XMLRPC returns error sometimes
by Gijs Reulen 06 Aug '00

06 Aug '00

I am experimenting with xml-rpc and Zope. Some Methods from the API work ok, but others return an error. A common error is: Error Value: cannot marshal <extension class Acquisition.ImplicitAcquirerWrapper at 00C950F0> objects I receive this error for example when for Zope 2.1.6 I execute: ObjectManager.objectValues Where as the next Method works ok: ObjectManager.objectItems Maybe the to be returned info is to complex ?

RE: riddle me this Batman, coded copy/paste syntax?

This code worked fine in 2.1.6 but is broken (http://classic.zope.org:8080/Collector/1371/view) for me when moving zclass instances in 2.2.0 However...YMMV, so here it is for what it's worth. Note that thingstocopyidlist is just a list containing the object ids you want cloned from sourcefolder into targetfolder and that the clipboardstuff trick came out of a latenight reading of some python source deep in the bowels of zope.... <dtml-with "_.getitem(sourcefolder)"> <dtml-call "REQUEST.set('clipboardstuff',manage_copyObjects(ids=thingstocopyidlist))"> </dtml-with> <dtml-with "_.getitem(targetfolder)"> <dtml-call "manage_pasteObjects(cb_copy_data=clipboardstuff)"> </dtml-with> > The Zope quick reference lists the following methods > for the stock folder object: > > manage_copyObjects(self, ids, [REQUEST, RESPONSE]) > manage_cutObjects(self, ids, [REQUEST]) > manage_delObjects(self, [ids, REQUEST]) > manage_pasteObjects(self, [cb_copy_data, REQUEST]) > > For the life of me I can't get copy|cut and paste > to work even for the simplest of examples.

Sybase & Thread
by Nicholas Lo 06 Aug '00

06 Aug '00

Hi, I just wonder if anyone can help me with my problem. Recently, I've been working on creating a ZOPE product which requires periodic access to my Sybase. I have created a thread process using the Threading module. There is no problem of periodically wake up the thread and print something to the screen. So, I guess I have no problem with thread programming under ZOPE. However, when I add some database related routines to the thread, problems started to occur. I sometimes got '... not connected to the database'. When I did an SQL 'update', nothing has been updated on the database server when I actually looked into the database using isql. After a whole day of trial & error, now I've got 'ZOPE Memory Error'! I just wonder what has gone wrong. I really have no clue and my deadline is pressing :( 1) I want to know what is the proper way of using thread under ZOPE. 2) Is there any critical limitation of SybaseDAv2? 3) Can SybaseDAv2 & Threading live together happily? 4) What the role of ZODB in such situation? Thanks a million if anyone can help! Regards, Nick

Zope 2.2 under Debian (Woody) broken?
by Pedro I. Sanchez 06 Aug '00

06 Aug '00

Hello, I installed zope 2.2.0-1 from the Debian (Woody) distribution. No problems are reported during the installation but when I try to access http://localhost:9673/ I get the following error: Zope Error Zope has encountered an error while publishing this resource. Error Type: TypeError Error Value: unexpected keyword argument: validated_hook The same happens when I try to access the management menus. Is the Woody package broken? Any ideas? Thank you, -- Pedro

It would seem to be broken.... you might want to contact the package maintainer. I think it's Glyph Lefkowitz? > -----Original Message----- > From: Pedro I.

DA threading issues (was: server instability: ZODB corruption?)
by gyst＠nfg.nl 05 Aug '00

05 Aug '00

If I'm running current stable versions of Zope and Zope-MysqlDA, do I need to consider threading issues or are these safely abstracted away in the DA? "Luis Cortes" <LCortes(a)IMEME.NET> writes: > It may just be the version of Zope you have ( with regard to the Thread > problem ) there exists a version of zope that was known to cause the thread > death problem. You might want to check the patches or upgrade to a good > version. I'm running the Debian frozen release, i.e. 2.1.6 with security patches. Do you have any specific references on the thread problem? I find nothing on it in the changelogs I've found. Do I need to go to 2.2.0 for this? A seach on 'threading problem' turns up a hornet's nest of deep technical shit. Most of those mails are a year old, is this still an issue? As a developer, do I need to understand threading issues when developing database accessing products, or may I safely assume that threading, locking and transaction semantics are handled between the Database Adapter and Zope itself? I found a mail that says I should run Zope single-threaded when using MySQL: http://lists.zope.org/pipermail/zope/1999-July/006487.html Checking my installation, I find I have no threading option activated, which means I'll be running the default number of 4 threads. What will my server performance look like if I reduce this to 1 thread? Not that I'm having such a wonderful performance now, having my pager go off every hour :-( Is there a way to allocate different threads to different SiteRoot virtual websites, so I can lock a single site in a single thread but let my installation as a whole still retain some multi-threading performance? :*CU# -- *** Guido A.J.

LoginManager and ZPatterns - Sparse Install Docs, Help.
by Darin Lee 05 Aug '00

05 Aug '00

Zopistas, Maybe I'm making this harder than it needs to be. I want to set up a membership system for the site I am developing with Zope. I do not want to "restrict" any part of the site - instead I want a user to login (at their convenience) and then extend the "menu" options based on their group membership. If a user is not logged in - no problem, they just won't be able to view the advanced options - they'll still be able to surf the site (I want to maintain my user list in an external database as well). What is the best tool in Zope to accomplish this? After searching the site, I find there are several products - ACL Users, GUF, and LoginManager. Is GUF deprecated (The intro tends to give me this feeling)? Is LoginManager the way to go? It also appears GUF is more tailored toward restrictive authentication (I've already perused the "Using GUF with an SQL Database" how-to). I want a user to login (via HTML form/cookie) whenever they like, and get presented with additional menu options (based on their AUTHENICATED/GROUP status). Not have them try to access a "restricted" page (or type "manage") and get a basic authentication login box to get in. As far as LoginManager itself is concerned, I assume it requires ZPatterns. However, the Zpatterns install instructions are *very sparse.* How do I get the thing set up? Here's verbatim from the ZPatterns docs: ----- After unpacking the ZPatterns product, you will need to build this [c] >extension using the included Setup file in the ZPatterns directory. ----- How do I use the "Setup" file?? With the command "python Setup"? It doesn't say *how* to use it. ----- Please follow the standard procedures for building a Python module on your platform. (On Unix-ish systems, this usually consists of copying a Makefile.pre.in to the directory, then doing a make -f Makefile.pre.in boot >followed by make. ----- What are these standard procedures?? I built Python itself with "configure|Make|Make install". Where do I get this "Makefile.pre.in" file in the first place, from my Python src/build directory?? Correct me if I'm wrong, but there's usually some kind of script file to run that get's things going, or a "configure" script. I find none of this in the lib/python/Products/ZPatterns directory after I untarred it. So, I'm basically stumped. It doesn't appear GUF will do what I need, and I have failed on multiple attempts to get Loginmanager/ZPatterns installed. If someone could point me in the right direction on this I sure would appreciate it. Thanks much, -Darin Lee

Problems adding Properties to ZClass
by Erich Seifert 05 Aug '00

Hi, I'm having problems with adding Properties to a ZClass propertysheet. I always get an IndexError (no traceback, sorry) when I've hit the Add button. There are no special characters in the name ('Daten'). Does someone know what could be the problem? Thanks in advance Eric
