Critical Timer Fix - Version 1.1.3

What’s Fixed in Deep Focus v1.1.3

This update addresses a critical issue where the pomodoro timer would freeze after 1 second on Windows and Linux systems, while working correctly on macOS.

Problem Resolved

  • Timer Freezing: Timer would stop after 1 second and show “Service worker (Inactive)” on Windows/Linux
  • Platform Inconsistency: Extension worked on macOS but failed on other operating systems
  • Service Worker Inactivity: Chrome’s service worker would go idle, causing timer alarms to stop

Technical Solution

  • Aggressive Keep-Alive System: Implemented multiple alarm mechanisms to prevent service worker from going inactive
  • Cross-Platform Timing: Added precise timestamp-based calculations instead of interval-based timing
  • Client-Side Fallback: Enhanced popup with real-time timer calculation for smooth countdown
  • Backup Alarms: Multiple redundant alarms ensure timer completion even if primary alarm fails
  • State Persistence: Improved state saving to survive service worker restarts

Implementation Details

  • 6-Second Keep-Alive Alarms: Prevents service worker inactivity on problematic platforms
  • Timestamp-Based Calculation: Uses precise start timestamps instead of cumulative intervals
  • Multiple Redundancy: Primary tick, backup completion, and heartbeat alarms
  • Enhanced Error Recovery: Automatic alarm recreation if any component fails

This fix ensures reliable timer operation across all Chrome-supported operating systems and resolves the service worker inactivity issue that primarily affected Windows and Linux users.
