All resources use EvalWriteState to store their state, so we need a way
to switch the states when the resource is refreshing vs when it is
planning. (this will likely change once we factor out the EvalNode pattern)
Since plan uses the state as a scratch space for evaluation, we need an
entirely separate state to store the refreshed resources values during
planning. Add a RefreshState method to the EvalContext to retrieve a
state used only for refreshing resources.
While we like codecov, and the coverage goals, we've frequently ignored
the failures for various reasons. These have confused community members
submitting PRs and it can be confusing to look at a list of merged PRs
with the big X indicating failed checks ("confusing" isn't really a
problem, but if there were actually a bad merge, it could be hard to
find which in a list of commits actually had an important failure).
Fixes a mild inconvenience.
Test that the changes which use the sensitive variable have
corresponding path value marks. Also remove the unrelated validate
function from this test.
* remove leftover debug line
* terraform: refactor ProviderEvalTree
This PR refactors the ProviderEvalTree by folding the entire tree into
straight-through code in NodeApplyableProvider Execute (formally
EvalTree). The EvalConfigProvider functions were refactored into
NodeApplyableProvider functions (since that was the only place they were
used).
I also removed the unused node_provider_disabled code.
* revert removal of graphNodeCloseProvider EvalTree, replace with Execute
* terraform: remove unused eval node
* add UpdateStateHook function to replace EvalUpdateStateHook
* early exit error isn't
* terraform: NodeDestroyResourceInstance refactor
This PR refactor's NodeDestroyResourceInstance EvalTree() into an
Execute() node. EvalRequireState and evalWriteEmptyState were used only
by this node, and they have been removed in favor of straight code.
There are still many calls to someEvalNode.Eval() in NodeDestroyResourceInstance: I plan on refactoring the remaining EvalTree()s before tacking those Eval()s (all of which are used by many graph nodes)
I've added a new function, UpdateStateHook, that is effectively the same
as EvalUpdateStateHook. The latter will be removed when the larger
EvalNode refactor project is complete.
EvalModuleCallArguments is now a method on nodeModuleVariable, it's only
caller, and the other functions have been replaces with straight through
code (or in the case of evalVariableValidations, a standalone function).
I was unable to add tests for nodeModuleVariable.Execute, which requires
fixtures that aren't part of the MockEvalContext (a scope.evalContext is
one); it's not ideal but that function should be well covered by the
context tests so I chose to leave it as-is.
Finally, I removed the unused function hclTypeName. Deleting code is
fun!
While this was easier to spot during plan, it is also possible to
evaluate resources with 0 instances during apply as well.
This doesn't effect the failure when scaling CBD instances, it only
changes the fact that the inconsistent value is no longer unknown.
Remove the check for CreateBeforeDestroyOverride which can't happen in a
destroy node.
Remove the unnecessary GraphNodeAttachDestroyer interface, since we
don't use it now that plans can record the create+destroy order.
For a credentials helper plugin to be useful with Terraform 0.13+, we
need to cope with the case of having no credentials for a host without
this being an error. This is to allow the public Terraform Registry to
be accessed without supplying a token.
The way to implement this is to respond to queries for credentials for a
host which has no credentials stored with an empty object and a success
exit code. This contradicts the previous documentation, which calls for
an error response in this case.
EvalTrees
The import EvalTree()s have been replaced with Execute +
straight-through code, which let me remove eval_import_state.go.
graphNodeImportStateSub's Execute() function is still using the
old-style (not-refactored) calls to EvalRefresh and EvalWriteState;
those are being saved for a later refactor once all (or at least most)
of the EvalTree()s are gone.
I've added incredibly basic tests for both Execute() functions; they are
only enough to verify basics - the real testing happens in
context_import_test.go.
Use a slightly modified value renderer from terraform-provider-testing
to display values in the console REPL, as well as outputs from the apply
and outputs subcommands.

Note that this is technically a breaking change for the console
subcommand, which would previously error if the user attempted to render
an unknown value (such as an unset variable). This was marked as an
unintentional side effect, with the goal being the new behaviour of
rendering "(unknown)", which is why I changed the behaviour in this
commit.
* terraform: refactor signature of EvalContext.InitProvisioner
Nothing was using the returned provisioners.Interface, so I simplified
the signature.
* terraform: remove provisioner-related EvalTree()s
The various Evals in eval_provisioner were removed from all callers and
replaced with straight-through code.
`NodeValidatableResource.EvalTree()` to `Execute()` was more involved. I
chose to leave the `EvalValidateResource` and `EvalValidateProvisioner`
Eval functions mostly as-is, changing the main function to `.Validate` to
make it clear that these are no longer eval nodes. Eventually I expect
to rename the file (perhaps to just Validate).
