This mechanism sets up CMake variables that allow a user to select which
modules/libraries to create. Dependencies will be tracked down to ensure
that all of a module's dependencies are also enabled.
The modules are also arranged into groups.
Groups allow you to set the enable flag for a group of modules at once.
Thus, if you have several modules that are likely to be used together,
you can create a group for them.
This can be handy in converting user-friendly CMake options (such as
`VTKm_ENABLE_RENDERING`) to the modules that enable that by pointing to
the appropriate group.
The `DynamicCellSet` class is now marked as deprecated (as is the header
that contains it), and all non-deprecated code is moved to its
`UnknownCellSet` replacement.
Also added a deprecation warning for the VariantArrayHandle.h header
file and deleted a couple inappropriate uses of it.
`UnknownCellSet` is an updated replacement for `DynamicCellSet`. The
next step in the replacement is to change `DataSet` to use the new
class.
Also replaced `DynamicCellSet` with `UnknownCellSet` in a few
places where `DynamicCellSet.h` was not directly included (and
therefore now no longer included at all). This change would have
to be made at some point anyway.
Previously, all methods in the `vtkm::cont::testing::Testing` class were
inlined in the header file. This makes sense for the methods that are
templated, but not so much for methods that are not templated.
Although this change provides minimal improvements with compile times
and object sizes (maybe). But the real benefit is that some of these
methods declare static objects. When declared in inlined functions, a
different object will be created for each translation unit. This can
lead to unexpected behavior when multiple versions of a supposed
singleton static object exist.
Some simulations trap floating point exceptions to ensure that their
code is working correctly, and we want VTK-m to work correctly in their
code. To check this, we want to turn on floating point exception
trapping in our test code. This is very implementation-specific, so for
now we are just turning it on for GCC. This will at least alert a
problem on some of the dashboards.
`VaraintArrayHandle` has been replaced by `UnknownArrayHandle` and
`UncertainArrayHandle`. Officially make it deprecated and point users to
the new implementations.
There was an error that caused deprecation warnings in VTK-m to be
suppressed, which meant that many uses of deprecated features went
unnoticed. This fixes those deprecation warnings.
The majority of the warnings were caused by the use of the deprecated
`Cast`, `CopyTo`, and `ResetTypes` methods of `UnknownArrayHandle` (or
`VariantArrayHandle`). Both `Cast` and `CopyTo` have been subsumed by
`AsArrayHandle` (to make the functionality more clear). `ResetTypes` now
requires a second template argument to define the storage types to try.
Also fixed some issues with `SerializableField` being deprecated.
This class is no longer necessary because `Field` can now be directly
serialized.
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.
The testing helper class provided a method named `GetTestDataBasePath`
that returned the base path to all the data files stored in the VTK-m
repo. This is fine, but it was a little cumbersome to build filenames.
To make things easier, there is now a new method named `DataPath` that
takes a string of the filename (or, rather, subpath) to the file in that
directory and automatically builds the path to it.
If a test throws any unexpected exception, the test is supposed to
detect that and fail. For the STL exceptions, the test failed to return
an error code. Fix that.
A new header named TypeList.h and the type lists have been redefined in
this new file. All the types have been renamed from `TypeListTag*` to
`TypeList*`. TypeListTag.h has been gutted to provide deprecated
versions of the old type list names.
There were also some other type lists that were changed from using the
old `ListTagBase` to the new `List`.
The previous implementation of `RuntimeDeviceTracker` occasionally
outputted a log at level `Info` about devices being enabled or disabled.
The problem was that the information given was inconsistent (so it would
sometimes announce one change but not announce a different corrective
change). This could cause weird confusions. For example, when you used a
`ColorTable`, it would use a `ScopedRuntimeDeviceTracker` to temporarily
force the device to `Serial`. The log will just tell you that the device
was forced to `Serial` but never tell you that the devices where
restored to include actual parallel devices.
This change helps correct these with the following changes:
* Added a new log level, `DevicesEnabled`, that is a higher level than
`Info`. All logging from `RuntimeDeviceTracker` goes to this log
level.
* Change the logging output of `RuntimeDeviceTracker` to output a list
of currently enabled devices whenever a change happens. That way you
don't have to guess what happend for each change.
* Change `ScopedRuntimeDeviceTracker` to log whenever the scope is
entered or left.
By removing the ability to have multiple CellSets in a DataSet
we can simplify the following things:
- Cell Fields now don't require a CellSet name when being constructed
- Filters don't need to manage what the active cellset is
The `From` and `To` nomenclature for topology mapping has been confusing for
both users and developers, especially at lower levels where the intention of
mapping attributes from one element to another is easily conflated with the
concept of mapping indices (which maps in the exact opposite direction).
These identifiers have been renamed to `VisitTopology` and `IncidentTopology`
to clarify the direction of the mapping. The order in which these template
parameters are specified for `WorkletMapTopology` have also been reversed,
since eventually there may be more than one `IncidentTopology`, and having
`IncidentTopology` at the end will allow us to replace it with a variadic
template parameter pack in the future.
Other implementation details supporting these worklets, include `Fetch` tags,
`Connectivity` classes, and methods on the various `CellSet` classes (such as
`PrepareForInput` have also reversed their template arguments. These will need
to be cautiously updated.
The convenience implementations of `WorkletMapTopology` have been renamed for
clarity as follows:
```
WorkletMapPointToCell --> WorkletVisitCellsWithPoints
WorkletMapCellToPoint --> WorkletVisitPointsWithCells
```
The `ControlSignature` tags have been renamed as follows:
```
FieldInTo --> FieldInVisit
FieldInFrom --> FieldInMap
FromCount --> IncidentElementCount
FromIndices --> IncidentElementIndices
```
