--------------------------------
Summary: [AMQP 0-10] Queue browsers increment the delivery count
Key: QPID-8098
URL: https://issues.apache.org/jira/browse/QPID-8098
Project: Qpid
Issue Type: Bug
Components: Broker-J
Affects Versions: qpid-java-broker-7.0.0, qpid-java-6.1, qpid-java-6.0,
0.32, 0.30
Reporter: Keith Wall
On the AMQP 0-10 protocol path within the Broker, deliveries to queue browsers
erroneously increase the {{MessageInstance#deliveryCount}}. This should not
happen. The purpose of the delivery count is to count deliveries to
(destructive) consumers - not browsers. The problem is restricted to AMQP 0-10
implementation. Neither AMQP 0-x nor AMQP 1.0 are affected by this defect.
The defect could mean that messages are spuriously routed to a DLQ (if
configured). For this to happen, there would need to be additional destructive
consumers on the queue that cause the message to be 'released'. Releasing
occurs during transaction rollback and client disconnection (when messages are
prefetched). The message would be prematurely routed to the DLQ in this case.
