There's a reason multiprocessing in spawn mode jumps through the hoops that it does: it's the only way to get __main__ pickling to work when you're not forking the entire process. You also don't want to naively re-run __main__ in the subprocess for the same reason multiprocessing doesn't: doing so would also re-run the script parts, not just the class and function definition parts. So while I don't think it should be implicit the way it is for multiprocessing spawn mode, I do think it would make sense to offer a way to explicitly opt-in to re-running __main__ in a child interpreter as "__si_main__", aliasing the subinterpreter's __main__ module to that, and also aliasing "__si_main__" to "__main__" in the parent interpreter. ---------- nosy: +ncoghlan _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37292> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
