Subject: [PATCH v4 5/7] object-file: only register submodule ODB if needed
Date: Fri,  8 Oct 2021 14:08:18 -0700	[thread overview]
Message-ID: <78473b0f892da8f69b334e88208321b277c33c3c.1633727270.git.jonathantanmy@google.com> (raw)
In-Reply-To: <cover.1633727270.git.jonathantanmy@google.com>

In a35e03dee0 ("submodule: lazily add submodule ODBs as alternates",
2021-09-08), Git was taught to add all known submodule ODBs as
alternates when attempting to read an object that doesn't exist, as a
fallback for when a submodule object is read as if it were in
the_repository. However, this behavior wasn't restricted to happen only
when reading from the_repository. Fix this.
