Converting Objects to strings
by Jason Spisak 29 Mar '99

29 Mar '99

I am trying to turn ZopeTime (an object) into a string (or integer). Does anybody know how to do it without leaving DTML? I am using this as an arbitrary ID generator for new objects whose ID must be unique. All the best, Jason Spisak webmaster(a)mtear.com

Possible bug in CopySupport.py (Zope 1.10.2)
by Stefan Franke 29 Mar '99

29 Mar '99

In CopySupport.py CopyContainer._verifyObjectPaste is called by manage_renameObject with a REQUEST object passed. If REQUEST is None in manage_renameObject (the default when not called interactively) _verifyObjectPaste tries to access a user=REQUEST.get('AUTHENTICATED_USER', None) in line 326 (I have no CVS, so this is the std 1.10.2 distribution). Since REQUEST is None an AttributeError is thrown. * * * What I was trying to do is to customize the automatic renaming of object ids (if pasted) via an overloaded _postCopy. I don't know how to solve the above authentication problem (at least as intended) other than by passing the REQUEST object over to _postCopy. Ideas anyone? Stefan

I spoke to soon... but I've figured out a fix and I'd like to bounce it off the group to see if you'd think it'd break anything. The fix was to modify AccessControl.User.validate()... here's a unified diff showing what I changed... @@ +390,10 -388,7 @@ # Try to get user user=self.getUser(name) if user is None: + if self._isTop(): + return self._nobody + else: + return None - return None Key: self._nobody returns the Anonymous User object self.getUser tries to get the user object from an acl_users folder The problem I was having, was that validate() was getting passed the authentication information for the person who was defined in a subfolder which it didn't have access to... so... the validate would return none, which would raise the Unauthorized error. By having it return the Anonymous User object (only at the top level), it allows access to public areas without sacrificing security. Does this make sense... does anyone see any potential problems?

NT Service
by htrd90＠zepler.org 28 Mar '99

I am looking to run Zope as an NT service, but ideally without IIS. Has anyone had ZopeHTTPServer running as a service? or is there a better way?

Pickling class dictionaries?
by Stefan Franke 26 Mar '99

26 Mar '99

How is the dictionary of a Products class object treated by BoboPOS? I'm thinking of using an existing class, which keeps an inventory of its instances (I'm sure there was a pattern name for this...) as a basis for a Product, and wonder if it is feasible. Python's std lib documentation is a little ambigous about this: First, it says "Note that when class instances are pickled, their class's code and data are not pickled along with them. Only the instance data are pickled." Later then: "The following types can be pickled: [...] - classes that are defined at the top level in a module " Can anyone light things up? Stefan

Zope2 is really just a milestone of when a number of things will have happened -- primarily, providing concurrency via: o concurrent publishing via ZServer o concurrent database storage via ZODB3 o ensuring the base objects in Zope are concurrency-friendly When these things happen, Zope2 is done. --Paul

Doing a CVS checkout is obviously a perfectly safe activity -- you'll just get a bunch of code in a directory different from your live app. You can then make areas to work in, browse the code, look at the CVS logs, etc. Its only when you connect this code to your existing setup that you need to be careful. --Paul
