Subject: [RFC PATCH 4/4] submodule: cache superproject gitdir during 'update'
Date: Fri, 11 Jun 2021 15:54:28 -0700 [thread overview]
Message-ID: <20210611225428.1208973-5-emilyshaffer@google.com> (raw)
In-Reply-To: <20210611225428.1208973-1-emilyshaffer@google.com>
A cached path to the superproject's gitdir might be added during 'git
submodule add', but in some cases - like submodules which were created
before 'git submodule add' learned to cache that info - it might be
useful to update the cache. Let's do it during 'git submodule update',
when we already have a handle to the superproject while calling
operations on the submodules.
