[Python-Dev] Using Python on a fork-less POSIX-like OS
Hello Python list, I intend to cross-compile Python v3.6.6 to Threos ( https://threos.io ) operating system. Threos is supports a quite large set from POSIX and C89/C99. Unfortunately, Threos lacks fork(2), but provides posix_spawn(3) instead. I already made some local changes in posixmodule.c to compile due to some features are detected as present but actually not supported, like HAVE_FORK -- I blame autotools for this :-). I don't know, however, whether the Python shall cross-compile without issues. My question is that the _posixsubprocess.c can be prepared to use posix_spawn(3) instead of fork(2)? Maybe the UNIX/Linux version can also benefit from it, see: https://salsa.debian.org/ruby-team/ruby-posix-spawn Best regards, Aron ___ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

I would like to see it used whenever possible instead of fork+exec, since it's faster and it can be safer on some platforms. Pablo Salgado is your guy for that. Victor Awesome! Will this backported to 2.7? Or people should forget 2.7?
