Gregory: on Linux, it does change the behavior. The parent blocks until the child is spawned. Python should let the developer decide to opt-in. Serhiy: IMHO it's better to make posix_spawn() as dumb as possible, a simple wrapper to the C call. use_vfork=True is currently designed for the GNU constant. posix_spawn(use_vfork=True) raises on FreeBSD: only pass use_vfork=True on Linux. What do you think? The problem of changing the default is that we don't know the full list of all platforms that use vfork() by default. If we have a shoet list, how do we know if it's complete? For example, macOS doesn't say anything about vfork. Does it use it? Maybe not. Maybe yes. What if the default changes on a platform? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34663> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
