[Zope-dev] DTML Documents == DTML Methods that are anchored?

2000-12-29 Thread The Doctor What

What are the differences between DTML Documents and Methods
internally?  I was just thinking about the problems every new user
(and experienced users, every so often) have regarding DTML
Documents vs DTML Methods.

Aren't they really the same except that Documents are anchored (ie,
don't allow aquisition from the caller, but only from the location
of the Document)?

If that is true, couldn't they be simplified as a (example name)
DTML Object that had an "anchor" flag?

Just a thought.

Ciao!

Re: [Zope-dev] DTML Documents == DTML Methods that are anchored?

2000-12-29 Thread matt

You should look through the mailing lists  there is generous amounts of
answers to this.  For me the two sit philosophically linked in the acquisition
model.  Acquisition is partially about actions working in environments, with the
environment decribing the quality of the result.  You can think of a DTMLMethod
as an action, who itself has no substrate, i.e. properties, and  DTMLDocuments
as substrate, i.e. it contains properties etc, for example background colour,
types of animals, whatever.  One can then throw a method around into different
environments, i.e. call it on documents, and one will get a result that is
dependent on that environment(document).   It is also nice that environments can
acquire from their surrounding too, so you should think of acquisition in
DTMLDocuments as been for more and more global properties as one moves out, eg:
a company logo.  Whereas acquisition for a method is to actually acquire an
environment to work in. 

Well that's the way I view it, and it helps.

Matt

[Zope-dev] PythonScripts

2000-12-29 Thread Dieter Maurer

I looked at ZopeCVS's PythonScripts.
I mostly like it -- with the following exceptions:

 * Namespace binding

   It does not yet work, apparently:

 In DTML, I have:

   dtml-call "REQUEST.set('a','a')"
   dtml-var pyscript

 in PythonScript "pyscript":

   return _['a']

 and I get: "KeyError: a"

   
 * Try it

   It is very nice, that such a "try it" exists!

   However, as I am in Python, I would like to use
   Python expressions as argument values.
   Currently, the values are treated as strings.

   Default argument values are displayed as part of the
   argument name. If the values in the "try it" tab
   were Python expressions, the default values should be
   used to preset the value fields.


 * Preventing creation of large sequences

   Apparently, you try hard to prevent the creation of large
   sequences. For a malicious user, it is however quite
   easy to counter you measures: either with a "while" loop
   or with a nested sequence repetition.

   To make it safe, you would probably need to limit
   the total complexity of all objects (together) that
   are created in the script (or other scripts called by
   this one).

   Alternatively, you could document that various
   security issues remain, if PythonScripts are made
   editable through the web.


 * Import control

   I know that I can control what modules (and names) can be imported
   in PythonScripts by providing an
   
__access_to_unprotected_subobjects__

   definition *in the* module.

   However, this is a global control affecting all PythonScripts
   in an installation. I see the demand for more
   localized control, e.g. that a script not editable through
   the web should import modules that are not safe for
   use by anonymous users.

[Zope-dev] HiperDom-0.4.0-DC released

2000-12-29 Thread Martijn Pieters

Hi all,

I created a special release of HiperDom 0.4.0 (versioned as 0.4.0-DC),
with fixes and additional features. This release is ment for
experimentation with new features added by Digital Creations, and we'd
appreciate feedback on these.

The README attached to this email lists all differences.

You can download the release from:

  http://www.zope.org/Members/mj/HiperDom

Note that all fixes to HiperDom problems have been checked into the
HiperDom CVS tree, a future release of HiperDom will include these fixes.

This is the Digital Creations' release of HiperDom 0.4.0. Differences with the
Hiperlogica release are listed below. This release depends on Zope 2.2.5 for
correct XHTML output of base and image tags. This release is ment for
experimentation with new features added by Digital Creations.

HiperDom is a new template system for Zope, based on XML and DOM. It depends
on the PyXML library, version 0.6 or newer. Consult the HelpSys for info on
using HiperDom Templates.

The "official" HiperDom homepage is at
http://www.zope.org/Members/lalo/HiperDom where you will also find the
HiperDom Wiki (the "official" place for discussion, bug reporting and
embrionary documentation).

Discussion about the development of HiperDom takes place on the "HiperDom
Wiki":http://dev.zope.org/Wikis/DevSite/Projects/HiperDom.

