Knotmail product?
by Tim Potter 06 Aug '99

06 Aug '99

I was just wondering whether there were any plans to release Knotmail as separate product? It was tantalisingly alluded to in the animated GIFs in the portal toolkit technology demo but doesn't seem to appear anywhere else. Are NotMail and Knotmail releated somehow?

We just got clued into http://www.openclassroom.org; they are working on setting up a Linux distribution and software toolkit for educational purposes. And their site is Zope powered... jon Jonathan Corbet, Eklektix, Inc. corbet(a)eklektix.com

Our plans for XML are MUCH bigger than just a tacked on syntax, and XMLDocument is just the beginning of what you'll see in the coming months. We specifically avoided using an XML namespace syntax. As for whether it will change, I SERIOUSLY doubt it, as: * It's already been adopted by internal projects * It's been adopted by OTHER projects * Documentation is being updated to reflect this There's no huge gain to go to <z-foo> rather than <dtml-foo> other than a few saved characters. The larger gain was moving away from SSI syntax, because this has allowed us to teach the syntax to editors like Alpha and GoLive. This discussion should have happened a month ago before we committed the new syntax out of "experimental" stage, but it is no longer experimental. As for new renderers, well, *personally* I think there are too many syntaxes as it is:  <dtml-var foo--> %(foo)s or some such :-) Over the long term, I suspect that the SSI syntax will be deprecated, but not until we can provide a good program to convert everything to the new syntax.

WARNING: Zope 2.0b2 considered harmful to ZClasses
by Christopher Petrilli 05 Aug '99

05 Aug '99

Gang, Well, this is unusual, but unfortunately ZClasses seem to be largely broken in beta 2. How this happened we're not sure, and we sat and tried to fix it as quickly as possible, but the problem seems to be quite deep, and not due to any recent single change. What this means is that if you're using ZClasses you shouldn't even *think* about using Zope 2.0b2. This would be a bad idea. To prevent problems, I'll be removing it from the web site. Sorry for all the problems, and thanks to those who noticed. Chris -- | Christopher Petrilli Python Powered Digital Creations, Inc. | petrilli(a)digicool.com http://www.digicool.com

The new DTML syntax
by Alexander Staubo 05 Aug '99

05 Aug '99

Am I the only one who does not take particularly kindly to the new DTML syntax? Well, I guess I might be. :) Before you bring forth the lynching implements, though, hear me out. In my opinion the number one problem is that the word "dtml" detracts from readability (as does the fact that the new syntax is visually less distinguishable from HTML or XML, but I guess that as we're dealing with SGML-like markup languages we can't really avoid that). When I think "if", I want to type "if", not "dtml-if", and consequently I typically end up writing "if", backtracking a bit, typing "dtml-" and then going on from there. That's just me, I guess. But the point is, the inclusion of "dtml-" spins my mind through too many connotations. If I had to type "html-" before every HTML tag, the same thing would happen. It would be a pain. Since control characters (<, >, :, # and so forth) do not carry the baggage of mental associations, they are more efficient, and that's why the old "<!--#" sequence still comes easier to my mind than the new syntax. Another, possibly more powerful argument is that the new syntax is essentially backwards: The actually "command" or "directive" doesn't start until 7 characters into the tag ("<dtml-"). To match one dtml-if against its closing tag, the mind must visually match a whole 7 characters ("dtml-if"), which is awkward. More than that, psychologically a sequence of characters such as "dtml-if" is much less efficient for pattern matching than just the sequence "if", especially if we consider the multitude of DTML keywords: They all share the common prefix "dtml-", making them variations of a spelling rather than separate, mind-sortable entities. The fact that the closing tag slash -- as in "</dtml-if>" precedes the "dtml" part actually _forces_ your brain to process the whole string, as opposed to just honing in on the "if" part. I don't know about you, but my mind sifts through a list such as if in var else unless sqltest call must faster than dtml-if dtml-in dtml-var dtml-else dtml-unless dtml-sqltest dtml-call Imho, Cold Fusion's CFML syntax does one notch better than DTML because it only devotes two characters ("CF") to distinguishing Cold Fusion tags from other markup, so you have keywords such as "cfquery", "cfoutput", and so on. Easily recognizable, short, sweet, easy to type. On the other hand, it uses a proprietary syntax for in-place variable insertion (eg., "#Name#" inserts the variable Name), so it's not all bliss. While I realize this stuff is somewhat subjective, from a technical viewpoint my opinion is that we're not there quite yet. Bring on the pitchforks and torches. :) -- Alexander Staubo http://www.mop.no/~alex/ "It has taken the planet Earth 4.5 billion years to discover it is 4.5 billion years old." --George Wald

Hi. I just installed Zope on another machine after using it for a while on another machine. It installed fine, but when I do ./start to start the services the following is what I get: [grace@hsu55461 zope]# ./start ------ 1999-08-05T20:49:00 PROBLEM(100) ZServer Computing default hostname ------ 1999-08-05T20:49:00 INFO(0) ZServer Medusa (V1.10) started at Thu Aug 5 13:49:0 0 1999 Hostname: hsu55461.humboldt.edu Port:8080 ------ 1999-08-05T20:49:00 INFO(0) ZServer FTP server started at Thu Aug 5 13:49:00 19 99 Authorizer:None Hostname: hsu55461 Port: 8021 ------ 1999-08-05T20:49:00 INFO(0) ZServer Monitor Server (V1.5) started on port 8099 After this I can't access anything on port 8021, 8080, or 8099 with my browser. Any ideas? It seems to hang after the last line. Ryan

Serious bug in beta 2
by Kevin Dangoor 05 Aug '99

After installing beta 2, I tried adding some ZClass instances, but I was unable to add any. Then I tried making a test Product with a test ZClass using the default data.fs. Here is the traceback I get: Error Type: AttributeError Error Value: foo Traceback (innermost last): File C:\Program Files\Byproducts\lib\python\ZPublisher\Publish.py, line 209, in publish_module File C:\Program Files\Byproducts\lib\python\ZPublisher\Publish.py, line 179, in publish File C:\Program Files\Byproducts\lib\python\Zope\__init__.py, line 199, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File C:\Program Files\Byproducts\lib\python\ZPublisher\Publish.py, line 165, in publish File C:\Program Files\Byproducts\lib\python\ZPublisher\mapply.py, line 154, in mapply (Object: TestClass_add) File C:\Program Files\Byproducts\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: TestClass_add) File C:\Program Files\Byproducts\lib\python\OFS\DTMLMethod.py, line 145, in __call__ (Object: TestClass_add) File C:\Program Files\Byproducts\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: TestClass_add) File C:\Program Files\Byproducts\lib\python\DocumentTemplate\DT_With.py, line 133, in render (Object: TestClass.createInObjectManager(REQUEST['id'], REQUEST)) File C:\Program Files\Byproducts\lib\python\DocumentTemplate\DT_Util.py, line 315, in eval (Object: TestClass.createInObjectManager(REQUEST['id'], REQUEST)) File <string>, line 0, in ?
