Subject: [PATCH 8/9] revision.c: use bloom filters to speed up path based revision walks
Date: Fri, 20 Dec 2019 22:05:19 +0000 [thread overview]
Message-ID: <72a2bbf6765a1e99a3a23372f801099a07fe11a5.1576879520.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.497.git.1576879520.gitgitgadget@gmail.com>
From: Garima Singh <garima.singh@microsoft.com>
If bloom filters have been written to the commit-graph file, revision walk will
use them to speed up revision walks for a particular path.
Note: The current implementation does this in the case of single pathspec
case only.
We load the bloom filters during the prepare_revision_walk step when dealing
with a single pathspec. While comparing trees in rev_compare_trees(), if the
bloom filter says that the file is not different between the two trees, we
don't need to compute the expensive diff. This is where we get our performance
gains.
Performance Gains:
We tested the performance of `git log --path` on the git repo, the linux and
some internal large repos, with a variety of paths of varying depths.
On the git and linux repos:
we observed a 2x to 5x speed up.
On a large internal repo with files seated 6-10 levels deep in the tree:
we observed 10x to 20x speed ups, with some paths going up to 28 times faster.
RFC Notes:
I plan to collect the folloowing statistics around this usage of bloom filters
and trace them out using trace2.
- number of bloom filter queries,
- number of "No" responses (file hasn't changed)
- number of "Maybe" responses (file may have changed)
- number of "Commit not parsed" cases (commit had too many changes to have a
bloom filter written out, currently our limit is 512 diffs)
