* [3.12] gh-119213: Be More Careful About _PyArg_Parser.kwtuple Across ↵Eric Snow2024-05-224-0/+6
| | | | | | | | | | | 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)

* [3.12] gh-116767: fix crash on 'async with' with many context managers ↵Irit Katriel2024-05-011-1/+1
| | | | | | | | | | | | (GH-118348) (#118477) gh-116767: fix crash on 'async with' with many context managers (GH-118348) Account for `add_stopiteration_handler` pushing a block for `async with`. To allow generator functions that previously almost hit the `CO_MAXBLOCKS` limit by nesting non-async blocks, the limit is increased by 1. This increase allows one more block in non-generator functions. (cherry picked from commit c1bf4874c1e9db2beda1d62c8c241229783c789b)

* [3.12] gh-110310: Add a Per-Interpreter XID Registry for Heap Types ↵Eric Snow2023-11-282-19/+29
| | | | | | | | | | | | | | | (gh-110311) (gh-110714) We do the following: * add a per-interpreter XID registry (PyInterpreterState.xidregistry) * put heap types there (keep static types in _PyRuntimeState.xidregistry) * clear the registries during interpreter/runtime finalization * avoid duplicate entries in the registry (when _PyCrossInterpreterData_RegisterClass() is called more than once for a type) * use Py_TYPE() instead of PyObject_Type() in _PyCrossInterpreterData_Lookup() The per-interpreter registry helps preserve isolation between interpreters. 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)

| | | | | | | | | (gh-109921) (gh-110707) The existence of background threads running on a subinterpreter was preventing interpreters from getting properly destroyed, as well as impacting the ability to run the interpreter again. It also affected how we wait for non-daemon threads to finish. We add PyInterpreterState.threads.main, with some internal C-API functions.

* [3.12] gh-106931: Intern Statically Allocated Strings Globally (gh-107272) ↵Eric Snow2023-11-275-1/+12
| | | | | | | | | (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)
