After updating the codebase, there are still some functions left we depend on which are now private after #106320. Would it make sense to export these again? That would make adopting `3.13` a bit easier. /CC @vstinner\r\n\r\n- `_PyBytes_Join` defined in `pycore_bytesobject.h`\r\n- `_PyObject_CallMethodIdObjArgs` defined in `pycore_call.h`\r\n- `_PyType_CalculateMetaclass` defined in `pycore_object.h`\r\n- `_PyUnicode_EQ` defined in `pycore_unicodeobject.h`\r\n- `_PyUnicode_FastCopyCharacters` defined in `pycore_unicodeobject.h` (this could be replaced with `PyUnicode_CopyCharacters` but it's used in a simplified copy of `_PyUnicode_JoinArray` which also uses `_PyUnicode_FastCopyCharacters`).\r\n\r\nOther functions include these two. However, as they are inlined, it isn't a problem to include them.\r\n- `_PyObject_CallMethodIdNoArgs` and `_PyObject_CallMethodIdOneArg` defined in `pycore_call.h`\r\n\r\n_It would be fine to keep all of them in `internal/pycore_*` and just add `PyAPI_FUNC`._\r\n\r\n/CC @hauntsaninja\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-122094\n* gh-122266\n* gh-122267\n* gh-122287\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/cdce8p","@type":"Person","name":"cdce8p"},"datePublished":"2024-07-08T12:20:34.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":12},"url":"https://github.com/121489/cpython/issues/121489"}
