ANNOUNCE: GHC vesrion 5.04.3 released
==
The (Interactive) Glasgow Haskell Compiler -- version 5.04.3
==
We are pleased to announce a new patchlevel release of the Glasgow
Haskell Compiler (GHC), version 5.04.3. This is a bugfix-only
release. For all the changes since 5.02.3, see the release notes:
http://www.haskell.org/ghc/docs/latest/html/users_guide/release-5-04.htm
l
How to get it
~
The easy way is to go to the WWW page, which should be self-explanatory:
http://www.haskell.org/ghc/
We supply binary builds in the native package format for various
flavours of Linux and BSD, and in InstallShield form for Windows
folks. Binary builds for other platforms are available as a .tar.gz
which can be installed wherever you want. The source distribution is
also available from the same place.
Once you have the distribution, please follow the pointers in the
README file to find all of the documentation about this release.
Background
~~
Haskell is a standard lazy functional programming language; the
current language version is Haskell 98, agreed in December 1998.
GHC is a state-of-the-art programming suite for Haskell. Included is
an optimising compiler generating good code for a variety of
platforms, together with an interactive system for convenient, quick
development. The distribution includes space and time profiling
facilities, a large collection of libraries, and support for various
language extensions, including concurrency, exceptions, and foreign
language interfaces (C, whatever). GHC is distributed under a
BSD-style open source license.
A wide variety of Haskell related resources (tutorials, libraries,
specifications, documentation, compilers, interpreters, references,
contact information, links to research groups) are available from the
Haskell home page (see below).
On-line GHC-related resources
~~
Relevant URLs on the World-Wide Web:
GHC home page http://www.haskell.org/ghc/
Haskell home page http://www.haskell.org/
comp.lang.functional FAQ http://www.cs.nott.ac.uk/~gmh/faq.html
System requirements
~~~
To compile programs with GHC, you need a machine with 64+MB memory, GCC
and perl. This release is known to work on the following platforms:
* i386-unknown-{linux,*bsd,mingw32}
* sparc-sun-solaris2
* alpha-dec-osf3
* powerpc-apple-darwin (MacOS/X)
Ports to the following platforms should be relatively easy (for a
wunderhacker), but haven't been tested due to lack of time/hardware:
* hppa1.1-hp-hpux{9,10}
* i386-unknown-solaris2
* mips-sgi-irix{5,6}
* {rs6000,powerpc}-ibm-aix
The builder's guide on the web site gives a complete run-down of what
ports work; it can be found at

fun with sockets (ghc-5.04.1)
Hi, I'm running into a problem using server code (running on a UNIX domain socket) that I basically snatched from Simon Marlow's web server: ++ mainLoop sock defUser getMs = do putStrLn Accepting connections... installHandler sigPIPE Ignore Nothing loop (0::Int) where loop n = do (connection, peerAddress) - accept sock h - socketToHandle connection ReadWriteMode forkIO ( (talk n getMs defUser h `finally` goodBye n h) `Exception.catch` (\e - putStrLn (Exception: ++ show e)) ) loop (n+1) goodBye n h = do putStrLn (show n ++ : finished) hClose h ++ After processing a random number of connections, the server dies with Fail: invalid argument Action: accept Reason: Invalid argument after finishing the last connection. For the record, here is the code that is executed for each connection: ++ talk n getMs user h = do hSetBuffering h LineBuffering putStrLn (show n ++ : ) str - hGetLine h lstr - hGetLine h putStrLn (...: ++ lstr) -- last output before core dump let msglength = read (takeWhile isDigit (drop 1 lstr)) rawmsg - hGetContents h putStrLn (Got ++ show (length msg) ++ characters) ++ The machine is Linux kailua 2.4.18-4GB #1 Wed Mar 27 13:57:05 UTC 2002 i686 unknown The problem seems to go away if I switch to INET sockets, so I'm also including my initialization code: ++ withSocketsDo $ do sock - socket AF_UNIX Stream 0 bindSocket sock (SockAddrUnix path) listen sock maxListenQueue getMs - initializeAll mainLoop sock defUser getMs ++ -Peter ___ Glasgow-haskell-users mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-users

After all, the reason for patchlevel releases is that you've fixed some bugs, so why be so secretive about what these fixes are?-) The release notes doesn't contain bugfixes, and the reason we don't have a list of them is because I'm too lazy to keep track of what bug fixes have been merged in, sorry! The Network fix wasn't merged in (just too late). Ok, I'll take a look at the diffs and summarise the fixes... here goes: - Literal strings could be duplicated sometimes - fixes for deriving Eq/Enum on large datatypes in GHCi - -no-hs-main has a sensible meaning in --make mode now (it forces linking even if there's no Main) - Fix for avoiding recompilation when there are stub files around (didn't pick up the stubs properly before) - Fixes for FFI decls containing type variables - MacOS X fixes for GHCi - Filenames with spaces don't cause problems in GHCi now - GHCi doesn't get confused if your code installs a signal handler for ^C - -pgmL now works as advertised - specifying filenames without the trailing .hs/.lhs works again in --make and GHCi. - Fix for class ops that do not introduce foralls (a cause of crashes with certain kinds of class methods). - Fix a crash when a class op is used as a record selector - Fix for deriving on records with fields with names with leading underscores. - Fixes for passing/returning FunPtr in the FFI - hsc2hs works in a binary distribution - Fixes for crashes in the biographical and retainer profilers. - Some signals were inadvertently blocked by the RTS - Uninitialised variable in the storage manager causes crashes - Fix for hp2ps -c - hsc2hs should now work on Windows - Fix off-by-one in Data.PackedString.splitWithPS - uninitialised elements in UArrays are now filled with zero. - Integer divide by zero is now consistently a catchable exception (previously it could just result in SIGFPE). - Fix for terminal buffering on Solaris - System.Console.GetOpt fixes - Fix for converting Integer to Int64/Word64 - Network.accept doesn't fail if the host fails to reverse-lookup.

Re: 5.04.2 RPM Dependencies
I tried the RPM for 7.2 and it seemed to work with --force and --nodeps (it asked for libreadline.so.4 which was already there).

Re: Effect of large binaries on garbage collection

I wonder how it is for a random FFI user to discover this. Does some advice belong in the FFI spec, or in GHC's FFI chapter?
