[Soc-2013-dev] Weekly Report #13 Threaded Dependency Graph

[Sergey Sharybin]

Hi,

>From code side there were changes all over the place:

- Bug fixes in motion tracking area.
- Film response curves implemented as a looks.
- Enable vertex snapping to bundle positions.
- Create/delete keyframe for motion tracks in clip editor.
- Tweaks to plane track after getting artists' feedback.
- Lock-free memory overhead-less guarded allocator is finally in the svn
(in my branch, not in trunk yet).
- Fix #36701: Mask pivioting doesnt honor parenting

Some of the changes were needed to make current tracking ready for the
release, some of them were just general improvements.

As for the threaded dependency graph, spent some time writing
documentation, see here. Did some smaller speed improvements to subsurf
code.

Most of the time was spent on the local graphs and data/state separation.
For now conclusion is: copy-on-write is the way to go. Documentation is not
finished, will finish it and send to all related developers for final
review.

= Next week =

Next week is for finishing COW proposal, warping up the code, finishing
documentation.

= Questions =

None at this point, had loads of help from Brecht brainstorming local graph
ideas already :)

With best regards, Sergey Sharybin
