Here is a summary of the solution I used. I'm a beginner in git
and just summarizing what others told me and what I did. Use at
your own risk!
1. Remove anything you know should be removed, e.g.:
git filter-branch --tree-filter 'find . -regex ".*toolchain\..*" -exec
rm -f {} \;' HEAD
2. Expire the log:
git reflog expire --all
3. Delete stuff from .git that should be manually "verified" to be
correct. I don't actually
know how to "verify" that at this point... Use backups Luke!
rm -rf .git/refs/original
# delete lines w/"refs/original" from .git/packed-refs
vi .git/packed-refs
# for good measure...
git reflog expire --all
git gc
4. Your repository is still huge. By creating a new repository and pulling from
this one, the garbage will stay in the old one...
mkdir newrep
cd newrep
git init
git pull file:///oldrep
5. Check size of .git. If it is still too big, try figuring out which
files that are big by looking at the packs(.git/objects/pack/xxx):
$ git verify-pack -v $PACK | grep -v "^chain " | sort -n -k 4
and then for the last few lines do a
$ git rev-list --all --objects | grep $SHA1
6. Go back to #1 until done.
Your repository should now be of reasonable size...
I've found some great scripts for converting from svn/cvs, but really
the above procedure
is necessary to run when converting nasty old repositories...
