Here's how to obliterate files from the repository. Note that using
the subversion remove command will not remove it from your
repository. I had to use it as I noticed I put friends' e-mail
addresses in by accident.
The following commands move the repository to a backup location, dumps
the database in a file. Finally I remove the file .nobunce from the
repository. You can specify multiple files to remove.
mv subversion subversion.bak svnadmin dump subversion.bak > dump svndumpfilter exclude trunk/ivan/.nobounce < dump > dump.filter
Now I recreate a fresh repository and load the new new dump file minus
the offending file. You can delete subversion.bak when you feel
confident that your new repository is working.
svnadmin create --fs-type fsfs subversion svnadmin load subversion < dump.filter
According to the subversion documentation, there will be a command
called obliterate that will do the above without the hassle.
