[issue21372] multiprocessing.util.register_after_fork inconsistency
Marc Schlaich added the comment: Your statement is not correct, it does work on Windows (where fork is not available) if you register the hook on module level instead of in `__main__`. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21372 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue21372] multiprocessing.util.register_after_fork inconsistency
Richard Oudkerk added the comment: register_after_fork() is intentionally undocumented and for internal use. It is only run when starting a new process using the fork start method whether on Windows or not -- the fork in its name is a hint. -- resolution: - not a bug stage: - resolved status: open - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21372 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue21372] multiprocessing.util.register_after_fork inconsistency
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()
