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, http://haskell.org/haskellwiki/Upgrading_packages Packages that have broken wrt. the new core library APIs are, ArrayRef-0.1.2 CLASE-2008.9.23.2 EdisonCore-1.2.1.2 HPDF-1.4 HaLeX-1.1 Hashell-0.15 Hipmunk-0.2 MemoTrie-0.0 NewBinary-0.1.1 PArrows-0.1 TypeCompose-0.5 WebBits-0.9.2 YamlReference-0.9.2 Yampa-0.9.2.2 arrows-0.4 bytestring-show-0.2 cabal-setup-1.2.1 chp-1.1.0 cmath-0.3 fixpoint-0.1 hasim-0.1 hask-home-2007.12.6 heap-0.4.0 hetris-0.2 hexpat-0.2 hinstaller-2008.2.16 hint-0.2.4.1 hslackbuilder-0.0.1 hxt-8.1.0 iException-0.0.1 libGenI-0.16.1 list-extras-0.2.2 logfloat-0.9.1 mage-1.1.0 numeric-prelude-0.0.4 plugins-1.3 quantum-arrow-0.0.4 regex-tdfa-0.94 streamproc-1.1 stringtable-atom-0.0.4 typalyze-0.1.1 unicode-prelude-0.1 xmonad-utils-0.1 yhccore-0.9 GHC bugs are suspected for, xmonad-contrib, stream-fusion, harpy, OpenAFP Tickets are open for these.
