This commit integrates the work done so far on the new dependency graph system,
where goal was to replace legacy depsgraph with the new one, supporting loads of
neat features like:
- More granular dependency relation nature, which solves issues with fake cycles
in the dependencies.
- Move towards all-animatable, by better integration of drivers into the system.
- Lay down some basis for upcoming copy-on-write, overrides and so on.
The new system is living side-by-side with the previous one and disabled by
default, so nothing will become suddenly broken. The way to enable new depsgraph
is to pass `--new-depsgraph` command line argument.
It's a bit early to consider the system production-ready, there are some TODOs
and issues were discovered during the merge period, they'll be addressed ASAP.
But it's important to merge, because it's the only way to attract artists to
really start testing this system.
There are number of assorted documents related on the design of the new system:
* http://wiki.blender.org/index.php/User:Aligorith/GSoC2013_Depsgraph#Design_Documents
* http://wiki.blender.org/index.php/User:Nazg-gul/DependencyGraph
There are also some user-related information online:
* http://code.blender.org/2015/02/blender-dependency-graph-branch-for-users/
* http://code.blender.org/2015/03/more-dependency-graph-tricks/
Kudos to everyone who was involved into the project:
- Joshua "Aligorith" Leung -- design specification, initial code
- Lukas "lukas_t" Toenne -- integrating code into blender, with further fixes
- Sergey "Sergey" "Sharybin" -- some mocking around, trying to wrap up the
project and so
- Bassam "slikdigit" Kurdali -- stressing the new system, reporting all the
issues and recording/writing documentation.
- Everyone else who i forgot to mention here :)

CCFLAGS are used for both C and C++ compilers and one is better not to pass
C-related flags to C++ compiler. C-compiler flags are to be passed via CFLAGS
variable.

GCC5 defaults to gnu11, which we may switch to later
but disable for now to prevent accidental use.

This commit makes some preliminary fixes and tweaks aimed to make blender
compilable with C++11 feature set. This includes:
- Build system attribute to enable C++11 featureset.
It's for sure default OFF, but easy to enable to have a play around with
it and make sure all the stuff is compilable before we go C++11 for real.
- Changes in Compositor to use non-named cl_int structure fields.
This is because __STRICT_ANSI__ is defined by default by GCC and OpenCL
does not use named fields in this case.
- Changes to TYPE_CHECK() related on lack of typeof() in C++11
This uses decltype() instead with some trickery to make sure returned type
is not a reference.
- Changes for auto_ptr in Freestyle
This actually conditionally switches between auto_ptr and unique_ptr since
auto_ptr is deprecated in C++11. Seems to be not strictly needed but still
nice to be ready for such an update anyway/
This all based on changes form depsgraph_refactor branch apart from the weird
changes which were made in order to support MinGW compilation. Those parts of
change would need to be carefully reviewed again after official move to gcc49
in MinGW.
Tested on Linux with GCC-4.7 and Clang-3.5, other platforms are not tested and
likely needs some more tweaks.

We need to register the exception handler slightly differently here, as
well as adding DbgHelp as a library, but according to docs it should be
supported in recent Windows editions (Win XP included even).
We can try it first and revert if there are issues.
|

So, it turns out my changes here the other day were a bit too over-eager:
-Wdeclaration-after-statement and -Wstrict-prototypes only applied to C code
and not C++ (which that set of flags was getting included for too).
However, -Wno-char-subscripts is fine where it is now, so I've left it in place

