#16260: Use of plugins causes -XSafe to fail -------------------------------------+------------------------------------- Reporter: watashi | Owner: watashi Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 8.7 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by mpickering): My reasoning is that if a consumer decides that they don't care about Safe Haskell then they can use `-fno-safe-haskell` and skip the checks. However, if a user does care about safe haskell then they would care if one of their dependencies was modified with a plugin, this kind of situation is easy to achieve when using nix for example. If it is up to the plugin authors to be prudent, I imagine that none of them will be. Perhaps if we just modify the `Sf_Ignore` constructor to be `Sf_Ignore SafeHaskellMode` to record the mode it is ignoring then that would solve your problem? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16260#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
