Subject: [PATCH/WIP v3 00/31] Make git-am a builtin
Date: Thu, 18 Jun 2015 19:25:12 +0800 [thread overview]
Message-ID: <1434626743-8552-1-git-send-email-pyokagan@gmail.com> (raw)
This patch series depends on pt/pull-builtin for OPT_PASSTHRU_ARGV() and
argv_array_pushv().
This is a re-roll of [WIP v3]. Thanks Junio and Stefan for the reviews last
round.
The biggest addition this round would be the support for git-rebase. Here's
a small unscientific benchmark that rebases 50 patches:
git init &&
echo initial >file &&
git add file &&
git commit -m initial &&
git tag initial &&
for x in $(seq 50)
do
echo $x >>file &&
git commit -a -m $x
done &&
git checkout -b onto-rebase initial &&
git commit --allow-empty -mempty &&
time git rebase -q --onto onto-rebase initial master
With master:
1.53s, 1.55s, 1.17s, 1.52s, 1.22s. Avg: ~1.40s
With master + this patch series:
0.22s, 0.22s, 0.18s, 0.21s, 0.18s. Avg: ~0.20s
So this is around a 6-7x speedup.
Previous versions:
[WIP v1] http://thread.gmane.org/gmane.comp.version-control.git/270048
[WIP v2] http://thread.gmane.org/gmane.comp.version-control.git/271381
git-am is a commonly used command for applying a series of patches from a
mailbox to the current branch. Currently, it is implemented by the shell script
git-am.sh. However, compared to C, shell scripts have certain deficiencies:
they need to spawn a lot of processes, introduce a lot of dependencies and
cannot take advantage of git's internal caches.
This WIP patch series rewrites git-am.sh into optimized C builtin/am.c, and is
part of my GSoC project to rewrite git-pull and git-am into C builtins[1].
