bpo-46583: remove unused sys.version_info check from selectors (GH-31023) 2022-02-02 10:15:02 +02:00

bpo-41182 selector: use DefaultSelector based upon implementation (GH-21257) 
On some platform such as VMware ESXi, DefaultSelector fails
to detect selector due to default value.
This fix adds a check and uses the correct selector depending upon
select implementation and actual call.

Fixes: [bpo-41182]()

bpo-29255: Wait in KqueueSelector.select when no fds are registered (GH-19508) 
Also partially fixes bpo-25680 (there's still a discrepancy in behavior
on Windows that needs to be fixed).

f70e1ca0fc Issue #23485: select.select() is now retried automatically with the recomputed 
timeout when interrupted by a signal, except if the signal handler raises an
exception. This change is part of the PEP 475.

The asyncore and selectors module doesn't catch the InterruptedError exception
anymore when calling select.select(), since this function should not raise
InterruptedError anymore.

567b26e882 Issue #20311: EpollSelector now also rounds the timeout towards zero, as 
PollSelector.

This change is not really required in Python 3.4, since select.epoll.poll() now
rounds also correctly the timeout. But Guido van Rossum prefers to have exactly
the same selectors.py file in CPython and Tulip projects: "it's not harmful".

11da8e24ba Issue #20311: selector.PollSelector.select() now rounds the timeout away from 
zero, instead of rounding towards zero. For example, a timeout of one
microsecond is now rounded to one millisecond, instead of being rounded to
zero.

Move also a test in test_epoll which was moved by my previous merge.
