Re: [Twisted-Python] “Unhandled Error” comes when TCP server tries to accept connections from client in twisted
You forgot to set the protocol attribute of the factory.
factory.protocol = ChatServer

[Twisted-Python] “Unhandled Error” comes when TCP server tries to accept connections from client in twisted
from twisted.internet.protocol import Factory,Protocolfrom
twisted.internet import reactor
class ChatServer(Protocol):
def connectionMade(self):
print "A Client Has Connected"
factory = Factory()
reactor.listenTCP(80,factory)print "Chat Server Started"
reactor.run()
the above code is running succesfully.but when I try to open
TCP(telnet localhost 80).
Errors occurs :
Unhandled ErrorTraceback (most recent call last):

sir/mam i have also discuss this question on stackoverflow ...but i
did'nt get any appropriate answer.

It would be good to raise this question on a different mailing list; one with lots of people with knowledge of internals of packaging tools. If any of them need clarification on the Twisted side of things, I'd be happy to expand and improve the question. -glyph ___ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python

[Twisted-Python] How do you write a setup.py that installs plugins?
Hi,
How are you supposed to write a setup.py that installs twistd plugins?
I have this piece of tribal knowledge:
from setuptools.command import egg_info
def _top_level(name):
return name.split('.', 1)[0]
def _hacked_write_toplevel_names(cmd, basename, filename):
names = map(_top_level, cmd.distribution.iter_distribution_names())
pkgs = dict.fromkeys(set(names) - set(["twisted"]))
cmd.write_file("top-level names", filename, '\n'.join(pkgs) + '\n')
egg_info.write_toplevel_names = _hacked_write_toplevel_names
---
But I don't actually know what's actually required, and I don't actually
know where this is documented (if at all). Plus, it looks pretty
unsanitary, and appears to introduce a dependency to setuptools.
So, how am I supposed to do this?
Thanks in advance
lvh
