In order to support :(attr) when matching pathspec on a tree, tree_entry_interesting() needs to take an index (because git_check_attr() needs it). This is the preparation step for it. This also makes it clearer what index we fall back to when looking up attributes during an unpack-trees operation: the source index. This also fixes revs->pruning.repo initialization that should have been done in 2abf350385 (revision.c: remove implicit dependency on the_index - 2018-09-21). Without it, skip_uninteresting() will dereference a NULL pointer through this call chain get_revision(revs) get_revision_internal get_revision_1 try_to_simplify_commit rev_compare_tree diff_tree_oid(..., &revs->pruning) ll_diff_tree_oid diff_tree_paths ll_diff_tree skip_uninteresting Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@xxxxxxxxx> --- builtin/grep.c | 3 ++- builtin/merge-tree.c | 2 +- list-objects.c | 3 ++- revision.c | 1 + tree-diff.c | 3 ++- tree-walk.c | 22 ++++++++++++++-------- tree-walk.h | 10 ++++++---- tree.c | 3 ++- unpack-trees.c | 6 +++--- 9 files changed, 33 insertions(+), 20 deletions(-) diff --git a/builtin/grep.c b/builtin/grep.c index 56e4a11052..f6e086c287 100644 --- a/builtin/grep.c +++ b/builtin/grep.c @@ -568,7 +568,8 @@ static int grep_tree(struct grep_opt *opt, const struct pathspec *pathspec, if (match != all_entries_interesting) { strbuf_addstr(&name, base->buf + tn_len);
