But that doesn't cover the case for programs that don't fork and really just want to exec another program. when using subprocess, you'll always have two processes running. > If subprocess is used without pass_fds, > applications stops working since python 3.2 (since python 3.0 on > Windows). pass_fds will clear the close-on-exec flag on the file > descriptors with the PEP. If an application breaks because it relies > on file descriptor inherance, it's easy to detect it (EBADF error) and the application may open other files/sockets and the unused file descriptor would be reused. there's no EBADF in that case. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
