70dfd11531 From Tim Moore, 
Fixes to race in DatabasePager where a parent PagedLOD
of newly loaded subgraph has been expired.

Clean up of visitor naming to make it clearer what role it has.

e0924886bd Added support for enabling the assignment of PixelBufferObjects to loaded Images to aid the download of images to the GPU. 
Feature can be enabled/disabled (default) by setting the env :

   OSG_ASSIGN_PBO_TO_IMAGES  to ON or OFF

11cd5a89ed Implemented better coupling of DatabasePager and IcrementalCompileOperation, 
removing functional duplication and opening the door to dynamic enabling/disabling
of pre compile based on load.

f61a6aa4e7 Refactored the way that the DatabasePager passes the Terrain decorator node onto the TerrainTile. 
The DatabasePager now passes the Terrain pointer into the ReaderWriter's via osgDB::Options object,
rather than pushing a NodePath containing the Terrain onto NodeVisitor.  This
change means that the DatabasePager nolonger needs to observer the whole NodePath and
will be lighter and quicker for it.

The change also means that ReadFileCallback can now run custom NodeVisitor's on the scene graph without
having to worry about TerrainTile's constructing scene graphs prior to the Terrain being assigned.

Also changed is the NodeVisitor::DatabaseRequestHandler which now requires a NodePath to the node that you wish
to add to rather than just the pointer to the node you wish to add to.  This is more robust when handling scenes
with multiple parental paths, whereas previously errors could have occurred due to the default of picking the first
available parental path.  This change means that subclasses of DatabasePager will need to be updated to use this new
function entry point.

b5d4d9954a From Tim Moore, Dereference the databaseRequest while the queue is locked. This prevents the request from being 
deleted at an unpredictable time within addLoadedDataToSceneGraph.

8f2497e21d From Wojciech Lewandowski,"These are our changes to DatabasePager. To check if parent PLOD is registered, I resurrected PagedLODList::containsPagedLOD() method. This method was available some time ago, but got removed and was not currently present in trunk. To add this method I had to also modify the DatabasePager header. " 2010-10-01 15:37:35 +00:00

2ea6aa050e Refactored the PagedLODList implementation so that it's now done via a base class that enables different implementations to be easily tried. Initial concrete PagedLODList is the SetBasedPagedLODList. 2010-06-03 14:14:40 +00:00

054d5606fb From Tim Moore, "This is a patch that allows a ref_ptr to be constructed using an observer_ptr argument, which is locked. This is shorthand for declaring the ref_ptr and then passing it to observer_ptr::lock().

d26a8474e7 Changed the ref_ptr<T> observer_ptr<>::lock() method to be 
bool observer_ptr<>::lock(ref_ptr<T>&) to avoid the temporary ref_ptr<>'s
being created and destroyed on the stack along with the associated ref/unref() operations

31ec835002 From Jason Beverage, "Here is a small fix to the DatabasePager to fix a crash if you were 
running with the OSG_NOTIFY_LEVEL set to INFO.

An iterator was being erased, and then referenced to display a
message.  Just changed it to display the message first, then erase."

Robert Osfield
1319e270f6 Refactored the way that the RequestQueue's are pruned and highest prioty items taken from them so the operation is 
now O(n) rather than O(nlogn) where n is the number of requests.  The refactoring also cleans up the access of the
request lists so that the code is more readable/maintainable.

9f8a4be2cd Refactored DatabasePager so that it nolonger takes ref_ptr<PagedLOD>, but instead uses a custom version of observer_ptr<>. 
This change should make it possible to delete PagedLOD's independantly from the DatabasePager, and also prevent issues of
consistency of the pager when subgraphs when are cached elsewhere in the application such as in the Registry filecache.

f8fc4f66a8 Added RequestQueue destructor and DatabaseRequest::invalidate() and valid() methods to allow the 
destruction of RequestQueue to remove any pointers held in DatabaseRequest attached to the scene graph, and to
prevent their subsequent use in cases where the scene graph is attached to a new DatabasePager.
