Re: readping fd's and flushing buffers

[Keean Schupke]

This may be related to the answer just given to do with finalizing the Handles, as I have a
problem with sockets hanging around after a host name resolution has failed (using the simple socket
library). Having looked at the code I would like to suggest the following change:

connectTo hostname (PortNumber port) = do
proto <- getProtocolNumber "tcp"
sock <- socket AF_INET Stream proto
he <- getHostByName hostname
connect sock (SockAddrInet port (hostAddress he))
socketToHandle sock ReadWriteMode

Should become:

connectTo hostname (PortNumber port) = do
proto <- getProtocolNumber "tcp"
sock <- socket AF_INET Stream proto
(do
he <- getHostByName hostname
connect sock (SockAddrInet port (hostAddress he))
socketToHandle sock ReadWriteMode) `Exception.catch` (\e -> do sClose sock;throw e)

Is this a sensible change to make?

Regards,
Keean Schupke.
