Attribute lookup
by Gabriel Genellina 04 Nov '03

04 Nov '03

Hello I have a class A, and another class B which is a wrapper for it (a Product, inherited from SimpleItem.SimpleItem). I want B to delegate most attributes to A: class A: def __init__(self, title, ...): self.title = title .... class B(SimpleItem.SimpleItem): def __init__(self, id, title): self.id = id self.innerA = A(title) def __getattr__(self, name): return getattr(self.__dict__['innerA'], name) This works fine for most attributes *but* title. SimpleItem.Item has a class attribute 'title' and, altough B instances have no 'title' attribute at all, they inherit an empty class attribute 'title' from Item, and never goes thru __getattr__. How could I arrange things so 'title' comes from inner A instance, and *not* from Item base class? Gabriel Genellina Softlab SRL

strange zope behavoir: zope not responding
by Matthew Thorley 04 Nov '03

04 Nov '03

I have observed some strange behavior from two of my zope servers (ver 2.6.2) that I am unable to find a cause for. FYI both servers are running on intel boxes under redhat 9.0. Case one; When I start the server in debug mode everything appears to be fine. When I went to the servers url on port 8080 I see the default indexpage. When I click the link for the management section I get a dialog to log in. After entering the correct user and pass my browser attempts to load the management section and hangs. Generall it builds the frames for the page and loads the data for the header frame and the text for the left (navigational frame) but only empty (image-not-loaded-yet-icon) boxes where the images should be and I can see nothing in the main page frame. If I restart the server the same thing happens. I also tried starting the server with these options -a ipaddress -Z1 -t 10 -f - -w - . After the page hangs it won't load(server?) the index page any more or any other page. My browser just sits there doing nothing until it times out with 'document contained not data' Case two After I start my server (different server then case 1) everything is fine and dandy for some time. I can create object, test objects and do normal zope stuff. At some point thought the server hangs, meaning any page I visit refuses to load and eventualy times out. At this point I can't even reload the page for objects that I am currently working on. The only thing that I remedies this is to restart zope. Another thing that I have observed is that generaly speaking when the server gets to this stage, if I press ctrl+c to kill the server (in the window where it shows that it is running) It doesn't actualy kill the server. I don't get the messages: 2003-10-31T00:50:45 INFO(0) Z2 Closing all open ZODB databases ------ 2003-10-31T00:50:45 INFO(0) Z2 Shutting down It just dies silently. But if I run ps aux | grep Zope it shows a Zope process running. Does any one have any idea why this is happening ? or have you ever experienced this yourself? thanks very much -matthew

Hi, has anyone ever had problems when submititng large pdf files to the Zope DocumentLibrary. I've got three pdf files to submit.. two of them are about 400K while the last is nearly 3M. The first two are loaded ok wheras I get an error when trying to submit the last large file... Is there anything I can do about this or do I simply have to resign myself to the fact that largish files are not supported? Cheers Ruth

problems with plone
by Robert Chares 04 Nov '03

04 Nov '03

Hello, I am trying to get started with Zope and Plone. Zope basically works fine, but after trying to install Plone, I get a startup exception. The OS I am working with is SuSE 8.2, the Python version I compiled Zope with is 2.1.3 and the Plone version I tried is 1.0.5. When I follow the install instructions of Plone I get the startup exception of Zope telling me that it can't import the TRIGGER_USER_ACTION (detailed error messages at the end of the mail..) After removing the link to the CMFPlone directory, everything works again fine... Can you tell me what I did wrong or give me a hint what I should try to change, because I haven't found any help in forums or faq's. That's why I have to bother you ;-) thanks and bye Robert robert@nihilbaxter:~/zope/Zope-2.6.2-src> ./start ------ 2003-11-02T21:11:23 INFO(0) zdaemon Started subprocess: pid 19410 ------ 2003-11-02T21:11:25 ERROR(200) Zope Could not import Products.CMFPlone Traceback (innermost last): File /home/robert/zope/Zope-2.6.2-src/lib/python/OFS/Application.py, line 522, in import_product File /home/robert/zope/Zope-2.6.2-src/Products/CMFPlone/__init__.py, line 6, in ?
