Subject: [PATCH v2 3/7] fetch: avoid reading submodule config until needed
Date: Tue, 11 Aug 2020 15:52:18 -0700	[thread overview]
Message-ID: <8b4a522a13089ea144e922280f1c71a4ec3afa1f.1597184949.git.jonathantanmy@google.com> (raw)
In-Reply-To: <cover.1597184948.git.jonathantanmy@google.com>

Teach "git fetch" to avoid reading the submodule config until necessary.
This allows users to avoid the lazy-fetching of this potentially missing
config file by specifying the --recurse-submodules=no command line
option.
