From 7437eb4c0201038022dbc269cb0b93b817b7b624 Mon Sep 17 00:00:00 2001 From: Lukas Date: Wed, 22 Oct 2025 13:00:09 +0200 Subject: [PATCH] refactor: improve code quality - fix imports, type hints, and security issues ## Critical Fixes - Create error_handler module with custom exceptions and recovery strategies - Adds RetryableError, NonRetryableError, NetworkError, DownloadError - Implements with_error_recovery decorator for automatic retry logic - Provides RecoveryStrategies and FileCorruptionDetector classes - Fixes critical import error in enhanced_provider.py - Fix CORS security vulnerability in fastapi_app.py - Replace allow_origins=['*'] with environment-based config - Use settings.cors_origins for production configurability - Add security warnings in code comments ## Type Hints Improvements - Fix invalid type hint syntax in Provider.py - Change (str, [str]) to tuple[str, dict[str, Any]] - Rename GetLink() to get_link() (PEP8 compliance) - Add comprehensive docstrings for abstract method - Update streaming provider implementations - voe.py: Add full type hints, update method signature - doodstream.py: Add full type hints, update method signature - Fix parameter naming (embededLink -> embedded_link) - Both now return tuple with headers dict - Enhance base_provider.py documentation - Add comprehensive type hints to all abstract methods - Add detailed parameter documentation - Add return type documentation with examples ## Files Modified - Created: src/core/error_handler.py (error handling infrastructure) - Modified: 9 source files (type hints, naming, imports) - Added: QUALITY_IMPROVEMENTS.md (implementation details) - Added: TEST_VERIFICATION_REPORT.md (test status) - Updated: QualityTODO.md (progress tracking) ## Testing - All tests passing (unit, integration, API) - No regressions detected - All 10+ type checking violations resolved - Code follows PEP8 and PEP257 standards ## Quality Metrics - Import errors: 1 -> 0 - CORS security: High Risk -> Resolved - Type hint errors: 12+ -> 0 -
