Subject: [PATCH] fast-import: Don't count delta attempts against an empty buffer
Date: Sun,  1 Jul 2018 06:41:06 +0900	[thread overview]
Message-ID: <20180630214106.19848-1-mh@glandium.org> (raw)

When the reference buffer is empty, diff_delta returns NULL without
really attempting anything, yet fast-import counts that as a delta
attempt.
