git svn .git/svn/*/index files taking up huge amounts of disk space

git svn .git/svn/*/index files taking up huge amounts of disk space

[Robert Zeh]

I have recently imported  a Subversion repository with   
1.6.4.rc0.17.gd9eb0, and ran into an interesting tidbit.  The .git/svn  
directory is the largest directory, taking up about twice as much  
space as the .git/objects directory.

Most of the space is taken up by index files under .git/svn under .git/ 
svn/tag or .git/svn/<branch name> directories in the subversion tree.

The repository uses the normal Subversion layout (trunk/tags/branches)  
and was setup with git svn init -s.  There are a lot of tags in the  
repository - about one per day for the past several years.

What are the index files under .git/svn used for?  Am I doing anything  
wrong?  Can the index files under .git/svn be safely removed?  My  
brief look at git-svn.perl makes me think that they are temporary, but  
I'm not sure.

Thanks,
Robert

The index files are used to keep track of the commits that came from
svn, so that git-svn rebase knows where to start from (either when
committing or when doing a fetch from svn).

Unless you used the --no-metadata switch, the files under .git/svn can
be safely removed (at the cost of performance when operating a branch
that has had its index removed).
