* [3.12] gh-117482: Fix the Slot Wrapper Inheritance Tests (gh-122250)Eric Snow2024-07-291-4/+19
| | | | | The tests were only checking cases where the slot wrapper was present in the initial case. They were missing when the slot wrapper was added in the additional initializations. This fixes that. (cherry-picked from commit 490e0ad83ac72c5688dfbbab4eac61ccfd7be5fd, AKA gh-122248)
* [3.12] gh-117482: Simplify the Fix For Builtin Types Slot Wrappers (gh-122241)Eric Snow2024-07-241-30/+92
| | | | | | | | | | | | | | | | | In gh-121602, I applied a fix to a builtin types initialization bug. That fix made sense in the context of some broader future changes, but introduced a little bit of extra complexity. For earlier versions those future changes are not relevant; we can avoid the extra complexity. Thus we can revert that earlier change and replace it with this one, which is more focused and conceptually simpler. This is essentially the implementation of an idea that @markshannon pointed out to me. Note that this change would be much smaller if we didn't have to deal with repr compatibility for builtin types that explicitly inherit tp slots (see expect_manually_inherited()). The alternative is to stop *explicitly* inheriting tp slots in static PyTypeObject values, which is churn that we can do separately.

* [3.12] gh-117482: Fix Builtin Types Slot Wrappers (gh-121632)Eric Snow2024-07-111-9/+32
| | | | | | | When builtin static types are initialized for a subinterpreter, various "tp" slots have already been inherited (for the main interpreter). This was interfering with the logic in add_operators() (in Objects/typeobject.c), causing a wrapper to get created when it shouldn't. This change fixes that by preserving the original data from the static type struct and checking that.

| | | | | | | | | | | | | | exit (GH-116677) (#117029) Starting in Python 3.12, we prevented calling fork() and starting new threads during interpreter finalization (shutdown). This has led to a number of regressions and flaky tests. We should not prevent starting new threads (or `fork()`) until all non-daemon threads exit and finalization starts in earnest. This changes the checks to use `_PyInterpreterState_GetFinalizing(interp)`, which is set immediately before terminating non-daemon threads.

* [3.12] gh-106931: Intern Statically Allocated Strings Globally (gh-107272) ↵Eric Snow2023-11-271-3/+69
| | | | | | | | | (gh-110713) We tried this before with a dict and for all interned strings. That ran into problems due to interpreter isolation. However, exclusively using a per-interpreter cache caused some inconsistency that can eliminate the benefit of interning. Here we circle back to using a global cache, but only for statically allocated strings. We also use a more-basic _Py_hashtable_t for that global cache instead of a dict. Ideally we would only have the global cache, but the optional isolation of each interpreter's allocator means that a non-static string object must not outlive its interpreter. Thus we would have to store a copy of each such interned string in the global cache, tied to the main interpreter. (cherry-picked from commit b72947a8d26915156323ccfd04d273199ecb870c)
