Addresses two critical issues in the auto-save system: 1. Memory Leak (#1): Cache entries were accumulating indefinitely after auto-save operations. Added cleanup in handleAfterSave callback to delete cache entries and clear dirty state after successful saves. 2. Silent Auto-Save Skips (#2): When users switched files during the auto-save debounce period, saves were silently skipped with no visibility. Added console logging to track when auto-saves are cancelled due to file switching. Changes: - App.tsx: Clear cache and dirty state in handleAfterSave after success - App.tsx: Add setFileDirty to useCallback dependency array - useFileContent.ts: Log auto-save skips when file path changes This ensures memory doesn't grow unbounded during long editing sessions and provides debugging visibility for auto-save behavior.

This commit fixes both critical auto-save issues based on debug log analysis: ## Issue #1: External Edit Warnings - Debounce Window Too Short **Root cause (from logs):** ``` [SaveTracking] Age: 2164 ms [SaveTracking] Debounce window: 2000 ms [SaveTracking] Result: FALSE (too old) ``` File watcher events on macOS arrive 2000-2500ms after save completion, missing the 2000ms window by 19-164ms. **Fix:** - Increased FILE_WATCHER_DEBOUNCE_MS from 2000ms → 3000ms - Location: src/shared/config/timing.ts:21 - This accounts for macOS filesystem latency and disk I/O buffering ## Issue #2: Cursor Jumping - setContent Called on Every Keystroke **Root cause (from logs):** ``` [EditorComponent] hasContentChanged: true [EditorComponent] content length: 343 [EditorComponent] prev content length: 342 [EditorComponent] CALLING setContent (WYSIWYG content change) ``` Every keystroke triggered: user types → onUpdate → updateContent → content prop changes → EditorComponent useEffect sees hasContentChanged=true → calls setContent → cursor resets. This is a circular update problem: 1. User types in TipTap editor 2. TipTap fires onUpdate with new content 3. handleUpdate calls updateContent, updating React state 4. EditorComponent re-renders with new content prop 5. useEffect detects content change and calls setContent ← **CURSOR RESET** 6. Editor now has same content but cursor position is lost **Fix:** - Added isUserEditingRef flag to track when content change originates from user typing - wrappedOnUpdate sets flag=true, calls onUpdate, resets flag after 10ms - useEffect checks flag and skips setContent if user is actively editing - Location: src/renderer/components/Editor/EditorComponent.tsx:157-248 **How it works:** 1. User types → onUpdate fires 2. wrappedOnUpdate sets isUserEditingRef.current = true 3. Calls parent's onUpdate → content state updates 4. useEffect runs, sees isUserEditingRef = true 5. Skips setContent call → cursor preserved 6. Flag resets after 10ms to allow external updates **Files modified:** - src/shared/config/timing.ts: Increase debounce window to 3000ms - src/renderer/components/Editor/EditorComponent.tsx: Add isUserEditingRef guard Resolves cursor jumping on every keystroke and false external edit warnings.

* fix: address high/medium priority auto-save issues High Priority Fixes: - Fix race condition in updateContent auto-save by adding contentRef to track latest content synchronously, preventing data loss from rapid typing - Add clearAutoSaveTimer() to saveFile method to prevent duplicate saves when user manually saves (Cmd+S) Medium Priority Fixes: - Improve blur handler save tracking consistency by moving trackSaveStart before write operation and adding proper trackSaveEnd on all code paths - Move module-level state to component refs (activeSaves Map and cleanup interval) and convert tracking functions to useCallback hooks to prevent potential HMR issues and memory leaks All tests passing (13/13 in useFileContent.test.ts). * fix: resolve auto-save cursor jump and false external edit warnings This commit fixes two critical issues in the auto-save implementation: 1. **Cursor jumping during auto-save** - Root cause: handleContentLoaded was calling updateContent() even when content hadn't changed, triggering unnecessary re-renders - Fix: Added content comparison in handleContentLoaded to only update when content actually differs - Location: src/renderer/App.tsx:204-216 2. **False "external edit" warnings** - Root cause 1: Path variable mismatch (currentActivePath vs fileContent.filePath) - Root cause 2: trackSaveEnd being called too early (50ms), before file watcher events arrived (500-2000ms typical on macOS) - Fix: Use consistent path variable (fileContent.filePath) and remove all trackSaveEnd calls to let timestamps persist for full 2000ms window - Location: src/renderer/App.tsx:488-494, 192-196, 454-469 **Architecture changes:** - Removed module-level save tracking functions (trackSaveStart, isSaveActive, trackSaveEnd) in favor of component-level