Library for huge text indexes ..
by Jean Jordaan 29 May '02

29 May '02

Just spotted this and wondered if it might be of interest to people working on Zope's indexing capacity .. http://www.gnu.org/software/mifluz/description.en.html The purpose of GNU mifluz is to provide a C++ library to build and query a full text inverted index. It is dynamically updatable, scalable (up to 1Tb indexes), uses a controlled amount of memory, shares index files and memory cache among processes or threads and compresses index files to 50% of the raw data. The structure of the index is configurable at runtime and allows inclusion of relevance ranking information. The query functions do not require to load all the occurences of a searched term. They consume very few resources and many searches can be run in parallel. -- Jean Jordaan Upfront Systems http://www.upfrontsystems.co.za

Replacing default Python with ActiveState 2.1.3
by hpinson＠indepthl.com 29 May '02

29 May '02

Hello. I am trying to replace the standard zope Python with the ActiveState version (2.1.3) so that I may enable Perl scripting. Can anyone tell me what paths, in what files, have to be changed in the Zope configuration to point to the new Python? My zope is at d:\zope My Python is at c:\program files\python If there is a howto on this that anyone knows about-- this would be useful too? Thanks.

RE: [Zope] Zope alone or under Apache
by Meilicke, Scott 29 May '02

29 May '02

My experience with a low volume personal site on linux (debian), versions 2.3.x through 2.4.3, is that zserver crashed every few days. When I put Apache in front with mod_proxy, it no longer crashes. This site is exposed to the Internet. At work I use zope 2.4.3 on windows, no apache or IIS, and I have never seen it crash, but it is not exposed to the Internet either.

Are there any advantages to running Zope under Apache that would make the decrease in speed worthwhile? There seem to be plenty of zope products available to take care of things missing in zope like cgi-bin, etc. I'd be grateful for any "personal experiences" people would have to offer.

Zope's version of python
by Patrick Hresko 29 May '02

29 May '02

Hello, I am looking to do XSLT transformations with Apache's Xalan engine. I am also using Pyana to interface python with Xalan. I am under the impression that Zope uses its own version of Python (2.1.2). I was wandering how I would go about installing modules so that Zope's version of python would recognize them. Thanks, Patrick Hresko

Apache 1.3.22 / 1.3.23 on RedHat 7.2/7.3
by Adam Manock 29 May '02

29 May '02

I'm currently evaluating RedHat 7.3 for use on our servers. We're currently standardized on RH7.2 with few problems, unless you count maintaining a 1.2Gb mirror of updates.redhat.com/7.2/en/os/ errata packages a problem :-) A little advance digging for potential sticking points revealed the mod_proxy cookie bug: http://nagoya.apache.org/bugzilla/show_bug.cgi?id=7195 So, has anyone tried using RedHat's apache-1.3.22-2 packages from RH7.2 errata on RH7.3?

getitem from python
by Roman Bogoyev 29 May '02

29 May '02

Please excuse this newbie question: How do I refer to an object from a variable in a python script? eg: Have a document named 'mydoc' in the current folder where this script lives: print context.mydoc.title_or_id() works but I want fred = 'mydoc' print context.fred.title_or_id() which obviously doesn't. So I need to turn the string 'mydoc' into an object reference. Something like the dtml 'getitem'?? -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Roman Bogoyev, Computer Systems Manager, email: roman(a)maths.uwa.edu.au UWA Maths, 35 Stirling Hwy, Crawley, phone: +61 8 9380 3379 Western Australia 6009 fax: +61 8 9380 1028

Accessing Zope Object properties
by Kirk Lowery 29 May '02

29 May '02

I want to put a "Last edited on <Zope Object modification date>" in a footer, so that I don't have to think about manually changing the date all the time. I've looked through the docs, but I can't find (or recognize) what I need. And it raises the general question: how do I discover and access the properties of any arbitrary Zope object for binding to variables, manipulation, etc.? TIA. Kirk

Storing documents and metadata (associated XML fragment)
by Lars von Wedel 29 May '02

29 May '02

Hello, I want to store some kind of library of arbitrary files (similar to the file library example in the distribution). Further, I'd like to store an associated XML fragment (metadata) with the document. This XML fragment should be accessible externally, via XML-RPC for example. What is the best way to store such things in Zope? Would I store Metadata in separate files along with the original files? Or should I extend the File with a string member to hold metadata (may be large, though)? Any other suggestions? Thanks in advance, Lars
