#9044: createDirectoryIfMissing does not fail on unwritable parent dir -------------------------------------+------------------------------------- Reporter: duncan | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: | Version: 7.8.2 libraries/directory | Operating System: MacOS X Keywords: | Type of failure: Incorrect result Architecture: Unknown/Multiple | at runtime Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | -------------------------------------+------------------------------------- On OSX, using `createDirectoryIfMissing` to create a new directory inside a directory for which we do not have write permissions does not throw any exception. Of course it should throw an exception, as it does under Linux. {{{ $ mkdir unwritable $ chmod ugo-w unwritable $ ghci

System.Directory.createDirectoryIfMissing True "unwritable/tst"

}}} On OSX (10.9.2) this does not fail. Under Linux (albeit with 7.6.3) this does throw an exception as expected: {{{ *** Exception: unwritable/tst: createDirectory: permission denied (Permission denied) }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9044 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
