I'm discussing with Pablo to see how to use posix_spawn() in the Python subprocess module. IMHO we should consider the specific case of subprocess. What is the expected API? kw = {} if hasattr(os, 'POSIX_SPAWN_USEVFORK'): kw['flags'] = os.POSIX_SPAWN_USEVFORK posix_spawn(*args, **kw) or posix_spawn(*args, use_vfork=True) or kw = {} if sys.platform == 'linux': kw['use_vfork'] = True posix_spawn(*args, **kw) ? For example, if we consider that it's safe to use POSIX_SPAWN_USEVFORK in all cases for posix_spawn(), maybe we should not add an option at the Python level, and hardcode the POSIX_SPAWN_USEVFORK flag in the C code? -- > if I read the code correctly POSIX_SPAWN_USEVFORK is no longer used in the > implementation of posix_spawn(3)) Ok, now I'm confused: what's the point of this issue if the flag became useless? :-) ---------- _______________________________________ 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
