SMB validation?

Has anyone managed to come up with a User Folder product that will work under UNIX that will allow you to use a list of NT domain users as a Zope userlist? I know about the NTUserFolder product, but it only works under NT. I've downloaded the smb validation wrapper for Python, and I'm about to (try) to hack the etcUserFolder product into an SMBUserFolder using this library, but before I do so, has anyone already done it? If so, are you willing to release it?

Alternatively, you could put 'username' in the argument list, then call it with "sqlmeth(username=AUTHENTICATED_USER.getUserName())" Anthony

Zope 2 lacunae
by victor＠idaccr.org 09 Sep '99

09 Sep '99

I've installed Zope 2.0.0 on my win95 machine, and am now trying to develop a simple Zope Product API, and am following the tutorial "Approaching the Zope Product API". However, I'm running into a few fundamental problems which would have been helped by entries in the documentation: 1. Page 6 suggests the following sort of inheritence: class Poll( Acquisition.Implicit, Persistent, AccessControl.Role.RoleManage, OFS.SimpleItem.Item): however, it doesn't say what import statements to use. When I tried the "obvious" ones: Acquisition, Persistent, AccessControl and OFS they don't work. In fact when I searched around and found lib/Python/Persistence there's nothing in it (but a comment). 2. The version of Test.py distributed with windows appears to be missing the following crucial lines (which I found in z2.py). Without them scripts running under Test can't find the modules. # Have to fiddle the path for win32 binary dist. # to ensure the bundled python libs are used. swhome=r'D:\MyHome' import sys sys.path.insert(0, '%s/lib/python' % swhome) sys.path.insert(1, '%s/lib/python1.5' % swhome) sys.path.insert(2, '%s/lib/python1.5/plat-win' % swhome) sys.path.insert(3, '%s/lib/python1.5/win32' % swhome) sys.path.insert(4, '%s' % swhome) Someone PLEASE update the documentation, so that I and others don't need to waste a lot of time hunting around to see where these things are.

how to print error stack trace
by Jay, Dylan 09 Sep '99

09 Sep '99

I am trying to put in some code to automatically mail me when ever a zope error occurs. However I want to include the python stack trace in that mail. This doesn't seem to be a variable included in standard_error_html but rather automatically tacked onto the end of this document. How can I include this stack trace?

I think I have it installed right. Where do I "call" it from ? Please Help. I have another question about apache and Zope. I have restricted access to /cgi-bin/Zope/Zope.cgi to lock down the management screen. How do I let EU view my web site. I tried with setting the directive location to /cgi-bin/Zope/Zope.cgi/manage and this lets you into the Zope site, but when I go to /manage and enter the password I get one frame and and error message. Can someone help me get this set up right ? -- Windows 95/NT - 32 bit extensions and a graphical shell for a 16 bit patch to an 8 bit operating system originally coded for a 4 bit microprocessor, written by a 2 bit company that can't stand 1 bit of competition.

Storing a list of numbers in a property
by Chris Walter 08 Sep '99

08 Sep '99

Hi Zope-sters, Can anyone tell me how to store a list in a property in a property_sheet in a zclass instance? What I want is to have a property (lets say its called grades). So I can <dtml-with student> <dtml-in grades> Homework: <dtml-var sequence-item> </dtml-in> </dtml-with> Which should loop through the grades list and print them out. The thing is: I can't figure out what kind of property to use. If I use a string and stick 23, 45, 67 in it then I get an error that you can't use strings with an dtml-in. I tried using "token" and "lines"(I'm not actually sure what these are). This worked but I was unable to math with the entries. I get the error: number coercion failed When I try to do something like this: <dtml-let value=sequence-item> <dtml-call "REQUEST.set('total',total+value)"> Any hints? -Chris Walter walter(a)budoe.bu.edu

The Redirector product is what I'm using and it doesn't do that. It redirects only objects in one folder not and entire subtree.

Re: [Zope] CONNECTION POOLING/CONCURRENT DATABASE CONNECTIONS
by Christopher Petrilli 08 Sep '99

08 Sep '99

> Question: > > Can ZOPE handle multiple database connections or connection pooling? Yes and no. There, that was easy, yes? :-) What this means is that each thread of the application server (normally 4) will have it's own set of database connection objects instantiated. Whether the back-end actually serializes it or not is a separate question, largely dependent on thread-safety of client libraries. You can of course have multiple database connections to different databases as well. Connection pooling is a much harder concept to deal with. I'm not sure how this applies to Zope, and honestly if it would GAIN anything other than the management of the number of connections to Foocle database. Right now, there is no way to do that other than to control the number of application threads---which isn't ideal, but nobody has actually SHOWN a problem in real world situations. Does this answer your question? Chris -- | Christopher Petrilli Python Powered Digital Creations, Inc. | petrilli(a)digicool.com http://www.digicool.com
