Keith Wall commented on QPID-4162:
----------------------------------
As the client should be allowed to session.close() whenever it likes
(regardless of what commands are already on the wire), I see this as a Java
Broker issue. It does not respect the AMPQ 0.10 spec:
{quote}
The transport MUST be attached in order to use any control other than "attach",
"attached", "detach", or "detached". A peer receiving any other control on a
detached transport MUST discard it and send a session.detached with the
"not-attached" reason code.
{quote}
The _Broker_ gets its current behaviour (throw the PVE) from QPID-2176 (I'm not
certain if this was intentional as this Jira was resolving a client defect. I
think we should change to Broker to conform to the spec i.e. return a
SessionDetached control with SessionDetachCode.NOT_ATTACHED reason. The Python
implementation connection.py line 101 already has the appropriate guards in
place to safely ignore the 'extra' SessionDetached control.
I tested this change locally, and it appears to resolve the issue.
Any thoughts?
