Andreas Voellmy updated THRIFT-3116:
------------------------------------
Fix Version/s: 0.9.2
This appears to have been fixed in 0.9.2.
> Ambiguous exports in Haskell-generated code
> -------------------------------------------
>
> Key: THRIFT-3116
> URL: https://issues.apache.org/jira/browse/THRIFT-3116
> Project: Thrift
> Issue Type: Bug
> Components: Haskell - Compiler
> Affects Versions: 0.9.1
> Environment: Ubuntu 14.04
> Reporter: Andreas Voellmy
> Fix For: 0.9.2
>
>
> It looks like the Thrift-generated Haskell exports functions in a way that
> causes problems. For example, when I use thrift on the tutorial example, and
> then I start up ghci and do
> Prelude> :l Calculator_Client.hs
> [1 of 8] Compiling Shared_Types ( Shared_Types.hs, interpreted )
> [2 of 8] Compiling Tutorial_Types ( Tutorial_Types.hs, interpreted )
> [3 of 8] Compiling SharedService_Iface ( SharedService_Iface.hs, interpreted )
> [4 of 8] Compiling SharedService ( SharedService.hs, interpreted )
> [5 of 8] Compiling Calculator_Iface ( Calculator_Iface.hs, interpreted )
> [6 of 8] Compiling Calculator ( Calculator.hs, interpreted )
> [7 of 8] Compiling SharedService_Client ( SharedService_Client.hs,
> interpreted )
> [8 of 8] Compiling Calculator_Client ( Calculator_Client.hs, interpreted )
> Calculator_Client.hs:15:45:
> Ambiguous occurrence ‘zip’
> It could refer to either ‘Calculator_Client.zip’,
> defined at Calculator_Client.hs:112:1
> or ‘Data.ByteString.Lazy.zip’,
> imported from ‘Data.ByteString.Lazy’ at
> Calculator_Client.hs:24:1-27
> Failed, modules loaded: SharedService_Client, Shared_Types, Tutorial_Types,
> Calculator, SharedService, Calculator_Iface, SharedService_Iface.
> The problem is that zip (from the service definition) is also exported by
> Data.ByteString.Lazy. One solution to this is to import all modules using
> qualified imports.
