phg 1c8396f020 Add comprehensive tests for filtering and import/export functionality 
- Created `test_filters.py` to test the EntryFilter and FilterOptions classes, covering default values, custom values, filtering by status, DNS type, resolution status, and search functionality.
- Implemented tests for combined filters and edge cases in filtering.
- Added `test_import_export.py` to test the ImportExportService class, including exporting to hosts, JSON, and CSV formats, as well as importing from these formats.
- Included tests for handling invalid formats, missing required columns, and warnings during import.
- Updated `uv.lock` to include `pytest-asyncio` as a dependency for asynchronous testing.

Active Context

Current Status: Phase 4 Completed Successfully! 🎉

Last Updated: 2025-01-17 22:26 CET

Recent Achievement

Successfully completed Phase 4: Import/Export System implementation! All 279 tests are now passing, representing a major milestone in the hosts TUI application development.

Phase 4 Implementation Summary

  • ✅ Complete Import/Export Service (src/hosts/core/import_export.py)

    • Multi-format support: HOSTS, JSON, CSV
    • Comprehensive validation and error handling
    • DNS entry support with proper validation workarounds
    • Export/import roundtrip data integrity verification
    • File format auto-detection and path validation

  • ✅ Comprehensive Test Coverage (tests/test_import_export.py)

    • 24 comprehensive tests covering all functionality
    • Export/import roundtrips for all formats
    • Error handling for malformed files
    • DNS entry creation with validation workarounds
    • All tests passing with robust error scenarios covered

  • ✅ DNS Entry Validation Fix

    • Resolved DNS entry creation issues in import methods
    • Implemented temporary IP workaround for DNS-only entries
    • Fixed class name issues (HostsParser vs HostsFileParser)
    • Fixed export method to use parser serialization properly

Current System Status

  • Total Tests: 279 passed, 5 warnings (non-critical async mock warnings)
  • Test Coverage: Complete across all core modules
  • Code Quality: All ruff checks passing
  • Architecture: Clean, modular, well-documented

Completed Phases

  1. ✅ Phase 1: DNS Resolution Foundation - DNS service, fields, and comprehensive testing
  2. ✅ Phase 2: DNS Integration - TUI integration, status widgets, and real-time updates
  3. ✅ Phase 3: Advanced Filtering - Status-based, DNS-type, and search filtering with presets
  4. ✅ Phase 4: Import/Export System - Multi-format import/export with validation and testing

Next Phase: Phase 5 - DNS Name Support

Focus on enhancing entry modals and editing functionality to fully support DNS names alongside IP addresses:

Phase 5 Priorities

  1. Update AddEntryModal (src/hosts/tui/add_entry_modal.py)

    • Add DNS name field option
    • Implement mutual exclusion logic (IP vs DNS name)
    • Add field deactivation when DNS name is present

  2. Enhance EditHandler (src/hosts/tui/edit_handler.py)

    • Support DNS name editing
    • IP field deactivation logic
    • Enhanced validation for DNS entries

  3. Parser DNS Metadata (src/hosts/core/parser.py)

    • Handle DNS name metadata in hosts file comments
    • Preserve DNS information during file operations

  4. Validation Improvements

    • Enhanced mutual exclusion validation
    • DNS name format validation
    • Error handling for invalid combinations

Technical Architecture Status

  • DNS Resolution Service: Fully operational with background/manual refresh
  • Advanced Filtering: Complete with preset management
  • Import/Export: Multi-format support with comprehensive validation
  • TUI Integration: Professional interface with modal dialogs
  • Data Models: Enhanced with DNS fields and validation
  • Test Coverage: Comprehensive across all modules

Key Technical Insights

  • DNS entry creation requires temporary IP workaround due to validation constraints
  • Parser class naming conventions are critical for import functionality
  • Export/import roundtrip validation ensures data integrity
  • Background DNS resolution integrates seamlessly with TUI updates
  • Filter system handles complex DNS entry scenarios effectively

Development Patterns Established

  • Test-Driven Development with comprehensive coverage
  • Modular architecture with clear separation of concerns
  • Consistent error handling and validation patterns
  • Professional TUI design with modal dialogs
  • Clean async integration for DNS operations
