This is a script which tries to recover incomplete git repositories:

• Iterate through all commit-objects of a repository
• Try to restore the contents of the commit
• Commits are not sorted by date

bash extractor.sh /tmp/mygitrepo /tmp/mygitrepodump

where

• /tmp/mygitrepo contains a .git directory
• /tmp/mygitrepodump is the destination directory

This can be used in combination with the Git Dumper in case the downloaded repository is incomplete.
