Prototyped folders?
by Hamish Lawson 28 Jun '00

28 Jun '00

If a folder doesn't itself contain a required object or method, I'd like to have another folder looked in instead. The fall-back folder won't necessarily (and often can't) be higher in the hierarchy, so acquisition doesn't seem to be a solution. Inheritance from a folderish class seems to be one solution, but I fear this might lead to an explosion of classes. The answer I think I need is to have a protoype mechanism (similar to that used in JavaScript and Self). A folder with the requirement to have its missing methods looked for elsewhere would be created as an instance of (say) PrototypedFolder with a pointer to the folder it wanted to use as a prototype. Does such a mechanism exist for Zope? Hamish Lawson University of St Andrews, Scotland ____________________________________________________________ Do You Yahoo!?

how to get email delivery errors
by Dan Rusch 27 Jun '00

27 Jun '00

Our site allows supervisors to email orders back to sales reps. We have this working very well. The problem is if the supervisor types in an non-existant email address we aren't getting Mail System Error - Returned Mail messages like you would from other email apps such as Netscape Messenger. Does anyone know how to accomplish this. Thanks, DR

This may have several reasons: * cannot append to the ZODB file (var/data.fs), * commit to a database failed (e.g. of an SQL database) * FSSession information could not be updated * ??? Somehow, your log lacks some info about the actual problem. I would add "import traceback; traceback.print_exc()" at line 279 of "ZODB/Transaction.py" and look at the output. This should give you more detailed information about the problem. > I also get the following error on occassion when calling FSSession: > Error Type: EOFError > Error Value: It seems that FSSession wants to read past the end of the file and gets an EOFError. That's strange, because Python usually indicates EOF by returning an empty string and not by raising EOFError. I do not have FSSession sources. I would probably look at line 142 of "FSSession.py" to determine which operation raised the exception. Dieter

The parent chain is build up during URL traversal. Thus, it contains the ancestors in your Zope hierarchy. It does not depend on any ZClass relationships. Dieter

In your case, it got a string instead. You should either use a Z SQL Method with a single mapping object parameter or (exclusive) with keyword parameters. Dieter

ZODB/FSSession TransactionError
by Brian McClain 27 Jun '00

27 Jun '00

After playing around successfully with FSSession for a while, I ran into the following error when calling FSSession: Error Type: TransactionError Error Value: A serious error, which was probably a system error, occurred in a previous database transaction. This application may be in an invalid state and must be restarted before database updates can be allowed. Beware though that if the error was due to a serious system problem, such as a disk full condition, then the application may not come up until you deal with the system problem. See your application log for information on the error that lead to this problem.
