[Zope3-checkins] CVS: Zope3/src/zope/app/browser/services - hubcontrol.pt:1.4

Thu Aug 7 12:33:18 EDT 2003

Update of /cvs-repository/Zope3/src/zope/app/browser/services
In directory cvs.zope.org:/tmp/cvs-serv6429/src/zope/app/browser/services

Modified Files:
	hubcontrol.pt 
Log Message:
Added lazy unregistration to the object hub. It's currently possible to leave invalid object registrations when containers are deleted. These changes help to mitigate this problem until a more robust solution is in place. Details of the lazy unregistration are documented in test_objecthub.py.

These changes minimize the impact to the hub. More aggressive checks/unregistration of missing objects can be added if need be.

This change also includes the addition of a temporary hub method - unregisterMissingObjects - for unregistering invalid/missing objects. This functionality is exposed in the hub control form through a button the user can click to remove any missing objects.
