[ANN] TextIndexNG 3.0.8 released
by Andreas Jung 29 Oct '05

29 Oct '05

I am pleased to announce the release of TextIndexNG V 3.0.8. TextIndexNG V 3 is a complete new implementation based on Zope 3 technologies and can be used both in Zope 2.8 or 2.7 (with Five) or in Zope 3. What's new? - multi-field indexing and query support - multi-lingual support - configurable converters (through ZCML) - new indexing API (allowing you to hook your custom content types with TextIndexNG through Zope 3 adapters). Changes since V 3.0.8: - reorganized extension modules. They are now stored under the hierarchy 'zopyx.txng3'. For this reason **you need to recompile and reinstall all extension modules**. - optimized storage.insertDocument() to play more friendly with the ZODB (smaller transaction sizes). - Fixed a weird Python 2.4 incompatibility in the parser code: subclassing the EnglishParser resultet in unpredictable and non-deterministic errors! Requirements: - Zope 2.8 or Zope 2.7 (+ Five) or Zope 3 (Zope 3 has nothing like catalogs yet) TextIndexNG V3 will *not* run with bare Zope 2.7 installations without Five (and this will not be changed in the future). Download: http://sf.net/projects/textindexng Project page: http://opensource.zopyx.biz/OpenSource/TextIndexNG3 For installation and documentation issues refer to doc/README.txt from the archive. It's basically the same procedure as with former versions except you *need* to recompile the extension modules. Windows binaries of the required extension modules are currently not available (any volunteers?). TextIndexNG V 3 is published under the ZPL.

Re: [Zope] How do I Create a empty file in a ZClass object?
by Jonathan Cyr 28 Oct '05

28 Oct '05

That seems to be the problem, I find ZClasses to fill a role for intermediate skill level developers to create rich objects and applications. The replacement at this difficulty level hasn't appeared yet. My impression is that ZClasses will continue in Zope 2.x, but it hasn't been enhanced or touched at all. The ZClasses implementation seems to be solid. There are shortcomings with ZClasses when you try to do too much with them. Some of the Zope 2 books have nice examples are how and what you can do with ZClasses. That said, I picked up Stephen Richter's book on Zope 3, very nicely done... Zope 3 seems to be maturing pretty fast, and some/most of the new features have been adapted to the older Zope 2 architecture (a project called Five). If you're going to make a large investment in time... and you're just getting started, I'd pick up this book, and see if you can handle the difficulty level of Zope 3, at this point. Zope 3 technologies seem to be "the New Way". Although advanced, Zope 3 seems to be the result of a lot of self-examination of the triumphs and mistakes of Zope 2... a few things I picked out.... an re-thought organization scheme of naming, libraries, etc., the use of interfaces/contracts.... Generally cleaner and more pythonic, allowing much more power and flexibility... removing much of the mystery of Zope 2 inner workings and naming conventions. As for DTML, the old way, DTML is a tag-based way to create web interfaces, similar to CFML, PHP, ASP... inline tagging around and within the HTML. The new way, is markedly different, and difficult to get your head around at first, called ZPT (Zope Page Templates). ZPT uses XML and an attribute system to embed commands in an HTML page, without ruining your ability to use WYSIWYG editors like Dreamweaver, etc. ZPT is highly regarded here on this list, and probably will win out in the end. But there are enough DMTL folks, that DTML will be in Zope 3 until ZPT takes over. There is a Zope 3 mailing list, that might be helpful.

Problem after upgrade zope from 2.6.0 -> 2.8.4
by Zhi-Wei Lu 28 Oct '05

28 Oct '05

Hi Zope Gurus, After I upgraded the zope from 2.6.0 -> 2.8.4 on a Redhat EL3 server, with python 2.4.2 (and I also tested with python 2.3.5), the gif pictures are now slightly misaligned a little bit, these graphics are in a TABLE with BORDER=0, CELLPADDING=0, and CELLSPACING=0. The graphics looked fine with Zope 2.6.0. Does anyone see similar behavior with Zope 2.8.4? Thank you for help.

