Tue Feb 12 21:42:37 UTC 2013 - alexandre@exatati.com.br

- Update to 3.0.15:
  - Now depends on billiard 2.7.3.21 which fixed a syntax error crash.
  - Fixed bug with CELERY_SEND_TASK_SENT_EVENT.

-------------------------------------------------------------------
Fri Feb  8 20:10:26 UTC 2013 - alexandre@exatati.com.br

- Update to 3.0.14:
  - Now depends on Kombu 2.5.6
  - Now depends on billiard 2.7.3.20
  - execv is now disabled by default.
    It was causing too many problems for users, you can still enable
    it using the CELERYD_FORCE_EXECV setting.
    execv was only enabled when transports other than amqp/redis was used,
    and it's there to prevent deadlocks caused by mutexes not being released
    before the process forks.  Sadly it also changes the environment
    introducing many corner case bugs that is hard to fix without adding
    horrible hacks.  Deadlock issues are reported far less often than the
    bugs that execv are causing, so we now disable it by default.
    Work is in motion to create non-blocking versions of these transports
    so that execv is not necessary (which is the situation with the amqp
    and redis broker transports)
  - Chord exception behavior defined (Issue #1172).
    From Celery 3.1 the chord callback will change state to FAILURE
    when a task part of a chord raises an exception.
    It was never documented what happens in this case,
    and the actual behavior was very unsatisfactory, indeed
    it will just forward the exception value to the chord callback.
    For backward compatibility reasons we do not change to the new
    behavior in a bugfix release, even if the current behavior was
    never documented.  Instead you can enable the
    CELERY_CHORD_PROPAGATES setting to get the new behavior
    that will be default from Celery 3.1.
    See more at chord-errors.
  - worker: Fixes bug with ignored and retried tasks.
    The on_chord_part_return and Task.after_return callbacks,
    nor the task_postrun signal should be called when the task was
    retried/ignored.
    Fix contributed by Vlad.
  - GroupResult.join_native now respects the propagate argument.
  - subtask.id added as an alias to subtask['options'].id
        >>> s = add.s(2, 2)
        >>> s.id = 'my-id'
        >>> s['options']
        {'task_id': 'my-id'}

        >>> s.id
        'my-id'
  - worker: Fixed error `Could not start worker processes` occurring
    when restarting after connection failure (Issue #1118).
  - Adds new signal task-retried (Issue #1169).
  - `celery events --dumper` now handles connection loss.
  - Will now retry sending the task-sent event in case of connection failure.
  - amqp backend:  Now uses Message.requeue instead of republishing
    the message after poll.
  - New BROKER_HEARTBEAT_CHECKRATE setting introduced to modify the
    rate at which broker connection heartbeats are monitored.
    The default value was also changed from 3.0 to 2.0.
  - celery.events.state.State is now pickleable.
    Fix contributed by Mher Movsisyan.
  - celery.datastructures.LRUCache is now pickleable.
    Fix contributed by Mher Movsisyan.
  - The stats broadcast command now includes the workers pid.
    Contributed by Mher Movsisyan.
  - New conf remote control command to get a workers current configuration.
    Contributed by Mher Movsisyan.
  - Adds the ability to modify the chord unlock task's countdown
    argument (Issue #1146).
    Contributed by Jun Sakai
  - beat: The scheduler now uses the now() method of the schedule,
    so that schedules can provide a custom way to get the current date and time.
    Contributed by Raphaël Slinckx
  - Fixed pickling of configuration modules on Windows or when execv is used
    (Issue #1126).
  - Multiprocessing logger is now configured with loglevel ERROR
    by default.
    Since 3.0 the multiprocessing loggers were disabled by default
    (only configured when the MP_LOG environment variable was set).

-------------------------------------------------------------------
Mon Jan  7 16:34:24 UTC 2013 - alexandre@exatati.com.br

- Update to 3.0.13:
  - Now depends on Kombu 2.5
    - py-amqp has replaced amqplib as the default transport,
      gaining support for AMQP 0.9, and the RabbitMQ extensions
      including Consumer Cancel Notifications and heartbeats.
    - support for multiple connection URLs for failover.
    - Read more in the Kombu 2.5 changelog.
  - Now depends on billiard 2.7.3.19
  - Fixed a deadlock issue that could occur when the producer pool
    inherited the connection pool instance of the parent process.
  - The --loader option now works again (Issue #1066).
  - celery umbrella command: All subcommands now supports
    the --workdir option (Issue #1063).
  - Groups included in chains now give GroupResults (Issue #1057)
    Previously it would incorrectly add a regular result instead of a group
    result, but now this works:

