Unable to extract revision information from commit

Question

Just noticed a scary problem with git svn (git version 1.6.5.2).
First commiting my work as normal with git commit, when finished I did git svn dcommit.
This started fine with Resetting to the latest refs/remotes/git-svn but then failed and returned the error Unable to extract revision information from commit.

This left all files that changed in between the last svn dcommit and the current git version unstaged and all git log messages in between are also gone.

Now, is there a way to get the git commits with log messages back?

Answer 1

Check git reflog, one of the last entries in there will point to the commit you are looking for.

If all else fails, you can use the recover-anything approach.
