Copying some of the design discussion from the PR here (https://github.com/python/cpython/pull/22196/files#r486730457), because it belongs into the ticket. Yury Selivanov proposed to add a new C-API function for this (naming changes by me): typedef enum {PYGEN_RETURN, PYGEN_ERROR, PYGEN_NEXT} PyGenSendStatus; PyGenSendStatus PyGen_Send(PyGenObject *gen, PyObject *arg, PyObject **result); Mark Shannon and I agreed that the status code should be the return value, with some confusion whether "PyGen_" or "PyCoro_" would be appropriate prefixes. Mark Shannon wrote: I don't think [the C-API function] should be public, as a possible further improvement is to stop passing exceptions through a side channel, but in result. Maybe we don't want to do that, but lets' not add to the (already rather large) C-API. However, I think this will be demanded and used by extensions, including Cython implemented ones, so it seems better to make them use a public function than a private one. Let's continue these lines of discussion here. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41756> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
