Caused by f1c0249f34, which filled the wrong value.
I have noticed several problems:
- Using a full array as single result.
- Checking single material index for 0. If we have a list of all slots,
then we must check this in the list.
- The result was filled false. Simple fix.
- Fixed problem with incorrect recording by mask indices, not polygons.
- Added domain specifics to names to avoid confusion.

Improve animation playback performance in EEVEE for materials using Mix
nodes. Socket availability was being set and reset on every evaluation
of Mix nodes, during animation playback, this was causing the graph to
be marked dirty, and the whole graph being re-evaluated on every frame,
causing performance issues during playback.
Additionally, do a bit of cleanup, traversing the node sockets with
the next link to improve clarity and reduce errors. Also refactoring
`nodeSetSocketAvailability` to early out and increase clarity on no-op.

This patch allows the realtime compositor to be limited to a specific
compositing region that is a subset of the full render region. In the
context of the viewport compositor, when the viewport is in camera view
and has a completely opaque passepartout, the compositing region will be
limited to the visible camera region.
On the user-level, this gives the user the ability to make the result of
the compositor invariant of the aspect ratio, shift, and zoom of the
viewport, making the result in the viewport identical to the final
render compositor assuming size relative operations.
It should be noted that compositing region is the *visible* camera
region, that is, the result of the intersection of the camera region and
the render region. So the user should be careful not to shift or zoom
the view such that the camera border extends outside of the viewport to
have the aforementioned benefits. While we could implement logic to fill
the areas outside of the render region with zeros in some cases, there
are many other ambiguous cases where such a solution wouldn't work,
including the problematic case where the user zooms in very close,
making the camera region much bigger than that of the render region.

Previously, the lifetimes of anonymous attributes were determined by
reference counts which were non-deterministic when multiple threads
are used. Now the lifetimes of anonymous attributes are handled
more explicitly and deterministically. This is a prerequisite for any kind
of caching, because caching the output of nodes that do things
non-deterministically and have "invisible inputs" (reference counts)
doesn't really work.
For more details for how deterministic lifetimes are achieved, see D16858.
No functional changes are expected. Small performance changes are expected
as well (within few percent, anything larger regressions should be reported as
bugs).

This is part of D16858. Iterating over all field inputs allows us to extract
all anonymous attributes used by a field relatively easily which is necessary
for D16858.
This could potentially be used for better field tooltips for nested fields,
but that needs further investigation.
This is part of D16858 but is also useful for other purposes.
The changes to the node declaration in this commit allow us to figure
out which fields might be evaluated on which geometries statically (without
executing the node tree). This allows for deterministic anonymous attribute
handling, which will be committed separately. Furthermore, this is necessary
for usability features that help the user to avoid creating links that don't
make sense (e.g. because a field can't be evaluated on a certain geometry).
This also allows us to better separate fields which depend or don't depend
on anonymous attributes.
The main idea is that each node defines some relations between its sockets.
There are four relations:
* Propagate relation: Indicates that attributes on a geometry input can be
propagated to a geometry output.
* Reference relation: Indicates that an output field references an inputs field.
So if the input field depends on an anonymous attribute, the output field
does as well.
* Eval relation: Indicates that an input field is evaluated on an input geometry.
* Available relation: Indicates that an output field has anonymous attributes
that are available on an output geometry.
These relations can also be computed for node groups automatically, but that
is not part of this commit.
When these declarations are built without the help of the special
builder class, it's much more convenient to set them directly rather
than with a constructor, etc. In most other situations the declarations
should be const anyway, so theoretically this doesn't affect safety too
much. Most construction of declarations should still use the builder.
Whenever a node group is entered during evaluation, a new compute
context is entered which has a corresponding hash. When node groups
are entered and exited a lot, this can have some overhead. In my test
file with ~100.000 node group invocations, this patch improves performance
by about 7%.
The speedup is achieved in two ways:
* Avoid computing the same hash twice by caching it.
* Invoke the hashing algorithm (md5 currently) only once instead of twice.
Geometry nodes used to log all socket values during evaluation.
This allowed the user to hover over any socket (that was evaluated)
to see its last value. The problem is that in large (nested) node trees,
the number of sockets becomes huge, causing a lot of performance
and memory overhead (in extreme cases, more than 70% of the
total execution time).
This patch changes it so, that only socket values are logged that the
user is likely to investigate. The simple heuristic is that socket values
of the currently visible node tree are logged.
The downside is that when the user changes the visible node tree, it
won't have any logged values until it is reevaluated. I updated the
tooltip message for that case to be a bit more precise.
If user feedback suggests that this new behavior is too annoying, we
can always add a UI option to log all socket values again. That shouldn't
be done without an actual need though because it takes up UI space.
Differential Revision: https://developer.blender.org/D16884
Use socket indices to keep track of logged values instead of their
identifiers. This decreases memory pressure when there are many
sockets. In cases with many cheap nodes, this can give a relatively
large improvement to overall performance. We observed a 15% increase
in a case with many math nodes and a larger increase in an experimental
softbody node setup. The log is invalidated when we add/remove/move
sockets anyway.
This is the best way I found to make building socket declarations without
the builder helper class work. Besides a vague hope for non-leaky
abstractions, I don't think there's any reason for these fields not to be
accessible directly.

