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
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 to basic_consume.
- 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).
- Authentication Failure Notifications
  
  Instead of just closing the connection abruptly on invalid credentials, py-amqp will raise an AccessRefused error when connected to rabbitmq-server 3.2.0 or greater.
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

Quick overview

Simple producer publishing messages to test queue using default exchange:

import amqp

with amqp.Connection('broker.example.com') as c:
    ch = c.channel()
    ch.basic_publish(amqp.Message('Hello World'), routing_key='test')

Producer publishing to test_exchange exchange with publisher confirms enabled and using virtual_host test_vhost:

import amqp

with amqp.Connection(
    'broker.example.com', exchange='test_exchange',
    confirm_publish=True, virtual_host='test_vhost'
) as c:
    ch = c.channel()
    ch.basic_publish(amqp.Message('Hello World'), routing_key='test')

Consumer with acknowledgments enabled:

import amqp

with amqp.Connection('broker.example.com') as c:
    ch = c.channel()
    def on_message(message):
        print('Received message (delivery tag: {}): {}'.format(message.delivery_tag, message.body))
        ch.basic_ack(message.delivery_tag)
    ch.basic_consume(queue='test', callback=on_message)
    while True:
        c.drain_events()

Consumer with acknowledgments disabled:

import amqp

with amqp.Connection('broker.example.com') as c:
    ch = c.channel()
    def on_message(message):
        print('Received message (delivery tag: {}): {}'.format(message.delivery_tag, message.body))
    ch.basic_consume(queue='test', callback=on_message, no_ack=True)
    while True:
        c.drain_events()

Speedups

This library has experimental support of speedups. Speedups are implemented using Cython. To enable speedups, CELERY_ENABLE_SPEEDUPS environment variable must be set during building/installation. Currently speedups can be installed:

using source package (using --no-binary switch):

CELERY_ENABLE_SPEEDUPS=true pip install --no-binary :all: amqp

building directly source code:

CELERY_ENABLE_SPEEDUPS=true python setup.py install
