[Zope] ZCatalog + Virtual Hosting = Trouble

[Edmund Goppelt]

It seems a well established fact that ZCatalog does not work properly
with virtual hosting.  I've tried Evan Simpson's ZCatalog patch, but
to no avail:


***DOES NOT WORK
   def resolve_url(self, path, REQUEST):
       """
       Attempt to resolve a url into an object in the Zope
       namespace. The url may be absolute (site-relative) or a catalog path
       style url. If no object is found, None is returned.
       No exceptions are raised.
       """
       pparts = filter(None, string.split(path, '/'))
       try:
            obj = getattr(self.aq_parent, pparts.pop(0))
            while pparts:
                  obj = obj[pparts.pop(0)]
            return obj
       except:
            return    


The following *does* seem to work.  Can someone tell me why?  Are
there any nasty side effects I should know about, or is this a good
way of getting ZCatalog to play nice with Virtual Hosting?

***WORKS

        """

        namespace. The url may be absolute or a catalog path
        style url. If no object is found, None is returned.
        No exceptions are raised.
        """
        pparts=filter(None, string.split(path, '/'))
        try:
            obj=getattr(self.aq_parent, pparts.pop(0))
            while pparts:
                obj=getattr(obj, pparts.pop(0))
            return obj
        except:
            return
