4.0.2

===== :release-date: 2016-12-15 03:40 PM PST :release-by: Ask Solem

• Requirements

  • Now depends on :ref:Kombu 4.0.2 <kombu:version-4.0.2>.

• Tasks: Fixed problem with JSON serialization of group (keys must be string error, Issue 3688).

• Worker: Fixed JSON serialization issue when using inspect active and friends (Issue 3667).

• App: Fixed saferef errors when using signals (Issue 3670).

• Prefork: Fixed bug with pack requiring bytes argument on Python 2.7.5 and earlier (Issue 3674).

• Tasks: Saferepr did not handle unicode in bytestrings on Python 2 (Issue 3676).

• Testing: Added new celery_worker_paremeters fixture.

  Contributed by Michael Howitz.

• Tasks: Added new app argument to GroupResult.restore (Issue 3669).

  This makes the restore method behave the same way as the GroupResult constructor.

  Contributed by Andreas Pelme.

• Tasks: Fixed type checking crash when task takes *args on Python 3 (Issue 3678).

• Documentation and examples improvements by:

  • BLAGA Razvan-Paul

4.0.1

===== :release-date: 2016-12-08 05:22 PM PST :release-by: Ask Solem

• [Security: CELERYSA-0003_] Insecure default configuration

  The default :setting:accept_content setting was set to allow deserialization of pickled messages in Celery 4.0.0.

  The insecure default has been fixed in 4.0.1, and you can also configure the 4.0.0 version to explicitly only allow json serialized messages:

  .. code-block:: python

  app.conf.accept_content = ['json']

.. _CELERYSA-0003: https://github.com/celery/celery/tree/master/docs/sec/CELERYSA-0003.txt

• Tasks: Added new method to register class-based tasks (Issue 3615).

  To register a class based task you should now call app.register_task:

  .. code-block:: python

  from celery import Celery, Task

  app = Celery()

  class CustomTask(Task):

     def run(self):
         return 'hello'

  app.register_task(CustomTask())

• Tasks: Argument checking now supports keyword-only arguments on Python3 (Issue 3658).

  Contributed by :github_user:sww.

• Tasks: The task-sent event was not being sent even if configured to do so (Issue 3646).

• Worker: Fixed AMQP heartbeat support for eventlet/gevent pools (Issue 3649).

• App: app.conf.humanize() would not work if configuration not finalized (Issue 3652).

• Utils: saferepr attempted to show iterables as lists and mappings as dicts.

• Utils: saferepr did not handle unicode-errors when attempting to format bytes on Python 3 (Issue 3610).

• Utils: saferepr should now properly represent byte strings with non-ascii characters (Issue 3600).

• Results: Fixed bug in elasticsearch where _index method missed the body argument (Issue 3606).

  Fix contributed by 何翔宇 (Sean Ho).

• Canvas: Fixed :exc:ValueError in chord with single task header (Issue 3608).

  Fix contributed by Viktor Holmqvist.

• Task: Ensure class-based task has name prior to registration (Issue 3616).

  Fix contributed by Rick Wargo.

• Beat: Fixed problem with strings in shelve (Issue 3644).

  Fix contributed by Alli.

• Worker: Fixed :exc:KeyError in inspect stats when -O argument set to something other than fast or fair (Issue 3621).

• Task: Retried tasks were no longer sent to the original queue (Issue 3622).

• Worker: Python 3: Fixed None/int type comparison in :file:apps/worker.py (Issue 3631).

• Results: Redis has a new :setting:redis_socket_connect_timeout setting.

• Results: Redis result backend passed the socket_connect_timeout argument to UNIX socket based connections by mistake, causing a crash.

• Worker: Fixed missing logo in worker splash screen when running on Python 3.x (Issue 3627).

  Fix contributed by Brian Luan.

• Deps: Fixed celery[redis] bundle installation (Issue 3643).

  Fix contributed by Rémi Marenco.

• Deps: Bundle celery[sqs] now also requires :pypi:pycurl (Issue 3619).

• Worker: Hard time limits were no longer being respected (Issue 3618).

• Worker: Soft time limit log showed Trues instead of the number of seconds.

• App: registry_cls argument no longer had any effect (Issue 3613).

• Worker: Event producer now uses connection_for_Write (Issue 3525).

• Results: Redis/memcache backends now uses :setting:result_expires to expire chord counter (Issue 3573).

  Contributed by Tayfun Sen.

• Django: Fixed command for upgrading settings with Django (Issue 3563).

  Fix contributed by François Voron.

• Testing: Added a celery_parameters test fixture to be able to use customized Celery init parameters. (3626)

Important notes

• Database result backend related setting names changed from sqlalchemy_* -> database_*.

  The sqlalchemy_ named settings won't work at all in this version so you need to rename them. This is a last minute change, and as they were not supported in 3.1 we will not be providing aliases.

• chain(A, B, C) now works the same way as A | B | C.

  This means calling chain() might not actually return a chain, it can return a group or any other type depending on how the workflow can be optimized.
