James Bardin	49439d02d1	sanitize provisioner output strings ... The grpc protocol requires strings to be valid utf8, but because provisioners often don't have control over the command output, invalid utf8 sequences can make it into the response causing grpc transport errors. Replace all invalid utf sequences with the standard utf replacement character in the provisioner output. The code is a direct copy from the go1.13 std library, and can be replaced with strings.ToValidUTF8 once it's available.	7 years ago
Martin Atkins	4fe9632f09	plugin: Establish our current plugin protocol as version 5 ... The main significant change here is that the package name for the proto definition is "tfplugin5", which is important because this name is part of the wire protocol for references to types defined in our package. Along with that, we also move the generated package into "internal" to make it explicit that importing the generated Go package from elsewhere is not the right approach for externally-implemented SDKs, which should instead vendor the proto definition they are using and generate their own stubs to ensure that the wire protocol is the only hard dependency between Terraform Core and plugins. After this is merged, any provider binaries built against our helper/schema package will need to be rebuilt so that they use the new "tfplugin5" package name instead of "proto". In a future commit we will include more elaborate and organized documentation on how an external codebase might make use of our RPC interface definition to implement an SDK, but the primary concern here is to ensure we have the right wire package name before release.	8 years ago

The new helper/plugin package contains the grpc servers for handling the new plugin protocol The GRPCProviderServer and GRPCProvisionerServer handle the grpc plugin protocol, and convert the requests to the legacy schema.Provider and schema.Provisioner methods.	8 years ago
