Real handling of network errors.
Fix for correctly ignoring net errors: It seems that (at least in
my installed Debian version of python2.4) socket.error does not have an
errno attribute but is simply a tuple of (errno, strerror). So we now
try to get errno first and if this fails we try to use err [0]. This
works for a simple test-script to which I can connect with telnet on
port 4711 -- it will correctly detect errno.EPIPE if I terminate the
telnet session:
#!/usr/bin/python2.4
import socket
import errno
from SocketServer import TCPServer, BaseRequestHandler
class Server (BaseRequestHandler) :
def handle (self) :
self.file = self.request.makefile ()
try :
while True :
print >> self.file, "Testing..."
except socket.error, err :
print getattr (err, 'errno', "Has no errno")
print err [0]
print err [0] == errno.EPIPE
raise
# end def handle
# end class Server
server_address = ('', 4711)
s = TCPServer (server_address, Server)
s.serve_forever ()
Sorry for the verbose log-message but I hope to document my debugging
activities
