Subject: [PATCH 3/4] list-objects: optimize "revs->blob_objects = 0" case
Date: Wed, 5 Jun 2013 18:40:05 -0400 [thread overview]
Message-ID: <20130605224004.GC15607@sigill.intra.peff.net> (raw)
In-Reply-To: <20130605223551.GF8664@sigill.intra.peff.net>
If we are traversing trees during a "--objects"
traversal, we may skip blobs if the "blob_objects" field of
rev_info is not set. But we do so as the first thing in
process_blob(), only after we have actually created the
"struct blob" object, incurring a hash lookup. We can
optimize out this no-op call completely.
This does not actually affect any current code, as all of
the current traversals always set blob_objects when looking
at objects, anyway.
