ghc-pkg check problem in 6.10.2
by Simon Marlow 20 Apr '09

20 Apr '09

I just noticed that the new 'ghc-pkg check' feature exposes a silly mistake in the definition of the rts package that we ship with GHC 6.10.2: $ ghc-pkg check There are problems in package rts-1.0: include-dirs: PAPI_INCLUDE_DIR doesn't exist or isn't a directory ... To fix it, issue this command: $ ghc-pkg describe rts | sed 's/PAPI_INCLUDE_DIR//' | ghc-pkg update - and now "ghc-pkg check" should give no errors: $ ghc-pkg check $ (Except on Windows, where there also seems to be a problem with the Haddock package. Haddock itself is ok, but the Haddock library has some problems with its registration.) Cheers, Simon

That helped. $ aptitude remove ghc did not remove or install any packages, but now ghc --version says 6.10.2 on the other hand, ghc 6.8.2 is still on the system dpkg -l says ghc6 6.8.2dfsg1-1 GHC - the Glasgow Haskell Compilation system ghc6-doc 6.8.2dfsg1-1 Documentation for the Glasgow Haskell Compilation system ghc6-libsrc 6.6-3 Library Sources of GHC, the Glasgow Haskell Compilation system ghc6-prof 6.8.2dfsg1-1 Profiling libraries for the Glasgow Haskell Compilation system $ ls -l /usr/bin/ghc* /usr/bin/ghc -> /etc/alternatives/ghc /usr/bin/ghc6 -> ../lib/ghc-6.8.2/bin/ghc /usr/bin/ghc-6.8.2 -> ../lib/ghc-6.8.2/bin/ghc-6.8.2 /usr/bin/ghci -> /etc/alternatives/ghci /usr/bin/ghci6 -> ../lib/ghc-6.8.2/bin/ghci /usr/bin/ghci-6.8.2 -> ../lib/ghc-6.8.2/bin/ghci-6.8.2 /usr/bin/ghc-pkg -> /etc/alternatives/ghc-pkg /usr/bin/ghc-pkg6 -> ../lib/ghc-6.8.2/bin/ghc-pkg /usr/bin/ghc-pkg-6.8.2 -> ../lib/ghc-6.8.2/bin/ghc-pkg-6.8.2 /usr/bin/ghcprof -> /etc/alternatives/ghcprof /usr/bin/ghcprof6 -> ../lib/ghc-6.8.2/bin/ghcprof $ ls -l /etc/alternatives/ghc* /usr/bin/ghc -> /etc/alternatives/ghc /usr/bin/ghc6 -> ../lib/ghc-6.8.2/bin/ghc /usr/bin/ghc-6.8.2 -> ../lib/ghc-6.8.2/bin/ghc-6.8.2 /usr/bin/ghci -> /etc/alternatives/ghci /usr/bin/ghci6 -> ../lib/ghc-6.8.2/bin/ghci /usr/bin/ghci-6.8.2 -> ../lib/ghc-6.8.2/bin/ghci-6.8.2 /usr/bin/ghc-pkg -> /etc/alternatives/ghc-pkg /usr/bin/ghc-pkg6 -> ../lib/ghc-6.8.2/bin/ghc-pkg /usr/bin/ghc-pkg-6.8.2 -> ../lib/ghc-6.8.2/bin/ghc-pkg-6.8.2 /usr/bin/ghcprof -> /etc/alternatives/ghcprof /usr/bin/ghcprof6 -> ../lib/ghc-6.8.2/bin/ghcprof $ ls -l /usr/local/bin/ghc* /usr/local/bin/ghc -> ghc-6.10.2 /usr/local/bin/ghc-6.10.2 /usr/local/bin/ghci -> ghci-6.10.2 /usr/local/bin/ghci-6.10.2 /usr/local/bin/ghc-pkg -> ghc-pkg-6.10.2 /usr/local/bin/ghc-pkg-6.10.2 so /usr/local/bin shadows the /usr/bin directory? I am not sure if I'm going to run into trouble with this installation, so I decided to completely uninstall the old ghc6. It removed some other packages, too: g++-4.1{u} ghc6 ghc6-prof{a} haskell-utils{u} libgmp3-dev{u} libgmpxx4ldbl{u} libncurses5-dev{u} libreadline5-dev{u} libstdc++6-4.1-dev{u} After that, there was no ghc anymore except the 6.10.2 - as desired. But a hello-world-compilation failed because of missing lgmp. So I installed libgmp3-dev and libgmpxx4ldbl Now it seems to work again, but I expect to run in trouble again. I'll keep you up-to-date.

bug: unstable myThreadId in GHC 6.6.1
by Bulat Ziganshin 16 Apr '09

16 Apr '09

Hello glasgow-haskell-users, i've looked for this bug in Trac but don't found anything. so: startGUI action = runInBoundThread $ do unsafeInitGUIForThreadedRTS myThreadId >>= writeIORef guiThread action >>= widgetShowAll mainGUI guiThread = unsafePerformIO$ newIORef$ error "undefined GUI::guiThread" Later in the same thread i ask for myThreadId and get different value. interesting that value returned in startGUI is 23 while later values are about 7000. probably this reflects total amount of threads created so far so that's the problem. Win API call returns constant thread number (that looks natural since the thread is bound). so either: 1) it's feature - please mention this in docs 2) it was fixed since 6.6.1 3) we need full-scale bugreport using 6.10.2 -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com

GHC on AIX

Hi, I'm new to GHC (and Haskell). I have tried to install the newest available binary distribution of GHC for AIX which is GHC version 6.8.2. Unfortunately, it didn't work properly. Following the trivial installation steps as described in INSTALL file I executed the following commands: 1) ./configure --prefix=/home/nik/local 2) gmake install But I got the following error message: ------------------------------ -------------------------------------------------------------------------------------------------------- ....

GHC threading bug in QSem
by Neil Mitchell 08 Apr '09

08 Apr '09

Hi I believe the following program should always print 100: import Data.IORef import Control.Concurrent main = do sem <- newQSem (-99) r <- newIORef 0 let incRef = atomicModifyIORef r (\a -> (a+1,a)) sequence_ $ replicate 100 $ forkIO $ incRef >> signalQSem sem waitQSem sem v <- readIORef r print v Unfortunately, it doesn't seem to. Running on a 2 processor machine, with +RTS -N3 I usually get 100, but have got answers such as 49, 82, 95. With +RTS -N2 it doesn't seem to fail, but it does with -N4. This is using GHC 6.10.2 on Windows. Using GHC 6.8.3, I get answers /= 100 roughly every other time. >From reading the implementation of QSem, it doesn't seem that negative availability was considered. I think it would be need to be changed as: -- Invariant: avail >= 1 ==> null blocked waitQSem :: QSem -> IO () waitQSem (QSem sem) = do (avail,blocked) <- takeMVar sem -- gain ex. access if avail > 0 then putMVar sem (avail-1,[]) else do block <- newEmptyMVar putMVar sem (avail, blocked++[block]) -- changed line takeMVar block signalQSem :: QSem -> IO () signalQSem (QSem sem) = do (avail,blocked) <- takeMVar sem -- changed below if null blocked || avail < 0 then putMVar sem (avail+1,blocked) else putMVar sem (avail, tail blocked) putMVar (head blocked) () Writing parallel code is hard, so I could have easily got this wrong. I haven't looked at QSemN, which may need similar fixes (or may already deal with this) Thanks Neil
