Pavel Moravec created DISPATCH-158:
--------------------------------------

             Summary: Dispatch should ignore frames after receiving close frame
                 Key: DISPATCH-158
                 URL: https://issues.apache.org/jira/browse/DISPATCH-158
             Project: Qpid Dispatch
          Issue Type: Bug
          Components: Router Node
    Affects Versions: 0.4
            Reporter: Pavel Moravec
            Priority: Minor


(not sure if component matches, or if the bug isn't in proton, please change accordingly)

Having a client / mobile subscriber receiving messages that suddenly closes the AMQP1.0 connection by sending "close" performative, the dispatch has to ignore any further performatives on the connection (ideally raising a warning). And it should not forward them further.

See https://issues.jboss.org/browse/ENTMQCL-14 for an example of malfunctioning client that sends close frame followed by flow frame (against AMQP spec). Dispatch then forwards the flow frame (with invalid channel number 65534 and invalid handle 4294967294) before closing the AMQP connection. This flow should not be forwarded but ignored - dont propagate misbehaviour in AMQP 1.0 communication.

(dispatch router does not violate AMQP1.0 spec, "just" reacts on such violation by sending wrong and ridiculous flow frame)
