Yuxuan Wang updated THRIFT-5527:
--------------------------------
Description:
This is an example snippet generated by the current version of compiler:
{code:go}
result := ResultType{}
var retval *ResponseType
if retval, err2 = p.handler.Handler(ctx, args.Request); err2 != nil {
tickerCancel()
switch v := err2.(type) {
case *ThriftIDLDefinedExceptionType:
result.Err = v
default:
if err2 == thrift.ErrAbandonRequest {
return false, thrift.WrapTException(err2)
}
x := thrift.NewTApplicationException(thrift.INTERNAL_ERROR,
"Internal error processing authenticateCookie: "+err2.Error())
oprot.WriteMessageBegin(ctx, "handler", thrift.EXCEPTION, seqId)
x.Write(ctx, oprot)
oprot.WriteMessageEnd(ctx)
oprot.Flush(ctx)
return true, thrift.WrapTException(err2)
}
} else {
result.Success = retval
}
tickerCancel()
if err3 := oprot.WriteMessageBegin(ctx, "handler", thrift.REPLY, seqId); err3
!= nil {
err = thrift.WrapTException(err3)
}
if err4 := result.Write(ctx, oprot); err == nil && err4 != nil {
err = thrift.WrapTException(err4)
}
if err5 := oprot.WriteMessageEnd(ctx); err == nil && err5 != nil {
err = thrift.WrapTException(err5)
}
if err6 := oprot.Flush(ctx); err == nil && err6 != nil {
err = thrift.WrapTException(err6)
}
if err != nil {
return
}
return true, err
{code}
so, when a handler returns ThriftIDLDefinedExceptionType exception, the Process
function would only return an error if it fails to write the exception to the
wire, and nil-error if the writing was successful. This will cause the
processer middlewares unable to access any exceptions defined in thrift IDLs.
