Yes, I've a lot of refcounts leaks.
any chance that this is the same problem that andy is running
into (read his

I dunno because of my very lack of knowledge of Zope.
All of these refcounts leaks means that the Product is doing something wrong

Hello guys,
It seems that I've some memory leak problems and I want to
understand where
I've to look for.
Scenario:
I've an IIS web server that generates an XML page (taking data from
SqlServer);
The Zope web server must retrieve the XML page, manage the
data and render
them in HTML (I cant only apply a XSL stylesheet to XML).
The Facts:
I've written a external method that - using httplib - reads
the XML page and
return a string that is the raw XML sources, than I've
written another
external method that use ExpatBuilder of
Products.ParsedXML.DOM to parse the
XML an generate a list of [(id - {mapping})] which will be
accessed with a
dtml-in tag, so in the sequence-key I've access to the ID and with
sequence-item I can access to the mapping object.
I'm using latest version of ZOPE (2.3.1, the binary one
with Python 1.5.2)
and ParsedXML.
The Problem:
It seems that every time the method retrieve the page or
parse the XML I
loose a bunch of kilobytes. Because the methods are very
simple (100 lines
of code in total) and because I didn't create any class for
handling this
workflow I can't understand where I can loose bytes.
The Questions:
Is the list generated for the dtml-in tag freed
automatically by ZOPE ?
Is there a Garbage Collector somewhere that must be activated ?
Should I avoid the use of the ExpatBuilder for XML processing ?
Thanks for listening my newbies questions.

Re: [Zope-dev] memory leak
Hi Marco,
This looks like a potential bug in either ParsedXML or the code you're using
to manipulate the components within ParsedXML.
We'd like to find out! ;-) Do you think you can file a collector report
with enough information in it to reproduce this behavior?
Many thanks,

[Zope-dev] How do I call an HTMLFile in context provided by a path?
Hi,
I have a method that receives a path:
'/MyApp/SomeSpecialist/some_id/edit_html' and has to call edit_html
in the context of some_id. If edit_html is a DTML Method, I can do
this:
obj = REQUEST.traverse(path)
return obj(obj.aq_parent, REQUEST)
But when edit_html is an HTMLFile in a Python Product, obj.aq_parent
doesn't work. And trying to get some_id using
REQUEST.traverse('/MyApp/SomeSpecialist/some_id') returns the
index_html method of some_id, instead of the object itself.
Any ideas how I can fix this?
TIA, Itai

Re: [Zope-dev] memory leak
The bugreport won't do us as much good if we need to set up an elaborate
testing environment... it'd be preferable if you could break it down enough
to make it happen in a single external method or pythonscript that doesn't
rely on external webservers or databases, or what-have-you... but we'll take
whatever you've got!

RE: [Zope-dev] ActiveState / DC Collaboration
Will there be an effort to make Zope 2.3.x play with ActivePython 2.0 or is this a longer range goal ... Zope 3.x ???

If edit_html is a DTML Method, I can do this: obj = REQUEST.traverse(path) I would use "restrictedTraverse" instead of "REQUEST.traverse" as it uses less magic. Thanks for the tip... I thought restrictedTraverse is slower because it has to do security checks? ... But when edit_html is an HTMLFile in a Python Product, obj.aq_parent doesn't work. Why not? It causes this exception: Error Type: AttributeError Error Value: edit_htmlaq_parent This would mean that either your product is not derived from ExtensionClass.Base or that "HTMLFile" is not derived from "Acquisition.Implicit". My product inherit does have implicit acquisition. But HTMLFile doesn't - that's the whole problem. Replacing HTMLFile with DTMLFile solves the problem, as DTMLFile derives from Acquisition.Explicit.

[Zope-dev] Using Python script to create ZClass instances
Hi there,
Im having problems using Python script to create a ZClass instance from
a ZClass that's inside of another ZClass. I have this addMyObject
Python script as constructor script for "Scriptable Type Information"
type object (CMF):
## Script (Python) "addMyObject"
##bind container=container
##bind context=context
##bind namespace=
##bind script=script
##bind subpath=traverse_subpath
##parameters=folder, id
##title=
##
folder.Control_Panel.Products.MyProducts.MyObjects.MyObject_add(id)
# folder.manage_addProduct('MyProduct')... doesn't work either
item = getattr(folder, id)
return item
MyObjects is a ZClass that contains MyObject. The error I get is:
Zope error
Error type AttributeError
Error value MyObjects
There should be some explanation somewhere how to access resources
inside of Control_Panel, but I fail to find it. Creating objects is
very confusing and difficult at times...
Bye,
