Hello,
Looking at nova.git for the first time, I cloned it.
Surprised that it was so much larger than the others, and too large for
the size of the source and the amount of history, I tried to compress it.
That reduced the repository size from nearly 100MiB to just 30:
$ git clone git://github.com/openstack/nova.git
$ git-repo-compress .git
97M .git

30M .git
The command I used is just a wrapper around git repack:
git-repo-compress () {
local d=$1
du -sh "$d"
start=$(date)
env time git --git-dir="$d" repack -afd --window=250 --depth=250
echo started $start
date
du -sh "$d"
}
Future cloners (and those who push, too) will be
grateful if someone with access to the server would
do the same thing to the public nova.git repository.
Compressing the repo improves server performance, too.
These other repositories compressed well, too:
size of .git repo (MiB)
current compressed
swift 9.8M 2.3M
keystone 11M 9.9M
horizon 4.1M 3.2M
glance 5.2M 1.9M
quantum 3.0M 1.4M
