#224: allow specifying package version constraints to configure ----------------------------+----------------------------------------------- Reporter: duncan | Owner: Type: enhancement | Status: closed Priority: normal | Milestone: Cabal-1.4 Component: Cabal library | Version: 1.2.3.0 Severity: normal | Resolution: fixed Keywords: | Difficulty: normal Ghcversion: 6.8.2 | Platform: ----------------------------+----------------------------------------------- Changes (by duncan): * status: new => closed * resolution: => fixed Comment: Fixed: {{{ Sun Apr 13 14:18:07 BST 2008 Thomas Schilling * Change dependency resolution algorithm. There were two reasons to do this. Firstly, this formulation makes it easier to add the --constraint command line flag that adds additional constraints on the packages that should be used. Secondly, with the orgininal algorithm it was possible to satisfy the constraint "foo < 1, foo > 2" if we had two versions of package "foo" which each satisfy one constraint. This patch fixes this by requiring the same package to satisfy both constraints (which of course is impossible in this case). Sun Apr 13 19:26:59 BST 2008 Thomas Schilling * Fix #224. We do not yet warn if the user specified a dependency that did not occur in the package (it is just silently ignored.) }}} -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/224#comment:3 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
