celery.worker.components

Default worker bootsteps.

class celery.worker.components.Timer(parent, \*kwargs*)[源代码]

This step initializes the internal timer used by the worker.

• create(w)[源代码]

• name = u’celery.worker.components.Timer’

• on_timer_error(exc)[源代码]

• on_timer_tick(delay)[源代码]

• requires = ()

class celery.worker.components.Hub(w, \*kwargs*)[源代码]

• create(w)[源代码]

• include_if(w)[源代码]

• name = u’celery.worker.components.Hub’

• requires = (step:celery.worker.components.Timer{()},)

• start(w)[源代码]

• stop(w)[源代码]

• terminate(w)[源代码]

class celery.worker.components.Queues(parent, \*kwargs*)[源代码]

This bootstep initializes the internal queues used by the worker.

• create(w)[源代码]

• label = ‘Queues (intra)’

• name = u’celery.worker.components.Queues’

• requires = (step:celery.worker.components.Hub{(step:celery.worker.components.Timer{()},)},)

class celery.worker.components.Pool(w, autoscale=None, autoreload=None, no_execv=False, optimization=None, \*kwargs*)[源代码]

Bootstep managing the worker pool.

Describes how to initialize the worker pool, and starts and stops the pool during worker startup/shutdown.

Adds attributes:

• autoscale
• pool
• max_concurrency
• min_concurrency

• close(w)[源代码]

• create(w, semaphore=None, max_restarts=None)[源代码]

• info(w)[源代码]

• name = u’celery.worker.components.Pool’

• register_with_event_loop(w, hub)[源代码]

• requires = (step:celery.worker.components.Queues{(step:celery.worker.components.Hub{(step:celery.worker.components.Timer{()},)},)},)

• terminate(w)[源代码]

class celery.worker.components.Beat(w, beat=False, \*kwargs*)[源代码]

Step used to embed a beat process.

This will only be enabled if the beat argument is set.

• conditional = True

• create(w)[源代码]

• label = ‘Beat’

• name = u’celery.worker.components.Beat’

• requires = ()

class celery.worker.components.StateDB(w, \*kwargs*)[源代码]

This bootstep sets up the workers state db if enabled.

• create(w)[源代码]

• name = u’celery.worker.components.StateDB’

• requires = ()

class celery.worker.components.Consumer(parent, \*kwargs*)[源代码]

• create(w)[源代码]

• last = True

• name = u’celery.worker.components.Consumer’

• requires = ()
