Major improvements: - Atomic file writes using temp file + rename pattern - Structured logging with logging module (replaces print) - StateField class for HAProxy state field indices - Helper function get_backend_and_prefix() to reduce duplication - Consistent exception chaining with 'from e' - Proper fd/temp_path tracking to prevent resource leaks - Added IOError handling in server management functions Technical changes: - save_map_file, save_servers_config, haproxy_save_state now use atomic writes with tempfile.mkstemp() + os.rename() - Standardized on 'set server state ready' (was 'enable server') - All magic numbers for state parsing replaced with StateField class Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
