ZOPE 2.2.1 Problem
by Steve Williams 12 Sep '00

12 Sep '00

I installed ZOPE 2.2.1 yesterday under Windows 98 to fix a ZSQL authorization problem. After rebooting my machine this morning, when I run ZOPE's start.bat, the DOS command screen comes up, flashes some messages quickly and then disappears, so ZOPE won't start. Running Z2.py in Python gives me the following traceback: >>> Traceback (innermost last): File "C:\Program Files\Python\Pythonwin\pywin\framework\scriptutils.py", line 237, in RunScript exec codeObject in __main__.__dict__ File "C:\Program Files\ZopeHub\Z2.PY", line 554, in ? exec "import "+MODULE in {} File "<string>", line 1, in ? File "C:\Program Files\ZopeHub\lib\python\Zope\__init__.py", line 94, in ? import ZODB, ZODB.ZApplication, imp File "C:\Program Files\ZopeHub\lib\python\ZODB\__init__.py", line 85, in ? import sys, ExtensionClass, TimeStamp, cPersistence, Persistence ImportError: No module named ExtensionClass I've got an ExtensionClass.ref and an ExtensionClass.stx in lib/Python/StructuredText/regressions, but no ExtensionClass.py I have no products installed, other than the ones that come with the distribution and I have no Python extensions.

Re: [Zope] Zope and the GPL poison pill
by Magnus Alvestad 12 Sep '00

12 Sep '00

Just to state my position, I have worked as a professional commercial software developer since 1994. I think the GPL is appropriate for work I do outside customer contracts. [Nils Kassube] | The problem is not that a client who paid for custom development | will get the source. It's the fact that you have to release the | source code of an enhanced GPL'ed component (and possibly stuff | built with it) for everyone else, too. (complete version at http://www.gnu.org/copyleft/gpl.html) -- from the GPL 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, -- These are the most relevant sections. It's pretty clear that you are only obligated to distribute source to the parties you've distributed object code / executable form to. | Another issue is that in a complex object oriented environment | like Zope it's difficult to determine if you only used a GPL'ed | component or "embraced and extended" it. Actually the embrace and extension was a silly Microsoft-joke, the definition in the license text is more verbose: .. a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. .. I don't think a zope site could be defined as a 'work'. -Magnus

You can use "ZopeFind" (see the object reference on zdp.zope.org for a documentation) with obj_expr='_.hasattr(aq_explicit,"your_property")' You will need Zope 2.2.1 as older Zope version have a ZopeFind bug preventing this use.

Xron TypeError revisited
by Dwayne Morrison 12 Sep '00

12 Sep '00

Hello, I posted earlier about Xron 0.0.9 event scheduling woes. One of my stabs in the dark seems to work. I removed the 'this()' parameter entirely and now am able to schedule events via DTML. I also had to add the 'US/Eastern' parameter to the DateTime call to get a current value for DateTime. It was returning 12/31/1969. Xron documentation (works on Zope 2.1.3): <dtml-with "manage_addProduct['Xron']"> <dtml-call expr="manage_addXronDTMLMethod( this(), 'SchedMethodId1', 'Scheduled Method 1 Title', file = 'Content-Type: text/plain\n\nBANG!!!', executeAt = _.DateTime()+14 )"> </dtml-with> Here's what works for me on 2.2.0: <dtml-with "manage_addProduct['Xron']"> <dtml-call expr="manage_addXronDTMLMethod( 'SchedMethodId1', 'Scheduled Method 1 Title', file = 'Content-Type: text/plain\n\nBANG!!!', executeAt = _.DateTime('US/Eastern')+14 )"> </dtml-with> I'd appreciate any insight as to why this works without the 'this()' parameter in 2.2.0. Thanks, Dwayne Morrison dcmorrison(a)tidewater.net

Hi I'm having some strange problems with the RPM version of Zope 2.2.1: it starts, but dies without any message in /var/log/messages. I try to run it by hand, and get these messages: [root@server zope]# ./zserver.sh [root@server zope]# Traceback (innermost last): File "z2.py", line 554, in ? exec "import "+MODULE in {} File "<string>", line 1, in ?

Re: [Zope] 'showREQUEST' or 'show_REQUEST' ?

Steve Alexander writes: > I get an error when I try to add a DTML Method with REQUEST anywhere in > the id. > > Actually, the method gets added, but I cannot edit it. > > I haven't found out why yet. The bad code is in "ZPublisher.BaseRequest.traverse": # Make sure that REQUEST cannot be traversed. if find(path, 'REQUEST') >= 0: return response.notFoundError(path) While the comment indicates that "REQUEST" should not be traversed (probably a good thing to avoid complete confusion inside DTML), the code is a bit generous to ensure this as it forbids "REQUEST" to occur anywhere in the path. Almost surely a case for the Collector. Dieter

Making some DTML Documents catalog aware
by Christian Couder 12 Sep '00

12 Sep '00

Hi everybody, I have a Zope site with many DTML document and I would like to make them catalog aware because I want the web site users to be able to search the site. The web site users are already able to modify the site themselves and this functionality must be kept. I use the debian zope package version 2.1.6-5.2. My first thought was to create a new ZClass that inherit from both the CatalogAware and the DTML Document class but it seems to be quite difficult. First the How-To: DTML Zclass ID Bug Workaround helped a little, but when I try to map some DTML methods to some views in the "Views" tab of my class, no tab for the view are displayed for the class instance. I also searched the news and the documentation and it seems that many people faced some problems when inheriting from both CatalogAware and DTML Document. So now I suppose this is not the best way to solve my problem. Do some people have succeeded in something like this ?
