Subject [jira] Created: (QPID-959) Protocol renegotiation does not occur on failover
Date Thu, 24 Apr 2008 08:57:21 GMT
Protocol renegotiation does not occur on failover
-------------------------------------------------

                 Key: QPID-959
                 URL: https://issues.apache.org/jira/browse/QPID-959
             Project: Qpid
          Issue Type: Bug
    Affects Versions: M3
            Reporter: Aidan Skinner
             Fix For: M3


The current failover mechanism does not fully take account of the fact that a session may
change protocol versions when failover occurs. Consider:

Broker A is a 0-10 broker
Broker B is a 0-9 broker
Client C is a 0-8, 0-9 and 0-10 capable client

1. C connects to A, with B configured as as it's second broker, with round robin failover.
It negotiates to use 0-10 and begins messaging. 
2. Broker A fails and C connects to Broker B. It should renegotiate the protocol and start
talking AMQP 0-9. Messaging should continue as transparently as possible. 
3. Broker B fails and C connects to Broker A. It should renegotiate the protocol and resume
talking AMQP 0-10, messaging should continue.

Currently step 2 will fail
