by Andreas Jung 24 Apr '05

24 Apr '05

Dear Zope Community, on behalf of Zope Corporation and all Zope 2 developers and contributors I am pleased to announce the release of Zope 2.8.0 b1. Zope 2.8.0 b1 can be downloaded from http://www.zope.org/Products/Zope/2.8.0b1 The release notes can be found at http://www.zope.org/Products/Zope/2.8.0b1/CHANGES.txt For information on using Python 2.4 with Zope 2.8: see doc/INSTALL.txt Every developer is strongly encouraged to test Zope 2.8 beta 1 *now* and not to wait until the final Zope 2.8 release...that's why we have beta releases :-) The quality and stability of the final release depends on *your* testing *now*. This release is a major step towards Zope 2.8.0 final (scheduled for the 3rd week of May 2005) and now includes for the first time the "Five" framework to make some Zope 3 technologies available within Zope 2. So you will be able to use Z3 technologies like interfaces, adapters, schemas and views within your Zope 2 installation and have hopefully the best from the Zope 2 and the Zope 3 world.

Strange lockup during functional tests (sandboxed)
by Balazs Ree 23 Apr '05

23 Apr '05

Hi, I'm running Zope 2.7.5-1, python 2.3.5-2 and experience that during the runnig of my own functional tests (sandboxed) after a few tests the program locks up (CTRL-C does not work, CTRL-Z yes). I can reproduce the issue with the following test: --- from Testing import ZopeTestCase ZopeTestCase.utils.setupCoreSessions(ZopeTestCase.Zope.app()) class TestSessionBug(ZopeTestCase.Functional, ZopeTestCase.ZopeTestCase): ''' This locks up in the start of test07! The checkpoint is never reached. ''' def afterSetUp(self): print 'Checkpoint' request = self.app.REQUEST sdm = self.app.session_data_manager request.set('SESSION', sdm.getSessionData()) self.sessipn = request.SESSION def test_01(self): pass def test_02(self): pass def test_03(self): pass def test_04(self): pass def test_05(self): pass def test_06(self): pass def test_07(self): pass def test_08(self): pass def test_09(self): pass def test_10(self): pass def test_11(self): pass def test_suite(): from unittest import TestSuite, makeSuite suite = TestSuite() suite.addTest(makeSuite(TestSessionBug)) return suite -- The setup of the sessions in the above code triggers the problem but it might not be its direct reason. Even without this it happens in some of my test methods. The lockup is very deterministic and it does not seem to have much to do with the test methods themselves, that is, if I just run the test method where it broke, it does not occur. What am I missing? Can someone reproduce this? -- Balazs REE

batch processing with CMFPhotoAlbum
by Malthe Borch 22 Apr '05

22 Apr '05

Hello list, --- In the sake of usability, I'd like to offer my users the ability to upload a compressed archive (i.e. zip og tarball) of photos, so that uploading a roll of film isn't a days work, but rather two or three clicks. Obviously, there still would be a need to do a group-rename afterwards, but the idea is pretty solid I think. I'll want to use the standard way of adding a photo, only also allow for archives in the submission process. Would anyone care to collaborate or share ideas on such a patch? I assume it would be useful with other media as well. \malthe

Adding Carriage return/line feed to a text field

Are there arguments or a > script that will add carriage return/line feed after you set the parameters? You can wrap it in HTML <pre> tags. This preserves formatting on layout. Otherwise, you'll have to replace the newlines in your text with <br/> tags. Products.PythonScripts.standard.newline_to_br will do this for you, as will the newline_to_br attribute on the dtml-var tag. (You can find this in the Zope online help.) --jcc Thanks for the help, it seems my company blocks lists so I did not get your response until this morning when I checked the archives.

