Rename resolve_ref() to resolve_ref_unsafe()
resolve_ref() may return a pointer to a shared buffer and can be overwritten by the next resolve_ref() calls. Callers need to pay attention, not to keep the pointer when the next call happens. Rename with "_unsafe" suffix to warn developers (or reviewers) before introducing new call sites. This patch is generated using the following command git grep -l 'resolve_ref(' -- '*.[ch]'|xargs sed -i 's/resolve_ref(/resolve_ref_unsafe(/g' Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
