[Hackage] #709: cabal doesn't handle error conditions from getAppUserDataDirectory
#709: cabal doesn't handle error conditions from getAppUserDataDirectory ----------------------------+----------------------------------------------- Reporter: creswick | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.8.0.2 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: 6.12.1 Platform: Windows | ----------------------------+----------------------------------------------- Distribution.Simple.InstallDirs.defaultInstallDirs fails if getAppUserDataDirectory fails, and it does so with a very uninformative error: {{{ # On Cabal 1.8.0.2: cabal.exe: illegal operation }}} This is a slight regression from the HP 2009 version: {{{ # On Cabal 1.6.0.3: cabal.exe: System.Directory.getAppUserDataDirectory: unsupported operation (unsupported operation) }}} This happens on Windows Vista, in cygwin, when the user doesn't have a windows user directory (eg: c:\users\username ). -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/709 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

It means we cannot read the config file. The error message issue could do with some work. We should make sure the topHandler is not throwing useful information away. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/709#comment:2 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
