Putting the synchronized block back into AbstractBTree.touch() as it causes problems with the nested subquery join. See https://sourceforge.net/apps/trac/bigdata/ticket/201

Revision: 3897
http://bigdata.svn.sourceforge.net/bigdata/?rev=3897&view=rev
Author: thompsonbry
Date: 2010-11-04 20:26:49 +0000 (Thu, 04 Nov 2010)
Log Message:
-----------
Tentatively commenting out a synchronized block in AbstractBTree#touch() which shows up as a hot spot when loading triples with the RWStore. The synchronized block was added because of an exception arising out of the RingBuffer, but I think that the problem was fixed in the ring buffer so let's see if this breaks anything in the test suite.

Log Message:
-----------
IndexMetadata - Raised the maximum branching factor to 4k.
AbstractLocalTripleStore - Modified log information to report the average record size for a B+Tree.
DataLoader - Added "-verbose" option to show the performance counters and details from the indices and the store.
ConcurrencyManager, Journal, RWStrategy, RWStore - fixed some issues related to performance counter reporting.

- * The hook that accesses the RWStore to provide read/write services as opposed

+ * A highly scalable persistent {@link IBufferStrategy} wrapping the
+ * {@link RWStore} which may be used as the backing store for a {@link Journal}.
+ * <p>
+ * The {@link RWStore} manages allocation slots. This can translate into an
+ * enormous space savings on the disk for large data sets (when compared to the
+ * WORM) since old revisions of B+Tree nodes and leaves may be recycled
+ * efficiently.
*
- * The intent behind this approach is to try to manage the protocol differences
- * between the IStore implementation, assumed as a backing service to the CTC
- * ObjectManager, and an IBufferStrategy service for a BigData Journal.
+ * <h2>History</h2>
*
- * The most fundamental difference is with the root data, with RootBlock
- * including both low-level store data - such as metabits info - and higher
- * level, journal maintained data.
+ * The {@link RWStrategy} supports access to historical commit states in
+ * combination with the history retention policy of the
+ * {@link ITransactionService}.
*
+ * <h2>Compatibility</h2>
+ *
+ * The {@link RWStore} uses a distinct binary layout on the disk based which is
+ * not directly compatible with the WORM binary storage layer. The WORM and the
+ * {@link RWStore} uses the same file header and root blocks. However, the
+ * {@link RWStore} defines some fields in the root blocks which are not used by
+ * the WORM store such as the metabits info. In addition, some of the root block
+ * fields defined by the WORM store are not used by the {@link RWStore}.

Revision: 3876
http://bigdata.svn.sourceforge.net/bigdata/?rev=3876&view=rev
Author: thompsonbry
Date: 2010-11-03 13:17:41 +0000 (Wed, 03 Nov 2010)
Log Message:
-----------
Disabling the memory leak tests. Since I have restored the hard reference to the Journal in the WriteCacheService this is causing CI to fail with an OutOfMemoryException. The journal memory leak should really be addressed in the trunk as it is not specific to the quads branch.
