----------------------------------------
GitHub user dcelasun opened a pull request:
https://github.com/apache/thrift/pull/1285
THRIFT-4215/4216 Make transport factories return errors
This commit changes the signature of `TTransportFactory.GetTransport` from
```go
GetTransport(trans TTransport) TTransport
```
to
```go
GetTransport(trans TTransport) (TTransport, error)
```
so the factory can pass any underlying error to the caller (previously such
errors were ignored).
This is a backwards incompatible change for anyone implementing custom
transports, but it shouldn't effect anyone using the ones in this library.
Fixes [THRIFT-4215](https://issues.apache.org/jira/browse/THRIFT-4215).
Fixes [THRIFT-4216](https://issues.apache.org/jira/browse/THRIFT-4216).

> Golang TTransportFactory Pattern Squelches Errors
> -------------------------------------------------
>
> Key: THRIFT-4215
> URL: https://issues.apache.org/jira/browse/THRIFT-4215
> Project: Thrift
> Issue Type: Bug
> Components: Go - Library
> Affects Versions: 0.10.0
> Reporter: James Mouradian
> Assignee: Can Celasun
>
> 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.
