[rabbitmq-discuss] (Lightweight) Publisher Confirms with the pika Python client

[Mark Aufflick]

Hi all,

I have seen reference in passing on this list that all clients (except the C
client) support the lightweight publisher confirms (ie.
http://www.rabbitmq.com/blog/2011/02/10/introducing-publisher-confirms/).

I can't quite work out what this means in terms of using the Python pika
client. Firstly, creating a channel like so:

parameters = pika.ConnectionParameters('foo')
connection = BlockingConnection(parameters)
channel = connection.channel()
channel.queue_declare(queue='test', durable=True,
                     exclusive=False, auto_delete=False)


I'm then not sure how to put it into confirm mode. The java api seems to
have a selectConfirm() method that I don't see in the pika docs or source.

Once I have been able to put the channel into confirm mode, I then somehow
need to set the ack and nack callbacks. I see the channel.add_callback()
method, but the auto-generated (I'm guessing) docs are fairly opaque.

Hoping someone can shed some light on this? I'm also wondering if there is
an easy way to do a blocking publish that waits for the ack/nack and returns
success/failure.

Thanks,

Mark.
