(I copied a traceback snippet below for reference). I can still copy and paste a ZClass Instance, then delete the original instance. As for renaming, I can rename the instances OK. Can you see the IDs of your instances? If you cannot see the ID values on the property pages and cannot access them from DTML take a look at this draft document: <http://www.zope.org/Members/AlexR/ZClassIDBug>. It might help. Cheers.

Can't get rid of ZGadfly in Add menu
by Itamar Shtull-Trauring 27 Oct '99

27 Oct '99

I have a ObjectManager/ZCatalog ZClass Searcher which can contain folders. I create a folder Test in an instance. / -> Searcherinstance -> Test Both Test, Searcherinstance, and the root folder do not let Owners add ZGadfly objects, yet it shows up in the add menu of Test as an option for a Owner to add. Apparently the Searcher ZClass inherited the ZGadfly permission from either the FOlder or ZCatalog, I can't figure out why they're a default in either, but I still have set it to not allow it to Owners.

You cannot sort on a text index, only a field index. Is this what your doing? Also, when reporting an error, the traceback is very useful. Otherwise I'm just guessing. -Michel

FYI: Zope Weekly News
by Amos Latteier 27 Oct '99

27 Oct '99

Hi, As usual, the vast quantity of Zope activity this week is a bit overwhelming. One notable trend is the blossoming of not only community contributed Zope software, but community contributed Zope documentation. For example, there are currently 75 How-Tos on Zope.org! In addition, this week also saw several announcements for documentation on writing Python Products. * Jon Udell wrote an article entitled "XML-RPC Programming with Zope" for Zope for byte.com. http://www.byte.com/column/BYT19991021S0014 * Python God Andrew M. Kuchling started a discussion about implementing XML-RPC Methods for Zope. http://www.zope.org/pipermail/zope-dev/1999-October/001949.html * O'Reilly Editor-in-Chief Frank Willison announced that he has nothing to say about any rumored Zope book ;-) http://www.oreilly.com/frank/ * Butch Landingin released Squishdot 0.3.2 which is a bugfix release. http://squishdot.org/Download/Squishdot * Scott Roberts announced preliminary support for FastCGI. This package extends ZServer to allow it to speak to web servers that support FastCGI. This is similar to PCGI but more efficient. http://www.zope.org/Members/sroberts/fastcgi-support * Ross Lazarus announced an updated LDAP adapter Product. It acts like an acl_users folder but allows authentication from an LDAP server. http://www.zope.org/pipermail/zope/1999-October/012662.html * Anthony Baxter released SQL Session v.0.1.1 which provides persistent session objects which are stored in a SQL database. http://www.zope.org/Members/anthony/software/SQLSession http://www.zope.org/pipermail/zope/1999-October/012642.html * Ken Manheimer announced a How-To entitled "Debugging Zope Python Code" which, while incomplete, is full of juicy tips for Zope hackers. http://www.zope.org/Members/klm/debuggingzope * Garth Kidd released a How-To and an example Zope Product which illustrates extending Zope in Python. http://www.zope.org/Members/gtk/Boring/HowTo-Boring * Speaking of examples of Zope Products in Python, Jeff Rush also posted an example Python Product. http://starship.python.net/crew/jrush/Zope/ * Rounding out this week's Python Product announcements, Amos Latteier will give a talk on "Extending Zope in Python" at the Portland, Oregon Python Interest Group (PORPIGgies) meeting on November 1. http://www.egroups.com/group/porpig/4.html * Jonothan Farr released a Local File System Product. This allows you to create objects which provide controlled access to the local filesystem http://www.zope.org/Members/jfarr/LocalFS * Alexandre Ratti wrote a How-To which describes custom date formats. http://www.zope.org/Members/AlexR/CustomDateFormats * Michel Pelletier announced a preliminary Portal Tool Kit model on the zope-dev list. The PTK may not be complete vaporware after all ;-) http://www.zope.org/pipermail/zope-dev/1999-October/001908.html * Oleg Broytmann posted a patch to load_site.py which allows you to create more Zopish DTML Documents from imported HTML files. http://www.zope.org/pipermail/zope-dev/1999-October/001935.html * A.M. Kuchling released ODP 0.03 This is a Zope product which allows browsing of the Open Directory Project's RDF dumps. The ODP is the information which powers the search engine at http://dmoz.org/ http://starship.python.net/crew/amk/zope/ODP.html http://www.zope.org/pipermail/zope/1999-October/012622.html * Tim Wilson started a discussion of Zope and RDF which soon expanded to include syndication and RSS. http://www.zope.org/pipermail/zope/1999-October/012721.html * Despite the Perl conspiracy ;-) Zope showed up on several times and in a positive light on another Slashdot thread. http://slashdot.org/askslashdot/99/10/16/166256.shtml * Amos Latteier posted to the ZDP list concerning a possible future turning over of the Zope Guides to the Zope community. http://www.zope.org/pipermail/zdp/1999-October/000919.html Until next week. -Amos -- Amos Latteier mailto:amos@digicool.com Digital Creations http://www.digicool.com

I just added Mr. Creosote to my DA to log all of the queries via UDP to a loghost, with timestamps - this makes it easy to view the queries as they happen even on another machine, you can also take a log if you want. Crude, but it's not bad. Mr. Creosote is in the pcgi/ directory of your Zope installation... --Brian

Re: [Zope] RH 6.1 Startup error
by Karl Anderson 27 Oct '99

27 Oct '99

I'll confirm that a vanilla RedHat 6.1 dist. with the Zope/zserver 2.0.1-4 RPMs doesn't work. This is bothersome because 6.1 (or maybe 6.0) is the only RedHat dist. that comes with a recent enough Python. I think that this is because the system logger isn't listening to a port by default. I changed /etc/rc.d/init.d/syslog.d to do this by default (with -r) & then restarted it. For the paranoid, this is yet another port being listened to, with DoS vulnerabilities mentioned in the man page. 24,25c24 < # daemon syslogd -m 0 < daemon syslogd -r -m 0 --- > daemon syslogd -m 0 You're supposed to be able to stop using the system logger with the ZSYSLOG env var, which is set to "anything" in zserver.sh, but I didn't have any luck with unsetting that. I also had to set ZSYSLOG_SERVER for some reason. ZSYSLOG_SERVER=127.0.0.1:514 Look in /var/log/messages to see that you're getting logs.

I like the idea of abstracting html controls into cross-browser(environment) widgets but I don't think it will work very well in the same way that java AWT didn't work. To get it to work will mean the lowest common denominator of all rendered platforms is used. Also people care to much about presentation and want to get under the covers. However for those that don't a class library of complicated controls would be cool, like the calander control that exists already. One I'd like to see is a add and remove control (the one with two lists like in the ZClass inheritance dialog). The problem with dialogs like this is to create them without javascript or DHTML you would need to abstract over more than one transaction. Even more impressive is multiligual idea. Zope can supposedly handle this by aquisition but does this work? I imagine to do this it would be something like root folder1 doc1.html folder2 doc2.html method anotherlang folder1 doc1.html folder2 doc2.html method And calling with /root/folder1/doc1.html or /root/anotherlang/folder1/doc1.html depending on the language. Another way of doing all this is to say that anyone object can have multiple alternative forms. Then have something in the context determine that form. Maybe each object has a small method that can get overridden to determine which form to return at any one request. This would work for images for instance with high and low bandwidth versions. The bigest advantage of this I think is that your then modifying one hierachy instead of many and therefore are less likely to make mistakes about propagating changes.
