CHANGELOG.md

1.2.0 (March 21, 2023)

NOTES:

• New DEBUG level Detected value change between proposed new state and prior state log messages with the offending attribute path are now emitted when proposed new state value differences would cause the framework to automatically mark all unconfigured Computed attributes as unknown during planning. These can be used to troubleshoot potential resource implementation issues, or framework and Terraform plan logic bugs. (#630)
• This Go module has been updated to Go 1.19 per the Go support policy. Any consumers building on earlier Go versions may experience errors. (#682)

FEATURES:

• resource/schema: Introduce packages, interface types, and built-in static value functionality for schema-based default values (#674)

ENHANCEMENTS:

• internal/fwserver: Added DEBUG logging to aid troubleshooting unexpected plans with unknown values (#630)
• types/basetypes: Add BoolValue type NewBoolPointerValue() creation function and ValueBoolPointer() method (#689)
• types/basetypes: Add Float64Value type NewFloat64PointerValue() creation function and ValueFloat64Pointer() method (#689)
• types/basetypes: Add Int64Value type NewInt64PointerValue() creation function and ValueInt64Pointer() method (#689)
• types/basetypes: Add StringValue type NewStringPointerValue() creation function and ValueStringPointer() method (#689)
• resource/schema: Added Default fields to Attribute types, which support schema-based default values (#674)

BUG FIXES:

• types/basetypes: Fixed Float64Type type ValueFromTerraform method to handle valid, stringified numbers from Terraform (#648)
• resource: Prevented nested attribute and block plan modifications from being undone (#669)

1.1.1 (January 13, 2022)

BUG FIXES:

• all: Prevented tftypes.NewValue can't use []tftypes.Value as a tftypes.Object panics with schemas that included SingleNestedBlock (#624)

1.1.0 (January 13, 2022)

NOTES:

• all: For data handling consistency with attributes, unconfigured list and set blocks will now be represented as a null list or set instead of a known list or set with zero elements. This prevents confusing situations with validation and plan modification, where it was previously required to check block values for the number of elements. Logic that was previously missing null value checks for blocks may require updates. (#604)
• tfsdk: The Config, Plan, and State type PathMatches() method logic previously returned Invalid Path Expression for Schema Data errors based on implementation details of the underlying data, which prevented returning zero matches in cases where the expression is valid for the schema, but there was no actual data at the path. Providers can now determine whether zero matches is consequential for their use case. (#602)

ENHANCEMENTS:

• path: Added Expressions type Matches method for checking if any expression in the collection matches a given path (#604)
• tfsdk: Automatically prevented Terraform nested blocks must be empty to indicate no blocks errors for responses containing Plan and State types (#621)

BUG FIXES:

• datasource/schema: Prevented ListNestedBlock and SetNestedBlock type DeprecationMessage field from causing Block Deprecated warnings with unconfigured blocks (#604)
• datasource: Prevented ConfigValidators from unexpectedly modifying or removing prior validator diagnostics (#619)

• resource: Prevented ConfigValidators from unexpectedly modifying or removing prior validator diagnostics (#619)
• tfsdk: Fixed false positive Invalid Path Expression for Schema Data error to be schema-determined instead of data-determined (#602)
• types/basetypes: Fixed ObjectType type ApplyTerraform5AttributePathStep method to return an error instead of nil for invalid attribute name steps (#602)

1.0.1 (December 19, 2022)

BUG FIXES:

• resource/schema/planmodifier: Prevented assignment to entry in nil map panic for Object type plan modifiers (#591)
• types/basetypes: Prevented type mutation via the ObjectType type AttributeTypes() method return (#591)

• tfsdk: The NewProtocol6Server() function has been deprecated in preference of providerserver.NewProtocol6() and providerserver.NewProtocol6WithError() functions, which will simplify muxing and testing implementations. The tfsdk.NewProtocol6Server() function will be removed in the next minor version. (#308)
• tfsdk: The ResourceImportStateNotImplemented() function has been deprecated. Instead, the ImportState method can be removed from the Resource and the framework will automatically return an error diagnostic if import is attempted. (#297)
• tfsdk: The Resource interface no longer requires the ImportState method. A separate ResourceWithImportState interface now defines the same ImportState method. (#297)
• tfsdk: The Serve() function has been deprecated in preference of the providerserver.Serve() function. The tfsdk.Serve() function will be removed in the next minor version. (#308)
• tfsdk: The ServeOpts type has been deprecated in preference of the providerserver.ServeOpts type. When migrating, the Name field has been replaced with Address. The tfsdk.ServeOpts type will be removed in the next minor version. (#308)
• tfsdk: The previously unexported server type has been temporarily exported to aid in the migration to the new providerserver package. It is not intended for provider developer usage and will be moved into an internal package in the next minor version. (#308)

