ASF	#483822	Fri Dec 08 04:28:06 UTC 2006	djd	DERBY-2164 (partial) Remove AccessFactory (store) from LanguageConnectionFactory and instead code can find the AccessFactory from the Transaction object. The AccessFactory getAccessManager() method already existed but was not exposed at the highest level.

ASF	#497593	Thu Jan 18 22:03:08 UTC 2007	djd	DERBY-2164 (partial) Add Database and Datadictionary objects that support a 'storeless' engine. This allows use of the JDBC & SQL layers and thus can execute any SQL statement that does not touch a table, e.g. VALUES 1+1. The build.xml builds into a separate classes.storeless folder which separates the code and allows testing of the existing monitor functionality to use multiple module.properties files. Top-level build changes to include this code will be in a subsequent commit, to allow it to be backed out easily if problems arise. Testing will also follow.

Backed out revision 497615 (with r497644), as it broke the build.

Knut Anders Hatlen added a comment - 11/Jul/08 11:06 AM

When the storeless engine is loaded, it throws a NullPointerException because impl.services.reflect.UpdateLoader's constructor calls createCompatibilitySpace() on the lock factory, which is null. The rest of the code in UpdateLoader correctly handles the lack of a lock factory, so I just added a null check in the constructor to fix it. Fixed in revision 675918.
