Comment:

 FWIW, I think `liftM fst` is clearer than `return . fst =<< `.

Comment (by tphyahoo):

 Also, for what it's worth, a quick and dirty fix which at least keeps
 happs apps from dying is simply to turn off ipv6 support like so:

 {{{
 diff -rN old-network-2.2.0.1/Network.hs new-network-2.2.0.1/Network.hs
 22c22
 < #define IPV6_SOCKET_SUPPORT 1
 ---
 > # /* define IPV6_SOCKET_SUPPORT 1 */
 }}}

Comment (by tphyahoo):

 Yes, not a very good patch I agree. I had an uncaught exception error a
 couple of days after I implemented.

 Anyway, here's a tweaked patch, which at least fixes that.


 {{{
 <  (Just peer, _) <- getNameInfo [] True False addr
 ---
 >  (Just peer) <-
 > catchIO ( return . fst =<< getNameInfo [] True False addr )
 > (\e -> case addr of
 >  SockAddrInet port haddr -> return . Just =<<
 inet_ntoa haddr
 >  SockAddrInet6 port flow haddr6 scope -> return .
 Just . show $ haddr6
 >  SockAddrUnix x -> return . Just $ x
 > )
 >
 }}}

Comment:

 The bug seems legitimate. Thanks for reporting it. The patch is a bit
 crufty, so I'll work something cleaner up.

 There is an uncaught exception in the network library which is causing
 my HAppS demo website

 http://happstutorial.com

 to crash every couple of days. This has affected other people using
 HAppS as well, as described on postings to the HAppS users list.

 The bug, and workarounds, is described at

 http://code.google.com/p/happs/issues/detail?id=40

 Initially reported patch at

 http://www.haskell.org/pipermail/libraries/2009-January/011103.html

 Patch is attached.