FEATURES:

• Introduced providerserver package, which contains all functions and types necessary for serving a provider in production or acceptance testing. (#308)
• tfsdk: Added optional ResourceWithUpgradeState interface, which allows for provider defined logic when the UpgradeResourceState RPC is called (#292)

ENHANCEMENTS:

• tfsdk: Added DEBUG level logging for all framework handoffs to provider defined logic (#300)
• tfsdk: Added ResourceWithImportState interface, which allows Resource implementations to optionally define the ImportState method. (#297)
• tfsdk: Added automatic (DeleteResourceResponse.State).RemoveResource() call after Resource type Delete method execution if there are no errors (#301)

0.6.1 (March 29, 2022)

BUG FIXES:

• types: Prevented panics with missing type information during Float64, Int64, and Set validation logic (#259)

0.6.0 (March 10, 2022)

NOTES:

• The underlying terraform-plugin-log dependency has been updated to v0.3.0, which includes a breaking change in the optional additional fields parameter of logging function calls to ensure correctness and catch coding errors during compilation. Any early adopter provider logging which calls those functions may require updates. (#268)

BREAKING CHANGES:

• The ToTerraformValue method of the attr.Value interface now returns a tftypes.Value, instead of an interface{}. Existing types need to be updated to call tftypes.ValidateValue and tftypes.NewValue, passing the value they were returning before, instead of returning the value directly. (#231)
• tfsdk: The ListNestedAttributesOptions, MapNestedAttributeOptions, and SetNestedAttributeOptions type MaxItems and MinItems fields have been removed since the protocol and framework never supported this type of nested attribute validation. Use attribute validators instead. (#249)

ENHANCEMENTS:

• Added the ability to get an attribute as a generic attr.Value when using GetAttribute. (#232)
• Logging can now be used by calling tflog.Trace, tflog.Debug, tflog.Info, tflog.Warn, or tflog.Error. See the tflog docs for more information. (#234)
• tfsdk: Added Debug field to ServeOpts for running providers via debugger and testing processes (#243)

BUG FIXES:

• tfsdk: Removed Schema restriction that it must contain at least one attribute or block (#252)
• tfsdk: Support protocol version 5 and verify valid resource type in UpgradeResourceState RPC (#263)

0.5.0 (November 30, 2021)

BREAKING CHANGES:

• Fixed RequiresReplace and RequiresReplaceIf to be more judicious about when they require a resource to be destroyed and recreated. They will no longer require resources to be recreated when any attribute changes, instead limiting it only to the attribute they're declared on. They will also not require resources to be recreated when they're being created or deleted. Finally, they won't require a resource to be recreated if the user has no value in the config for the attribute and the attribute is computed; this is to prevent the resource from being destroyed and recreated when the provider changes the value without any user prompting. Providers that wish to destroy and recreate the resource when an optional and computed attribute is removed from the user's config should do so in their own plan modifier. (#213)
• RequiresReplaceIf no longer overrides previous plan modifiers' value for RequiresReplace if the function returns false. (#213)
• diag: The AttributeErrorDiagnostic and AttributeWarningDiagnostic types have been removed. Any usage can be replaced with DiagnosticWithPath. (#219)
• tfsdk: The AddAttributeError, AddAttributeWarning, AddError, and AddWarning methods on the ConfigureProviderResponse, CreateResourceResponse, DeleteResourceResponse, ModifyAttributePlanResponse, ModifyResourcePlanResponse, ReadDataSourceResponse, ReadResourceResponse, and UpdateResourceResponse types have been removed in preference of the same methods on the Diagnostics field of these types. For example, code such as resp.AddError("...", "...") can be updated to resp.Diagnostics.AddError("...", "..."). (#198)
• tfsdk: The Config, Plan, and State type GetAttribute methods now return diagnostics only and require the target as the last parameter, similar to the Get method. (#167)

FEATURES:

• Added tfsdk.UseStateForUnknown() as a built-in plan modifier, which will automatically replace an unknown value in the plan with the value from the state. This mimics the behavior of computed and optional+computed values in Terraform Plugin SDK versions 1 and 2. Provider developers will likely want to use it for "write-once" attributes that never change once they're set in state. (#204)
• tfsdk: Support list and set blocks in schema definitions (#188)

ENHANCEMENTS:

• diag: Added WithPath() function to wrap or overwrite diagnostic path information. (#219)
• tfsdk: The Config, Plan, and State type GetAttribute methods can now be used to fetch values directly into attr.Value implementations and Go types. (#167)

BUG FIXES:

• tfsdk: Fetch null values from valid missing Config, Plan, and State paths in GetAttribute() method (#185)
• types: Ensure Float64 Type() method returns Float64Type (#202)
• types: Prevent panic with uninitialized Number Value (#200)
• types: Prevent panics when ValueFromTerraform received nil values (#208)

