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)
