A few tests were inadvertently renamed, causing them to be be skipped.
For some reason this is not caught by the `vet` pass that happens during
normal testing.
The variable nodes are not only used during plan and apply, so remove
those from there names. The "plan" node is now
`nodeExpandModuleVariable` and the "apply" node is now just
`nodeModuleVariable`.
Remove unnecessary methods, as the nodeModuleVariable is no longer used
in the full graph transformations.
Previously we were using the experimental HCL 2 repository, but now we'll
shift over to the v2 import path within the main HCL repository as part of
actually releasing HCL 2.0 as stable.
This is a mechanical search/replace to the new import paths. It also
switches to the v2.0.0 release of HCL, which includes some new code that
Terraform didn't previously have but should not change any behavior that
matters for Terraform's purposes.
For the moment the experimental HCL2 repository is still an indirect
dependency via terraform-config-inspect, so it remains in our go.sum and
vendor directories for the moment. Because terraform-config-inspect uses
a much smaller subset of the HCL2 functionality, this does still manage
to prune the vendor directory a little. A subsequent release of
terraform-config-inspect should allow us to completely remove that old
repository in a future commit.
Although this rarely matters, making it always be nil when empty makes
deep assertions simpler in tests.
This also includes a minor update to the test in the core package that
first encountered this problem, to improve the quality of its output
on failure.
After the refactoring to integrate HCL2 many of the tests were no longer
using correct types, attribute names, etc.
This is a bulk update of all of the tests to make them compile again, with
minimal changes otherwise. Although the tests now compile, many of them
do not yet pass. The tests will be gradually repaired in subsequent
commits, as we continue to complete the refactoring and retrofit work.
