[Pyobjc-dev] Question about Python sockets and NSFileDescriptors

[Jim C. <cl...@cs...>]

Hello,
	I've narrowed my problem down a bit more.  I'm wrapping a python  
socket in an NSFileDescriptor and then registering to receive  
ConnectionAccepted notifications.  When I run my code listed below I  
just get an infinite number of notifications.  Can anyone see any  
errors in my code or explain why I might be getting some many  
connection notices?

Thanks again,
	Jim

import socket

from Foundation import *
from AppKit import *
from PyObjCTools import NibClassBuilder, AppHelper

NibClassBuilder.extractClasses("MainMenu")

class TestServer(NibClassBuilder.AutoBaseClass):
     def awakeFromNib(self):
         sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
         sock.bind((socket.gethostname(), 0))
         sock.listen(1)

         # Wrap the socket in an NSFileHandle using fileno() to get the
         # file descriptor for the socket object
         listeningSocket =  
NSFileHandle.alloc().initWithFileDescriptor_(sock.fileno())

         # Register that we want to be informed of connection  
notifications
          
NSNotificationCenter.defaultCenter().addObserver_selector_name_object_(s 
elf, "handleConnectionNotification:",  
NSFileHandleConnectionAcceptedNotification, listeningSocket)
         listeningSocket.acceptConnectionInBackgroundAndNotify()

     def handleConnectionNotification_(self, aNotification):
         print "Got Connection"
         aNotification.object().acceptConnectionInBackgroundAndNotify()
