- Zope - Zope lists

external search engines (altavista, etc.)

I have just joined the list, but I have been reading about Zope for a while now. I think this package is cool! I also like the neat packages that were announced today. Can search engines such as AltaVista mine the information out of a Zope website. I have seen responses to other questions that there are ways to use a search engine to search a Zope website, but can the commercial laces search the website. It would be nice for other places to know about things in your website, unless you want it to be private. Clarence T. Pate

Newbie: Problem with Zserver
by Thomas Weiner 16 Jun '99

16 Jun '99

After spending some hours to decide if I should continue with apache or start with zserver, I began with Zserver. My problem is the following traceback occuring when I call http://localhost:9673 Unhandled exception in thread: Traceback (innermost last) File "D:\Programme\Website\Zserver\PubCore\ZserverPublisher.py", line 92 in __init__ publish_module< TypeError: unexpected keyword argument: request I'm using Zope 1.10.3b1 on Win NT and I've installed the latest version of Zpublisher in the lib directory. Any hints what I missed here? TIA Thomas -- fon: ++49 (0)40 42878 3781 fax: ++49 (0)40 42878 2728

Is this even the right list to > suggest this > heresy or should I strap on the asbestos underwear and wander > over to zopedev? I'll comment first on the multiline statement. Let me reinforce the idea that The Zope Way is to separate presentation and logic. While we should have some kind of object that better deals with logic, I don't think there will be much sympathy for creating something that looks like ASP or PHP. Let me limit the conversation back to your subject line: <% vs. <!--# The latter was originally chosen to be like the dominant syntax at the time (SSI) and to be "legal HTML". I think the latter has proven to be total bunk, as almost no DTML Documents are valid (they get nearly everything from the fragments of standard header and footer). What are some reasons to consider changing from the SSI syntax? o It's hideous, cumbersome, and everybody hates it o No tools support editing it o It isn't conformant with the direction of HTML o Any others? Let's evaluate the situation in light of these. It's Hideous ------------ Yes. Tool Support ------------ The SSI syntax just happens to enjoy nearly zero support out there. Things like Netscape Composer, Dreamweaver, and Emacs HTML Mode just can't be convinced to handle it nicely. Does anyone view this issue as important? Future of HTML -------------- What role does SSI play in the future of HTML? Zero. Of course, neither do any of the alternative syntaxes mentioned previously. Thus, I'd like to list some requirements for a future syntax: 1) Within reach of "content managers". I won't budge on this one. I think XSL will have a role in Zope, but *NOT* as a DTML replacement. 2) Reasonably close to DTML. The current DTML accomplishes some level of functionality. While some small amount might not be permitted in some change, or might be permitted in a clumsy way, there should be a reasonable match. 3) Coherent with the HTML future. We have a choice: invent a syntax and, one by one, support every web authoring tool. Alternatively, we can stick to standards and wait for them to support it. Proposal -------- _If_ these were the requirements, then I think a reasonable proposal is XHTML: http://wdvl.com/Authoring/Languages/XML/XHTML/ http://www.w3.org/MarkUp/#future XHTML reworks HTML as an XML-compliant language. Most imporantly, you can extend it with new namespaces (like Zope instructions) without breaking the DTD, as is the case with ColdFusion et al. Why? 1) Alledgely it is the future of HTML. 2) Becoming well-formed means the authors can be given hints before saving changes, and Zope can do smarter things with structured data on the server. Why Not? 1) A number of differences with HTML might drive people off. 2) It isn't here yet. 3) Zope syntax might not be mappable into XML. At any rate, I'd love for someone in the Zope community to march off and take a look at this, then make a proposal for how things should be changed. As always, patches are accepted. :^) --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909 ----------------------------------------- The Open Source Zope application server http://www.zope.org/ -----------------------------------------

Zope performance too low ?
by Christian Andreassen 16 Jun '99

16 Jun '99

I guess the subscribers to this list, more or less, like working with Zope. Developing dynamic pages is quick and easy, and code/design integration is very comfortable. However I'm starting to doubt if it's worth it. Some quick benchmarking with apache's ab utitlity gave the following results on my server(50 requests, no concurrency, ab ran on the server machine): Copy of the Zope welcome screen(served from disk): 204.08 requests per second The Zope welcome screen(served from Zope): 14.38 requests per second A page with lots of DTML Code(about 50 lines): 2.68 requests per second Repeating the benchmark gave similar results. How does your Zope perform? Can you live with it? I'm not sure if I can.

Direct SQL-Method traversal
by Stefan Bund 16 Jun '99

16 Jun '99

I have implemented a simple ZSQL-Method (fetch) which takes one argument, a record number (nr). As far as I understand the ZSQL Manual, I should be able to write URL's of the form fetch/nr/<number>/showit where showit is a DTML-Document which can access the result of the fetch query. How do I access this result? I tried to use the column names (like , where shortname is a result column name), but Zope gave me a Key Error. What is the correct syntax to access the result columns of such a query? Stefan.

ANNOUNCE: EXPERIMENTAL DTML Syntax change
by Jim Fulton 16 Jun '99

16 Jun '99

Zope 2.0.0 alpha 2 (and public CVS) includes an experimental change to the DTML parser to allow HTML tags syntax and character entity reference as an alternative to the server-side-include (SSI) syntax. Basically, source like:  <ul>  <li> <a href="//manage_workspace"> </a>  </ul>  to be written as: <dtml-var standard_html_header> <ul> <dtml-in objectValues> <li> <a href="&dtml-URL1;/&dtml-id;/manage_workspace"> <dtml-var title></a> <dtml-/in> </ul> <dtml-var standard_html_footer> This format is provided to overcome some of the problems with the SSI syntax: - It looks more like and fits in with HTML, - It is easier to type, - It is easier to type and slightly less verbose, - It is, perhaps, easier to teach HTML editors how to deal with it. I'm very interested to hear how helpful this is. Do people find this a significant improvement? If people don't find it useful then it will not be included in Zope 2.0 final, and perhaps not in the Zope 2.0 betas. Note: - This format does *not*, in my mind, significantly reduce the desire for an XML variant of DTML. I think there is room for *both* XML and non-XML variants of DTML, if only because sometimes people will need to have DTML documents that are not XML well formed, for example when generating non-XML text. - This does not address the desire for a nicer through-the-web scripting language for Zope. We intend to provide the ability to build Python methods through the web that are as safe (from a security point of view) as existing DTML methods.
