June 1999 - Zope-Dev

using searchindex type stuff from ZClasses.
by Anthony Baxter 24 Jun '99

24 Jun '99

I want to add support for the SearchIndex tools to a ZClass-based simple tasklist product (think Collector-lite-lite). The way I've been working on this so far is with external methods - but it's a bit painful. Are there any better ways to do this? Maybe expose some of the search machinery via the ZClass interface?

Zope XML-RPC with SQL Methods
by David White 24 Jun '99

24 Jun '99

Hi All, I've been playing around a bit with the recently added XML-RPC support for Zope, graciously added by Eric Kidd ( Thank you Eric! ) and have been able to create External Methods and access them remotely from two different XML-RPC clients ( xmlrpclib in Python and Frontier::Client in Perl). This is all VERY cool! I was then wondering if it would be possible to directly call a SQL Method from the client and get results ( ok maybe I was reaching too far too quick, but what the heck I gave it a shot...). This of course did not work. I tried a variety of different SQL methods (all selects ranging from returning single result record to returning multiple record sets). It seems as though SQL Methods are not directly callable from the web, but rather must be referenced from another DTML method/document. When I do try to directly call a SQL Method from the web it always tries to take me to the 'manage_TestForm' for the method. It seems that 'index_html' always redirects there. Is there some deep level of Zen for why this must be the case? Are there security implications if SQL Methods were directly callable? It seems to me that to be able to do: import xmlrpclib s = xmlrpclib.Server("http://somemachine.domain/") result_records = s.method_folder.some_sql_method() would be just WAY TOO COOL! What would it take to make SQL methods directly callable from XML-RPC? Am I just missing something? (very possible :^) Thanks in advance, Dave -- ---------------------------------------------------- David R. White Raytheon Electronic Systems Process Support (508) 440-2087 528 Boston Post Rd.

That's the nice thing about Zope. It stores the Confera _data_, not copies of the Confera program. Updating from 1.2.0 to 1.3.0 doesn't affect the messages stored in your Zope system. Any further use of Confera (be it new or existing instances) will include the new features. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------

How to update products?
by Thilo Mezger 24 Jun '99

24 Jun '99

hi! i was wondering if someone has already developed a strategy how to update products in zope. for example, you are running a site that uses the Confera-1.2.0 product and it is populated by several thousands of messages. now DC releases a bug-fix version 1.3.0 of this product. you can put that in your lib/python/Products folder, restart zope and newly created confera's will be version 1.3.0 of course. but how can i update my old and running confera system from 1.2 to 1.3? an instance from the (here) Confera class is created when you create a new Confera object in the management interface and the class definition is saved with this instance somehow?! unlike zclasses. could anyone shed some light on this problem/phenomena please? thanks thilo

ANNOUNCE: Enhanced ZLDAPConnection Object
by Scott Robertson 23 Jun '99

23 Jun '99

I just uploaded an enahnced LDAP Connection Object based on Anthony Baxter's ZLDAPconn. It's in the contrib section of zope.org This is still pretty beta, and it should probally be merged with Anthony's if he has anything new. Feedback encouraged. --------------------------------------------------- - Scott Robertson Phone: 714.972.2299 - - CodeIt Computing Fax: 714.972.2399 - - http://codeit.com - ---------------------------------------------------

Zope, VirtualHosts, mod_rewrite and you.
by ngarcia 23 Jun '99

23 Jun '99

Here's the situation: We use VirtualHosts that look like this: <VirtualHost 127.0.0.1> RewriteEngine on RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule ^/(.*) /home/httpd/cgi-bin/Zope.cgi/site1/$1 [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l] </VirtualHost> <VirtualHost 127.0.0.2> RewriteEngine on RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule ^/(.*) /home/httpd/cgi-bin/Zope.cgi/site2/$1 [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l] </VirtualHost> On the surface, everything rewrites fine. The problem is that for some reason, the rewrite action gets called twice. The first time, it rewrites correctly, and everything looks the way it should. The second time it gets called, it sets the PATH_TRANSLATED to /home/httpd/cgi-bin/Zope.cgi/site1/site1/whatever.html which is causing some problems. So basically, my question is this: Why is the rewrite rule getting called twice? The first time it recognizes it as the initial call, and it calls the second one subreq. I have the rewrite log with RewriteLogLevel set to 9 if anyone wants to see it. Nick Garcia | ngarcia(a)codeit.com CodeIt Computing | http://codeit.com

Converting databases
by michel＠digicool.com 23 Jun '99

23 Jun '99

I hope I'm not jumping the gun here, but I tested the first round of Jim's database conversion script today. The first run was not sucessful, due to the laxer nature of ZOSB2's transaction format. After scoping that bug, Jim fixed things so that my ZODB2 database converted cleanly into a ZODB3 one. The script can be found in the latest CVS in the utilities directory. The command is: python1.5.2 bbb.py -f input.database output.database We would like some people to test this against their ZODB2 databases, but PLEASE: - be careful. Back up *all* of your data to a safe place before attempting it. - report any conversion bugs or tracebacks to the list and support(a)digicool.com. We are interested in your experiences with the script. - we only recomment this for 2.0 alpha users who have a nice fat ZODB2 database they want to convert over. This is *not* stable software. This is the very first revision. It will probably break for some people, we want those people to help us improve it, but please come into the experiment with the intention that something will go wrong, and *send in those bug reports* we do pay attention to them. Thanks! -Michel

This is the intended behavior (lib/python/Shared/DC/ZRDB/DA.py line 312): def index_html(self, URL1): " " raise 'Redirect', ("%s/manage_testForm" % URL1) (notice our verbose doc strings ;) > > Is there some deep level of Zen for why this must be the > case?

I don't want to jump the gun, but I suspect that the XML-RPC code is using REQUEST.traverse to resolve objects, and traverse will try and get a default index_html method for objects. XML_RPC needs to call the object directly, meaning the __call__ method of the SQL object needs to be called directly. If it is the case that XML-RPC uses REQUEST.traverse, you might want to look into REQUEST.resolve_url(). However, I could be wrong. -Michel > would be just WAY TOO COOL!
