Working code or it didn't happen. (And it should scale too.)
I have some (mostly) working code which replaces tulip's "pollster" classes with "proactor" classes for select(), poll(), epoll() and IOCP. See
The IOCP proactor does not support ssl (or ipv6) so main.py does not succeed in downloading from xkcd.com using ssl. Using the other proactors it works correctly.
The basic interface for the proactor looks like
class Proactor: def recv(self, sock, n): ... def send(self, sock, buf): ... def connect(self, sock, address): ... def accept(self, sock): ...
def poll(self, timeout=None): ... def pollable(self): ...
recv(), send(), connect() and accept() initiate io operations and return futures. poll() returns a list of ready futures. pollable() returns true if there are any outstanding operations registered with the proactor. You use a pattern like
f = proactor.recv(sock, 100) if not f.done(): yield from scheduling.block_future(f) res = f.result()
