Zope Service Startup Failure
by g.kellett＠interalia-uk.com 09 Nov '05

09 Nov '05

I am having problems with Zope running on my Windows Web Server. This is quite a recent development (last two days) - things normally run perfectly well but lately the Zope service has stopped working. I get the following entry in the Zope event.log: 2005-11-08T20:51:13 INFO WinSignalHandler Caught signal SIGTERM ------ 2005-11-08T20:51:13 INFO Z2 Shutting down fast ------ 2005-11-08T20:51:13 INFO ZServer closing HTTP to new connections The windows system event log shows: The Zope instance at C:\Zope-Instance service terminated unexpectedly. It has done this 11 time(s). The only way I can get Zope to run is to execute runzope.bat - this is not very convenient as I have to start it manually and leave it running. If anyone can shed any light on how I can get the windows service back up and running I would be very grateful. Other notes: it is trying to use port 8080 - nothing else is trying to use this. I have tried altering the port that it uses and it makes no difference. Thanks in advance.

Re: [Zope] DateTime strftime problem

My point was that no, I can't comment on your real question. Too many people just dive in and change things so the tests pass without really looking closely at what they're doing. This is likely how DateTime got to be such a mess in the first place: works for me, must be okay! It's good to see someone paying some decent attention to this, I just hope you're paying real close attention and really understand the problem, 'cos it's a damn hard problem... cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

DateTime problem

I have the following code that works on one Zope install and does not work on another. I would like to be able to use the same code under both, but am at a loss as to why there is a difference. I do not control the Zope servers running this application.

Re: [Zope] VHM and SSL protection problem

Step number 7 shows this rewrite rule: > > RewriteRule ^/(.*) > http://localhost:8080/VirtualHostBase/https/www.yourmachinename.com:443/$1 Looking at what the zope witch <http://betabug.ch/zope/witch> tells me (and myself guessing at what you really want to do): RewriteRule ^$ \ http://127.0.0.1:8080/VirtualHostBase/\ https/%{SERVER_NAME}:443/VirtualHostRoot/ [L,P] RewriteRule ^/(.*) \ http://127.0.0.1:8080/VirtualHostBase/\ https/%{SERVER_NAME}:443/VirtualHostRoot/$1 [L,P] It seems that you are missing the [L,P] at the end, which tells apache what to do once a RewriteRule matches. > So if my original Zope site was > http://www.sg.com:8080/ > the above rule should simply rewrite the URL to > https://www.sg.com:443/ > which would force all requests for the http site to go > through SSL before being forwarded to Zope. Correct? No. What this does is it enables your site to be served through SSL and apache. The "force everything to SSL" rewriterule is another, different, second rule. You likely need both, though I have not used fastcgi in a while. The witch doesn't cover that rule style yet. For redirecting access to the ZMI to SSL, many people use rules like these: RewriteRule ^/(.*)/manage(.*) https://%{SERVER_NAME}/$1/manage$2 [R=301,L] RewriteRule ^/manage(.*) https://%{SERVER_NAME}/manage$1 [R=301,L] ProxyPassReverse /manage https://%{SERVER_NAME}/manage You could modify these to redirect everything to SSL. (There should either be additional tests to check that you are not using SSL already, or else this should be placed in the non-SSL virtual host setup). See how these have R=301 in the last part? That's a redirect, not a rewrite. Regards, Sascha

how to remove templates/scripts in ZMI from translated folders got from LinguaPlone...
by Lucia Colombo 08 Nov '05

08 Nov '05

Hi all, I'm working with Zope 2.7.7-final, python 2.3.5, Plone 2.1.1 and LinguaPlone 0.8.5. I'm posting here as the problem I'm having is within the ZMI and wonder if anybody could help me. I have migrated some multilingual sites from Plone 2.05 to Plone 2.1.1, and in such sites I had some templates/scripts in content folders, both in the default site language and in the translated ones. Now, some of them I actually had to change, some other ones I would just remove. Everything is ok for folders in the default site language, but since Plone 2.1.1 I'm not able any longer to list within the ZMI the translated folder on its own, I mean when I click the translated folder in the site tree, for example I want to go and see the translated folder for "company", "company-tr", then I would get to "company-tr/company/company". So I can't list the contents of "company-tr". I can actually locate the scripts/templates in the translated folders, searching by id in the site through the ZMI. But once I located them, I can possibly edit them but not remove them, as I can't list the folder contents. Any help would be appreciated. Lucia

Which part of Zope cares about interfaces in Products?
by Hideo at Yokohama 08 Nov '05

08 Nov '05

Hi. I'm trying to learn how to code Plone products using Archetypes, but to get a sound understanding, I'm going through layer by layer, starting from Zope products written in Python. I have been trying Plone for about 6 months. My Python experience is very limited. In Zope Developer's guide at zope.org, it says that when you make products you should define the interface of your product and make the implementation class implement that interface. I understand that this "interface" is not a built in feature of Python, but a convention introduced by Zope. By following the convention, you get some introspection capabilities that is provided by Zope libraries. From my experience with OOP in Java and C++, using interfaces makes sense only when some code knows that interface and codes against it, or some introspection based tool (typically a GUI builder or RMI/CORBA-ish tool) will study your interface and do something based on that knowledge. What is not clear to me is the effect of declaring the interface of Zope products. How does Zope care about it? In "The definitive guide to Plone", the product example does not define it's own interface, but does assert that it implements some interfaces that are defined by the framework. So it seems that it is not necessary to define the inteface of your product to make it work, but still meaningful to assert that it implements some well-known interfaces. The Zope Developer's guide does not actually say that you must define interfaces to make your product work. It just says that doing so will make it easier for other people to understand your products. If that is the sole effect of using interfaces, it is just for documentation, then. Am I right? -- Hideo writing from Yokohama Japan.

Equivalent of __of__ in Script (Python).
by JoseLuis de la Rosa Triviño 08 Nov '05

08 Nov '05

Hello, I'm a newbie in Zope and I'm trying to do this in a Script (Python): tmp_user.__of__(context.acl_users) However, this produces an error as: "__of__" is an invalid attribute name because it starts with "_" Does anybody know how could I use __of__ operator in this script or an equivalent to it? Thank you very much.
