0.22.1 (March 11, 2024)

NOTES:

  • all: Upgraded google.golang.org/protobuf dependency, which includes a fix for CVE-2024-24786. While the fixed feature is not used in this Go module, this upgrade may silence security vulnerability scanner reports that are based purely on dependency versions. (#385)

BUG FIXES:

  • tftypes: Fixed an edge-case where (Value).Equal would panic when comparing two values with underlying DynamicPseudoType types and different concrete values. (#383)

0.22.0 (February 22, 2024)

0.19.0 (September 06, 2023)

NOTES:

  • all: If using terraform-plugin-framework, terraform-plugin-mux, or terraform-plugin-sdk, only upgrade this Go module when upgrading those Go modules or you may receive a missing GetMetadata method error when compiling (#310)
  • all: This Go module has been updated to Go 1.20 per the Go support policy. It is recommended to review the Go 1.20 release notes before upgrading. Any consumers building on earlier Go versions may experience errors. (#321)

ENHANCEMENTS:

  • tfprotov5: Added DynamicValue type IsNull method, which enables checking if the value is null without type information and fully decoding underlying data (#305)
  • tfprotov6: Added DynamicValue type IsNull method, which enables checking if the value is null without type information and fully decoding underlying data (#305)

0.16.0 (June 16, 2023)

ENHANCEMENTS:

  • all: Improved SDK logging performance when messages would be skipped due to configured logging level (#289)

NOTES:

  • all: This Go module has been updated to Go 1.19 per the Go support policy. It is recommended to review the Go 1.19 release notes before upgrading. Any consumers building on earlier Go versions may experience errors. (#266)

0.14.3 (January 5, 2023)

BUG FIXES:

  • tfprotov5/tf5server: Prevented TF_LOG_SDK_PROTO_DATA_DIR file overlap by switching from second to millisecond file naming granularity (#245)
  • tfprotov6/tf6server: Prevented TF_LOG_SDK_PROTO_DATA_DIR file overlap by switching from second to millisecond file naming granularity (#245)

0.14.2 (November 22, 2022)

BUG FIXES:

  • tfprotov5: Allow diagnostic messages with incorrect UTF-8 encoding to pass through with the invalid sequences replaced with the Unicode Replacement Character. This avoids returning the unhelpful message "string field contains invalid UTF-8" in that case. (#237)
  • tfprotov6: Allow diagnostic messages with incorrect UTF-8 encoding to pass through with the invalid sequences replaced with the Unicode Replacement Character. This avoids returning the unhelpful message "string field contains invalid UTF-8" in that case. (#237)

0.14.1 (November 8, 2022)

NOTES:

  • No expected changes with this Go module's functionality. Contains updates to dependencies such as google.golang.org/grpc and github.com/hashicorp/go-plugin, which may be beneficial for consumers.

0.14.0 (August 15, 2022)

NOTES:

  • This Go module has been updated to Go 1.18 per the Go support policy. Any consumers building on earlier Go versions may experience errors. (#219)

  • tftypes: Clarified ValueFromJSON error messaging with object attribute key issues (#214)

0.12.0 (July 15, 2022)

NOTES:

  • The underlying terraform-plugin-log dependency has been updated to v0.6.0, which includes log filtering support and breaking changes of With() to SetField() function names. Any provider logging which calls those functions may require updates. (#209)

0.11.0 (July 8, 2022)

FEATURES:

  • Added support for protocol version 5.3 and 6.3, which allows providers to opt into the PlanResourceChange RPC for resource destruction (#205)

ENHANCEMENTS:

  • tfprotov5: Added ServerCapabilities type and ServerCapabilities field to GetProviderSchemaResponse (#205)
  • tfprotov6: Added ServerCapabilities type and ServerCapabilities field to GetProviderSchemaResponse (#205)

NOTES:

  • This Go module has been updated to Go 1.17 per the Go support policy. Any consumers building on earlier Go versions may experience errors. (#175)

ENHANCEMENTS:

  • tftypes: Added Type support to WalkAttributePath() function (#163)

BUG FIXES:

