We say this, suggesting that repo_get_default_remote()'s signature is
just get_default_remote()'s plus a "struct repository *" (like most
repo_*). But..

repo_get_default_remote() actually take yet another argument - refname.
It looks to me that repo_get_default_remote() shouldn't take the
refname argument at all and that we should be using
refs_resolve_ref_unsafe() instead, like:
+static char *repo_get_default_remote(struct repository *repo)
{
char *dest = NULL, *ret;
struct strbuf sb = STRBUF_INIT;
- const char *refname = resolve_ref_unsafe("HEAD", 0, NULL, NULL);
+ const char *refname = refs_resolve_ref_unsafe(
+ get_main_ref_store(repo), "HEAD", 0, NULL, NULL /*, errno? */);
this makes the rest of the code a lot cleaner..
+static char *get_default_remote_submodule(const char *module_path)
+{
+ struct repository subrepo;
+
+ repo_submodule_init(&subrepo, the_repository, module_path, null_oid());
+ return repo_get_default_remote(&subrepo);
+}
+
+static char *get_default_remote(void)
+{
+ return repo_get_default_remote(the_repository);
+}
And because it's quite idiomatic to initialize the subrepo struct in
order to can call repo_* functions, we could even drop
get_default_remote_submodule() altogether.
As for why this wasn't the original approach, the only reason I can
think of is that we didn't realize get_main_ref_store(subrepo) was an
option.
