New submission from Io Mintz <i...@mintz.cc>:
"python3 -m asyncio" swallows KeyboardInterrupt while editing a line. Problem steps: ============== - run python -m asyncio - press ^C Expected behavior (normal CPython REPL, as well as python -m code): ================================================================== The current input line is abandoned and "\nKeyboardInterrupt" is printed. Sample for "spam^C" with the normal REPL: ----------------------------------------- Python 3.8.0 (default, Oct 23 2019, 18:51:26) [GCC 9.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> spam KeyboardInterrupt Python 3.9.0a1+ (heads/master:a62ad4730c, Dec 2 2019, 17:38:37) [GCC 9.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> spam KeyboardInterrupt Sample for "spam^C" in the InteractiveConsole REPL, as invoked by `python -m code`: ----------------------------------------------------------------------------------- Python 3.8.0 (default, Oct 23 2019, 18:51:26) [GCC 9.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. (InteractiveConsole) >>> spam KeyboardInterrupt Python 3.9.0a1+ (heads/master:a62ad4730c, Dec 2 2019, 17:38:37) [GCC 9.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. (InteractiveConsole) >>> spam KeyboardInterrupt Actual behavior: ================ The KeyboardInterrupt is ignored, the current input line remains on screen, and a new line is not started: asyncio REPL 3.8.0 (default, Oct 23 2019, 18:51:26) [GCC 9.2.0] on linux Use "await" directly instead of "asyncio.run()". Type "help", "copyright", "credits" or "license" for more information. >>> import asyncio >>> spam asyncio REPL 3.9.0a1+ (heads/master:a62ad4730c, Dec 2 2019, 17:38:37) [GCC 9.2.0] on linux Use "await" directly instead of "asyncio.run()". Type "help", "copyright", "credits" or "license" for more information. >>> import asyncio >>> spam Workaround ========== If editing a continued block (ie a line prefixed by sys.ps2 / "..."), enter any invalid syntax (such as unindented code) to cancel the current block. If editing a single line, press ^U to clear the line. OS Details ========== Arch Linux, python extra/python 3.8.0-1. ---------- components: asyncio messages: 357738 nosy: asvetlov, iomintz, yselivanov priority: normal severity: normal status: open title: asyncio REPL swallows KeyboardInterrupt while editing versions: Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38958> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
