Maik Wild updated AIRFLOW-6237:
-------------------------------
Description:
[inspect.getfullargspec|https://docs.python.org/3/library/inspect.html#inspect.getfullargspec]
will not return any arguments when using the decorator
[apply_defaults|https://github.com/apache/airflow/blob/master/airflow/utils/decorators.py#L31].
When I remove the decorator getfullargspec works as expected.
{code:python}
>>> import inspect
>>> from airflow.operators.dagrun_operator import TriggerDagRunOperator
>>> inspect.getfullargspec(TriggerDagRunOperator)
FullArgSpec(args=[], varargs='args', varkw='kwargs', defaults=None,
kwonlyargs=[], kwonlydefaults=None, annotations={})
>>> inspect.signature(TriggerDagRunOperator)
<Signature (trigger_dag_id, python_callable=None, execution_date=None, *args,
**kwargs)>
{code}
When i remove the decorator from TriggerDagRunOperator.\_\_init\_\_:
{code:python}
>>> import inspect
>>> from airflow.operators.dagrun_operator import TriggerDagRunOperator
>>> inspect.getfullargspec(TriggerDagRunOperator)
FullArgSpec(args=['self', 'trigger_dag_id', 'python_callable',
'execution_date'], varargs='args', varkw='kwargs', defaults=(None, None),
kwonlyargs=[], kwonlydefaults=None, annotations={})
>>> inspect.signature(TriggerDagRunOperator)
<Signature (trigger_dag_id, python_callable=None, execution_date=None, *args,
**kwargs)>
{code}
