Cliff Jansen created QPID-7679: ---------------------------------- Summary: Memory leak in DirectExchange Key: QPID-7679 URL: https://issues.apache.org/jira/browse/QPID-7679 Project: Qpid Issue Type: Bug Components: C++ Broker Affects Versions: qpid-cpp-0.34 Reporter: Cliff Jansen Assignee: Cliff Jansen
The Exchange::unbind call for DirectExchange is coded assuming that the binding actually exists. If the binding does not exist, this has the side effect of creating a Bindingkey in the BindingKey map that remains in the map until broker exit. The management count of bindings is not updated so there is no indication there of the problem. A well behaved 0_10 program that creates a queue, creates a direct binding, deletes the binding and then deletes the queue results in a second implicit unbind when the queue is deleted (usually on the QueueDeleteBody, but if an autodelete queue, it can also happen on the MessageCancelBody ending a subscription). TopicExchange and FanOutExchange explicitly guard against non-existence of the binding/queue pair on unbind(). Presumably, DirectExchange should do the same. HeadersExchange doesn't check but doesn't "remember" the pair. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
