Summary:
Made objects update happening from multiple threads. It is a task-based
scheduling system which uses current dependency graph for spawning new
tasks. This means threading happens on object level, but the system is
flexible enough for higher granularity.
Technical details:
- Uses task scheduler which was recently committed to trunk
(that one which Brecht ported from Cycles).
- Added two utility functions to dependency graph:
* DAG_threaded_update_begin, which is called to initialize threaded
objects update. It will also schedule root DAG node to the queue,
hence starting evaluation process.
Initialization will calculate how much parents are to be evaluation
before current DAG node can be scheduled. This value is used by task
threads for faster detecting which nodes might be scheduled.
* DAG_threaded_update_handle_node_updated which is called from task
thread function when node was fully handled.
This function decreases num_pending_parents of node children and
schedules children with zero valency.
As it might have become clear, task thread receives DAG nodes and
decides which callback to call for it.
Currently only BKE_object_handle_update is called for object nodes.
In the future it'll call node->callback() from Ali's new DAG.
- This required adding some workarounds to the render pipeline.
Mainly to stop using get_object_dm() from modifiers' apply callback.
Such a call was only a workaround for dependency graph glitch when
rendering scene with, say, boolean modifiers before displaying
this scene.
Such change moves workaround from one place to another, so overall
hackentropy remains the same.
- Added paradigm of EvaluaitonContext. Currently it's more like just a
more reliable replacement for G.is_rendering which fails in some
circumstances.
Future idea of this context is to also store all the local data needed
for objects evaluation such as local time, Copy-on-Write data and so.
There're two types of EvaluationContext:
* Context used for viewport updated and owned by Main. In the future
this context might be easily moved to Window or Screen to allo
per-window/per-screen local time.
* Context used by render engines to evaluate objects for render purposes.
Render engine is an owner of this context.
This context is passed to all object update routines.

This attribute allows to open a blend file as an alternative
start-up file. The attribute is only available from python.
This is an example call:
bpy.ops.wm.read_homefile(filepath='path/to/a/file.blend')
This patch also changes readfile.c to ensure that unintentionally
stored cursor states are not imported from the loaded file.
* Update readme for 2.70 (content + links), also updates for new tracker/git.
* Fix some links to the new blender.org website
* Release logs now point directly to the wiki, I don't see a reason to point to the website, just to redirect to the wiki after all.
Summary:
Old idea with changes since previous release tag
didn't work good enough. In most of the cases tag
was done in a branch hence not actually reachable
from the master branch.
Now change since release is gone, and date of
the latest commit is used instead.
The date is displayed in format YYYY-MM-DD HH:mm
in the splash.
New bpy.app fields:
- build_commit_timestamp is an unix timestamp of
the commit blender was build from.
- build_commit_date is a date of that commit.
- build_commit_time is a time of that commit.

Circle select was missing from node editor, and C key was assigned to now defunct "show cyclic dependencies". This patch remaps the key and adds circle select operator.
Functions to check intersection between rctf/rcti and a circle were also added to rct.c for code cleanliness and consistency.
- Use commit number since last annotated tag as a
revision number replacement. It'll eb followed
by 'M' symbol if there're local modification in
the source tree.
- Commit short SHA1 is included. Helps getting
information about commit used to build blender
with much faster.
- If build is not done from master branch, this also
will be noticed in the splash screen.
This commit also replaces revision stored in the
files with git-specific fields (change and hash).
This is kind of breaks compatibility, meaning
files which were saved before this change wouldn't
display any information about which revision they
were saved with. When we'll finally switch to git,
we'll see proper hash and change number since
previous release in the files, for until then
svn version will be used as a change number and
hash will be empty.
Not a huge deal, since this field was only used
by developers to help torubleshooting things and
isn't needed for blender itself.
Some additional tweaks are probably needed :)
When printing operator reports, ommit unset properties.
This is needed because in some cases operators check if a value is set or not, so filling in default arguments may change behavior.
curves and metaballs now behave the same as meshes wrt grid scaling.
remove WM_operator_view3d_distance_invoke(), and replace with a function called from exec which initializes defaults, this way operators can have their own invoke functions.
when running viewport operations with exec() rather then invoke(), perform the action immediately rather then using smoothview.
makes viewport operations usable from python scripts.
- add missing headers from cmake (own omission)
- quiet rna_test.c unused define warnings.
- minor style edits
- spelling corrections and ignore all uppercase words with spell checking script.
rotation of the brush mask texture.
Unfortunately secondary path does not work here because we do not have a
permanent switch to choose between primary-secondary brush texture. Use
operator property instead.
