The previous implementation of test_equal_ArrayHandles was several
templates that had to be resolved by any test that used them, which
could be costly for unknown array types. Simplify this a bit by moving
the implementation of testing unknown arrays into a library.
Another advantage of the new implementation is that is handles more
cases. Thus, you should not need to `ResetTypes` on the unknown/
uncertain arrays.
Some of the `test_equal` functions return a `TestEqualResult`
instead of a `bool` to capture more information about what
the error was. Unfortunately, using this was awkward because
you couldn't just call the `test_equal_*` inside of a
`VTKM_TEST_ASSERT`. Rather, you would have to do the comparison
and then check it.
This change adds an overload to `VTKM_TEST_ASSERT` that specifically
takes a `TestEqualResult`, checks its condition, and prints out
the contained messages. Thus, your command can just look like
`VTKM_TEST_ASSERT(test_equal_ArrayHandles(...));` and it will
provide the additional information.
These helper functions were in vtkm::cont::testing, but that made them
hard to discover (and I personally kept forgetting about them). Move
them to the top namespace so that IDE of test_equal will helpfully
remind us of these other test functions.
Recent merge requests !2354 and !2356 both edited ArrayHandleView. Git
successfully merged the changes, but the changes were still incompatible
with each other, causing an unexpected compile error on master. This
fixes the issue.
`VecFlat` has a casting operator to cast itself to the nested version of
the `Vec`. However, for a simple `Vec` type, the superclass of `VecFlat`
is the same type as the "nested" `Vec` type (which was flat to begin
with). This meant that the casting operator was never used because it
casted to the same type as the object being cast from. Most compilers
silently ignored this, but some gave a warning that the casting operator
would never be used because of this condition.
Fix the problem by having a different implemention of `VecFlat` when
applied to a `Vec` that is already flat.
Previously, the `MapFieldMergeAverage` and `MapFieldPermutation` helper
function had to iterate over every possible type and create a separate
code path. This change uses the new extract component functionality to
create separate code paths only for different component types. This both
requires less code (the common filter library dropped from 66MB to 42MB
on my Mac) and covers more cases (such as `Vec`s larger than 4
components).
To make the implementation easier, `UnknownArrayHandle` now can create a
new `UnknownArrayHandle` of the same `ValueType` but with the basic
storage (so you can work with read-only storage) and the ability to
allocate the unknown array.
This allows you to handle just about every type of array with about 10
basic types. It allows you to ignore both the size of `Vec`s and the
actual storage of the data.
The typical use case of `ArrayHandleStride` is to flexibly point into
another array, often looking at a single component in an array. It is
typical that multiple things will be accessing the same array, and bad
things could happen as they all try to resize. There was some code to
try to figure out what the size of the original array was, but it was
fragile.
It is safer for now to disable the behavior altogether. If a use case
pops up, we can reintroduce the code.
`ArrayExtractComponent` allows you to get a component of an array.
Unlike `ArrayHandleExtractComponent`, the type you get is always the
same: an `ArrayHandleStride`. This way, you can get an array that
contains the data of an extracted component with less templating and
potentially dramatically reduce the amount of code generated (although
some runtime integer arithmetic is added).
`vtkm::VecFlat` is a wrapper around a `Vec`-like class that may be a
nested series of vectors. For example, if you run a gradient operation
on a vector field, you are probably going to get a `Vec` of `Vec`s that
looks something like `vtkm::Vec<vtkm::Vec<vtkm::Float32, 3>, 3>`. That
is fine, but what if you want to treat the result simply as a `Vec` of
size 9?
The `VecFlat` wrapper class allows you to do this. Simply place the
nested `Vec` as an argument to `VecFlat` and it will behave as a flat
`Vec` class. (In fact, `VecFlat` is a subclass of `Vec`.) The `VecFlat`
class can be copied to and from the nested `Vec` it is wrapping.
There is a `vtkm::make_VecFlat` convenience function that takes an
object and returns a `vtkm::VecFlat` wrapped around it.

Many of the fancy `ArrayHandle`s are read-only and therefore connot
really create write portals. Likewise, many `ArrayHandle`s (both read-
only and read/write) have no way to resize themselves. In this case,
implementing the `CreateWritePortal` and `ResizeBuffers` methods in the
`Storage` class was troublesome. Mostly they just threw an exception,
but they also sometimes had to deal with cases where the behavior was
allowed.
To simplify code for developers, this introduces a pair of macros:
`VTKM_STORAGE_NO_RESIZE` and `VTKM_STORAGE_NO_WRITE_PORTAL`. These can
be declared in a `Storage` implementation when the storage has no viable
way to resize itself and create a write portal, respectively.
Having boilerplate code for these methods also helps work around
expected behavior for `ResizeBuffers`. `ResizeBuffers` should silently
work when resizing to the same size. Also `ResizeBuffers` should behave
well when resizing to 0 as that is what `ReleaseResources` does.
The `ReleaseResources` method should work for all arrays (even if it
effectively does not do anything). However, the implementation of
`ReleaseResources` is generally to call `Allocate` with 0. Several fancy
arrays balk at this because it is resizing a read-only array. There
should be an exception for this.
This class was used indirectly by the old `ArrayHandle`, through
`ArrayHandleTransfer`, to move data to and from a device. This
functionality has been replaced in the new `ArrayHandle`s through the
`Buffer` class (which can be compiled into libraries rather than make
every translation unit compile their own template).
This commit removes `ArrayManagerExecution` and all the implementations
that the device adapters were required to make. None of this code was in
any use anymore.
`ArrayTransfer` is used with the old `ArrayHandle` style to move data
between host and device. The new version of `ArrayHandle` does not use
`ArrayTransfer` at all because this functionality is wrapped in `Buffer`
(where it can exist in a precompiled library).
Once all the old `ArrayHandle` classes are gone, this class will be
removed completely. Although all the remaining `ArrayHandle` classes
provide their own versions of `ArrayTransfer`, they still need the
prototype to be defined to specialize. Thus, the guts of the default
`ArrayTransfer` are removed and replaced with a compile error if you try
to compile it.

I'm too lazy to look up the C++ spec, but it seems like template
parameter names would shadow the same names from a superclass.
Apparently that is not the case for Visual Studio. The `Storage` for the
cast array inherits from the `Storage` of the transform array. The
latter declares a private type named `SourceStorage`, and that is being
used instead of the former's `SourceStorage` template parameter. You
then get an error for accessing a private member that you did not want
in the first place.
Fix the problem by changing the name of the template parameter.
