Can we please try to be clear about what kind of blocking we mean? getrandom(flags=0) absolutely *can* block: that's what the original issue was all about. To ensure it *never* blocks you need to call getrandom(GRND_NONBLOCK): that's why the flag exists. Put another way: - getrandom(flags=GRND_RANDOM) == /dev/random - getrandom(flags=GRND_NONBLOCK) == /dev/urandom on Linux - getrandom(flags=0) == /dev/urandom everywhere but Linux ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27266> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