Differences with the Hiperlogica 0.4.0 release:

  - The calling interface has been refactored; HiperDom templates now behave
exactly like DTML Documents. This fixes the trailing slash problem in
base tags inserted into XHTML documents.

  - Inclusion of non-callable objects (like Image objects) has been fixed.

  - Names can now also be paths, so you can include references to objects
normally not in the acquisition path. Example:: 

  div hdom:text="images/header.gif" /

  - XHTML output of empty elements will include an extra space before the
slash to ensure compatibility with older browsers.

  - A new directive, 'call', allows calling of objects without including
their return values. This is especially suitable for methods that
manipulate the RESPONSE headers or have other side-effects.

  - A new directive, 'include', allows inclusion of other HiperDom templates
into the DOM at render time.

  - The DataObject object is not included in this release.

  - Some non-relevant files have not been included (exemplo_pt.html and
HiperDom.latte).

Issues with this release can be listed on the "ImplementationIssues
page":http://dev.zope.org/Wikis/DevSite/Projects/HiperDom/ImplementationIssues.

Feedback is greatly appreciated!

Re: [Zope] How to make two racks work under one specialist?

2000-12-29 Thread Steve Spicklemire


Hi Dirksen,

   I think the problem you are having has to do with using 'getItem'.

From the SkinScriptSyntax Wiki page:

"If the RESULT is NOT_FOUND, the search for the attribute value falls
through to the next declaration (or attribute provider if the SkinScript
is finished). If there is an OTHERWISE LET clause, the assignments given
there are computed and cached for the remainder of the (sub)transaction..."

This is meant to work automatically for "WITH QUERY ... COMPUTE" scripts,
but in your case the RESULT was _.None, so the test for NOT_FOUND
didn't work. I think you could in principle set up a chain of 
attribute providers:

WITH Deliverables.getItem(self.id) COMPUTE theStandInObject=RESULT or NOT_FOUND

then

WITH self.theStandInObject COMPUTE name OTHERWISE_LET name='not availble'

so that if RESULT is _.None from Deliverables.getItem, then the
'StandIn' will be NOT_FOUND and the COMPUTE will fall through to
the 'OTHERWISE LET' clause. However I don't think this works well when
the existance of the virtual object in the Rack depends on 'theStandInObject'
being found if theStandInObject is NOT_FOUND then the Rack returns
_.None and you're out of luck. Here's a thought...  what if you put a 
'dummy' object somewhere accessable and did this:

WITH Deliverables.getItem(self.id) COMPUTE theStandInObject=RESULT or theDummyObject

then you could set all the attributes of theDummyObject to be whatever you
wanted  and you would never get a RESULT of NOT_FOUND.

[Zope] Re: [Zope-PTK] Example activity-explicit workflow system

2000-12-29 Thread albert boulanger


   I am very interested in a general, fairly full featured  workflow system
   on top of Zope as opposed to using an external workflow product for a
   fundamental reason. While one could come up with a way of getting what I
   need with an external system, it would be messy. I need workflows to be
   explicit and versioned. We make use of ZODB to version content that end
   users generate. We don't make use of Zope's versioning but use or own
   hierarchical version tree which is easy to do in Zope. End users
   generate new workflows and revisit  past workflows. The user sees this
   versioning as notebook pages using a scientific notebook metaphor.

   It is much cleaner to use ZODB and ZPublisher to do all this instead of
   having a version tree in Zope and a bunch of correspondences to outside
   objects in an external workflow system. Thus,  there is a lot of value
   in having a fairly general workflow system whose representation and
   publishing uses ZODB and ZPublisher.

By the way, if there are other folks interested in such a workflow
system let me know. We may just bite the bullet and build one. I have
who will do most of the coding in mind. What will be produced is a
Zope-based workflow system with a java thin client visual workflow/dataflow
editor. Right now I do not have the funding but folks with resources
could speak now ;-).

Hmm... well, this seems like a good Fishbowl project for me.

Basically, that code shouldn't be tacked on the end, the error message
should be generated by the standard_error_message entirely and not at
all dependent on whether or not Zope is running in Debug mode. It's not
a big change (maybe 1hrs work?) but, like you, I can't remember where
the code lives.

Almost related, how about in the same project changing the hard coded
errors for security (and anything else like that) so that they use the
nearest standard_error_message up the tree?

