Fixed race conditions and loading problems when users click folders
or navigation buttons too quickly.
## Problems Identified:
### 1. Race Conditions in Path Changes
**Issue**: Fast clicking folders/back button caused multiple simultaneous requests
- useEffect triggered on every currentPath change
- No debouncing for path changes (only for manual refresh)
- Multiple loadDirectory() calls executed concurrently
- Later responses could overwrite earlier ones
### 2. Concurrent Request Conflicts
**Issue**: loadDirectory() had basic isLoading check but insufficient protection
- Multiple requests could run if timing was right
- No tracking of which request was current
- Stale responses could update UI incorrectly
### 3. Missing Request Cancellation
**Issue**: No way to cancel outdated requests when user navigates rapidly
- Old requests would complete and show wrong directory
- Confusing UI state when mixed responses arrived
## Technical Solution:
### **Path Change Debouncing**
```typescript
// Added 150ms debounce specifically for path changes
const debouncedLoadDirectory = useCallback((path: string) => {
if (pathChangeTimerRef.current) {
clearTimeout(pathChangeTimerRef.current);
}
pathChangeTimerRef.current = setTimeout(() => {
if (path !== lastPathChangeRef.current && sshSessionId) {
loadDirectory(path);
}
}, 150);
}, [sshSessionId, loadDirectory]);
```
### **Request Race Condition Protection**
```typescript
// Track current loading path for proper cancellation
const currentLoadingPathRef = useRef<string>("");
// Enhanced concurrent request prevention
if (isLoading && currentLoadingPathRef.current !== path) {
console.log("Directory loading already in progress, skipping:", path);
return;
}
```
### **Stale Response Handling**
```typescript
// Check if response is still relevant before updating UI
if (currentLoadingPathRef.current !== path) {
console.log("Directory load canceled, newer request in progress:", path);
return; // Discard stale response
}
```
## Flow Improvements:
**Before (Problematic):**
1. User clicks folder A → currentPath changes → useEffect → loadDirectory(A)
2. User quickly clicks folder B → currentPath changes → useEffect → loadDirectory(B)
3. Both requests run concurrently
4. Response A or B arrives randomly, wrong folder might show
**After (Fixed):**
1. User clicks folder A → currentPath changes → debouncedLoadDirectory(A)
2. User quickly clicks folder B → currentPath changes → cancels A timer → debouncedLoadDirectory(B)
3. Only request B executes after 150ms
4. If A somehow runs, its response is discarded as stale
## User Experience:
✅ Rapid folder navigation works smoothly
✅ Back button rapid clicking handled properly
✅ No more loading wrong directories
✅ Proper loading states maintained
✅ No duplicate API requests
✅ Responsive feel with 150ms debounce (fast enough to feel instant)
The file manager now handles rapid user interactions gracefully without
race conditions or loading the wrong directory content.

Fixed the brief jarring flash between SSH connection and file list display:
## Problem
During file manager connection process:
1. SSH connection completes → setIsLoading(false)
2. Brief empty/intermediate state displayed (jarring flash)
3. useEffect triggers → setIsLoading(true) again
4. Directory loads → setIsLoading(false)
5. Files finally displayed
This created a jarring user experience with double loading states.
## Root Cause
- initializeSSHConnection() only handled SSH connection
- File directory loading was handled separately in useEffect
- Gap between connection completion and directory loading caused UI flash
## Solution
**Unified Connection + Directory Loading:**
- Modified initializeSSHConnection() to load initial directory immediately after SSH connection
- Added initialLoadDoneRef to prevent duplicate loading in useEffect
- Loading state now remains true until both connection AND directory are ready
**Technical Changes:**
- SSH connection + initial directory load happen atomically
- useEffect skips initial load, only handles path changes
- No more intermediate states or double loading indicators
## Flow Now:
1. setIsLoading(true) → "Connecting..."
2. SSH connection establishes
3. Initial directory loads immediately
4. setIsLoading(false) → Files displayed seamlessly
**User Experience:**
✅ Smooth single loading state until everything is ready
✅ No jarring flashes or intermediate states
✅ Immediate file display after connection
✅ Maintains proper loading states for path changes

Added missing translation key for database security settings:
Problem:
- AdminSettings.tsx used t("admin.encryptionEnabled")
- Translation key was missing from both English and Chinese files
- Caused missing text in database security encryption status display
Solution:
- Added "encryptionEnabled": "Encryption Enabled" to English translations
- Added "encryptionEnabled": "加密已启用" to Chinese translations
- Maintains consistency with existing encryption-related translations
Files updated:
- src/locales/en/translation.json
- src/locales/zh/translation.json
Now the database security section properly displays encryption status
with correct i18n support in both languages.

