Some time ago, t_e_i() only supported prefix matching. diff-tree supported recursive and non-recursive mode but it did not make any difference to prefix matching. Later on, t_e_i() gained limited recursion support to unify a similar matching code used by git-grep. It introduced two new fields in struct pathspec: max_depth and recursive. "recursive" field functions as a feature switch so that this feature is off by default. Some time after that, t_e_i() further gained wildcard support. With wildcard matching, recursive and non-recursive diff-tree mattered. "recursive" field was reused to distinguish recursion in diff-tree. This choice has a side effect that by default wildcard matching is in non-recursive mode, which is not true. All current call sites except "diff-tree without -r" (grep, traverse_commit_list, tree-walk and general tree diff) prefer recursive mode. This patch decouples the use of recursive field. The max_depth feature switch is now controlled by max_depth_valid field. diff-tree recursion is controlled by nonrecursive_diff_tree, which makes it recursive by default. Signed-off-by: Nguy=E1=BB=85n Th=C3=A1i Ng=E1=BB=8Dc Duy --- Junio, log/diff family takes wildcards just fine (even before this patch, just less reliable). If it's not mentioned in release notes before, perhaps it's worth a line in 1.7.9 annoucement. builtin/grep.c | 2 +- cache.h | 3 ++- dir.c | 4 ++-- t/t4010-diff-pathspec.sh | 8 ++++++++ tree-diff.c | 3 +-- tree-walk.c | 8 ++++---- 6 files changed, 18 insertions(+), 10 deletions(-) diff --git a/builtin/grep.c b/builtin/grep.c index 9ce064a..c081bf4 100644 --- a/builtin/grep.c +++ b/builtin/grep.c @@ -1051,7 +1051,7 @@ int cmd_grep(int argc, const char **argv, const c= har *prefix) paths =3D get_pathspec(prefix, argv + i); init_pathspec(&pathspec, paths); pathspec.max_depth =3D opt.max_depth; - pathspec.recursive =3D 1; + pathspec.max_depth_valid =3D 1; =20 if (show_in_pager && (cached || list.nr)) die(_("--open-files-in-pager only works on the worktree")); diff --git a/cache.h b/cache.h index 10afd71..f58e05a 100644 --- a/cache.h +++ b/cache.h @@ -526,7 +526,8 @@ struct pathspec { const char **raw; /* get_pathspec() result, not freed by free_pathspe= c() */ int nr; unsigned int has_wildcard:1; - unsigned int recursive:1; + unsigned int max_depth_valid:1; + unsigned int nonrecursive_diff_tree:1; int max_depth; struct pathspec_item { const char *match; diff --git a/dir.c b/dir.c index 0a78d00..5af3567 100644 --- a/dir.c +++ b/dir.c @@ -258,7 +258,7 @@ int match_pathspec_depth(const struct pathspec *ps, int i, retval =3D 0; =20 if (!ps->nr) { - if (!ps->recursive || ps->max_depth =3D=3D -1) + if (!ps->max_depth_valid || ps->max_depth =3D=3D -1) return MATCHED_RECURSIVELY; =20 if (within_depth(name, namelen, 0, ps->max_depth)) @@ -275,7 +275,7 @@ int match_pathspec_depth(const struct pathspec *ps, if (seen && seen[i] =3D=3D MATCHED_EXACTLY) continue; how =3D match_pathspec_item(ps->items+i, prefix, name, namelen); - if (ps->recursive && ps->max_depth !=3D -1 && + if (ps->max_depth_valid && ps->max_depth !=3D -1 && how && how !=3D MATCHED_FNMATCH) { int len =3D ps->items[i].len; if (name[len] =3D=3D '/') diff --git a/t/t4010-diff-pathspec.sh b/t/t4010-diff-pathspec.sh index fbc8cd8..af5134b 100755 --- a/t/t4010-diff-pathspec.sh +++ b/t/t4010-diff-pathspec.sh @@ -48,6 +48,14 @@ test_expect_success \ compare_diff_raw current expected' =20 cat >expected <<\EOF +:100644 100644 766498d93a4b06057a8e49d23f4068f1170ff38f 0a41e115ab61be= 0328a19b29f18cdcb49338d516 M path1/file1 +EOF +test_expect_success \ + '"*file1" should show path1/file1' \ + 'git diff-index --cached $tree -- "*file1" >current && + compare_diff_raw current expected' + +cat >expected <<\EOF :100644 100644 766498d93a4b06057a8e49d23f4068f1170ff38f 0a41e115ab61be= 0328a19b29f18cdcb49338d516 M file0 EOF test_expect_success \ diff --git a/tree-diff.c b/tree-diff.c index 28ad6db..164693f 100644 --- a/tree-diff.c +++ b/tree-diff.c @@ -137,8 +137,7 @@ int diff_tree(struct tree_desc *t1, struct tree_des= c *t2, enum interesting t2_match =3D entry_not_interesting; =20 /* Enable recursion indefinitely */ - opt->pathspec.recursive =3D DIFF_OPT_TST(opt, RECURSIVE); - opt->pathspec.max_depth =3D -1; + opt->pathspec.nonrecursive_diff_tree =3D !DIFF_OPT_TST(opt, RECURSIVE= ); =20 strbuf_init(&base, PATH_MAX); strbuf_add(&base, base_str, baselen); diff --git a/tree-walk.c b/tree-walk.c index f82dba6..04f1b81 100644 --- a/tree-walk.c +++ b/tree-walk.c @@ -588,7 +588,7 @@ enum interesting tree_entry_interesting(const struc= t name_entry *entry, entry_not_interesting : all_entries_not_interesting; =20 if (!ps->nr) { - if (!ps->recursive || ps->max_depth =3D=3D -1) + if (!ps->max_depth_valid || ps->max_depth =3D=3D -1) return all_entries_interesting; return within_depth(base->buf + base_offset, baselen, !!S_ISDIR(entry->mode), @@ -609,7 +609,7 @@ enum interesting tree_entry_interesting(const struc= t name_entry *entry, if (!match_dir_prefix(base_str, match, matchlen)) goto match_wildcards; =20 - if (!ps->recursive || ps->max_depth =3D=3D -1) + if (!ps->max_depth_valid || ps->max_depth =3D=3D -1) return all_entries_interesting; =20 return within_depth(base_str + matchlen + 1, @@ -634,7 +634,7 @@ enum interesting tree_entry_interesting(const struc= t name_entry *entry, * Match all directories.
