CoreSessionTracking 0.8 strangeness
by Bjorn Stabell 11 May '01

11 May '01

Hi, We're developing a shopping cart using the CoreSessionTracking product v0.8, but we've run into a strange problem; once in a while getSessionData() will create a new session data object (the token value remains the same), and us that for a while. Now we'll end up having two different shopping cart objects, with getSessionData() randomly returning one of them them. We're running Zope 2.3.1. Could it be that some threads can't find the shared session data object and creates their own? The only thing changing between each HTTP request is the thread serving the request, AFAIK. Regards, -- Bjorn Stabell <bjorn(a)exoweb.net>

Any clues as to how I trace the source of this error? I get it trying to make an xmlrpc call on my Zope server. I have other xmlrpc calls that work fine. It's not hitting my Product code, that I'm sure of... Richard -- Richard Jones richard(a)bizarsoftware.com.au Senior Software Developer, Bizar Software (www.bizarsoftware.com.au)

ZEO Clients, broken servers, and Z2.pid
by Anthony Baxter 10 May '01

As far as I can see, ZEO clients don't write a pid to Z2.pid until after they've successfully connected to a storage. Is there a reason for this? Ta, Anthony

Question about import code
by Fred Wilson Horch 10 May '01

10 May '01

Hi folks, I have hacked on the export code to allow you to export more than one object at a time. Now I'm trying to grok the import code. Can someone help me figure out what's going on? I have an export file in XML format that looks like this: <?xml version="1.0"?> <ZopeData> <record id="5602" aka="AAAAAAAAFeI="> [ first record's data here... ] </record> <record id="5603" aka="AAAAAAAAFeM="> [ second record's data here... ] </record> </ZopeData> If you export a folderish object, you'll see basically the same export format. (When you export a folder, you get all of the objects rooted in that folder.) The difference is that these two records are not related -- they are simply both contained in the same folder. The problem that happens on import is a KeyError on line 194 of this bit of code: lines 192-197 of lib/python/ZODB/ExportImport.py ooid=h[:8] if oids: oid=oids[ooid] if type(oid) is TupleType: oid=oid[0] else: oids[ooid]=return_oid=oid=new_oid() If I change this code to ooid=h[:8] if oids and oids.has_key(ooid): oid=oids[ooid] if type(oid) is TupleType: oid=oid[0] else: oids[ooid]=return_oid=oid=new_oid() then the import appears to succeed, but only the final object in the file is actually imported. I have to say that some comments would be nice in lib/python/ZODB/ExportImport.py Also, are both of these files used? lib/python/ExportImportXML.py lib/python/OFS/XMLExportImport.py Plus, I am having a hard time finding the right documentation for working directly with the ZODB to see what's going on. Can someone help point me in the right direction? Here's what I'm trying to accomplish: 1. Allow multiple objects to be exported at once (this is working) 2. Allow multiple objects to be imported at once (this is not) 3. Allow imports to overwrite existing objects (haven't tried this yet) Thanks in advance for any assistance.

PropertyManagerEvents proposal: Last call for review
by Casey Duncan 10 May '01

10 May '01

I have a proposal up for discussion on adding hookable callbacks to property events. If you are interested in such topics as property validation, CatalogAware syncing on property changes, etc, please take a look within the next few days. I think this is something that many people could use, so your comments are valued. http://dev.zope.org/Wikis/DevSite/Proposals/PropertyManagerEvents Next week I would like to deliver the patch to implement this, so if you have something to say on this topic speak now! -- | Casey Duncan | Kaivo, Inc. | cduncan(a)kaivo.com `------------------>

Object dereferancing Question
by Jeff 10 May '01

10 May '01

Hi ya'll, I have created a product with a zclass that contains a zclass; classA contains classB. Both use 'Folder' as bases class. I want the classB objects to have a 'default rendering' capability so I added a DTML Method named index_html to classB with the following code: <dtml-var expr="_.getitem(template, 1)"> Where 'template' is a property of the object that has a method name in it. So far so good, if I navigate to a classB object the correct method is called and the object is rendered. Now for the part I don't understand..... I have a page where I would like dynamically display a classB object. I used the following: <dtml-var expr="_.getitem(index_object, 1)"> Where 'index_object' is the id of a classB object within the name space (same folder). I thought that this would call the 'default rendering' for the named object, but instead returns the object. The following code worked: <dtml-with expr="_.getitem(index_object, 0)"> <dtml-var index_html> </dtml-with> Why does the "_.getitem(index_object, 1)" not return the rendered object? Thanks, Jeff

Do you have multiple acl_users objects in the acquisition context of the object? Because if you do and the self.acl_users will acquire (possibly) the wrong user database.
