[Zope-dev] Dataskin with no persistence.
Hi, I am trying to build a specialist which gives me access to a facade ZClass in front of a XML file. As the XML is already stored, I do not want to store the facade ZClass. Actually, I would like it to be a base on which the skinscript of the specialist's rack can add attributes. So I created a ZClass (HumanClass) with no properties inheriting from ZObject and _ZClass_for_DataSkin. I create a specialist in which the default rack has the following properties : data plug-in : a skinscript computing attributes based on an id and the xml. storage : Class to use for stored items: HumanClass Objects are: loaded by accessing attribute nom (which is defined in the skinscript) Store 'persistent' data: Directly in this object I store no HumanClass instance and try to get an instance : specialist.getItem(anId) I always get None. Am I trying to do something impossible because of lack of understanding or am I just wrong in one property of ZClass, Specialist, Rack ?

[Zope-dev] Custom dtml tag ... parameters not evaluated
Yo, I'm trying to create a custom dtml tag, and after the How-to on this (http://www.zope.org/Members/z113/1) that in itself posed no problem: easy as pie. The problem I'm having with the tag is that parameters are not evaluated. for instance (my tag's name is 'aa') dtml-let y="someValue" dmlt-aa role="y" ... /dtml-aa /dtml-let gives me in the code: role=="y" while I want it to be "someValue", playing with the quotes doesn't help either.

Hi all, I have a question on the security system of zope.

This means only logged in users like joe could wie the foo_doc. Now my question is: When joe is logged in in foo to view the foo_doc, and after that he view bar_doc he is authenticated as Anonymous in the bar_doc REQUEST (right??).

RE: [Zope-dev] memory leak
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. I've replaced ParsedXML's ExpatBuilder with the pyXML package and I used the sax parser without modifing the code (except for the import), this is the refcounts results.

Ok, so imagine a DTML method has an owner, and as the docs say the method can do no more than the authenticated user and the owner's permissions combined. So, now delete the owner. The DTML method will no longer be functional, since the owner does not exist, and has no permissions. I found this to be true with ZClass constructors at least.

RE: [Zope-dev] ActiveState / DC Collaboration
Someone with enough knowledge about how Python windows installs work and a rudimentary knowledge of WISE should be able to work it out so that the win32 distribution is willing to let you pick which Python to use if it sniffs one (or more) out on the target system. What about compiling all the extension modules for the right version of python? Realistically, we would have to require a certain version of Python be installed in order to use an existing installation. I think the real goal is to make it easier to use your own (correct version) Python install rather than to work magically with any Python that happens to be around. We should also make it easier for win32 to compile the extensions if they want to do something fancier than our installer supports.

Subject: [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...

[Zope-dev] getattr'ing proxy object's methods
I have a product with a proxy class for building objects which manage data for other objects. The proxy clients locate their proxy via meta_type, similar to a sql connection_id and use acquisition to establish parameters for each call. I want to pass method calls made to the clients directly to the proxy, but in the context of the client. Right now, my clients have a method: def Proxy(self): """Return the proxy associated with this object""" return getattr(self, self.proxy_id) which is used in conjunction with dtml-with to establish the context: dtml-with Proxy dtml-in "getTable(project=Project, [...])" This works fine, however, I would like for the clients to automatically pass method calls that they don't have on to the proxy. __setattr__ is not called for the proxy clients because the final URL component specifies an acquired folder method, not the proxy client. I tried __bobo_traverse__, but again, the final URL component is passed as the argument instead of the method, so it's not clear exactly how __bobo_traverse__ could make sense out of what needs to be done, much less know what method was to have been called. Is there a proper way to call a proxy object's method in this context, directly in the product class, without using dtml-with?

Hello all - [I'm intentionally cross-posting this because there are a number of folks using CVS that may read only one or the other] If you've looked at the dev.zope.org site lately, you have probably noticed a preliminary Zope 2.4 plan: http://dev.zope.org/Resources/zope_240_plan.html The major goal of Zope 2.4 will be to make Python 2.1 the officially supported (and required) Zope platform. A project dedicated to assessing what that involves has been started at: http://dev.zope.org/Wikis/DevSite/Projects/SupportPython21/FrontPage Enough progress has been made on identifying tasks that we want to start getting some things done. However, this will have an effect on those of you that are currently running from the Zope CVS. We are soon going to begin checking in changes to the head of the Zope CVS that will require the use of Python 2.1. Once we start on the 2.4 tasks, you will not be able to use a public CVS checkout of Zope with older Pythons. We are not going to start this until after Python 2.1 final is out (expected next monday), but wanted to give CVS'ers fair warning. If you are using the current public CVS and don't want to start using Python 2.1, you should either avoid doing any CVS updates until you're ready to migrate or move off of CVS to a current (2.3.1) release.

RE: [Zope-dev] **Important Notice** for Zope public CVS users
We are soon going to begin checking in changes to the head of the Zope CVS that will require the use of Python 2.1. Once we start on the 2.4 tasks, you will not be able to use a public CVS checkout of Zope with older Pythons. We are not going to start this until after Python 2.1 final is out (expected next monday), but wanted to give CVS'ers fair warning. If you are using the current public CVS and don't want to start using Python 2.1, you should either avoid doing any CVS updates until you're ready to migrate or move off of CVS to a current (2.3.1) release. will there be a 2.3 maintenance branch or will all development stop on 2.3? Sorry, I should have been more clear. There is (and will continue to be) a "current release branch", which is the branch that stable (bug-fix) releases are made from. Currently the release branch name is 'zope-2_3-branch'. This is probably the branch that most CVS users actually want to be using anyway. Running from the trunk you get all of the latest bugfixes, but you also get all of the latest half-baked work for the next feature release - which might be worse than the bugs you were trying to avoid in the first place :) So if you are running from CVS (but are not running from the current release branch) you can go into your local copy and do: 'cvs up -d -P -r zope-2_3-branch' to update to the release branch checkout. The warning is mostly aimed at the bleeding-edge people who use the CVS trunk. If you are running the release branch you will continue to get bug fixes and will not need to upgrade to Python 2.1, as the changes in preparation for 2.1 will only go into the trunk.

RackImage is a little rough around the edges, and still has some cruft left over from Photo. It is dependent on PIL, which may be unneccessary at this point.

Turns out I just had to make a few small changes in my product to get it to work, which I discovered looking at yours. Don't know if anything in my product that it would be interesting to add to yours... it's aimed at storing photos for a product catalog, most of what it adds to Image is methods for creating a photo based on another photo, used for creating a thumbnail.
