----------------------------------
Assignee: Jens Geyer
> Generated golang server codes for "oneway" interface is incorrect
> -----------------------------------------------------------------
>
> Key: THRIFT-2458
> URL: https://issues.apache.org/jira/browse/THRIFT-2458
> Project: Thrift
> Issue Type: Bug
> Components: Go - Compiler
> Affects Versions: 0.9.1
> Reporter: Brian Jiang
> Assignee: Jens Geyer
> Priority: Critical
>
> oneway interface call is only a notification. server shall not send any
> response. But currently the golang server codes generated by complier will
> send a response. That will make the subsequent RPC call failed due to this
> unexpected result in the receiving networking stream. (The client is not
> expecting a reply for oneway call)
> Here is an example of generated codes for a oneway call (oneway void hi()),
> it shall not write a result back.
> func (p *testProcessorHi) Process(seqId int32, iprot, oprot thrift.TProtocol)
> (success bool, err thrift.TException) {
> args := NewHiArgs()
> if err = args.Read(iprot); err != nil {
> iprot.ReadMessageEnd()
> x := thrift.NewTApplicationException(thrift.PROTOCOL_ERROR,
> err.Error())
> oprot.WriteMessageBegin("hi", thrift.EXCEPTION, seqId)
> x.Write(oprot)
> oprot.WriteMessageEnd()
> oprot.Flush()
> return
> }
> iprot.ReadMessageEnd()
> result := NewHiResult()
> if err = p.handler.Hi(); err != nil {
> x := thrift.NewTApplicationException(thrift.INTERNAL_ERROR,
> "Internal error processing hi: "+err.Error())
> oprot.WriteMessageBegin("hi", thrift.EXCEPTION, seqId)
> x.Write(oprot)
> oprot.WriteMessageEnd()
> oprot.Flush()
> return
> }
> if err2 := oprot.WriteMessageBegin("hi", thrift.REPLY, seqId); err2 !=
> nil {
> err = err2
> }
> if err2 := result.Write(oprot); err == nil && err2 != nil {
> err = err2
> }
> if err2 := oprot.WriteMessageEnd(); err == nil && err2 != nil {
> err = err2
> }
> if err2 := oprot.Flush(); err == nil && err2 != nil {
> err = err2
> }
> if err != nil {
> return
> }
> return true, err
> }
