From 485fd2c3dae9c05b43fe237f402274a59eb68e81 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Tue, 28 Dec 2021 14:28:46 +0100 Subject: [PATCH] cat-file: make --batch-all-objects a CMDMODE MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The usage of OPT_CMDMODE() in "cat-file"[1] was added in parallel with the development of[3] the --batch-all-objects option[4], so we've since grown[5] checks that it can't be combined with other command modes, when it should just be made a top-level command-mode instead. It doesn't combine with --filters, --textconv etc. By giving parse_options() information about what options are mutually exclusive with one another we can get the die() message being removed here for free, we didn't even use that removed message in some cases, e.g. for both of: --batch-all-objects --textconv --batch-all-objects --filters We'd take the "goto usage" in the "if (opt)" branch, and never reach the previous message. Now we'll emit e.g.: $ git cat-file --batch-all-objects --filters error: option `filters' is incompatible with --batch-all-objects 1. b48158ac94c (cat-file: make the options mutually exclusive, 2015-05-03) 2. https://lore.kernel.org/git/xmqqtwspgusf.fsf@gitster.dls.corp.google.com/ 3. https://lore.kernel.org/git/20150622104559.GG14475@peff.net/ 4. 6a951937ae1 (cat-file: add --batch-all-objects option, 2015-06-22) 5. 321459439e1 (cat-file: support --textconv/--filters in batch mode, 2016-09-09) Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano --- builtin/cat-file.c | 25 +++++++++++-------------- t/t1006-cat-file.sh | 7 ++----- 2 files changed, 13 insertions(+), 19 deletions(-) diff --git a/builtin/cat-file.c b/builtin/cat-file.c index 6d0f645301..8735620813 100644 --- a/builtin/cat-file.c +++ b/builtin/cat-file.c @@ -674,6 +674,8 @@ int cmd_cat_file(int argc, const char **argv, const char *prefix) N_("for blob objects, run textconv on object's content"), 'c'), OPT_CMDMODE(0, "filters", &opt, N_("for blob objects, run filters on object's content"), 'w'), + OPT_CMDMODE(0, "batch-all-objects", &opt, + N_("show all objects with --batch or --batch-check"), 'b'), OPT_STRING(0, "path", &force_path, N_("blob"), N_("use a specific path for --textconv/--filters")), OPT_BOOL(0, "allow-unknown-type", &unknown_type, @@ -689,8 +691,6 @@ int cmd_cat_file(int argc, const char **argv, const char *prefix) batch_option_callback), OPT_BOOL(0, "follow-symlinks", &batch.follow_symlinks, N_("follow in-tree symlinks (used with --batch or --batch-check)")), - OPT_BOOL(0, "batch-all-objects", &batch.all_objects, - N_("show all objects with --batch or --batch-check")), OPT_BOOL(0, "unordered", &batch.unordered, N_("do not order --batch-all-objects output")), OPT_END() @@ -699,30 +699,27 @@ int cmd_cat_file(int argc, const char **argv, const char *prefix) git_config(git_cat_file_config, NULL); batch.buffer_output = -1; - argc = parse_options(argc, argv, prefix, options, usage, 0); - if (opt) { + argc = parse_options(argc, argv, prefix, options, usage, 0); + if (argc && batch.enabled) + usage_with_options(usage, options); + if (opt == 'b') { + batch.all_objects = 1; + } else if (opt) { if (batch.enabled && (opt == 'c' || opt == 'w')) batch.cmdmode = opt; else if (argc == 1) obj_name = argv[0]; else usage_with_options(usage, options); - } - if (!opt && !batch.enabled) { + } else if (!opt && !batch.enabled) { if (argc == 2) { exp_type = argv[0]; obj_name = argv[1]; } else usage_with_options(usage, options); - } - if (batch.enabled) { - if (batch.cmdmode != opt || argc) - usage_with_options(usage, options); - if (batch.cmdmode && batch.all_objects) - die("--batch-all-objects cannot be combined with " - "--textconv nor with --filters"); - } + } else if (batch.enabled && batch.cmdmode != opt) + usage_with_options(usage, options); if ((batch.follow_symlinks || batch.all_objects) && !batch.enabled) { usage_with_options(usage, options); diff --git a/t/t1006-cat-file.sh b/t/t1006-cat-file.sh index fc9191c1b9..ebec2061d2 100755 --- a/t/t1006-cat-file.sh +++ b/t/t1006-cat-file.sh @@ -14,7 +14,8 @@ for switches in \ '-p -t' \ '-t -s' \ '-s --textconv' \ - '--textconv --filters' + '--textconv --filters' \ + '--batch-all-objects -e' do test_expect_success "usage: cmdmode $switches" ' test_cmdmode_usage git cat-file $switches @@ -41,10 +42,6 @@ do test_expect_success "usage: $opt requires another option" ' test_expect_code 129 git cat-file $opt ' - - test_expect_failure "usage: incompatible options: --batch-all-objects with $opt" ' - test_incompatible_usage git cat-file --batch-all-objects $opt - ' done for opt in $short_modes
