since i am using google code to host my svn repo, so Delete file contents from SVN history cannot solve my problem, because i cannot run svndump and svndumpfilter command on google code.
[mirror@home ins_ssh]$ svnadmin dump https://xxx.googlecode.com/svn/
svnadmin: 'https://xxx.googlecode.com/svn' is an URL when it should be a path
so is that possible to delete large binary files from google code's svn history?
especially when some sensitive data is commited to svn repo.
