constructor product in Zope 2.8.1
by Henny van der Linde 13 Oct '05

13 Oct '05

Hi, I have the following constructor for an external product I build. def manage_addEba(dispatcher, id='eba', title='Title here',REQUEST=None): "Add a Basis element to a folder." nEba=eba(id,title) dispatcher.Destination()._setObject(id, nEba) if REQUEST is not None: dispatcher.manage_main(dispatcher,REQUEST) manage_addEbaForm = DTMLFile('dtml/manage_addEbaForm', globals()) We are upgrading to Zope 2.8.1. Now I get the follwing error when I try to add the product (eba). Error Type: TypeError Error Value: unbound method manage_addEba() must be called with eba instance as first argument (got str instance instead) Can anyone shed some some light on this? Thanks, Henny

External Methods
by DS 13 Oct '05

13 Oct '05

Hi, I am just learning Zope, and I wanted to try external methods. I first tried a symlink in the Extension directory, but zope reported it couldn't find it. I then copied the file into the Extension directory and was successful at that. I assume that happened that way perhaps for my own protection. Is that true? Or, is there a better way to do that? I have a project directory where I have been working on modules, and I was hoping to avoid copying them periodically to Extensions as I test one thing or another. My next question is that I import other modules within the module that I just mentioned. I have copied them over to Extension, but still have an error that they are not found. Am I trying to do something prohibited with Zope. What controls that? Thanks very much for any help you can give me. ds

But I'm leaving the trunk alone, as it looks like lots of stuff from 2.8 is not yet in the trunk CHANGES.txt, and I don't want to confuse things further - AFAICT the normal procedure is to let the release manager handle the merging of bugfixes in CHANGES.txt. Thanks again Andreas and anybody else who worked on the release, -PW -- Paul Winkler http://www.slinkp.com

Zope 2.8.2 released
by Andreas Jung 13 Oct '05

13 Oct '05

Hi all, on behalf of Zope Corporation and the Zope community I am pleased to announce the release of Zope 2.8.2. You can download Zope 2.8.2 from http://www.zope.org/Products/Zope/2.8.2/ Some new features of Zope 2.8: - ZODB 3.4 with MVCC (multi version concurrency control) support. MVCC solves nearly every problem with ZODB read-conflict errors which is very important for high-traffic Zope sites. - Extension Classes were rewritten as Python new-style classes making all features of Python new-style classes available in Zope objects. This includes support for cyclic garbage collection. - Integration of Zope 3 technologies through Five (see http://codespeak.net/z3/five/) For more information on what is new in this release, see the CHANGES.txt files for the release: http://www.zope.org/Products/Zope/2.8.2/CHANGES.txt See also: http://www.zope.org/Wikis/DevSite/Projects/Zope2.8/OverView Please bring all the bugs you have found to the Zope bugtracker: http://collector.zope.org/Zope":http://collector.zope.org/Zope For more information on the available Zope releases, guidance for selecting the right distribution and installation instructions, please see: http://www.plope.com/Books/2_7Edition/InstallingZope.stx Please also keep in mind that Zope 2.8.2 requires Python 2.3.5. Zope 2.8.2 is not certified for any Python 2.4.x versions. So using Python 2.4 is neither recommended nor supported and any related questions or problems are likely to be ignored until 2.4 is an officially supported Python version for Zope. -- Andreas Jung (andreas at zopyx dot com)

Yep, that's what zdb does.. > By unpluggable do you mean it assumes code is on the file system? Yeah, and it certainly was a fair assumption, but what with now having code coming form .zip's in plain python and zodb in Zope, it reallt could do with a good kicking... > Yes, you don't want the debugger on a production system. Simply setting > the co_filename attribute won't slow the system down, though. Yup, but zdb pre-stuff the linecache so the normal pdb mechanisms can find the code, and that _is_ expensive ;-) Not to mention oh so many monkey patches calls which both zbd and WingDbg suffer from ;-) cheers, Chris - who would be interested to know if you actually downloaded zdb and had a look at its source... -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
