Subject: [PATCH 16/28] attr: add counted string version of git_attr()
Date: Mon, 10 Oct 2016 17:21:03 -0700 [thread overview]
Message-ID: <20161011002115.23312-17-sbeller@google.com> (raw)
In-Reply-To: <20161011002115.23312-1-sbeller@google.com>
From: Junio C Hamano <gitster@pobox.com>
Often a potential caller has <name, namelen> pair that
represents the name it wants to create an attribute out of.
When name[namelen] is not NUL, the caller has to xmemdupz()
only to call git_attr().
Add git_attr_counted() that takes such a counted string instead of
"const char *name".
