michaltarana opened a new issue, #57197:
URL: https://github.com/apache/airflow/issues/57197
### Apache Airflow version
Other Airflow 2/3 version (please specify below)
### If "Other Airflow 2/3 version" selected, which one?
3.0.3
### What happened?
$AIRFLOW_HOME/dags subdirectory appears in sys.path when the DAG is
triggered from the UI. It is not in sys.path when the DAG is triggered using
the cli.
### What you think should happen instead?
According to the documentation (HowTo Guides - Setting Configuration
Options):
> Starting from Airflow 2.10.1, the $AIRFLOW_HOME/dags folder is no longer
included in sys.path at initialization, so any local settings in that folder
will not be imported.
I believe that this should be consistent, regardless of the way the DAG is
triggered (UI or cli). Therefore, the subdirectory $AIRFLOW_HOME/dags should
*not* appear in sys.path when the DAG is triggered from the UI.
### How to reproduce
1. Create a simple DAG:
```
from airflow.sdk import DAG, task
import sys
from pprint import pprint
pprint(sys.path)
@task(executor="LocalExecutor")
def report_local():
print(f"Airflow with executor 'LocalExecutor' is running")
with DAG(
dag_id="simple_dag"
) as dag:
report_local()
```
2. Execute ```airflow dags test simple_dag```
3. Check whether the output looks like this:
```
['/home/airflow/.local/bin',
'/usr/local/lib/python312.zip',
'/usr/local/lib/python3.12',
'/usr/local/lib/python3.12/lib-dynload',
'/home/airflow/.local/lib/python3.12/site-packages',
'/opt/airflow/config',
'/opt/airflow/plugins']
```
(no /opt/airflow/dags).
4. Trigger the same DAG from the web UI.
5. Check whether the result looks like this:
```
['/home/airflow/.local/bin',
'/usr/local/lib/python312.zip',
'/usr/local/lib/python3.12',
'/usr/local/lib/python3.12/lib-dynload',
'/home/airflow/.local/lib/python3.12/site-packages',
'/opt/airflow/config',
'/opt/airflow/plugins',
'/opt/airflow/dags']
```
