Timothy Bish commented on AMQNET-323:
-------------------------------------
Redelivery is a local operation for the client, so deleting the message at the
Console will have no effect on the client regardless of whether its correctly
dealing with the TTL value or not.
> NMS Client does not respect TimeToLive with Listener callback
> -------------------------------------------------------------

> Key: AMQNET-323
> URL: https://issues.apache.org/jira/browse/AMQNET-323
> Project: ActiveMQ .Net
> Issue Type: Bug
> Components: ActiveMQ, NMS
> Affects Versions: 1.5.0
> Environment: Windows 7
> Reporter: Matthew Good
> Assignee: Jim Gomes
>
> When TimeToLive expires while a listener is in a redeliver loop, the
> redelivery never stops. The following unit tests show this. The first unit
> test uses Receive and it works fine. The second uses a listener and it fails.
> I added these tests to AMQRedeliveryPolicyTests
> [Test]
> public void TestNornalRedeliveryPolicyOnRollbackUntilTimeToLive()
> {
> using(Connection connection = (Connection) CreateConnection())
> {
> IRedeliveryPolicy policy = connection.RedeliveryPolicy;
> policy.MaximumRedeliveries = -1;
> policy.InitialRedeliveryDelay = 500;
> policy.UseExponentialBackOff = false;
> connection.Start();
> ISession session =
> connection.CreateSession(AcknowledgementMode.Transactional);
> IDestination destination = session.CreateTemporaryQueue();
> IMessageProducer producer =
> session.CreateProducer(destination);
> IMessageConsumer consumer =
> session.CreateConsumer(destination);
> // Send the messages
> ITextMessage textMessage = session.CreateTextMessage("1st");
> textMessage.NMSTimeToLive = TimeSpan.FromMilliseconds(800.0);
> producer.Send(textMessage);
> session.Commit();
> ITextMessage m;
> m =
> (ITextMessage)consumer.Receive(TimeSpan.FromMilliseconds(1000));
> Assert.IsNotNull(m);
> Assert.AreEqual("1st", m.Text);
> session.Rollback();
> // No delay on first Rollback..
> m =
> (ITextMessage)consumer.Receive(TimeSpan.FromMilliseconds(100));
> Assert.IsNotNull(m);
> session.Rollback();
> // Show subsequent re-delivery delay is incrementing.
> m =
> (ITextMessage)consumer.Receive(TimeSpan.FromMilliseconds(100));
> Assert.IsNull(m);
> m =
> (ITextMessage)consumer.Receive(TimeSpan.FromMilliseconds(700));
> Assert.IsNotNull(m);
> Assert.AreEqual("1st", m.Text);
> session.Rollback();
> // The message gets redelivered after 500 ms every time since
> // we are not using exponential backoff.
