RE: Huge pack file from small unpacked objects

RE: Huge pack file from small unpacked objects

[Nick Triantos]

Hi,

I recently created a repo from SVN via git-svn.  The bare repo was about ~600MB.  I cloned it, and on the clone, I added 2 small files (.gitignore and .gitattributes) to a branch, merged them to master, and pushed that back to the origin.  The cloned repo remains at about 600MB, while my origin repo (the one from svn) is now about 2.4GB.  I found that it created a file in objects/pack which accounts for this huge size.

I've tried running 'git repack -a -d' but that didn't shrink the size of this pack file.

Any ideas why the pack file is so huge?  Anything I can do to shrink it?  My coworkers are understandably unhappy that the repo is so huge now (makes for very slow pulls)

thanks,
-Nick

Huge pack file from small unpacked objects

Have you tried "git prune"?

This is rather weird.

Any chance the original repository could be downloaded somewhere in 
order to attempt reproducing this issue?

I've tried running 'git gc' (which should be pruning) and that hasn't helped.

Is there an easy way to unpack the pack file and see what's inside (including sizes)?

thanks,

Unpack?

    (mkdir /var/tmp/junk &&
     cd /var/tmp/junk &&
     git init && git unpack-objects) <.git/objects/pack/pack-$that_one.pack

It might also be interesting to see

    git verify-pack -v .git/objects/pack/pack-$that_one.pack
