As mentioned on the other issue #25420, this is a regression and a change in documented behavior of os.urandom(), which is expected to be non-blocking, regardless of whether entropy is available or not. The fix should be easy (from reading the man page http://man7.org/linux/man-pages/man2/getrandom.2.html): set the GRND_NONBLOCK flag on getrandom(); then, if the function returns -1 and sets EAGAIN, fallback to reading from /dev/urandom directly. |
