Subject: `interrupt-process` doesn't work for Python on Windows
Date: Wed, 09 Feb 2022 10:17:33 +0100 [thread overview]

Hi,
After running into an issue with a package that enhances Emacs' inferior Python shell and a long back and forth with the package's maintainer, the maintainer feels there might be a bug in Emacs. Specifically, the command `interrupt-process` is not able to interrupt the Python process on Windows. Details are in this message and in the message's thread:
https://github.com/jdtsmith/python-mls/issues/8#issuecomment-1033120469
To quote the relevant section:
====================
Here is the issue: `interrupt-process` (and internal C function) does not function correctly to interrupt Python on Windows emacs! While at the command prompt, a simple `C-c` does correctly interrupt (and returns `Keyboard Interrupt\n>>> ` promptly), `interrupt-process` does not, and leads to the double-traceback you reported earlier, but _only after you send another newline_. This is incorrect behavior, and seems to represent a bug in the way Emacs sends interrupts on Windows, which differs from `C-c` in the command prompt.
It's easy to verify the difference:
* `C-c` at `>>> ` python prompt in "Command Prompt": immediate `KeyboardInterrupt` and prompt.
* `C-c C-c` at `>>> ` python prompt in Emacs _Python_: no `KeyboardInterrupt`.
====================
Should I file a bug report about this? Or is this something Emacs can do nothing about?
TIA
Joost
