#9058: System.IO.openTempFile does not scale -------------------------------------+------------------------------------ Reporter: slyfox | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by slyfox): Here is one simple solution. it basically changes prefix ++ getpid() ++ suffix for prefix ++ rand() ++ rand() ++ suffix Technically rand() might be thread-unsafe (but not on glibc, there random_r() is used silently) but i don't think it's a troblem at all. Otherwise we could use time-based timestamp, but picking precise time source (to use it more, than 1000 times a second) might be a problem. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9058#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
