> Key: THRIFT-3108
> URL: https://issues.apache.org/jira/browse/THRIFT-3108
> Project: Thrift
> Issue Type: Bug
> Components: Haskell - Compiler
> Environment: GHC 7.6.3
> GHC 7.8.4
> Reporter: Sean Parsons
> Priority: Blocker
>
> If we have a service definition that looks something like:
> {code:none}
> struct ServiceRequest {
> 1: optional bool shouldWork;
> }
> service MyService{
> void myService(1:ServiceRequest request = {});
> }
> {code}
> The code generation relating to the service call includes an invocation like
> this:
> {code:none}
> ... = default_ServiceRequest{}
> {code}
> Which is invalid as empty record updates are not allowed.
