2008-10-11 Hackage status with GHC 6.10

[Don Stewart]

Daily update of the state of Hackage wrt. GHC 6.10 release candidates.

Lots of packages were updated today, Cabal 1.6 and cabal-install 0.6
were also put out. Things are in a good shape.

Note that you'll need a "soft dep" in your cabal index file,

    base < 4
    parsec < 3
    HaXml == 1.13.*
    QuickCheck < 2

for best results.

Using GHC 6.10 RC, Cabal 1.6 and cabal-install 1.16, of 684 libraries
and apps tried in total,

      1 UnpackFailed
      2 DownloadFailed
      2 InstallFailed
     16 ConfigureFailed
     74 DependencyFailed
    134 BuildFailed
    455 InstallOk

Compared to GHC 6.8.x's results, there are now *48* packages that
produce different results, or *6%* (down 2% from yesterday).

The most common issues are,

    * Changes to Arrow class definition
    * Changes to types of Map and Set functions
    * Cabal changes
    * Changes to ghc-api
    * Changes to when 'forall' is parsed (add Rank2Types)
    * GHC.Prim was moved,
    * Changes to -fvia-C and headers
    * GADT changes,
    * pragma warnings tightened
    * Integer constructors have moved
    * New warnings and used -Werror

How to address these, as library maintainers, is addressed here,
