AttributeError: 'Channel' object has no attribute 'basic' when publish message

[dizpers]

It seems like that resetting rabbitmq helps me. RabbitMQ logs contained following:

=ERROR REPORT==== 6-Jun-2014::01:26:46 ===
connection <0.3637.0>, channel 1 - soft error:
{amqp_error,precondition_failed,
            "cannot redeclare exchange 'test_exchange' in vhost '/' with different type, durable, intern...",
            'exchange.declare'}

=WARNING REPORT==== 6-Jun-2014::01:26:46 ===
closing AMQP connection <0.3637.0> (127.0.0.1:34669 -> 127.0.0.1:5672):
connection_closed_abruptly

but the most interesting thing - that exchange declaration code doesn't changed during multiple test running =)

Likely what happened is that the channel closed between when it was declared and when you attempted to publish, likely due to the protocol error you noted. Did you find a bug in your tests or is there a problem with exchange.declare?

[dizpers]

I think exchange.declare is fine. I did't get this error since I rewrite my tests.

Closing the channel ( channel.close() ) and then calling channel.basic may cause this error

[awestendorf]

Yeah I just proposed in #61 a change to closed channels that would make it much clearer to the user.
