From 76887df01440018e1e757761fea81a4d3a676f25 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Sat, 16 Oct 2021 11:39:14 +0200 Subject: refs API: remove refs_read_ref_full() wrapper MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Remove the refs_read_ref_full() wrapper in favor of migrating various refs.c API users to the underlying refs_werrres_ref_unsafe() function. A careful reading of these callers shows that the callers of this function did not care about "errno", by moving away from the refs_resolve_ref_unsafe() wrapper we can be sure that nothing relies on it anymore.
