[Zope-dev] Zope 2.7: OrderSupport for ObjectManager

[Yuppie]

Hi!


Implementing the OrderedObjectManager proposal, we fleshed it out and 
modified it a bit. I made an initial checkin on a branch which reflects 
our current thinking. So this is your chance to discuss the changes 
before we merge it into the trunk.

The code:
yuppie-ordersupport-branch (Creating the branch went wrong a bit. Please 
just checkout lib/python/AccessControl, lib/python/OFS and 
lib/python/Products/OFSP.)

The original proposal:
<http://dev.zope.org/Wikis/DevSite/Proposals/OrderedObjectManager>


Some key issues:

1.) OrderSupport is a mixin class for ObjectManager. (using the 
CopySupport / FindSupport / UndoSupport pattern)

2.) 'Folder (Ordered)' is a 'Folder' with OrderSupport. (using the 
'Script (Python)' pattern for the meta_type to avoid a name clash with 
the existing OrderedFolder product or names like OrderedFolderLite)

3.) For the ZMI, we use the same 'main.dtml' as the ObjectManager. This 
way we avoid redundant code and make it easier for products that need to 
change the 'main.dtml'.


If there are no objections, I'm going to land this soon.


Cheers,

Yuppie



PS: For API Help, we have to copy (!) the Interface to OFSP/help? Right?
