New submission from Petr Viktorin <encu...@gmail.com>:
The following PEP 573 were not added to the Windows list of stable ABI symbols (PC/python3dll.c): - PyModule_AddType - PyType_FromModuleAndSpec - PyType_GetModule - PyType_GetModuleState I'd like to add them. Also, the PEP introduces the (METH_FASTCALL | METH_KEYWORDS | METH_METHOD) calling convention, but METH_FASTCALL is not part of the stable ABI (and it other uses are not suitable for stable ABI). I propose adding a new value, METH_METHOD_ARGS_KWD (name up for bikeshedding), which would be equal to (METH_FASTCALL | METH_KEYWORDS | METH_METHOD) but part of the limited API. Does that sound like a good idea? On the sprint, Steve mentioned that it would be possible to backport this to Python 3.9.1, even though it would mean a weird minor-version requirement. I no longer think that's a good idea: fixing the stable ABI will be a longer-term project, and I don't want to fight issues in a 3.9 backport. FWIW, for the longer-term project, I started a brainstorming repo at https://github.com/encukou/abi3 (Yes, it has some overlap with Victor's more general notes at https://pythoncapi.readthedocs.io/ ) But I'd like to get the additions above in to unblock #42111 before I start on improving the stable ABI in general. ---------- components: C API messages: 379762 nosy: ncoghlan, petr.viktorin, scoder, vstinner priority: normal severity: normal status: open title: Add PEP 573 to the stable ABI versions: Python 3.10 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42171> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
