detects...
- invalid vertex range for edges/faces
- duplicate indices in edge/face
- duplicate edges/faces in mesh
- missing edges data in faces
At the moment it doesn't correct errors, but eventually it will do this.

========================
cube = bpy.data.objects['Cube']
foo = cube.vertex_groups.new('foo')
foo.add([1,3,5,7], 1.0, 'ADD')
for i in range(len(cube.data.vertices)):
try:
weight = foo.weight(i)
print('vert: %i weight: %f' % (i, weight))
except:
pass
foo.remove([1,3])
cube.vertex_groups.remove(foo)
Also use const char in many other parts of blenders code.
Currently this gives warnings for setting operator id, label and description since these are an exception and allocated beforehand.
Added extend option to lasso.
also...
- selecting bones wasn't checking their layer of if they were hidden in a number of places.
- fixed memory leak.
small unrealed changes
- added PBONE_VISIBLE macro
- renamed functions used for paint selectoin from *_tface to paintface_*. sine they no longer have anything todo with tface's.
- removed scanfill include from BLI_blenlib.h, this is only used in very few places and quite specific.
Noticed lasso select is broken for metaballs and face mask mode but this has been the case for a while, will look into it next.
- removed deprecated bitmap arg from IMB_allocImBuf (plugins will need updating).
- mostly tagged UNUSED() since some of these functions look like they may need to have the arguments used later.
- Added EM_project_snap_verts so other functions can re-use this, similar to old retopo_do_all().
- Changed how the normal for selected geometry is calculated, was accumulating half selected edge's into normals which was OK with even surrounding geometry but could skew too easily if the surroundings were not so even. Now use the 2D screen space selected edge vector to calculate the normals in relation to the target mouse position.
- Option to rotate initial selection, gives better results in some cases. (Ctrl+Shift+Click to disable)
http://wiki.blender.org/index.php/File:ClickExtrudeFix.png
- mesh.add_geometry(v, e, f) --> mesh.vertices.add(tot), mesh.edges.add(tot), mesh.faces.add(tot)
- mesh.add_material(mat) --> mesh.materials.link(mat)
changed material.link so it always adds a material even if it exists in the list, this behavior is good for users but not scripts since it can mess up indicies (some formats may have the same material set twice).
scene.active_keying_set --> scene.keying_sets.active
...same for active_uv_texture. active_vertex_color, active_keyconfig,
- move mesh.add_uv_layer() and mesh.add_vertex_color() into their collections
also have them return the newly created layer and dont set the layer active.
uvtex = mesh.uv_layers.new(name)
vcol = mesh.vertex_colors.new(name)
- use mirror when the option is enabled in editmode.
- fliped group names are used when they exist.
- only the setting that is edited will be applied to the mirrored verts group.
- copy value is applied to all mirrored verts of the selection.
- normalize normalizes all vgroups and mirrors.
utility functions defvert_sync and defvert_sync_mapped, similar to defvert_copy but does not remove existing groups and optionally creates groups as needed.
defvert_sync_mapped uses a an int array for mapping the flipped values.
2. Add action parameter to Select_All_Toggle operators, rename to Select_All.
Options are Toggle (default), Select, Deselect, Invert (same as select swap). This makes it possible to map separate hotkeys for select all and deselect all.
NOTE for Aligorith: I didn't change animation operators for select_all which already had an Invert operator. These should be fixed eventually.
Available in object mode (Object -> Join as Shapes), only works for meshes at
the present. Will merge all selected objects as shape keys on the active object,
if the vertex count is the same.
This does not keep references to the external objects like in some applications,
rather it's a quick way to update the shapes on the active object (perhaps after
importing new versions from external applications).
- use OBJECT_OT_mode_set rather then OBJECT_OT_*_toggle, better for using report output for script input. OBJECT_OT_posemode_toggle and OBJECT_OT_editmode_toggle are called by OBJECT_OT_mode_set.
- weight blending (Vertex specials menu), currently blends from surrounding unselected verts (nice for blending edge loops), but will eventually support face mask mode.
eg.
for v in me.verts: print(v.index)
added calc_edges as an option eg.
mesh.update(calc_edges=True)
This is needed when adding faces to an existing mesh which create new edges.
changed extrude, rip and duplicate to disable proportional editing however this gives a different problem now.
Commented in transform.c
// XXX If modal, save settings back in scene
this changes disables the option whenever the macro used used.
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.
* Move mesh API functions to mesh_data.c, would like to keep
RNA layer fairly thin, any non-trivial functions shoud be
in their modules.
* Replace mesh.create_copy by generic id.copy.
* Fix#19250: Mesh.add_geometry() in editmode fails silently,
now gives an error.
* copied I/O scripts
* copied, modified rna_*_api.c and rna_*.c
I/O scripts not working yet due to slight BPY differences and RNA changes. Will fix them later.
Not merged changes:
* C unit testing integration, because it is clumsy
* scons cross-compiling, can be merged easily later
* Split object_edit.c into multiple files:
object_add.c, object_edit.c, object_hook.c, object_relations.c,
object_select.c, object_transform.c.
* Rename files to have consistent object_ and mball_ prefix:
object_shapekey.c, object_lattice.c, object_vgroup.c, mball_edit.c.
* Added operators:
* vertex group menu and set active
* apply location, rotation, scale, visual transform (location is new)
* make local
* make vertex parent
* move to layer
* convert to curve/mesh (not finished yet)
* Many small fixes for marked issues, but still much code to be cleaned
up here...
* Objects now support up to 32767 material slots. It's easy to
increase this further, but I prefer not to increase the memory
usage of mesh faces, it seems unlikely that someone would
create 32767 distinct materials?
* Forward compatibility: the only thing you can potentially lose
reading a 2.5 file in 2.4 is object linking (instead of default
data), though usually that will go fine too. Reading files with
> 32 material slots in 2.4 can start giving issues.
* The ob->colbits variable is deprecated by the array ob->matbits
but I didn't remove the ob->colbits updates in very few places
it is set.
* I hope I changed all the relevant things, various places just
hardcoded the number 16 instead of using the MAXMAT define.
* Join Objects operator back. This is using the version from the
animsys2 branch coded by Joshua, which means it now supports
joining of shape keys.
* Fix for crash reading file saved during render.
* 3D view Mesh menu works again, but incomplete.
* Add Properties and Toolbar to 3D View menu.
* Added "specials" menus back, vertex/edge/face and general.
* Various fixes in existing mesh operators, some were not working.
* Add MESH_OT_merge.
* Merge all subdivide ops into MESH_OT_subdivide, subdivide code
changes to make smooth + multi give good results.
* Rename all select inverse ops to *_OT_select_inverse.
* Fix "search for unknown operator" prints at startup, and some
warnings in py code.
* Don't run .pyc files on startup.
* Remove unused image window header C code.
RNA
* Added the relevant active_*_index properties, with proper
get/set/range, updates and notifiers.
* Context.tool_settings.
* ToolSettings.vertex_group_weight.
Operators
* MESH_OT_uv_texture_add/remove
* MESH_OT_vertex_color_add/remove
* MESH_OT_sticky_add/remove
* OBJECT_OT_vertex_group_add/remove/assign/remove_from/
select/deselect/copy/copy_to_linked
* OBJECT_OT_shape_key_add/remove
UI
* Some updates and cleanups in list template code.
Known issue: when going in & out of editmode, uv textures and vertex
colors dissappear. I thought me->edit_mesh would be NULL when not in
edit mode but it is not?
