--------------------------------------------
Summary: We don't have to update the RDN index up to the top when
moving an entry
Key: DIRSERVER-2153
URL: https://issues.apache.org/jira/browse/DIRSERVER-2153
Project: Directory ApacheDS
Issue Type: Improvement
Affects Versions: 2.0.0-M21
Reporter: Emmanuel Lecharny
Fix For: 2.0.0-M22
When we move an entry, we update all the ascendants up to the root, in order to
update the number of descendants.
We can save us a few updates by stopping when we met the common ascendant,
because it will have the same descendant number.
For instance, moving an entry from A/B/C/D/xxx to A/B/E/F/xxx will decrement
the {{nbSubordinate}} counter for C and D, increment it for E and F, but for B,
it will remain the same.
Doing so, in this very example, we would save 4 updates, dividing by 2 the
number of updates.
