New submission from hai shi <shihai1...@126.com>:
Copied from https://bugs.python.org/issue40512#msg399847: Victor: PyStructSequence_InitType2() is not compatible with subinterpreters: it uses static types. Moreover, it allocates tp_members memory which is not released when the type is destroyed. But I'm not sure that the type is ever destroyed, since this API is designed for static types. > PyStructSequence_InitType2() is not compatible with subinterpreters: it uses > static types.

IMO, I suggest to create a new function, PyStructSequence_FromModuleAndDesc(module, desc, flags) to create a heaptype and don't aloocates memory block for tp_members,something like 'PyType_FromModuleAndSpec()`. ---------- components: C API messages: 401129 nosy: petr.viktorin, shihai1991, vstinner priority: normal severity: normal status: open title: [subinterpreters][C API] Add a new function to create PyStructSequence from Heap. versions: Python 3.11 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45113> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
