Colm Buckley added the comment: It's worth noting that this issue now affects every installation of Debian testing track with systemd and systemd-cron installed; the python program /lib/systemd/system-generators/systemd-crontab-generator is called very early in the boot process; it imports hashlib (although only .md5() is used) and blocks on getrandom(), delaying boot time until a 90s timeout has occurred.
Suggestions: modify hashlib to avoid calling getrandom() until entropy is actually required, rather than on import; change the logic to use /dev/urandom (or an in-process PRNG) when getrandom() blocks; or both. ---------- nosy: +Colm Buckley _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26839> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