        # [4 + 4, 4 + 8, 16 + 8]
        >>> res = (add.s(2, 2) | group(add.s(4), add.s(8), add.s(16)))()
        >>> res
        <GroupResult: a0acf905-c704-499e-b03a-8d445e6398f7 [
            4346501c-cb99-4ad8-8577-12256c7a22b1,
            b12ead10-a622-4d44-86e9-3193a778f345,
            26c7a420-11f3-4b33-8fac-66cd3b62abfd]>

  - Chains can now chain other chains and use partial arguments (Issue #1057).
    Example:
        >>> c1 = (add.s(2) | add.s(4))
        >>> c2 = (add.s(8) | add.s(16))

        >>> c3 = (c1 | c2)

        # 8 + 2 + 4 + 8 + 16
        >>> assert c3(8).get() == 38

  - Subtasks can now be used with unregistered tasks.
    You can specify subtasks even if you just have the name:

        >>> s = subtask(task_name, args=(), kwargs=())
        >>> s.delay()

  - The celery shell command now always adds the current
    directory to the module path.
  - The worker will now properly handle the pytz.AmbiguousTimeError
    exception raised when an ETA/countdown is prepared while being in DST
    transition (Issue #1061).
  - force_execv: Now makes sure that task symbols in the original
    task modules will always use the correct app instance (Issue #1072).
  - AMQP Backend: Now republishes result messages that have been polled
    (using result.ready() and friends, result.get() will not do this
    in this version).
  - Crontab schedule values can now "wrap around"
    This means that values like ``11-1`` translates to ``[11, 12, 1]``.
    Contributed by Loren Abrams.
  - multi stopwait command now shows the pid of processes.
    Contributed by Loren Abrams.
  - Handling of ETA/countdown fixed when the CELERY_ENABLE_UTC
    setting is disabled (Issue #1065).
  - A number of uneeded properties were included in messages,
    caused by accidentally passing Queue.as_dict as message properties.
  - Rate limit values can now be float
    This also extends the string format so that values like "0.5/s" works.
    Contributed by Christoph Krybus
  - Fixed a typo in the broadcast routing documentation (Issue #1026).
  - Rewrote confusing section about idempotence in the task user guide.
  - Fixed typo in the daemonization tutorial (Issue #1055).
  - Fixed several typos in the documentation.
    Contributed by Marius Gedminas.
  - Batches: Now works when using the eventlet pool.
    Fix contributed by Thomas Grainger.
  - Batches: Added example sending results to celery.contrib.batches.
    Contributed by Thomas Grainger.
  - Mongodb backend: Connection max_pool_size can now be set in
    CELERY_MONGODB_BACKEND_SETTINGS.
    Contributed by Craig Younkins.
  - Fixed problem when using earlier versions of pytz.
    Fix contributed by Vlad.
  - Docs updated to include the default value for the
    CELERY_TASK_RESULT_EXPIRES setting.
  - Improvements to the django-celery tutorial.
    Contributed by Locker537.
  - The add_consumer control command did not properly persist
    the addition of new queues so that they survived connection failure
    (Issue #1079).

-------------------------------------------------------------------
Tue Nov  6 18:00:40 UTC 2012 - alexandre@exatati.com.br

- Update to 3.0.12:
  - Now depends on kombu 2.4.8
    - [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.
  - Development documentation has moved to Read The Docs.
    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.
    Fix contributed by Remigiusz Modrzejewski
  - 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.
  - Fixed strange kombu import problem on Python 3.2 (Issue #1034).
  - Worker: ETA scheduler now uses millisecond precision (Issue #1040).
  - The --config argument to programs is now supported by all loaders.
  - The CASSANDRA_OPTIONS setting has now been documented.
    Contributed by Jared Biel.
  - Task methods celery.contrib.methods cannot be used with the old
    task base class, the task decorator in that module now inherits from the new.
  - An optimization was too eager and caused some logging messages to never emit.
  - celery.contrib.batches now works again.
  - Fixed missing whitespace in bdist_rpm requirements (Issue #1046).
  - Event state's tasks_by_name applied limit before filtering by name.
    Fix contributed by Alexander A. Sosnovskiy.

-------------------------------------------------------------------
Wed Sep 26 17:42:49 UTC 2012 - alexandre@exatati.com.br

- Update to 3.0.11:
  - 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:

            http://github.com/celery/celery/tree/3.0/extra/generic-init.d

  - 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).

