Bug Description

Binary package hint: ghc6

Hi,

I am importing this RC bug from Debian so that you can consider
it for Intrepid.

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=491909

Package: ghc6
Version: 6.8.2-5
Severity: important

Just importing this bug from upstream:

    # http://hackage.haskell.org/trac/ghc/ticket/2038

    import System.Exit (exitWith, ExitCode(ExitSuccess))
    import System.IO (putStrLn)
    import System.Posix.Resource

    rlimit = ResourceLimit 3

    f = do
        putStrLn "whoooooo"
        f
    main = do
        setResourceLimit ResourceCPUTime (ResourceLimits rlimit rlimit)
        r <- getResourceLimit ResourceCPUTime
        let (ResourceLimit s) = softLimit r
        let (ResourceLimit h) = hardLimit r
        putStrLn $ show s
        putStrLn $ show h
        f
        exitWith ExitSuccess

   Returns:

     $ strace -etrace=setrlimit ./m
     setrlimit(RLIMIT_CPU, {rlim_cur=3, rlim_max=0}) = -1 EINVAL (Invalid
                                                                   argument)
     m: setResourceLimit: invalid argument (Invalid argument)

.. so that I can request that the patch be applied to ghc6 for Lenny. As
Eelis mentions on the haskell.org BR, this breaks geordi on x86-32.

It has been fixed on Debian by backporting the changes.

Thanks,

James

This debdiff applies to the current Ubuntu version and will merge it with the new Debian revision, which has the fix. As far as I can tell, this issue is resolved with the new package. I guess we must rebuild geordi too?

Hi,

yes, geordi will need a rebuild as well.

However I've been thinking about bug #263773, maybe it might make sense to only do one upload fixing both. I'll leave a comment on that bug.

Cheers,
    Stefan.

Well I think that given that the other fix is potentially (probably) rather dangerous, it makes sense to do them in separate uploads, for ease of reverting if nothing else. Also there's the fact that it's not at all clear if we even want to do anything for bug #263773 yet, whereas we can close this one out now and forget about it.
