- Dropped python 3.4

- Bump py-amqp to 2.5.0

- Use SIMEMBERS instead of SMEMBERS to check for queue (redis broker)

* Add `_lookup_direct` method to virtual channel. (994)

Add possibility to optimize lookup for queue in direct
exchange set.

* Add `_lookup_direct` method to redis virtual channel. (994)

Use `SISMEMBER` instead of `SMEMBERS` command to check if queue
exists in a set. Time complexity is increased from O(N) to O(1)
where N is the set cardinality.

- Include priority in properties only if it's not None.
Since we attempt to serialize the priority property if it exists
in the dictionary it must be an integer.

.. _version-4.5.0:

=====
:release-date: 2019-03-3 18:30 P.M UTC+3:00
:release-by: Omer Katz

- The Redis transport now supports a custom separator for keys.

Previously when storing a key in Redis which represents a queue
we used the hardcored value ``\x06\x16`` separator to store
different attributes of the queue in the queue's name.

The separator is now configurable using the sep
transport option:

.. code-block:: python

 with Connection('redis://', transport_options={
         'sep': ':',
     }):
      ...
     pass

Contributed by **Joris Beckers**

- When the SQS server returns a timeout we ignore it and keep trying
instead of raising an error.

This will prevent Celery from raising an error and hanging.

Contributed by **Erwin Rossen**

- Properly declare async support for the Qpid transport.

If you are using this transport we strongly urge you to upgrade.

Contributed by **Rohan McGovern**

- Revert `celery/kombu906 <https://github.com/celery/kombu/pull/906>`_ and
introduce unique broadcast queue names as an optional keyword argument.

If you want each broadcast queue to have a unique name specify `unique=True`:

.. code-block:: pycon

 >>> from kombu.common import Broadcast
 >>> q = Broadcast(queue='foo', unique=True)
 >>> q.name
 'foo.7ee1ac20-cda3-4966-aaf8-e7a3bb548688'
 >>> q = Broadcast(queue='foo')
 >>> q.name
 'foo'

:release-date: 2019-03-3 9:00 P.M UTC+2:00
:release-by: Omer Katz

- Restore bz2 import checks in compression module.

The checks were removed in `celery/kombu938 <https://github.com/celery/kombu/pull/938>`_ due to assumption that it only affected Jython.
However, bz2 support can be missing in Pythons built without bz2 support.

when parsing  Redis Sentinel master URI containing password.

Contributed by **Paul Bailey**

- Revert `celery/kombu954 <https://github.com/celery/kombu/pull/954>`_.
Instead bump the required redis-py dependency to 3.2.0
to include this fix `andymccurdy/redis-py4e1e748 <https://github.com/andymccurdy/redis-py/commit/4e1e74809235edc19e03edb79c97c80a3e4e9eca>`_.

- Avoid caching queues which are declared with a TTL.

Queues that are declared with a TTL are now also be excluded from the
in-memory cache in case they expire between publishes on the same channel.

Contributed by **Matt Yule-Bennett**

- Added an index to the Message table for the SQLAlchemy transport.

The index allows to effectively sorting the table by the message's timestamp.

.. note::

 We do not provide migrations for this model yet.
 You will need to add the index manually if you are already
 using the SQLAlchemy transport.

 The syntax may vary between databases.
 Please refer to your database's documentation for instructions.

- Added a timeout that limits the amount of time we retry
to reconnect to a transport.

Contributed by **:github_user:`tothegump`**

- :class:``celery.asynchronous.hub.Hub`` is now reentrant.

This allows calling :func:`celery.bin.celery.main` to revive a worker in
the same process after rescuing from shutdown (:class:``SystemExit``).

Contributed by **Alan Justino da Silva**

- Queues now accept string exchange names as arguments as documented.

Tests were added to avoid further regressions.

Contributed by **Antonio Gutierrez**

- Specifying names for broadcast queues now work as expected.

Previously, named broadcast queues did not create multiple queues per worker.
They incorrectly declared the named queue which resulted in one queue per
fanout exchange, thus missing the entire point of a fanout exchange.
The behavior is now matched to unnamed broadcast queues.

Contributed by **Kuan Hsuan-Tso**

- When initializing the Redis transport in conjunction with gevent
restore all unacknowledged messages to queue.

Contributed by **Gal Cohen**

- Allow :class:``kombu.simple.SimpleQueue`` to pass queue_arguments to Queue object.

This allows :class:``kombu.simple.SimpleQueue`` to connect to RabbitMQ queues with
custom arguments like 'x-queue-mode'='lazy'.

Contributed by **C Blue Neeh**

- Add support for 'rediss' scheme for secure Redis connections.

The rediss scheme defaults to the least secure form, as
there is no suitable default location for `ca_certs`. The recommendation
would still be to follow the documentation and specify `broker_use_ssl` if
coming from celery.

Contributed by **Daniel Blair**

- Added the Azure Storage Queues transport.

The transport is implemented on top of Azure Storage
Queues. This offers a simple but scalable and low-cost PaaS
transport for Celery users in Azure. The transport is intended to be
used in conjunction with the Azure Block Blob Storage backend.

**Denis Kisselev**, **Evandro de Paula**, **Martin Peck**
and **:github_user:`michaelperel`**

- Added the Azure Service Bus transport.

The transport is implemented on top of Azure Service Bus and
offers PaaS support for more demanding Celery workloads in Azure.
The transport is intended to be used in conjunction with the Azure
CosmosDB backend.

Contributed by **Alexey Popravka**

- the `Pyro`_ transport (:mod:`kombu.transport.pyro`) now works with
recent Pyro versions. Also added a Pyro Kombu Broker that this transport
needs for its queues.

Contributed by **Irmen de Jong**

- Handle non-base64-encoded SQS messages.

Fix contributed by **Tim Li**, **Asif Saif Uddin** and **Omer Katz**.

- Move the handling of Sentinel failures to the redis library itself.

Previously, Redis Sentinel worked only if the first node's sentinel
service in the URI was up. A server outage would have caused downtime.

Contributed by **Brian Price**

- When using Celery and the pickle serializer with binary data as part of the
payload, `UnicodeDecodeError` would be raised as the content was not utf-8.
We now replace on errors.

Contributed by **Jian Dai**

- Allow setting :method:``boto3.sqs.create_queue`` Attributes via transport_options.

Contributed by **Hunter Fernandes**

- Fixed infinite loop when entity.channel is replaced by revive() on connection
drop.

- Added optional support for Brotli compression.

Contributed by **Omer Katz**

- When using the SQS broker, FIFO queues with names that ended with the 'f' letter
were incorrectly parsed. This is now fixed.

Contributed by **Alex Vishnya** and **Ilya Konstantinov**

-  Added optional support for LZMA compression.

Contributed by **Omer Katz**

- Added optional support for ZStandard compression.

- The value of DISABLE_TRACEBACKS environment variable is now respected on debug, info
and warning logger level.

Contributed by **Ludovic Rivallain**

- As documented in kombu/741 and eventlet/eventlet415
there is a mismatch between the monkey-patched eventlet queue
and the interface Kombu is expecting.
This causes Celery to crash when the `broker_pool_limit`
configuration option is set
eventlet/eventlet415 suggests that the mutex can be a noop.
This is now the case.
