Thu Aug 6 06:18:10 PDT 2009 Simon Marlow * Add a unuque identifier for installed packages (part 3 of 9) Ignore-this: 455a736ea5a3241aa6040f4c684ab0b3 This part adds the InstalledPackageIndex type to Distribution.Simple.PackageIndex. Now that packages have a unique identifier within a package database, it makes sense to use this as the key for looking up installed packages, so InstalledPackageIndex is a mapping from InstalledPackageId to InstalledPackageInfo. Distribution.Simple.PackageIndex still supports other kinds of package mappings: PackageIndex is a mapping from PackageName. All the functions in the section "Special Queries" now work on InstalledPackageIndex rather than PackageFixedDeps pkg => PackageIndex pkg: topologicalOrder, reverseTopologicalOrder, dependencyInconsistencies, dependencyCycles, brokenPackages, dependencyClosure, reverseDependencyClosure dependencyGraph M ./Distribution/Simple/PackageIndex.hs -103 +146 View patch online: http://darcs.haskell.org/cabal/_darcs/patches/20090806131810-12142-7676550c4...
