From 8102d10ff8317c1e0ba5afb3a41b6a2bc523ff97 Mon Sep 17 00:00:00 2001 From: Bence Ferdinandy Date: Fri, 22 Nov 2024 13:28:44 +0100 Subject: refs: standardize output of refs_read_symbolic_ref When the symbolic reference we want to read with refs_read_symbolic_ref is actually not a symbolic reference, the files and the reftable backends return different values (1 and -1 respectively). Standardize the returned values so that 0 is success, -1 is a generic error and -2 is that the reference was actually non-symbolic.
