- [Redis] New and improved fair queue cycle algorithm (Kevin McCarthy).
- [Redis] Now uses a Redis-based mutex when restoring messages.
- [Redis] Number of messages that can be restored in one interval is no
longer limited (but can be set using the
unacked_restore_limit
transport option <BROKER_TRANSPORT_OPTIONS>.)
- Heartbeat value can be specified in broker URLs (Mher Movsisyan).
- Fixed problem with msgpack on Python 3 (Jasper Bryant-Greene).
- Now depends on billiard 2.7.3.18
- Celery can now be used with static analysis tools like PyDev/PyCharm/pylint
etc.

The new URL is: http://docs.celeryproject.org/en/master
- New CELERY_QUEUE_HA_POLICY setting used to set the default
HA policy for queues when using RabbitMQ.
New method Task.subtask_from_request returns a subtask using the current
request.
- Results get_many method did not respect timeout argument.

- generic_init.d scripts now support setting CELERY_CREATE_DIRS to
always create log and pid directories (Issue #1045).
This can be set in your /etc/default/celeryd.

- generic-init.d scripts changed permissions of /var/log & /var/run
In the daemonization tutorial the recommended directories were as follows:
CELERYD_LOG_FILE="/var/log/celery/%n.log"
CELERYD_PID_FILE="/var/run/celery/%n.pid"
But in the scripts themselves the default files were /var/log/celery%n.log
and /var/run/celery%n.pid, so if the user did not change the location
by configuration, the directories /var/log and /var/run would be
created - and worse have their permissions and owners changed.
This change means that:
- Default pid file is /var/run/celery/%n.pid
- Default log file is /var/log/celery/%n.log
- The directories are only created and have their permissions
changed if *no custom locations are set*.
Users can force paths to be created by calling the create-paths
subcommand:
$ sudo /etc/init.d/celeryd create-paths
Upgrading Celery will not update init scripts
To update the init scripts you have to re-download
the files from source control and update them manually.
You can find the init scripts for version 3.0.x at:

- Now depends on billiard 2.7.3.17
- Fixes request stack protection when app is initialized more than
once (Issue #1003).
- ETA tasks now properly works when system timezone is not the same
as the configured timezone (Issue #1004).
- Terminating a task now works if the task has been sent to the
pool but not yet acknowledged by a pool process (Issue #1007).

- Now depends on kombu 2.4.7
- Now depends on billiard 2.7.3.14
- Fixes crash at startup when using Django and pre-1.4 projects
(setup_environ).
- Hard time limits now sends the KILL signal shortly after TERM,
to terminate processes that have signal handlers blocked by C extensions.
- Billiard now installs even if the C extension cannot be built.
It's still recommended to build the C extension if you are using
a transport other than rabbitmq/redis (or use forced execv for some
other reason).
- Pool now sets a ``current_process().index`` attribute that can be used to create
as many log files as there are processes in the pool.
- Canvas: chord/group/chain no longer modifies the state when called
Previously calling a chord/group/chain would modify the ids of subtasks
so that:
>>> c = chord([add.s(2, 2), add.s(4, 4)], xsum.s())
>>> c()
>>> c() <-- call again
at the second time the ids for the tasks would be the same as in the
previous invocation. This is now fixed, so that calling a subtask
won't mutate any options.
- Canvas: Chaining a chord to another task now works (Issue #965).
- Worker: Fixed a bug where the request stack could be corrupted if
relative imports are used.
Problem usually manifested itself as an exception while trying to
send a failed task result (NoneType does not have id attribute).
Fix contributed by Sam Cooke.
- Tasks can now raise celery.exceptions.Ignore to skip updating states
or events after return.
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python/python-celery?expand=0&rev=70
- Important note for users of Django and the database scheduler!
Recently a timezone issue has been fixed for periodic tasks,
but erroneous timezones could have already been stored in the
database, so for the fix to work you need to reset
the last_run_at fields.
You can do this by executing the following command:
$ python manage.py shell
>>> from djcelery.models import PeriodicTask
>>> PeriodicTask.objects.update(last_run_at=None)
You also have to do this if you change the timezone or
CELERY_ENABLE_UTC setting.
- Note about the CELERY_ENABLE_UTC setting.
If you previously disabled this just to force periodic tasks to work with
your timezone, then you are now *encouraged to re-enable it*.
- Now depends on Kombu 2.4.5 which fixes PyPy + Jython installation.
- Fixed bug with timezones when :setting:`CELERY_ENABLE_UTC` is disabled
(Issue #952).
- Fixed a typo in the celerybeat upgrade mechanism (Issue #951).
- Make sure the exc_info argument to logging is resolved (Issue #899).
- Fixed problem with Python 3.2 and thread join timeout overflow (Issue #796).
- A test case was occasionally broken for Python 2.5.
- Unit test suite now passes for PyPy 1.9.
- App instances now supports the with statement.
This calls the new :meth:`~celery.Celery.close` method at exit, which
cleans up after the app like closing pool connections.
Note that this is only necessary when dynamically creating apps,
e.g. for "temporary" apps.
- Support for piping a subtask to a chain.
For example:

- Beat: Fixed another timezone bug with interval and crontab schedules
(Issue #943).
- Beat: The schedule file is now automatically cleared if the timezone
is changed.
The schedule is also cleared when you upgrade to 3.0.8 from an earlier
version, this to register the initial timezone info.
- Events: The worker-heartbeat event now include processed and active
count fields.

