>             Project: Thrift
>          Issue Type: Bug
>          Components: Go - Library
>    Affects Versions: 0.10.0

> The current (as of 72ca60d) pattern for [TTransport factories|https://github.com/apache/thrift/blob/master/lib/go/thrift/transport_factory.go#L26] in Golang is 
> {code}
> type TTransportFactory interface {
> 	GetTransport(trans TTransport) TTransport
> }
> {code}
> This causes issues, because some {{TTransportFactory}} implementations can return and error. Consider the [THttpClientTransportFactory|https://github.com/apache/thrift/blob/master/lib/go/thrift/http_client.go#L52], which as of of 72ca60d, includes the following snippet:
>  
> {code}
> 	s, _ := NewTHttpClientWithOptions(p.url, p.options)
> 	return s
> {code}
> The call to {{NewTHttpClientWithOptions(...)}} call can throw errors. The resultant behavior is that {{nil}} is returned in place of a valid {{TTransport}}, with a {{nil}} error.
> The {{TTransportFactory}} interface (and associated use patterns) should be extended to include errors.
