#371: cabal-install can break installed packages by rebuilding dependents ---------------------------------+------------------------------------------ Reporter: duncan | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: | ---------------------------------+------------------------------------------ Install plans sometime involve rebuilding a package. This is not a safe operation however. Rebuilding a package can and does change its ABI. The ideal solution is to use a persistent package store like nix. That would mean we do not replace any installed package, just add new instances. In the mean time however one solution would be to extend an install plan the re-installs a package such that it rebuilds all reverse dependencies too. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/371 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
