| | | | | | | Switch more _Py_IsImmortal(...) assertions to _Py_IsImmortalLoose(...) The remaining calls to _Py_IsImmortal are in free-threaded-only code, initialization of core objects, tests, and guards that fall back to code that works with mortal objects.

* gh-123271: Make builtin zip method safe under free-threading (#123272)Pieter Eendebak2024-08-271-1/+2
| | | | | | | | | | | | | | | | The `zip_next` function uses a common optimization technique for methods that generate tuples. The iterator maintains an internal reference to the returned tuple. When the method is called again, it checks if the internal tuple's reference count is 1. If so, the tuple can be reused. However, this approach is not safe under the free-threading build: after checking the reference count, another thread may perform the same check and also reuse the tuple. This can result in a double decref on the items of the replaced tuple and a double incref (memory leak) on the items of the tuple being set. This adds a function, `_PyObject_IsUniquelyReferenced` that encapsulates the stricter logic necessary for the free-threaded build: the internal tuple must be owned by the current thread, have a local refcount of one, and a shared refcount of zero.

* gh-117376: Make `Py_DECREF` a macro in ceval.c in free-threaded build (#122975)Sam Gross2024-08-231-15/+44
| | | | | | | | | | | `Py_DECREF` and `PyStackRef_CLOSE` are now implemented as macros in the free-threaded build in ceval.c. There are two motivations; * MSVC has problems inlining functions in ceval.c in the PGO build. * We will want to mark escaping calls in order to spill the stack pointer in ceval.c and we will want to do this around `_Py_Dealloc` (or `_Py_MergeZeroLocalRefcount` or `_Py_DecRefShared`), not around the entire `Py_DECREF` or `PyStackRef_CLOSE` call.
