Add (currently failing) test for atomic actions Actions via the web-interface can have several database-modifying instructions. These should be atomic, i.e., either all should go in or none. This is currently not the case due to commit calls from OTK handling (CSRF-protection).

def audit_html_files(db, cl, nodeid, newvalues):
    if newvalues.has_key('type') and newvalues['type'] == 'text/html':
        newvalues['type'] = 'text/plain'
    

def init(db):
    db.file.audit('set', audit_html_files)
    db.file.audit('create', audit_html_files)
