I close the issue. While this issue is not fully fixed, it's a milestone of my "stable ABI" goal. I prefer to address remaining issues in new separted issues. This issues is not fully fixed, there are are still a 4 macros which access directly PyTypeObject members: * PySequence_ITEM() * _PyObject_SIZE() * _PyObject_VAR_SIZE() * PyType_HasFeature() (if Py_LIMITED_API is not defined) PySequence_ITEM() and PyType_HasFeature() are important for performance, I prefer to have a PEP before changing these two functions. _PyObject_SIZE() and _PyObject_VAR_SIZE() should be made public with a better name like PyObject_SizeOf() and PyVarObject_SizeOf(). But I prefer to do that in a separated issue. IMO it would be interesting to merge the PyHeapTypeObject structure into the PyTypeObject structure: https://bugs.python.org/issue46433#msg411167 And make the PyTypeObject opaque: deprecate static types and promote the usage of heap types in C extensions. That's a big project which may be splitted into multiple issues and the final change may need its own PEP. ---------- resolution: -> fixed stage: patch review -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40170> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
