function: Replace usage of diagnostics with function errors during execution of provider-defined functions #925

Reference: https://github.com/hashicorp/terraform-providers-devex-internal/issues/175

This PR contains changes for replacing the returning of diagnostics with function errors during the execution of the CallFunction RPC and the associated Run method defined within provider-defined functions.

A new error type, function.FuncError has been introduced.

This will require that provider developers alter the implementation of any previously implemented provider-defined functions as the response type that is returned by the Run method has been altered.

Currently, the structure of the RunResponse type is:

type RunResponse struct {
	Diagnostics diag.Diagnostics
	Result ResultData
}

The changes contained within this PR have restructured the RunResponse in the following way:

type RunResponse struct {
	Errors *function.FuncError
	Result ResultData
}

This will require that provider-defined function implementations that currently interact with diagnostics will need to be altered to interact with a function error.

func (f *ExampleFunction) Run(ctx context.Context, req function.RunRequest, resp *function.RunResponse) {
    var boolArg bool
    var stringArg string

    resp.Error = function.ConcatFuncErrors(resp.Error, req.Arguments.Get(ctx, &boolArg, &stringArg))
 
    // ... other logic ...
}

Context

The motivation behind the changes in this PR arise from a desire to keep the data that flows between Terraform core and providers during the CallFunction RPC aligned with the native cty interface that is used by Terraform core. There is an associated PR on Terraform core for making equivalent changes on the core side of the protocol.

Given how bespoke these will be compared to other provider development functionality, it may be good to consider:

  • Consolidating this into the existing function package as it just happens to be a very awkward situation these error types are being introduced, so (famous last words) other error types would not be created in preference of diagnostics, or if they were, they would hopefully be unrelated to functions.
  • Whether FunctionError (function.Error if above happens) should be simplified to a struct type instead of an interface. I'm not sure whether we want the extensibility/complexity that is offered by the diag package here. It might be interesting to peek in source available provider code whether developers are leveraging the extensibility of diagnostics via those interface(s) or just implementing the existing types/methods. Implementing Go 1.13+ error wrapping capabilities might be good enough, where diagnostics do have separate capabilities beyond pure error handling. 😄

I've gone ahead and refactored fwerror.FunctionErrors to function.FuncError.

These changes have removed the fwerror.FunctionError, and fwerror.FunctionErrorWithFunctionArgument interfaces, as well as removing the fwerror.FunctionErrors type. In their place is a single function.FuncError struct type.

A function.ConcatFuncErrors helper function has been created which concatenates the function.FuncError text fields of two or more instances of function.FuncError. We could, if we decide to go this route, make the concatenation a method of FuncError itself. I thought concatenation might represent the simplest implementation that would allow handling of multiple instances of function.FuncError, given that errors.Join returns the error interface, requiring that we either alter the return type from function.FuncError to error and use type assertion where necessary, or implement our own version of Join, specifically for function.FuncError. In the latter case, unless we re-introduce an interface, I believe we'll need to add a errs []*FuncError field to function.FuncError struct type, which seems a little odd to me.

Interested to hear your thoughts on the function.FuncError implementation, and the associated helper functions.

The usages of github.com/hashicorp/terraform-plugin-framework/diag that I found all appeared to be using the pre-defined diagnostics rather than new implementations of the available interfaces:

Would it be safer for the framework to expose this abstraction more inline with the protocol (e.g. a single function error) and then potentially offer opinionated helper(s) that may change over time for joining multiple errors into one? Is errors.Join() or our own version of that acceptable enough? We have tried to avoid the framework from forcing opinionated behaviors on provider developer responses where possible in the past.

As mentioned above, we now have a single function.FuncError struct type, with function.ConcatFuncErrors and function.FuncErrorFromDiags helper functions. The function.ConcatFuncErrors is our current version of errors.Join().

## How Errors Affect State

**Returning function errors does not stop the state from being updated**.
Terraform will still persist the returned state even when function errors
are returned with it. This is to allow Terraform to persist the values that have
already been modified when a resource modification requires multiple API
requests or an API request fails after an earlier one succeeded.

When returning function errors, we recommend resetting the state in the
response to the prior state available in the configuration.

Can we double check this? I believe that typically function calls and their errors happen will so early in the operation graph that this would not necessarily be true (except maybe if there are unknown values being passed as arguments).

I'm wondering if its better to just omit this whole section, since "state" is not a function concept and this was mostly relating to managed resources, or whether we need to get into those function error handling implementation details.

If it's ok, I'm going to hold off making any further changes to the documentation until we converge on the implementation of FunctionError/FuncError. But as an aside, I checked this, and you're quite right, returning a diagnostic will result in no alteration to the state file. Returning a function error currently has no effect, presumably because it is not yet being handled within core, and requires hashicorp/terraform#34603 to be merged. Although, I believe I could build Terraform with that branch and test.

