[New-bugs-announce] [issue21372] multiprocessing.util.register_after_fork inconsistency

[Marc Schlaich]

New submission from Marc Schlaich:

multiprocessing.util.register_after_fork does not behave consistently on Windows because the `_afterfork_registry` is not transferred to the subprocess. The following example fails on Windows while it works perfectly on Linux:


import multiprocessing.util


def hook(*args):
    print (args)


def func():
    print ('func')


if __name__ == '__main__':
    multiprocessing.util.register_after_fork(hook, hook)
    p = multiprocessing.Process(target=func)
    p.start()
