New submission from Florian Bruhin <python....@the-compiler.org>:
When shutil.get_terminal_size() is used in a PTY, the os.get_terminal_size() call can return (0, 0). With the pty script from https://github.com/python/mypy/issues/8144#issue-537760245: $ python3 t.py python3 -c 'import shutil; print(shutil.get_terminal_size())' os.terminal_size(columns=0, lines=0) While the following cases *are* handled by returning the fallback: - COLUMNS or lines being non-existent or 0 - os.get_terminal_size raising The case of os.get_terminal_size() succeeding but returning (0, 0) should probably be handled the same way as well. This e.g. affects mypy when run with pre-commit: https://github.com/pre-commit/mirrors-mypy/issues/29 ---------- components: Library (Lib) messages: 379773 nosy: The Compiler, giampaolo.rodola, tarek priority: normal severity: normal status: open title: shutil.get_terminal_size() returns 0 when run in a pty type: behavior versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42174> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
