Questions with details

有这样一段读取 UDP 数据的代码：

type PocNetManager struct {
	gnet.BuiltinEventEngine
	buffer         []byte
}

func (t *PocNetManager) OnTraffic(c gnet.Conn) (action gnet.Action) {
	n, err := c.Read(t.buffer)
	if err != nil {
		log.Error("read poc pkg error", t.myUID, zap.Error(err))
		return
	}
}

c 是一个 udpConn，我想知道 OnTraffic 函数会不会被并发调用。如果会并发调用，我可能需要把 OnTraffic 修改成下面这样：

func (t *PocNetManager) OnTraffic(c gnet.Conn) (action gnet.Action) {
        buffer := make([]byte, 10240)
	n, err := c.Read(buffer)
	if err != nil {
		log.Error("read poc pkg error", t.myUID, zap.Error(err))
		return
	}
}

感谢阅读，期望与你讨论，谢谢！

OnTraffic will be invoked simultaneously on multi-cores machine with Multicore=true or NumEventLoop>0, so don't share the single buffer across all connections.
