game服务发送Game_Kick消息无法断开与客户端的连接

[seangx]

似乎是这里的case <-sess.Die无法进去，不知道该怎么改...

for {
		// solve dead link problem:
		// physical disconnection without any communcation between client and server
		// will cause the read to block FOREVER, so a timeout is a rescue.
		conn.SetReadDeadline(time.Now().Add(config.readDeadline))

		// read 2B header
		n, err := io.ReadFull(conn, header)
		if err != nil {
			log.Warningf("read header failed, ip:%v reason:%v size:%v", sess.IP, err, n)
			return
		}
		size := binary.BigEndian.Uint16(header)

		// alloc a byte slice of the size defined in the header for reading data
		payload := make([]byte, size)
		n, err = io.ReadFull(conn, payload)
		if err != nil {
			log.Warningf("read payload failed, ip:%v reason:%v size:%v", sess.IP, err, n)
			return
		}

		// deliver the data to the input queue of agent()
		select {
		case in <- payload: // payload queued
		case <-sess.Die:
			log.Warningf("connection closed by logic, flag:%v ip:%v", sess.Flag, sess.IP)
			return
		}
	}
