Implement 5 medium/low priority improvements identified in systematic review: UX IMPROVEMENTS: - Notify existing critical alerts when activating from pending_review state Previously: critical alerts during observation window would never notify Now: users receive notifications for active critical alerts after activation Implementation: Added NotifyExistingAlert() method and logic in ActivateAlerts() PERFORMANCE OPTIMIZATIONS: - Replace per-alert cleanup goroutines with periodic batch cleanup Prevents spawning 1000s of goroutines during alert flapping recentlyResolved entries now cleaned up once per minute instead of 1 goroutine per alert - Simplify GetActiveAlerts() implementation Removed intermediate map copy, holds lock slightly longer but operation is fast Cleaner code with reduced memory allocation CONFIGURATION VALIDATION: - Validate timezone in quiet hours configuration Invalid timezones now disable quiet hours with error log instead of silent fallback Prevents unexpected behavior when timezone is typo'd or invalid GRACEFUL SHUTDOWN: - Add 100ms delay in Stop() for background goroutine cleanup Reduces risk of state corruption during shutdown Allows escalation checker and periodic save to exit cleanly Technical details: - internal/alerts/alerts.go: Added NotifyExistingAlert(), optimized cleanup patterns - internal/api/alerts.go: Enhanced ActivateAlerts() to notify existing critical alerts - Removed ~20 lines of goroutine spawning code - Added periodic cleanup for recentlyResolved map - All changes preserve backward compatibility Testing: Verified compilation with 'go build -o /dev/null ./...' |
