Hello Why not wxpython?why Tkinter ? The main reson wxpython doesnot provide the same GUI on Mac machine ( as far as I know.. infact it not ment for mac atall .. if im wrong correct me ;) ... now i mean platform independent .. which not just include Linux and Win ... I dont know how many ppl use it on Mac ( iMac ppl raise ur hands :) In fact Tkinter is also has some problem on Mac .. but it still manage. Well I'll luv to work with wxpython ..( which was earlier in my mind ) ... it gives u excellent 50 full fleged examples ... so all u got to do it Clt-C Clt-V ....In fact wxpython also support activeX ( they used IE in one of there examples) on win .. Now should u not care for thoze Apple guyz??? --------------------------------------------------- Raj Shastrakar <shastrakar(a)hbcse.tifr.res.in> ________________________________________________________________________ Everything you always wanted to know about cars and bikes,now at: http://in.autos.yahoo.com/cricket/tracker.html

Session & InvalidObjectReference
by p.t. 18 May '02

18 May '02

I'm trying to remember what was the last SQL query called registering to a session the "pointer" to a SQL instance, something like: anSQLquery = container.DB.SQL.anSQLqury Howevere, I get this error: Error Type: InvalidObjectReference Error Value: Attempt to store an object from a foreign database connection just when attempting to write to a session the variable anSQLquery. The traceback diagnostic is not very helping to me; it says: (Info: (('Products.Transience.TransientObject', 'TransientObject') referring to: Connection.py, line 345, in commit I did examine the code, but unfortunately my limited knowledge of such a sophisticated Python code gives me no possibility to uderstand what's wrong. Any suggestion on how to avoid this error message? TIA, p.t.

ZEO and Multiple Zope Sites
by eric.n.dunn＠bankofamerica.com 18 May '02

18 May '02

We're testing and upgrade from ZOPE 2.3.3 > ZOpe 2.5.1 with ZEO running We're having good success with both with only in Test environment (minimal users) Possible 3000 users hit Production ZServers Possible future problem. 1. Web site growth will cause Data.fs to become too large Solutions??? ? Mounting ZODB(s) Bottom line is... How do I prevent a meltdown of these present web sites when/if content too much for one ZServer to handle? Any and all suggestion will be gratefully accepted Eric Dunn

[ANN] TextIndexNG 1.0RC1 released
by Andreas Jung 17 May '02

17 May '02

I am pleased to announce the first release candidate of TextIndexNG V 1.0. TextIndexNG is a pluggable index for the ZCatalog that enhances the full text indexing capabilities of Zope by providing the following features: * support for document converters (HTML, PDF, WinWord, PowerPoint, Postscript). Custom converters can be easily added * stemmer support for 12 languages * support for right truncation * similarity search (soundex, metaphone support) (for english) * NEAR search * phrase search * pluggable query parsers (two parsers included) * stop words support * new test tab for interactive testing * 2-3 times faster than Zopes TextIndex (more to come ;-) ) * compatible with ASCII, ISO-8859-1 Requirements: * Zope 2.5 or Zope CVS trunk checkout Documentation: * http://www.zope.org/Members/ajung/TextIndexNG/wiki/ Download: * http://www.zope.org/Members/ajung/TextIndexNG/ Installation: * The installation is described in the Wiki (see above) Changes since alpha 2: * added new PyQueryParser (implements the same query syntax as QueryParser but it is a native Python implementation that will run on all platforms and does no longer require flex/bison). The benefits are locale support and unicode support on the parser level. * deprecated and removed QueryParser module * fixed memory leak in C extension for lexicons * added support for right trunctation to CLLexicon * right truncation is now always enabled (Lexicons are now using BTrees only instead of optimal dictionaries for better performance) Contact: * Andreas Jung, Email: andreas at andreas-jung.com

