Found an fatal error in Zope 2.3.0 :)
by Radek Hnilica 31 Jan '01

31 Jan '01

Hello all, While trying to debianize, compile and install new zope 2.3.0 I found that file z2.py doesn't contain necesary first line. I look to previous version 2.2.4 and there it is. #!/usr/bin/env python The source was taken from zope.org. I'v also look at CVS and there it's missing to. -- Radek Hnilica <Radek_Hnilica at LinuxFan dot COM>

SiteAccess affects the Zope management interface
by Fred Yankowski 31 Jan '01

31 Jan '01

I hadn't realized it before, but SiteAccess can cause really confusing things in the Zope management interface! When I installed Zope 2.3.0 and ran it on an unused port number to check it out while the main Zope was still running, the top-level Zope folder displayed with the new look (which is very well done, BTW), but when I would drill down into a folder governed by a SiteRoot object the folders appeared with the old (2.2.x) look. This was quite a mystery until I realized that although the tree frame on the left (and the new top frame) were displaying pages served by the new Zope 2.3.0 process, the right/folder frame was actually displaying a page served by my older production Zope process running Zope 2.2.5! My Zope tree is something like this: / + /subsite1 + /subsite2 subsite1 has a SiteRoot that gives the folder a new Base of "http://subsite1.org". Apache is sitting on port 80 and using ProxyPass to map http://subsite1.org to http://myhost.org:8080/subsite1. Assume the new Zope ZServer is running on port 9090. So the listing for 'subsite1' in the tree display has an HREF of http://myhost.org:9090/subsite1/manage_main. When I click on that, the browser requests that URL from Zope on myhost.org:9090. Because of the SiteRoot object, the server sends back an HTTP 302 response redirecting the browser to http://subsite1.org/manage_main, which the browser dutifully requests. The Apache server gets that request and forwards it via ProxyPass to http://myhost.org:8080/subsite1/manage_main. The other/older Zope server on port 8080 fields that request (with SiteAccess converting URLs) and sends it back to the browser, which displays it in the large/right frame. So now the left frame is displaying the objects served by ZServer on port 8080 but the right frame is displaying the contents of some object served by ZServer on port 9090. One outcome of this for me is that I will now test the staging server by running it this way (from bash): SUPPRESS_SITEROOT=1 ./start.bat so that SiteRoot translations are disabled. -- Fred Yankowski fred(a)OntoSys.com tel: +1.630.879.1312 Principal Consultant www.OntoSys.com fax: +1.630.879.1370 OntoSys, Inc 38W242 Deerpath Rd, Batavia, IL 60510, USA

Visual Foxpro Database Connection Question
by Mike McConnell 31 Jan '01

31 Jan '01

I am a real Zope newbie so bear with me. I am attempting to set up an ODBC connection in Zope to access a Visual FoxPro database and get the following error: sql.error: ('S0002', 173, "[Microsoft] [ODBC Visual Foxpro Driver]File 'users.dbf' does not exist.") There are multiple tables and it cannot find any of them. The database connection within Zope shows it is open successfully. Particulars: NT WS 4.0 SP3 Zope 2.2.4 ODBCDA Visual Foxpro database is on a Novell 4.11 server Thanks for any assistance. Mike

ZWiki-FastCGI-SiteAccess
by Ronald L. Roeber 31 Jan '01

31 Jan '01

We are running Zope (2.3) with Apache and fastcgi. As such our Zope applications are found in: http://ourserver.domain.edu/zope This works really well (so far) for most applications we use and have built except for ZWiki. I can make ZWikis work by adding "zope/" to wherever &dtml-wiki_base_url is found (for the most part). I'm struggling with SiteAccess. The examples given on the website haven't been helpful to me (yes I'm dense) since "zope/" is not within the scope of REQUEST.steps. Has anyone dealt with this problem before? If not I will keep banging my head until I get it right. If I could wish, I would wish for a collection of "Practical Solutions Using SiteAccess" patterned after those developed by Ralf S. Engelschall concerning the use of mod_rewrite in Apache 1.3: http://httpd.apache.org/docs/misc/rewriteguide.html Perhaps, this is sort of what is on the Zope web site under SiteAccess, but It doesn't jump right out at me.

A little sqltest patch: op=ne multiple
by Shai Berger 31 Jan '01

31 Jan '01

Hi guys, The following trivial patch lets dtml-sqltest make sense of multiple inequality tests, that is: Currently <dtml-sqltest name op="ne" multiple> has the funny behavior of rendering name<>val when passed a single value, and name in (val1,val2) when a list is passed. With this fix, the latter case becomes name not in (val1,val2) (It might be considered a good idea to take care of the other ops too, but that would be non-trivial ;-) Have fun, Shai. *** sqltest.py Wed Jan 31 19:42:15 2001 --- old_sqltest.py Tue May 30 18:46:55 2000 *************** *** 222,229 **** if len(vs) > 1: vs=join(map(str,vs),', ') - if (self.op == comparison_operators['ne']): - return "%s not in (%s)" % (self.column,vs) return "%s in (%s)" % (self.column,vs) return "%s %s %s" % (self.column, self.op, vs[0]) --- 222,227 ----

Testing the query with value= Test, the result is ok! thanks very much in advance axel

LoginManager in 2.3
by Phil Harris 31 Jan '01

31 Jan '01

All, Has anyone managed to get LoginManager working in 2.3 as the 'root' acl_users. It works fine in a folder, no errors etc, but when I come to move it to the root, I get all the right prompts of old, but at the moment of pasting it I am told that the emergency user can't own objects. OK fair enough, I understand the decision made, but has anyone got a recipe for moving a LoginManager to the root? tia Phil

David promptly replied: Hi Jerry, It's hard to diagnose from what you've sent me. Can you send me the full traceback (from the HTML source code of the error page)? That will make determining where the error occurred a lot easier.
