Miss Islington (bot) c128718f30 [3.13] gh-121368: Fix seq lock memory ordering in _PyType_Lookup (GH-121388) (#121505 ) The `_PySeqLock_EndRead` function needs an acquire fence to ensure that the load of the sequence happens after any loads within the read side critical section. The missing fence can trigger bugs on macOS arm64. Additionally, we need a release fence in `_PySeqLock_LockWrite` to ensure that the sequence update is visible before any modifications to the cache entry. (cherry picked from commit `1d3cf79a50`) Co-authored-by: Sam Gross <colesbury@gmail.com>		2024-07-08 19:15:58 +00:00

The Python C API
================

The C API is divided into these sections:

1. ``Include/``: Limited API
2. ``Include/cpython/``: CPython implementation details
3. ``Include/cpython/``, names with the ``PyUnstable_`` prefix: API that can
   change between minor releases
4. ``Include/internal/``, and any name with ``_`` prefix: The internal API

Information on changing the C API is available `in the developer guide`_
