Dev-iL opened a new pull request, #63787:
URL: https://github.com/apache/airflow/pull/63787
## Summary
- Defer `from airflow.configuration import conf, ensure_secrets_loaded` from
module-level to inside `get_connection_from_secrets()`, breaking a circular
import cycle where `airflow.models.Connection` → `airflow.configuration` →
secrets backend init → `airflow.models.Connection`.
## Details
`connection.py` imports `airflow.configuration` at module level. During
startup, `airflow.configuration` initializes secrets backends, which in turn
import `airflow.models.Connection`. This creates a circular import that can
cause `ImportError: Module "airflow.models.connection" does not define a
"Connection"` when the import is re-entered before the `Connection` class is
fully defined. The fix moves the import to the only method that uses it
(`get_connection_from_secrets`), keeping runtime behavior identical while
eliminating the import-time recursion.
