* [3.13] gh-122527: Fix a crash on deallocation of `PyStructSequence` ↵Miss Islington (bot)2024-09-021-6/+22
| | | | | | | | | | | | | | | | | | | | (GH-122577) (#122625) gh-122527: Fix a crash on deallocation of `PyStructSequence` (GH-122577) The `PyStructSequence` destructor would crash if it was deallocated after its type's dictionary was cleared by the GC, because it couldn't compute the "real size" of the instance. This could occur with relatively straightforward code in the free-threaded build or with a reference cycle involving the type in the default build, due to differing orders in which `tp_clear()` was called. Account for the non-sequence fields in `tp_basicsize` and use that, along with `Py_SIZE()`, to compute the "real" size of a `PyStructSequence` in the dealloc function. This avoids the accesses to the type's dictionary during dealloc, which were unsafe.

| | | | | | | | | | | | | | | | | (GH-123052) (#123114) Check that the current default heap is initialized in `_mi_os_get_aligned_hint` and `mi_os_claim_huge_pages`. The mimalloc function `_mi_os_get_aligned_hint` assumes that there is an initialized default heap. This is true for our main thread, but not for background threads. The problematic code path is usually called during initialization (i.e., `Py_Initialize`), but it may also be called if the program allocates large amounts of memory in total. The crash only affected the free-threaded build. (cherry picked from commit d061ffea7b408861d0a9d311e92c363da284971d) Co-authored-by: Sam Gross <colesbury@gmail.com>

* [3.13] gh-117482: Simplify the Fix For Builtin Types Slot Wrappers (gh-121932)Eric Snow2024-07-241-30/+93
| | | | | | | | | | | | | | | 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.

* [3.13] gh-117482: Fix Builtin Types Slot Wrappers (gh-121630)Miss Islington (bot)2024-07-111-10/+30
| | | | | | | 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.
