示例1: getStreamError
func getStreamError(stream sqltypes.ResultStream, err error) error {
if err != nil {
return err
}
for {
_, err := stream.Recv()
switch err {
case nil:
// keep going
case io.EOF:
return nil
default:
return err
}
}
}示例2: processOneStreamingResult
func (stc *ScatterConn) processOneStreamingResult(mu *sync.Mutex, stream sqltypes.ResultStream, err error, replyErr *error, fieldSent *bool, sendReply func(reply *sqltypes.Result) error) error {
if err != nil {
return err
}
for {
qr, err := stream.Recv()
if err != nil {
if err == io.EOF {
return nil
}
return err
}
mu.Lock()
if *replyErr != nil {
mu.Unlock()
// we had an error sending results, drain input
for {
if _, err := stream.Recv(); err != nil {
break
}
}
return nil
}
// only send field info once for scattered streaming
if len(qr.Fields) > 0 && len(qr.Rows) == 0 {
if *fieldSent {
mu.Unlock()
continue
}
*fieldSent = true
}
*replyErr = sendReply(qr)
mu.Unlock()
}
