[jira] [Updated] (AMQ-3274) duplicate messages on Temporary Topics
in network of brokers
[ https://issues.apache.org/jira/browse/AMQ-3274?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Arthur Naseef updated AMQ-3274:
-------------------------------
Attachment: tempTopicDups.patch
Patch eliminating duplicates on temporary topics. As the patch shows, subscriptions to temporary destinations were being matched against the subscriptions in permanent regions, not the temp regions.

> Key: AMQ-3274
> URL: https://issues.apache.org/jira/browse/AMQ-3274

> Creating a network of brokers, duplicate messages are being seen on Temporary Topics.
> The network configuration used is as follows:
> <networkConnectors>
> <networkConnector name="nw1_queues_from_nw2" uri="static:(tcp://127.0.0.1:60002)"
> duplex="true" conduitSubscriptions="false" dynamicOnly="true"
> networkTTL="7" suppressDuplicateQueueSubscriptions="true"
> decreaseNetworkConsumerPriority="true"
> bridgeTempDestinations="true"
> >
> <excludedDestinations>
> <topic physicalName=">" />
> </excludedDestinations>
> </networkConnector>
> <networkConnector name="nw1_topics_from_nw2" uri="static:(tcp://127.0.0.1:60002)"
> duplex="true" conduitSubscriptions="true" dynamicOnly="true"
> networkTTL="7" suppressDuplicateQueueSubscriptions="true"
> decreaseNetworkConsumerPriority="true"
> bridgeTempDestinations="true"
> >
> <excludedDestinations>
> <queue physicalName=">" />
> </excludedDestinations>
> </networkConnector>
> </networkConnectors>
> Note there are 2 duplex connections between the brokers. Changing to non-duplex connections, the problem goes away with 2 brokers in the network, but reappears when a 3rd broker is added.
> The problem only affects temporary Topics; normal Topics work fine.
> A patch will be attached. Also, a test case will be attached when it is available.
