[jira] [Work logged] (ARTEMIS-5215) AMQP Federation Queue Consumer can leave a duplicate message on remote broker
[ https://issues.apache.org/jira/browse/ARTEMIS-5215?focusedWorklogId=954803&page=com.atlassian.jira.plugin.system.issuetabpanels:worklog-tabpanel#worklog-954803 ]

Work Description: tabish121 opened a new pull request, #5480:
URL: https://github.com/apache/activemq-artemis/pull/5480
When a pull mode federation consumer is stopped due to demand being removed and the credit tup-up handler is also awaiting the Queue backlog to clear in order to grant a new batch of credit it might exit that cycle an leave the in-progress flag set to true. Currently this likely won't trigger a stuck consumer but if the code was to be altered to hold open a link for some period of time before fully closing in order to avoid needless attach / detach cycles then it would be possible for the credit replenishment to get stuck because the previous attempt left the in-progress flag set to true.

> When local demand is removed from a federated Queue and the AMQP receiver is shutting down it needs to drain the link *and* await any pending settlements to be sent before detaching the link otherwise there is a window in which a message could be enqueued on the local broker but also released back to the queue on the remote leading to a duplicate.
