Sun Oct 5 20:02:59 PDT 2008 Duncan Coutts <duncan(a)haskell.org> * Read preferred versions from the package index From a file named 'preferred-versions' in the 00-index.tar.gz If there are several they are combined. Contents is like: base < 4 one suggested version constraint per line.

patch applied (cabal-install): When finalising paired packages, cope with there being multiple choices
by Duncan Coutts 06 Oct '08

06 Oct '08

Sat Oct 4 22:38:21 PDT 2008 Duncan Coutts <duncan(a)haskell.org> * When finalising paired packages, cope with there being multiple choices For ordinary packages we selected a single version which means we added an equality constraint. As a consequence we used to assume there was only one version left when finalising. For paired packages there may be two versions left if the package did not directly constrain the choice to just one. If there is more than one version remaining then we have to pick between them. At the moment we still pick the highest version, but later we can take a global preference or polciy into account.

patch applied (cabal-install): Handle constraints on paired packages
by Duncan Coutts 06 Oct '08

06 Oct '08

Sat Oct 4 22:19:19 PDT 2008 Duncan Coutts <duncan(a)haskell.org> * Handle constraints on paired packages The trick is that when applying constraints to paired packages, the constraint has to exclude both packages at once. We exclude the pair together or not at all. If it would only exclude one then we discard the constraint.

patch applied (cabal-install): Add the notion of paired packages to the Constraints ADT
by Duncan Coutts 06 Oct '08

06 Oct '08

Sat Oct 4 18:31:41 PDT 2008 Duncan Coutts <duncan(a)haskell.org> * Add the notion of paired packages to the Constraints ADT Packages like base-3 and base-4 are paired. This means they are supposed to be treated equivalently in some contexts. Paired packages are installed packages with the same name where one version depends on the other.

patch applied (cabal-install): Have Constraints.constrain report the excluded packages
by Duncan Coutts 06 Oct '08

06 Oct '08

Sat Oct 4 16:50:06 PDT 2008 Duncan Coutts <duncan(a)haskell.org> * Have Constraints.constrain report the excluded packages Each time we apply a constraint we can end up excluding some extra package. Report that list of packages because it is quite interesting information to get insight into what the resolver is actually doing.
