Lionel Cons commented on ARTEMIS-1794: -------------------------------------- The use case is the following. We have many ActiveMQ 5 STOMP clients that use topics and queues. In order to ease the transition from ActiveMQ 5 to Artemis, we would like to avoid having to change the destination names used by all these clients. So we would need to have {{/topic/foo}} behaving like a topic and {{/queue/foo}} behaving like a queue, like we have now. Some destination names are dynamic and not known in advance so they cannot be declared beforehand in {{broker.xml}}. The acceptor prefixes were a perfect match for this use case... Since a topic named {{foo}} is completely independent from a queue named {{foo}}, maybe they should not share the same address. What about not stripping the acceptor prefixes to derive the address names? > Confusion when auto removing a queue > ------------------------------------ > > Key: ARTEMIS-1794 > URL: https://issues.apache.org/jira/browse/ARTEMIS-1794 > Project: ActiveMQ Artemis > Issue Type: Bug > Components: STOMP > Affects Versions: 2.5.0 > Reporter: Lionel Cons > Priority: Major > > I'm using the following settings to try to mimic ActiveMQ 5 STOMP destination > handling: > {code} > <acceptor > name="stomp">tcp://0.0.0.0:61613?tcpSendBufferSize=1048576;tcpReceiveBufferSize=1048576;protocols=STOMP;useEpoll=true;anycastPrefix=/queue/;multicastPrefix=/topic/</acceptor> > {code} > This works as expected in most situations. > However, when subscribing to a queue (via {{destination:/queue/foo}}) and > sending a message to an eponymous topic ({{destination:/topic/foo}}) Artemis > reports a fatal error: > {code} > AMQ119209 Can't remove routing type ANYCAST, queues exists for address foo. > Please delete queues before removing this routing type. > {code} > I guess this happens when it tries to auto delete things. > Doing the opposite (subscribing to the queue and sending a message to the > topic), I get the same kind of error: > {code} > AMQ119209 Can't remove routing type MULTICAST, queues exists for address foo. > Please delete queues before removing this routing type. > {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
