Enhance File Error Handling with Comprehensive Permission and Access Error Management

Description

Task

Implement robust error handling for file access and permission issues

Acceptance Criteria

• Robust error handling for file access errors
• Secure error responses without system details
• Comprehensive logging of access issues
• Consistent error handling across file operations

Summary of Work

This pull request implements robust error handling for file access and permission issues, improving the security and reliability of file serving operations.

Changes Made

• Extended FileAccessError to provide more detailed error categorization
• Improved fileErrorHandler middleware to handle different types of file access errors
• Enhanced checkFileAccess function with more granular error detection
• Added specific error handling for common file system access scenarios

Implementation Details

1. Error Categorization:

   • Created more specific error types within FileAccessError
   • Added detailed error logging for different access scenarios
   • Ensured no sensitive system information is exposed in error responses

2. Error Handling Improvements:

   • Implemented detailed error mapping for file system errors
   • Added comprehensive error detection in checkFileAccess
   • Ensured consistent error response format

3. Security Considerations:

   • Prevented information disclosure in error messages
   • Added logging for security-related access attempts
   • Maintained strict error handling principles

Testing Approach

• Validated error handling for various file access scenarios
• Tested different permission and access error conditions
• Ensured consistent and secure error responses
• Verified no sensitive information leakage

Important Notes

• Error messages are generalized to prevent information disclosure
• Logging captures detailed error information for internal review
• Future improvements may include more granular error tracking

Changes Made

• Extended FileAccessError class with more detailed error categorization
• Improved fileErrorHandler middleware to handle different file access scenarios
• Enhanced checkFileAccess function with more comprehensive error detection
• Added specific error logging for file access attempts
• Ensured secure and consistent error response format

Tests

• Validate error handling for different file access scenarios
• Test permission denied errors
• Verify secure error response format
• Ensure no sensitive information is leaked in error messages
