[Twisted-Python] Using win32eventreactor (newbie alert)
by Jeff Grimmett Feb. 2, 2003

Feb. 2, 2003

Relatively new twisted user here :-) I'm a little confused about how to use the win32eventreactor in place of the default. The default on W32 platforms doesn't have the ProcessProtocol support implemented yet, but according to the docs the win32eventreactor does. Here's what I need to do: I want to listen on one or more ports for connections; when connections are made, I want to connect these connections with programs designed to handle the connection in question, i.e. if it's telnet I want to connect the session with a login program and proceed from there. I haven't gotten that far yet but from what I've seen so far I *think* I will need to support the ProcessProtocol and tie the telnet to it. I could be wrong on this but I'm trying to think ahead. So back to win32eventreactor; imply using .install() doesn't get me the ability to use the ProcessProtocol. So I tried replacing the default reactor with win32eventreactor completely; I got errors regarding connectTCP when I did this. So I'm stumped for the moment. I'm sure I'm making some very simple mistake somewhere. A gentle shove in the right direction would be greatly appreciated. Oh, and to the twisted team, compliments on the package. It's wonderful.

[Twisted-Python] Webchat
by Achim Domma Feb. 2, 2003

Feb. 2, 2003

Hi, I'm new to Twisted an want to understand a little bit more what it can do for me. I have implemented a webchat using the asyncore module. If a user logs in, he will the redirected to a frameset. The top frame contains the 'room view' and is in fact an endless page, so the connection has to be keept alive as long as the user is logged in. The bottom frame contains the input form. It posts a message to the server and the message is written to the open connections of all users in the room. Could somebody explain me, if such an architecture is possible with Twisted, and what might be the benefits compared to using raw asyncore. If possible a very rought roadmap how to begin would also be very helpfull. regards, Achim

Or is it safe to assume that service names for ports will always be ascii (in which case we change that to "if port == types.StringTypes")? -Andrew.
