Subject: [PATCH v4 00/15] diff --color-moved[-ws] speedups
Date: Tue, 16 Nov 2021 09:49:23 +0000 [thread overview]
Message-ID: <pull.981.v4.git.1637056178.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.981.v3.git.1635336262.gitgitgadget@gmail.com>
Changes since V3:
* Patch 1 now allows the user to choose different endpoints for the diff
perf tests to facilitate testing with different repositories.
* Fixed the alignment of the perf results column headers in a couple of
patches.
Changes since V2:
* Patches 1-3 are new and fix an existing bug.
* Patch 8 includes Peff's unused parameter fix.
* Patch 11 has been updated to fix a bug fix in V2.
* Patch 13 has an expanded commit message explaining a change in behavior
for lines starting with a form-feed.
* Updated benchmark results.
The bug fix in patch 3 degrades the performance, but by the end of the
series the timings are the same as V2 - see the range diff.
V2 Cover Letter: Thanks to Ævar and Elijah for their comments, I've reworded
the commit messages, addressed the enum initialization issue in patch 2 (now
3) and added some perf tests.
There are two new patches in this round. The first patch is new and adds the
perf tests suggested by Ævar, the penultimate patch is also new and coverts
the existing code to use a designated initializer.
I've converted the benchmark results in the commit messages to use the new
tests, the percentage changes are broadly similar to the previous results
though I ended up running them on a different computer this time.
V1 cover letter:
The current implementation of diff --color-moved-ws=allow-indentation-change
is considerably slower that the implementation of diff --color-moved which
is in turn slower than a regular diff. This patch series starts with a
couple of bug fixes and then reworks the implementation of diff
--color-moved and diff --color-moved-ws=allow-indentation-change to speed
them up on large diffs. The time to run git diff --color-moved
--no-color-moved-ws v2.28.0 v2.29.0 is reduced by 33% and the time to run
git diff --color-moved --color-moved-ws=allow-indentation-change v2.28.0
v2.29.0 is reduced by 88%. There is a small slowdown for commit sized diffs
with --color-moved - the time to run git log -p --color-moved
--no-color-moved-ws --no-merges -n1000 v2.29.0 is increased by 2% on recent
processors. On older processors these patches reduce the running time in all
cases that I've tested. In general the larger the diff the larger the speed
up. As an extreme example the time to run diff --color-moved
--color-moved-ws=allow-indentation-change v2.25.0 v2.30.0 goes down from 8
minutes to 6 seconds.
Phillip Wood (15):
diff --color-moved: add perf tests
diff --color-moved: clear all flags on blocks that are too short
diff --color-moved: factor out function
diff --color-moved: rewind when discarding pmb
diff --color-moved=zebra: fix alternate coloring
diff --color-moved: avoid false short line matches and bad zerba
coloring
diff: simplify allow-indentation-change delta calculation
diff --color-moved-ws=allow-indentation-change: simplify and optimize
diff --color-moved: call comparison function directly
diff --color-moved: unify moved block growth functions
diff --color-moved: shrink potential moved blocks as we go
diff --color-moved: stop clearing potential moved blocks
diff --color-moved-ws=allow-indentation-change: improve hash lookups
diff: use designated initializers for emitted_diff_symbol
diff --color-moved: intern strings