  • tfprotov5/tf5server: Ensured @caller in protocol logging entries accurately reflected calling code location (#179)
  • tfprotov6/tf6server: Ensured @caller in protocol logging entries accurately reflected calling code location (#179)

0.8.0 (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. (#166)

ENHANCEMENTS:

  • tfprotov5: Added ValueType() methods to Schema, SchemaAttribute, SchemaBlock, and SchemaNestedBlock types. (#158)
  • tfprotov6: Added ValueType() methods to Schema, SchemaAttribute, SchemaBlock, SchemaNestedBlock, and SchemaObject types. (#158)

0.7.1

BUG FIXES:

  • tfprotov5/tf5server: Ensure server options are passed through on startup (#153)
  • tfprotov5/tf5server: Prevent empty provider address error logs on startup (#150)

0.7.0 (January 20, 2022)

BREAKING CHANGES:

  • tfprotov6: The SchemaObject.MaxItems and SchemaObject.MinItems fields have been removed without replacement. These were never used in the protocol and did not perform any validation. (#143)

BUG FIXES:

  • tfprotov6: The ApplyResourceChangeResponse.UnsafeToUseLegacyTypeSystem and PlanResourceChangeResponse.UnsafeToUseLegacyTypeSystem fields are now properly passed into and out of the protocol (#143)

0.6.0 (January 18, 2022)

ENHANCEMENTS:

  • tfprotov5/tf5server: Added WithManagedDebug() ServeOpt, which implements outputting reattach configuration to stdout and stopping on SIGINT (#137)
  • tfprotov5/tf5server: Added support for writing protocol data to disk by setting TF_LOG_SDK_PROTO_DATA_DIR environment variable (#135)
  • tfprotov5/tf5server: Increased maximum gRPC send and receive message size limit to 256MB (#139)
  • tfprotov6/tf6server: Added WithManagedDebug() ServeOpt, which implements outputting reattach configuration to stdout and stopping on SIGINT (#137)
  • tfprotov6/tf6server: Added support for writing protocol data to disk by setting TF_LOG_SDK_PROTO_DATA_DIR environment variable (#135)
  • tfprotov6/tf6server: Increased maximum gRPC send and receive message size limit to 256MB (#139)

BUG FIXES:

  • Prevent potential process leak on Windows platforms (#123)
  • tftypes: Fixed regression with DynamicPseudoType handling since v0.4.0, allowing usage of known values again and preventing msgpack decoding errors in Terraform CLI (#136)

0.5.0 (December 07, 2021)

BREAKING CHANGES:

  • tf6server.New and tf5server.New now accept a name argument (meant to be the full registry path of the provider, e.g. registry.terraform.io/hashicorp/random) and a variadic argument of ServeOpts, just like the Serve function. Providers calling Serve will not notice any change. Providers calling New directly should pass the name and any options they would like the server to be configured with. (#93)

FEATURES:

  • Added support for terraform-plugin-log v0.2.0, injecting loggers for SDKs and the provider into requests and adding trace and error log lines to request handlers. (#93)

ENHANCEMENTS:

  • New WithoutLogStderrOverride, WithLogEnvVarName, and WithoutLogLocation ServeOpt helper functions have been added to tf6server and tf5server. These helpers can be passed to Serve or New to control logging behaviors for SDK and provider logs. WithoutLogStderrOverride disables using the stderr that existed at startup instead of the one that exists when the log function is called; it is recommended to not use this unless you understand the impacts, as Terraform's default behavior is counter-intuitive. WithLogEnvVarName sets the name of the provider's log module and controls what follows TF_LOG_PROVIDER_ as the environment variable to control the log's level. WithoutLogLocation excludes filename and line numbers from log output. (#93)
  • tftypes: Added AttributePath LastStep() method and AttributePathStep Equal() method (#112)

BUG FIXES:

  • Fixed a panic when using DynamicPseudoType attributes in an object. (#116)
  • tftypes: Return null Number when NewValue receives (*big.Float)(nil) (#114)

0.4.0 (September 24, 2021)

BREAKING CHANGES:

