We can reimplement os.urandom in SystemRandom on UNIX to keep the file (fd) open. The code is very simple, basically it's just a call to file.read(n). Adding a randbytes() method in Python 3.5 would be nice. The io module can handle boring things for you, like calling read in a loop until you get enough bytes and handle InterruptError. Except if you would prefer to use os.read or FileIO.read to avoid readahead. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21305> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
