## Why
Tasks that fail with non zero exit codes (like exit code 1) were not
retrying even when retries were configured. This occurred when processes exited
abnormally in a task, such as:
- External command failures (e.g., `git fetch` failing with exit code 1)
- Network timeouts in subprocess operations
- Any process that exits with a positive exit code before Python exception
handling
Previously, only tasks terminated by signals (negative exit codes) would be
retried. Normal failures with positive exit codes would immediately fail
without checking if retries were available.
## Testing
DAG used:
```python
from airflow.sdk import DAG
from datetime import datetime
from airflow.providers.standard.operators.bash import BashOperator
dag = DAG(
"test_retry_exit_code",
start_date=datetime(2024, 1, 1),
schedule=None,
catchup=False,
)
task = BashOperator(
task_id="git_fetch_fail",
bash_command="git fetch invalid-remote || exit 1",
retries=3,
dag=dag,
)
```
Works as expected
