Subject: [PATCHv4 2/3] submodule: implement `name` as a builtin helper
Date: Tue, 1 Sep 2015 11:24:28 -0700 [thread overview]
Message-ID: <1441131869-29474-3-git-send-email-sbeller@google.com> (raw)
In-Reply-To: <1441131869-29474-1-git-send-email-sbeller@google.com>
This implements the helper `module_name` in C instead of shell,
yielding a nice performance boost.
Before this patch, I measured a time (best out of three):
$ time ./t7400-submodule-basic.sh >/dev/null
real 0m11.066s
user 0m3.348s
sys 0m8.534s
With this patch applied I measured (also best out of three)
$ time ./t7400-submodule-basic.sh >/dev/null
real 0m10.063s
user 0m3.044s
sys 0m7.487s
