CodeSnip Old Code (SVN)

Replaced private object destruction controller of TDBDataPool<T> with an instance of TObjectDestructionManager to permit or deny freeing of data items in the pool.

* Added optional Lock parameter to TObjectDestructionMgr.HookController method and added test to test case unit to check case when Lock is True.
* Changed anonymous function in TObjectDestructionMgr.Create to raise EBug if unknown permission kind detected.

* Added new Lock method, Locked property and new write accessor for FreeController property of TControlledConditionalFreeObject. Attempting to write a non-nil FreeController property when locked now raises new ELocked exception.
* Added ELocked exception to UBaseObjects unit.
* Added new unit test for Lock method and Locked property of TControlledConditionalFreeObject.

* Modified existing tests to compile and pass now that Controller property removed from TObjectDestructionMgr.
* Added new tests for new TObjectDestructionMgr.HookController method and for TObjectDestructionMgr constructor.

Replaced TObjectDestructionMgr.Controller property with HookController method.

There was a duplicate name problem with the new "Database" namespace so this was altered to "DB". All units in the namespace were renamed accordingly. All related test units were again renamed in line with their related "DB" units. Unit references etc were also adjusted.

* Renamed NsDatabase.UDataPool.pas as Database.UDataPool.pas.
* Renamed TestNsDatabaseUDataPool.pas as TestDatabaseUDataPool.pas and modified it to refer to renamed Database.UDataPool unit.

* Renamed NsDatabase.UDataItem.pas as Database.UDataItem.pas.
* Modified all units that reference NsDatabase.UDataItem.pas to reference renamed unit.
* Renamed TestNsDatabaseUDataItem.pas as TestDatabaseUDataItem.pas.

* Renamed NsDatabase.UDatabase.pas as Database.UDatabase.pas.
* Renamed TestNsDatabaseUCookies.pas as TestDatabaseUCookies.pas and modified it to refer to renamed Database.UDatabase unit.

* Renamed NsDatabase.UCookies.pas as Database.UCookies.pas.
* Modified all units that reference NsDatabase.UCookies.pas to reference renamed unit.
