Could this be the culprit? We have had that behaviour when we used an old DCOracle to connect to an Oracle 8.1.6 server: The oracle client library cause a memory corruption that brought our Zope down about every 5 to 10 minutes. Our problem disappears after we installed a newer DCOracle. Dieter

Secure Python Script
by Gerald Gutierrez 08 Feb '01

08 Feb '01

I think there was brief mention of something like this a while ago. A complement to the current PythonScript (I think that's what it's called now), where you are able to script objects in Python, but differs in that there are no restrictions on what can be imported and what can be executed. It can be made secure by only allowing very few people to be able to manipulate one, like only those in the Manager role (who can do just about anything anyway). I think this can be a real bonus to those web applications that are more than just a "picture gallery" or a "message board", like those that are logic intensive and maintain client state (like a game). The scripts can effectively become the "business logic layer", and eliminate the need to do file-system level scripting. I believe this was one of the goals of Zope -- to do everything through a web browser. What are the pros and cons of this?

LocalFS Error on zope 2.3
by Ed Colmar 08 Feb '01

08 Feb '01

Hi all I just installed a zope 2.3.0 on a soon to be production server, but I am having some difficulty with LocalFS. It installs fine, but when I add an instance to a folder I get an attribute error, with value _local_path Then I am unable to access any of the other items in the folder... Good thing this is a fresh box, that can easily be wiped out... Thanks for any hints! Here is the traceback: Traceback (innermost last): File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_main) File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_main) File /usr/local/zope/lib/python/Shared/DC/Scripts/Bindings.py, line 324, in __call__ (Object: manage_main) File /usr/local/zope/lib/python/Shared/DC/Scripts/Bindings.py, line 353, in _bindAndExec (Object: manage_main) File /usr/local/zope/lib/python/App/special_dtml.py, line 236, in _exec (Object: manage_main) File /usr/local/zope/lib/python/DocumentTemplate/DT_In.py, line 711, in renderwob (Object: objectItems) File /usr/local/zope/lib/python/DocumentTemplate/DT_With.py, line 146, in render (Object: sequence-key) File /usr/local/zope/lib/python/DocumentTemplate/DT_Var.py, line 271, in render (Object: bobobase_modification_time) File /usr/local/zope/lib/python/Products/LocalFS/LocalFS.py, line 979, in bobobase_modification_time (Object: localfiles) AttributeError: (see above)

Re: [Zope] Can't start Zope (Python 2.0 , BSDI 4.0 , Zope 2.3.0b3) => ImportError: cannot import name DateTime

Hi Emmanuel, This question is better posed to the main Zope list (the Zope-Dev list is for Zope development issues rather than installation issues). Did Zope successfully compile extensions when you ran "python wo_pcgi.py"?

You can use the "_.max" function to determine the highest modification time of all objects your are interested in; something like: <dtml-var "_.max(bobobase_modification_time(), news.bobobase_modification_time(), standard_html_header.bobobase_modification_time(), )"> Dieter

Write an external method that called the > applet and then call the external method? Someone else already suggested to put the class into a "jar" archive. Do that if you can. If not and you are using Zope 2.3, then you can look at PythonScript. It allows you to intercept subpaths, analyse them and do something sensefull with them. In your case, they could translate '$' into '_' and access the object in a nearby folder. Dieter

Looks like a product is no longer compatible with the new Zope version. Usually, you get a traceback that helps to identify the affected code. Dieter
