STINNER Victor added the comment: Larry Hastings (msg267818, on the issue #26839): > What is the default value of the "block" parameter?
False > If called with block=False on FreeBSD, where /dev/urandom may block > sometimes, what does the function do? The function blocks. In which case FreeBSD urandom can block? Is there a way to read from /dev/urandom without blocking? If not, _PyOS_URandom() may use arc4random() on FreeBSD if block is false. I suggest to enhance _PyOS_URandom() after the Python 3.5.2 release. My patch is a quick fix for Python 3.5.2, it can be enhanced later. I chose to only modify the behaviour on Linux since issues #26839 and #25420 were only reported on 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
