This means script authors can perform actions using these callbacks rather then on drawing which puts blender in a readonly state.
Simple example:
import bpy
def up_func(self, context):
print("test")
bpy.types.Scene.testprop = bpy.props.FloatProperty(update=up_func)
bpy.context.scene.testprop = 11
# prints -> test
- rename rna collection structs Main prefix to BlendData: eg, MainObjects --> BlendDataObjects
- printing python collection now prints its type (when available)
- renamed shadowed vars in bpy_rna.c.
- when making functions static I also made debugging/test functions static, reverse and add definitions to headers instead.
- rather then use unlink="None", just don't pass unlink as a keyword. This is more pythonic.
- added an RNA flag for properties which cant be unlinked by setting to None.
- Python calling operators didn't run WM_operator_properties_sanitize() so enum functions called from python were given a NULL context.
- PROP_ENUM_NO_CONTEXT and PROP_NEVER_NULL used the same value in the enum (possible conflict).
An example of how this is useful - an importer mixin could define the filepath properties and a generic invoke function which can run the subclasses exec for each selected file.
- Panels and Menus now skip the property check when registering.
- renamed _idproperties_ to _idprops_ in function names, function names were getting very long.
* Changed UI code to display image browser for PROP_IMAGEPATH
* Set the icon_filepath RNA property for brushes to use PROP_IMAGEPATH
* Changed preview icon drawing to ignore unset icons
* Fixed const warnings in brush RNA
- pose markers new/remove
- font load/remove
- world load/remove
- particles new/remove
commented out node-tree for now since from what I can tell these have to be atteched to material/scene/texture (unlike other ID types)
* Division by zero fix for TNT SVD code.
* Sound fix, in case ffmpeg decode fails, don't use the samples.
* Fix for incorrect bounds of transformed objects in new raytracing code.
* Gave memory arena's a name used for allocations for easier memory
usage debugging.
* Dupligroup no_draw option was using layers but not restrict view/render
setting. (not a bugfix exactly but would do display list context switching
while drawing for no reason).
* Fix objects instanced on hair particles not giving consistent results
when the object is transformed.
* New math functions: madd_v4_v4fl, len_squared_v3v3, interp_v4_v4v4v4,
mul_v4_m4v4, SH and form factor functions, box_minmax_bounds_m4.
* mul_m4_m4m4 and mul_m3_m3m3 now accept the same pointers for multiple
arguments.
* endjob callback for WM jobs system.
* Geometry node uv/color layer now has search list/autocomplete.
* Various small buildsystem tweaks, not strictly needed yet in trunk.
This is set on keymap item operator properties and macro definition operator properties to make them non-contextual (since the context at definition time is most likely not the same then at execution time, it's better to have all options visible).
This removes some more errors in keymap export and import.
This commit also sanitize some enum item function, making sure they can cope with null context and have usable defaults in that case.
Fixed and completed support for returning multiple values. This includes support for returning arrays, both fixed and dynamically sized. The way this is achieved is by storing an additional int value next to the dynamic parameter in the ParameterList stack which gets passed to the C function as an additional parameter. In the case of return parameters it is duty of the C function to set this int to the correct length value for the dynamic parameter (which makes sense). Note that for the dynamic output/return parameter it is assumed the function has allocated that memory (which gets freed automatically).
Also, I cleaned the makesrna's bridge function generation code a bit and renamed PROP_RETURN to PROP_OUTPUT, which represents better the reality now that there are multiple returns. The function now to mark multiple returns (outputs) is RNA_def_function_output.
For an example, look at Action.get_frame_range in rna_action_api.c, by the way Aligorith I removed the #ifdef for this function now that there's support for returning arrays, feel free to modify (the function seems to work).
blender supports type changing for textures in a way that python doesnt.
add a new general function.
Example usage:
tex = bpy.data.textures.new("Foo")
tex.type = 'IMAGE'
tex = tex.recast_type()
Macro to give the number of users accounting for fake user.
ID_REAL_USERS(id)
Use this so you can remove a datablock if it has a fake users as well as apply transformations to it in the 3D view.
Move api function bpy.data.add_texture() --> bpy.data.textures.new()/remove()

- ToolSettings had its id.data set to NULL when taken directly from the context (causing a crash in cases)
- menu for changing vert/edge/face selection now a python menu, removed operator.
- wm.context_set_value(), would really prefer not to have this since it evaluates the value as a python expression however there are no ways to define arrays in PyOperators
* Property update functions no longer get context, instead they get only
Main and Scene. The RNA api was intended to be as context-less as
possible, since it doesn't really matter who is changing the property,
everything that uses the property should be updated.
* There's still one exception case that use it now, screen operations
still depend on context too much. It also revealed a few places using
context where they shouldn't.
* Ideally Scene shouldn't be passed, but much of Blender still depends on
it, should be dropped when we try to support multiple scene editing.
Change was planned for a while, but need this now to be able to call
update without a context pointer.
After testing and feedback, I've decided to slightly modify the way color
management works internally. While the previous method worked well for
rendering, was a smaller transition and had some advantages over this
new method, it was a bit more ambiguous, and was making things difficult
for other areas such as compositing.
This implementation now considers all color data (with only a couple of
exceptions such as brush colors) to be stored in linear RGB color space,
rather than sRGB as previously. This brings it in line with Nuke, which also
operates this way, quite successfully. Color swatches, pickers, color ramp
display are now gamma corrected to display gamma so you can see what
you're doing, but the numbers themselves are considered linear. This
makes understanding blending modes more clear (a 0.5 value on overlay
will not change the result now) as well as making color swatches act more
predictably in the compositor, however bringing over color values from
applications like photoshop or gimp, that operate in a gamma space,
will give identical results.
This commit will convert over existing files saved by earlier 2.5 versions to
work generally the same, though there may be some slight differences with
things like textures. Now that we're set on changing other areas of shading,
this won't be too disruptive overall.
I've made a diagram explaining the pipeline here:
http://mke3.net/blender/devel/2.5/25_linear_workflow_pipeline.png
and some docs here:
http://www.blender.org/development/release-logs/blender-250/color-management/
Also:
* UI now takes ID self check flag into account so that e.g. it
doesn't offer to the make object it's own parent.
* Mesh loop cuts number of cuts had wrong limits.
* Don't use mesh_get_derived_final in modifier stack, but
ob->derivedFinal instead. Avoids crashes on dependency loops,
and in case there is no loop it should have been created.
Keymaps are now saveable and configurable from the user preferences, note
that editing one item in a keymap means the whole keymap is now defined by
the user and will not be updated by Blender, an option for syncing might be
added later. The outliner interface is still there, but I will probably
remove it.
There's actually 3 levels now:
* Default builtin key configuration.
* Key configuration loaded from .py file, for configs like Blender 2.4x
or other 3D applications.
* Keymaps edited by the user and saved in .B.blend. These can be saved
to .py files as well to make creating distributable configurations
easier.
Also, user preferences sections were reorganized a bit, now there is:
Interface, Editing, Input, Files and System.
Implementation notes:
* wmKeyConfig was added which represents a key configuration containing
keymaps.
* wmKeymapItem was renamed to wmKeyMapItem for consistency with wmKeyMap.
* Modal maps are not wrapped yet.
* User preferences DNA file reading did not support newdataadr() yet,
added this now for reading keymaps.
* Key configuration related settings are now RNA wrapped.
* is_property_set and is_property_hidden python methods were added.
one active. Now there's a function to get the pointer + property from
the UI, just like for the animation operators.
Also two fixes for fileselect events, regions are now preserved so that
context is restored to the old region, and the cancel callback is called
when the operator is cancelled.
