From fd21f62b8a56643a9cca8f20ecc8809ce329631d Mon Sep 17 00:00:00 2001 From: Shivang Date: Tue, 27 Jan 2026 13:02:21 -0800 Subject: [PATCH 1/8] feat: Add global hotkey to summon BossTerm windows MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements system-wide hotkeys to summon specific BossTerm windows from anywhere, similar to iTerm2's hotkey window feature. Features: - Window-specific hotkeys: Modifiers+1 for window 1, Modifiers+2 for window 2, etc. - Cross-platform support: Windows (Win32 API), macOS (Carbon API), Linux (X11) - Configurable modifiers: Ctrl, Alt/Option, Shift, Win/Command - Hotkey hint displayed in title bar (custom) or as overlay (native) - Settings UI in Settings → Global Hotkey - Auto-migration of settings for existing users Default hotkey: Ctrl+1, Ctrl+2, etc. (configurable) Closes #241 Generated with [Claude Code](https://claude.com/claude-code) --- .../kotlin/ai/rever/bossterm/app/Main.kt | 106 ++-

Linux keycode matching: Extract actual keycode from XEvent instead of always triggering first window 2. Thread initialization race: Use CountDownLatch to ensure platform resources are initialized before registration 3. Resource leak prevention: Increase shutdown timeout, add interrupt checks, ensure cleanup in all code paths 4. Error status updates: Set FAILED status on all error paths **High Priority Fixes:** 5. Platform detection: Replace raw System.getProperty() with ShellCustomizationUtils for consistency 6. Linux performance: Reduce polling interval from 50ms to 10ms (~5ms avg latency vs ~25ms) 7. Windows thread safety: Reset winThreadId only after thread stops 8.

Race condition in initialization: Move startGlobalHotKeyManager() inside application block after initial window creation to prevent empty window list and duplicate window creation 2. Memory leak: Clear macOS callback references in stop() to prevent leaks 3. Thread safety: Add @Volatile to isRunning flag for proper visibility across threads 4. Hard-coded X11 offset: Replace architecture-dependent getInt(84) with proper Structure.newInstance() to support 32-bit, ARM, and non-standard X11 5. Window number reuse: Set up WindowManager callbacks to properly track window lifecycle and re-register hotkeys when numbers are reused **High Priority Fixes:** 6. Error logging: Add proper error messages in WindowVisibilityController for debugging 7. Unsafe latch timeout: Check CountDownLatch.await() return value and abort if initialization times out 8.

Thread-unsafe collections: Use Collections.synchronizedSet/Map for registeredWindows, macHotKeyRefs, and linuxKeycodes to prevent race conditions during concurrent access 2. macOS CFString memory leak: Remove premature nulling in stop() to prevent race where CFString leaks if cleanupMacOS() runs after macRunLoopMode is set to null 3. Reflection error messages: Add specific catch for InaccessibleObjectException with clear guidance about required --add-opens JVM flag **High Priority Fixes:** 4. Linux partial registration: Mark as FAILED if <50% hotkeys register, provide detailed feedback about partial registrations (e.g., 4/9) 5. Consistent status updates: Verified all event loop error handlers update _registrationStatus.value (already complete from previous round) 6. Null checks on API instances: Verified smart casting after null checks provides adequate safety **Medium Priority Fixes:** 7.

XKeyEvent Memory Leak: Eliminated Structure.newInstance() allocation on every KeyPress event by reading keycode directly from native memory 2. SecurityException Handling: Added specific catch block for SecurityManager reflection denial with clear user guidance 3. macRunLoopMode Cleanup Race: Fixed race condition by capturing pointer locally before CFRelease to prevent concurrent access issues 4. Success Threshold Documentation: Extracted LINUX_SUCCESS_THRESHOLD constant with detailed rationale and improved error messages 5. Window Number Validation: Added bounds checking (1-9) in WindowManager callbacks to prevent invalid registrations 6. Thread Interruption Preservation: Save and restore caller's interrupt status in stop() method to prevent status loss All changes compile successfully and improve thread safety, resource management, and error handling in the global hotkey system.

They remain enabled by default on Windows where conflicts are less common. Rationale: - Linux DEs (GNOME, KDE) often use Ctrl+Alt+1-9 for workspace switching - macOS Mission Control uses similar key combinations - Windows has fewer system-wide hotkey conflicts - Better user experience to opt-in after understanding the feature Users can enable in Settings → Global Hotkey and configure custom modifier combinations to avoid conflicts.
