Hi Ray,
Your code appears to work fine for me. I am using an updated version
of stackless socket, but the changes are superficial and only affect
UDP related usage.
The client consistently prints the following:
C:\Users\richardt\Stackless>sl27\PCbuild\python_d.exe client.py
Attempting to connect
pong
Connected to google
Note that your server code should be cause for alarm, just by reading it:
def run_server():
...
server = SimpleXMLRPCServer(("localhost", 8888), allow_none=True)
server.register_function(ping, "ping")
server.serve_forever()
The call in a tasklet to "serve_forever" implies you are invoking a
framework. And indeed, looking at the implementation shows that this
has an effect on any other tasklets:
def serve_forever(self, poll_interval=0.5):
...
while not self.__shutdown_request:
...
r, w, e = select.select([self], [], [], poll_interval)
...
Nothing within this yields to the scheduler. And additionally, it
will block for half a second waiting for socket activity. If you use
this without making it scheduler friendly, then you might as well not
use any Stackless functionality on the server side.
But back to the point, your code runs fine for me.
Cheers,
Richard.
