#665: Confusion situation when linking ./dist/setup/setup is interrupted ---------------------------------+------------------------------------------ Reporter: duncan | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.6.0.3 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ If one accidentally interrupts cabal when it's linking `./dist/setup/setup` then you can end up with the file existing it not being executable. This leads to a confusing situation for the user. Running `cabal install` or `cabal configure` will fail silently. Running with -v indicates that something returns exit code 127. This corresponds to a permission error when trying to execute `./dist/setup/setup` Two improvements could be made: * Report the failure to execute `./dist/setup/setup` * If ghc is interrupted when creating `./dist/setup/setup`, cabal should delete the file, if it exists. That way, cabal will recompile on the next invocation. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/665 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
