Update the full-replacement example graph to show the transitive
dependency that is required for the destroy-then-update case. Add
another example describing the case where we reduce the graph to
only an update and replace and the dependency on the destroy node
remains.
* checkpoint save: update InternalValidate tests to compare exact error
* configschema: extract and extend attribute validation
This commit adds an attribute-specific InternalValidate which was extracted directly from the block.InternalValidate logic and extended to verify any NestedTypes inside an Attribute. Only one error message changed, since it is now valid to have a cty.NilType for Attribute.Type as long as NestedType is set.
* terraform: validate provider schema's during NewContext
We haven't been able to guarantee that providers are validating their own schemas using (some version of) InternalValidate since providers were split out of the main codebase. This PR adds a call to InternalValidate when provider schemas are initially loaded by NewContext, which required a few other changes:
InternalValidate's handling of errors vs multierrors was a little weird - before this PR, it was occasionally returning a non-nil error which only stated "0 errors occurred" - so I addressed that in InternalValidate. I then tested this with a configuration that was using all of our most popular providers, and found that at least on provider had some invalid attribute names, so I commented that particular validation out. Adding that in would be a breaking change which we would have to coordinate with enablement and providers and (especially in this case) make sure it's well communicated to external provider developers.
I ran a few very unscientific tests comparing the timing with and without this validation, and it appeared to only cause a sub-second increase.
* refactor validate error message to closer match the sdk's message
* better error message
* tweak error message: move the instruction to run init to the end of the message, after the specific error.
Support for attributes with NestedTypes was added in https://github.com/hashicorp/terraform/pull/28055, and should have included a format version bump: this is a backwards-compatible change, but consumers will need to be updated in order to properly decode attributes (with NestedTypes) going forward.
We currently count on interconnecting destroy nodes to handle the
create->destroy dependency edge for replacement, but when the create
node is only an update we don't connect that edge directly.
Lookup all creators that are dependencies of the destory node and ensure
they are connected.
Unfortunately at the moment I'm adding this the release isn't yet
available in the current version of goenv, but due to these including
security stuff and because we're about to make a Terraform release we're
letting this get slightly ahead of goenv on the assumption that it will
catch up shortly.
The traversal value is normally a valid HCL string, but can be
simplified if a traversal step has a complex index value (e.g. an
object). This means it is not always parseable HCL, so this commit
updates the documentation to clarify this and explicitly record that we
do not guarantee its contents are stable. The purpose of these values is
purely for building human-readable UI.
These aim to allow hinting to Terraform about situations where it's not
able to automatically infer value sensitivity.
"nonsensitive" is for situations where Terraform's behavior is too
conservative, such as when a new value is derived from a sensitive value
in such a way that all of the sensitive content is removed.
"sensitive", on the other hand, is for situations where Terraform can't
otherwise infer that a value is sensitive. These situations should be
pretty rare in a module that's making effective use of sensitive input
variables and output values, but the documentation shows one example of
an uncommon situation where a more direct hint via this function would
be needed.
Both of these functions are aimed at only occasional use in unusual
situations. They are here for reasons of pragmatism, not because we
expect them to be used routinely or recommend their use.
This is not currently a supported interface, but we plan to release
tool(s) that consume parts of it that are more dependable later,
separately from Terraform CLI itself.
In line with the other complex JSON output formats for plan and provider
schema, here we add an explicit `format_version` field to the JSON
output of terraform validate.
etcdv3 acceptance tests fail due to attempting to pass slices of strings
for the endpoints config to HCL2ValueFromConfigValue() which does not
handle that type.
Not a pretty solution but a helper function that converts the endpoints to a slice of
empty interfaces satisfies the requirements of the
HCL2ValueFromConfigValue function.

When migrating state to a new workspace, the version check would error
due to a 404 error on fetching the workspace record. This would result
in failed state migration.
Instead we should look specifically for a 404 error, and allow migration
to continue. If we're just about to create the workspace, there can't be
a version incompatibility problem.
* format/diff: extract attributes-writing logic to a function
This is a stepping-stone commit (for easier reviewability, and to prove that tests did not change) as part of writing a NestedType-specific diff printer.
* command/format: add support for formatting attributes with NestedTypes
This commit adds custom formatting for NestedType attributes. THe logic was mostly copied from the block diff printer, with minor tweaks here and there. I used the (excellent) existing test coverage and added a NestedType attribute to every test.
Since the (nested-block specific) test schemas were nearly identical, I added a function that returns the schema with the requested NestingMode.
If no default is specified for a nested optional structural typed
attribute, the defaults function should just pass through its input.
Before this commit the function assumed that the fallback value was
always of the correct type, which would panic.
