Checker: FORWARD_NULL (help)
File: base/src/extern/libopenjpeg/jp2.c
Function: jp2_decode
Description: Variable "image" tracked as NULL was dereferenced.
fixed by just updating to latest version of the file from
external svn branch.

+ fixed Python method, PyArg_ParseTuple already checks for errors, no returning of NULL, thanks Campbell too)
+ added linear/angular spring for each of the 6DOFs of a generic 6dof constraint. This makes the generic 6dof constraint very versatile.

(todo: expose this setting in World setting GUI)
Expose contact processing threshold in Advanced GUI, next to rigid body margin, called CPT.
Default to 1, makes rigid body stacking a bit more stable, smaller values makes sliding easier (at the cost of easier jittering).
Disabled for 'dynamic' objects that don't rotate, because characters etc. always need smooth sliding.
Should make generic 6DOF constraint more useable, and rigid body stacking more stable (warmstarting was accidently switched off)
If time allows, a few more minor last-minute 2.49 fixes might follow.

This commit contains a number of performance improvements for the
BGE in the Scenegraph (parent relation between objects in the
scene) and view frustrum culling.
The scenegraph improvement consists in avoiding position update
if the object has not moved since last update and the removal
of redundant updates and synchronization with the physics engine.
The view frustrum culling improvement consists in using the DBVT
broadphase facility of Bullet to build a tree of graphical objects
in the scene. The elements of the tree are Aabb boxes (Aligned
Axis Bounding Boxes) enclosing the objects. This provides good
precision in closed and opened scenes. This new culling system
is enabled by default but just in case, it can be disabled with
a button in the World settings. There is no do_version in this
commit but it will be added before the 2.49 release. For now you
must manually enable the DBVT culling option in World settings
when you open an old file.
The above improvements speed up scenegraph and culling up to 5x.
However, this performance improvement is only visible when
you have hundreds or thousands of objects.
The main interest of the DBVT tree is to allow easy occlusion
culling and automatic LOD system. This will be the object of further
improvements.
I also did some small tweaks. removed ifdef's for pluginapi
didn't need them there.
Fixed it so the filesel shows jp2 as image files.
(I'm going to do makefiles next)

In particular, the Bullet vehicle seems broken, and some soft-body demos don't work.
No new features or benefits are added yet, but a few improvements are planned before Blender 2.49 release.
Please update the build systems, and add those 3 files:
extern/bullet2/src/BulletCollision/CollisionDispatch/btActivatingCollisionAlgorithm.cpp
extern/bullet2/src/BulletCollision/CollisionDispatch/btGhostObject.cpp
extern/bullet2/src/BulletCollision/CollisionShapes/btConvexPointCloudShape.cpp
I'll watch the Blender mailing list, in case this commit causes some issues.
* giving compileflags, cc_compileflags and cxx_compileflags to BlenderLib() now actually overrides any other setting (so there's no unclarity when ie. conflicting options are being specified in REL_CFLAGS et al). These are set after either release or debug flags, but before any *_WARN flags (so those stay maintained).
* add cxx_compileflags for GE parts on win32-vc to have better performance.
* NOTE: if platform maintainers (OSX and Linux) could check and do the same for their systems. Not vital, but probably very, very much welcomed by GE users.
to compile blender with gcc on IRIX, IRIX_USE_GCC needs to be set to true in
user-def.mk.
Other changes related to irix:
* compile solid from extern/
* don't build plugins (yet) with "make release" when using gcc (the shell
script used assumes MIPSpro is installed)
* use statvfs instead of statfs on irix, like done on solaris
* use external libs from $(LCGDIR) instead of /usr/freeware
* use glew header files from $(LCGDIR)/glew instead of the ones installed on
the system (this applies to other platforms as well)
* ffmpeg support currently is disabled on irix
* add support for building redcode on win32/msvc, but disabled for now, as there are linking problems
- I cleaned the redcode sconscript - the copying of headers within the source tree is not a clean solution
This needs to be fixed later on. For now, lets use redcode from extern/ until a better way is found.
- Code has been changed to reflect this (ie. deprecated functions are not anymore used)
* clean up the C and C++ compiler flags mess.
- in the environment construction of BlenderLib all the compile flag governing options have been split in the *C*, *CC* and *CXX* containing equivalents.
C is for C compiler only flags. CC is for C and C++ compiler flags and CXX is for C++ compiler only flags.
All the platform default config files need to be double checked and fixed wherever it looks necessary. Either DIY, or send me a note with needed changes.
- a start for the BlenderLib parameter list has been made - all the SConscripts need to be checked and modified to hand in flags properly.
* A theeth request: make -jN settable in the config file.
- I give you BF_NUMJOBS, which is set to 1 by default. In your user-config.py, set BF_NUMJOBS=4 to have 4 parallel jobs handled. Yay.
Enable soft body collision clusters by default.
Add option to 'disable collision' button between soft body and rigid body connected by constraint (option was already available between two rigid bodies)
#if defined (__sun) || defined (__sun__) || defined (__sparc) || (defined (__APPLE__) && ! defined (__i386__))
Also includes a fix to uninitialized variable (can cause failing collisions).
If possible, report all changes to extern/bullet2 to http://code.google.com/p/bullet/issues/list
I changed sqrtf to sqrt in elbeem
in bullet2 I added defines found in floatpatch.h eventually
we should make a "floatpatch.h" that all of blender can use.
Kent
and noticed dos line endings in a bunch of files so ran
dos2unix on everything in bullet2.
Erwin, I noticed there are a few files that do not have
license info in them, couple of quick examples are: btDefaultMotionState.h
btHashMap.h btQuickprof.cpp
could you take a look at add where needed? If you want I can give a list
of files I think should get it added and or just add the standard one
say the one in src/btBulletCollisionCommon.h
