[Exist-commits] eXist-1.0/src/org/dbxml/core/filer BTree.java,1.26,1.27

[Wolfgang M. M. <wol...@us...>]

Update of /cvsroot/exist/eXist-1.0/src/org/dbxml/core/filer
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv29485/src/org/dbxml/core/filer

Modified Files:
	BTree.java 
Log Message:
* Resolved concurrency conflicts when accessing a collection: avoid dirty reads on the old document
while it is being replaced.

* The index settings specified in the configuration are now also applied to reindexed document
fragments during an XUpdate.

* Removed unnecessary data from org.exist.dom.DocumentImpl to reduce its in memory size.

* Deferred addition of new documents to collection: when adding a large number of documents,
keeping the actual document objects in memory slows down the indexing process. Class Collection
now just remembers the document name, not the object itself.
