Catch Of Control Flow Exception (ARCH2168)

Key python.logging.catch-control-flow · Severity warning · Category logging

Catching framework/runtime exceptions like KeyboardInterrupt or SystemExit that should propagate breaks cancellation and shutdown behavior. These exceptions let the application stop cleanly.

Incorrect

try:
    run_worker()
except BaseException:
    logger.error("Worker stopped")

Correct

try:
    run_worker()
except Exception:
    logger.exception("Worker error")

Fix

Catch Exception rather than BaseException; let cancellation and shutdown exceptions propagate.
