From 1553f5e76c72243f61b454412b651706a869388f Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Tue, 1 Mar 2022 10:33:50 +0100 Subject: [PATCH] remote: read symbolic refs via `refs_read_symbolic_ref()` We have two cases in the remote code where we check whether a reference is symbolic or not, but don't mind in case it doesn't exist or in case it exists but is a non-symbolic reference. Convert these two callsites to use the new `refs_read_symbolic_ref()` function, whose intent is to implement exactly that usecase. No change in behaviour is expected from this change.
