Unable to reload python socket.send

Question

As we can see, the sending method is not overloaded.

from socket import socket

class PolySocket(socket):

    def __init__(self,*p):
        print "PolySocket init"
        socket.__init__(self,*p)

    def sendall(self,*p):
        print "PolySocket sendall"
        return socket.sendall(self,*p)

    def send(self,*p):
        print "PolySocket send"
        return socket.send(self,*p)


    def connect(self,*p):
        print "connecting..."
        socket.connect(self,*p)
        print "connected"

HOST="stackoverflow.com"   
PORT=80
readbuffer=""

s=PolySocket()
s.connect((HOST, PORT))
s.send("a")
s.sendall("a")

Output:

PolySocket init
connecting...
connected
PolySocket sendall

I am sure that you really do not need this, and there are other ways to solve your problem (not subclasses, but the real problem).

If you really need to make fun of the object, go to the proxy object:

from socket import socket


class PolySocket(object):
    def __init__(self, *p):
        print "PolySocket init"
        self._sock = socket(*p)

    def __getattr__(self, name):
        return getattr(self._sock, name)

    def sendall(self, *p):
        print "PolySocket sendall"
        return self._sock.sendall(*p)

    def send(self, *p):
        print "PolySocket send"
        return self._sock.send(*p)

    def connect(self, *p):
        print "connecting..."
        self._sock.connect(*p)
        print "connected"

HOST = "stackoverflow.com"
PORT = 80
readbuffer = ""

s = PolySocket()
s.connect((HOST, PORT))
s.send("a")
s.sendall("a")

Here's the conclusion:

% python foo.py
PolySocket init
connecting...
connected
PolySocket send
PolySocket sendall
