From 9b67eb6fbeb9666640f34cccf401cfea22f7bd22 Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Thu, 17 Nov 2022 06:46:43 +0100 Subject: refs: get rid of global list of hidden refs We're about to add a new argument to git-rev-list(1) that allows it to add all references that are visible when taking `transfer.hideRefs` et al into account. This will require us to potentially parse multiple sets of hidden refs, which is not easily possible right now as there is only a single, global instance of the list of parsed hidden refs. Refactor `parse_hide_refs_config()` and `ref_is_hidden()` so that both take the list of hidden references as input and adjust callers to keep a local list, instead. This allows us to easily use multiple hidden-ref lists. Furthermore, it allows us to properly free this list before we exit.
