In Python 3.8 the default start method has changed from fork to spawn on macOS. https://docs.python.org/3/whatsnew/3.8.html#multiprocessing get_all_start_methods() says: "Returns a list of the supported start methods, the first of which is the default." https://docs.python.org/3/library/multiprocessing.html?highlight=finalize#multiprocessing.get_all_start_methods However, it appears to still return fork as default: Python 3.8.1 (default, Dec 22 2019, 03:45:23) [Clang 10.0.1 (clang-1001.0.46.4)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import multiprocessing >>> multiprocessing.get_all_start_methods() ['fork', 'spawn', 'forkserver'] >>> Thank you! ---------- components: Library (Lib), macOS messages: 359503 nosy: ned.deily, ronaldoussoren, stefanholek priority: normal severity: normal status: open title: multiprocessing.get_all_start_methods() wrong default on macOS type: behavior versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39244> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
