#1487: unix package: test needed for getLoginName -------------------------------------+------------------------------------- Reporter: simonmar | Owner: Type: bug | Status: new Priority: lowest | Milestone: Component: | Version: libraries/unix | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: Linux | Difficulty: Easy (less than 1 Type of failure: Incorrect | hour) result at runtime | Blocked By: Test Case: | Related Tickets: #8293 Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by thomie): @ezyang: which terminal emulator are you using? Does it work with `xterm`? Maybe we should change the signature of `getLoginName` to: {{{ getLoginName :: IO (Maybe String) }}} , since the man page explicitly mentions that [http://linux.die.net/man/3/getlogin getlogin] can return NULL: {{{ getlogin() returns a pointer to a string containing the name of the user logged in on the controlling terminal of the process, or a NULL pointer if this information cannot be determined. }}} The same applies to `getGroupEntryForID`, ticket #8293. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/1487#comment:24 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
