New submission from Martin Panter:
While trying to port the example at
<https://docs.python.org/3.5/library/asyncio-task.html#example-future-with-run-until-complete>
to use “async def”, I discovered the ensure_future() function does not like
the coroutine field name changes introduced in Issue 24400:
>>> asyncio.ensure_future(slow_operation(future))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/proj/python/cpython/Lib/asyncio/futures.py", line 196, in __repr__
info = self._repr_info()
File "/home/proj/python/cpython/Lib/asyncio/tasks.py", line 105, in _repr_info
coro = coroutines._format_coroutine(self._coro)
File "/home/proj/python/cpython/Lib/asyncio/coroutines.py", line 242, in
_format_coroutine
filename = coro.gi_code.co_filename
AttributeError: 'coroutine' object has no attribute 'gi_code'
I understand the gi_ names all changed to cr_, so I guess this code has to
adjust as well.
