you can see the analogous sync contextmanager issue on python3.6 with: ``` import logging from contextlib import contextmanager @contextmanager def foo(): yield def test(): f = foo() f.__enter__() f.__enter__() test() ``` on python3.7+ you get the bpo-30306 behaviour ``` Traceback (most recent call last): File "sync.py", line 14, in <module> test() File "sync.py", line 12, in test f.__enter__() File "/usr/lib/python3.8/contextlib.py", line 111, in __enter__ del self.args, self.kwds, self.func AttributeError: args ``` and python3.6 you get the same sort of error you see now for asynccontextmanagers: ``` Traceback (most recent call last): File "sync.py", line 14, in <module> test() File "sync.py", line 12, in test f.__enter__() File "/usr/lib/python3.6/contextlib.py", line 83, in __enter__ raise RuntimeError("generator didn't yield") from None RuntimeError: generator didn't yield ``` ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45996> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