    Fix contributed by Alexey Zatelepin
  - Terminating a task now properly updates the state of the task to revoked,
    and sends a ``task-revoked`` event.
  - Multi: No longer parses --app option (Issue #1008).
  - Generic worker init script now waits for workers to shutdown by default.
  - Multi: stop_verify command renamed to stopwait.
  - Daemonization: Now delays trying to create pidfile/logfile until after
    the working directory has been changed into.
  - celery worker and celery beat commands now respects
    the --no-color option (Issue #999).
  - Fixed typos in eventlet examples (Issue #1000)

    Fix contributed by Bryan Bishop.
    Congratulations on opening bug #1000!
  - Tasks that raise celery.exceptions.Ignore are now acknowledged.
  - Beat: Now shows the name of the entry in sending due task logs.


-------------------------------------------------------------------
Thu Sep 20 22:24:32 UTC 2012 - alexandre@exatati.com.br

- Update to 3.0.10:
  - 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.

    Example:

        from celery.exceptions import Ignore

        @task
        def custom_revokes():
            if redis.sismember('tasks.revoked', custom_revokes.request.id):
                raise Ignore()

  - The worker now makes sure the request/task stacks are not modified
    by the initial Task.__call__.

    This would previously be a problem if a custom task class defined
    __call__ and also called super().
  - Because of problems the fast local optimization has been disabled,
    and can only be enabled by setting the USE_FAST_LOCALS attribute.
  - Worker: Now sets a default socket timeout of 5 seconds at shutdown
    so that broken socket reads do not hinder proper shutdown (Issue #975).
  - More fixes related to late eventlet/gevent patching.
  - Documentation for settings out of sync with reality:

    - CELERY_TASK_PUBLISH_RETRY

        Documented as disabled by default, but it was enabled by default
        since 2.5 as stated by the 2.5 changelog.

    - CELERY_TASK_PUBLISH_RETRY_POLICY

        The default max_retries had been set to 100, but documented as being
        3, and the interval_max was set to 1 but documented as 0.2.
        The default setting are now set to 3 and 0.2 as it was originally
        documented.

    Fix contributed by Matt Long.
  - Worker: Log messages when connection established and lost have been improved.
  - The repr of a crontab schedule value of '0' should be '*'  (Issue #972).
  - Revoked tasks are now removed from reserved/active state in the worker
    (Issue #969)

    Fix contributed by Alexey Zatelepin.
  - gevent: Now supports hard time limits using gevent.Timeout.
  - Documentation: Links to init scripts now point to the 3.0 branch instead
    of the development branch (master).
  - Documentation: Fixed typo in signals user guide (Issue #986).

    instance.app.queues -> instance.app.amqp.queues.
  - Eventlet/gevent: The worker did not properly set the custom app
    for new greenlets.
  - Eventlet/gevent: Fixed a bug where the worker could not recover
    from connection loss (Issue #959).

    Also, because of a suspected bug in gevent the
    BROKER_CONNECTION_TIMEOUT setting has been disabled
    when using gevent


-------------------------------------------------------------------
Fri Aug 31 23:44:00 UTC 2012 - alexandre@exatati.com.br

- Update to 3.0.9:
  - 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:

        pipe = sometask.s() | othertask.s()
        new_pipe = mytask.s() | pipe

    Contributed by Steve Morin.
  - Fixed problem with group results on non-pickle serializers.
    Fix contributed by Steeve Morin.

-------------------------------------------------------------------
Wed Aug 29 18:02:17 UTC 2012 - alexandre@exatati.com.br

- Update to 3.0.8:
  - Now depends on Kombu 2.4.4
  - 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.
    Contributed by Mher Movsisyan.
  - 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).
    Fix contributed by Thomas Meson.

-------------------------------------------------------------------
Fri Aug 24 22:30:22 UTC 2012 - alexandre@exatati.com.br

- Update to 3.0.7:
  - Fixes several problems with periodic tasks and timezones (Issue #937).
  - 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.
    Fix contributed by Steeve Morin.
  - Cassandra backend now works if result expiry is disabled.
    Fix contributed by Steeve Morin.
  - The traceback object is now passed to signal handlers instead
    of the string representation.
    Fix contributed by Adam DePue.
  - 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.

