Summary by CodeRabbit

• Bug Fixes
  • Down-alert timing now stays within a safe range when configured with extremely large, negative, or non-numeric values, preventing invalid cutoff calculations.
• Tests
  • Added coverage for extreme and negative down-alert settings and their resulting notification cutoffs.

Walkthrough

The notification code now converts the configured down-alert duration to an integer and clamps it between zero and 100 years before calculating the cutoff. Tests cover extreme and negative values, and the clearing-method docstring describes the cutoff used for notification selection.

Changes: Device Down cutoff

Layer / File(s)	Summary
Bound and apply alert-down duration server/messaging/reporting.py, server/models/notification_instance.py, test/backend/test_notification_down_clear_timezone.py	A new helper converts the configured duration and clamps it to the supported range. get_notifications() uses the bounded value. The docstring identifies the cutoff used for event selection, and tests check very large and negative settings.

test/backend/test_notification_down_clear_timezone.py: 1

306-315: Trivial · Functional Correctness · Quick win

Assert the 100-year cutoff for the huge setting.

The current assertion only checks that the cutoff is earlier than the current time. A regression that maps an above-maximum value to a zero-minute cutoff would still pass. Assert that the cutoff is approximately MAX_ALERT_DOWN_MINUTES before the current time.

Suggested fix

-from messaging.reporting import get_notifications
+from messaging.reporting import MAX_ALERT_DOWN_MINUTES, get_notifications
...
     def test_huge_value_does_not_raise(self):
         """A value too large for timedelta/datetime must be bounded, not raise
         OverflowError."""
+        before = timeNowUTC(as_string=False)
         cutoff = self._run_get_notifications("999999999999999")
-        self.assertLess(cutoff, timeNowUTC(as_string=False))
+        after = timeNowUTC(as_string=False)
+        max_delta = timedelta(minutes=MAX_ALERT_DOWN_MINUTES)
+        self.assertGreaterEqual(cutoff, before - max_delta - timedelta(seconds=1))

Strengthen `test_huge_value_does_not_raise` to verify the cutoff reflects the
configured maximum window, not merely that it is in the past. Capture the
current time before and after `_run_get_notifications`, then assert the cutoff
falls within the elapsed-time-tolerant bounds for `MAX_ALERT_DOWN_MINUTES`
before now, importing that constant if needed.
