[rabbitmq-discuss] [PATCH] Add exclusive queue support to stomp adaptor

[Steve Powell]

Dear Jeff,

Now that I understand this (thanks Tony) I can see your patch is
appropriate.

I would want to understand the header 'exclusive' you propose is OK.
If activemq uses this header and it means the same thing there, then
I am satisfied.

If you specify exclusive:true on the SUBSCRIBE frame, then the
subscription will only be created if there are no other Consumers for
that queue. (Hold on, there may not be a queue; but yes, there is always
some queue; and yes, exclusive need not have any force for all cases, but
it seems OK in those cases. As you were.)

If there is another consumer/subscriber (anywhere) then we will send
an ERROR frame back, and the subscription is not created.

I have raised a bug (24832) for this.
