Sorry Nicolas,
Completely missed your message amongst the torrent of the git mailing
list - which I'm now unsubscribed from.. But sure, I'll ad this to my
todo list :)
Cheers,

Blog post about git pruning history and finding large objects in

This is a script I put together after migrating the Spring Modules
project
from CVS, using git-cvsimport (which I also had to patch, to get to
work on OS
X / MacPorts). I wrote it because I wanted to get rid of all the
large jar
files, and documentation etc, that had been put into source
control. However,
if _large files_ are deleted in the latest revision, then they can
be hard to
track down.
#!/bin/bash
#set -x
# Shows you the largest objects in your repo's pack file.
# Written for osx.

# @author Antony Stubbs
# set the internal field spereator to line break, so that we can
iterate
easily over the verify-pack output
IFS=$'\n';
# list all objects including their size, sort by size, take top 10
objects=`git verify-pack -v .git/objects/pack/pack-*.idx | grep -v
chain |
sort -k3nr | head`
echo "All sizes are in kB's. The pack column is the size of the
object,
compressed, inside the pack file."
output="size,pack,SHA,location"
for y in $objects
do
# extract the size in bytes
size=$((`echo $y | cut -f 5 -d ' '`/1024))
# extract the compressed size in bytes
compressedSize=$((`echo $y | cut -f 6 -d ' '`/1024))
# extract the SHA
sha=`echo $y | cut -f 1 -d ' '`
# find the objects location in the repository tree
other=`git rev-list --all --objects | grep $sha`
#lineBreak=`echo -e "\n"`
output="${output}\n${size},${compressedSize},${other}"
done
echo -e $output | column -t -s ', '
This is certainly useful. Mind submitting a patch adding this
script to
contrib/stats/ ?
