From 81cbe6ed7fed5002aaa5958c84dd9301fa506fa1 Mon Sep 17 00:00:00 2001 From: AstroAir Date: Sat, 5 Jul 2025 23:26:26 +0800 Subject: [PATCH 01/25] Implement persistent and scoped environment variable management - Added `EnvPersistent` class for managing persistent environment variables across different levels (process, user, system) with platform-specific implementations for Windows and Unix-like systems. - Introduced `EnvScoped` class for temporary environment variable management, ensuring original values are restored upon destruction. - Developed utility functions in `EnvUtils` for expanding environment variables, comparing and merging environment variable sets. - Implemented system information retrieval in `EnvSystem`, including home directory, temporary directory, configuration directory, data directory, system name, architecture, current user, and hostname. - Created a basic Python script for testing and a build script for optimized test components. - Added a command interface test to validate command execution, availability, and history management. --- .github/workflows/build.yml | 282 +++ .gitignore | 1 + .python-version | 1 + BUILD_SYSTEM.md | 288 +++

Subject: [PATCH 10/25] Add comprehensive tests for async connection components - Implemented tests for async socket hub, including connection management, message sending/receiving, and group management. - Added tests for async TCP client, covering connection states, data transfer, and error handling. - Created tests for async UDP client, focusing on sending/receiving data, multicast, and error scenarios. - Introduced SSL tests for both TCP and UDP clients to ensure secure connections. - Utilized mock servers to simulate network behavior for thorough testing. --- .gitattributes | 20 +-
