[dependabot-preview]

Bumps github.com/aws/aws-sdk-go-v2 from 0.19.0 to 0.20.0.

Release notes

Sourced from github.com/aws/aws-sdk-go-v2's releases.

Release v0.20.0 (2020-03-17)

Breaking Change

• Update SDK retry behavior
  • Significant updates were made the SDK's retry behavior. The SDK will now retry all connections error. In addition, to changing what errors are retried the SDK's retry behavior not distinguish the difference between throttling errors, and regular retryable errors. All errors will be retried with the same backoff jitter delay scaling.
  • The SDK will attempt an operation request 3 times by default. This is one less than the previous initial request with 3 retires.
  • New helper functions in the new aws/retry package allow wrapping a Retrier with custom behavior, overriding the base Retrier, (e.g. AddWithErrorCodes, and AddWithMaxAttempts)
• Update SDK error handling
  • Updates the SDK's handling of errors to take advantage of Go 1.13's new errors.As, Is, and Unwrap. The SDK's errors were updated to satisfy the Unwrap interface, returning the underlying error.
  • With this update, you can now more easily access the SDK's layered errors, and meaningful state such as, Timeout, Temporary, and other states added to the SDK such as CanceledError.
• Bump SDK minimum supported version from Go 1.12 to Go 1.13
  • The SDK's minimum supported version is bumped to take advantage of Go 1.13's updated errors package.

Services

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

SDK Features

• aws: Add Support for additional credential providers and credential configuration chaining (#488)
  • aws/processcreds: Adds Support for the Process Credential Provider
    • Fixes #249
  • aws/stscreds: Adds Support for the Web Identity Credential Provider
    • Fixes #475
    • Fixes #338
  • Adds Support for credential_source
    • Fixes #274
• aws/awserr: Adds support for Go 1.13's errors.Unwrap (#487)
• aws: Updates SDK retry behavior (#487)
  • aws/retry: New package defining logic to determine if a request should be retried, and backoff.
  • aws/ratelimit: New package defining rate limit logic such as token bucket used by the retry.Standard retrier.

SDK Enhancements

• aws: Add grouping of concurrent refresh of credentials (#503)
  • Concurrent calls to Retrieve are now grouped in order to prevent numerous synchronous calls to refresh the credentials. Replacing the mutex with a singleflight reduces the overall amount of time request signatures need to wait while retrieving credentials. This is improvement becomes pronounced when many requests are made concurrently.
• service/s3/s3manager: Improve memory allocation behavior by replacing sync.Pool with custom pool implementation
  • Improves memory allocations that occur when the provided io.Reader to upload does not satisfy both the io.ReaderAt and io.ReadSeeker interfaces.

SDK Bugs

• service/s3/s3manager: Fix resource leaks when the following occurred:
  • Failed CreateMultipartUpload call
  • Failed UploadPart call