Running go get github.com/hashicorp/terraform-plugin-go results in the addition of the following entry to go.mod:

toolchain go1.21.6

Which would result in an analogous CI failure to that seen on terraform-plugin-mux

Given that our CI runs both Go 1.20 and 1.21, I removed this directive, but perhaps this should be handled differently?

Oh interesting. It sounds like what you've done is basically the solution: https://go.dev/doc/toolchain

The same requirement applies in reverse when downgrading: if the go.mod starts at go 1.22.1 and toolchain go1.24rc1, then go get toolchain@go1.22.9 will update only the toolchain line, but go get toolchain@go1.21.3 will downgrade the go line to go 1.21.3 as well. The effect will be to leave just go 1.21.3 with no toolchain line.

The special form toolchain@none means to remove any toolchain line, as in go get toolchain@none or go get go@1.25.0 toolchain@none.

Sounds like we could also potentially just run a go get toolchain@none before we run our CI, but you've essentially done that..... Will a go mod tidy bring it back?

Comment placement not really relevant, but I wanted a thread 😆

Open question: Do we think it'd be valuable to note in the diag package doc that this package does not contain function specific error handling? Currently it's kind of generic about the error handling it can do:

// Package diag implements diagnostic functionality, which is a practitioner
// feedback mechanism for providers. It is designed for display in Terraform
// user interfaces, rather than logging based feedback, which is generally
// saved to a file for later inspection and troubleshooting.
package diag

Maybe we could redirect them to the function package / specific error struct (since this is the only exception currently)

Same question for the package doc for function, should we note that it also contains error handling specific to function implementations:

// Package function contains all interfaces, request types, and response
// types for a Terraform Provider function implementation.
//
// In Terraform, a function is a concept which enables provider developers
// to offer practitioners a pure function call in their configuration. Functions
// are defined by a function name, such as "parse_xyz", a definition
// representing the ordered list of parameters with associated data types and
// a result data type, and the function logic.
//
// The main starting point for implementations in this package is the
// [Function] type which represents an instance of a function that has its own
// argument data when called. The [Function] implementations are referenced by a
// [provider.Provider] type Functions method, which enables the function for
// practitioner and testing usage.

I'm happy to go with consensus on this one. Right now FuncErrorFromDiags is formatting as follows:

NewFuncError(fmt.Sprintf("%s: %s", d.Summary(), d.Detail()))

So, I'll leave the formatting as it is for right now, but if we decide to update to use \n\n between the "summary" and "detail" I'll update it in all locations.

We might want to describe the behavior of warning diagnostics here (that they will log and not be represented in the resulting function error)

Also I'm not sure where else we need it, but it might be good to mention some of the automatic "downgrading" of diagnostics somewhere (in-case developers have existing custom types for a parameter that return warning diags, for example)

* resource/schema: Ensure invalid attribute default value errors are raised (#933)

Reference: #590
Reference: #930

Previously the logic handling attribute `Default` values would silently ignore any type errors, which would lead to confusing planning data behaviors. This updates the logic to raise those error properly and adds covering unit testing.

These error messages are using the underlying `tftypes` type system errors which is currently a pragmatic compromise throughout various parts of the framework logic that bridges between both type systems to save additional type assertion logic and potential bugs relating to those conversions. In the future if the internal `tftypes` handling and exported fields are replaced with the framework type system types, this logic would instead return error messaging based on the framework type system errors.

This also will enhance the schema validation logic to check any `Default` response value and compare its type to the schema, which will raise framework type system errors during the `GetProviderSchema` RPC, or during schema unit testing if provider developers have implemented that additional testing.

* Update provider functions testing docs to help users avoid nil pointer error (#940)

* Fix capitalisation

* Update example test to mitigate nil pointer error

In the future if the internal `tftypes` handling and exported fields are replaced with the framework type system types, this logic would instead return error messaging based on the framework type system errors.

This also will enhance the schema validation logic to check any `Default` response value and compare its type to the schema, which will raise framework type system errors during the `GetProviderSchema` RPC, or during schema unit testing if provider developers have implemented that additional testing.

    resource/schema: Ensure invalid attribute default value errors are raised (#933)

    Reference: #590
    Reference: #930

    Previously the logic handling attribute `Default` values would silently ignore any type errors, which would lead to confusing planning data behaviors. This updates the logic to raise those error properly and adds covering unit testing.

    These error messages are using the underlying `tftypes` type system errors which is currently a pragmatic compromise throughout various parts of the framework logic that bridges between both type systems to save additional type assertion logic and potential bugs relating to those conversions. In the future if the internal `tftypes` handling and exported fields are replaced with the framework type system types, this logic would instead return error messaging based on the framework type system errors.

    This also will enhance the schema validation logic to check any `Default` response value and compare its type to the schema, which will raise framework type system errors during the `GetProviderSchema` RPC, or during schema unit testing if provider developers have implemented that additional testing.
