> Project: Apache Airflow
> Issue Type: Bug
> Components: DAG
> Affects Versions: 1.10.3, 1.10.4, 1.10.5
> Reporter: Daniel Imberman
> Assignee: Daniel Imberman
> Priority: Critical
> Fix For: 2.0.0

> DAG Parsing is currently breaking for long DAGs because test_cycle uses
> recursive DFS
> Example breaking DAG
>
> {code:java}
> dag = DAG( 'dag', start_date=DEFAULT_DATE, default_args={'owner': 'owner1'})
> with dag:
> last = dag
> for i in range(1,10000):
> op = DummyOperator(task_id='{}'.format(i))
> last >> op
> last = op
> {code}