  • The AttributeType property of tftypes.Map has been renamed to ElementType. (#105)
  • The tf5server package's import path is now github.com/hashicorp/terraform-plugin-go/tfprotov5/tf5server instead of github.com/hashicorp/terraform-plugin-go/tfprotov5/server. (#103)
  • The tf6server package's import path is now github.com/hashicorp/terraform-plugin-go/tfprotov6/tf6server instead of github.com/hashicorp/terraform-plugin-go/tfprotov6/server. (#103)
  • With the release of Go 1.17, Go 1.16 is now the lowest supported version of Go to use with terraform-plugin-go. (#102)
  • tftypes: The Is() method on types implementing the Type interface now only perform a shallow type check, no longer comparing any underlying attribute or element type(s). Use the Equal() method for deep type checking. (#94)
  • tftypes: (AttributePath).WithElementKeyInt() now has an int parameter instead of int64. Using (AttributePath).WithElementKeyInt() within for ... range loops no longer requires int64() conversion. (#101)

ENHANCEMENTS:

  • tftypes: All types implementing the Type interface now provide an Equal() method for deep type checking and UsableAs() method for type conformance checking. (#94)

BUG FIXES:

  • tftypes: Ensure NewValue() panics on DynamicPseudoType and known values. (#94)
  • tftypes: Fixed elements of Tuple and Map and attributes of Object having DynamicPseudoType as their type when unmarshaling JSON values from Terraform. (#94)
  • tftypes: Fixed elements of Tuple and Map and attributes of Object having DynamicPseudoType as their type when unmarshaling msgpack values from Terraform. (#100)
  • tftypes: Prevent potential panic unmarshaling null DynamicPseudoType in msgpack (#99)
  • tftypes: Return error instead of panic when calling (Value).Diff() with either Value missing type (#104)
  • tftypes: Return error instead of panic when calling Transform() with Value missing type (#104)

0.3.1 (June 24, 2021)

BUG FIXES:

  • Fixed AttributePaths pointing to the root of the value to be omitted instead of prefixing the error with : . (#87)
  • Fixed a panic when .String() is called on an empty tftypes.Value. (#86)
  • Fixed a panic when calling tftypes.Value.As and passing a pointer to an uninstantiated *big.Float. (#85)
  • Fixed a panic when calling tftypes.Value.As and passing a pointer to an uninstantiated *bool, *string, *map[string]Value or *[]Value. (#88)
  • Fixed a panic when comparing the empty value of a tftypes.Value to a non-empty value. (#90)

0.3.0 (April 21, 2021)

BREAKING CHANGES:

  • Previously, tftypes.NewValue would panic if the Go type supplied wasn't a valid Go type for any tftypes.Type. Now tftypes.NewValue will panic if the Go type supplied isn't a valid Go type for the specific tftypes.Type supplied. (#67)
  • Removed support for *float32 (and float32, which was only documented and never implemented) when creating a tftypes.Number using tftypes.NewValue. We can't find a lossless way to convert a float32 to a *big.Float and so require provider developers to choose the lossy conversion they find acceptable. (#67)
  • Removed the now-unnecessary tftypes.ValueComparer helper, which helped github.com/google/go-cmp compare tftypes.Values. tftypes.Values now have an Equal method that go-cmp can use, and don't need any special options passed anymore. (#67)
  • The tftypes package has been moved to the root of the module and is no longer under the tfprotov5 package. Providers can automatically rewrite their import paths using a command like sed -i 's/"github.com\/hashicorp\/terraform-plugin-go\/tfprotov5\/tftypes"/"github.com\/hashicorp\/terraform-plugin-go\/tftypes"/g' **/*.go on Unix-like systems. (#70)
  • With the release of Go 1.16, Go 1.15 is now the lowest supported version of Go to use with terraform-plugin-go. (#62)
  • tftypes.AttributePath is now referenced as a pointer instead of a value pretty much everywhere it is used. This enables much more ergonomic use with tfprotov5.Diagnostic values. (#68)
  • tftypes.AttributePath's Steps property is now internal-only. Use tftypes.AttributePath.Steps() to access the list of tftypes.AttributePathSteps, and tftypes.NewAttributePath or tftypes.NewAttributePathWithSteps to create a new tftypes.AttributePath. (#68)
  • tftypes.String, tftypes.Number, tftypes.Bool, and tftypes.DynamicPseudoType are now represented by a different Go type. Uses of == and switch on them will no longer work. The recommended way to compare any type is using Is. (#58)
  • tftypes.Values no longer have an Is method. Use tftypes.Value.Type().Is instead. (#58)
  • tftypes.AttributePath.WithAttributeName, WithElementKeyString, WithElementKeyInt, and WithElementKeyValue no longer accept pointers and mutate the AttributePath. They now copy the AttributePath, and return a version of it with the new AttributePathStep appended. (#60)

