  • Fixes #359

SDK Features

SDK Enhancements

Release v0.10.0 (2019-07-24)

Services

• Synced the V2 SDK with latest AWS service API definitions.
• Fixes #341
• Fixes #342

SDK Breaking Changes

• aws: Add default HTTP client instead of http.DefaultClient/Transport (#315)
  • Adds a new BuildableHTTPClient type to the SDK's aws package. The type uses the builder pattern with immutable changes. Modifications to the buildable client create copies of the client. Adds a HTTPClient interface to the aws package that the SDK will use as an abstraction over the specific HTTP client implementation. The SDK will default to the BuildableHTTPClient, but a *http.Client can be also provided for custom configuration. When the SDK's aws.Config.HTTPClient value is a BuildableHTTPClient the SDK will be able to use API client specific request timeout options.
  • Fixes #279
  • Fixes #269

SDK Enhancements

• service/s3/s3manager: Update S3 Upload Multipart location (#324)
  • Updates the Location returned value of S3 Upload's Multipart UploadOutput type to be consistent with single part upload URL. This update also brings the multipart upload Location inline with the S3 object URLs created by the SDK.

  • V2 Port aws/aws-sdk-go#2453

SDK Bugs

• private/model: Handles empty map vs unset map behavior in send request (#337)

  • Fix #332
• service/rds: Fix presign URL for same region (#331)
  • Fixes RDS no-autopresign URL for same region issue for aws-sdk-go-v2. Solves the issue by making sure that the presigned URLs are not created, when the source and destination regions are the same. Added and updated the tests accordingly.
  • Fix #271
• private/protocola/json/jsonutil: Fix Unmarshal map[string]bool (#320)
  • Fixes the JSON unmarshaling of maps of bools. The unmarshal case was missing the condition for bool value, in addition the bool pointer.
  • Fix #319

Release v0.9.0 (2019-05-28)

Services

• Synced the V2 SDK with latest AWS service API definitions.
• Fixes #304
• Fixes #295

SDK Breaking changes

This update includes multiple breaking changes to the SDK. These updates improve the SDK's usability, consistency.

Client type name

The API client type is renamed to Client for consistency, and remove stutter between package and client type name. Using Amazon S3 API client as an example, the s3.S3 type is renamed to s3.Client.

New API operation response type

API operations' Request.Send method now returns a Response type for the specific operation. The Response type wraps the operation's Output parameter, and includes a method for the response's metadata such as RequestID. The Output type is an anonymous embedded field within the Output type. If your application was passing the Output value around you'll need to extract it directly, or pass the Response type instead.

New API operation paginator utility

This change removes the Paginate method from API operation Request types, (e.g. ListObjectsRequest). A new Paginator constructor is added that can be used to page these operations. To update your application to use the new pattern, where Paginate was being called, replace this with the Paginator type's constructor. The usage of the returned Paginator type is unchanged.

req := svc.ListObjectsRequest(params)
p := req.Paginate()

Is updated to to use the Paginator constructor instead of Paginate method.

req := svc.ListObjectsRequest(params)
p := s3.NewListObjectsPaginator(req)

Other changes

• Standardizes API client package name to be based on the API model's ServiceID.
• Standardizes API client operation input and output type names.
• Removes endpoints package's service identifier constants. These values were unstable. Each API client package contains an EndpointsID constant that can be used for service specific endpoint lookup.
• Fix API endpoint lookup to use the API's modeled EndpointsID (aka enpdointPrefix). Searching for API endpoints in the endpoints package should use the API client package's, EndpointsID.

SDK Enhancements

• Update CI tests to ensure all codegen changes are accounted for in PR (#183)

• Updates the CI tests to ensure that any code generation changes are accounted for in the PR, and that there were no mistaken changes made without also running code generation. This change should also help ensure that code generation order is stable, and there are no ordering issues with the SDK's codegen.

  • Related aws/aws-sdk-go#2617

Release v0.8.0 (2019-04-25)

Services

• Synced the V2 SDK with latest AWS service API definitions.

SDK Breaking changes

• Update SDK API operation request send to required Context (#265)
  • Updates the SDK's API operation request Send method to require a context.Context value when called. This is done to encourage best applications to use Context for cancellation and request tracing. Standardizing on this pattern will also help reduce code paths which accidentally do not have the Context causing the cancellation and tracing chain to be lost. Leading to difficult to trace down losses of cancellation and tracing within an application.
  • Fixes #264

SDK Enhancements

• Update README.md for getting SDK without Go Modules
  • Updates the README.md with instructions how to get the SDK without Go Modules enabled, or using the SDK within a GOPATH with Go 1.11, and Go 1.12.
• Refactor SDK's integration tests to be code generated (#283)
• aws: Add RequestThrottledException to set of throttled exceptions (#292)
• private/model/api: Backfill authtype, STS and Cognito Identity (#293)
  • Backfills the authtype=none modeled trait for STS and Cognito Identity services. This removes the in code customization for these two services' APIs that should not be signed.

SDK Bugs

• Fix HTTP endpoint credential provider test for unresolved hosts (#262)
  • Fixes the HTTP endpoint credential provider's tests to check for a host that resolves to no addresses.
• example/service/s3/mockPaginator: Update example to not use internal pkg (#278)
  • Updates the SDK's S3 Mock Paginator example to not use internal SDK packages and instead use the SDK's provided defaults package for default configuration.
  • Fixes #116
• Cleanup go mod unused dependencies (#284)
• service/s3/s3manager: Fix brittle Upload unit test (#288)
• aws/ec2metadata: Fix EC2 Metadata client panic with debug logging (#290)
  • Fixes a panic that could occur within the EC2 Metadata client when both AWS_EC2_METADATA_DISABLED env var is set and log level is LogDebugWithHTTPBody. The SDK's client response body debug functionality would panic because the Request.HTTPResponse value was not specified.
• aws: Fix RequestUserAgent test to be stable (#289)
• private/protocol/rest: Trim space in header key and value (#291)
  • Fixes a bug when using S3 metadata where metadata values with leading spaces would trigger request signature validation errors when the request is received by the service.
