Pushed out a minor release of git-annex today, mostly to fix build problems on Debian. No strong reason to upgrade to it otherwise.
Continued where I left off with the Git.Destroyer. Fixed quite a lot of edge cases where git repair failed due to things like a corrupted .git/HEAD file (this makes git think it's not in a git repository), corrupt git objects that have an unknown object type and so crash git hard, and an interesting failure mode where git fsck wants to allocate 116 GB of memory due to a corrupted object size header. Reported that last to the git list, as well as working around it.
At the end of the day, I ran a test creating 10000 corrupt git repositories, and all of them were recovered! Any improvements will probably involve finding new ways to corrupt git repositories that my code can't think of.
