Peter Bierma	b275b8f342	gh-133140: Add PyUnstable_Object_IsUniquelyReferenced for free-threading (#133144)	2025-05-05 21:01:20 +02:00
Sam Gross	f2379535fe	gh-133164: Add PyUnstable_Object_IsUniqueReferencedTemporary C API (gh-133170) ... After gh-130704, the interpreter replaces some uses of `LOAD_FAST` with `LOAD_FAST_BORROW` which avoid incref/decrefs by "borrowing" references on the interpreter stack when the bytecode compiler can determine that it's safe. This change broke some checks in C API extensions that relied on `Py_REFCNT()` of `1` to determine if it's safe to modify an object in-place. Objects may have a reference count of one, but still be referenced further up the interpreter stack due to borrowing of references. This provides a replacement function for those checks. `PyUnstable_Object_IsUniqueReferencedTemporary` is more conservative: it checks that the object has a reference count of one and that it exists as a unique strong reference in the interpreter's stack of temporary variables in the top most frame.
