Subject: [PATCH 07/14] update submodules: introduce is_interesting_submodule
Date: Tue, 14 Feb 2017 16:34:16 -0800 [thread overview]
Message-ID: <20170215003423.20245-8-sbeller@google.com> (raw)
In-Reply-To: <20170215003423.20245-1-sbeller@google.com>
In later patches we introduce the --recurse-submodule flag for commands
that modify the working directory, e.g. git-checkout.
It is potentially expensive to check if a submodule needs an update,
because a common theme to interact with submodules is to spawn a child
process for each interaction.
So let's introduce a function that pre checks if a submodule needs
to be checked for an update.
