#434: Let packages opt-in to the Package Versioning Policy ----------------------------+----------------------------------------------- Reporter: duncan | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Cabal-1.8 Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.3 Platform: | ----------------------------+----------------------------------------------- Package version numbers and version constraints on dependencies are proxies for API compatibility. It is hard for people to specify the dependencies correctly and we would like to improve their quality. We have the [http://haskell.org/haskellwiki/Package_versioning_policy Package versioning policy] which says how the package version number relates to API changes. What we want is a mechanism by which package authors can opt-in to the versioning policy. We should then get hackage to check that the package really is following the policy. Just as important we can use the fact that a package does follow the policy to give suggestions to package authors. For one thing we can discourage or ban upwardly open version ranges and provide a suggestion on what upper version bound to use. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/434 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
