  • Remove dependency to case

  • Bugfix: not closing socket after server disconnect

5.0.6

release-date

2021-04-01 10:45 A.M. UTC+6:00

release-by

Asif Saif Uddin

  • Change the order in which context.check_hostname and context.verify_mode get set in SSLTransport._wrap_socket_sni. Fixes bug introduced in 5.0.3 where setting context.verify_mode = ssl.CERT_NONE would raise “ValueError: Cannot set verify_mode to CERT_NONE when check_hostname is enabled.” Setting context.check_hostname prior to setting context.verify_mode resolves the issue.

  • Remove TCP_USER_TIMEOUT option for Solaris (#355)

  • Pass long_description to setup() (#353)

  • Fix for tox-docker 2.0

  • Moved to GitHub actions CI (#359)

5.0.5

release-date

2021-01-28 4:30 P.M UTC+6:00

release-by

Asif Saif Uddin

  • Removed mistakenly introduced code which was causing import errors

5.0.4

release-date

2021-01-28 2:30 P.M UTC+6:00

release-by

Asif Saif Uddin

  • Add missing load_default_certs() call to fix a regression in v5.0.3 release. (#350)

5.0.3

release-date

2021-01-19 9:00 P.M UTC+6:00

release-by

Asif Saif Uddin

  • Change the default value of ssl_version to None. When not set, the proper value between ssl.PROTOCOL_TLS_CLIENT and ssl.PROTOCOL_TLS_SERVER will be selected based on the param server_side in order to create a TLS Context object with better defaults that fit the desired connection side.

  • Change the default value of cert_reqs to None. The default value of ctx.verify_mode is ssl.CERT_NONE, but when ssl.PROTOCOL_TLS_CLIENT is used, ctx.verify_mode defaults to ssl.CERT_REQUIRED.

  • Fix context.check_hostname logic. Checking the hostname depends on having support of the SNI TLS extension and being provided with a server_hostname value. Another important thing to mention is that enabling hostname checking automatically sets verify_mode from ssl.CERT_NONE to ssl.CERT_REQUIRED in the stdlib ssl and it cannot be set back to ssl.CERT_NONE as long as hostname checking is enabled.

  • Refactor the SNI tests to test one thing at a time and removing some tests that were being repeated over and over.

5.0.2

release-by

Asif Saif Uddin

  • Fix buffer overflow in frame_writer after frame_max is increased. frame_writer

allocates a bytearray on initialization with a length based on the connection.frame_max value. If connection.frame_max is changed to a larger value, this causes an error like pack_into requires a buffer of at least 408736 bytes.

2.4.0

release-date

2018-13-01 1:00 P.M UTC+2

release-by

Omer Katz

  • Fix inconsistent frame_handler return value.

    The function returned by frame_handler is meant to return True once the complete message is received and the callback is called, False otherwise.

    This fixes the return value for messages with a body split across multiple frames, and heartbeat frames.

    Fix contributed by :github_user:`evanunderscore`

  • Don’t default content_encoding to utf-8 for bytes.

    This is not an acceptable default as the content may not be valid utf-8, and even if it is, the producer likely does not expect the message to be decoded by the consumer.

    Fix contributed by :github_user:`evanunderscore`

  • Fix encoding of messages with multibyte characters.

    Body length was previously calculated using string length, which may be less than the length of the encoded body when it contains multibyte sequences. This caused the body of the frame to be truncated.

    Fix contributed by :github_user:`evanunderscore`

  • Respect content_encoding when encoding messages.

    Previously the content_encoding was ignored and messages were always encoded as utf-8. This caused messages to be incorrectly decoded if content_encoding is properly respected when decoding.

    Fix contributed by :github_user:`evanunderscore`

  • Fix AMQP protocol header for AMQP 0-9-1.

    Previously it was set to a different value for unknown reasons.

    Fix contributed by Carl Hörberg

  • Add support for Python 3.7.

    Change direct SSLSocket instantiation with wrap_socket. Added Python 3.7 to CI.

    Fix contributed by Omer Katz and :github_user:`avborhanian`

  • Add support for field type “x” (byte array).

    Fix contributed by Davis Kirkendall

  • If there is an exception raised on Connection.connect or Connection.close, ensure that the underlying transport socket is closed.

    Adjust exception message on connection errors as well.

    Fix contributed by :github_user:`tomc797`

  • TCP_USER_TIMEOUT has to be excluded from KNOWN_TCP_OPTS in BSD platforms.

    Fix contributed by George Tantiras

  • Handle negative acknowledgments.

    Fix contributed by Matus Valo

  • Added integration tests.

    Fix contributed by Matus Valo

  • Fix basic_consume() with no consumer_tag provided.

    Fix contributed by Matus Valo

  • Improved empty AMQPError string representation.

    Fix contributed by Matus Valo

  • Drain events before publish.

    This is needed to capture out of memory messages for clients that only publish. Otherwise on_blocked is never called.

    Fix contributed by Jelte Fennema and Matus Valo

  • Don’t revive channel when connection is closing.

    When connection is closing don’t raise error when Channel.Close method is received.

    Fix contributed by Matus Valo

  • Fix a regression that occurs when running amqp under Python 2.7.

    #182 mistakenly replaced a type check with unicode to string_t which is str in Python 2.7. text_t should have been used instead. This is now fixed and the tests have been adjusted to ensure this never regresses again.

  • Removes byte string comparison warnings when running under python -b.

    Fix contributed by Jon Dufresne.

