After updating to the latest CVS I get errors in the attached log file upon the initial load of my app, which uses guard and SessionWrapper for authentication. portal = login.RatControlPortal(realm) # Allow anonymous access. portal.registerChecker(AllowAnonymousAccess(), IAnonymous) # Allow users registered in the password file. portal.registerChecker(FilePasswordDB(sibpath(__file__, "passwords.txt"))) site = appserver.NevowSite( resource=SessionWrapper( UsernamePasswordWrapper(portal, callback=utility.loginCallback) ), ) I can try to get a tac together if needed, but the most recent changes in CVS looked like they might have caused the problem. Just wanted to give you some idea of what my code looks like. -Justin