Fixed "ReferenceError: t is not defined" when creating new files/folders:
Problem:
- CreateIntentGridItem and CreateIntentListItem components used t() function
- But neither component had useTranslation hook imported
- Caused runtime error when trying to create new files or folders
Solution:
- Added const { t } = useTranslation(); to both components
- Fixed hardcoded English text in CreateIntentListItem placeholder
- Now uses proper i18n translation keys for all UI text
Changes:
- CreateIntentGridItem: Added useTranslation hook
- CreateIntentListItem: Added useTranslation hook + fixed placeholder text
- Both components now properly use t('fileManager.folderName') and t('fileManager.fileName')
Now file/folder creation works without console errors and supports i18n.

Fixed two critical database issues causing user creation errors and data loss:
## Issue 1: Lazy Encryption Migration Error
**Problem**: TypeError: Cannot read properties of undefined (reading 'db')
**Root Cause**: AuthManager called getSqlite() before database initialization
**Solution**: Added databaseReady promise await before accessing SQLite instance
Changes in auth-manager.ts:
- Import and await databaseReady promise before getSqlite() call
- Ensures database is fully initialized before migration attempts
- Prevents "SQLite not initialized" errors during user login
## Issue 2: Data Loss After Backend Restart
**Problem**: All user data wiped after backend restart
**Root Cause**: Database saves were skipped when file encryption disabled
**Solution**: Added fallback to unencrypted SQLite file persistence
Changes in database/db/index.ts:
- Modified saveMemoryDatabaseToFile() to handle encryption disabled scenario
- Added unencrypted SQLite file fallback to prevent data loss
- Added data directory creation to ensure save path exists
- Enhanced logging to track save operations and warnings
## Technical Details:
- saveMemoryDatabaseToFile() now saves data regardless of encryption setting
- Encrypted: saves to .encrypted file (existing behavior)
- Unencrypted: saves to .sqlite file (new fallback)
- Ensures data persistence in all configurations
- Maintains 15-second auto-save and real-time trigger functionality
These fixes ensure:
✅ User creation works without backend errors
✅ Data persists across backend restarts
✅ Lazy encryption migration completes successfully
✅ Graceful handling of encryption disabled scenarios

Root cause: Duplicate handleFileOpen function definitions caused symlinks
to be treated as regular files instead of navigating to their targets.
Problem:
- Line 575: Correct implementation with symlink handling
- Line 1401: Incorrect duplicate that overrode the correct function
- Double-clicking symlinks opened them as files instead of following links
Solution:
- Removed duplicate handleFileOpen function (lines 1401-1436)
- Preserved correct implementation with symlink navigation logic
- Added recordRecentFile call for consistency
Now symlinks properly:
- Navigate to target directories when they point to folders
- Open target files when they point to files
- Use identifySSHSymlink backend API for resolution

Fixed WebSocket connection issue where SSH terminals couldn't connect
despite correct credentials. Root cause was port mismatch - terminals
were trying to connect to port 8081 while SSH service runs on 8082.
Changes:
- Desktop Terminal: Updated WebSocket URL to use port 8082
- Mobile Terminal: Updated WebSocket URL to use port 8082
- File Manager continues using port 8081 for HTTP API (unchanged)
This ensures all SSH terminal connections route to the correct service port.

Replace all Chinese comments with English equivalents while preserving:
- Technical meaning and Linus-style direct tone
- Code structure and functionality
- User-facing text in UI components
Backend files cleaned:
- All utils/ TypeScript files
- Database routes and operations
- System architecture comments
- Field encryption documentation
All backend code now uses consistent English comments.
Problems Fixed:
• Hardcoded default JWT secret - global security disaster for open-source
• Over-complex "system master key" layer that solved no real threats
• Empty UserCrypto database methods breaking authentication
Linus-style Solution:
• Delete hardcoded keys completely - every instance gets unique random key
• Implement proper key loading priority: ENV → File → DB → Generate
• Complete UserCrypto implementation for KEK/DEK storage
• Automatic generation on first startup - zero configuration required
Security Improvements:
• Open-source friendly: Each instance has independent JWT secret
• Production ready: JWT_SECRET environment variable support
• Developer friendly: Auto-generation with file/database persistence
• Container friendly: Volume mount for .termix/jwt.key persistence
Architecture Simplification:
• Deleted complex system master key encryption layer
• Direct JWT secret storage - simple and effective
• File-first storage for performance, database fallback
• Comprehensive test suite validates all security properties
Testing:
• All 7 security tests pass including uniqueness verification
• No hardcoded secrets, proper environment variable priority
• File and database persistence working correctly
This eliminates the critical vulnerability where all Termix instances
would share the same JWT secret, making authentication meaningless.

