We have callbacks for that, they also do some checks and help ensure things are done
correctly. Only place where this is assumed not true is blenloader (since here we
may affect refcount of library IDs as well...).
Duplicate wasn't updating links,
so duplicatinvg a objects would still point to the originals for curve-taper, texmesh, drivers.
Use generic id-looper to handle replacing data.
- Add blentranslation `BLT_*` module.
- moved & split `BLF_translation.h` into (`BLT_translation.h`, `BLT_lang.h`).
- moved `BLF_*_unifont` functions from `blf_translation.c` to new source file `blf_font_i18n.c`.
Currently this function only tags pose itself, totally matching previous
behavior. But this will be needed in the future once new dependency graph
is landed, because of it's granular nature which relies on the fact that
pose channels are all up to date when building the graph.
Should be no functional changes so far.
The idea is pretty simple: instead of making temporary copy of all the
related custom data layers just pass the ownership from the DM to the
mesh.
This is really handy in cases when you've got DM which you need to
convert to Mesh datablock and wouldn't need that DM after conversion
anyway.
Foe example, render database conversion, exporters and even Modifier
Apply will benefit from this option.

* Same issue as T42760 was also reproducible in some cases in 3DView.
* You got an error message about missing RNA prop in some drop-called operators.
* You could not drop a movie file in nodes, (some cases of) 3DView, nor ImageEditor.
- Drawing grease pencil fail without scene-lock.
- Converting to curve failed without scene-lock.
- Outliner drag into viewport failed with local-view.
Non-mesh objects default to no collisions. lordloki provided a
patch that sets the collision properties for a mesh converted from
a curve/meta/surf/text to the default collision properties for
a mesh.
Changed curve active point from pointer to index. Allows curve active point to be saved to file and retained between modes for free. Also some small optimisations by removing pointer look up code.
- Made active point access functions into BKE API calls.
- Fixes operators where curve de-selection resulted in unsel-active point.
- Split curve delete into 2 functions
Previously this only worked for some datablocks relevant to rendering, now it
can be used to detect if any type of datablock was added or removed (but not
yet to detect if it was modified, we need many more depsgraph tags for that).
Most of the changes are some function parameter changes, the important parts
are the DAG_id_type_tag calls.

This goes back to ancient era again and such a call isn't
safe for threading and really DAG is to make it sure display
list for dependencies is always there.
Issue was introduced in a2bf25e and was caused by
do_makeDispListCurveTypes() no longer placing nurbs
to cu->nurb list.
Such an operation isn't thread-safe and proper solution
would require having granular update. For until them
just make object conversion take care of filling cu->nurb
in with splines from font.
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.
