[Python-Dev] Re: Behavior of `asyncio.gather` when one of submitted tasks raises a `KeyboardInterrupt`.
Sorry for my imprecision, can you read the changes about the results:
--
With one coroutine in `asyncio.gather([sub_task()])`, result is:
main_task(), be: CancelledError()
__main__
With two coroutines `asyncio.gather([sub_task(), asyncio.sleep(0)])` , result
is:
main_task(), be: KeyboardInterrupt()
__main__

[Python-Dev] Re: Behavior of `asyncio.gather` when one of submitted tasks raises a `KeyboardInterrupt`.
Thank you for the straightforward explanation. May I ask you another question?
I don't understand the behavior of this waiting primitive. So here is the case
below:
```py
import asyncio
e = KeyboardInterrupt # or SystemExit
async def sub_task():
raise e
async def main_task():
try:
await asyncio.gather(
# -- aws --
sub_task(),
asyncio.sleep(0)
)
except Exception as e:
print('\tmain_task(), e:', repr(e))
raise
except BaseException as e:
print('\tmain_task(), be:', repr(e))
if __name__ == '__main__':
try:
asyncio.run(main_task())
except e:
print(f'__main__ {e}')
```
When one coroutine `[sub_task()]`, result is:
main_task(), be: CancelledError()
__main__
When two coroutines `[sub_task(), sleep(0)]` , result is:
main_task(), be: KeyboardInterrupt()
__main__
Why are results so different when `aws` contains single coroutine or two
coroutines ?
Thank for your time

[Python-Dev] Behavior of `asyncio.gather` when one of submitted tasks raises a `KeyboardInterrupt`.
Hi, regarding this [issue93122](https://github.com/python/cpython/issues/93122), I am wondering what is the normal behavior of `asyncio.gather` when one of the submitted tasks raises a `KeyboardInterrupt` exception ? -- regardless of the value of the `return_exception` parameter. It seems that this primitive does not behave the same way with `KeyboardInterrupt` and `ZeroDivisionError` exceptions. But may be it is normal ? I have searched in the documentation [here](https://docs.python.org/3/library/asyncio-task.html#asyncio.gather) but I did not find anything. Thanks for your help.

[Python-Dev] build cpython on M1 Pro mac
Hi, I built cpython on a mac OSX 12.01. Python runs well. When starts, Python shows that version info which looks good: 'Python 3.11.0a5+ (heads/fix-issue-43352:f899da7fe5, Feb 25 2022, 10:04:53) [Clang 13.0.0 (clang-1300.0.29.30)] on darwin' But when I want to used it in VSCode to debug a script, I have the following message: --- This version of python seems to be incorrectly compiled (internal generated filenames are not absolute). This may make the debugger miss breakpoints. Related bug: http://bugs.python.org/issue1666807 --- What do I miss ? I looked for a specific option in ./configure but seen nothing ? Can someone help me please ?
