Hi,
I'm trying to implement an IWriteDescriptor using raw sockets.
So far this is what I wrote... but it doesn't work:
https://github.com/david415/hushTCP/blob/master/hush_writer.py
Am I doing something obviously wrong here?
I certainly am able to use raw socket + scapy correctly without
Twisted.
Please describe the problem in more detail than "it doesn't work". >:)
Your hush_writer.py is a good <http://sscce.org/> but it's still
important to know how its behavior differs from your expectations.
As far as I can tell it does work - although there's one mistake that
makes it a bit more inefficient than strictly necessary:
def doWrite(self):
if len(self.packets) > 0:
self.socket.sendto(self.packets.pop(0), self.address)
else:
return
When you're out of packets you should remove the writer from the
reactor. This version of the code will perpetually dispatch writeable
notification (in the form of a doWrite call) to your object as fast as
possible.
Once you fix this, don't forget to re-add the writer as soon as
len(self.packets) rises above 0 again.