implementations - Removed module-level activeSaves Map - now managed per-component instance - Simplified save tracking: timestamps persist for full debounce window, cleaned up eagerly when map exceeds 50 entries - Exported hashString from useEditor for content comparison **Files modified:** - src/renderer/App.tsx: Save tracking refactor, cursor jump fix - src/renderer/components/Editor/EditorComponent.tsx: Minor documentation - src/renderer/hooks/useEditor.ts: Export hashString utility Fixes issues reported in PR review where cursor would jump to end of document during auto-save and users would see spurious "file modified externally" warnings for their own saves. * fix: add onBeforeSave callback and prevent spurious setContent calls This commit fixes two critical auto-save issues: 1. **External edit warnings for auto-saves** (CRITICAL BUG FIX) - Root cause: Auto-save in useFileContent.ts was NOT calling onBeforeSave(), so trackSaveStart() never executed for auto-saves - Fix: Added onBeforeSave?.() call at line 331 before initiating save - Impact: File watcher now correctly ignores auto-save events via timestamp checking in isSaveActive() - Location: src/renderer/hooks/useFileContent.ts:330-331 2. **Cursor jumping during auto-save** (CRITICAL BUG FIX) - Root cause: EditorComponent useEffect was calling setContent even when neither viewMode nor content had changed, likely due to state updates from auto-save triggering effect re-evaluation - Fix: Added early return when !isViewModeTransition && !hasContentChanged to prevent any setContent calls when nothing actually changed - Impact: Cursor position preserved during auto-save - Location: src/renderer/components/Editor/EditorComponent.tsx:210-216 **Technical details:** Auto-save flow (before fix): 1. User types → updateContent() called → auto-save timer starts (300ms) 2. Timer fires → writeFile() called → file saved 3. State updated: isDirty=false, originalContent updated 4. ❌ onBeforeSave NOT called → trackSaveStart never executed 5. File watcher event arrives 500-2000ms later 6. isSaveActive(filePath) returns false → shows external edit warning Auto-save flow (after fix): 1. User types → updateContent() called → auto-save timer starts (300ms) 2. Timer fires → onBeforeSave() called → trackSaveStart() executed 3. writeFile() called → file saved 4. State updated: isDirty=false, originalContent updated 5. File watcher event arrives 500-2000ms later 6. ✅ isSaveActive(filePath) returns true → event ignored Cursor jump flow (before fix): 1. Auto-save completes → state updates (isDirty, saving, originalContent) 2. EditorComponent re-renders with same content prop 3. useEffect runs because dependencies include viewMode, editor, content 4. hasContentChanged = false BUT useEffect still processes 5. ❌ Calls setContent anyway → cursor resets Cursor jump flow (after fix): 1. Auto-save completes → state updates (isDirty, saving, originalContent) 2. EditorComponent re-renders with same content prop 3. useEffect runs because dependencies include viewMode, editor, content 4. ✅ Early return: !isViewModeTransition && !hasContentChanged 5. No setContent call → cursor position preserved **Files modified:** - src/renderer/hooks/useFileContent.ts: Add onBeforeSave() call, add to deps - src/renderer/components/Editor/EditorComponent.tsx: Add early return guard Resolves cursor jumping and false external edit warnings reported in testing. * debug: add comprehensive logging for auto-save cursor jump investigation Added detailed console logging throughout the auto-save and content sync flow to diagnose why fixes aren't working: **Auto-save logging (useFileContent.ts):** - Log when auto-save starts, file path, content length - Log when onBeforeSave callback is called - Log file write success/failure - Log when onAfterSave is called **Save tracking logging (App.tsx):** - trackSaveStart: Log file path normalization and timestamp storage - isSaveActive: Log file path, timestamp lookup, age calculation, result - handleBeforeSave: Log when called and current file path - File watcher: Log all events, path comparisons, isSaveActive checks **Editor sync logging (EditorComponent.tsx):** - Log every useEffect trigger with view mode and content change status - Log when early return prevents sync - Log every setContent call with stack trace - Log hash comparisons when checking if content actually changed **Content loaded logging (App.tsx):** - Log when handleContentLoaded is called - Log content lengths and isDirty state - Log when updateContent is called (causes cursor jump) - Add stack traces to trace call origin This will reveal: 1. Whether onBeforeSave is actually being called during auto-save 2. Whether trackSaveStart receives the correct file path 3. Whether isSaveActive returns true/false and why 4. What triggers setContent during