STINNER Victor <vstin...@redhat.com> added the comment:
subprocess still work in subinterpreters in Python 3.8 if posix_spawn() can be used, but posix_spawn() is only used under some conditions: https://docs.python.org/dev/whatsnew/3.8.html#optimizations "The subprocess module can now use the os.posix_spawn() function in some cases for better performance. Currently, it is only used on macOS and Linux (using glibc 2.24 or newer) if all these conditions are met: * close_fds is false; * preexec_fn, pass_fds, cwd and start_new_session parameters are not set; * the executable path contains a directory." -- It seems like FreeIPA uses ctypes and ctypes calls subprocess.Popen(['/sbin/ldconfig', '-p'], ...) to locale libcrypto. I see different options: * modify FreeIPA / ctypes to ensure that posix_spawn() can be used * avoid subinterpreters to deploy FreeIPA * revert the change to allow again fork in subprocesses: see bpo-34651 for the rationale why it was denied I understand that FreeIPA is run as WSGI using mod_wsgi in Apache. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37951> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
