This turned out to be an effect of the setting to make the tty RAW, which Mattias and I did as part of #68559. (defconst python-shell-setup-code "\ try: import tty except ImportError: pass else: tty.setraw(0)" "Code used to setup the inferior Python processes.") This is to disable echo back on MacOS, so there is a workaround to limit this setting to MacOS only. That would not solve the `comint-interrupt-subjob' problem on MacOS, though. `comint-ptyp' is passed as the CURRENT-GROUP argument of `interrupt-process' function. It is finally processed by the process_send_signal function in process.c. If CURRENT-GROUP is non-nil, it first try to send the control character instead of sending the signal. However, I believe the control character is ignored because tty is set to RAW by the above code. I feel it would be better for process_send_signal to check if the tty is RAW, but I am not sure if that is appropriate. Since process_send_signal checks whether control characters such as VINTR are valid, we can also avoid this problem by disabling VINTR as follows. (defconst python-shell-setup-code "\ try: import tty import termios except ImportError: pass else: tty.setraw(0) attr = termios.tcgetattr(0) attr[-1][termios.VINTR] = b'\x00' termios.tcsetattr(0, termios.TCSANOW, attr)" "Code used to setup the inferior Python processes.") In summary, there are at least four possible options. 1. Set `comint-ptyp' to nil. 2. Improve process_send_signal to check if tty is RAW. 3. Disable VINTR in addition to making the tty RAW. 4. Do not set tty to RAW except on MacOS. If we choose 4, I believe MacOS requires one of 1-3.

For example, when `comint-ptyp' is t, the foreground process is interrupted instead of Python as follows. >>> import pty >>> pty.spawn("/bin/bash") $ sleep 10 sleep 10 C-c C-c^C $ However, when `comint-ptyp' is nil, the Python process is interrupted. >>> import pty >>> pty.spawn("/bin/bash") $ sleep 10 sleep 10 C-c C-cTraceback (most recent call last): File "", line 1, in File "/usr/lib/python3.12/pty.py", line 205, in spawn _copy(master_fd, master_read, stdin_read) File "/usr/lib/python3.12/pty.py", line 133, in _copy _copy(master_fd, master_read=master_read, stdin_read=stdin_read) File "/usr/lib/python3.12/pty.py", line 155, in _copy rfds, wfds, _xfds = select(rfds, wfds, []) ^^^^^^^^^^^^^^^^^^^^^^ KeyboardInterrupt >>> So I think the interrupt should work whether `comint-ptyp' is t or nil. > > 2.

Another option is to disable echo back only instead of making the tty raw. As I mentioned in my earlier mail, `python-shell-setup-code' is for disabling echo back in MacOS. Echo back must be disabled for completion to work, but it is not necessary to make the tty raw. The attached patch is to disable echo back only. Python on Windows is not affected by this patch because there is no termios module. Mattias, could you try this patch on MacOS and confirm that completion works and that ERTs pass? --Multipart_Thu_Mar_20_20:43:23_2025-1 Content-Type: application/octet-stream; type=patch; name="0001-Disable-echo-back-instead-of-setting-tty-to-raw-in-I.patch" Content-Disposition: attachment; filename="0001-Disable-echo-back-instead-of-setting-tty-to-raw-in-I.patch" Content-Transfer-Encoding: 7bit >From 53845a94e233ccc08764fe1e1c65beae61c0ffcd Mon Sep 17 00:00:00 2001 From: kobarity Date: Thu, 20 Mar 2025 19:03:33 +0900 Subject: [PATCH] Disable echo back instead of setting tty to raw in Inferior Python * lisp/progmodes/python.el (python-shell-setup-code): Change the Python setup code.
