Texture nodes hang when nodes have a cyclic case.
Added a (temp?) provision to tag node->need_exec zero for cyclic
nodes, and added check for this in texture nodes.
There was also a bug in 'tag changed' for texture nodes, which not
only tagged, but also called the tree exec (should not happen!).
In general the texture exec needs recode; it doesn't use the stacks
as provided per node, but recurses itself to previous nodes, giving
problems like this. Node execs should only do their own bizz, the
node system handles dependency and eval order nicely already.
* Added back backgrounds behind buttons for modifiers and driver targets
* 'Protect' toggle doesn't draw for F-Curves with no keyframes to prevent editing on anymore
* Inserting keyframes on objects using builtin keyingsets now use the right names
* For new buttons spaces, automatically set horizontal/vertical
align depending on size, instead of free.
* Cleaned up the UI panel API. There's now a new uiBeginPanel
function which takes a panel type, and a uiEndPanel which takes
the final size. uiNewPanel* functions will be phased out.
* Animate the re-alignment when a panel size changes, e.g. when
enabling dupliframes.
* Load ui scripts from the release/ folder first if it is
available. This makes it easier to edit ui scripts, since it
will directly use the original files which avoids having to
run the build system.
* Improve editing of panel types while blender is open. That
means fixing some issues with lacking updates, overlaps, strange
ordering. It even does an animation now when the panel resizes.
* Added extra parameter to generic unique name finding function BLI_uniquename() for specifying the delimeter between non-unique parts of the name and digits.
* Driver target variables now get unique names by default.
* The UI for adding and modifying drivers is now functional, and reflects the new way they work. It has also been tidied up a bit (from the previous incarnation), with RNA buttons starting to be used (currently limited to the 'Path' settings).
* Fixed errors in RNA wrapping for drivers
* Don't call generic layout hints templates anymore, i.e.
TemplateRow becomes Row, etc.
* Added more general layout nesting, using uiLayoutSplit()
and uiLayoutBox() functions, for which the sublayouts
can then be accessed using uiLayoutSub(), to put items
in those sublayouts.
* Some steps to make the layout decisions, like which items
to put in which columns, independent of the width of the
window or the text in the buttons. We want the layout to
be stable under resizes and translations.
* Added an "expand" parameter to uiItemR, used now to expand
enums into a row instead of using a menu.
Drivers now support multiple targets which act as 'variables'. The targets have a short 'name' (see later), and reference some property (in much the same way as F-Curves do, using RNA-Paths) which acts as the 'value'.
These named variables can then be used in a Python Expression which relates them to each other for more fine-grained control over the result of the driver. By using only the names of these variables in the expressions, we are able to define expressions/relationships in a much more readable way, as data access is separated from data use. This makes the underlying relationships easier to understand.
By default, if no Python Expression is given, the variables are simply averaged together, so old files won't break. :)
For example, check the following diagram (thanks Cessen/Nathan V from Peach team):

TODO List:
* Depsgraph building for new driver relationships doesn't work yet. This needs to be recoded again, but this new system makes this much easier, since the targets are clearly defined (i.e. no need to parse py expressions to get list of objects)
* Graph Editor interface for editing these needs to be rewritten
* Python function for evaluating these expressions is needed (Campbell?)
* Replaced a quicky hack needed to get PoseLib working with a proper new group-naming option for KeyingSets. Now, all builtin KeyingSets will use the name of the data (i.e. Object or PoseChannel) as the name of the group new channels are added to
* Fixed a bug with LocRotScale builtin KeyingSet, which meant that scale keyframes were not getting added.
* TAB key (toggle original pose) now works again. Previously, events were flying past too quickly.
+bvhtree cache (if the derived model doenst gets destroyed then the same BVHtree can be used)
this was needed to allow shrinkwrap constraint to be usable.
It has been ready for a long time.. but only got merged now, for 2.49.
Free python modules defined within the blendfile between loading scenes since they would end up accessing old GameLogic, Rasterizer modules as well as old game engine data in the module namespace which can cause problems.
- Fun for testers: Added "Redo Operator" Panel in view3d 'nkey' region.
It's going to be part of tools UI I know, but this will give good
tests of what goes on with operators. I had to add small fixes in
Transform for it already. :)
One important issue to note is that it lists every operator, also from
non-3D-window ops. Needs checked or classified somehow.
- Fix: removed bad 2.4x hack from how pulldown menus were defined. Made
widget code cleaner, and will show menus like SHIFT+A correct now.
Imagepaint make sure ibuf exists before we use it. This is CID# 545
editmesh_tools.c make sure were not indexing array with -1 This is CID# 137
(also removed some trailing whitespace I found)
anim5.c totlen could be -1 so check its > -1 This is CID# 134

* For RNA wrapped functions, the prototypes of the original
function being wrapped is now generated as well. This is
an extra check to ensure that the function is correctly
wrapped. It's printed after the function is used to still
get proper warnings in case the #include for it is missing.
