Re: [Hackage] #485: preference on base version should only be applied for open constraints

#485: preference on base version should only be applied for open constraints ---------------------------------+------------------------------------------ Reporter: duncan | Owner: Type: enhancement | Status: new Priority: high | Milestone: cabal-install-0.6 Component: cabal-install tool | Version: 1.6.0.1 Severity: normal | Resolution: Keywords: | Difficulty: easy (<4 hours) Ghcversion: | Platform: ---------------------------------+------------------------------------------ Changes (by duncan): * priority: normal => high * difficulty: unknown => easy (<4 hours) Comment: {{{ Wed Jun 3 11:16:23 BST 2009 Duncan Coutts * Only apply preferences to base if its version is unbounded above Fixes ticket #485. This means that for constraints like: build-depends: base >= 3 && < 5 we will pick version 4. However we will continue to apply the version 3 preference for things like: build-depends: base >= 3 Where there is no upper bound on the version. Note that we now also ignore preferences for base given on the command line. We should implement #483 to split prefs from shims. }}} Needs testing and then back-porting to the cabal-install-0.6.x series. In particular it'll need a compat copy of the newVersionIntervals type that's in the Cabal lib now as of version 1.7.x. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/485#comment:3 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
