.. _version-4.0:
4.0
===
:release-date: TBA
- Now depends on :mod:`amqp` 2.0.0.
- No longer depends on :mod:`anyjson`.
- New SQS transport
Donated by NextDoor, with additional contributions from mdk.
- Redis: Priority 0 is now lowest, 9 is highest.
(**backward incompatible**)
This to match how priorities in AMQP works.
Fix contributed by Alex Koshelev.
- Beanstalk: Priority 0 is now lowest, 9 is highest.
(**backward incompatible**)
This to match how priorities in AMQP works.
Fix contributed by Alex Koshelev.
- Redis: now supports SSL using the ``ssl`` argument to
:class:`~kombu.Connection`.
- Redis: Fanout exchanges are no longer visible between vhosts,
and fanout messages can be filtered by patterns.
(**backward incompatible**)
It was possible to enable this mode previously using the
``fanout_prefix``, and ``fanout_patterns``
transport options, but now these are enabled by default.
If you want to mix and match producers/consumers running different
versions you need to configure your kombu 3.x clients to also enable
these options:
.. code-block:: pycon
>>> Connection(transport_options={
'fanout_prefix': True,
'fanout_patterns': True,
})
- Exchange.delivery_mode now defaults to :const:`None`, and the default
is instead set by ``Producer.publish``.
- :class:`~kombu.Consumer` now supports a new ``prefetch_count`` argument,
which if provided will force the consumer to set an initial prefetch count
just before starting.
- Virtual transports now stores ``priority`` as a property, not in
``delivery_info``, to be compatible with AMQP.
- ``reply_to`` argument to ``Producer.publish`` can now be
:class:`~kombu.Queue` instance.
- Connection: There's now a new method
``Connection.supports_exchange_type(type)`` that can be used to check if the
current transport supports a specific exchange type.
- SQS: Consumers can now read json messages not sent by Kombu.
Contributed by Juan Carlos Ferrer.
- SQS: Will now log the access key used when authentication fails.
Contributed by Hank John.
- Added new :class:`kombu.mixins.ConsumerProducerMixin` for consumers that
will also publish messages on a separate connection.
- Messages: Now have a more descriptive ``repr``.
Contributed by Joshua Harlow.
- Async: HTTP client based on curl.
- Async: Now uses `poll` instead of `select` where available.
- MongoDB: Now supports priorities
Contributed by Alex Koshelev.
- Zookeeper: Transport now uses the built-in suport in kazoo to handle
failover when using a list of server names.
Contributed by Joshua Harlow.

.. admonition:: Django transport migrations.
If you're using Django 1.8 and have already created the
kombu_transport_django tables, you have to run a fake initial migration:
.. code-block:: console
$ python manage.py migrate kombu_transport_django --fake-initial
- No longer compatible with South by default.
To keep using kombu.transport.django with South migrations
you now need to configure a new location for the kombu migrations:
.. code-block:: python
SOUTH_MIGRATION_MODULES = {
'kombu_transport_django':
'kombu.transport.django.south_migrations',
}
- Keep old South migrations in ``kombu.transport.django.south_migrations``.

- 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`.

:release-date: 2014-03-03 04:00 P.M UTC
:release-by: Ask Solem
- Redis: Fixed serious race condition that could lead to data loss.
The delivery tags were accidentally set to be an incremental number
local to the channel, but the delivery tags need to be globally
unique so that a message can not overwrite an older message
in the backup store.
This change is not backwards incompatible and you are encouraged
to update all your system using a previous version as soon as possible.
- Now depends on :mod:`amqp` 1.4.4.
- Pidbox: Now makes sure message encoding errors are handled by default,
so that a custom error handler does not need to be specified.
- Redis: The fanout exchange can now use AMQP patterns to route and filter
messages.
This change is backwards incompatible and must be enabled with
the ``fanout_patterns`` transport option:
.. code-block:: pycon
>>> conn = kombu.Connection('redis://', transport_options={
... 'fanout_patterns': True,
... })
When enabled the exchange will work like an amqp topic exchange
if the binding key is a pattern.
This is planned to be default behavior in the future.
- Redis: Fixed ``cycle`` no such attribute error.

- Now depends on :mod:`amqp` 1.4.2.
- Now always trusts messages of type `application/data` and `application/text`
or which have an unspecified content type (Issue #306).
- Compression errors are now handled as decode errors and will trigger
the ``Consumer.on_decode_error`` callback if specified.
- New ``kombu.Connection.get_heartbeat_interval()`` method that can be
used to access the negotiated heartbeat value.
- `kombu.common.oid_for` no longer uses the MAC address of the host, but
instead uses a process-wide UUID4 as a node id.
This avoids a call to `uuid.getnode()` at module scope.
- Hub.add: Now normalizes registered fileno.

- Now depends on :mod:`amqp` 1.4.1.
- ``maybe_declare`` now raises a "recoverable connection error" if
the channel is disconnected instead of a :exc:`ChannelError` so that
the operation can be retried.
- Redis: ``Consumer.cancel()`` is now thread safe.
This fixes an issue when using gevent/eventlet and a
message is handled after the consumer is canceled resulting
in a "message for queue without consumers" error.
- Retry operations would not always respect the interval_start
value when calculating the time to sleep for (Issue #303).

- Now depends on :mod:`amqp` 1.4.0.
- Redis: Basic cancel for fanout based queues now sends a corresponding
``UNSUBSCRIBE`` command to the server.
This fixes an issue with pidbox where reply messages could be received
after the consumer was canceled, giving the ``"message to queue without
consumers"`` error.
- MongoDB: Improved connection string and options handling
(Issue #266 + Issue #120).
Contributed by Alex Koshelev.
- SQS: Limit the number of messages when receiving in batch to 10.
This is a hard limit enforced by Amazon so the sqs transport
must not exceeed this value.

- ConsumerMixin: ``consume`` now checks heartbeat every time the
socket times out.

- Now depends on :mod:`amqp` version 1.3.1.
- Redis: New option ``fanout_keyprefix``
This transport option is recommended for all users as it ensures
that broadcast (fanout) messages sent is only seen by the current
virtual host:
.. code-block:: python
Connection('redis://', transport_options={'fanout_keyprefix': True})
However, enabling this means that you cannot send or receive messages
from older Kombu versions so make sure all of your participants
are upgraded and have the transport option enabled.
This will be the default behavior in Kombu 4.0.
- Distribution: Removed file ``requirements/py25.txt``.