- fix for multiple viewpors broke single viewport (both work now)
- python could get uninitialized values from m_prevTargetPoint and m_prevSourcePoint
- getting the RayDirection for python could crash blender trying to normalize a zero length vector.
- added python attributes
- removed unused canvas from the MouseFocusSensor class
Following on from the methods added specially for PoseLib to only execute the F-Curves in a given Action Group, I've attempted to use this for evaluating Action Constraints on Pose Channels. This does rely on the F-Curves being in groups named according to name of the Pose Channel of interest, hence, we may need some way to be able to fine tune this later.
Preliminary tests seem to be promising, with rigs with quite a few action constraints being slightly more responsive (subjective test though). Please test thoroughly.
* Bug with confirming was due to mixed up order for events handling and updates for drawing. Now events are handled before relevant updates are done for drawing, since these only get called when an event occurs.
* View manipulations work again, and in a much nicer way thanks to the OPERATOR_PASS_THROUGH flags :)
* Search seems to work much better now again too...
This (most important part) of PoseLib now mostly works again. It even works for PoseLibs saved with the old animation system.
However, there are a few annoying bugs that need to be addressed still:
* When 'confirming' poses, the pose changes to the next one before PoseLib exits. I'm not quite sure where this is coming from yet...
* There are still a few minor bugs in the search-string code that will get ironed out
* AutoKeyframing doesn't work yet for this
Common cases of this are when python references an object from the AddObject actuator that has ended, or a scene has been loaded and the old objects freed.
This means some scripts will raise errors now in certain cases but better give the error early rather then failing silently with strange hard to track down behavior & crashes.
Added "isValid" attribute for checking objects are in a scene.
At the moment it uses the SceneGraph Node to check of the objects valid but it might be better to do this in a more generic way so scenes, meshes etc also have this check.
There is a problem importing 3ds files where I cant find a way to check if the transforms are applied to the vertex locations or not.
Since 2.44 I made the importer assume they were not since you can manually remove transformations, but not reverse.
Nevertheless most 3ds files have the matrix applied, better not give a bad import by default.
Did some research and other 3ds importers (lib3ds for eg), have the same problem and just assume the transformations applied.
3dsMax imports both correctly so there must be a way to tell but I could not link it to the 3ds version or other mesh options.
Added an option to workaround this problem in rare cases where its needed.
- KX_GameObject.cpp & KX_Scene.cpp, clear the dict before removing the reference in case there is a circular reference.
- The armature weakref list was being incref'd twice then decrefed twice (incref and decref were used incorrectly), now only once. My 'fix' broke this.
- In bpy_pydriver_create_dict the 2 refs added from running PyDict_SetItemString twice were undone when clearing the dictionary (added comment)
- changed Py_XDECREF to Py_DECREF int BPY_pyconstraint_update and BPY_pyconstraint_target, Py_XDECREF checs for NULL value which would have crashed blender before it got to Py_XDECREF anyway.
- after every error is reported (PyErr_Print), remove sys.last_traceback and clear the error, I found this fixed certain crashes (usually when starting the game engine or exiting blender), so best do this all the time.
- header_text.c, CcdPhysicsEnvironment.cpp, KX_CameraActuator.cpp - remove some warnings.
Changes:
* These still use the old hotkeys - Add (Shift-L), Remove (Alt-L), Rename (Ctrl-Shift-L)
* Outliner now shows PoseLib entry. Todo still is to use a different icon for this?
Notes:
* The code is now much simpler in many places :)
* Add and Rename operators require a string as input to set a new name for the Pose concerned. For now, I've just added a prop for this, which will hopefully be able to be filled in at some point.
* Cleaned up Keyframing API to get eliminate some of the problems faced during the original implementation of PoseLib, thus reducing code redundancy.
* Added new Animato evaluation functions specifically for use by PoseLib.
* Replaced parts of PoseLib code which relied on old animation system to the equivalent code for Animato. Notice the much cleaner + saner + compact code!
Next step is to operatorfy the PoseLib tools (while maintaining possibility for an API to some things) :)
own error, EXPP_incr_ret from a macro was an implicit decloration in BGL.c
For some reason this only crashed on 64bit linux
To my defence the BGE makes so many warnings that they become usless, need to improve the situation here at some point.
Another bug in the 'radius per vertex' feature in curves.
If you set front/back face off for curves, and make it bevel or give
depth, the curves should draw as tubes. This feature didn't work in 2.48
either...
Still unsure about this implementation, campbell can check!
