tree-walk.c: make tree_entry_interesting() take an index
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@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
