Arguments: main (str): Name of the main module if running as `__main__`. This is used as the prefix for auto-generated task names.

If you're depending on binding to be deferred, then you must not access any attributes on the returned object until the application is fully set up (finalized). �lazyTr1 )� shared_taskFNc s |� � ����fdd�}|S )Nc sr �r"� �fdd�}� j |_ t|� �r,�jr@�j� fi ���}n"t�j� f�� jd�}�j�|� �rn�|�S |S )Nc s | j � fi ���S r] )�_task_from_fun�rG )�fun�optsrI rJ �cons� s zRCelery.task.<locals>.inner_create_task_cls.<locals>._create_task_cls.<locals>.cons)�__doc__)rF r r� r� r! r� r� �append)r� r� �ret)�_filtr� r� rZ �shared)r� rJ �_create_task_cls� s � zDCelery.task.<locals>.inner_create_task_cls.<locals>._create_task_clsrI )r� �filterr� r� r� rd )r� r� r� r� rJ �inner_create_task_cls� s z*Celery.task.<locals>.inner_create_task_clsr z(argument 1 to @task() must be a callablez+@task() takes exactly 1 argument ({} given))TNT) � USING_EXECVr� � r� rj �callable� TypeError�format�sum)rZ rM r� r� r� rI rd rJ �task� s ��z Celery.taskc C s t t||d��S )N��bound)� staticmethodr' )rZ r� r� rI rI rJ � type_checker� s zCelery.type_checkerc K s� | j s| jstd��|p&| �|j|j�}|p0| j}|| jvr�|rD|nt|�}t |j|ft | ||d|j |j|j | j ||d�|d� fi |���� }z |j|_W n ty� Y n0 || j|j< |�| � t|fi |�� n | j| }|S )N�"Contract breach: app not finalizedTr� ) rG r{ �runZ _decoratedr� ro �__annotations__Z __header__� __wrapped__)r� r� � RuntimeErrorr) rF ro �Taskr� r� �type�dictr� r� r� rp �AttributeErrorr{ �bindr5 )rZ r� r{ �baser� �optionsr� r� rI rI rJ r� � s8 � � zCelery._task_from_func K sd t �|�r|� p|}|js4t|�}| �|j|j�|_t|fi |�� || j|j< | |_ |� | � |S )z�Utility for registering a task-based class.

If the argument is a callable function then it will be regarded as a promise, and it won't be loaded until the configuration is actually needed. This method can be compared to: .. code-block:: pycon >>> celery.conf.update(d) with a difference that 1) no copy will be made and 2) the dict will not be transferred when the worker spawns child processes, so it's important that the same configuration happens at import time when pickle restores the object on the other side. c s � S r] rI rI ��drI rJ �<lambda>1 ry z%Celery.add_defaults.<locals>.<lambda>N)r� r� r� � add_defaultsr� r� )rZ r� rI r� rJ r� s zCelery.add_defaultsc C s< || _ |p| j| _|s | jr8d| _| jj||d�r8| jS dS )a Read configuration from object. Object is either an actual object or the name of a module to import. Example: >>> celery.config_from_object('myapp.celeryconfig') >>> from myapp import celeryconfig >>> celery.config_from_object(celeryconfig) Arguments: silent (bool): If true then import errors will be ignored. force (bool): Force reading configuration immediately.

This will affect all application instances (a global operation). Disables untrusted serializers and if configured to use the ``auth`` serializer will register the ``auth`` serializer with the provided settings into the Kombu serializer registry. Arguments: allowed_serializers (Set[str]): List of serializer names, or content_types that should be exempt from being disabled. key (str): Name of private key file to use. Defaults to the :setting:`security_key` setting. key_password (bytes): Password to decrypt the private key. Defaults to the :setting:`security_key_password` setting. cert (str): Name of certificate file to use. Defaults to the :setting:`security_certificate` setting. store (str): Directory containing certificates. Defaults to the :setting:`security_cert_store` setting. digest (str): Digest algorithm used when signing messages. Default is ``sha256``. serializer (str): Serializer used to encode messages after they've been signed. See :setting:`task_serializer` for the serializers supported. Default is ``json``. r )�setup_securityr� )Zcelery.securityr ) rZ Zallowed_serializersr` � key_password�cert�store�digest� serializerr rI rI rJ r e s �zCelery.setup_securityr� c C s0 |r| � ||�S tjjt| j ||�d| d� dS )a� Auto-discover task modules. Searches a list of packages for a "tasks.py" module (or use related_name argument). If the name is empty, this will be delegated to fix-ups (e.g., Django). For example if you have a directory layout like this: .. code-block:: text foo/__init__.py tasks.py models.py bar/__init__.py tasks.py models.py baz/__init__.py models.py Then calling ``app.autodiscover_tasks(['foo', 'bar', 'baz'])`` will result in the modules ``foo.tasks`` and ``bar.tasks`` being imported. Arguments: packages (List[str]): List of packages to search. This argument may also be a callable, in which case the value returned is used (for lazy evaluation). related_name (Optional[str]): The name of the module to find. Defaults to "tasks": meaning "look for 'module.tasks' for every module in ``packages``.". If ``None`` will only try to import the package, i.e. "look for 'module'". force (bool): By default this call is lazy so that the actual auto-discovery won't happen until an application imports the default modules. Forcing will cause the auto-discovery to happen immediately.
