From 4f38f6b5bafb1f7f85c7b54d0bb0a0e977cd947c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Thu, 28 Aug 2008 20:02:12 +0700 Subject: diff*: fix worktree setup MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This fixes "git diff", "git diff-files" and "git diff-index" to work correctly under worktree setup. Because diff* family works in many modes and not all of them require worktree, Junio made a nice summary (with a little modification from me): * diff-files is about comparing with work tree, so it obviously needs a work tree; * diff-index also does, except "diff-index --cached" or "diff --cached TREE" * no-index is about random files outside git context, so it obviously doesn't need any work tree; * comparing two (or more) trees doesn't; * comparing two blobs doesn't; * comparing a blob with a random file doesn't; Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano diff --git a/builtin-diff-index.c b/builtin-diff-index.c index 17d851b..0483749 100644 --- a/builtin-diff-index.c +++ b/builtin-diff-index.c @@ -39,6 +39,8 @@ int cmd_diff_index(int argc, const char **argv, const char *prefix) if (rev.pending.nr != 1 || rev.max_count != -1 || rev.min_age != -1 || rev.max_age != -1) usage(diff_cache_usage); + if (!cached) + setup_work_tree(); if (read_cache() < 0) { perror("read_cache"); return -1; diff --git a/builtin-diff.c b/builtin-diff.c index 7ffea97..037c303 100644 --- a/builtin-diff.c +++ b/builtin-diff.c @@ -122,6 +122,8 @@ static int builtin_diff_index(struct rev_info *revs, usage(builtin_diff_usage); argv++; argc--; } + if (!cached) + setup_work_tree(); /* * Make sure there is one revision (i.e. pending object), * and there is no revision filtering parameters. @@ -225,6 +227,7 @@ static int builtin_diff_files(struct rev_info *revs, int argc, const char **argv (revs->diffopt.output_format & DIFF_FORMAT_PATCH)) revs->combine_merges = revs->dense_combined_merges = 1; + setup_work_tree(); if (read_cache() < 0) { perror("read_cache"); return -1; diff --git a/git.c b/git.c index 37b1d76..fdb0f71 100644 --- a/git.c +++ b/git.c @@ -286,7 +286,7 @@ static void handle_internal_command(int argc, const char **argv) { "count-objects", cmd_count_objects, RUN_SETUP }, { "describe", cmd_describe, RUN_SETUP }, { "diff", cmd_diff }, - { "diff-files", cmd_diff_files, RUN_SETUP }, + { "diff-files", cmd_diff_files, RUN_SETUP | NEED_WORK_TREE }, { "diff-index", cmd_diff_index, RUN_SETUP }, { "diff-tree", cmd_diff_tree, RUN_SETUP }, { "fast-export", cmd_fast_export, RUN_SETUP }, diff --git a/t/t1501-worktree.sh b/t/t1501-worktree.sh index 2ee88d8..8244b3a 100755 --- a/t/t1501-worktree.sh +++ b/t/t1501-worktree.sh @@ -28,6 +28,7 @@ test_rev_parse() { [ $# -eq 0 ] && return } +EMPTY_TREE=$(git write-tree) mkdir -p work/sub/dir || exit 1 mv .git repo.git || exit 1 @@ -106,12 +107,66 @@ test_expect_success 'repo finds its work tree from work tree, too' ' ' test_expect_success '_gently() groks relative GIT_DIR & GIT_WORK_TREE' ' - cd repo.git/work/sub/dir && + (cd repo.git/work/sub/dir && GIT_DIR=../../..
