Hi all,
I think that PEP 573 is ready to be accepted, to greatly improve the state
of extension modules in CPython 3.9.
https://www.python.org/dev/peps/pep-0573/
It has come a long way since the original proposal and went through several
iterations and discussions by various interested people, effectively
reducing its scope quite a bit. So this is the last call for comments on
the latest version of the PEP, before I will pronounce on it. Please keep
the discussion in this thread.
I have received substantial private feedback, and I'll need to make
another update to:
## Better separate C-API additions:
- PyType_FromModuleAndSpec
- PyType_GetModule
- PyType_DefiningTypeFromSlotFunc
- PyType_GetModuleState
- METH_METHOD flag
- PyCMethod (function signature)
from CPython implementation details:
- ht_module (member of the undocumented PyHeapTypeObject)
- PyCMethodObject (extends the undocumented PyCFunctionObject; used
internally to hold information to pass to PyCMethod)
- PyCFunction_GET_CLASS (helper for the internal class)
- defining_class clinic converter
(See
https://mail.python.org/archives/list/capi-...@python.org/message/B2VDVLABM4RQ4ATEJXFZYWEGTBZPUBKW/
for a proposal to formalize this distinction as "rings", and for some
reasons why it is good.)
## Clarify that ht_module is not inherited
## Specify what "defining class" means more rigorously
