Martin Atkins	6b4ed241d3	docs: Provider protocol wire format for values ... 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.	6 years ago
Paddy	e6592dc710	Add support for provider metadata to modules. (#22583) ... 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.

Martin Atkins	e1af10b554	docs: README for the plugin-protocol directory ... 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.	7 years ago
James Bardin	fa1f9be539	add tfplugin proto docs files ... 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.	7 years ago
