Testing for custom data availability with getVertData and index 0 fails
on assert for empty meshes (the index must be in valid range). Better
use getVertDataArray which has no requirement for specific index.
The problem is that comparisons involving the constants Nature.POINT (for vertices) and
Nature.NO_FEATURE (for edges) were evaluated in a wrong way. It is recalled that the
Nature class is a subclass of Python's built-in int type, and that these two constants are zero
when evaluated as numbers. The issue was caused by the implementation of the constants
in an incompatible way for comparison with Python int (and boolean) values. Specifically,
the zero of Python int is represented by an empty array of digits, whereas the zero-valued
Nature constants were represented by an array of size 1. Python int comparison operators
first check the lengths of the arrays of two operands, and then start comparing the digits
only when the array length is the same. For this reason, the two Nature constants were
not properly compared with int values (and thus with boolean values). It is noted that the
zero-valued Nature constants may result from bitwise operations on other Nature constants
(e.g., Nature.SILHOUETTE & Nature.BORDER), so this issue must have affected many
existing style modules.
The problem was reported by Folkert de Vries (flokkievids) through personal communications.
Thanks a lot!
Last change to bevel had a check for what was supposed
to be an "on edge" new vertex being off the edge.
The test tolerance was too small. This fixes that.
This made loops in linked lists of uvedges from duplicate members
causing a hang. Now check all previous links before adding a new one. It
is not much slower in practice because non-manifolds are not that
frequent.
to wrong obmats of nested dupli objects.
Restoring obmats after BI nested dupli object rendering has to happen
in reverse order, so higher level omats are applied last.
If you have two overlapping NLA strips it automatically blends between them.
However it was also blending between the first strip and the rest pose
(e.g. 0,0,0 for locations and 1,1,1 for scale).
This is ok if the blend mode is Add or Multiply since then you are adding onto
the rest pose, but for Replace you want to be able to mix between two poses
and not take the rest pose into account at all.
What this does is that to not do any blending for the first strip if it has
blend mode Replace. If someone wants the old behavior (from bugfix commit
27d792fa9c) they can still make an action with the rest pose and use that
as the first strip.
Grease pencil straight line can still be enabled by first pressing D
then Ctrl and looks like there is no final consensus on key shortcut.
Better leave this as before and solve after release.
Implements a more flexible internal connect function for standard nodes
(compositor, shader, texture). Allow feasible datatype connections by
priority.
The priorities for common datatypes in compositor, shader and texture
nodes are encoded in a simple function. Certain impossible connections
(e.g. color -> cycles shader) are excluded by giving them -1 priority.
Priority overrides link status: If a higher priority input can be found,
this will be used regardless of link status. Link status only comes into
play for inputs with same priority.

Issue of this bug is that most part of fftw is not thread safe, only compute-intensive fftw_execute & co are.
Since smoke was affected by this issue as well, a global fftw mutex was added to BLI_threads.
Audaspace also uses fftw in one of its readers (AUD_BandPassReader.cpp),
but this is not an issue currently since this code is disabled in CMake/scons files.
There was another threading issue with smoke, we need to copy dm used by emit_from_derivedmesh(),
as it is modified by this func.
