You should use `_PyUnicode_InternImmortal` instead: - Strings should be interned before immortalization, otherwise you're possibly interning a immortalizing copy. - `_Py_SetImmortal` doesn't handle the `SSTATE_INTERNED_MORTAL` to `SSTATE_INTERNED_IMMORTAL` update, and those flags can't be changed in backports, as they are now part of public API and version-specific ABI. * Add private `_only_immortal` argument for `sys.getunicodeinternedsize`, used in refleak test machinery. Make sure the statically allocated string singletons are unique. This means these sets are now disjoint: - `_Py_ID` - `_Py_STR` (including the empty string) - one-character latin-1 singletons Now, when you intern a singleton, that exact singleton will be interned. * Add a `_Py_LATIN1_CHR` macro, use it instead of `_Py_ID`/`_Py_STR` for one-character latin-1 singletons everywhere (including Clinic). * Intern `_Py_STR` singletons at startup. * Beef up the tests. Cover internal details (marked with `@cpython_only`). * Add lots of assertions * Don't immortalize in PyUnicode_InternInPlace; keep immortalizing in other API (GH-121364) * Switch PyUnicode_InternInPlace to _PyUnicode_InternMortal, clarify docs * Document immortality in some functions that take `const char *` This is PyUnicode_InternFromString; PyDict_SetItemString, PyObject_SetAttrString; PyObject_DelAttrString; PyUnicode_InternFromString; and the PyModule_Add convenience functions. Always point out a non-immortalizing alternative. * Don't immortalize user-provided attr names in _ctypes * Immortalize names in code objects to avoid crash (GH-121903) * Intern latin-1 one-byte strings at startup (GH-122303) There are some 3.12-specific changes, mainly to allow statically allocated strings in deepfreeze. (In 3.13, deepfreeze switched to the general `_Py_ID`/`_Py_STR`.) Co-authored-by: Eric Snow <ericsnowcurrently@gmail.com>

* [3.12] gh-116510: Fix a crash due to shared immortal interned strings. ↵Neil Schemenauer2024-09-272-6/+47
| | | | | | | | | (gh-124541) Fix a crash caused by immortal interned strings being shared between sub-interpreters that use basic single-phase init. In that case, the string can be used by an interpreter that outlives the interpreter that created and interned it. For interpreters that share obmalloc state, also share the interned dict with the main interpreter.

* [3.12] gh-115528: Update language reference for PEP 646 (GH-121181) (#124633)Miss Islington (bot)2024-09-262-17/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gh-115528: Update language reference for PEP 646 (GH-121181) To recap: the objective is to make starred expressions valid in `subscription`, which is used for generics: `Generic[...]`, `list[...]`, etc. What _is_ gramatically valid in such contexts? Seemingly any of the following. (At least, none of the following throw `SyntaxError` in a 3.12.3 REPL.) Generic[x] Generic[*x] Generic[*x, y] Generic[y, *x] Generic[x := 1] Generic[x := 1, y := 2] So introducting flexible_expression: expression | assignment_expression | starred_item end then switching `subscription` to use `flexible_expression` sorts that. But then we need to field `yield` - for which any of the following are apparently valid: yield x yield x, yield x, y yield *x, yield *x, *y Introducing a separate `yield_list` is the simplest way I've been figure out to do this - separating out the special case of `starred_item ,`.

| | | | | | | | | | | | (#123957) gh-108951: Document how to terminate an asyncio.TaskGroup (GH-123837) We don't want to add another API, since the recipe is straightforward and rarely needed. The advantage is that we could backport this to the earliest Python version that has taskgroups (3.11, alas in security mode already, so we'll just do 3.12 and 3.13).