0.4.2 (September 29, 2021)

BUG FIXES:

• Fix bug in which updating Computed-only attributes would lead to a "Provider produced inconsistent result after apply" error (#176/#184)

0.4.1 (September 27, 2021)

NOTES:

• Upgraded to terraform-plugin-go v0.4.0 which contains its own breaking changes. Please see https://github.com/hashicorp/terraform-plugin-go/blob/main/CHANGELOG.md#040-september-24-2021 for more details. (#179)

0.4.0 (September 24, 2021)

BREAKING CHANGES:

• attr.Type implementations must now have a String() method that returns a human-friendly name for the type. (#120)
• tfsdk: Resource implementations must now include the ImportState(context.Context, ImportResourceStateRequest, *ImportResourceStateResponse) method. If import is not supported, call the ResourceImportStateNotImplemented() function or return an error. (#149)

FEATURES:

• tfsdk: Support resource import (#149)
• types: Support Set and SetType (#126)
• types: Support for Float64, Float64Type, Int64, and Int64Type (#166)

ENHANCEMENTS:

• Added a tfsdk.ConvertValue helper that will convert any attr.Value into any compatible attr.Type. Compatibility happens at the terraform-plugin-go level; the type that the attr.Value's ToTerraformValue method produces must be compatible with the attr.Type's TerraformType(). Generally, this means that the attr.Type of the attr.Value and the attr.Type being converted to must both produce the same tftypes.Type when their TerraformType() method is called. (#120)

BUG FIXES:

• attr: Ensure List types implementing attr.TypeWithValidate call ElementType validation only if that type implements attr.TypeWithValidate (#126)
• tfsdk: (Plan).SetAttribute() and (State).SetAttribute() will now create missing attribute paths instead of silently failing to update. (#165)

0.3.0 (September 08, 2021)

BREAKING CHANGES:

• Methods on the tfsdk.Config, tfsdk.Plan, and tfsdk.State types now return []*tfprotov6.Diagnostic instead of error (#82)
• Most uses of []*tfprotov6.Diagnostic have been replaced with a new diag.Diagnostics type. Please update your type signatures, and use one of the diags.New* helper functions instead of constructing *tfprotov6.Diagnostics by hand. (#110)
• The schema.Attribute and schema.Schema types have been moved to tfsdk.Attribute and tfsdk.Schema. No changes beyond import names are required. (#77)
• With the release of Go 1.17, Go 1.17 is now the lowest supported version of Go to use with terraform-plugin-framework. (#104)
• attr.Value implementations must now implement a Type(context.Context) method that returns the attr.Type that created the attr.Value. (#119)

FEATURES:

• Added support for ModifyPlan functions on Resources. (#90)
• Introduced first-class diagnostics (diag package). (#110)
• Support attr.Type validation (#82)
• tfsdk: Attributes, Data Sources, Providers, and Resources now support configuration validation (#75)

ENHANCEMENTS:

• Added a tfsdk.ValueAs helper that allows accessing an attr.Value without type assertion, by using the same reflection rules used in the Config.Get, Plan.Get, and State.Get helpers. (#119)
• Errors from methods on the tfsdk.Config, tfsdk.Plan, and tfsdk.State types now include rich diagnostic information (#82)
• tfsdk: Validate Attribute defines at least one of Required, Optional, or Computed (#111)

BUG FIXES:

• tfsdk: Diagnostics returned from (Plan).SetAttribute() and (State).SetAttribute() reflection will now properly include attribute path (#133)
• tfsdk: Don't attempt validation on the nested attributes of a null or unknown SingleNestedAttribute (#118)
• tfsdk: Return warning diagnostic when using Attribute or Schema type DeprecationMessage field (#93)

0.2.0 (July 22, 2021)

ENHANCEMENTS:

• Added tfsdk.NewProtocol6Server to return a tfprotov6.ProviderServer implementation for testing and muxing purposes. (#72)
• Added support for MapNestedAttributes. (#79)
• Responses now default to returning the current state, meaning state will only change when provider developers actively change it. Previously, an empty state value would be returned, which caused problems. (#74)

0.1.0 (June 24, 2021)

FEATURES:

• Added interfaces extending the attr.Type interface to include attribute and element types. (#44)
• Added state, config, and plan types, and support for getting values from them. (#46)
• Added support for Object types. (#38)
• Added support for bools, numbers, and strings. (#29)
• Added support for defining schemas and attributes. (#27)
• Added support for lists. (#36)
• Added support for maps. (#37)
• Added support for provider, resource, and data source types. (#32)
• Added the ability to serve providers. (#45)
