2.4.0
=====
:release-date: 2011-11-04 04:00 P.M GMT
:by: Ask Solem
.. _240-important:
Important Notes
---------------
This release adds `South`_ migrations, which well assist users in automatically
updating their database schemas with each django-celery release.
.. _`South`: http://pypi.python.org/pypi/South/
.. _240-news:
News
----
* Now depends on Celery 2.4.0 or higher.
* South migrations have been added.
Migration 0001 is a snapshot from the previous stable release (2.3.3).
For those who do not use South, no action is required.
South users will want to read the :ref:`240-upgrade-south` section
below.
Contributed by Greg Taylor.
* Test runner now compatible with Django 1.4.
Test runners are now classes instead of functions,
so you have to change the ``TEST_RUNNER`` setting to read::
TEST_RUNNER = "djcelery.contrib.test_runner.CeleryTestSuiteRunner"
Contributed by Jonas Haag.
.. _240-upgrade_south:
Upgrading for south users
-------------------------
For those that are already using django-celery 2.3.x, you'll need to fake the
newly added migration 0001, since your database already has the current
``djcelery_*`` and ``celery_*`` tables::
$ python manage.py migrate djcelery 0001 --fake
If you're upgrading from the 2.2.x series, you'll want to drop/reset your
``celery_*`` and ``djcelery_*`` tables and run the migration::
$ python manage.py migrate djcelery
.. _version-2.3.3:
2.3.3
=====
:release-date: 2011-08-22 12:00 AM BST
* Precedence issue caused database backend tables to not be
created (Issue #62).
.. _version-2.3.2:
2.3.2
=====
:release-date: 2011-08-20 12:00 AM BST
* Fixes circular import of DatabaseBackend.
.. _version-2.3.1:
2.3.1
=====
:release-date: 2011-08-11 12:00 PM BST
* Django database result backend tables were not created.
If you are having troubles because of this, be sure you do a ``syncdb``
after upgrading, that should resolve the issue.
.. _version-2.3.0:
2.3.0
=====
:release-date: 2011-08-05 12:00 PM BST
* Now depends on Celery 2.3.0
Please read the Celery 2.3.0 changelog!
.. _version-2.2.4:
2.2.4
=====
* celerybeat: DatabaseScheduler would not react to changes when using MySQL and
the default transaction isolation level ``REPEATABLE-READ`` (Issue #41).
It is still recommended that you use isolation level ``READ-COMMITTED``
(see the Celery FAQ).
.. _version-2.2.3:
2.2.3
=====
:release-date: 2011-02-12 16:00 PM CET
* celerybeat: DatabaseScheduler did not respect the disabled setting after restart.
* celeryevcam: Expiring objects now works on PostgreSQL.
* Now requires Celery 2.2.3
.. _version-2.2.2:
2.2.2
=====
:release-date: 2011-02-03 16:00 PM CET
* Now requires Celery 2.2.2
* Periodic Task Admin broke if the CELERYBEAT_SCHEDULE setting was not set.
* DatabaseScheduler No longer creates duplicate interval models.
* The djcelery admin templates were not included in the distribution.
.. _version-2.2.1:
2.2.1
=====
:release-date: 2011-02-02 16:00 PM CET
* Should now work with Django versions previous to 1.2.
.. _version-2.2.0:
2.2.0
=====
:release-date: 2011-02-01 10:00 AM CET
* Now depends on Celery v2.2.0
* djceleryadm: Adds task actions Kill and Terminate task
* celerycam: Django's queryset.delete() fetches everything in
memory THEN deletes, so we need to use raw SQL to expire objects.
* djcelerymon: Added Command.stdout + Command.stderr (Issue #23).
* Need to close any open database connection after any embedded
celerybeat process forks.
* Added contrib/requirements/py25.txt
* Demoproject now does ``djcelery.setup_loader`` in settings.py.
.. _version-2.1.1:
2.1.1
=====
:release-date: 2010-10-14 02:00 PM CEST
* Now depends on Celery v2.1.1.
* Snapshots: Fixed bug with losing events.
* Snapshots: Limited the number of worker timestamp updates to once every second.
* Snapshot: Handle transaction manually and commit every 100 task updates.
* snapshots: Can now configure when to expire task events.
New settings:
* ``CELERYCAM_EXPIRE_SUCCESS`` (default 1 day),
* ``CELERYCAM_EXPIRE_ERROR`` (default 3 days), and
* ``CELERYCAM_EXPIRE_PENDING`` (default 5 days).
* Snapshots: ``TaskState.args`` and ``TaskState.kwargs`` are now
represented as ``TextField`` instead of ``CharField``.
If you need to represent arguments larger than 200 chars you have
to migrate the table.
* ``transaction.commit_manually`` doesn't accept arguments on older
Django version.
Should now work with Django versions previous to v1.2.
* The tests doesn't need :mod:`unittest2` anymore if running on Python 2.7.
.. _version-2.1.0:
2.1.0
=====
:release-date: 2010-10-08 12:00 PM CEST
Important Notes
---------------
This release depends on Celery version 2.1.0.
Be sure to read the Celery changelog before you upgrade:
http://ask.github.com/celery/changelog.html#version-2-1-0
News
----
* The periodic task schedule can now be stored in the database and edited via
the Django Admin interface.
To use the new database schedule you need to start ``celerybeat`` with the
following argument::
$ python manage.py celerybeat -S djcelery.schedulers.DatabaseScheduler
Note that you need to add your old periodic tasks to the database manually
(using the Django admin interface for example).
* New Celery monitor for the Django Admin interface.
To start monitoring your workers you have to start your workers
in event mode::
$ python manage.py celeryd -E
(you can do this without restarting the server too::
>>> from celery.task.control import broadcast
>>> broadcast("enable_events")
You need to do a syncdb to create the new tables:
python manage.py syncdb
Then you need to start the snapshot camera::
$ python manage.py celerycam -f 2.0
This will take a snapshot of the events every 2 seconds and store it in
the database.
Fixes
-----
* database backend: Now shows warning if polling results with transaction isolation level
repeatable-read on MySQL.
See http://github.com/ask/django-celery/issues/issue/6
* database backend: get result does no longer store the default result to
database.
See http://github.com/ask/django-celery/issues/issue/6
2.0.2
=====
Important notes
---------------
* Due to some applications loading the Django models lazily, it is recommended
that you add the following lines to your ``settings.py``::
import djcelery
djcelery.setup_loader()
This will ensure the Django celery loader is set even though the
model modules haven't been imported yet.
News
----
* ``djcelery.views.registered_tasks``: Added a view to list currently known
tasks.
2.0.0
=====
:release-date: 2010-07-02 02:30 P.M CEST