Can't be more than a coupla person-days work... maybe DC has some

  But when I try to add an instance of this metatype, I still see the

  Is this a bug?  Or is the some other location where I also need to
  change this info?
New Meta Types must register with Zope to be available in the
dropdown list.
Apparently, this registration is not changed when you modify
the meta type -- a bug.

File a bug report into the collector.

I would expect, the bug will get a low priority.
Thus, if its fix is essential for you, you may look at the code
and fix it yourself. A patch for the collector would be great
in this case.

[Zope] Slow response with 2.2.5

2000-12-29 Thread Stephen Simmons

Hi Brian,

I have noticed a problem with 2.2.5b1 running under Win98. The ZServer seems
to wait for 5 seconds or so before serving each page. My fresh installation
of 2.2.4 has no noticable delay.

To duplicate this, go to a Windows 98 machine and:
 - Install Zope-2.2.4-win32-x86.exe and start Zope
 - Try http://localhost:8080 and see the Zope welcome screen appear almost
instantaneously
 - Shutdown Zope
 - Upgrade to 2.2.5 by installing Zope-2.2.x-to-2.2.5b1-win32-x86.tgz then
starting Zope
 - Try http://localhost:8080 and wait for 5 seconds for the Zope welcome
screen to appear

This was observed on a brand new IBM Thinkpad T21 (700MHz PIII, 128MB)
running Win98SR2 while not connected to any network (No cable modem while on
holiday!).

Stephen

[Zope] Zope vs. Enhydra

2000-12-29 Thread corey


I know, I know -- total flame bait...

But really, has anyone had any experience with the *other*
open source Web Application Server, Enhydra?

I just "discovered" it the other day while writing an 
introduction to Zope for my co-workers, as we're about
to embark on a serious new development project.

At any rate, after already being *highly* impressed and
sold on Zope - I ended up spending a little time at
www.enhydra.org and became more and more enthused. I'm
currently downloading it to give it a fair chance -
but I was wondering if anyone else here has happened
to have already given it a review, and if so, could
you relay some of your findings/opinions?

I've yet to stumble across any mention of Enhydra in
any of the Zope documentation/introductory material or
even yet on this list. I'd be interested in hearing
any testimonials from Zopistas.

Thanks for any input!


Beers,

Corey

Re: [Zope] Zope eating CPU/RAM - how do I find the culprit?

Are you using ZSQLMethods by any chance?

Yes, why? (I think I've fixed /this/ problem, but if ZSQLMethods will
cause similar behaviour I'd like to be prepared :-))

Re: [Zope] Slow response with 2.2.5

 Hi Brian,
 
 I have noticed a problem with 2.2.5b1 running under Win98. The ZServer seems
 to wait for 5 seconds or so before serving each page. My fresh installation
 of 2.2.4 has no noticable delay.

Interesting. I was just going to comment about the performance
IMPROVEMENT that I got on RH Linux with the upgrade to 2.2.5b1

Re: [Zope] Zope vs. Enhydra

2000-12-29 Thread Terrel H. Shumway

Flame bait? Catch this:
I have recently been reaching the disillusionment phase with Zope, so please
take it all with several grains of salt.

I happened upon an article in the ArsDigital Systems Journal that I thought
was a fairly neutral review of Enhydra. 
http://www.arsdigita.com/asj/enhydra/index.adp

The more thought-provoking part of the article was a reference to a fairly
disparaging view of application servers in general.
http://www.arsdigita.com/asj/application-servers

What got me to ArsDigita was AMK's Zope frustrations.
http://www.amk.ca/python/writing/why-not-zope.html
(BTW, some of these issuses are being addressed.)

Which also lead me to Chuck Esterbrook's musings 
http://pywx.idyll.org/advocacy/why-not-zope.html
http://pywx.idyll.org/advocacy/why-not-zope-2.html

Chuck Esterbrook created webware as his answer to Zope's limitations and
complexity.  http://webware.sourceforge.net/

Titus Brown advocates use AOLserver and Python (instead of TCL)
http://pywx.idyll.org/advocacy/

IBM developerworks has a couple of Enhydra articles (which I have not read yet)
http://www-106.ibm.com/developerworks/library/enhydra.html
http://www-106.ibm.com/developerworks/library/w-friend.html?dwzone=web


In summary: Don't build what you don't need -- do the simplest thing that could
possibly work.  Evaluate potential solutions in terms of business value to 
YOUR customers, not in terms of market hype.  


  HTH
