STINNER Victor added the comment: Oh, sorry, I introduced the bug in Python 3.6 with the PEP 524 (os.urandom() now blocks on Linux). Too bad that there is no simple way to write an unit test for that.
> ... but only on Windows on Python 3.6 With the bug, or when the fix when _PyOS_URandomNonblock() fails, Random.seed() uses: * Reading system entropy failed, fall back on the worst entropy: use the current time and process identifier. */ random_seed_time_pid(self); It's just that on Windows, the system clock has a resolution around 15 ms, whereas it has a resolution better than 1 us on Linux. So it's just that calling Random.seed() usually takes longer than the resolution of the system clock on Linux :-) Not really that the bug is specific to Windows. Thanks for the fix Benjamin! ---------- nosy: +haypo _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29085> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
