Bravery & Zope 2.5 Testers
by Matthew T. Kromer 16 Jan '02

16 Jan '02

OK, I am formulating a hypothesis that if you replace ExtensionClass.h in Zope 2.4 and Zope 2.5 with the following one: http://cvs.zope.org/~checkout~/Zope/lib/Components/ExtensionClass/src/Exten… (Which goes in lib/Components/ExtensionClass/src/ExtensionClass.h btw) and rebuild zope .... python2.1 wo_pcgi.py and rebuld any other modules you may have which depend on extension class that some of the segfaults could go away. I have one person testing this right now, and am looking for others to prove it. I have *not* been able to reproduce any crashing problems (even Martijn Faassens one) so I can't tell what may be going wrong for sure.

One object where there should be two
by Adrian Hungate 16 Jan '02

16 Jan '02

I am having a problem with XMLKit. I have the following code in which should use one disk based DTML Method and produce two slightly different creation forms, one for XML and one for RSS (a specialization of the XML form):- manage_addRSSDocumentForm = Globals.DTMLFile('www/addXMLDocument', globals(), kind='RSS') manage_addXMLDocumentForm = Globals.DTMLFile('www/addXMLDocument', globals(), kind='XML') The problem is that both of my constructors run the RSS form, the XML version never gets displayed. I have checked the code in __init__ and it appears fine:- context.registerClass( XMLDocument.XMLDocument, meta_type='XML Document', permission='Add XML Documents', icon='www/XMLDocument.gif', constructors=( XMLDocument.manage_addXMLDocumentForm, XMLDocument.manage_addXMLDocument, ), ) context.registerClass( XMLDocument.RSSDocument, meta_type='RSS Document', permission='Add RSS Documents', icon='www/RSSDocument.gif', constructors=( XMLDocument.manage_addRSSDocumentForm, XMLDocument.manage_addRSSDocument, ), ) I've tried just about everything I can think of, can anyone shed any light? Is this a special rule I have broken? Thanks. Adrian... -- Adrian Hungate All views expressed in this email are those of the whole world, however some people don't realise this yet.

Using Queue within a Zope product
by Max Slimmer 16 Jan '02

16 Jan '02

I need to put messages into a queue from within a Zclass, and then get and process them from an external long running process. I have created a class which imports a derivative of queue, the class instantiates a queue as a class object. The idea is that the queue will use a persistent object for the queue (list), and then some external process can also use the same object(list) in its queue processing. Both the zclasses that inherit from this queue and the external process must use the same mutexes... Questions: 1 Should the queue.queue object be made persistent or should we instantiate it with an external list which is the persistent object. Can either of these be done an how. 2. Assuming we can do something like the above what are the considerations wrt package distribution.

Accessing objects starting with _
by Adrian Hungate 15 Jan '02

15 Jan '02

I know that Zope uses the fact that an object or method starts with _ as a security feature, but is there a way of circumventing it? I am looking at the posibility of developing a basic level of Microsoft Frontpage support, but ALL frontpage actions contain _ in the folder names. If there is just one point in the code that I need to add a few exceptions to the "Can't start with _" rule, then I can do that - This project is fairly important.

Utility of zope.org wiki page subscriptions
by Ken Manheimer 15 Jan '02

15 Jan '02

I'm finding the wiki page notifications mechanism extremely helpful for tracking wiki activity. While there's not much time available to tweak it further for people's needs, i'd like to collect feedback about how it does and doesn't serve other people's purposes, so that when we get around to the comprehensive effort we'll be able to factor-in that info! If you're using the feature and have comments, or not using the feature because of some shortcoming, please take a moment and add your comments to the effort feedback page: http://dev.zope.org/Wikis/DevSite/Projects/FishbowlNotificationsForNow/Feed… If you're not using the feature because you don't know about it (what the heck am i talking about, anyway?-), see a copy of the announcement at: http://dev.zope.org/Wikis/DevSite/Projects/FishbowlNotificationsForNow/Rele… (For those of you that missed that announcement and the "subscriptions" links, i think the feature is quite useful as is, and can significantly enhance the fishbowl process if it's used.) -- Ken klm(a)zope.com

Whew, at long last, I've posted a Sprint Schedule at: http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/SprintSche… Boy, that URL is too long.

CMF attribute horror or too many [t|T]itles
by Romain Slootmaekers 15 Jan '02

15 Jan '02

Yo dudes, just a stupid simple question: After wrestling with the documentation, I have created my own CMF content type and it actually works except for some details. In retrospect, it was 90% code browsing, and 10% useful documentation,... cmf is fun, but the cmf dogbowl really sucks .. Anyway, The type I created has a method def Title(self,REQUEST=None): ... and that gets used by some of the skins, The meta data of the object also has an attribute Title, which is used by the Topics for indexing, Now my problem: when a topic lists one of my objects, it lists them with ... <li> <a href="&dtml-objURL;"><dtml-var Title>.</a> </li> ... but neither my Title() method nor the Meta-data's Title attribute gets to be used. I get an empty string. Where does that one come from ? To make it even more confusing, the object also acquires a title attribute from somewhere higher up the acquisition tree. PS: I noticed the same problem when adding fi a File object through the zope management api instead of the portal management interface. Anyone any clues ? TIA, Sloot.
