- 在 BaseFlowProxyPlugin._setup_logging 中设置 propagate=True - 使插件日志同时输出到控制台（彩色）和文件（通过 root logger） 影响： - 插件日志现在会正确写入日志文件 - 控制台输出保持彩色 - 所有测试通过 (200/200) 已知问题： - 日志文件中包含 ANSI 颜色代码（将在后续提交中修复） ---

logger 的 file handler - 子进程继承了主进程，但 Python logging handlers 在多进程环境下可能失效 - 插件在子进程中初始化，之前的 propagate=True 方案依赖 root logger - 但子进程的 root logger file handler 可能已经失效 解决方案： - 不再依赖 propagate，改为直接复制 root logger 的 file handler - 在插件的 _setup_logging() 中： 1. 使用 setup_colored_logger 设置控制台输出（propagate=False） 2. 遍历 root logger 的 handlers 3. 将 file handlers 直接添加到插件 logger - 这样即使在子进程中，插件 logger 也有自己的 file handler 效果： - 插件日志在多进程环境下正确写入文件 - 控制台保持彩色输出 - 避免日志重复（propagate=False） - 所有测试通过 (200/200) --- flow_proxy_plugin/plugins/base_plugin.py | 15 +++++++++++++-- 1 file changed, 13 insertions(+), 2
