Aki Sukegawa resolved THRIFT-3837.
----------------------------------
Resolution: Duplicate
Assignee: Aki Sukegawa
[~winterland], this is fixed in THRIFT-3570 but by the other way around:
requiring these versions you mentioned.
> Thift 0.9.3 can't be build with QuickCheck 2.8.2 and unordered-containers
> 0.2.6
> -------------------------------------------------------------------------------
>
> Key: THRIFT-3837
> URL: https://issues.apache.org/jira/browse/THRIFT-3837
> Project: Thrift
> Issue Type: Bug
> Components: Haskell - Library
> Affects Versions: 0.9.3
> Reporter: winterland
> Assignee: Aki Sukegawa
> Labels: build
> Fix For: 0.10.0
>
>
> QuickCheck 2.8.2 provide Arbitrary instance for Map and Set from containers
> already, this change result in failure of building thrift with:
> ```
> src/Thrift/Arbitraries.hs:29:10:
> Duplicate instance declarations:
> instance (Ord k, Arbitrary k, Arbitrary v) => Arbitrary (Map k v)
> -- Defined at src/Thrift/Arbitraries.hs:29:10
> instance [safe] (Ord k, Arbitrary k, Arbitrary v) =>
> Arbitrary (Map k v)
> -- Defined in ‘Test.QuickCheck.Arbitrary’
> src/Thrift/Arbitraries.hs:32:10:
> Duplicate instance declarations:
> instance (Ord k, Arbitrary k) => Arbitrary (Set.Set k)
> -- Defined at src/Thrift/Arbitraries.hs:32:10
> instance [safe] (Ord a, Arbitrary a) => Arbitrary (Set.Set a)
> -- Defined in ‘Test.QuickCheck.Arbitrary’
> ```
> Same thing happened for unordered-containers package where Hashable instance
> are defined from 0.2.6 version.
> A version constraint <2.8.2 on QuickCheck and <0.2.6 on unordered-containers
> should be added to thrift's cabal, this can be done using hackage's
> revision(editing cabal file without upload a new tarball), maintainer please
> do this!
