Calling `finish` after writing to generic attributes is currently necessary for
correctness. Previously, this was easy to forget. Now there is a check for this
in debug builds.
|
|
The data has been moved somewhere else, the span should not
keep a pointer to it.
|
|
`GSpan` and spans based on virtual arrays were not default constructible
before, which made them hard to use sometimes. It's generally fine for
spans to be empty.
The main thing the keep in mind is that the type pointer in `GSpan` may
be null now. Generally, code receiving spans as input can assume that
the type is not-null, but sometimes that may be valid. The old #type() method
that returned a reference to the type still exists. It asserts when the
type is null.

This is just a theoretical improvement currently, I won't try to justify
it with some microbenchmark, but it should be better to use the
specialized single and span virtual arrays when slicing a `GVArray`,
since any use of `GVArrayImpl_For_SlicedGVArray` has extra overhead.

* Make the class names more consistent.
* Implement missing move-constructors and assignment-operators.
|
|
|
|
This reduces the amount of code, and improves performance a bit by
doing more with less virtual method calls.

My benchmark which spend most time preparing function parameters
takes `250 ms` now, from `510 ms` before. This is mainly achieved by
doing less unnecessary work and by giving the compiler more inlined
code to optimize.
* Reserve correct vector sizes and use unchecked `append` function.
* Construct `GVArray` parameters directly in the vector, instead of
moving/copying them in the vector afterwards.
* Inline some constructors, because that allows the compiler understand
what is happening, resulting in less code.
This probably has negilible impact on the user experience currently,
because there are other bottlenecks.

Method which overrides a base class's virtual methods are expetced to
be marked with `override`. This also gives better idea to the developers
about what is going on.
|
|
This does two things:
* Introduce new `materialize_compressed` methods. Those are used
when the dst array should not have any gaps.
* Add materialize methods in various classes where they were missing
(and therefore caused overhead, because slower fallbacks had to be used).

In a test file from T96282, this commit reduces the runtime of the
delete geometry node from 82 ms to 23 ms, a 3.6x improvement.
Writing to vertex groups in other cases should be faster too.
The largest improvement comes from not writing a new weight
of zero if the vertex is not in the group. This mirrors the behavior
of custom data interpolation in `layerInterp_mdeformvert`.
Other improvements come from using `set_all` for writing
output attributes and implementing that method for vertex groups.
I also implemented `materialize` methods. Though I didn't obverse
an improvement from this, I think it's best to remove virtual method
call overhead where it's simple to do so.
The test file for the delete geometry node needs to be updated.
These methods could be parallelized too, but better to do that later.
