Gautam-Bharadwaj opened a new pull request, #63664: URL: https://github.com/apache/airflow/pull/63664
The `timeout_with_traceback` context manager in `airflow.utils.db` uses `signal.SIGALRM` to raise a `TimeoutException`. However, `signal.SIGALRM` does not exist on Windows, causing an `AttributeError`. Furthermore, even on Unix, `signal.signal()` can only be called from the main thread, raising a `ValueError` inside worker threads. This completely breaks logic wrapped in this context in non-standard environments. This PR adds safe exception handling around the signal initialization. If `signal.SIGALRM` fails due to OS constraints or thread context, it logs a warning and proceeds gracefully as a no-op timeout, instead of crashing the process. --- ##### Was generative AI tooling used to co-author this PR? - [ ] Yes -- This is an automated message from the Apache Git Service.
