New submission from Florian Bruhin <python....@the-compiler.org>:
A minor issue I just discovered today: When e.g. doing "python3 --foo", the output is: unknown option --foo unknown option --foo unknown option --foo usage: /usr/bin/python3 [option] ... [-c cmd | -m mod | file | -] [arg] ... With more dashes in the options, it seems to get worse: unknown option --foo-bar-baz unknown option --foo-bar-baz unknown option --foo-bar-baz unknown option --foo-bar-baz unknown option --foo-bar-baz unknown option --foo-bar-baz unknown option --foo-bar-baz usage: /usr/bin/python3 [option] ... [-c cmd | -m mod | file | -] [arg] ... This seems very similar to issue16306 (thus why I added people involved there to the nosy list), except that it happens with long rather than short arguments. This only happens with Python 3.8/3.9, not 3.7 or older. I was able to bisect this to the following commit: commit 6dcb54228e7520abd058897440c26e323f62afcd Author: Victor Stinner <vstin...@redhat.com> Date: Tue Mar 5 02:44:12 2019 +0100 bpo-36142: Add _PyPreConfig_ReadFromArgv() (GH-12173) The new function is now responsible to parse -E and -I command line arguments. ---------- components: Interpreter Core messages: 368231 nosy: The Compiler, hieu.nguyen, serhiy.storchaka, tweksteen, vstinner priority: normal severity: normal status: open title: Multiple "unknown option" errors when passing unknown arguments to the interpreter type: behavior versions: Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40527> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
