pulpcore.plugin.tasking.dispatch(func, resources, args=None, kwargs=None, task_group=None)

Enqueue a message to Pulp workers with a reservation.

This method provides normal enqueue functionality, while also requesting necessary locks for serialized urls. No two tasks that claim the same resource can execute concurrently. It accepts resources which it transforms into a list of urls (one for each resource).

This method creates a pulpcore.app.models.Task object and returns it.

The values in args and kwargs must be JSON serializable, but may contain instances of uuid.UUID.

Parameters

  • func (callable) – The function to be run by RQ when the necessary locks are acquired.

  • resources (list) – A list of resources to this task needs exclusive access to while running. Each resource can be either a str or a django.models.Model instance.

  • args (tuple) – The positional arguments to pass on to the task.

  • kwargs (dict) – The keyword arguments to pass on to the task.

  • task_group (pulpcore.app.models.TaskGroup) – A TaskGroup to add the created Task to.

Returns (pulpcore.app.models.Task): The Pulp Task that was created.

Raises

ValueError – When resources is an unsupported type.