-------------------------------------------------------------------
Fri Aug 17 22:34:07 UTC 2012 - alexandre@exatati.com.br

- Update to 3.0.6:
  - 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.
  - The argument to celery.exceptions.TaskRevokedError is now one
    of the reasons revoked, expired or terminated.
  - Old Task class does no longer use classmethods for push_request and
    pop_request  (Issue #912).
  - GroupResult now supports the children attribute (Issue #916).
  - AsyncResult.collect now respects the intermediate argument
    (Issue #917).
  - Fixes example task in documentation (Issue #902).
  - Eventlet fixed so that the environment is patched as soon as possible.
  - eventlet: Now warns if celery related modules that depends on threads
    are imported before eventlet is patched.
  - Improved event and camera examples in the monitoring guide.
  - Disables celery command setuptools entrypoints if the command can't be
    loaded.
  - Fixed broken dump_request example in the tasks guide.

-------------------------------------------------------------------
Wed Aug  1 18:58:47 UTC 2012 - alexandre@exatati.com.br

- Update to 3.0.5:
  - 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.

-------------------------------------------------------------------
Thu Jul 26 22:18:34 UTC 2012 - alexandre@exatati.com.br

- Update to 3.0.4:
  - Now depends on Kombu 2.3
  - New experimental standalone Celery monitor: Flower
    See monitoring-flower to read more about it!

    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
    way) and that even if the task is retried, then the next task in the chain
    will be executed when the retry succeeds.

  - Chords: Now supports setting the interval and other keyword arguments
    to the chord unlock task.
    - The interval can now be set as part of the chord subtasks kwargs::

        chord(header)(body, interval=10.0)

    - In addition the chord unlock task now honors the Task.default_retry_delay
      option, used when none is specified, which also means that the default
      interval can also be changed using annotations:

            CELERY_ANNOTATIONS = {
                'celery.chord_unlock': {
                    'default_retry_delay': 10.0,
                }
            }

  - New @Celery.add_defaults method can add new default configuration
    dicts to the applications configuration.

    For example:

        config = {'FOO': 10}

        celery.add_defaults(config)

    is the same as celery.conf.update(config) except that data will not be
    copied, and that it will not be pickled when the worker spawns child
    processes.

    In addition the method accepts a callable:

        def initialize_config():
            # insert heavy stuff that can't be done at import time here.

        celery.add_defaults(initialize_config)

    which means the same as the above except that it will not happen
    until the celery configuration is actually used.

    As an example, Celery can lazily use the configuration of a Flask app::

        flask_app = Flask()
        celery = Celery()
        celery.add_defaults(lambda: flask_app.config)

  - Revoked tasks were not marked as revoked in the result backend (Issue #871).

    Fix contributed by Hynek Schlawack.

  - Eventloop now properly handles the case when the epoll poller object
    has been closed (Issue #882).

  - Fixed syntax error in funtests/test_leak.py

    Fix contributed by Catalin Iacob.

  - group/chunks: Now accepts empty task list (Issue #873).
  - New method names:

    - Celery.default_connection() ➠  @Celery.connection_or_acquire.
    - Celery.default_producer()   ➠  @Celery.producer_or_acquire.

    The old names still work for backward compatibility.

Fri Jul 20 21:12:59 UTC 2012 - alexandre@exatati.com.br

- Update to 3.0.3:
  - amqplib passes the channel object as part of the delivery_info
    and it's not pickleable, so we now remove it.

-------------------------------------------------------------------
Tue Jul 10 22:43:17 UTC 2012 - alexandre@exatati.com.br

- Update to 3.0.1:
  - Now depends on kombu 2.2.5
  - inspect now supports limit argument::
    myapp.control.inspect(limit=1).ping()
  - 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=[
                'celery.commands': [
                    'foo = my.module:Command',
            ],
        ],
        ...)

    The command must then support the interface of
    celery.bin.base.Command.
  - contrib.migrate: New utilities to move tasks from one queue to another.
    - celery.contrib.migrate.move_tasks
    - celery.contrib.migrate.move_task_by_id

-------------------------------------------------------------------
Thu Mar  1 17:47:07 UTC 2012 - alexandre@exatati.com.br

- Update to 2.5.1:
  * Eventlet/Gevent: A small typo caused celeryd to hang when eventlet/gevent
    was used, this was because the environment was not monkey patched
    early enough.
  * Eventlet/Gevent: Another small typo caused the mediator to be started
    with eventlet/gevent, which would make celeryd sometimes hang at shutdown.
  * Mulitprocessing: Fixed an error occurring if the pool was stopped
    before it was properly started.
  * Proxy objects now redirects __doc__ and __name__ so help(obj)
    works.
  * Internal timer (timer2) now logs exceptions instead of swallowing them
  * celeryctl shell: can now be started with --eventlet or
    --gevent options to apply their monkey patches.

