Description John Arthorne CLA 2005-04-06 14:13:59 EDT 
The workspace tree holds a String for the name of each resource in the
workspace.  When there are multiple resources in the workspace with the same
name, the strings could be shared between the resources.
Comment 1 John Arthorne CLA 2005-04-06 14:42:02 EDT 
This has been released.  The main advantage is sharing the names of the CVS
metadata directory and associated files.  This is present for every folder in
each project shared with CVS.  In my large self-hosting workspace, this saves
over 3MB of heap space.
Comment 2 John Arthorne CLA 2005-04-06 15:22:07 EDT 
Note that the fix was not just sharing resource names.  We now periodically walk
the entire workspace tree and share duplicates of just above every string we
hold.  This includes session priorities, marker keys and attributes, and
resource names.
