Subject: [PATCH 6/7] submodule: remove add_submodule_odb
Date: Tue, 29 Sep 2020 16:53:49 +0100 [thread overview]
Message-ID: <20200929155350.49066-7-andrew@adoakley.name> (raw)
In-Reply-To: <20200929155350.49066-1-andrew@adoakley.name>
The remaining callers to get_submodule_ref_store do not require access
to the objects, and do not call add_submodule_odb. This function can
therefore be removed and the refstore marked as not having access to the
objects.
The submodule ref-store tests have been updated to reflect the fact that
the objects are no longer available in the ref-store.

- * Submodules
- * ----------
- *
- * If you want to iterate the refs of a submodule you first need to add the
- * submodules object database. You can do this by a code-snippet like
- * this:
- *
- * const char *path = "path/to/submodule"
- * if (add_submodule_odb(path))
- * die("Error submodule '%s' not populated.", path);
- *
- * `add_submodule_odb()` will return zero on success. If you
- * do not do this you will get an error for each ref that it does not point
- * to a valid object.
- *
- * Note: As a side-effect of this you cannot safely assume that all
- * objects you lookup are available in superproject. All submodule objects
- * will be available the same way as the superprojects objects.
- *
- * Example:
- * --------
- *
- * ----
- * static int handle_remote_ref(const char *refname,
- * const unsigned char *sha1, int flags, void *cb_data)
- * {
- * struct strbuf *output = cb_data;
- * strbuf_addf(output, "%s\n", refname);
- * return 0;
- * }
- *
