I was trying to do a svn cleanup because I can\'t commit the changes in my working copy, and I got the following error:
sqllite: databas
First, open command/terminal at repository root (folder which has .svn as child folder):
cd /path/to/repository
Download sqlite3 and put executable sqlite3 at root of folder.
You do an integrity check on the sqlite database that keeps track of the repository (/path/to/repository/.svn/wc.db):
sqlite3 .svn/wc.db "pragma integrity_check"
That should report some errors.
Then you might be able to clean them up by doing:
sqlite3 .svn/wc.db "reindex nodes"
sqlite3 .svn/wc.db "reindex pristine"
If there are still errors after that, you still got the option to check out a fresh copy of the repository to a temporary folder and copy the .svn folder from the fresh copy to the old one. Then the old copy should work again and you can delete the temporary folder.
