-------------------------------------
Added PR yesterday. Have a look :-)
> Go Struct writer and reader looses important error information
> --------------------------------------------------------------
>
> Key: THRIFT-2854
> URL: https://issues.apache.org/jira/browse/THRIFT-2854
> Project: Thrift
> Issue Type: Bug
> Components: Go - Compiler
> Affects Versions: 0.9.2
> Reporter: Chi Vinh Le
> Fix For: 0.9.3
>
>
> The GO Compiler generates code for a struct so that the following occurs:
> When an error occurs while reading or writing, a new error is created with
> additional text information using {code}fmt.Errorf{code}.
> By doing this the original error is completely lost. This is a real problem
> because errors of type TTransportException and TProtocolExceptions which
> contain additional information are lost. This will cause bad error handling,
> as the server implementation is dependent on those information.
> In my personal fork, I have a quick'n dirty fix for this, but I'm looking for
> a better option.
> Maybe instead of {code}fmt.Errorf{code} we could use this:
> {code}
> // Prepends additional information to an error without losing the Thrift
> interface
> func PrependError(err error, prepend string) error {
> if t, ok := err.(TTransportException); ok {
> return NewTTransportException(t.TypeId(), prepend+t.Error())
> }
> if t, ok := err.(TProtocolException); ok {
> return NewTProtocolExceptionWithType(t.TypeId(),
> errors.New(prepend+err.Error()))
> }
> if t, ok := err.(TApplicationException); ok {
> return NewTApplicationException(t.TypeId(), prepend+t.Error())
> }
> return errors.New(prepend + err.Error())
> }
> {code}
> I want to discuss this first here, because making a patch is quiet some work
> and I don't want major changes after I create a fix.
