cc471b1103 From Magnus Kessler, "Attached are a number of files where I have tried to fix up some of the
documentation. I have accumulated them over some time, but rebased onto the
subversion trunk."

2b2ea4487a From Tim Moore, new more robust observer_ptr<> implementation 2010-05-14 12:14:14 +00:00

b09757bdb8 Refactored the osg::Referenced observerset code so that it now uses a dedicated ObserverSet class,
which utilises a global recursive mutex that is dedicated to manage Observer and ObserverSet.

The new global mutex for observers avoids problems with deadlocks that were occurring previously when
an osg::Refenced object was being deleted at the same time as on osg::ObserverNodePath.

644b2e15d1 Refactored the osg::Observer to introduce a new bool Observer::objectUnreferenced(void*) method that adds
the extra capability of making it possible for Observers to assume ownership of a object that would otherwsie be deleted.

Added a thread safe ref_ptr<T> observer_ptr<T>::lock() method for robust access to an observed object.  This
makes observer_ptr<> more equivilant to boosts weak_ptr.

69f9377093 Fixed effective leak in Program::PerContextProgram caused by previously osg::State keeping a set of std::ref_ptr<Program::PerContextProgram> without ever pruning this list.
The fix was to convert the osg::State to use C pointers for the set of applied PerContexProgram objects, and use the osg::Oberver mechanism to avoid dangling pointers for being maintained in osg::State.

ac975bf79a Added a Refrenced::getGlobalReferencedMutex, and OpenThreads::ScopedPointerLock() and use of this in add/removeParent() codes
to avoid threading problems when using atomic ref counting.

eb5a656f4e From Neil Groves, added intrusive_ptr_add_ref and intrusive_ptr_release methods to enable
usage of boost::intrusive_ptr<> with osg::Referenced objects.

5a4ce5a387 From Mathias Froechlich, "Attached is a change to that atomic stuff to move the win32, msvc
implementation of the atomic increment and decrement into a implementation
file.
This way inlining and compiler optimization can no longer happen for these
implementations, but it fixes compilation on win32 msvc targets. I expect
that this is still faster than with with mutexes.

Also the i386 gcc target gets atomic operations with this patch. By using an
implementation file we can guarantee that we have the right compiler flags
available."

eac3dc1963 From Paul Melis, "Here is a list of fixes to misspelled APIs. Unfortunately, more than one
of these are public APIs and therefore will break linkage to existing
shared libraries."

Note from Robert Osfield, updated wrappers.

6d9641a78b Added a concrete osg::DeleteHandler implementation which provides support for
retain objects for several frames before deleting them.  Also added RenderStageCache
into CullVistor.cpp that is used for handling RTT osg::Camera's that are being
used in double buffered SceneView usage.

73fffe1800 Made Refernced::setThreadSafeReferenceCounting(bool) a virtual then overrode
this in various scene graph classes to ensure that the scene graph gets
updated as well as the objects that the initialial call is made from.

a8c52a90f0 Added selective support for thread safe ref/unref such that the rendering
backend now doesn't use thread safe ref counting where multi-buffering exists.
This reduces the overhead of multi-threading.

8f2ffb7c2d Added new observer_ptr templated smart pointer to allow one to retain pointers
to objects but have the pointer reset to null if that object is deleted.

e01990d419 Made the osg::Referenced Mutex be declared as a pointer to a Mutex, with the
Mutex allocated dynamically when required. Added the following methods to
help manage the usage of the mutex:

        void setThreadSafeRefUnref(bool threadSafe);

        bool getThreadSafeRefUnref() const;

de0e616433 Added new methods into osg::Referenced for controlling the use of thread safe
ref/unref:

        /** Set whether reference counting should be use a mutex to create thread reference counting.*/
        static void setThreadSafeReferenceCounting(bool enableThreadSafeReferenceCounting);

        /** Get whether reference counting is active.*/
        static bool getThreadSafeReferenceCounting();

c406d2476f Removed the osg::Referenced::createCount() and deleteCount() methods and
associated variables which were only compiled in on debug build.  These optional
methods/static vars were causingproblems when mixing debug and release builds.

884b2730e8 Added a DeleteHandler into osg::Referenced so that it can delete objects

the users needs to address this issue.

12226e4371 Converted the instances of const built in types being returned from methods
and passed as paramters into straight forward non const built in types,
i.e. const bool foogbar(const int) becomes bool foobar(int).
