RAM chache and characterset
by Ulrich Wisser 05 Aug '04

Hi, my whole application uses UTF-8. Now I started to make some performance tweaks and ran into a lot of trouble. It seems that RAM CACHE MANAGER does not work very well with UTF-8 documents. Is this a known problem? How can it be solved? Thanks Ulrich

Bug in Zope-2.7.2-0-win32.exe
by Joe Goldthwaite 05 Aug '04

05 Aug '04

I think I've come across a bug in the current stable release of the Windows Zope distribution. Everything works except the option to start Zope as a service is not functioning. I thought something was wrong with Windows since the registry entries for the Zope instance service were not being made. On a hunch, I finally tried the 2.7.1 release and it worked. I'm not sure how to report the bug. I checked the web site but couldn't find any place to make a bug report. If any of you guys know where to do it could you either point me in the proper direction or forward this message to them? Thanks! Joe Goldthwaite

Textarea changes vanishing... my bad, or is IE evil?
by Paul Winkler 05 Aug '04

05 Aug '04

Sorry for borderline-off-topic posting, but I'd like to see if anyone else in zope-land is observing this behavior... Some of my zope users have been complaining recently that their edits mysteriously vanish. Today we came up with a consistently reproducible case: 1. go to any page template... let's call it my_template 2. make some changes and submit 3. navigate to somewhere else 4. navigate back to my_template's edit form (not using the back button, but i don't know if that matters). Now the textarea shows the text as it was at step 1, when it should show the text as it was after step 2. At this point, if you hit refresh, your changes from step 2 show up and all is good. But if you forget to do so, you'll be editing stale text and wiping out the work you did in step 2. Changing the Internet Options settings does not help... we've all got it set to check for new versions every time. The reason I am suspicious of IE is that I cannot reproduce the bad behavior with any mozilla-based browser that I've tried (firefox/linux, mozilla 1.5/linux, netscape 7.1 / w2k). We've only seen this for a few weeks so I'm wondering if it could be part of a windows update IE fix. But the really maddenign thing is that now I can't reproduce the behavior on a fresh zope 2.7.0 instance. Sigh... maybe I just have some bad AcceleratedHTTPCacheManager settings somewhere but I really can't find anything suspicious so far. Any other ideas, anyone? -- Paul Winkler http://www.slinkp.com

debug info
by John Hunter 04 Aug '04

04 Aug '04

I am having a problem with roles and permissions. I find that I cannot access some pages on my site unless I have the role Manager, although I have tried to customize the roles and permissions so that other roles can access this content. Actually, this used to be working and now it is no longer working and I'm trying to figure out what has changed. When I try and access the protected content, I am prompted for a user name and passwd. If I enter a user who does not have the Manager role, I get the error You are not authorized to access this resource. Username and password are not correct. If I add the Manager role for that user, however, I can then access the content. The site is built as a python Product, and I am using ClassSecurityInfo to manage my permissions and roles for the various methods. My question is: is there any way I can get better diagnostic information for debugging, for example what resource I am trying to acquire that I don't have permission for? I've checked the Z2.log but there is no helpful information there. On a related note, is there any way to get zope to give full tracebacks rather than the limited tracebacks it supplies by default? Thanks, John Hunter zope 2.7

performance issue?
by Sophia Grimm 04 Aug '04

04 Aug '04

Using Zope 2.7.1 with LocalFS1.3 on Mac OS X Server 10.3.4: We have a Folder object named "Financials" containing several hundred Local File System objects representing accounts. From within Financials, when the manager tries to copy and paste LocalFS objects, to delete them, or to move them into sub-folders, she gets a forever-spinning cursor. Eventually she gets annoyed and leaves the manage page. When she comes back to it, her tasks have been completed. Is this a performance issue related to the number of Local File System objects in the folder? Is it a general Zope issue? Many thanks for your help. __________________________________ Do you Yahoo!?

[Ann] ManagableIndex 0.9 -- flexible indexing construction framework with Field-, Keyword-, Range- and WordIndex
by Dieter Maurer 04 Aug '04

04 Aug '04

ManagableIndex is a flexible framework to build efficient and easily customizable indexes. It comes with flexible, efficient and easily tailorable Field-, Keyword-, Range- and WordIndexes. New in version 0.9: * most string and unicode indexes (exception <code>RangeIndex</code>) now support glob and regular expression matching. Usually, only text indexes support glob matching. No other Zope index types (I know of) support regular expression matching. * a new WordIndex -- which is a minimal TextIndex without phrase searches, relevance ranking and integrated query parser. Its development was motivated by the observation that full text searches were slowed down immensely by loading large amounts of word frequency information (used for relevance ranking). This same information also caused transactions of almost 700 MB for documents of a few kB. As we sort all results by other criteria, the overhead for the unused relevance ranking was far too high. A WordIndex is expected to have minimal transaction sizes (during indexing) and minimal load times (during searching). As it does not include its own query parser, you need a flexible external query framework such as 'AdvancedQuery' or 'CatalogQuery' to make effective use of a WordIndex. More information and download: <http://www.dieter.handshake.de/pyprojects/zope#ManagableIndex> Note: This may be the last version with its current open source unrestricted use license. I consider whether I will expressly forbid the use of my software by institutions of the European Union (Councel of Ministers, Commission, Parliament, ...). This is in protest against a recent decision of the Councel to make software patentable. This decision ignores a Parliament vote that pleaded to keep logic (algorithms, business rules) un-patentable. -- Dieter

[Ann] AdvancedQuery 0.5: flexible queries in Zope
by Dieter Maurer 04 Aug '04

04 Aug '04

AdvancedQuery is a Zope product for flexible queries against "ZCatalog" or "CatalogTool". Queries can be arbitrarily combined with "and", "or" and "not". All index types are almost fully supported (exception: relevance sorting of TextIndexes). AdvancedQuery supports efficient incremental (lazy) multi-level sorting via FieldIndexes. This means, you can sort via e.g. "sort_on=(('Date','desc'), 'portal_type', 'id')". For large result sets, sorting is performed incrementally, only as far as you access the result. This can drastically speed up sorting time. AdvancedQuery is especially efficient for "ManagableIndex"es (see: <http://www.dieter.handshake.de/pyprojects/zope#ManagableIndex>). Version 0.5 supports the new glob and regexp matching queries of "ManagableIndex". More information and download: <http://www.dieter.handshake.de/pyprojects/zope#AdvancedQuery> Note: This may be the last version with its current open source unrestricted use license. I consider whether I will expressly forbid the use of my software by institutions of the European Union (Councel of Ministers, Commission, Parliament, ...). This is in protest against a recent decision of the Councel to make software patentable.

ZClass Distribution Question
by Jonathan Cyr 04 Aug '04

04 Aug '04

Hello, I've developed an online app using ZClasses for components... After seeing some threads arguing about ZClass quality, I have a question. I'm planning to use the Distribute function of the ZClass to move them to my ZEO setup, eliiminating the possibility of editing them in production. Are there any known problems with the Distribution mechanism... I noticed it generates an unreadable binary file of some kind. Do ZClass Distributions with higher versions replace former versions well.... any lost references, etc. Just need some ZClass confidence from someone who's been there. I am commited to ZClass's, at this point, just need constructive advice. -Jon