- Fixed error with error email and new task classes (Issue #931).
- BaseTask.__call__ is no longer optimized away if it has been monkey
patched.
- Fixed shutdown issue when using gevent (Issue #911 & Issue #936).

- Now depends on kombu 2.4.2
- Redis: Fixes a race condition crash
- Fixes an infinite loop that could happen when retrying establishing
the broker connection.
- Daemons now redirect standard file descriptors to /dev/null
Though by default the standard outs are also redirected
to the logger instead, but you can disable this by changing
the CELERY_REDIRECT_STDOUTS setting.
- Fixes possible problems when eventlet/gevent is patched too late.
- LoggingProxy no longer defines fileno() (Issue #928).
- Results are now ignored for the chord unlock task.

- Celery command: Extensions are now sorted by name.
- A regression caused the task-failed event to be sent
with the exception object instead of its string representation.
- The worker daemon would try to create the pid file before daemonizing
to catch errors, but this file was not immediately released (Issue #923).
- Fixes Jython compatibility.
- billiard.forking_enable was called by all pools not just the
processes pool, which would result in a useless warning if the billiard
C extensions were not installed.

- Now depends on kombu 2.4.0
- Now depends on billiard 2.7.3.12
- Redis: Celery now tries to restore messages whenever there are no messages
in the queue.
- Crontab schedules now properly respects CELERY_TIMEZONE setting.
It's important to note that crontab schedules uses UTC time by default
unless this setting is set.
Issue #904 and django-celery #150.
- billiard.enable_forking is now only set by the processes pool.
- The transport is now properly shown by celery report
(Issue #913).
- The --app argument now works if the last part is a module name
(Issue #921).
- Fixed problem with unpickleable exceptions (billiard #12).
- Adds task_name attribute to EagerResult which is always
None (Issue #907).
- Old Task class in celery.task no longer accepts magic kwargs by
default (Issue #918).
A regression long ago disabled magic kwargs for these, and since
no one has complained about it we don't have any incentive to fix it now.
- The inspect reserved control command did not work properly.
- Should now play better with static analyzation tools by explicitly
specifying dynamically created attributes in the celery and
celery.task modules.
- Terminating a task now results in
celery.exceptions.RevokedTaskError instead of a WorkerLostError.
- AsyncResult.revoke now accepts terminate and signal arguments.
- The task-revoked event now includes new fields: terminated,
signum, and expired.

- Now depends on kombu 2.3.1 + billiard 2.7.3.11
- Fixed a bug with the -B option (``cannot pickle thread.lock objects``)
(Issue #894 + Issue #892, + django-celery #154).
- The restart_pool control command now requires the
CELERYD_POOL_RESTARTS setting to be enabled
This change was necessary as the multiprocessing event that the restart
command depends on is responsible for creating many semaphores/file
descriptors, resulting in problems in some environments.
- chain.apply now passes args to the first task (Issue #889).
- Documented previously secret options to the Django-Celery monitor
in the monitoring userguide (Issue #396).
- Old changelog are now organized in separate documents for each series,
history.

- New experimental standalone Celery monitor: Flower

Contributed by Mher Movsisyan.
- Now supports AMQP heartbeats if using the new pyamqp:// transport.
- The py-amqp transport requires the amqp library to be installed:
$ pip install amqp
- Then you need to set the transport URL prefix to pyamqp://.
- The default heartbeat value is 10 seconds, but this can be changed using
the BROKER_HEARTBEAT setting
BROKER_HEARTBEAT = 5.0
- If the broker heartbeat is set to 10 seconds, the heartbeats will be
monitored every 5 seconds (double the hertbeat rate).
See the Kombu 2.3 changelog for more information.
- Now supports RabbitMQ Consumer Cancel Notifications, using the pyamqp://
transport.
This is essential when running RabbitMQ in a cluster.
See the Kombu 2.3 changelog for more information.
- Delivery info is no longer passed directly through.
It was discovered that the SQS transport adds objects that can't
be pickled to the delivery info mapping, so we had to go back
to using the whitelist again.
Fixing this bug also means that the SQS transport is now working again.
- The semaphore was not properly released when a task was revoked (Issue #877).
This could lead to tasks being swallowed and not released until a worker
restart.
Thanks to Hynek Schlawack for debugging the issue.
- Retrying a task now also forwards any linked tasks.
This means that if a task is part of a chain (or linked in some other

- Beat: now works with timezone aware datetime's.
- Task classes inheriting from celery import Task
mistakingly enabled accept_magic_kwargs.
- Fixed bug in inspect scheduled (Issue #829).
- Beat: Now resets the schedule to upgrade to UTC.
- The celery worker command now works with eventlet/gevent.
Previously it would not patch the environment early enough.
- The celery command now supports extension commands
using setuptools entry-points.
Libraries can add additional commands to the celery
command by adding an entry-point like::
setup(
entry_points=[

The command must then support the interface of
celery.bin.base.Command.
