* [3.12] gh-119821: Support non-dict globals in LOAD_FROM_DICT_OR_GLOBALS ↵Jelle Zijlstra2024-06-012-329/+341
| | | | | | | | | | | (#119822) (#119890) The implementation basically copies LOAD_GLOBAL. Possibly it could be deduplicated, but that seems like it may get hairy since the two operations have different operands. This is important to fix in 3.14 for PEP 649, but it's a bug in earlier versions too, and we should backport to 3.13 and 3.12 if possible.

* [3.12] gh-119585: Fix crash involving `PyGILState_Release()` and ↵Sam Gross2024-05-311-0/+6
| | | | | | | | | | | `PyThreadState_Clear()` (GH-119753) (#119861) Make sure that `gilstate_counter` is not zero in when calling `PyThreadState_Clear()`. A destructor called from `PyThreadState_Clear()` may call back into `PyGILState_Ensure()` and `PyGILState_Release()`. If `gilstate_counter` is zero, it will try to create a new thread state before the current active thread state is destroyed, leading to an assertion failure or crash.

* [3.12] gh-119213: Be More Careful About _PyArg_Parser.kwtuple Across ↵Eric Snow2024-05-221-0/+17
| | | | | | | | | | | Interpreters (gh-119331) (gh-119425) _PyArg_Parser holds static global data generated for modules by Argument Clinic. The _PyArg_Parser.kwtuple field is a tuple object, even though it's stored within a static global. In some cases the tuple is statically allocated and thus it's okay that it gets shared by multiple interpreters. However, in other cases the tuple is set lazily, allocated from the heap using the active interprepreter at the point the tuple is needed. This is a problem once that interpreter is destroyed since _PyArg_Parser.kwtuple becomes at dangling pointer, leading to crashes. It isn't a problem if the tuple is allocated under the main interpreter, since its lifetime is bound to the lifetime of the runtime. The solution here is to temporarily switch to the main interpreter. The alternative would be to always statically allocate the tuple. This change also fixes a bug where only the most recent parser was added to the global linked list. (cherry picked from commit 81865002aee8eaaeb3c7e402f86183afa6de77bf)

This is important when heap types are registered, which is something we haven't been doing yet but I will likely do soon. (cherry-picked from commit 80dc39e1dc2abc809f448cba5d2c5b9c1c631e11)

* [3.12] gh-106931: Intern Statically Allocated Strings Globally (gh-107272) ↵Eric Snow2023-11-271-0/+7
| | | | | | | | | (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)
