msgstr ""

#: ../../c-api/subinterpreters.rst:251

msgid ""

"Using :c:func:`Py_NewInterpreterFromConfig` you can create a sub-interpreter "

"that is completely isolated from other interpreters, including having its "

"own GIL. The most important benefit of this isolation is that such an "

"interpreter can execute Python code without being blocked by other "

"interpreters or blocking any others. Thus a single Python process can truly "

"take advantage of multiple CPU cores when running Python code. The "

"isolation also encourages a different approach to concurrency than that of "

"just using threads. (See :pep:`554` and :pep:`684`.)"

msgstr ""

#: ../../c-api/subinterpreters.rst:261

msgid ""

"Using an isolated interpreter requires vigilance in preserving that "

"isolation. That especially means not sharing any objects or mutable state "

"without guarantees about thread-safety. Even objects that are otherwise "

"immutable (e.g. ``None``, ``(1, 5)``) can't normally be shared because of "

"the refcount. One simple but less-efficient approach around this is to use "

"a global lock around all use of some state (or object). Alternately, "

"effectively immutable objects (like integers or strings) can be made safe in "

"spite of their refcounts by making them :term:`immortal`. In fact, this has "

"been done for the builtin singletons, small integers, and a number of other "

"builtin objects."

msgstr ""

msgid ""

"If you preserve isolation then you will have access to proper multi-core "

"computing without the complications that come with free-threading. Failure "

"to preserve isolation will expose you to the full consequences of free-"

"threading, including races and hard-to-debug crashes."

msgstr ""

#: ../../c-api/subinterpreters.rst:277

msgid ""

"Aside from that, one of the main challenges of using multiple isolated "

"interpreters is how to communicate between them safely (not break isolation) "

"and efficiently. The runtime and stdlib do not provide any standard "

"approach to this yet. A future stdlib module would help mitigate the effort "

"of preserving isolation and expose effective tools for communicating (and "

"sharing) data between interpreters."

msgstr ""

#: ../../c-api/subinterpreters.rst:286

msgid "Bugs and caveats"

msgstr ""

#: ../../c-api/subinterpreters.rst:288

msgid ""

"Because sub-interpreters (and the main interpreter) are part of the same "

"process, the insulation between them isn't perfect --- for example, using "

"low-level file operations like :func:`os.close` they can (accidentally or "

"maliciously) affect each other's open files. Because of the way extensions "

"are shared between (sub-)interpreters, some extensions may not work "

"properly; this is especially likely when using single-phase initialization "

"or (static) global variables. It is possible to insert objects created in "

"one sub-interpreter into a namespace of another (sub-)interpreter; this "

"should be avoided if possible."

msgstr ""

#: ../../c-api/subinterpreters.rst:298

msgid ""

"Special care should be taken to avoid sharing user-defined functions, "

"methods, instances or classes between sub-interpreters, since import "

"operations executed by such objects may affect the wrong (sub-)interpreter's "

"dictionary of loaded modules. It is equally important to avoid sharing "

"objects from which the above are reachable."

msgstr ""

#: ../../c-api/subinterpreters.rst:304

msgid ""

"Also note that combining this functionality with ``PyGILState_*`` APIs is "

"delicate, because these APIs assume a bijection between Python thread states "

"and OS-level threads, an assumption broken by the presence of sub-"

"interpreters. It is highly recommended that you don't switch sub-"

"interpreters between a pair of matching :c:func:`PyGILState_Ensure` and :c:"

"func:`PyGILState_Release` calls. Furthermore, extensions (such as :mod:"

"`ctypes`) using these APIs to allow calling of Python code from non-Python "
