patch applied (cabal-install): Switch DependencyResolver to return Progress and String errors
by Duncan Coutts 30 May '08

30 May '08

Thu May 29 13:48:49 PDT 2008 Duncan Coutts <duncan(a)haskell.org> * Switch DependencyResolver to return Progress and String errors rather than Either and structured error type [Dependency]. The reason we cannot use that as a structured error type any more is because missing dependencies is not the only failure reason. There are several reasons, several of which are pretty complex. For now we'll have to do with a human readable message. Perhaps we may be able to find a common structured type that the different dep resolvers can all agree on. I'm not hopeful however as error reporting seems to be closely tied to the dep resolution approach.

patch applied (cabal-install): First version of the top-down package dependency resolver
by Duncan Coutts 29 May '08

29 May '08

Wed May 28 14:58:04 PDT 2008 Duncan Coutts <duncan(a)haskell.org> * First version of the top-down package dependency resolver This is a new dependency resolver that produces valid install plans. It works in polynomial time however because the search space is exponential in size it is not guaranteed to find a solution even if one exists. It works by generating and then exploring the search space represented as a lazy tree. It uses constraints to prune choices and heuristics when guesses are necessary. Currently it can generate install plans for 99% of the packages on hackage. The remaining 6 packages should be doable with two extra tricks. It is not finished and is not yet usable in practice.

patch applied (cabal-branches/cabal-1.4): Change the PackageIndex invariant so the buckets are ordered

29 May '08

Thu May 29 02:53:46 PDT 2008 Duncan Coutts <duncan(a)haskell.org> * Change the PackageIndex invariant so the buckets are ordered Each bucket holds packages with the same name case-insensitively. Previously each buckets was internally unordered. Now they're ordered by the full package id which means first by package name case-sensitively and then by version.