auto-save 5. Whether handleContentLoaded is being called unexpectedly Next step: Test auto-save scenario and analyze console output. * fix: prevent cursor jump and extend debounce window for macOS This commit fixes both critical auto-save issues based on debug log analysis: ## Issue #1: External Edit Warnings - Debounce Window Too Short **Root cause (from logs):** ``` [SaveTracking] Age: 2164 ms [SaveTracking] Debounce window: 2000 ms [SaveTracking] Result: FALSE (too old) ``` File watcher events on macOS arrive 2000-2500ms after save completion, missing the 2000ms window by 19-164ms. **Fix:** - Increased FILE_WATCHER_DEBOUNCE_MS from 2000ms → 3000ms - Location: src/shared/config/timing.ts:21 - This accounts for macOS filesystem latency and disk I/O buffering ## Issue #2: Cursor Jumping - setContent Called on Every Keystroke **Root cause (from logs):** ``` [EditorComponent] hasContentChanged: true [EditorComponent] content length: 343 [EditorComponent] prev content length: 342 [EditorComponent] CALLING setContent (WYSIWYG content change) ``` Every keystroke triggered: user types → onUpdate → updateContent → content prop changes → EditorComponent useEffect sees hasContentChanged=true → calls setContent → cursor resets. This is a circular update problem: 1. User types in TipTap editor 2. TipTap fires onUpdate with new content 3. handleUpdate calls updateContent, updating React state 4. EditorComponent re-renders with new content prop 5. useEffect detects content change and calls setContent ← **CURSOR RESET** 6. Editor now has same content but cursor position is lost **Fix:** - Added isUserEditingRef flag to track when content change originates from user typing - wrappedOnUpdate sets flag=true, calls onUpdate, resets flag after 10ms - useEffect checks flag and skips setContent if user is actively editing - Location: src/renderer/components/Editor/EditorComponent.tsx:157-248 **How it works:** 1.

Flag resets after 10ms to allow external updates **Files modified:** - src/shared/config/timing.ts: Increase debounce window to 3000ms - src/renderer/components/Editor/EditorComponent.tsx: Add isUserEditingRef guard Resolves cursor jumping on every keystroke and false external edit warnings. * fix: track editor-originated content to prevent cursor jump on first keystroke The previous isUserEditingRef approach with setTimeout didn't work because: - React state updates propagate synchronously - useEffect runs before the setTimeout (10ms) fires - Cursor still jumped on first character typed New approach: - Track the last content that originated from the editor in lastEditorContentRef - When content prop changes, check if it matches lastEditorContentRef - If it matches, skip setContent() call - this content came FROM the editor - Only call setContent() for external content changes (file loads, etc.) This prevents the circular flow: 1. User types 'x' → onUpdate fires with content 2. wrappedOnUpdate stores content in lastEditorContentRef 3. Parent state updates with content 4. EditorComponent re-renders with new content prop 5. useEffect checks: content === lastEditorContentRef.current 6. TRUE → skip setContent() → cursor preserved ✓ Location: src/renderer/components/Editor/EditorComponent.tsx:157-244 This fix specifically addresses the issue where cursor jumps to end of file immediately after typing the first character. * fix: prevent cursor jump on typing by tracking editor-originated content Root cause: useEditor's useEffect was calling setContent() on EVERY keystroke because the markdown content coming back via props had a different hash than the previously converted markdown (TipTap's HTML→markdown conversion isn't perfectly stable). Fix: - Track markdown sent via onUpdate in lastOnUpdateContentRef - Skip setContent() if incoming content matches lastOnUpdateContentRef - This breaks the circular update loop: type → onUpdate → parent state → useEffect → setContent → cursor reset Also increased FILE_WATCHER_DEBOUNCE_MS from 4000ms to 5000ms since macOS file watcher events can arrive at 4025ms (25ms over the window). Removed all debug logging added during investigation. * refactor: implement PR #25 review recommendations for auto-save Addresses all feedback from PR #25 code review to improve auto-save robustness, error handling, and code quality: - Add user-facing error toast for auto-save failures via onError callback - Add race condition check in auto-save timer to prevent wrong-file writes - Remove unused _success parameter from handleAfterSave callback - Clean up eslint-disable comment with better explanation about ref stability - Document FILE_WATCHER_DEBOUNCE_MS UX tradeoff for collaborative editing These changes improve user experience by surfacing auto-save errors and preventing edge case bugs where rapid file switching could cause content to be saved to the wrong file.
