New submission from Lidi Zheng <li...@google.com>:
This issue exists since 3.6. The implementation of get stack on Task is looking for two attribute [1]: "cr_frame" for coroutines, "gi_frame" for generators (legacy coroutines). However, PyAsyncGenObject provides none of them but "ag_frame" [2]. Fix PR: https://github.com/python/cpython/pull/18669 A simple reproduce: def test_async_gen_aclose_compatible_with_get_stack(self): async def async_generator(): yield object() async def run(): ag = async_generator() asyncio.create_task(ag.aclose()) tasks = asyncio.all_tasks() for task in tasks: # No AttributeError raised task.get_stack() self.loop.run_until_complete I found this in my project I want to view who created the Tasks.
