Subject: [PATCH 3/3] bigfile/filter: only update MD5 if non-nil
Date: Mon, 14 Sep 2015 10:24:51 +0000 [thread overview]
Message-ID: <20150914102451.647-4-e@80x24.org> (raw)
In-Reply-To: <20150914102451.647-1-e@80x24.org>
It is possible to disable MD5 verification, so we cannot risk
updating a nil object.
Also, favor explicitly calling "update" instead of using "<<" which
YARV will attempt to optimize for Array/String receivers at the cost
of other objects (such as Digest::MD5)
