gunli opened a new issue, #11954:
URL: https://github.com/apache/inlong/issues/11954
### What happened
In Golang SDK, when we receive a response, we discard the ring buffer of
gent before we handling the response, which will cause data race.
```go
func (c *client) OnTraffic(conn gnet.Conn) (action gnet.Action) {
// c.log.Debug("response received")
for {
total := conn.InboundBuffered()
if total < heartbeatRspLen {
break
}
buf, _ := conn.Peek(total)
// if it is a heartbeat response, skip it and read the next
package
if bytes.Equal(buf[:heartbeatRspLen], heartbeatRsp) {
_, err := conn.Discard(heartbeatRspLen)
if err != nil {
c.metrics.incError(errConnReadFailed.getStrCode())
c.log.Error("discard connection stream failed,
err", err)
// read failed, close the connection
return gnet.Close
}
c.log.Debug("heartbeat rsp receive")
continue
}
length, payloadOffset, payloadOffsetEnd, err :=
c.framer.ReadFrame(buf)
if errors.Is(err, framer.ErrIncompleteFrame) {
break
}
if err != nil {
c.metrics.incError(errConnReadFailed.getStrCode())
c.log.Error("invalid packet from stream connection,
close it, err:", err)
// read failed, close the connection
return gnet.Close
}
frame, _ := conn.Peek(length)
_, err = conn.Discard(length)
// discard will release the buffer and it can be written
again
if err != nil {
c.metrics.incError(errConnReadFailed.getStrCode())
c.log.Error("discard connection stream failed, err",
err)
// read failed, close the connection
return gnet.Close
}
// handle response
c.onResponse(frame[payloadOffset:payloadOffsetEnd])
// handle the response here, but the frame may be truncated
}
return gnet.None
}
```
