svn commit: r1595771 - in /directory/mavibot/trunk/mavibot/src:
main/java/org/apache/directory/mavibot/btree/
test/java/org/apache/directory/mavibot/btree/
Author: elecharny
Date: Mon May 19 07:26:31 2014
New Revision: 1595771
URL: http://svn.apache.org/r1595771
Log:
o Use the newBtreHeaders Map only when processing an update, instead of using the current's one. This allow all the modifications to be waiting for the encapsulating transaction to be committed.
o Fixed the TxnLevel counter manipulation : we weren't correctly decrementing it when we got some exception
o Close the recordManager in tests
