Subject: [PATCH v4 15/16] refs.c: remove fallback-to-main-store code get_submodule_ref_store()
Date: Wed, 23 Aug 2017 19:37:03 +0700 [thread overview]
Message-ID: <20170823123704.16518-16-pclouds@gmail.com> (raw)
In-Reply-To: <20170823123704.16518-1-pclouds@gmail.com>
At this state, there are three get_submodule_ref_store() callers:
- for_each_remote_ref_submodule()
- handle_revision_pseudo_opt()
- resolve_gitlink_ref()
The first two deal explicitly with submodules (and we should never fall
back to the main ref store as a result). They are only called from
submodule.c:
- find_first_merges()
- submodule_needs_pushing()
- push_submodule()
The last one, as its name implies, deals only with submodules too, and
the "submodule" (path) argument must be a non-NULL, non-empty string.
So, this "if NULL or empty string" code block should never ever
trigger. And it's wrong to fall back to the main ref store
anyway. Delete it.
