Restricting URL access to objects that are not complete web pages
by Stephen Simmons 21 Sep '00

21 Sep '00

After reading the Zope lists for a couple of months to struggle up the Zope learning curve, it's time for my first question. I want to serve web pages build up from a database of document components. Zope's object-based subsystems should be completely hidden so that the only objects accessible over the web interface are complete, well-formed HTML web pages. For the sake of simplicity, suppose we have three types of components, web pages, articles and sections. These components obey the following 4 rules: 1. Web pages operate just like a DTML document, where the articles and sections from which it is built are specified via dtml-var. The page definition starts with standard_html_header and _footer (or similar) to create nice HTML output. 2. Articles are primarily meant for inclusion within a web page so that they are displayed in a browser by specifying the URL of their containing web page. However if an article's URL is specified, the article automatically gets wrapped in an HTML template. 3. Sections are only used as building blocks for other documents so it must not be possible to retrieve a section via a URL. 4. Similarly, standard_html_header and other methods/objects not meant to be a standalone web page should not be accessible via a URL. My thoughts were to use an html_header that tracks how deeply components are nested so that inner components turn off the page wrapper. This achieves 1 and 2. This also achieves 3 if sections raise an exception if their page wrapper is not turned off. But 4 was where I got stuck. I want to use the full magic of acquisition when assembling web pages from components within a page, but prevent acquisition from returning other objects via URLs. So mypage in http://myserver:8080/myarea/mypage is able to find standard_html_header by acquisition but http://myserver:8080/myarea/mypage/standard_html_header gives a not-found error. Any suggestions? Something involving permissions/roles? Hacking before_bobo_traverse()? Something simpler? Thanks for any assistance!

FSF about Zope and GPL'ed components

In this case, the whole larger program falls under the terms of the GPL. This is a real problem, since the license of Zope is incompatible with the GNU GPL. This means you can't legally distribute the system. > If the GPL applies to the entire work, the resulting question is: How do I > separate my work inside a Zope-based application from GPL'ed pieces to > prevent this from happening? Or do I have to rewrite the GPL part? You cannot legally combined GPL'ed software with Zope. You'll need to rewrite the Zope part and release the software under a license compatible with the Zope license, or you'll need to convince the developers of Zope to make their license compatible with the GPL. (In the latter case, the whole system would be covered by the GPL, so you'd still be bound by the terms of the GPL---the only difference would be that it'd be legally to distribute the system, since Zope wouldn't be GPL-incompatible anymore.) > Everything would be easy, if we would only be talking about programs like > Emacs but Zope products/modules/components/whatever look more like > libraries to me... Regardless of whether or not a program is a library, when you combine it with GPL'ed software to form a larger program, all of the code in the system falls under the terms of the GPL. -- Bradley M.
