"""
Complete patch for cross-platform test compatibility.

This script automatically applies all necessary modifications to resolve
cross-platform compatibility issues in the zen-mcp-server project.

FIXED ISSUES:

1. HOME DIRECTORY DETECTION ON WINDOWS:
    - Linux tests (/home/ubuntu) failed on Windows
    - Unix patterns were not detected due to backslashes
    - Solution: Added Windows patterns + dual-path check

2. UNIX PATH VALIDATION ON WINDOWS:
    - Unix paths (/etc/passwd) were rejected as relative paths
    - Solution: Accept Unix paths as absolute on Windows

3. CROSS-PLATFORM TESTS:
    - Assertions used OS-specific separators
    - The safe_files test used a non-existent file on Windows
    - Solution: Use Path.parts + temporary files on Windows

4. SHELL SCRIPTS WINDOWS COMPATIBILITY:
    - Shell scripts didn't detect Windows virtual environment paths
    - Solution: Added detection for .zen_venv/Scripts/ paths

5. COMMUNICATION SIMULATOR LOGGER BUG:
    - AttributeError: logger used before initialization
    - Solution: Initialize logger before calling _get_python_path()

6. PYTHON PATH DETECTION ON WINDOWS:
    - Simulator couldn't find Windows Python executable
    - Solution: Added Windows-specific path detection

MODIFIED FILES:
- utils/file_utils.py : Home patterns + Unix path validation
- tests/test_file_protection.py : Cross-platform assertions
- tests/test_utils.py : Safe_files test with temporary file
- run_integration_tests.sh : Windows venv detection
- code_quality_checks.sh : Windows venv and tools detection
- communication_simulator_test.py : Logger initialization order + Windows paths

Usage:
     python patch_complet_crossplatform.py [--dry-run] [--backup] [--validate-only]

Options:
     --dry-run       : Show modifications without applying them
     --backup        : Create a backup before modification
     --validate-only : Only check if patches are applied
