#320: cooperation with Windows Vista's User Access Control ----------------------------+----------------------------------------------- Reporter: Toxaris | Owner: Type: enhancement | Status: new Priority: normal | Milestone: _|_ Component: Cabal library | Version: 1.4.0.1 Severity: normal | Resolution: Keywords: | Difficulty: normal Ghcversion: 6.8.2 | Platform: Windows ----------------------------+----------------------------------------------- Comment (by br1): FWIW, I asked Microsoft: Hi. I've been tracking some Haskell issues regarding permissions in Vista. Haskell includes a package manager for its libraries. It's not clear what the UAC story is for this. It's not right for the package manager to request admin privileges, because it forbids non-admin users to install a private version of the Haskell tools. Maybe you could take a look: http://hackage.haskell.org/trac/hackage/ticket/320#comment:5 This is the response: I'm not familiar with the tool or how it works. If you're creating a pure per-user application, then simply writing the files to a per-user location is sufficient. If you're looking for a per-machine install, you can use MSI Patches to upgrade without requiring admin rights, as described here: http://msdn.microsoft.com/en-us/library/aa370582(VS.85).aspx. I generally advise not trying to replicate the AccessCheck logic and elevate accordingly - it's too easy to get that wrong. Rather, just factor the application, and always elevate or never elevate (if it's per-user). -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/320#comment:7 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
