OK, is the test.py in the root an artifact of make instance, or has that bug been fixed completely very recently? It's still there in Zope 2.7.3, and it was still in Zope-trunk last week. -- Lennart Regebro, Nuxeo http://www.nuxeo.com/ CPS Content Management http://www.cps-project.org/

webdav and excel read-only problem
by David King 16 Nov '04

16 Nov '04

I'm having the problem that others have already posted about [1][2]. Andreas Jung mentioned in a message from September 2004 that he had posted an explaination of the issues about two years ago. I've googled zope.org and manually searched every month in the archive at [3] and couldn't find that explaination. I've also searched through Microsoft's knowledgebase with no luck. Does anybody have a link to Andreas' message or a similar explaination of the problem?

test.py and symlinks
by Florent Guillaume 16 Nov '04

16 Nov '04

I need this patch to make test.py work when some of my directories are symlinked elsewhere. Without this, I can't run bin/zopectl test -vv --dir Products/CMFCore when Products is a symlink and CMFCore is also a symlink. I'll check it in soon unless someone sees a problem with it.

connecting server code to the ZODB
by Tim Hicks 14 Nov '04

14 Nov '04

Hi, I'm trying to figure out how to adjust Nikolay Kim's smtpserver code <http://cvs.sourceforge.net/viewcvs.py/collective/smtpserver/> so that objects within the ZODB can affect the way that messages are received (i.e. veto messages based on certain criteria in the first instance). My problem is that I don't quite know how to get hold of the ZODB objects. As far as I can tell, Nikolay's smtpserver.SMTPServer.SMTPChannel.process_message method uses ZServer.PubCore.handle to make the connection, but I don't really understand how this all works. What I really want to be able to do from the server code is something like:: root = magic_that_gets_me_zodb_root() account_manager = root['Control_Panel']['AccountManager'] account_manager.checkAccepts(msg) I want calls like that to checkAccepts(msg) to be made a several points in the SMTP session - say after each of the SMTP commands RCPT, MAIL, DATA, etc. I only mention that in case there are implications for some transaction jiggery-pokery (although I don't expect any of the checkAccepts() type calls to need to write to the ZODB). Any pointers much appreciated. tim

Need a book recommendation(s) for newer patterns and component based design
by Ira 13 Nov '04

13 Nov '04

Hi. I am new to Python, Zope, and OOP. Can you please recommend a good book(s) on patterns, component architecture, and component-based design as referred to in the excerpt from the Zope X3.0 press release below? I am reading 'Design Patterns' by Gamma, et al, but it does not include interface patterns or perhaps other, newer patterns. Thanks, Ira ------ >From the Zope 3.0 Press Release: 'Richter said the rewrite was important as Zope 2 was built primarily using object-oriented techniques such as inheritance, while Zope X3 has taken advantage of newer patterns such as interfaces and component-based design. "The main goal was to clean up the architecture," said Richter. "In Zope 2 we only used the inheritance of objects to extend and build Zope, this only takes it so far because objects become unmanageable. Zope X3 has a new component architecture that allows you to extend objects and use interfaces." '

XML Export Error and Patch
by Willi Langenberger 11 Nov '04

11 Nov '04

Hi! When i try to export a PluggableAuthService object as XML, (with ZMI Import/Export or with manage_exportObject?id=acl_users&download=1&toxml=Y) i get the following exception: Error Type: AttributeError Error Value: List instance has no attribute 'extend' [...] Traceback (innermost last): * Module ZPublisher.Publish, line 101, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 39, in call_object * Module OFS.ObjectManager, line 504, in manage_exportObject * Module OFS.XMLExportImport, line 58, in exportXML * Module OFS.XMLExportImport, line 33, in XMLrecord * Module Shared.DC.xml.ppml, line 253, in load * Module pickle, line 872, in load * Module pickle, line 1209, in load_appends Seems that the xml export calls the "extend" method of an Shared.DC.xml.ppml.List object, which isnt implemented.

Re: Zope and Python 2.4
by Alan Milligan 10 Nov '04

10 Nov '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The reason I asked this question is because clients I talk to in the enterprise space are almost all exclusively RH9/RHEL clients, and many have major reservations about installing anything non-RH 'approved' as they feel they have some security assurances using this, and certainly RH are reasonable sincere with their efforts here. If ZC say Zope is approved and test with version X of Python, then this too has some weight in their minds. We have our own distro and stability within the flux of Zope, Plone and a large number of enterprise-targeted products is probably the major sales pitch. However, having to fork off the main Fedora branch in regard to Python dependencies (which directly affect Anaconda, up2date, GTK, and most of the desktop applets) has major implications for how we maintain our distro. So, I ask again, what is the official view on Python 2.4, and if there's a roadmap as to when it will become blessed.

Zope and Python 2.4
by Alan Milligan 10 Nov '04

10 Nov '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I followed the thread a week or so ago with great interest, in that substantially Zope is working with Python 2.4 However, RedHat have now released Python 2.4 in the Fedora development stream and it will ship with FC4. Does ZC have an official position upon this yet?

Zope 3 Users Mailing List
by Stephan Richter 09 Nov '04

09 Nov '04

Hello everyone, on popular demand from a couple of people we have decided to create a new Zope 3 Users mailing list that will serve to answer your questions about Zope 3. The Zope 3 developers have made a commitment to answer your questions in a timely manner. We hope that this way the generic Zope and Zope3-Dev mailing list will be disburdened from user-related questions. You can subscribe to the mailing list at: http://mail.zope.org/mailman/listinfo/zope3-users Regards, Stephan -- Stephan Richter CBU Physics & Chemistry (B.S.) / Tufts Physics (Ph.D. student) Web2k - Web Software Design, Development and Training
