Giampaolo Rodola' added the comment:
Follows a couple of minor concerns.
- What about Solaris' /dev/poll?
- I'm not sure why in case of EINTR you retry with a different timeout; can't
you just return []?
- this is probably because I'm paranoid about performances but given that
select() method will be called repeatedly I would not use a decorator. Also,
similarly to what has been done elsewhere in the stdlib, for "critical" parts I
would recommend localizing variable access in order to minimize overhead as in:
def select(self, timeout=None):
...
key_from_fd = self._key_from_fd
ready_append = ready.append
for fd in r | w:
...
key = key_from_fd(fd)
if key:
ready_append((key, events & key.events))
