[GHC] #7646: resource busy (file is locked) with multi-threaded file ops
by GHC 04 Feb '13

#7646: resource busy (file is locked) with multi-threaded file ops ----------------------------------------+----------------------------------- Reporter: StefanWehr | Owner: Type: bug | Status: new Priority: normal | Component: Runtime System Version: 7.6.1 | Keywords: Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: Incorrect result at runtime | Blockedby: Blocking: | Related: ----------------------------------------+----------------------------------- The sample program attached creates 10 worker threads, each of which takes a different file name. Each worker thread then writes the file, reads the file, writes the file and so on. File operations use *strict IO*. When compiled without `-threaded` everything is ok, that is, the program goes on forever without any error messages. But with `-threaded`, the program quickly fails with `ERROR in worker 4: 4: openBinaryFile: resource busy (file is locked)`. Tested under Mac OSX 10.8.2 and Linux. Tested with both GHC 7.6.1 and 7.6.2. I could reproduce the bug without +RTS -N -RTS and with this RTS option. A colleague of mine reports that it needs +RTS -N2 -RTS to reproduce the bug. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/7646> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

Right now if there's a warning you have to fix it right away, but changing it into a gently nudge at the end might give us the same problem we have with testsuite failures - it's too easy to ignore them and push anyway. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/2548#comment:12> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

I meant LANG and LC_ALL, etc. > Also, do you have a "locale" program? > If so, what is the output when you run it? There's no locale program. Only a setlocale(3) function.. http://www.openbsd.org/cgi- bin/man.cgi?query=setlocale&apropos=0&sektion=0&manpath=OpenBSD+Current&arch=i386&format=html Usually, applications (for example tmux, mutt, etc.) that may need to output unicode characters, understand the locale by reading those enviromental variables I mentioned above. I thought it would work like that with haskell, but I was wrong. Let me know if you need anything else.
