This is actually a description of the "cty" library's encoding of refined
values, but from the perspective of the plugin protocol it's an
implementation detail that Terraform Core outsources that to a third-party
library, and current server-side implementations of the protocol use an
independent implementation of this format which will need to be compatible
with what cty does.
This opts to inline document these intentional design decisions in the protocol definition as a catch-all for it not being documented elsewhere.
Protocol Buffers files updated via:
```shell
make protobuf
```
Reference: https://github.com/hashicorp/terraform/issues/30373
This change forward ports the `legacy_type_system` boolean fields in the `ApplyResourceChange.Response` and `PlanResourceChange.Response` messages that existed in protocol version 5, so that existing terraform-plugin-sdk/v2 providers can be muxed with protocol version 6 providers (e.g. terraform-plugin-framework) while also taking advantage of the newer protocol features. This functionality should not be used by any providers or SDKs except those built with terraform-plugin-sdk.
Updated via:
```shell
cp docs/plugin-protocol/tfplugin6.1.proto docs/plugin-protocol/tfplugin6.2.proto
# Copy legacy_type_system fields from tfplugin5.2.proto into ApplyResourceChange.Response and PlanResourceChange
rm internal/tfplugin6/tfplugin6.proto
ln -s ../../docs/plugin-protocol/tfplugin6.2.proto internal/tfplugin6/tfplugin6.proto
go run tools/protobuf-compile/protobuf-compile.go `pwd`
# Updates to internal/plugin6/grpc_provider.go
```
Minor version increase to deprecate min_items and max_items in nested
types.
Nested types have MinItems and MaxItems fields that were inherited from
the block implementation, but were never validated by Terraform, and are
not supported by the HCL decoder validations. Mark these fields as
deprecated, indicating that the SDK should handle the required
validation.
Releasing a new major protocol version requires coordination between a
few different projects and codebases, and it's easy to forget a step.
This commit introduces a doc to keep track of these steps, making it
less likely one will be omitted or forgotten.
* providers.Interface: rename ValidateDataSourceConfig to
ValidateDataResourceConfig
This PR came about after renaming ValidateResourceTypeConfig to
ValidateResourceConfig: I now understand that we'd called it the former
instead of the latter to indicate that the function wasn't necessarily
operating on a resource that actually exists. A possibly-more-accurate
renaming of both functions might then be ValidateManagedResourceConfig
and ValidateDataResourceConfig.
The next commit will update the protocol (v6 only) as well; these are in
separate commits for reviewers and will get squashed together before
merging.
* extend renaming to protov6
This is the first commit for plugin protocol v6. This is currently
unused (dead) code; future commits will add the necessary conversion
packages, extend configschema, and modify the providers.Interface.
The new plugin protocol includes the following changes:
- A new field has been added to Attribute: NestedType. This will be the
key new feature in plugin protocol v6
- Several massages were renamed for consistency with the verb-noun
pattern seen in _most_ messages.
- The prepared_config has been removed from PrepareProviderConfig
(renamed ValidateProviderConfig), as it has never been used.
- The provisioner service has been removed entirely. This has no impact
on built-in provisioners. 3rd party provisioners are not supported by
the SDK and are not included in this protocol at all.
Although we have in this same directory the protocol buffers schemas for
the static parts of the provider wire protocol, many of the protocol
messages include DynamicValue messages that are presented in a nested
dynamic serialization format.
That format was previously not documented, and was thus defined only by
the implementation. Terraform happens to use a third-party library to
implement parts of this encoding, which means that the rules were even
harder to track down from reading the code.
Regardless of how Terraform happens to implement its serialization and
deserialization of DynamicValue, it's the wire format that is contractual
and so this document is an implementation-agnostic description of the
mapping rules for serializing any Terraform Language value by reference to
a provider-defined schema.
All future changes to the rules described in here must be backward
compatible until protocol major version 6, which is not currently planned.
Implement a new provider_meta block in the terraform block of modules, allowing provider-keyed metadata to be communicated from HCL to provider binaries.
Bundled in this change for minimal protocol version bumping is the addition of markdown support for attribute descriptions and the ability to indicate when an attribute is deprecated, so this information can be shown in the schema dump.

This is an initial partial description of the plugin protocol focused
mainly on explaining the purpose of the .proto files. In subsequent
updates we will also document the negotiation protocol, etc.
For this first pass the goal was just to publish some information that was
already available in an internal design document so that it's visible to
SDK implementers. It is focused on the .proto versioning strategy because
that was the main topic of the internal design documentation this was
based on.
Add versioned tfplugin proto files to the docs directory, for easier
reference. The latest version starts as a symlink to the current
file used for generated the tfplugin package in ./internal/tfplugin5.
When changing the protocol version, the old file must be copied to
./docs/plugin-protocol/, and a new symlink created for the latest
version.
