Ken Giusti created DISPATCH-366:
-----------------------------------
Summary: When delivery fails the router sends the RELEASED
disposition, not MODIFIED
Key: DISPATCH-366
URL: https://issues.apache.org/jira/browse/DISPATCH-366
Project: Qpid Dispatch
Issue Type: Bug
Components: Router Node
Affects Versions: 0.6.0
Reporter: Ken Giusti
Priority: Blocker
Fix For: 0.6.0
The router does not properly distinguish between a delivery failure and
undeliverable.
In the case of a delivery failure - where the router cannot ensure that the
message wasn't consumed - the router must send back the MODIFIED terminal
disposition with the delivery-failed flag set. This is necessary as the sender
must increment the message's delivery-count if it retransmits.
In the case of an undeliverable message - where the router cannot forward a
message to the destination - the router must send back the RELEASED terminal
disposition. RELEASED informs the sender that the message was not acted upon.
The sender must not increment the message's delivery-count if it retransmits.
Currently the router uses RELEASED in both these cases.
