About
This is a fork of amqplib which was originally written by Barry Pederson. It is maintained by the Celery project, and used by kombu as a pure python alternative when librabbitmq is not available.
This library should be API compatible with librabbitmq.

Differences fromSupports draining events from multiple channels (
Connection.drain_events
)Support for timeouts
Channels are restored after channel error, instead of having to close the connection.
Support for heartbeats
Connection.heartbeat_tick(rate=2)
must called at regular intervals (half of the heartbeat value if rate is 2).- Or some other scheme by using
Connection.send_heartbeat
.
- Supports RabbitMQ extensions:
- Consumer Cancel Notifications
- by default a cancel results in
ChannelError
being raised - but not if a
on_cancel
callback is passed tobasic_consume
.
- by default a cancel results in
- Publisher confirms
Channel.confirm_select()
enables publisher confirms.Channel.events['basic_ack'].append(my_callback)
adds a callback to be called when a message is confirmed. This callback is then called with the signature(delivery_tag, multiple)
.
- Exchange-to-exchange bindings:
exchange_bind
/exchange_unbind
. Channel.confirm_select()
enables publisher confirms.Channel.events['basic_ack'].append(my_callback)
adds a callback to be called when a message is confirmed. This callback is then called with the signature(delivery_tag, multiple)
.
- Exchange-to-exchange bindings:
Support for
basic_return
- Uses AMQP 0-9-1 instead of 0-8.

-> ChannelError``Connection.known_hosts
removed.Connection
no longer supports redirects.exchange
argument toqueue_bind
can now be empty to use the "default exchange".
Adds
Connection.is_alive
that tries to detect whether the connection can still be used.Adds
Connection.connection_errors
and.channel_errors
, a list of recoverable errors.Exposes the underlying socket as
Connection.sock
.Adds
Channel.no_ack_consumers
to keep track of consumer tags that set the no_ack flag.Slightly better at error recovery
