Using Python script to create ZClass instances
by Bjorn Stabell 12 Apr '01

12 Apr '01

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, -- Bjorn Stabell <bjorn(a)exoweb.net>

[ANNOUNCE] Zope Developer's Guide Preview
by Amos Latteier 11 Apr '01

11 Apr '01

Fellow Zopistas, I'm proud to announce the first preview release of the Zope Developer's Guide. http://www.zope.org/Documentation/ZDG The ZDG picks up where the Zope Book leaves off. Its main focus is teaching you how to develop Zope products. We've finished rough drafts for five of the six planned chapters. There are still lots of mistakes and omissions not to mentions countless typos. However, there is a lot of technical information there and most of it is accurate and up to date. If you would like to be involved in the project take a look at the project area http://www.zope.org/DocProjects/DevGuide You'll find information on CVS access, background information on the project and links for submitting bug reports. Let us know what you think! I recommend submitting bug reports with comments and suggestions (that way it's harder for us to loose your comments.) http://sourceforge.net/tracker/?group_id=22339&atid=375126 Enjoy! -Amos -- Amos Latteier mailto:amos@digicool.com Digital Creations http://www.digicool.com

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. Unless great care is taken, DOM tree can be highly cyclic and would therefore not be garbage collectable by Pythons 1.5.2 reference counting garbage collector. Dieter

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. -- Karl Anderson karl(a)digicool.com

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. I'd like to make sure that the ref really is going away, though :) > a quick browse through the source of ParsedXML doesn't offer any clues on how > to release the object (or if its nescessary). its hard to say since > acquisition is being used to help with the dom tree. Acquisition is what we're currently using to avoid circular references. -- Karl Anderson karl(a)digicool.com

Does anyone have advice for tracking (apparent) memory leaks other than sitting watching DebugInfo? Cheers. -- Andy McKay.

PLEASE trim cited text!
by Ken Manheimer 11 Apr '01

11 Apr '01

I've been watching this for a few days now, holding back, but it's **awful**! *Please* take a few moments to extract relevant portions from cited text, definitely do *not* include the whole thing! (There is no excuse for multiple copies of the footer, usually not an excuse for a single copy.) For those of us that read via digest mode, at least in some interfaces, it makes increasingly hard to find messages. I'm taking the liberty to include one example just to demonstrate the ridiculous length this has gone.

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. - mn > > ----- Original Message ----- > From: "Marco Nova" <nova(a)tera-it.com> > To: "Zope-Dev (E-mail)" <zope-dev(a)zope.org> > Sent: Wednesday, April 11, 2001 2:29 AM > Subject: RE: [Zope-dev] memory leak > > > > > have you checked the debug page in the control panel and > > > noted any refcounts > > > increasing? > > > > Class April 10, 2001 9:17 am April 11, 2001 8:34 am > > > > Products.ParsedXML.DOM.Core.Text 3241 > 27318 +24077 > > Products.ParsedXML.DOM.Core.Element 1777 > 14493 +12716 > > Products.ParsedXML.DOM.ExpatBuilder.ExpatBuilder 81 1506 +1425 > > Products.ParsedXML.Printer.PrintVisitor 3 107 +104 > > Products.ParsedXML.DOM.Core.Document 10 112 +102 > > > > Yes, I've a lot of refcounts leaks. > > > > > any chance that this is the same problem that andy is running > > > into (read his > > > posts above)? > > > > I dunno because of my very lack of knowledge of Zope. > > All of these refcounts leaks means that the Product is > doing something > wrong > > or that I'm using in the wrong manner ? > > > > - mn > > > > > > > > -d > > > > > > On Tue, Apr 10, 2001 at 05:27:28PM +0200, Marco Nova wrote: > > > > 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.
