ZMySQLDA broken with Redhat 9?
by hpinson＠indepthl.com 23 Aug '03

23 Aug '03

This is really baffling: I cannot seem to get ZMySQLDA to work on Redhat 9. Here's what is installed: (Zope 2.6.1 (binary release, python 2.1, linux2-x86), python 2.1.3, linux2) MySQL-shared-compat-4.0.13-0 MySQL-server-4.0.13-0 MySQL-devel-4.0.13-0 MySQL-client-4.0.13-0 MySQL-python-0.9.2-1 /var/zope/lib/python/Products/ZMySQLDA version 2.0.8 Here is the traceback: Traceback (most recent call last): File "/var/zope/lib/python/OFS/Application.py", line 541, in import_product product=__import__(pname, global_dict, global_dict, silly) File "/var/zope/lib/python/Products/ZMySQLDA/__init__.py", line 91, in ? import DA File "/var/zope/lib/python/Products/ZMySQLDA/DA.py", line 92, in ? from db import DB File "/var/zope/lib/python/Products/ZMySQLDA/db.py", line 89, in ? import _mysql ImportError: No module named _mysql Is it a path problem? Adding: PYTHONPATH=/usr/lib/python2.2/site-packages EXPORT PYTHONPATH to /var/zope/start does not seem to fix it. Nor does: PYTHONPATH=/usr/lib/python1.5/site-packages EXPORT PYTHONPATH ...which is where I can find _mysql.so as well as the MySQLdb directory. Zope appears not to run at all if I change Zope' python to 2.2, which came with RH9, so I am using the default python that came with the Zope binary. Getting MySQL and Zope to talk on Linux used to be so easy. What am I doing wrong? Any help would be greatly appreciated.

Document Management using Zope
by Siu, Paul 23 Aug '03

23 Aug '03

Hi, I need to create a system that is mostly for web content management (HTML, XML, etc), but also have support for traditional "fat" documents like Microsoft Office. Basically I want to be able to version fat documents and route them through workflows. I was trying to figure out if this is feasible in Zope. >From what I can tell from reading the docs, Zope uses an object orient database Zodb. Zodb seemed to be able to handle content, but can it handle "fat" content reliably? I guess one issue would be caching, since caching a large object in memory would chew up memory quickly. Another problem is that Zope lacks a reliable version control. Zope can version by saving old transactions, but the transactions are lost after a pack. What I need is someway to specify specific verions like in a CVS. I also need to keep the old version around until corporate record retention policy indicate that it should be deleted. I have heard that Zope3 has this feature, but Zope3 is too far away. Plone seems to have a mechanism through CMFStaging, but how reliable is that? Can I migrate the document from the 2.x solution to the 3.0? Better yet, is there a DM type product out there? Paul

Threading gotchas?
by Andrew Veitch 23 Aug '03

23 Aug '03

I'm just about to do some threading in a Zope application. At the moment it relies on an external cron job or Xron to call a method reasonably regularly but I would like to use a Python thread instead. I'm not particularly bothered if the thread is called slightly late. I'm just wondering if there are any particular gotchas? Or will it work just as it does in ordinary Python? Andrew

anonymous user: Zope 2.6.1/Plone 1.1/Mac OSXS 10.2.6
by baiewola＠netscape.net 23 Aug '03

23 Aug '03

Hi everyone. My zope site was 100% password-restricted (anonymous user assigned no privileges), but now I need to make one folder at the root level accessible by anonymous login. In the security tab of that folder, I unchecked the acquire permissions boxes of everything and checked only the "view" items. But I can't log in with a blank username/password. I get this message from verbose security: Error Type: Unauthorized Error Value: (item 0): Your user account does not have the required permission. Access to 0 of [(Application instance at 18a3760), (Folder instance at 18cfcd0)] denied. Your user account, Anonymous User, exists at /acl_users. Access requires one of the following roles: ['Manager', 'View']. Your roles in this context are ['Anonymous']. I don't understand this error, since I'm logging in without a name or password. Shouldn't it automatically assume I'm an Anonymous User with the Anonymous role? __________________________________________________________________ McAfee VirusScan Online from the Netscape Network.

About LDAPUserFolder, memberships and LocalRoles...
by Gelin Patrick 23 Aug '03

23 Aug '03

Hi, I use LDAPUserFolder and when I want to assign LocalRoles I get into trouble because users are not display if they never login a first time. I think that when a user make a login it is registered as membership and he can be listed by LocalRoles. So the question is how can I register my LDAP users as membership automaticaly ? Thanks.

zldap connections
by Andrew Altepeter 23 Aug '03

23 Aug '03

I'm working on an alumni directory for the college, which uses openldap as the directory service. We are using acl's to restrict which attributes user have access to based on their context (staff, student, alumni, guest, etc). This means that the alumni directory needs to bind to ldap as each user. We want to use zldap, but the Ldap Connection object creates a connection, bound as one user. Is it possible to have 'dynamic' ldap connections (and use the rest of the zldap package), ones where you can re-bind as another user? Or is there some other (better) way to do this? I've seen other products out there which allow this by using an ldap user folder, however we have a custom user folder that integrates with our institutions single sign-on server, so that won't work (and we have a different method of retrieving a users password). Any help would be great! Thanks! Andy Altepeter Web Developer Bethel College & Seminary

How user edit his account?
by Praveen Kumar 23 Aug '03

23 Aug '03

Dear List, I would like to know one thing. I'm using exuserfolder to provide the user accounts. While logged into the Zope application we can modify the existing user account information. I would like to know how user can modify his own account through web? If we hosted the site then User can logged into the site by giving his username and password. Once he logged in then he should able to modify his account. Please give me some ideas. -- Regards Praveen Kumar, SoftPro Systems Ltd, Ph: 91-40-23111806 Mobile: 98494 46416

zope hangs
by Declan Shanaghy 23 Aug '03

23 Aug '03

Since i upgraded to redhat 9.0 ive noticed that zope hangs a lot. It will accept a connection but never sends a response. Restarting zope fixes the problem for an undetermined time. Sometimes it'll stay sane for a long time, other times 1 or 2 requests later it hangs. I dont know if its redhat 9 related, but only since upgrading has this happened. Has anyone else seen this?
