You should probably ask about that on the mailing lists. 2.6.x is somewhat fossilized now and ther are many features in the 2.7 series that make it well worthwhile upgrading... cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

Persistent objects are held in per-thread caches; module-level stuff is ~ *not* part of that cache.

"Build a product" isn't an option for us, for a whole bunch of | reasons.

PAM Authentication & RSA Authentication Manager
by David Ayres 02 Feb '05

02 Feb '05

Hey Everyone, Any information I have found related to utilizing PAM for authentication dates back in 1999, so I'm assuming some solution has been found and I'm just not seeing it or the issue was dropped. I'm interested in implementing PAM for authentication mainly because I ideally need authentication that draws from a variety of sources including RSA's Authentication Manager. Any suggestions would be greatly appreciated! Thanks in Advance, Dave

by Gautam Saha 02 Feb '05

Hi Zopers: I know it is OLD version, but my IT folks are planning to upgrade the Linux box to Fedora Core 3. I ran a zope 2.6.1 instance and was wondering if zope 2.6.1 will run in FC3. Anyone running zope 2.6.1 in FC3? Thanks a lot for any response. Gautam PS: I am planning a upgrade to zope 2.7.x in summer.

InvokeFactory Question
by David Pratt 01 Feb '05

01 Feb '05

Hi. I have written a small Script Python to create a Portal Folder in a specific Folder (root/information) using a form. This creates the Portal Folder I want but instead of creating it in the information folder, I find it in the root folder. Can someone point out what I am doing wrong. If I use getId() on info_dir it gives me 'information' as the id so it appears I am creating it with the right object. I have manager proxy on the Script Python as well. Regards, David # Get portal url object url_tool = getToolByName(context, 'portal_url') # Get the path from the object portal_path = url_tool.getPortalPath() # Information directory (Folder) object info_dir = context.restrictedTraverse('%s/information' % portal_path) # Cancel button action if form_cancel is not None: RESPONSE.redirect('index_html?start:int=%s&sort=%s&reverse:int=%s' %(start, sort, reverse)) return None # Save button action if form_save is not None: category_id = context.cleanId(category_id) # Create a Portal Folder object info_dir.invokeFactory('Folder', category_id) # Get a handle on the new object created folder_obj = getattr(info_dir, category_id) # Get and fill the fields folder_obj.setTitle(title) folder_obj.setDescription(description) RESPONSE.redirect('index_html?start:int=%s&sort=%s&reverse:int=%s' %(start, sort, reverse)) return None

memory size optimization
by lty 01 Feb '05

01 Feb '05

Hi all, I am wondering if, having say 15 zope sites, with an average zexp size of 70Mb (but two of 200+Mb), it is better to have multiple instances or not in order to reduce overall memory consumption. I know memory is cheap, but I really can't upgrade my server, I have 1.5Gb of ram and I had to tweak zope.conf to reduce cache-size and pool-size. My server is still using swap, I have now 3 zope instances (mainly because of products versions conflicts) and I don't know if using 2 or only one instance would be better memory wise. Thanks in advance, Lorenzo

Connection between css files and their location
by Hoang-Vu PHUNG 01 Feb '05

01 Feb '05

Hi, I found the file manage_page_style.css.dtml (among other style sheets) under <Zope installation dir>/lib/python/App/dtml which I suspect is the same when I type /manage_page_style.css in the browser. Is there somewhere in the documentation that says the connection / convention between the stylesheet and its location. When I go to the root and try to use the find facility to look for eg. manage_page_style.css, it couldn't find it. Thanks for your answer. Hoang-Vu Découvrez le nouveau Yahoo!

LocalFS-1-3-andreas and Zope 2.7.2
by Chris Withers 01 Feb '05

01 Feb '05

Hi, Has anyone else here noticed that with Zope 2.7.x and LocalFS-1-3-andreas, when FS-based objects are changes through LocalFS, changes are also stored to the ZODB (you'll see a transaction for any change made in the Undo tab of the root of your Zope instance) as well? The changes are made up as follows (from fsdump.py): data #00000 oid=000000000000727e class=OFS.Image.Pdata data #00001 oid=000000000000727f class=OFS.Image.Pdata data #00002 oid=000000000000727c class=OFS.Image.Pdata data #00003 oid=000000000000727d class=OFS.Image.Pdata data #00004 oid=000000000000727b class=OFS.Image.Pdata data #00005 oid=0000000000007282 class=OFS.Image.Pdata data #00006 oid=0000000000007283 class=Products.LocalFS.LocalFS.ObjectWrapper data #00007 oid=0000000000007280 class=OFS.Image.Pdata data #00008 oid=0000000000007281 class=OFS.Image.Pdata ...and packing removes them. Does anyone know what's causing this and what could be done to fix it? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
