[#20854] PROPERTIES STAMP: Rendering stamp flickers in output renders
Blenfont was not thread safe, that is why one thread can change
the font properties (size, dpi, color, etc) at the same time
that the stamp draw on the image, and then the problem.
To make blenfont thread safe I have to change two important things:
1) Every BLF_* function take one argument, the font id.
2) We have two new function to make font "thread safe":
BLF_load_unique
BLF_load_mem_unique
This two function are for case like stamp, that need and own font
that don't share the glyph cache, so can draw without problem
in a different thread.
Why the BLF_*_unique function ?
Because blenfont keep only one copy of a font and keep a list of
"glyph cache". Every glyph cache have size and dpi, so if two
different thread access the same font at the same time, they can
change value and finish with something like the stamp problem.
Why don't remove the glyph cache ?
Because if we do that, we finish with a font object for every size
and dpi, and the stamp is really a special case that happen in
the rendering process, so I really thing is better keep the
glyph cache and make this two new function to handle this
special case.
(When I say "font object" I mean have the same freetype font multiple
times just to have differents size and dpi)
As Matt point we still can have one case that two thread access
the BLF_*_unique function at the same time, but I am looking to
fix this with some class of thread lock.
For now I test and work fine, so if some one found problem, please
let me know.
Campbell I have to change the python api (python/generic/blf_api.c)
to the new syntax, so maybe you can take a look at this.
Made texture/texture slot context a bit less flaky when dealing with active material and
texture nodes inside a node material in the node editor. Now if the active material has
nodes enabled, and there are no active material/texture nodes inside it, nothing will be
shown in the texture properties (similar to 2.49).
Previously all modifier operators relied on the buttons layout data context pointer to
decide which modifier to work on. This meant that these operators would only work
from from the properties panel, and not from scripting/macros or for operator redo.
This commit makes all modifier operators take the modifier name as an operator
property, so the operators can be re-done or executed outside of the modifier panel.
When invoking the operators from the modifier panel, they automatically fill in the
operator property from context.
This isn't a perfect API design, but it does bring these operators in line with the design
of being able to access all UI functionality via other means like scripts.
Bone would get a '.' added even when there was no extension.
(center limit would still be useful)
- name flipping function used sizeof() incorrectly.
- ED_lorem should be extern.
- collada export would run MEM_freeN on an un-initialized pointer in some cases.
- makesrna was missing a call to close a file.
- text cursor update function was missing a NULL check for st->text.
- possible (unlikely) un-initialized return value for bge python lamp.type, set error instead.
- possible (unlikely) missing NULL terminator with strncpy for ffmpeg.
- BGE Shader.setSampler(name, index): index range check was wrong.
- Compositor check for an invalid channel was incorrect.
- getting the center of selected verts used an uninitalized z axis.
- do_init_render_material() used && rather then & when testing for MA_TRANSP.
- weight paint activate flipped bone used && rather then & for flag checking.
* Division by zero fix for TNT SVD code.
* Sound fix, in case ffmpeg decode fails, don't use the samples.
* Fix for incorrect bounds of transformed objects in new raytracing code.
* Gave memory arena's a name used for allocations for easier memory
usage debugging.
* Dupligroup no_draw option was using layers but not restrict view/render
setting. (not a bugfix exactly but would do display list context switching
while drawing for no reason).
* Fix objects instanced on hair particles not giving consistent results
when the object is transformed.
* New math functions: madd_v4_v4fl, len_squared_v3v3, interp_v4_v4v4v4,
mul_v4_m4v4, SH and form factor functions, box_minmax_bounds_m4.
* mul_m4_m4m4 and mul_m3_m3m3 now accept the same pointers for multiple
arguments.
* endjob callback for WM jobs system.
* Geometry node uv/color layer now has search list/autocomplete.
* Various small buildsystem tweaks, not strictly needed yet in trunk.
* The test is now only done when some object that uses cache has actually changed.
* The added scene->physics_settings->quick_cache_step is only an internal counter, not a user changeable value.
multires modifier if both are in the stack (patch #21965)
This patch also removes limitation of multires reshaping when
destination object has got modifiers after multires modifier.
* Increasing subframe count increases stability for SPH fluid and Newtonian particles
* Also small tweaks into physics ui panel to better fit new subframes value
* This commit also fixes the moving fluid emitter problem as described by Raul in the mailinglist
patch by Ben Batt (artificer)
Updated patch for 6 or so modifiers added since the patch was written.
- tested with CMake and SCons
- fixed one error were flags were being added to the fluids type.
- remove BKE_simple_deform.h, simple_deform.c, move functions into MOD_simpledeform.c since there were problems with circular deps.
- moved some fluid and boolean functions used by modifiers too.
Made custom proxy files a lot more sensible to select
(upgraded to filepath get/setters)
Changed semantics, since custom files don't make much
sense without custom directories...
- vertex normals were not being flipped (though faces are)
- rim faces didnt influence edge vertex normals
apply solidify on top of solidify modifier now works correctly
- convert solidify edge crease values into chars once rather then for each edge.
- sort vertex was checking the array all the time when it wasnt needed.
- Disallow this and report a warning in the console when it happens.
- File selector operators now report in the global report console.
- Cleared some warnings.
* Made it use the temp directory in user preferences when the .blend file hasn't been saved yet
* Made bmain->name (wrapped as bpy.data.filename) contain an empty string when
there's no .B25.blend and no file saved, rather than "<memory2>".
This is a good candidate for consistent file path api, retrieving temp dirs / project-
specific temp dirs / etc...
* The new default particle size is quite small, so exploded pieces didn't match the original pieces
* There's now an option to use the particle size (useful for some effects), but it isn't used by default
* This commit will change how some old files look (explode modifier and not 1.0 particle size), but the exact old behavior is achieved with the new "size" option

This adds the waveform monitor and vectorscope to the image editor 'scopes'
region, bringing it inline (plus a bit more) with sequence editor functionality,
and a big step closer to the end goal of unifying the display code for image/
comp/sequence editor. It's non-intrusive, using the same code paths as
the histogram.
There's still room for more tweaks - I modified the original patch, changing
the openGL immediate mode drawing of the waveform display to vertex arrays for
speed optimisation. Xavier can look at doing this for the vectorscope now too.
Thanks very much Xavier!

note from the submission
-snip-
While in there I removed the Win32 conditionals that made "_strdate" used to
get date on Windows. "localtime" works fine on Windows so the results are consistent on all platforms.
This patch add SPH (Smoothed Particle Hydrodynamics)fluid dynamics to the
blender particle system. SPH is an boundless Lagrangian interpolation
technique to solve the fluid motion equations.
From liquids to sand, goo and gases could be simulated using the particle
system.
It features internal viscosity, a double density relaxation that accounts
for surface tension effects, static internal springs for plastic fluids,
and buoyancy for gases.
---------------------------------------
This is a commit of the core fluid physics. Raul will work on proper
documentation soon and more features such as surface extraction from
the particle point cloud and increasing stability by sub-frame calculations
later.
I removed 3D flag checking for DL_POLY displists in nurbs-to-mesh conversion
function -- DL_POLY displist should be always converted to edge loop.
DL_POLY which should be converted to something else is odd i think.
This commit also fixes trouble cyclic surface curve to mesh conversion problem.
