As can easily be seen from grepping in our sources, we had these uses of "the_repository" in various library code in cases where the function in question was already getting a "struct repository *" argument. Let's use that argument instead. Out of these changes only the changes to "cache-tree.c", "commit-reach.c", "shallow.c" and "upload-pack.c" would have cleanly applied before the migration away from the "repo_*()" wrapper macros in the preceding commits. The rest aren't new, as we'd previously implicitly refer to "the_repository", but it's now more obvious that we were doing the wrong thing all along, and should have used the parameter instead. The change to change "get_index_format_default(the_repository)" in "read-cache.c" to use the "r" variable instead should arguably have been part of [1], or in the subsequent cleanup in [2]. Let's do it here, as can be seen from the initial code in [3] it's not important that we use "the_repository" there, but would prefer to always use the current repository. This change excludes the "the_repository" use in "upload-pack.c"'s upload_pack_advertise(), as the in-flight [4] makes that change. 1. ee1f0c242ef (read-cache: add index.skipHash config option, 2023-01-06) 2. 6269f8eaad0 (treewide: always have a valid "index_state.repo" member, 2023-01-17) 3. 7211b9e7534 (repo-settings: consolidate some config settings, 2019-08-13) 4. <Y/hbUsGPVNAxTdmS@coredump.intra.peff.net> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
