From 3284b93862b0aaea9d8e708f0aabd53e3e94409e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Tue, 8 Aug 2023 22:05:57 +0200 Subject: parse-options: disallow negating OPTION_SET_INT 0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit An option of type OPTION_SET_INT can be defined to set its variable to zero. It's negated variant will do the same, though, which is confusing. Several such options were fixed by disabling negation, changing the value to set or using a different option type: 991c552916 (ls-tree: fix --no-full-name, 2023-07-18) e12cb98e1e (branch: reject "--no-all" and "--no-remotes" early, 2023-07-18) 68cbb20e73 (show-branch: reject --[no-](topo|date)-order, 2023-07-19) 3821eb6c3d (reset: reject --no-(mixed|soft|hard|merge|keep) option, 2023-07-19) 36f76d2a25 (pack-objects: fix --no-quiet, 2023-07-21) 3a5f308741 (pack-objects: fix --no-keep-true-parents, 2023-07-21) c95ae3ff9c (describe: fix --no-exact-match, 2023-07-21) d089a06421 (bundle: use OPT_PASSTHRU_ARGV, 2023-07-29) Check for such options that allow negation in parse_options_check() and report them to find future cases quicker.
