Stefan Behnel added the comment: I found one more place in asyncio.coroutines, around line 190 in the coroutine() decorator:
if inspect.isgeneratorfunction(func): coro = func else: @functools.wraps(func) def coro(*args, **kw): res = func(*args, **kw) if isinstance(res, futures.Future) or inspect.isgenerator(res): res = yield from res return res The wrapped isgenerator() check should be replaced by an Awaitable ABC check, e.g. this works for me: """ res = func(*args, **kw) if isinstance(res, futures.Future) or inspect.isgenerator(res): res = yield from res + else: + await_res = getattr(res, '__await__', None) + if await_res is not None: + res = yield from await_res() return res """ ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24004> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
