Weird Re-Indexing Errors after move to Zope 2.3.1b1
by Chris Withers 05 Mar '01

Hi, Since moving one of our servers from Zope 2.2.4 to 2.3.1b1, we've been frequently getting this weird error when trying to do something that requires an object to be re-indexed in the Catalog: Error Type: AttributeError Error Value: 'tuple' object has no attribute 'append' Traceback: Traceback (innermost last): <snip> File /usr/local/zope/cases/Products/aProduct/aProduct.py, line xxx, in index_something (Object: Traversable) File /usr/local/zope/Zope-2.3.1b1-src/lib/python/Products/ZCatalog/ZCatalog.py, line 411, in catalog_object (Object: Traversable) File /usr/local/zope/Zope-2.3.1b1-src/lib/python/Products/ZCatalog/Catalog.py, line 382, in catalogObject File /usr/local/zope/current/lib/python/SearchIndex/UnTextIndex.py, line 394, in index_object File /usr/local/zope/current/lib/python/SearchIndex/UnTextIndex.py, line 305, in insertReverseIndexEntry AttributeError: 'tuple' object has no attribute 'append' Any ideas what's going on here or how to fix it? cheers, Chris

Maybe, you can determine whether something relevant changed and call "catalog_object" only in this case. Dieter

ZPatterns, DynPersist.dll and Zope 2.3.0
by morten＠esol.no 04 Mar '01

Hi guys, I've got a problem making a version of the DynPersist.dll file work on windows. The message when trying to load the DynPersist module says (paraphrasing) "A unit attached to the system doesn't work". Anyone else experienced this? Also, I read that users of > Zope 2.2.x could skip this module, is there any quick hack to fix this? Thanks, Morten

Site Access Rewrite Rule documentation?
by R. David Murray 04 Mar '01

04 Mar '01

Is there any real documentation for Site Access rewrite rules anywhere? There isn't anything in the help system of 2.3.1b1, and the docs under SiteAccess on zope.org have a couple of examples but no technical explanation of how the parts of the example interact with Zope. My goal is pretty simple. I have a Specialist under /store/marketItems. I want my content managers to be able to use URLs like: /Books/someisbnnumber to refer to the object that is really at: /store/marketItems/someisbnnumber I could use a redirect, but why suffer the transaction overhead? I figured I could have a folder Books with an access rule like this: stack = context.REQUEST['TraversalRequestNameStack'] if stack[0]=='Books' and (len(stack)==1 or stack[1][:6]=='manage'): stack[0:1] = ['store','marketItems'] I figured I needed the manage thing so that I could edit the access rule. When I try to use this, no rewriting appears to happen. So I changed it to: if not stack[0][:6]=='manage': stack[0:1] = ['store','marketItems'] This didn't do anything for the URL '/Books', and gave me a notfound error on /Books/marketItems if I put something after the /Books. Changing it to stack[1:1] gives me a list index out of range. I can't figure out where *that* would be coming from. So, clearly I don't have a clue what stack is supposed to contain or what changing it does. Can anyone point me to docs or give me some help? You can also tell me, "that's stupid, just solve your problem this way"... --RDM

PlugIns: updated dtml files for ZPatterns+PlugIns
by Steve Alexander 04 Mar '01

04 Mar '01

Hi folks, I've updated the dtml files for Zope 2.3 for the PlugIns product. You can find them here: http://www.cat-box.net/steve/main.dtml http://www.cat-box.net/steve/PlugInGroup.dtml The update is to fix some badly formed HTML that makes the Zope Management Interface unusable with recent Mozilla builds. The same problem affects Zope 2.3 from public CVS. See Collector report 2020: http://classic.zope.org:8080/Collector/2020/view -- Steve Alexander Software Engineer Cat-Box limited

ZCatalog hackery
by morten＠esol.no 03 Mar '01

03 Mar '01

Hi guys, I've got a problem with ZCatalog. I've got plenty of large objects, ranging from 100KB to 100MB in size. Needless to say, these take up a lot of processor time when indexed by the ZCatalog. Now, these object have to be moved from time to time, only moved, so that one or two of the related columns and indexes are affected (the path and the parent container id); is there a way to go around this so that those two, the one column and the index are updated, and not, let's say the indexed body (which is 100KB - 100MB in size) ? Thanks, Morten

Authentication
by Philipp von Weitershausen 03 Mar '01

03 Mar '01

Hi there, I'm using Zope for a school's homepage. There is a small team of people managing the site. Their user definitions (in acl_users) have the "team" role wich is defined at the root folder. The "team" role is allowed to do everything except managing users. The team has been able to manage DTML Documents and Folders so far. Now I've written a tiny python product (using the how-to). And now they're not allowed to manage the properties of instances. Interesting enough, my self-defined permissions don't appear under "Security". What am I doing wrong? Here is a code sniplet out of my python code: __ac_permissions__= ( ('View management screens', ('manage_main', 'manage_InfoForm'), ('Manager,')), ('View', ('', 'index_html', 'getInfo', 'getPhoto'), ( 'Manager', 'Anonymous')), ('Add Image', ('manage_addImage',), ('Manager',)) ) ... Globals.default__class_init__( CkTeacher ) Another problem: A DTML Method calls objectValues() on the folder. Calling the method on any sub-folder works, but calling it on the root folder fails, even when I'm logged in as a Manager. I figured it fails because of some sub-object's permissions. Thanks in advance Phil. -- Philipp von Weitershausen [ *pronounce: "fun Viters-houzen" ] Web http://www.philikon.de

TransWarp preview release (AOP tools only)
by Phillip J. Eby 03 Mar '01

03 Mar '01

It's here... the first preview release of TransWarp. The bad news is, it only contains working versions of the aspect-oriented programming tools (the rest of the package is in flux). The good news is: 1. It's a *robust* working version, with 114 unit tests to prove it, and 2. There's state-of-the-art documentation, including such cutting-edge technology as tutorials, and super-simple examples. :) You can find the software at: http://www.zope.org/Members/pje/TransWarp/ and the online documentation at: http://www.zope.org/Members/pje/Wikis/TransWarp/ Comments welcome. Enjoy.

Re: [Zope-dev] ZDebug conflicts with MailHost?

A long time ago, there was firm evidence that ZDebug does not play well with "sendmail" (-> list archives). But, I had thought, this had been fixed. Dieter
