Nathaniel Smith added the comment: The attached script wakeup-fd-racer.py fails consistently for me using cpython 3.6.0 on my windows 10 vm:
> python wakeup-fd-racer.py Attempt 0: start Attempt 0: FAILED, took 10.016000000000076 seconds select_calls = 2 (It may help that the VM only has 1 CPU? But the same test passes on Linux even when I use taskset to restrict it to 1 cpu. Maybe Windows has some scheduling heuristic where one thread writing to a socket when another thread is blocked on it triggers an immediate context switch.) ---------- Added file: http://bugs.python.org/file46797/wakeup-fd-racer.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30038> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
