New submission from STINNER Victor <vstin...@python.org>:
I propose to add PyConfig._isolated_interpreter configuration parameter to disallow threads, subprocesses and fork in a subinterpreter. _xxsubinterpreter.create() gets a new keyword-only isolated=True parameter to opt-in for not isolated mode, which is the current behavior of Py_NewInterpreter(). For example, mod_wsgi would continue to run in "non isolated" mode. Attached PR implements this change. With the change, os.fork() is allowed again in "non isolated" subinterpreters (like mod_wsgi). os.fork() was disallowed in subinterpreters in Python 3.8, but subprocess was still allowed. ---------- components: Interpreter Core messages: 367778 nosy: vstinner priority: normal severity: normal status: open title: Add PyConfig._isolated_interpreter: isolated subinterpreters versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40453> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
