Services

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

SDK Breaking changes

  • This update includes breaking changes to how the DynamoDB AttributeValue (un)marshier handles empty collections.

Deprecations

  • service/s3/s3crypto: Deprecates the crypto client from the SDK (#394)
    • s3crypto client is now deprecated and may be removed from the future versions of the SDK.
  • aws: Removes plugin credential provider (#391)
    • Removing plugin credential provider from the v2 SDK developer preview. This feature may be made available as a separate module.
  • Removes support for deprecated Go versions (#393)
    • Removes support for Go version specific files from the SDK. Also removes irrelevant build tags, and updates the README.md file.
    • Raises the minimum supported version to Go 1.11 for the SDK. Older versions may work, but are not actively supported

SDK Features

  • service/s3/s3manager: Add Upload Buffer Provider (#404)
    • Adds a new BufferProvider member for specifying how part data can be buffered in memory.
    • Windows platforms will now default to buffering 1MB per part to reduce contention when uploading files.
    • Non-Windows platforms will continue to employ a non-buffering behavior.
  • service/s3/s3manager: Add Download Buffer Provider (#404)
    • Adds a new BufferProvider member for specifying how part data can be buffered in memory when copying from the http response body.
    • Windows platforms will now default to buffering 1MB per part to reduce contention when downloading files.
    • Non-Windows platforms will continue to employ a non-buffering behavior.
  • service/dynamodb/dynamodbattribute: New Encoder and Decoder Behavior for Empty Collections (#401)
    • The Encoder and Decoder types have been enhanced to support the marshaling of empty structures, maps, and slices to and from their respective DynamoDB AttributeValues.
    • This change incorporates the behavior changes introduced via a marshal option in V1 (#2834)

SDK Enhancements

  • internal/awsutil: Add suppressing logging sensitive API parameters (#398)
    • Adds suppressing logging sensitive API parameters marked with the sensitive trait. This prevents the API type's String method returning a string representation of the API type with sensitive fields printed such as keys and passwords.
    • Related to aws/aws-sdk-go#2310
    • Fixes #251
  • aws/request : Retryer is now a named field on Request. (#393)
  • service/s3/s3manager: Adds sync.Pool to allow reuse of part buffers for streaming payloads (#404)
    • Fixes #402
    • Uses the new behavior introduced in V1 #2863 which allows the reuse of the sync.Pool across multiple Upload request that match part sizes.

SDK Bugs

  • service/s3/s3manager: Fix index out of range when a streaming reader returns -1 (#378)
    • Fixes the S3 Upload Manager's handling of an unbounded streaming reader that returns negative bytes read.
  • internal/ini: Fix ini parser to handle empty values #406
    • Fixes incorrect modifications to the previous token value of the skipper. Adds checks for cases where a skipped statement should be marked as complete and not be ignored.
    • Adds tests for nested and empty field value parsing, along with tests suggested in aws/aws-sdk-go#2801
