But "o" is ambiguous, between "on" and "off". I can't imagine why assuming the user wanted to type "on" is a good idea, it might have been a typo. This commit makes gdb error out. We now get: (gdb) maint test-settings set boolean o "on" or "off" expected. (gdb) maint test-settings set auto-boolean o "on", "off" or "auto" expected. gdb/ChangeLog: 2019-06-13 Pedro Alves * cli/cli-setshow.c (parse_auto_binary_operation) (parse_cli_boolean_value): Don't allow "o". gdb/testsuite/ChangeLog: 2019-06-13 Pedro Alves * gdb.base/settings.exp (test-boolean, test-auto-boolean): Check that "o" is ambiguous.