This commit removes 500+ lines of fake "migration" code that admitted it couldn't
do what it claimed to do. Following Linus principles: if code can't deliver on
its promise, delete it rather than pretend.
Changes:
- DELETE: security-migration.ts (448 lines of fake migration logic)
- DELETE: SECURITY_REFACTOR_PLAN.md (outdated documentation)
- DELETE: /encryption/migrate API endpoint (non-functional)
- REPLACE: Complex "migration" with simple 3-line legacy user setup
- CLEAN: Remove all migration imports and references
The new approach is honest: legacy users get encryption setup on first login.
No fake progress bars, no false promises, no broken complexity.
Good code doesn't pretend to do things it can't do.
Major improvements:
- Replaced 226 Chinese comments with clear English equivalents across 16 files
- Backend security files: Complete English documentation for KEK-DEK architecture
- Frontend drag-drop hooks: Full English comments for file operations
- Database routes: English comments for all encryption operations
- Removed V1/V2 version identifiers, unified to single secure architecture
Files affected:
- Backend (11 files): Security session, user/system key managers, encryption operations
- Frontend (5 files): Drag-drop functionality, API communication, type definitions
- Deleted obsolete V1 security files: encryption-key-manager, database-migration
Benefits:
- International developer collaboration enabled
- Professional coding standards maintained
- Technical accuracy preserved for all cryptographic terms
- Zero functional impact, TypeScript compilation and tests pass

Removes all remaining hardware fingerprint validation logic to fix system
startup errors and improve cross-hardware compatibility.
Key changes:
- Remove hardware compatibility checks from database-file-encryption.ts
- Remove backup restore hardware validation from database.ts
- Remove database initialization hardware checks from db/index.ts
- Delete hardware-fingerprint.ts module entirely
- Update migration files to use fixed identifiers
Fixes "wmic is not recognized" and "Hardware fingerprint mismatch" errors
that were preventing system startup and database operations.
Problem Analysis:
- Fixed salt disaster: All same-type fields used identical encryption keys
- Exposed user password KEK protection as completely fake security theater
- System generated random password while claiming user password protection
- 500+ lines of complex migration logic for non-existent backward compatibility
Linus-Style Solutions Applied:
✅ "Delete code > Write code" - Removed 1167 lines of fake complexity
✅ "Complexity is evil" - Eliminated all special cases and migration paths
✅ "Practical solutions" - System auto-starts with secure random keys
✅ "Good taste" - Each field gets unique random salt, true data isolation
Core Changes:
• FIXED: Each encrypted field now gets unique random salt (no more shared keys)
• DELETED: MasterKeyProtection.ts - entire fake KEK protection system
• DELETED: encryption-test.ts - outdated test infrastructure
• SIMPLIFIED: User password = authentication only (honest design)
• SIMPLIFIED: Random master key = data protection (more secure than user passwords)
Security Improvements:
- Random keys have higher entropy than user passwords
- Simpler system = smaller attack surface
- Honest design = clear user expectations
- True field isolation = breaking one doesn't compromise others
Before: Break 1 password → Get all passwords of same type
After: Each field independently encrypted with unique keys
"Theory and practice sometimes clash. Theory loses. Every single time." - Linus
This removes theoretical security theater and implements practical protection.
VULNERABILITY ELIMINATED: Hardware fingerprint dependency created a false
sense of security while actually making attacks easier due to predictable
hardware information.
Core Changes:
- MasterKeyProtection: Replace hardware fingerprint with user password + random salt
- EncryptionKeyManager: Accept userPassword parameter for KEK derivation
- DatabaseEncryption: Pass userPassword through initialization chain
- Version bump: v1 (hardware) -> v2 (password-based) with migration detection
Security Improvements:
- TRUE RANDOMNESS: 256-bit random salt instead of predictable hardware info
- STRONGER KEK: PBKDF2 100,000 iterations with user password + salt
- CROSS-DEVICE SUPPORT: No hardware binding limitations
- FORWARD SECRECY: Different passwords generate completely different encryption
Technical Details:
- Salt generation: crypto.randomBytes(32) for true entropy
- KEK derivation: PBKDF2(userPassword, randomSalt, 100k, 32, sha256)
- Legacy detection: Throws error for v1 hardware-based keys
- Testing: New password-based KEK validation test
This eliminates the fundamental flaw where "security" was based on
easily obtainable system information rather than true cryptographic
randomness. Hardware fingerprints provided no actual security benefit
while creating deployment and migration problems.

SECURITY FIX: Replace dangerous JWT_SECRET environment variable with
encrypted database storage using hardware-bound KEK protection.
Changes:
- EncryptionKeyManager: Add JWT secret management with AES-256-GCM encryption
- All route files: Eliminate process.env.JWT_SECRET dependencies
- Database server: Initialize JWT secret during startup with proper error handling
- Testing: Add comprehensive JWT secret management test coverage
- API: Add /encryption/regenerate-jwt endpoint for key rotation
Technical implementation:
- JWT secrets now use same protection as SSH keys (hardware fingerprint binding)
- 512-bit JWT secrets generated via crypto.randomBytes(64)
- KEK-protected storage prevents cross-device secret migration
- No backward compatibility for insecure environment variable approach
This eliminates the critical security flaw where JWT tokens could be
forged using the default "secret" value, achieving uniform security
architecture with no special cases.
