ANN: ZCatalog 1.0.0 alpha
by Michel Pelletier 27 Jun '99

27 Jun '99

Greetings Zopeheads. After much sweat and toil and 4 rewrites, we are pleased to announce the release of ZCatalog, the Zope Cataloging and Searching Product, version 1.0.0 alpha. The Catalog can be found at: http://www.zope.org/Download/ZCatalog We recommend you read the ZCatalog Tutorial, written by Mike Pelletier (Note that 'Mike' Pelletier is a completely different person than 'Michel' Pelletier, which is me) which is available on the web at the above location. ZCatalog requires Zope 2.0.0alpha3. It will not work with any previous versions of Zope. Remember, this is *alpha* software. It has limitations, and there are several optimizations/features we have planed for it which are not included in this release. We would, however, like the tired to be well kicked. Please report any bugs you find related to ZCatalog to the Collector: http://www.zope.org/Collector We hope you find some interesting things to do with the Catalog! -Michel

I've been zope'd
by Alex Rice 27 Jun '99

I just want to thank everyone at DC and all you other hackers. Zope was impressive to begin with, but the addition of ZClasses and ZCatalogs is really an awesome addition to Zope. For those of you not yet tinkering with ZClasses and ZCatalogs, I highly recommend it :-) Having fun, Alex Rice | alrice(a)swcp.com | http://www.swcp.com/~alrice Current Location: N.

I suggest you use ZServer or Apache (or both). Your problem will go away then. -Michel > Subject is it.

On my list of things to do to catalog to optimize it is to improve upon the 'Status' view so that you can look inside the indexes and see how many words they are storing, and maybe some memory consumption statistics. Don't be suprised, however, if the indexes grow to two or three times the size of the data that is indexed. That is the nature of indexing. You may have noted from the code that ZCatalog uses 'UnIndex' and 'UnTextIndex'es. These are different from the usual Index and TextIndex modules that have come with Zope since 1.10.0. The 'Un' indexes are fully symetrical, meaning that not only do they have an index that maps from word to document id (and score) they also have an inverted index that maps from document id to word. The reason for this is because the Catalog can not allways track when an object changes (the only way it can do that is if the object notifies the catalog that it is about to change). 'Un' indexes then need to keep a little extra information around, so that when an object comes in to have itself Cataloged again, the Index can first find out what the old values of the object were (using the inverted index) unindex those, and then reindex the object. Pretty heavy stuff, although the use of fully symetrical indexes really simplified the design of the 'Un' indexes over those of the more memory efficient Indexes. > Just for kicks I loaded several MB of texts into DTML Docs and this is > where I found the memory problem. My setup is The several MB of text would probably translate into 2 or 3 times that in memory growth. However, the Persistence machinery will quickly start to deactivate unused portions of the index. Try tweaking your Cache settings to see if you can get Zope to be more aggresive about deactivating objects. -Michel > > Zope 2.0a3+ZServer+odb3+pcgi > Python 1.5.2 > Linux 2.2.9/x86 > > Alex Rice | alrice(a)swcp.com | http://www.swcp.com/~alrice > Current Location: N.

It probably *does* have permission to write to the Data.bbb file *in* the var directory (otherwise it wouldn't work at all). Since the database index file is just an optimization, and not required for Zope to start up, everything works for you until your Zope process tries to save the index file. > > > help is highly appreciated. what i am working on is an intranet-based > customer database with web front-end. this is a class project for my > master's program and i intend on dazzling the professor, whose solutions and > projects almost always exclusively involve micro$oft-trash, of which i am > utterly sick after a few projects with e.g. SQL server and ASP. > I would not suggest running ZopeHTTPServer for a grade. It is not production software. It was intended to allow people to quicky try out Zope back before we had ZServer, but now that there is ZServer, and it is just as simple to use as as ZopeHTTPServer, I would suggest trying that. Now that I think about it, I propose that we unbundle ZopeHTTPServer from all future releases of Zope. -Michel > :) > > Jens Vagelpohl > > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev )

RE: [Zope] Tree tag and SQL methods?
by Alexander Staubo 26 Jun '99

26 Jun '99

Doesn't improve anything: While the "second" part of the query -- the one that's supposed to collect the leaf articles -- clearly executes, no data is displayed. Only the first level -- the publications list -- is rendered, with "plus" icons. Clicking on the icon runs the query but no data is there. This is 1.11.0pr1, though, so maybe the problem is related to this release. I wish I could say I was working with 2.0.0a3, but if you've followed my last few posts you know why I can't. :-) -- Alexander Staubo http://www.mop.no/~alex/ "What the hell, he thought, you're only young once, and threw himself out of the window.
