Subject: [PATCH v1] add test to demonstrate that shallow recursive clones fail
Date: Thu, 12 Nov 2015 10:04:09 +0100	[thread overview]
Message-ID: <1447319049-51371-1-git-send-email-larsxschneider@gmail.com> (raw)

From: Lars Schneider <larsxschneider@gmail.com>

"git clone --recursive --depth 1 --single-branch <url>" clones the
submodules successfully. However, it does not obey "--depth 1" for
submodule cloning.

The following workaround does only work if the used submodule pointer
is on the default branch. Otherwise "git submodule update" fails with
"fatal: reference is not a tree:" and "Unable to checkout".
git clone --depth 1 --single-branch <url>
cd <repo-name>
git submodule update --init --recursive --depth 1