Question regarding changing Zope site to another distro
by Mário Gamito 22 Apr '05

22 Apr '05

Hi, I run this Zope/Plone site - www.dte.ua.pt I am no Zope guru. I've just managed, with my years on administrating Linux servers, to install it, as well as plone and a bunch of Products, and get it running. That's all. Just made after, a few hacks in Plone code, mainly to support authentication through HTTPS and a few more minor thingies. The server running Zope has been there for about three years (more or less), is running SuSE 9.0 and it was compiled as well as Pyhton. The latest versions of Zope and Python, were by that time 2.6.1 and 2.1.3 respectively. So, to live on the edge, i've instaled this versions under: /usr/local/zope and /usr/local/python I start zope with: /usr/local/zope/start & and in /usr/local/zope/start file, i have exec /usr/local/python/bin/python $cwd/z2.py -L 'pt_PT' -u zope "$@" I'm moving this machine to a more powerful one in which i'm going to install Red Hat Enterprise Linux 4. I remeber having installed it first in RedHat 9, and then switching it after a few days to SuSE 9.0, just by backing up /usr/local/zope directory and restoring it after in SuSE. No major issues with this. A couple of symbolic links did to tweaks that were needed. Now... I think my Zope is suffering from arthritis :( I can't undo any more, either in Zope nor Plone and i can't compress Zope's database without getting an error and... no database compressed. As if you care to rapidly browse the site, you will see it is indeed a small one, but the /usr/local/zope .bz2 tarball is already at 1 GB and increasing. Does this sympthoms means that i'm going to have troubles now migrating to RHEL 4 ? Maintaining the Zope and Python version of course and the same scheme. I don't want to upgrade Zope, nor Python, nor Plone. Any help would be apreciated.

Newbie - Cannot cut and paste objects in ZMI
by Dustin Freeman 22 Apr '05

22 Apr '05

Hello all, Just got Zope 2.7.5 up and running on my Win2003 server with IIS. Was working my way through the Book and the "Elvis" tutorial and I cannot cut/copy objects and paste them in to other folders though the ZMI. I'll check the object click cut...toolbar changes to display the paste button but then I click to the object (folder) I want to move it to and bam Paste button goes away... I have not found any information if Zope will work with my config but it seemed to be working until this issue.... Again I am very green...reasonably familiar with windows and IIS but Zope is a whole new ballgame. Thanks for any help or info that would make my Zope experience a good one!

Product data acquisition by <dtml-var>
by Anders Karlsson 22 Apr '05

22 Apr '05

I am working some on a product where I have some problems making a nice interface to the calling dtml-code. My product grabs and caches RSS data for a feed, and now I would like to make an interface much like the one that is provided by the "Z SQL Method". My problem is that I can't find any documentation or examples of how to make this work with the acquisition. I would like to be able to do something like this to show the results of the object my_feed: <dtml-in my_feed> <dtml-var title><br> <dtml-var date><br> <dtml-var description><br> <hr> </dtml-in> I have found out that I in my product class can have a __len__() function that returns the result size and a __getitem__() function that returns a numbered element. If I return a mapping from that function I can access the resulting values as I want, but to make it work I need to add the "mapping" attribute to my <dtml-in>-tag. I would like to get the same result without having to tell dtml-in that it's a mapping, just like "Z SQL Method" does. I have tried to understand the "Z SQL Method" code, and I see that it returns objects of a result class from the __getitem__() function. Is there any specifications telling which functions such a class needs to implement? I have tried doing such a result class, but when I execute the code I get: Error Value: unbound Python method must be called with RSSItem 1st argument Can anyone please point me to some documentation or in any other way enlighten me?

Adding Carriage return/line feed to a text field
by MCDONNELL, LARRY 22 Apr '05

22 Apr '05

Hi, I have a form that the field length for that element is set to 65k in the database. Using a textbox, the person can enter their information. I now want to view the text. I can again use a text box but what I want to do is this - <dtml-var mytext> If I use this format, the text is one line. Are there arguments or a script that will add carriage return/line feed after you set the parameters?
