You might want to run the process under ProcMon and see if you can
figure out what's going on (if you can bear to use ProcMon, it's a
very poor replacement for strace IMO).
You could try StraceNT instead (not as good as strace though).
As I understand it, programs compiled with GHC currently use MSYS for all
I/O operations, resulting in all kinds of strange behaviour in corner cases.
(E.g., if you use System.Directory and ask whether C:\\ is a directory, it
says no, yet you can read the contents of that directory.) I would
Hi all,
winio is an I/O library for Windows using Windows API functions and
has I/O completion port support. The main goal of this library is to
support Simon Marlow's new Handle API once he has added that to GHC.
The library also has a compatibility module for socket functions from

The Network.Socket module works fine on Windows. The original Winsock
implementation was based on the Berkeley sockets api.

May i suggest Johan Tibell's web application interface (see

Hyena can then be used as an application server and frameworks won't
have to create their own servers. Many people have different opinions

There is currently a discussion on reddit/programming about Haskell.
One complaint is that Haskell functions often use abbreviated names. I
tend to agree with that. In my personal experience it generally takes

Hi John,
You don't have to compile hsc2hs yourself. It is part of the standard
GHC installation. Cabal should be able to find it. You can check if it
does by running runghc Setup.hs configure -v when configuring a
package. Compiling network-2.2.0.0 against parsec-3.0.0 with
msys/mingw worked fine
and Windows support is less of an issue: git appears to work reasonably well
on Windows these days.
Congratulations on the switch, but isn't the decision a bit premature?
I have read the log of last week's GHC meeting on IRC and nobody
seemed to know if Git runs well on Windows with a large
