"""
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 does not dispatch the task directly, but instead promises to dispatch it later by
encapsulating the desired task through a call to a :func:`_queue_reserved_task` task. See
the docblock on :func:`_queue_reserved_task` for more information on this.
This method creates a :class:`pulpcore.app.models.Task` object. Pulp expects to poll on a
task just after calling this method, so a Task entry needs to exist for it
before it returns.
Args:
func (callable): The function to be run by RQ when the necessary locks are acquired.
resources (list): A list of resources to reserve guaranteeing that only one task reserves
these resources. Each resource can be either a (str) resource URL or a
(django.models.Model) resource instance.
args (tuple): The positional arguments to pass on to the task.
kwargs (dict): The keyword arguments to pass on to the task.
options (dict): The options to be passed on to the task.
task_group (pulpcore.app.models.TaskGroup): A TaskGroup to add the created Task to.
Returns (rq.job.job): An RQ Job instance as returned by RQ's enqueue function
Raises:
ValueError: When `resources` is an unsupported type.
