Joel Dice	3e0ab35ba1	fix PersistentSet.remove side-effect bug ... The whole point of PersistentSet is to provide non-destructive write operations, which means the add and remove methods should have no effect on previous revisions. However, a bug in remove caused shared tree nodes to be modified, corrupting any revisions with which they were shared.	2012-10-13 09:39:14 -06:00

Joel Dice	f0129665c6	fix corruption of old revisioins in PersistentSet ... In PersistentSet.remove, we were modifying the child node in place instead of making a copy to update, which would corrupt older revisions. This commit ensures that we always create a copy if necessary.	2010-07-30 12:23:41 -06:00
