[jira] [Updated] (ARTEMIS-4794) CoreBridge: Duplicate message when bridge is stopped while messages being consumed by target node
[ https://issues.apache.org/jira/browse/ARTEMIS-4794?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
nmeylan updated ARTEMIS-4794:
-----------------------------
Summary: CoreBridge: Duplicate message when bridge is stopped while messages being consumed by target node (was: CoreBridge: Duplicate message when bridge is stopped while messages being consumed)
> CoreBridge: Duplicate message when bridge is stopped while messages being consumed by target node

> Key: ARTEMIS-4794
> URL: https://issues.apache.org/jira/browse/ARTEMIS-4794
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Clustering
> Affects Versions: 2.30.0, 2.34.0
> Reporter: nmeylan
> Priority: Major
> Attachments: BridgeDuplicateMessagesARTEMIS4794Test.java
>

> +Attached test +{*}BridgeDuplicateMessageBugTest.java{*}+ highlights the issue with+ org.apache.activemq.artemis.core.server.cluster.impl.BridgeImpl
> Place it under _tests/integration-tests/src/test/java/org/apache/activemq/artemis/tests/integration/cluster/bridge_
> {*}Summary{*}:
> When a bridge is stopped while messages being consumed by the target node, it can lead to duplicate messages.
> {*}Description{*}:
> When Using bridge and programmatically *stopping* or *pausing* it while messages are being consumed by the target node, the source node fails to get the acknowledgement from target node and messages now exists on the source and the target node.
> It appears that the "active" flag being set to false when BridgeImpl.StopRunnable is called prevent message to be acknowledged by
> _BridgeImpl::sendAcknowledged_ function
> {*}Context{*}:
> This bug appear in my code because is start and stop Bridge programmatically to move messages from one node to another when some conditions are met, if they are no longer met I want to stop the moving of messages.
>
> *Notes:*
> * Changing bridge configuration {_}useDuplicateDetection{_},{_}confirmationWindowSize{_} or _producerWindowSize_ parameter do not help to mitigate the issue
> * Not related to large messages, i use large messages in my test to ease reproduction
> * Bug present on 2.30 and 2.34
>
> *Resolution:*
> Maybe _StopRunnable::run_ should wait until _queue.getDeliveringCount() == 0_ after removing consumer but before going further in the stop process
