I have problems in getting a SocketServer to shutdown.
Do you want to do a shutdown or a close?
I want the server close the socket ...
You want to do a close, do a close, not a shutdown
<http://docs.python.org/library/socket.html>.
Shutdown implies closing the listening socket, doesn't it?
No (perhaps it should, but that is another issue). There is a
documentation bug; BaseServer.shutdown is documented as "Tells the
serve_forever() loop to stop and waits until it does." [1]
The docstring is much more explicit: """Stops the serve_forever loop.
Blocks until the loop has finished. This must be called while
serve_forever() is running in another thread, or it will deadlock."""
So, if you have a single-threaded server, *don't* use shutdown(). And, to
orderly close the listening socket, use server_close() instead. Your code
would become:
from SocketServer import TCPServer, BaseRequestHandler
server = TCPServer(('localhost',1234), BaseRequestHandler)
try:
server.serve_forever()
except KeyboardInterrupt:
print "^C detected"
pass
finally:
print "server_close()"
server.server_close()
print "bye"
(I've opened http://bugs.python.org/issue6031 )

Thanks, Gabriel, that's exactly what I was waiting for.
