🐛 Critical Debugging Fixes:
- Safe Wrapper System:
Error Handling: Every UI callback is wrapped in a safe error handler
Exception Catching: Prevents crashes from individual function failures
User Feedback: Shows error messages instead of crashing
Graceful Degradation: Continues working even when some features fail
- UI Initialization Fixes:
Proper Initialization Order: Variables initialized before UI creation
Component References: All UI components properly stored as instance variables
Grid Layout Fixes: Proper column spanning and weight configuration
Conditional UI: Features only appear if required modules are available
- Memory Management:
Safe Tree Operations: Proper checking before tree operations
Resource Cleanup: Proper cleanup of connections and resources
Thread Safety: Safe UI updates from background threads
Null Checks: Extensive null checking for all UI components
- Error Recovery:
Partial Failure Handling: Continues working even if some profiles/extensions fail
Backup Validation: Ensures backups are created before destructive operations
Status Reporting: Clear feedback about what succeeded and what failed
Rollback Capability: Can recover from failed operations
- Cross-Platform Robustness:
Path Safety: Safe path construction across different operating systems
Process Detection: Robust Chrome process detection with fallbacks
File Access: Safe file operations with proper encoding
Exception Handling: Platform-specific error handling
✨ Enhanced Debugging Features:
- Comprehensive Status Logging:
pythondef log_status(self, message):
"""Safe status logging with fallbacks"""
try:
if self.status_bar:
self.status_bar.config(text=str(message)[:100])
self.root.update_idletasks()
except Exception:
print(f"Status: {message}") # Console fallback - Safe Function Wrapper:
pythondef safe_wrapper(self, func, *args, **kwargs):
"""Wraps functions for safe execution"""
try:
return func(*args, **kwargs)
except Exception as e:
error_msg = f"Error in {func.name}: {str(e)}"
print(error_msg)
self.log_status(error_msg)
messagebox.showerror("Error", error_msg) - Robust UI Component Handling:
python# Before: Direct access (could crash)
After: Safe access with checks
- Progressive Feature Detection:
Module Availability: Only shows features if required modules are installed
Capability Detection: Detects what Chrome features are available
Graceful Fallbacks: Provides alternative functionality when advanced features aren't available
🔧 Debug-Safe Architecture:
- Initialization Safety:
All variables initialized with safe defaults
UI components created in proper order
Error handling during UI creation
Fallback to basic functionality if advanced features fail
- Operation Safety:
All file operations wrapped in try-catch blocks
Network operations with timeout handling
Process operations with proper exception handling
UI operations with null checks
- Recovery Mechanisms:
Automatic backup creation before destructive operations
Clear error reporting with suggested solutions
Partial success reporting (e.g., "3 of 5 profiles processed successfully")
Ability to continue after non-fatal errors
🚀 Debugging Benefits:
- Never Crashes:
All exceptions are caught and handled gracefully
UI remains responsive even during errors
Clear error messages instead of cryptic crashes
Continues working after individual operation failures
- Clear Feedback:
Real-time status updates during operations
Detailed error messages with context
Success/failure reporting for all operations
Progress indication for long-running tasks
- Safe Operations:
Automatic backups before any changes
Validation of files before operations
Safe process management
Rollback capabilities
- Debug Information:
Console output for debugging
Status bar updates
Error logging
Operation progress tracking
