Threads for a newbe

[Giraud, Sebastien]

First thx for Your answer :)

So here are my two codes :

The first which doesn't work - And the second which works (at last :) )
I cant say why the first one doesn't work...

In fact you'll see that it's my first time in Python AND in object
programming as well... There are lot's of error (like using variable instead
of using parameters) but I'll rewrite the source when I'll have understood
thread's, socket and object better... Maybe should I have started with an
easier project... ;)

Exceptions, protocol and high lvl user function are still missing. But i
just try to make a socket-server works at first.

If you have any advise or idea I'll be glad to read it :)

I recently did implement a socket-server using threads. So if you give me
more actual code, I might be able to help you.

However, I stepped away from that approach and went for twisted - a really
excellent networing framework, which eliminated the need for different
threads. You should really look into that, as just having different threads
sitting on blocking io-descriptors is abusing them (while I have to admit -
its tempting...)
