Fix T41144
|

- Forgot to handle command line arguments
- Because of the fact we need to be able to
use stdout and stderr we need to use regular
console application for the wrapper.
- Because of using regular application for the
wrapper we need to check forparent PID in the
isStartedFromCommandPrompt().
I really hope it's not gonna to become any more
complicated.

Main idea of this change is to make a small executable which
will set OMP_WAIT_POLICY environment variable and then will
launch blender itself.
This is a teporary solution for the time being we'll have a
more clear solution to high CPU usage with OpenMP when building
with MSVC.

Couple of issues:
- Debian systems doesn't use site-packages but uses
dist-packages instead.
- Requetss from ubuntu repository depends on urlllib3
and chardet, which also implies six. copy those libs
as well.
I know it's all rather annoying, but no that much
choise is in here..

This solves missing requests package reported on the systems where it's
located in dist-packages rather than in site-packages.
To do this there's now a helper macros which handles both requests and
numpy now and could be used for more packages in the future.

This is needed because render threads would do some allocations like
part buffer allocation and so. This is likely harmless with the lock
free allocator (not on Windows tho), but when using guarded allocator
we need to be sure access to the list of MemHead is safe.

Current temporary data of Blender suffers one major issue - default 'temp' dir on Windows is never
automatically cleaned up, and can end being quite big when used by Blender, especially when we have
to store per-process data (using getpid() in file names).
To address this, this patch:
* Divides tempdir paths in two, one for 'base' temp dir (the same as previous unique tempdir path),
the other is a mkdtemp-generated sub-dir, specific to each Blender instance.
* Only uses base tempdir when we need some shallow persistance accross Blender sessions - and we always
reuse the same filename (quit.blend...) or generate small file (crash reports...).
* Uses temp sub-dir for heavy files like pointcache or renderEXRs (Save Buffer option).
* Erases temp sub-dir on quit or crash.
To get this working it also adds a working 'recursive delete' to BLI_delete() under Windows.
Note that, as in current code, the 'recover render result' hack-feature that was possible
with SaveBuffer option is still removed. A real renderresult cache feature will be added
soon, though.

Needed to make the blender link libraries a global property
now that tests are parallel to source directory.
Current sort order for blender link libraries doesn't work
for tests that start with few defined symbols. Doubling the
lib list works, but a TODO to find a better way (probably
using CMake's own mechanism for tracking dependencies).
|
|
Currently covers only small set of functionality.

Opted to keep includes if they are used indirectly (even if removing is possible).
|

There is not much sense to have a whole BLI file just to check SSE2 on CPUs...
So idea is to rename it to more generic "BLI_system", and add to it more system-related
utils, like e.g. an include helper for getpid(), which allows to hide unix/windows
internals from rest of the code...

Fixes T39423: Blender crashes on iv41 encoded videos in thumbnail display mode
Libraries are still being committed to the svn, so compilation might be broken
for a while. Sorry for this, but can't really be avoided.
Also, some typos in scons are possible.

in threaded depgraph updates and effector list construction.
Gathering effectors during depgraph updates will call the
psys_check_enabled function. This in turn contained a DNA alloc call
for the psys->frand RNG arrays, which is really bad because data must be
immutable during these effector constructions.
To avoid such allocs the frand array is now global for all particle
systems. To avoid correlation of pseudo-random numbers the psys->seed
value is complemented with random offset and multiplier for the actual
float array. This is not ideal, but work sufficiently well (given that
random numbers were already really limited and show repetition quite
easily for particle counts > PSYS_FRAND_COUNT).

The documentation for the -b/--background option incorrectly states that it
takes a <file>, however it can run also without a file with e.g. a script.

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.

Patch D123 from djnz (Masakazu Ito)
|
|
The problem is that the animation curves are first before object updates,
where BKE_pose_rebuild and proxy synchronize will undo the animation when the
proxy is evaluted for the first time after loading.
This is somewhat of a workaround but it's also useful to have the scene updated
once when opening in background mode, and it makes rendering from the UI and
background more similar and so more predictable to give the same result.
