Summary: Potential Bug in
utils/dag_processing/DagFileProcessorManager.max_runs_reached()
Key: AIRFLOW-3183
URL: https://issues.apache.org/jira/browse/AIRFLOW-3183
Project: Apache Airflow
Issue Type: Bug
Reporter: Xiaodong DENG
Assignee: Xiaodong DENG
In
[https://github.com/apache/incubator-airflow/blob/df7c16a3ce01625277dd2e5c4ce4ed096dcfbb40/airflow/utils/dag_processing.py#L581,]
the condition is to ensure the function will return False if any file's
run_count is smaller than max_run.
But the operator used here is "!=". Instead, it should be "<".
This is because in *DagFileProcessorManager*, there is no statement helping
limit the upper limit of run_count. It's possible that files' run_count will be
bigger than max_run. In such case, max_runs_reached() method may fail its
purpose.