FEATURES:

  • Added tftypes.Diff function to return the elements and attributes that are different between two tftypes.Values. (#60)
  • Added tftypes.Walk and tftypes.Transform functions for the tftypes.Value type, allowing providers to traverse and mutate a tftypes.Value, respectively. (#60)
  • tftypes.Values now have a Type method, exposing their tftypes.Type. (#58)

ENHANCEMENTS:

  • A number of methods in tftypes are benefitting from a better error message for tftypes.AttributePathErrors, which are returned in various places, and will now surface the path associated with the error as part of the error message. (#68)
  • Added Equal method to tftypes.Type implementations, allowing them to be compared using github.com/google/go-cmp. (#74)
  • Added a Copy method to tftypes.Value, returning a clone of the tftypes.Value such that modifying the clone is guaranteed to not modify the original. (#60)
  • Added a String method to tftypes.AttributePath to return a string representation of the tftypes.AttributePath. (#60)
  • Added a String method to tftypes.Value, returning a string representation of the tftypes.Value. (#60)
  • Added a tftypes.ValidateValue function that returns an error if the combination of the tftypes.Type and Go type passed when panic when passed to tftypes.NewValue. (#67)
  • Added an Equal method to tftypes.AttributePath to compares two tftypes.AttributePaths. (#60)
  • Added an Equal method to tftypes.Value to compare two tftypes.Values. (#60)
  • Added support for OptionalAttributes to tftypes.Objects, allowing for objects with attributes that can be set or can be omitted. See https://www.terraform.io/docs/language/expressions/type-constraints.html#experimental-optional-object-type-attributes for more information on optional attributes in objects. (#74)
  • Added support for uint, uint8, uint16, uint32, uint64, int, int8, int16, int32, int64, and float64 conversions when creating a tftypes.Number with tftypes.NewValue. These were mistakenly omitted previously. (#67)
  • Added support for version 6 of the Terraform protocol, in a new tfprotov6 package. (#71)
  • Updated the String method of all tftypes.Type implementations to include any element or attribute types in the string as well. (#60)
  • tftypes.AttributePathError is now exported. Provider developers can use errors.Is and errors.As to check for tftypes.AttributePathErrors, errors.Unwrap to get to the underlying error, and the Path property on a tftypes.AttributePathError to access the tftypes.AttributePath the error is associated with. tftypes.AttributePath.NewError and tftypes.AttributePath.NewErrorf are still the supported ways to create a tftypes.AttributePathError. (#68)

BUG FIXES:

  • Fixed a bug in tftypes.Value.IsFullyKnown that would cause a panic when calling IsFullyKnown on tftypes.Value with a tftypes.Type of Map, Object, List, Set, or Tuple if the tftypes.Value was null. (#69)
  • Fixed a bug where *uint8, *uint16, and *uint32 would be coerced to int64s as part of their conversion in tftypes.NewValue. This may have had no impact, as all those types can be represented in an int64, but to be sure our conversion is accurate, the conversion was fixed to convert them to a uint64 instead. (#67)

0.2.1 (January 07, 2021)

BUG FIXES:

  • Fixed a bug that could cause a crash when a provider was prematurely stopped. (#49)

0.2.0 (November 20, 2020)

ENHANCEMENTS:

  • tftypes.NewValue can now accept a wider array of standard library types which will be automatically converted to their standard representation (#46] [#47)
  • tfprotov5.RawState now has an Unmarshal method, just like tfprotov5.DynamicValue, yielding a tftypes.Value. (#42)

0.1.0 (November 02, 2020)

Initial release.
