There are three options: (1) Status-quo (keep everything as is in 3.8b1): this breaks any Cython project which has not been recythonized with the latest Cython. For example, it is (together with bpo-37221 which is planned to be fixed) the reason that "pip install numpy" doesn't work with 3.8b1. Typically, projects run Cython at packaging time, so this needs a new source release of every single Cython-using package. (2) Apply PR 14193: the only disadvantage that I can think of is that types would get 8 bytes larger. We should stop discussing and just do this. (3) Put back tp_print the way it was in 3.7: same as (2), except that it goes against PEP 590 as putting tp_vectorcall_offset in place of tp_print was a design decision made in that PEP. It would break ABI (any static type compiled with 3.7 would break on 3.8) and it prevents Cython from backporting vectorcall to 3.7. It's also a larger change compared to 3.8b1, so it's more work and more risky. In my personal opinion, the worst of the three options. Then there is the further question whether we should apply this only on 3.8 or possibly also later versions. But here the consensus seems to be 3.8 only. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37250> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
