62811 is a workaround, but it might not be appropriate because of the bundle refresh issues we had with org.json in the past.

I'm working on a proper serialization which will avoid the XML-to-JSON issue altogether, but it will take a bit more time.

https://git.opendaylight.org/gerrit/62849 for Nitrogen.

The fix looks good. It was verified in sandbox.

Comment by Stephen Kitt [ 13/Sep/17 ]

The workaround has been merged. https://bugs.opendaylight.org/show_bug.cgi?id=9154 tracks the JSON serialisation rewrite.