by Krzysztof Kubacki 28 Oct '05

28 Oct '05

I have LDAP database installed on Debian and 2 Zope-platforms: Zope 2.7.6, Plone 2.0.5 GRUF<3 Zope 2.8.4, Plone 2.1 GRUF 3.4 GRUF stands for GroupUserFolder I have installed LDAPUserFolder on both Zope-platforms. I store user in LDAP insted of UserFolder everything works fine beside that I can't list members by mean of functions which come from portal_membership object. for instance the codes below won't work. users = context.portal_membership.searchForMembers() return users or users = context.portal_membership.listMembers() return users I have user in LDAP named 'krzysztof' the code below works user = context.portal_membership.getMemberByID('krzysztof') return user I'm a bit dogged becouse I don't want to recode my exists scripts and use other functions(for instance from LDAPUserFolder) to list my members. Has somebody the same situation or know what is the reason of that? Regards Krzysztof Pozdrawiam Krzysztof Kubacki (56) 658-95-44 BusinessMedia Professional Group

Zope 2.7.7 and Python 2.4.0
by Shane Graber 28 Oct '05

28 Oct '05

I just updated my Zope 2.7.5 instance on Ubuntu/breezy to Zope 2.7.7. While I was running Zope 2.7.5, Python 2.3.5 was the version that was specified and shown in the ZMI. After upgrading from Ubuntu/hoary to Ubuntu/breezy two nights ago, my versions are now Zope 2.7.7 and Python 2.4.0. I understand that Python 2.4.x is not supported/recommended in Zope 2.7.7, so how does one specify an older version of python? I'm still learning Linux so any help would be appreciated. Thanks in advance, Shane -- http://liquid.homelinux.org/

Zope 2.8.4 released
by Andreas Jung 28 Oct '05

28 Oct '05

Hi all, on behalf of Zope Corporation and the Zope community I am pleased to announce the release of Zope 2.8.4. You can download Zope 2.8.2 from http://www.zope.org/Products/Zope/2.8.4/ This version obsoletes Zope 2.8.2 and Zope 2.8.3 which shipped with an older Docutils version as expected. For security reasons you should update to Zope 2.8.4. In addition this release fixes a potential security problem when using Zope with Python 2.4 - although Python 2.4. is neither recommended nor supported. This release does *not mean* that Python 2.4 is from now on supported but there are already installation using Python 2.4 (mostly because modern Linux distributions ship with Python 2.4 and Zope usually uses the system-widePython installation). 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/2.8.3/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 2.8.4 requires Python 2.3.5. Zope 2.8.4 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)

Debugging security settings in .metadata files
by Floyd May 28 Oct '05

28 Oct '05

I have a set of files - page templates, python scripts, and zsql methods - that are set up as filesystem objects. I'm having trouble getting the security set the way I want it to be with the .metadata files. Here is the content of my .metadata files: --------------8<------------------------- [security] View = 0:Manager Access contents information = 0:Manager Access Contents Cnformation = 0:Manager -------------8<-------------------------- However, I can still access my content through an anonymous context. Can anyone give me some ideas about debugging my situation? Thanks! Zope 2.7.7-final, python 2.3.5, freebsd5 CMF 1.4.8 fm

help - my zope build exits with compile errors :-(
by Thomas Wolf 27 Oct '05

27 Oct '05

Hi, I'm trying to build Zope-2.7.4-0 from source (I can't use a different version because of the releas of Plone we're using.) I ran ./configure --with-python=/usr/local/zope/python/bin/python --prefix=/usr/local/zope" and that reported no issues. BTW, I'm using python 2.3.5 - that's why I had to use the --use-python argument. Then I ran make. No reported problems for quite a bit into the build - then I get: gcc -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -fPIC -I/usr/local/zope/python/include/python2.3 -c Products/PluginIndexes/TextIndex/Splitter/ISO_8859_1_Splitter/src/ISO_8859_1_Splitter.c -o /usr/local/zope/Zope-2.7.4-0/build-base/python-2.3/build-temp/Products/PluginIndexes/TextIndex/Splitter/ISO_8859_1_Splitter/src/ISO_8859_1_Splitter.o gcc: Products/PluginIndexes/TextIndex/Splitter/ISO_8859_1_Splitter/src/ISO_8859_1_Splitter.c: No such file or directory gcc: no input files Sure enough, there's no ISO_8859_1_Splitter.c file - but I haven't got a clue why not. IS this generated by an earlier part of the build and just didn't? Or was there something missing from the tar ball (I got it off www.zope.org!) Any help/suggestion would be much appreciated, Tom P.S. I'm trying to build this under Solaris 9 using gcc 3.3.2.
