Implementation Reference
- src/uart_mcp/tools/terminal.py:39-49 (handler)The top-level handler function for the 'close_session' tool. It retrieves the terminal manager and calls its close_session method.def close_session(session_id: str) -> dict[str, Any]: """关闭指定终端会话 Args: session_id: 会话ID（串口路径） Returns: 操作结果 """ manager = get_terminal_manager() return manager.close_session(session_id)
- Core implementation in TerminalManager that safely closes a session: removes it from the sessions dict, stops the read thread, and returns success.def close_session(self, session_id: str) -> dict[str, Any]: """关闭终端会话 Args: session_id: 会话ID（串口路径） Returns: 操作结果 Raises: SessionNotFoundError: 会话不存在 """ with self._lock: if session_id not in self._sessions: raise SessionNotFoundError(session_id) session = self._sessions.pop(session_id) session.stop() logger.info("关闭终端会话：%s", session_id) return {"success": True, "session_id": session_id}
