Subject: [PATCH 1/2] fix passing a name for config from submodules
Date: Tue, 26 Jul 2016 11:49:13 +0200 [thread overview]
Message-ID: <20160726094913.GA3347@book.hvoigt.net> (raw)
In-Reply-To: <xmqq60rt933m.fsf@gitster.mtv.corp.google.com>
In commit 959b5455 we implemented the initial version of the submodule
config cache. During development of that initial version we extracted
the function gitmodule_sha1_from_commit(). During that process we missed
that the strbuf rev was still used in config_from() and now is left
empty. Lets fix this by also returning this string.
