VirtualHost ProxyPass settings
by Peter Bengtsson 09 Apr '03

09 Apr '03

From my httpd.conf:: <VirtualHost 80.82.139.4:80 80.82.139.11:80> ServerAdmin mail(a)peterbe.com ServerName it.ourdomainname.com ProxyRequests On ProxyPass / http://ourdomainname.com:8088/VirtualHostBase/http/it.ourdomainname.com:80/… ProxyPassReverse / http://ourdomainname.com:8088/VirtualHostBase/http/it.ourdomainname.com:80/… ProxyPass /misc_ http://ourdomainname.com:8088/misc_ ProxyPass /p_ http://ourdomainname.com:8088/p_ ProxyVia on ErrorLog /var/log/apache/it_domain_8091.error_log </VirtualHost> In the local zope running on port 8088 there's a folder called /it as expected. The problem is that if you visit it.ourdomainname.com and look at what <dtml-var absolute_url> gives you get http://it.ourdomainname.com/it That last bit there shouldn't be there!! Why?? I have a VirtualHostMonster object in the root and the site works fine if you just go via http://ourdomainname.com:8088/it Any ideas why I get this extra path? Peter

big problem when upgrading from2.5.1 to 2.6.1
by Jerome Alet 09 Apr '03

09 Apr '03

Hi, After having upgraded from Debian's Zope 2.5.1 to 2.6.1 we encounter a very big problem with some ZClasses of us. As soon as we try to go to the control panel and see our TTW product's content, we've got a traceback like the one attached to this message. It seems that some module's docstrings appear on the stack... I've googled a bit, and found that other people encountered a similar problem when upgrading, but I didn't find any answer. Is this problem known ? Any hint ? (Except doing away completely with ZClasses, which I'm already convinced of) Do you think I can downgrade to 2.5.1 without loosing anything ? (I haven't touched anything yet, doing a backup excepted) Thanks in advance. Jerome Alet

zsql puzzler
by jwsacksteder＠ramprecision.com 09 Apr '03

09 Apr '03

I have a zsql method that is acting rather oddly. My query is something like this- select girl,type,sum(qty) from girlscout_cookie_sales group by girl,type If I enter it directly in my console, I get a list of about 40 lines. If I paste that query into a zsql method, I only get 21 results and no error. The results are not being cached. I am not displaying 20 results at a time. Where are my results? I'm stumped as to how to begin troubleshooting this.

Trouble with CookieCrumbler in a folder
by John Coleman 09 Apr '03

09 Apr '03

Using Zope 2.5.1 with python 2.1.3 on Linux (RH 7.1). For some reason when I put a CookieCrumbler(0.5) instance in a folder, I hit the redirection limit when accessing the folder's index_html. I'm using LDAPUserFolder 2.0 in the same folder. Even pointing directly to the login_form doesn't work. I've removed references to standard_html_footer and standard_html_header from the dtml method created. I've made sure anonymous users have permission on the login_form method. I've tried checking both the "Always redirect" and "Use cookie paths" options, and neither seems to help. The kicker is that it works just fine if I drop the CookieCrumbler in the root folder. Can anyone offer a suggestion? I couldn't find anything about this topic in a search of the archives (limited as that search is). Thanks, -- John Coleman jcoleman(a)sbc.edu

Re: Some Q about Zope under Linux

> I can't find file SETUID.txt like you suggested in my zope's folder. > FYI I'm using Zope 2.4.0. Is that file exist in another version of > Zope? Can I download it? If can , where can I download it? Yes, you're right! It's not in Zope 2.4.0, but in 2.6.1. I just suggest you to upgrade since the last stable version corrects the bugs that 2.5.1 and older versions of zope have. Another thing is that some products don't support old versions anymore. Finally, don't postpone your upgrade too much, you'll have probably to face lots of issues related to this process, keep in mind that zope is continuosly evolving. I also advice you to have a look at the text files inside the folder "doc" of your zope installation and also read the zope book: http://www.zope.org/Documentation/Books/ZopeBook/current/IntroducingZope.stx Regards, Josef

MailForm Tutorial: how do I get a SMTP host?
by Paul K 09 Apr '03

09 Apr '03

Hello all, This is not strictly speaking a question about zope, but my problem may be one that others have encountered and solved. I have been working through the tutorial on how to create a mail form: http://www.zope.org/Documentation/How-To/MailForm One slight hitch: I don't have an SMPT host. So my question is: how do I acquire one and get it working? Do I need to install an email server? Is there a good free open source email server for Windows that I could use? I should say: I am working on a networked Windows machine with an internet connection, and have a web-based email account. Many thanks in advance for any advice.

Zope Win32 service (was RE: [Zope] Binary Compatibility)
by Adam Getchell 09 Apr '03

09 Apr '03

Lukas, It doesn't appear to be the case if you're running Zope under Windows. Uninstalling Zope-2.5.1 doesn't remove the Zope service, and when you install 2.6.0 the Zope service pointing to $INSTANCE_HOME/bin/lib/win32/pythonservice.exe no longer functions. Is there a workaround for this? (ie, a way to uninstall and reinstall the service). I've seen this happen on 3 zope machines, so it's reproducible. Thanks, -----Original Message----- From: Lukas Zapletal [mailto:lzap@root.cz] Sent: Tuesday, October 22, 2002 5:41 AM To: zope(a)zope.org Subject: [Zope] Binary Compatibility Dears When I move out data.fs from v2.5.1, install 2.6.0 and move data.fs back will everything ok?

AW: [Zope] Cookieless Session Management
by Germer, Carsten 09 Apr '03

09 Apr '03

Hi there, just a quick note on the subject. Cookieless session management can store the session ID in hidden form elements, URL insertions, it can use referer, browserversion and IP-address, etc. and mix all these to track the session/user. I know ZOPE CookielessSession uses URL insertions, not sure if it uses the other tricks as well. The problem with cookieless session management in general is that it's less reliable. If you use cookies you got em or not. If you use the other techniques you _might_ run into a bunch of strange problems. URL-Insertion with Flash or Javascript? Not always possible. IP-tracking with more then one user behind a NAT-Router? Hardly. Users browsing your site with two instances of the same browser on their desktop? Bummer. I don't love cookies very much myself but if you run a site which may have things like Flash or Javascript and especially if you run applications that need to rely heavily on the session management (Shopping, complex administration, login via form and not popup, etc.) I would strongly advise to use cookies unless you know exactly what you're site is doing and how. Not really that much Zope but I hope this helps :) /Gem > > On Mon, 2003-04-07 at 18:31, hpinson(a)indepthl.com wrote: > > Hi Chris-- thanks for the reference. > > > > Is there some drawback to using a session model that stores session > > information in server memory (CookielessSession) as opposed > to a URL- > > based" sessioning mechanism, like Zope uses? > > Somehow state needs to be kept between requests to implement > sessioning.

java crashes zope
by Lester Cram 09 Apr '03

09 Apr '03

I have a small applet compiled under sun java which works when tested on local disk. When trying to run it after uploding it to zope, java asks for reconfirmation of username and password and then crashes zope and sometimes my client pc. If I restart zope (with webmin) and reconnect to the site I am again asked for user and password by java but this time the applet runs perfectly. Is this a bug in this version of java or is there another reason???? Any thoughts appreciated
