I was thinking of a dict or list _global_ to the
StreamRequestHandler.handle() method. That way I can pass the info on
with every new connection where the server will have access to it.

That's what I had in mind thanks. The server needs to keep track of all
the connected clients.

Sounds like it but isn't. I'm busy developing a test/mock harness for a
financial switch. Currently it caters only for messages from the client
to the harness and then back. I need to add functionality that when an
_external_ message arrives, the switch can determine which client it
needs to send the data to.

Many thanks

A specific socket can be used from every thread of a process. Just make 
sure that you synchronize everything.

I need to create a client that can connect to server and then determine
how many other clients are connected, what the socket info is
When you accept a socket client, a new socket is created, so you cannot 
determine how many clients are connected to a socket. You have to create 
a data structure where you insert info about accepted connections and 
delete the info when a connection is closed.

(ifile/ofile) and then send and receive specific data to those clients. 
ifile/ofile are local to the server process so you cannot use them to 
send data from one client to another client. You have to send the data 
to the server first with a special tag, the server has to use that tag 
and send the data to the designated other client.

It sounds a bit as if you want to build some kind of chat server and now 
you want to add private channels.

inter threading info

[Tertius Cronje]

Hi All,

Q: Is it possible for a thread on SocketServer.ThreadingTCPServer to get
the socket info of *other* open thread/s and use that info to send data
to the accepting client?

I wrote a socketserver using SocketServer.ThreadingTCPServer. A client
is connected to the server and expects multiple request/responses. (Not
sure about the terminology but the client connects and then stay
connected for a while.)

I need to create a client that can connect to server and then determine
how many other clients are connected, what the socket info is
(ifile/ofile) and then send and receive specific data to those clients. 

TIA
