This commit "bpo-16500: Allow registering at-fork handlers" adds the following code to Lib/random.py: +if hasattr(_os, "fork"): + _os.register_at_fork(_inst.seed, when='child') test_threaded_import creates fresh instance of the random module and so os.register_at_fork() is called multiple time with multiple different callbacks. The problem is that it's not currently possible to remove callbacks. It would be nice to be able to unregister callbacks, at least a private for unit tests. The minimum would be a os.unregister_at_fork() function. I would prefer to have get/set functions to be able to restore callbacks once tests complete, but also to detect when an unexpected callback was registered. For example, write a new test in Lib/test/libregrtest/save_env.py for regrtest. See also bpo-16500 which added the new API. ---------- nosy: +pitrou, serhiy.storchaka _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30599> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
