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 from amqplib

• Supports draining events from multiple channels (Connection.drain_events)

• Support for timeouts

• 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 to basic_consume.

  • Publisher confirms

• Support for basic_return

• Uses AMQP 0-9-1 instead of 0-8.

  • Channel.access_request and ticket arguments to methods removed.
  • Supports the arguments argument to basic_consume.
  • internal argument to exchange_declare removed.
  • auto_delete argument to exchange_declare deprecated
  • insist argument to Connection removed.
  • Channel.alerts has been removed.
  • Support for Channel.basic_recover_async.
  • Channel.basic_recover deprecated.

• Exceptions renamed to have idiomatic names:

  • AMQPException -> AMQPError
  • AMQPConnectionException -> ConnectionError``
  • AMQPChannelException -> ChannelError``
  • Connection.known_hosts removed.
  • Connection no longer supports redirects.
  • exchange argument to queue_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
