[jira] [Created] (AMQ-3937) watchTopicAdvisories=false doesn't work
when a consumer is subscribing to a composite topic
Martin Chan Shu Ching created AMQ-3937:
------------------------------------------
Summary: watchTopicAdvisories=false doesn't work when a consumer is subscribing to a composite topic
Key: AMQ-3937
URL: https://issues.apache.org/jira/browse/AMQ-3937
Project: ActiveMQ
Issue Type: Bug
Reporter: Martin Chan Shu Ching
When watchTopicAdvisories=false is set in ActiveMQConnectionFactory, all connection created from it will NOT listen to any advisory topics. However, when the connection is for subscribing to a composite topic, the associated advisory topic will still be listened!
e.g.
1. consumer listens to TopicA,TopicB
2. advisory topic ActiveMQ.Advisory.Consumer.Topic.TopicA,TopicB will be created in AdvisoryBroker.addConsumer()
3. then AbstractRegion.addConsumer() will call DestinationMap.get(), in where when the key is TopicB, answer with value 'ActiveMQ.Advisory.Consumer.Topic.TopicA,TopicB' will return.
Therefore, the consumer will listen to "ActiveMQ.Advisory.Consumer.Topic.TopicA,TopicB", "TopicA" and "TopicB". As such the connection still listens to an advisory topic!

--------------------------------------------
True. But that will disable the advisories for the whole broker. In fact, what i want is to have only a single dedicated application that listens to the advisories for analysis.

---------------------------------
watchTopicAdvisories=false is just for specific temp destination advisories so that a connection can know about temp dests without a round trip to the broker.
If you want to disable advisories, use the broker attribute advisorySupport=false

Gary Tully commented on AMQ-3937:
---------------------------------
An ActiveMQConnection *only* listens to the temp advisory topic and only when watchTopicAdvisories=true
The Advisory Topics are created on demand when the AdvisoryBroker sends messages to those topics, but there needs to be explicit consumers.
You can disable most advisories via destination policy
Note all of the boolean advisory* attributes in
http://svn.apache.org/viewvc/activemq/trunk/activemq-core/src/main/java/org/apache/activemq/broker/region/policy/PolicyEntry.java?view=markup
I am not sure there is any bug here?
