Subject svn commit: r1326604 - /directory/apacheds/trunk/jdbm-partition/src/main/java/org/apache/directory/server/core/partition/impl/btree/jdbm/JdbmPartition.java
Date Mon, 16 Apr 2012 13:22:32 GMT
Author: elecharny

New Revision: 1326604

URL: http://svn.apache.org/viewvc?rev=1326604&view=rev
Log:
fixed two issues :
- the indexed AT are now listed usig their OIDs (otherwise, the created index are deleted
immediately after having been created). Fixes for DIRSERVER-1712
- the index creation is now faster, as we don't iterate over the indexes, browsing the full
MasterTable for each index to create. We now do the opposite : we browse the MasterTable only
once and update all the index in one shot. Fixes for DIRSERVER-1711