Doesn't mean we're 100% ready for the transition, but need to start somewhere
anyway. Changes:
- OSL is no longer supporting cpp and requires usage of Boost Wave.
So now Wave component of Boost is optionally demanded when looking for the
Boost libraries if OSL is enabled.
Only did this for Linux, MSVC seems already using Wave. Not sure about OSX.
- Because of the same reason OSL should be moved prior Boost for linker.
- Whole archive trick makes it so linking fails with duplicated symbols, so
removed it for the new OSL. Didn't see issues with this so far.
- Added some code to check OSL version on Linux. Would need to move all that
to FindOpenShadingLanguage.cmake which we can get from Cycles standalone
repository.
So in theory no affect on current stup would be made at all.
- Added some tweaks to buildbot files. It now seems to be happy with the new
OSL libraries, but again, those tweaks are not in action yet.
All this was tested on Linux only. Win/OSX might still need some tweaks to
support new OSL.
P.S. This doesn't mean we're pushing OSL update yet, just making some
preliminary tweaks to avoid entropy of PITA when we'll actually want to
switch.

The warning flags in C_WARN were not actually getting included
(most notably, the one disabling the pointless + braindead one
about using chars to index into arrays - given that we only use
unsigned chars everywhere). Maybe this should get done for the
other scons platforms too?

- fix dead blender.org link (build dependencies)
- rewrite $BLENDERHOME/{config,tools}/* to $BLENDERHOME/build_files/scons/{config,tools}/*

They're not intended to be executed directly and seems mode change happened
by accident.
Setting -x for this files to avoid possible incidents by trying to run this
files in shell.

Original patch by @random (D765) with some minor work done by @campbell
and me.
At this place, I'd like call out a number of people who were involved and
deserve a big "Thank you!":
* At the first place @randon who developed and submitted the patch
* The Blendercn community which helped a lot with testing - espacially
* @yuzukyo, @leon_cheung and @kjym3
* @campbellbarton, @mont29 and @sergey for their help and advises during
* review
* @ton who realized the importance of this early on and asked me for
* reviewing
We are still not finished, as this is only the first part of the
implementaion, but there's more to come!

This actually enables it in the darwin scons config, that's how it always
used to be configured there.
|
|
Default configuration already includes libmv and glog, so all
the dependencies are met. And logging is nice to have anyway.
This wouldn't give any slowdown, because all the logging is
silenced unless '--debug-cycles', plus no logging is done
from the speed critical code.

Basically, title says ti all, the option is called WITH_BF_CYCLES_LOGGING

This is mainly to address old issue when one need to have SDL library installed
in order to use our official builds. Some hip distros already installs SDL,
but it's not quite the same across all the variety of the distros.
We also now switching to SDL-2.0, most of the distros have it in repositories
already, so it shouldn't be huge deal to install it if needed.

@loader_path/../Resources/lib/libiomp5.dylib
This makes install_name_tool usage obsolete here and also assures cmake builds can be codesigned.
IMPORTANT: update lib (darwin-9.x.universal/openmp)

This was already disabled in CMake and we need to keep build systems
in 100% synchronized state.
P.S. Would it be a real fix to drop SCons?

This reverts commit cdf53701599ace0b3410cbb75b0313bd969c417c.
Please always keep build-systems simple, boring & functional,
anyone who liked notification popups can write a simple build script.

Separates graphics context creation from window code in Ghost so that they can vary separately.

Currently only summed number of traversal steps and intersections used by the
camera ray intersection pass is implemented, but in the future we will support
more debug passes which would help checking what things makes the scene slow.
Example of such extra passes could be number of bounces, time spent on the
shader tree evaluation and so.
Implementation from the Cycles side is pretty much straightforward, could only
mention here that it's a build-time option disabled by default.
From the blender side it's implemented as a PASS_DEBUG with several subtypes
possible. This way we don't need to create an extra DNA pass type for each of
the debug passes, saving us a bits.

This way folks with few ram or those who wants to hack into Ceres
code might compile Blender much faster.

|
Also move this to a generic place in SConstruct instead of having this
defines in 6 different configurations.
Should not be functional changes, but please verify all the platforms.
|
|
Probably the vc2013 builder can become a more generic name now, but I will double check this with Martijn.
|
|
|
|
Since we have older llvm for msvc2008 and new one for msvc2013 we need to work around it.
