kombu v3.0.15 Release Notes

  • 🚀 :release-date: 2014-04-15 09:00 P.M UTC 🚀 :release-by: Ask Solem

    • Now depends on :mod:amqp 1.4.5.

    • RabbitMQ 3.3 changes QoS semantics (Issue #339).

      See the RabbitMQ release notes here: http://www.rabbitmq.com/blog/2014/04/02/breaking-things-with-rabbitmq-3-3/

      A new connection property has been added that can be used to detect whether the remote server is using this new QoS behavior:

      .. code-block:: pycon

      >>> Connection('amqp://').qos_behavior_matches_spec
False

      so if your application depends on the old semantics you can use this to set the apply_global flag appropriately:

      .. code-block:: python

      def update_prefetch_count(channel, new_value):
    channel.basic_qos(
        0, new_value,
        not channel.connection.client.qos_behavior_matches_spec,
    )

    • ⬆️ Users of :mod:librabbitmq is encouraged to upgrade to librabbitmq 1.5.0.

      The kombu[librabbitmq] extra has been updated to depend on this version.

    • Pools: Now takes transport options into account when comparing connections (Issue #333).

    • 🛠 MongoDB: Fixes Python 3 compatibility.

    • Async: select: Ignore socket errors when attempting to unregister handles from the loop.

    • 🔧 Pidbox: Can now be configured to use a serializer other than json, but specifying a serializer argument to :class:~kombu.pidbox.Mailbox.

    • Message decompression now works with Python 3.

      Fix contributed by Adam Gaca.
