I'm trying to create a Rack-mountable Image class but I'm having a lot of trouble getting a class subclassed from Image and DataSkin to work. Having some working code could save me some trouble. I only need the basic RackImage, without all the later stuff you added relating to Renderings.

[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,

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.

I do not know "ParsedXML"'s DOM implementation. However, cycles are quite common for DOM's due to the cyclic relationship between parent and children.

Are you parsing the XML and creating this list from the DOM objects,
and then throwing them away? Or are you parsing the XML and creating
this list from your pyexpat interface code, and never accessing the
DOM objects?
In either case, it seems like you shouldn't be using ParsedXML's
ExpatBuilder, which is an interface to PyExpat which is made to create
ParsedXML's DOM objects. You should be using your own PyExpat
interface to parse this information from your XML input, without the
overhead of generating a DOM tree that you're just going to throw
away. The interface is documented in the XML-SIG topic area on
python.org, and our ExpatBuilder should be a good example on how to
interface with our PyExpat installation - just don't build the DOM if
you don't use it.
Regardless of what you *should* be doing :), or if I'm misreading you,
if you aren't keeping references to the DOM objects being created,
then they should be reclaimed by the GC, and you do seem to have DOM
objects lying around. I'd like to see your code, is it short enough
to post? Or you can chuck it into the collector or ParsedXML tracker.
For debugging purporses, I'd suggest simplifying by supplying an XML
string directly, rather than from an external server.

We aren't using circular refs in our DOM, so we don't have any way to release a DOM object - losing or deleting the reference should do it. If this isn't happening when the reference is going away, then this is either a Zope bug or a ParsedXML bug.

Re: [Zope-dev] ZODBCA questions...
;-) I think it's been kept out of triage for a while now while we've worked on getting our Catalog story straight, releasing CMF, getting ZEO to 1.0, and improved documentation. Sorry, I forget that folks aren't omniscient, and make assumptions that people know where DC's priorities are right now. Good places to get a sense of this at a high level are the "Zope Roadmap" at http://dev.zope.org/Resources/ZopeRoadmap.html and the "Zope Directions" document at http://dev.zope.org/Resources/ZopeDirections.html . On a more micro-level, a preliminary list of features planned for the next major release are at http://dev.zope.org/Resources/zope_240_plan.html . We're trying to make sense out of the current state of our relational stuff, thus the database strategy document. Hopefully we'll be able to commit resources to it to freshen it up a bit... until it gets onto the roadmap, however, we're relying (probably too much) on the community to summarize (and maybe even fix!) the problems in, for example, the current ZODBCDA implementation.

This would be a great solution, but I dont think I can devote any time to it all. Is the WISE installation script available for patching?

> Will the python you distribute for windows be bare bones (without header > files like the current version) ? I had assumed so, though if someone cares enough to champion the effort, that could be changed. Right now, the windows distribution is really geared toward the crowd that really doesn't know and doesn't care about Python distributions, etc. It is intended to "just work" in a way that doesn't require the user to know anything and that doesn't interfere with any other Python things that may or may not be on their system. The downside, of course, is that we currently don't have an easy way (at least not as easy as the no-brainer dist) for people who do know and do care about Python installations to set things up to work with their current Python.

Re: [Zope-dev] Tracking memory leak
If you're talking about ZSQLMethod options then its at the default which is Maximum results to cache 100 Maximum time (sec) to cache 0 Does that mean the first 100 results are being cached for ever?

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!

I can send you the code for the two external method I use, they only need a
webserver (that could be zope too) that serve an XML page (I can provide the
XML the methods needs) and the bunch of dtml methods I use to show the XML.
Anyway I will try to understand what's happening with ParsedXML and my code.

I can send you the code for the two external method I use, they only need a
webserver (that could be zope too) that serve an XML page (I can provide the
XML the methods needs) and the bunch of dtml methods I use to show the XML.
Anyway I will try to understand what's happening with ParsedXML and my code.

[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
