New submission from David Hilton <dhilt...@gmail.com>:
If a python piece of code imports cython code with async defs, `asyncio.iscoroutinefunction` cannot determine that the code is async. https://github.com/cython/cython/issues/2273#issuecomment-531537624 scoder is open to marking async defs so that they can be identified, just like `asyncio.coroutine`: https://github.com/python/cpython/blob/ae239f6b0626e926613a4a1dbafa323bd41fec32/Lib/asyncio/coroutines.py#L156 However, that is an internal interface and `@coroutine` is deprecated. -------------- Can we have some official way of marking functions as async that will not be deprecated? The easiest would be for `asyncio.iscoroutinefunction` to look for `_is_coroutine = True`, and promise to keep looking for that value. This would also allow for functools.partial to easily mark that it's returning an async function, which some people seem to care about. ---------- components: asyncio messages: 352812 nosy: asvetlov, dhiltonp, yselivanov priority: normal severity: normal status: open title: iscoroutinefunction broken with cython - allow tagging of functions as async? type: enhancement versions: Python 2.7, Python 3.5, Python 3.6, Python 3.7, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38225> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
