#4012: Compilation results are not deterministic -------------------------------------+------------------------------------- Reporter: kili | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.10.1 Component: Compiler | Version: 6.12.2 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Difficult (2-5 Type of failure: Other | days) Test Case: | Blocked By: Blocking: | Related Tickets: Differential Revisions: | -------------------------------------+------------------------------------- Comment (by simonpj): Thanks for producing a patch. THAT is the best way to move the ticket forward! I've added a saying: The above patches look commendably small. But the resulting code contains absolutely no clue about the importance of the way those particular lines of code are written. Please, I beg, * write a Note [Deterministic builds] somewhere, * describe the issues in the note, * mention the ticket #4012 for more background * refer to the Note from the places in the code that are carefully written to support determinism See our [wiki:Commentary/CodingStyle Coding Style guidelines]. Thank you! Does that close the ticket? Or are there further determinism issues?

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
