My first response: Does Zope need to run on port 80 at your site? If you can run it on a port >1024, you will have a much smaller security hole. Regards, Jeff Bauer Rubicon, Inc.

If we can do a good job of capturing the requirements, then documenting the interfaces for managed content, then the project can be used pretty widely.

OK, should you choose to jump in, can you provide a summary of the features and limitations of Mason? --Paul

- FYI: Addition to roadmap -- Zope Classes
by Paul Everitt 19 Jan '99

19 Jan '99

Oops, I forgot a pretty important one: Zope Classes out to see the light of day in the next two months. Zope Classes allow you to build a collection of Zope objects that are the constructors for new objects. Users will see a new item that they can add to their folders, but the "class" is really an instance in the object database. "Class" behavior is managed by forms and objects in the Zope Control Panel, which change the state of all instances of that Zope Class. How can this be used? Say I want to create a simple Feedback application. I would create a Folder that contained an addFeedbackForm Document object that collected information from the user and an addFeedback Document that took the information, emailed it to the administrators, and stored it as an entry in the Folder. I might also create a little management interface Document that let me set some central properties, browse the feedback items, and compute some totals. I would also create some special forms that collected the information for new Feedback Folders and set the initial state. I could then package this Folder up as a Zope Class and make it available to all Folders in the system (or ship it to someone else's system). People would now have "Feedback Folder" as a list of possible things they could add. But unlike Zope Products, there is no lib/python/Products/ directory on the filesystem with the Python code. All the logic is handled by DTML scripting from objects stored and managed in the object database. Moreover, new Feedback Folders are instances of a Zope Object (a Python instance), not a Python class. Thus, "class" information has a nice GUI in the Control Panel for changing central information, such as the email address for feedback information. Also, you can change the global look and feel of pieces of content by changing the Document in the Control Panel. Of course I might have this all wrong, and Jim will correct me :^) --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909

- Using "tree" with an object
by Gabe Wachob 19 Jan '99

19 Jan '99

OK, another question. I have an XMLFile (derived from Document). It has a domtree attribute which contains the XML document as a DOM tree. I have a index_html.dtml file which is displayed as the default view. I would like to use the  construct to interactively view the XML files (as trees), hiding and displaying structure as the user pleases. I was going to do this by hand, but I thought using the  construct would be kewl. Well, I'm having more problems with DTML. How do I use the  construct with the object's domtree attribute (that is, with any object referred to by my Document-subclasses XMLFile)? I've tried just inserting "domtree" in the name attribute (no success) of tree, I tried "self.domtree" (no success), I've tried "_.getitem(document_id, 0).domtree" (no success), I've tried the below (no success):    I really don't know what I'm doing -- the documentation on how to refer to objects contained within a Document (for example) in the context of DTML seems incomplete. Finally, how do I write my own HTML response forms? Do I *have* to use MessageDialog? Also, where are MessageDialogs documented?? If I don't have a REQUEST or RESPONSE as an explicit parameter to my methods, what does ZPublisher do with the stuff returned by a published method? Am I asking too much for all this documentation? -Gabe

PCGI info files will override environment variables, a feature which has a potential for misuse. The pcgifile sanity checker will issue a warning to the unwary.

- A little problem...
by Magnus Lie Hetland 19 Jan '99

19 Jan '99

I don't know if this might be of general interest, but I would greatly appreciate any help. I am at the moment trying to set up a Zope server on a machine on which I don't have root access. The only problem is getting it to run on port 80. The admin mentioned something about making a suid root c-program that bound to- and turned over port 80 to a non-privileged Zope process. (I guess suid-zope would be a *bad idea*, since it's interpreted.) But I don't know how I can hand over a socket like that... Especially not how Zope would handle it... Any ideas? -- Magnus Lie Hetland www.pvv.org/arcadia <arcadia(a)pvv.org>

Of course, cache header management (which Zope currently doesn't do right at all) becomes more important. --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909

- Moving the database...
by Magnus Lie Hetland 19 Jan '99

19 Jan '99

I tried to move the Data.bbb.* files from my old Zope server to my new one (from Solaris to FreeBSD) but it didn't work. I installed TinyTables, which I had installed on the original one, I set all the permissions, but still it wouldn't work. The server just died before I could get anything out of it. When I put back the original database, it worked again... -- Magnus Lie Hetland www.pvv.org/arcadia <arcadia(a)pvv.org>

The solution for me (using ZopeHTTPServer behind Apache) was to tell it explicitly what its SERVER_NAME, SERVER_PORT and SCRIPT_NAME environment variables are, then use them to construct URLs in my DocumentTemplates. Note that since I'm only using ZopeHTTPServer I don't have to worry about incorrect BASE tags showing up in my documents' <head>s.
