----------------------------------
Summary: DAG context manager fails to exit properly in certain
circumstances
Key: AIRFLOW-3060
URL: https://issues.apache.org/jira/browse/AIRFLOW-3060
Project: Apache Airflow
Issue Type: Bug
Components: DAG
Reporter: Newton Le
Assignee: Newton Le
In certain circumstances, such as in more complex DAGs where users utilize
helper functions to add tasks, it may be possible to get into a condition where
effectively there is a nested DAG context using the same DAG. When this
happens, exiting both contexts does not reset `_CONTEXT_MANAGER_DAG`.
This is especially problematic because the problem is seen in a later DAG, and
the source of the error is not apparent.
