[rabbitmq-discuss] publish to empty exchange works, while publish to correct exchange doesn't

Hello everyone,

Yes, it's RPC time again. ;-)

In client:

chan.exchange_declare(exchange = rpc_res_exch,type='direct')
chan.queue_declare(queue = myqueue)
chan.queue_bind(exchange = rpc_res_exch, queue = myqueue)


Now, when I do in server:

ch.basic_publish(
    exchange = '',
    properties = pika.BasicProperties(correlation_id =
props.correlation_id + '_' + mynode),
    routing_key = props.reply_to,
    body = str(response))

... messages get delivered to 'myqueue'.

But when I do:

ch.basic_publish(
    exchange = rpc_res_exch,
    properties = pika.BasicProperties(correlation_id =
props.correlation_id + '_' + mynode),
    routing_key = props.reply_to,
    body = str(response))

... messages do NOT get delivered to the queue.

I checked with rabbitmqctl list_queues (it should show number of
messages in queue next to queue name, right?)


Can anyone please explain this mystery to me?
