从命令行关闭机器人时,我需要多次点击 ^C,因为我的事件侦听器线程似乎没有正确关闭。我需要更改停用功能吗?

class Icinga2bot(BotPlugin):
    """
    Use errbot to talk to an Icinga2 monitoring server.
    """

    def report_events(self):
        '''Relay events from the Icinga2 API to a chat channel. Not interactive.
        The event queues are selected in icinga2bot.ini'''
        while not self.stop_thread.is_set():
            queue = i2events()
            room = self.query_room(self.bot_config.CHATROOM_PRESENCE[0])
            debug(room)
            for line in queue:
                self.send(room,line)
                debug(line)


    def activate(self):

        self.thread = threading.Thread(target = self.report_events)
        self.thread.start()
        super(Icinga2bot, self).activate()

    def deactivate(self):
        """

        self.stop_thread.set()

        self.thread.join()
        debug('thread.join() complete')
        super(Icinga2bot, self).deactivate()

控制台窗口显示插件在设置停止标志和等待线程完成之间陷入困境。