too large Data.fs ? There might be a problem with having the Zope Database (ZODB - Data.fs file) as one file and that is hitting the 2-gig file limit that occurs in many OS's and python. There is an article on "Recovering from hitting the 2 gig data base limit" at http://www.zope.org/Members/andym/2gig Check ZODB Roadmap at http://www.zope.org//Wikis/ZODB/ZODBRoadmap. ZODB storages, - FileStorage - bsddb3Storage - ReplicatedStorage - OracleStorage The first action plan should be to reduce the size of existing ZODB. The following are some of ways to reduce the ZODB size, 1> Pack ZODB Go to the root folder of Zope management screens. Click on "Control_Panel" and click on "Database Management". You can pack the database by removing previous revisions of objects. This will keep a backup of database as "Data.fs.old" (at Zope installation's var directory) and reduces the database size. 2> External File The ExtFile/ExtImage Product stores a file externally in the file system and keeps only meta data in the Zope Database. The file is stored in an external file repository and is accessible via its corresponding Zope object. Find more information at http://www.zope.org/Members/MacGregor/ExtFile 3> LocalFS The Local File System product allows you to access files from the server's local file system as if they were objects in the ZObject database. It also allows you to upload files to the file system. 4> Storing in External Database Consider storing your data in external databases like MySQL etc. There are Zope database connectors available for most of the databases (RDBMS). 5> Membership Data If your site has large member base and if you are storing membership data in ZODB, then you can consider the following options to store member data, - LDAP - MySQL User Folder - or other external storages 6> Break the Single Site into multiple Sites If your site is too large, you can as well consider to break the single site into multiple sites. You can have two or many Zope sites pointing to the same user folder (such as LDAP) for authentication. You can use SiteRoot to have logical URL names. If you use consistent style sheets, framework and GUI, users feel that it is a single Zope site. 7> Select OS Some OS's don't have this problem Solaris, Windows NT/2000, AIX, and FreeBSD (too name a few). Move the db to an os that supports large file system. Try 64-bit Linux, where Python 2.0 supports large files. Check the article "Recovering from hitting the 2 gig data base limit" at http://www.zope.org/Members/andym/2gig There are other ways to have multiple ZODBs : 1> Mountable Databases It would be desirable to mix multiple storages or multiple databases in the same of Zope object space. You can find an article on this at, http://www.zope.org//Members/jim/ZODB/MountedDatabases 2> MountedFileStorage There is a really simple Zope Product for mounting multiple ZODB files onto a Zope installation. You can find more information about the product at http://www.zope.org/Members/anthony/software/MountedFileStorage/ Members of Zope Community might have solved this issue in various innovative ways. If you can publish/send your solutions, I can consolidate all of them and publish an article on this on zope.org site.

ZSQL methods in a ZClass
by Tim Wilson 17 May '02

17 May '02

Hi everyone, I'm building a little ZClass that I intend to use as a wrapper of sorts around a bunch of ZSQL methods. The reason is that I want to give people access to this SQL database, but I don't want to litter the root of my Zope with bunches of ZSQL and DTML methods just so they can be acquired in various other folders. Putting DTML methods in as methods of the ZClass should work fine, but the ZSQL methods don't seem to work. I get a traceback when I attempt to view a DTML method that calls a ZSQL method. Am I trying something that isn't possible? Here's the traceback. I'm open to suggestions: (please forgive the ugly formatting of the traceback. I've recently changed to mutt as my MUA and it's doing this now.) Traceback (innermost last): File /home/wilson/zope/2.5.1b1/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /home/wilson/zope/2.5.1b1/lib/python/ZPublisher/Publish.py, line 114, in publish File /home/wilson/zope/2.5.1b1/lib/python/Zope/__init__.py, line 159, in zpublisher_exception_hook (Object: EventConduit) File /home/wilson/zope/2.5.1b1/lib/python/ZPublisher/Publish.py, line 98, in publish File /home/wilson/zope/2.5.1b1/lib/python/ZPublisher/mapply.py, line 88, in mapply (Object: rpt_locations) File /home/wilson/zope/2.5.1b1/lib/python/ZPublisher/Publish.py, line 39, in call_object (Object: rpt_locations) File /home/wilson/zope/2.5.1b1/lib/python/OFS/DTMLMethod.py, line 127, in __call__ (Object: rpt_locations) File /home/wilson/zope/2.5.1b1/lib/python/DocumentTemplate/DT_String.py, line 473, in __call__ (Object: rpt_locations) File /home/wilson/zope/2.5.1b1/lib/python/DocumentTemplate/DT_In.py, line 437, in renderwb (Object: qry_getlocations) KeyError: (see above) -Tim -- wilson(a)visi.com
