Updating drupal without file access
A few days ago, it was brought to my attention that something had been broken on the PHP-GTK community site during the 5.0 RC2 upgrade. The problem was easily identified as being codefilter.module
having been removed during the upgrade and not reinstalled. Of course, not being at my office, I did not have access to the FTP passwords, but just to my admin account, and I did not want to leave the community members in the cold, so I used this small trick.