  • Linux version parsing broke when the version included a ‘+’ character (Issue #119).

  • Now sets default TCP settings for platforms that support them (e.g. Linux).

    Constant

    TCP_KEEPINTVL

    10

    TCP_KEEPCNT

    9

    TCP_USER_TIMEOUT

    1000 (1s)

    This will help detecting the socket being closed earlier, which is very important in failover and load balancing scenarios.

2.1.3

release-date

2016-12-07 06:00 P.M PST

release-by

Ask Solem

  • Fixes compatibility with Python 2.7.5 and below (Issue #107).

2.1.2

release-date

2016-12-07 02:00 P.M PST

  • Linux: Now sets the TCP_USER_TIMEOUT flag if available for better failed connection detection.

    Contributed by Jelte Fennema.

    The timeout is set to the connect_timeout value by default, but can also be specified by using the socket_settings argument to Connection:

    from amqp import Connection
    from amqp.platform import TCP_USER_TIMEOUT
    
    conn = Connection(socket_settings={
        TCP_USER_TIMEOUT: int(60 * 1000),  # six minutes in ms.
    })
    

    When using Kombu this can be specified as part of the transport_options:

    from amqp.platform import TCP_USER_TIMEOUT
    from kombu import Connection
    
    conn = Connection(transport_options={
        'socket_settings': {
            TCP_USER_TIMEOUT: int(60 * 1000),  # six minutes in ms.
        },
    })
    

    Or when using Celery it can be specified using the broker_transport_options setting:

    from amqp.platform import TCP_USER_TIMEOUT
    from celery import Celery
    
    app = Celery()
    app.conf.update(
        broker_transport_options={
            TCP_USER_TIMEOUT: int(60 * 1000),  # six minutes in ms.
        }
    )
    
  • Python compatibility: Fixed compatibility when using the python -b flag.

    Fix contributed by Jon Dufresne.

  • Requirements

    • Now depends on Vine 1.1.3.

  • Frame writer: Account for overhead when calculating frame size.

    The client would crash if the message was within a certain size.

  • Fixed struct unicode problems (#108)

    • Standardize pack invocations on bytestrings.

    • Leave some literals as strings to enable interpolation.

    • Fix flake8 fail.

Ask Solem

  • Requirements

    • Now depends on Vine 1.1.2.

  • Now licensed under the BSD license!

    Thanks to Barry Pederson for approving the license change, which unifies the license used across all projects in the Celery organization.

  • Datetimes in method frame arguments are now handled properly.

  • Fixed compatibility with Python <= 2.7.6

  • Frame_writer is no longer a generator, which should solve a rare “generator already executing” error (Issue #103).

2.0.3

release-date

2016-07-11 08:00 P.M PDT

release-by

Ask Solem

  • SSLTransport: Fixed crash “no attribute sslopts” when ssl=True (Issue #100).

  • Fixed incompatible argument spec for Connection.Close (Issue #45).

    This caused the RabbitMQ server to raise an exception (INTERNAL ERROR).

  • Transport: No longer implements __del__ to make sure gc can collect connections.

    It’s the responsibility of the caller to close connections, this was simply a relic from the amqplib library.

    Fix contributed by Bas ten Berge.

  • Fixed compatibility with Python 2.7.3 (Issue #85)

    Fix contributed by Bas ten Berge.

  • Fixed bug where calling drain_events() with a timeout of 0 would actually block until a frame is received.

  • Documentation moved to http://amqp.readthedocs.io (Issue #89).

    See https://blog.readthedocs.com/securing-subdomains/ for the reasoning behind this change.

  • No longer supports Python 2.6

  • You must now call Connection.connect() to establish the connection.

    The Connection constructor no longer has side effects, so you have to explicitly call connect first.

  • Library rewritten to anticipate async changes.

  • Connection now exposes underlying socket options.

    This change allows to set arbitrary TCP socket options during the creation of the transport.

    Those values can be set passing a dictionray where the key is the name of the parameter we want to set. The names of the keys are the ones reported above.

release-date

2014-01-13 03:00 P.M UTC

release-by

Ask Solem

  • Heartbeat implementation improved (Issue #6).

    The new heartbeat behavior is the same approach as taken by the RabbitMQ java library.

    This also means that clients should preferably call the heartbeat_tick method more frequently (like every second) instead of using the old rate argument (which is now ignored).

    • Heartbeat interval is negotiated with the server.

    • Some delay is allowed if the heartbeat is late.

    • Monotonic time is used to keep track of the heartbeat instead of relying on the caller to call the checking function at the right time.

    Contributed by Dustin J. Mitchell.

  • NoneType is now supported in tables and arrays.

    amqplib used to make the channel object available as Message.delivery_info['channel'], but this was removed in py-amqp. librabbitmq sets Message.channel, which is a more reasonable solution in our opinion as that keeps the delivery info intact.

  • New option to wait for publish confirmations (Issue #3)

    There is now a new Connection confirm_publish that will force any basic_publish call to wait for confirmation.

    Enabling publisher confirms like this degrades performance considerably, but can be suitable for some applications and now it’s possible by configuration.

  • queue_declare now returns named tuple of type basic_declare_ok_t.

    Supporting fields: queue, message_count, and consumer_count.

  • Contents of Channel.returned_messages is now named tuples.

    Supporting fields: reply_code, reply_text, exchange, routing_key, and message.

  • Sockets now set to close on exec using the FD_CLOEXEC flag.

    Currently only supported on platforms supporting this flag, which does not include Windows.

    • 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).

    • 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
