asyncio.print_call_graph() includes its own frame in the call stack #156327
Description
Bug report
Bug description:
Currently asyncio-graph.rst shows the example of print_call_graph() usage:
import asyncio
async def test():
asyncio.print_call_graph()
async def main():
async with asyncio.TaskGroup() as g:
g.create_task(test(), name='test')
asyncio.run(main())with output:
* Task(name='test', id=0x1039f0fe0)
+ Call stack:
| File 't2.py', line 4, in async test()
+ Awaited by:
* Task(name='Task-1', id=0x103a5e060)
+ Call stack:
| File 'taskgroups.py', line 107, in async TaskGroup.__aexit__()
| File 't2.py', line 7, in async main()
But actually it mentions print_call_graph() in the graph which is not correct
* Task(name='test', id=0x103d349b0)
+ Call stack:
| File '/Users/timofeiivankov/cpython/Lib/asyncio/graph.py', line 276, in print_call_graph()
| File '/Users/timofeiivankov/cpython/repro.py', line 4, in async test()
+ Awaited by:
* Task(name='Task-1', id=0x103d34b90)
+ Call stack:
| File '/Users/timofeiivankov/cpython/Lib/asyncio/taskgroups.py', line 125, in async TaskGroup._aexit()
| File '/Users/timofeiivankov/cpython/Lib/asyncio/taskgroups.py', line 75, in async TaskGroup.__aexit__()
| File '/Users/timofeiivankov/cpython/repro.py', line 7, in async main()
Proposed fix is to increment the depth in print_call_graph():
def print_call_graph(
future: futures.Future | None = None,
/,
*,
file: io.Writer[str] | None = None,
depth: int = 1,
limit: int | None = None,
) -> None:
"""Print the async call graph for the current task or the provided Future."""
print(format_call_graph(future, depth=depth + 1, limit=limit), file=file)I have a fix ready for that
