From 97e61e0f9cd96f403504ec97cfdf38f238777560 Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Fri, 5 Aug 2022 17:58:37 +0000 Subject: [PATCH] refs: use ref_namespaces for replace refs base The git_replace_ref_base global is used to store the value of the GIT_REPLACE_REF_BASE environment variable or the default of "refs/replace/". This is initialized within setup_git_env(). The ref_namespaces array is a new centralized location for information such as the ref namespace used for replace refs. Instead of having this namespace stored in two places, use the ref_namespaces array instead. For simplicity, create a local git_replace_ref_base variable wherever the global was previously used.
