We only persist a new state if the actual state contents have
changed. This test demonstrates that behavior by calling write
and persist methods when either the lineage or serial have changed.
The only situation where `state mv` needs to understand the each mode is
when with resource addresses that may reference a single instance, or a
group of for_each or count instances. In this case we can differentiate
the two by checking the existence of the NoKey instance key.
Due to the fact that resources can transition between each modes, trying
to track the mode for a resource as a whole in state doesn't work,
because there may be instances with a mode different from the resource
as a whole. This is difficult for core to track, as this metadata being
changed as a side effect from multiple places often causes core to see
the incorrect mode when evaluating instances.
Since core can always determine the correct mode to evaluate from the
configuration, we don't need to interrogate the state to know the mode.
Once core no longer needs to reference EachMode from states, the
resource state can simply be a container for instances, and doesn't need
to try and track the "current" mode.
* Include eval in output walk
This allows outputs to be evaluated in the evalwalk,
impacting terraform console. Outputs are still not evaluated
for terraform console in the root module, so this has
no impact on writing to state (as child module outputs are not
written to state). Also adds test coverage to the console command,
including for evaluating locals (another use of the evalwalk)
Previously, resources without explicit provider configuration (i.e. a
`provider =` attribute) would be assigned a default provider based upon
the resource type. For example, a resource `foo_bar` would be assigned
provider `hashicorp/foo`.
This behaviour did not work well with community or partner providers,
with sources configured in `terraform.required_providers` blocks. With
the following configuration:
terraform {
required_providers {
foo = {
source = "acme/foo"
}
}
}
resource foo_bar "a" { }
the resource would be configured with the `hashicorp/foo` provider.
This commit fixes this implied provider behaviour. First we look for a
provider with local name matching the resource type in the module's
required providers map. If one is found, this provider is assigned to
the resource. Otherwise, we still fall back to a default provider.
Add the expansion transformer to the eval graph,
which is used in rare scenarios which includes running
terraform console. Prevents panic when running terraform
console in contexts with module expansion
We now permit at most one `required_providers` block per module (except
for overrides). This prevents users (and Terraform) from struggling to
understand how to merge multiple `required_providers` configurations,
with `version` and `source` attributes split across multiple blocks.
Because only one `required_providers` block is permitted, there is no
need to concatenate version constraints and resolve them. This allows us
to simplify the structs used to represent provider requirements,
aligning more closely with other structs in this package.
This commit also fixes a semantic use-before-initialize bug, where
resources defined before a `required_providers` block would be unable to
use its source attribute. We achieve this by processing the module's
`required_providers` configuration (and overrides) before resources.
Overrides for `required_providers` work as before, replacing the entire
block per provider.
* update github.com/aws/aws-sdk-go to v1.30.9

```
NOTES:
* backend/s3: Region validation now automatically supports the new `af-south-1` (Africa (Cape Town)) region. For AWS operations to work in the new region, the region must be explicitly enabled as outlined in the [AWS Documentation](https://docs.aws.amazon.com/general/latest/gr/rande-manage.html#rande-manage-enable). When the region is not enabled, the Terraform S3 Backend will return errors during credential validation (e.g. `error validating provider credentials: error calling sts:GetCallerIdentity: InvalidClientTokenId: The security token included in the request is invalid`).

* backend/s3: Support automatic region validation for `af-south-1`

Since objects and tuples have fixed numbers of elements, we can't return
an unknown version of those during validation. While we could return a
DyanmicVal (which was used previously), that prevents the validation of
outputs and attributes in config references.
Instead, we can return a synthetic type made from a List or Map based
on the configuration, which will allow us to more precisely validate
indexes, attributes, and outputs.
Because tuple types have a fixed number of elements, and we may not know
the number of expanded instances, we can't use an unknown tuple type to
validate index expressions.
Since evaluation is driven only by the configuration (i.e. you can't
interpolate what's not in the config), the resource evaluation should
also follow configuration rather than state. Determining the each mode
solely from the config, and applying that to the state and changes
removes the need for EachMode in the resource state. This bypasses the
awkward dance around getting the correct EachMode set in and retrieved
from state during plan when it changes in the config.
* internal/getproviders: apply case normalizations in ParseMultiSourceMatchingPatterns
This is a very minor refactor which takes advantage of addrs.ParseProviderPart case normalization to normalize non-wildcard sources.
These were being used in an earlier iteration of the provider installation
configuration but it was all collapsed down into a single
ProviderInstallationMethod type later, making these redundant.
This is an initial draft of documentation for this new feature of the
CLI configuration. This is mainly intended as a placeholder for now,
because there are other documentation updates pending for the new provider
namespacing and installation scheme and we'll likely want to revise these
docs to better complement the broader documentation once it's written.
This exercises the ability to customize the installation methods used by
the provider plugin installer, in this case forcing the use of a custom
local directory with a result essentially the same as what happens when
you pass -plugin-dir to "terraform init".
The CLI config can be written in both native HCL and HCL JSON syntaxes, so
the provider_installation block must be expressible using JSON too. Our
previous checks to approximate HCL 2-level strictness were too strict for
HCL JSON where things are more ambiguous even in HCL 2, so this includes
some additional relaxations if we detect that we're decoding an AST
produced from a JSON file.
This is still subject to the quirky ways HCL 1 handles JSON though, so
the JSON value must be structured in a way that doesn't trigger HCL's
heuristics that try to guess what is a block and what is an attribute.
(This is the issue that HCL 2 fixes by always decoding using a schema;
there's more context on this in:
https://log.martinatkins.me/2019/04/25/hcl-json/ )