The node doesn't support blurring boolean attributes, so avoid
compiling an implementation for boolean data.
Differential Revision: https://developer.blender.org/D16867
Separate the "insert nodes into group" operation into more distinct
phases. This helps to clarify what is actually happening, to avoid
redundant updates to group nodes every time a new socket is discovered,
and to make use of the topology cache to avoid the "accidentally
quadratic" alrogithms that we have slowly been removing from node
editing.
The change is motivated by the desire to use dynamic node declarations
for group nodes and group input/output nodes, where it is helpful to
avoid updating the declaration and sockets multiple times.
Caused by b08301c865. This also contains an optimization
compared to the previous version to avoid recalculating normals when
the entire mesh has moved by the same offset.

This patch implements the Streaks Glare node. Which is an approximation
to the existing implementation in the CPU compositor. The difference due
to the approximation is bearily visible in artificial test cases, but is
less visible in actual use cases. Since the difference is rather similar
to that we discussed in the Simple Star mode, the decision to allow that
difference would probably hold here.
For the future, we can look into approximating this further using a
closed form IIR recursive filter with parallel interconnection and
block-based parallelism. That's because the streak filter is already
very similar to the causal pass of a fourth order recursive filter,
just with exponential steps.

This patch implements the variable size mode of the blur node. This is
not identical to the CPU implementation, but is visually very close.
That's because of two things. First, the Extend Bounds option introduces
a 2px offset that doesn't make sense, which is likely a bug in the CPU
implementation. Second, the CPU implementation approximate the result
using three passes, the first two of which are separable morphological
operators applied on the size input. But this approximation does not
provide an advantage because the last pass is non-separable anyways. So
the GPU implementation does not attempt this approximation for more
accurate and faster results.

Previously, the code tried to keep node groups working even if some of
their input/output sockets had undefined type. This caused some
complexity with no benefit because not all places outside of this file
would handle the case correctly. Now node groups with undefined
interface sockets are disabled and have to be fixed manually before
they work again.
Undefined interface sockets are mostly caused by invalid Python
API usage and incomplete forward compatibility (e.g. when newer
versions introduce new socket types that the older version does
not know).

This adds a new mirror image extension type for shaders and
geometry nodes (next to the existing repeat, extend and clip
options).
See D16432 for a more detailed explanation of `wrap_mirror`.
This also adds a new sampler flag `GPU_SAMPLER_MIRROR_REPEAT`.
It acts as a modifier to `GPU_SAMPLER_REPEAT`, so any `REPEAT`
flag must be set for the `MIRROR` flag to have an effect.

This is essentially a left-over from the initial transition to fields where this was
forgotten. The mesh primitive nodes used to create a named uv map attribute
with a hard-coded name. The standard way to deal with that in geometry nodes
now is to output the attribute as a socket instead. The user can then decide
to store it as a named attribute or not.
The benefits of not always storing the named attribute in the node are:
* Improved performance and lower memory usage when the uv map is not
used.
* It's more obvious that there actually is a uv map.
* The hard-coded name was inconsistent.
The versioning code inserts a new Store Named Attribute node that
stores the uv map immediatly. In many cases, users can probably just
remove this node without affecting their final result, but we can't
detect that.
There is one behavior change which is that the stored uv map will be
a 3d vector instead of a 2d vector which is what the nodes originally created.
We could store the uv map as 2d vector inthe Store Named Attribute node,
but that has the problem that older Blender versions don't support this
and would crash immediately. Users can just change this to 2d vector
manually if they don't care about forward compatibility.
There is a plan to support 2d vectors more natively in geometry nodes: T92765.
This change breaks forward compatibility in the case when the uv map
was used.
Differential Revision: https://developer.blender.org/D16637
This allows choosing the 2d vector type in the Store Named Attribute
node. Similar to byte-colors, there is not a special socket type for this
(currently). In geometry nodes itself, vectors are all still 3d.
Recently a new geometry node for splitting edges was added in D16399.
However, there was already a similar implementation in mesh.cc that was
mainly used to fake auto smooth support in Cycles by splitting sharp
edges and edges around sharp faces.
While there are still possibilities for optimization in the new code,
the implementation is safer and simpler, multi-threaded, and aligns
better with development plans for caching topology on Mesh and other
recent developments with attributes.
This patch removes the old code and moves the node implementation to
the geometry module so it can be used in editors and RNA. The "free
loop normals" argument is deprecated now, since it was only an internal
optimization exposed for Cycles.
The new mesh `editors` function creates an `IndexMask` of edges to
split by reusing some of the code from the corner normal calculation.
This change will help to simplify the changes in D16530 and T102858.
