I'll chime in on Mike's reply... Zope works fine with NES 2.x (yes, we've got customers with it!), NES 3.5x and 3.6x. <SNIP> --Rob

Zope works with any webserver that 1) does CGI, and 2) passes the HTTP_AUTHORIZATION header to the CGI script. Niether NES or Apache do this without modification, Apache must use a rewrite rule, or the new mod_pcgi module, and NES must use an NSAPI plugin which is unsuported. The closed source nature of NES is very limiting. We do have customers who use the plugin, however. > > #2: Do I understand correctly that **every** page is built and served > dynamically?

Every page is served 'dynamicly' in that it is pulled from the object database. However, pages do not need to be rendered if they do not contain any DTML scripting. When a document is added, the DTML is compiled for speed, it is not parsed and compiled on every access. Zope is much faster than traditional CGI solutions for "dynamicly" generating content, since the Zope process is running all the time, there is no fork and exec'ing of an interpreter overhead. Also, I have no benchmarks on traditional file serving vs. serving from the object database, I would venture a wager however that you will not notice it even under heavy loads. Zope 1.x has been proven to do well over a million hits a day on modest hardware, and Zope 2.0 will be able to perform much faster and smoother than that. Given also that it is written in Python and not (god forbid) Java means that it is very cross-platform and can run on every platform that python can run on and that you can compile C python extensions onto. Also, Zope works well in conjunction with a classic file based web server. For intense raw gotta get out as fast as posible static web page serving, you can very easily integrate Zope with a lightning fast server, like Zeus or a highly tuned Apache.

Value of id in sub-sub-DTML-Methods
by Stefan Bund 14 Jun '99

14 Jun '99

I have the following setup: Folder at /Zope/DB: standard_list DTML Method list_bottom_left DTML Method . . . Folder at /Zope/DB/Address: index_html DTML Document list Z SQL Method list_top_center DTML Method . . . Those objects have the following dependencies: o standard_list defines the standard layout for the representation of a (batched) list of SQL results. list, list_bottom_left and list_top_center are some of the sub-documents referenced by standard_list. o /Zope/DB/Address/index_html references standard_list to display the result of /Zope/DB/Address/list. So far so good. When selecting the URL /Zope/DB/Address (or /Zope/DB/Address/index_html), the value of the id DTML-Variable behaves very strange (in my opinion): o within the index_html Document it is 'index_html'. Good. o Within standard_list it is 'index_html'. Also good. o Within list_bottom_left and list_top_center it is 'Address'. What???? How do I find the name of the displayed page? I always thought id should be the value? By the way (I almost forgot), I'm using Zope 1.10.2 Is this a (known) Bug or have I understood something completely wrong? Stefan.

Is it possible to have to separate Zopes (running on different servers) and make them sincronize their object databases ? -Petru

Other web servers?
by Richard R. Morgan 14 Jun '99

14 Jun '99

Hi all- We are attempting to evaluate Zope and and similar products for our intranet. I have been digging through the zope website and can't find the answer to these.... #1: Does Zope work with any other webservers, beyond apache and the included python server? Like Netscape Enterprise Server? We need a solution that works with NES. #2: Do I understand correctly that **every** page is built and served dynamically? Is there a performance issue here, since static html serve the fastest? Much of our content will be static pages, but we need ease-of-use for publishing by non-web persons.

RE: [Zope] Is there any plans to combine harvest with catalog?

I started using it in 1992/93 and we actually fielded some consulting opportunities using it before the group disbanded (most going to Netscape to start the Catalog Server). I thought Harvest was mostly dead? Anyway, having a web crawler index your site has strengths and limitations as have been described here. We at one time had extended Harvest to make it "play nice" with an object system we had created (for employment info), but in the end the two architectures were too disimilar. --Paul

We had a standing offer to ship a copy of the ODMG standard (an expensive little book) to anyone that would make a good faith effort. Someone took us up on the offer about four months ago. Never heard much in reply. We'd _love_, _love_ to see some work on OQL in Zope.

Howdy everybody. I got contacted by a Boston firm that has an immediate need for a small amount of consulting to complete a Zope project. Looks like about three days work, preferably to finish this week.

We are working with ZOPE and Macromedia Generator they work very well together. Generator is a graphics server package that is used with flash. All generator requires is a data set formatted a certain way. Zope is perfect for the Job. The only requirement we have found is that Zope and Generator need to be on the same server. Best of Luck!

I'd like to play devil's advocate here for a moment - can you give me an example of an application where ad-hoc reports on _Zope_ object data are a requirement? Why would you not use Zope's relational database integration tools (SQL Methods, etc.), to deal with this kind of enterprise data? That way any existing ad-hoc reporting tools that work with your RDBMS could be used. > We could view such requirements as a clarion call for another layer of > (refactored) design: perhaps providing hooks to allow the > Zope developer to > tackle the OO<-->RDBMS mapping problem head on would be > useful?

The real point of supporting an abstract data storage in Z2 is to let folks use a backing store that they feel comfortable with (as far as stability support, scalability, availability, etc.), rather than to try to integrate Zope into the relational (or even object/ relational) world. I'm a bit curious what those hooks would look like - I suspect that the more you think about them, the more there will need to be :^) > Breaking the dependency on pickling, > using instead, say, XML > stored as a blob, might be helpful in some circumstances, as well. Is XML stored in RDB tables that much better than pickles? Are there (reporting, etc.) tools that support this, or is it just that XML would be slightly more human-readable? Note that I'm not necessarily against such a thing, I'm just curious what purpose it serves. Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com
