Subject: [PATCH 0/3] some prune optimizations
Date: Wed, 13 Feb 2019 23:31:28 -0500	[thread overview]
Message-ID: <20190214043127.GA19019@sigill.intra.peff.net> (raw)

Here are two optimizations for git-prune that we've been running at
GitHub for ages. No particular reason to share them now; they just
finally floated to the top of my todo pile. Do note that I rebased and
polished them (and the third one is brand new), so the concepts are
proven, but it's possible I introduced a new bug. ;)

  [1/3]: prune: lazily perform reachability traversal
  [2/3]: prune: use bitmaps for reachability traversal
  [3/3]: prune: check SEEN flag for reachability