Sun Feb 20 18:43:50 UTC 2011 - alexandre@exatati.com.br

- Update to 2.2.4:
  * celeryd: 2.2.3 broke error logging, resulting in tracebacks not being logged.
  * AMQP result backend: Polling task states did not work properly if there were
    more than one result message in the queue.
  * TaskSet.apply_async() and TaskSet.apply() now supports an optional
    taskset_id keyword argument (Issue #331).
  * The current taskset id (if any) is now available in the task context as
    request.context (Issue #329).
  * SQLAlchemy result backend: date_done was no longer part of the results as it had
    been accidentally removed.  It is now available again (Issue #325).
  * SQLAlchemy result backend: Added unique constraint on Task.task_id and
    TaskSet.taskset_id.  Tables needs to be recreated for this to take effect.

-------------------------------------------------------------------
Sat Feb 12 17:06:00 UTC 2011 - alexandre@exatati.com.br

- Update to 2.2.3:
  - Now depends on Kombu 1.0.3
  - Task.retry now supports a max_retries argument, used to change
    the default value.
  - multiprocessing.cpu_count may raise NotImplementedError on
    platforms where this is not supported (Issue #320).
  - Coloring of log messages broke if the logged object was not a
    string.
  - Fixed several typos in the init script documentation.
  - A regression caused Task.exchange and Task.routing_key to no
    longer have any effect. This is now fixed.
  - Routing Userguide: Fixes typo, routers in CELERY_ROUTES must be
    instances, not classes.
  - celeryev did not create pidfile even though the --pidfile
    argument was set.
  - Task logger format was no longer used. (Issue #317).
      The id and name of the task is now part of the log message
      again.
  - A safe version of repr() is now used in strategic places to
    ensure objects with a broken __repr__ does not crash the
    worker, or otherwise make errors hard to understand (Issue #298).
  - Remote control command active_queues: did not account for
    queues added at runtime.
      In addition the dictionary replied by this command now has a
      different structure: the exchange key is now a dictionary
      containing the exchange declaration in full.
  - The -Q option to celeryd removed unused queue declarations, so
    routing of tasks could fail.
      Queues are no longer removed, but rather
      app.amqp.queues.consume_from() is used as the list of queues
      to consume from.
      This ensures all queues are available for routing purposes.
  - celeryctl: Now supports the inspect active_queues command.

-------------------------------------------------------------------
Thu Feb  3 22:37:08 UTC 2011 - alexandre@exatati.com.br

  * The eta argument can now be used with task.retry.
    Previously it was overwritten by the countdown argument.
  * celeryd-multi/celeryd_detach: Now logs errors occuring when
    executing the celeryd command.
  * daemonizing cookbook: Fixed typo --time-limit 300 ->
    --time-limit=300
  * Colors in logging broke non-string objects in log messages.
  * setup_task_logger no longer makes assumptions about
    magic task kwargs.

-------------------------------------------------------------------
Wed Feb  2 17:33:41 UTC 2011 - alexandre@exatati.com.br

-------------------------------------------------------------------
Sat Dec  4 09:22:02 UTC 2010 - alexandre@exatati.com.br

- Update to 2.1.4:
  * Celery programs now hijacks the root logger by default (Issue #250).
  * Execution options to apply_async now takes precedence over options
    returned by active routers.  This was a regression introduced recently
    (Issue #244).
  * celeryev curses monitor: Long arguments are now truncated so curses
    doesn't crash with out of bounds errors.  (Issue #235).
  * celeryd: Channel errors occurring while handling control commands no
    longer crash the worker but are instead logged with severity error.
  * SQLAlchemy database backend: Fixed a race condition occurring when
    the client wrote the pending state.  Just like the Django database backend,
    it does no longer save the pending state (Issue #261 + Issue #262).
  * task.apply: propagate=True now raises exceptions from the original
    frame, keeping the same stacktrace (Issue #256).
  * Error email body now uses repr(exception) instead of str(exception),
    as the latter could result in Unicode decode errors (Issue #245).
  * Error e-mail timeout value is now configurable by using the
    :setting:EMAIL_TIMEOUT setting.
  * celeryev: Now works on Windows (but the curses monitor won't work without
    having curses).
  * Unit test output no longer emits non-standard characters.
  * celeryd: The broadcast consumer is now closed if the connection is reset.
  * celeryd: Now properly handles errors occurring while trying to acknowledge
    the message.
