June 8th, 2021: 9 new services added

New this Week

• 🎉 Add support for MediaLive and MediaPackage (#449, @Alastaim)
• 🎉 Add support for SNS (#450)

June 1st, 2021: SQS & ECS support

New this week:

• 🎉 Add support for SQS. SQS is our first service to use the awsQuery protocol. Please report any issues you may encounter.
• 🎉 Add support for ECS.
• Breaking Change: Refactored smithy_types::Error to be more flexible. Internal fields of Error are now private and can now be accessed accessor functions. (#426)
• ByteStream::from_path now accepts implications AsRef<Path> (@LMJW)
• Add support for S3 extended request id (#429)

Smithy Internals

• Rewrite JSON serializer (#411, #423, #416, #427)

May 25th 2021: S3 & SSM support

New This Week

• 🎉 Add S3 support. S3 is the first protocol to use our new XML serializers which increases the likelihood of undiscovered issues. In addition, virtual addressing, dualstack and transfer acceleration are not currently supported. Please try it out and let us know if you run into any problems! (#398) 🎉
• 🎉 Add support for SSM. SSM was prioritized based on your votes—Please keep voting for the services and feature most important to you! (#393) 🎉
• Add request/response tracing. These can be enabled via tracing subscriber by setting: RUST_LOG='smithy_http_tower::dispatch=trace,smithy_http::middleware=trace' (#397)
• Bugfix: Generated service docs were missing at the module level (#404)
• ByteStream can now be created from Path and File via ByteStream::from_path (#412)
• Example code now uses write_all_buf (#408, @LMJW)
• The Authorization and x-amz-security-token headers are now marked as sensitive and will be omitted from logs even when full request/response tracing is enabled

---

Updates to internals:

• Full restXML protocol support
• Enum variants are now properly escaped (#388)
• x-amz-useragent and x-amz-date headers are now signed (required for S3)

This release will be built into aws-sdk-rust:v0.0.5-alpha
Thanks!

May 18th 2021

New this week:

• 🎉 Add support for AWS Lambda (#361, @richardhboyd) 🎉
• Breaking change (technically, no services impacted): Add support for streaming request bodies. When Blob is marked as a streaming request type, the SDK now generates ByteStream instead. (#359)
• Types represented by the Smithy Set type now generate Vec<T> in all cases (#270)
• Bugfix: The .message()field of errors will now look for both message and Message in the model (#374)
• Add support for the AWS_REGION environment variable. (#362)
• The request type generated by the fluent builders, eg. dynamodb.list_tables() is now Debug (#377, @declanvk)

Updates to Internals:

• Recursive Inline dependencies are supported via a fixed-point algorithm
• restXML deserialization support
• Overhaul of URL encoding during request serialization, fixing several bugs (#368)
• Update signer to avoid cloning credentials (#341)

May 6th Alpha Release

New this week:

• Fix stack overflow in SdkBody Debug implementation (#343)
• Upgrade to Smithy 1.7. This adds support for several new API Gateway endpoints (#340)
• Add support for streaming response bodies. This is currently only used in Polly (#338)
• Added code examples for Kinesis (#306)

• @shinglyu
• @Doug-AWS
• @rcoh

Thanks!

April 27th Alpha RC2

New this week

• Added QLDB & QLDB Session support (@marcbowes)
• New examples for secrets manager. (@nataibi, @Doug-AWS )
• Examples for Kinesis, DynamoDb & Amazon Polly (@Doug-AWS )
• Added support for RusTLS. This is now the default. You can switch back to native-tls with default-features = false, features = ["native-tls", "client"]
• Unions like AttributeValue now have is_xyz and as_xyz methods. (@barbu110)
• Bugfix: An empty body could cause an empty H2 frame to be sent.
• Clients are now Clone + Debug (@shinglyu)
• Generated crates have been renamed to aws-sdk-*
• Credentials are now zero'd when they are dropped
• Event stream operations which wouldn't work are not generated

Public Alpha RC1 4-7-2021

New this week:

• Support for 2 new services (& the restJson protocol!): This release adds support for ApiGateway and Amazon Polly. As these are the first two services with the new protocol, bugs are more likely than usual. Please let us know if you hit any issues. New examples have been added.
• New error shapes: Each generated service now generates a <service_name>::Error struct. This is a superset of all errors that the service emits & can be used to write unified error handling that works across all operations on the same service:

  #[tokio::main]
  async fn main() -> Result<(), dynamodb::Error> {
     let client = dynamodb::Client::from_env();
     client.list_tables().send().await?; // All operation errors impl `Into<dynamodb::Error>`
  }

• Breaking Change: Generated builders are Vec and HashMap aware: Builder objects now generate special case builders when the argument is a Set or HashMap (#267). These builders accept an element of the Vec or HashMap and append to the builder, creating a collection if it did not previously exist. If you need to pass a Vec or HashMap directly to the builder, use builder.set_xyz(Some(v)) instead of builder.xyz(v).
• Breaking Change: High level clients are now exported in <servicename>::Client instead of <servicename>::fluent::Client
• Bugfix: The futures produced by clients were not Send which made them unusable for tokio::spawn. This has been resolved.

The generated code has been pushed to https://github.com/awslabs/smithy-rs/releases/tag/v0.6-rc1.cargo

Fluent client, error refactoring, concrete response bodies

New this week:

• A "fluent" ergonomic client is available in dynamodb::fluent (and for all other services). At the cost of some flexibility, this offers an API with fewer moving parts that is generally a little more ergonomic to use. The old API is still available. This is enabled via the fluent feature which is enabled by default & brings in aws-hyper as a default transport. Breaking: To preserve the old behavior, add default-features = false
• Breaking change: Errors have been refactored to expose their "kind" separate from metadata. In general, you can simply add .kind to existing code.
• SdkResult/SdkError are no longer generic in B, the response body. Instead, a concrete ResponseBody is provided by the SDK that is optimized for the specific use case.

Retries, new client connection managment

New this week:

• Retry support. Note: If you are using client from the main branch be sure to upgrade. A major bug in the retry code landed although it was never in a release (#238). These support:
  • Modeled retries
  • The Retry-After header
  • Error Code based retries
  • Http Status based retries
• Improved client connection management (#237). Previously, if you had an aws_hyper::Client it was generic in C, the underlying Http connection. This made storing a client in a struct a little cumbersome. We have introduced a Standard connection that can still be swapped internally for use in tests but avoids the need for client code to manage a generic parameter.
• New usage examples. The "Movies" DynamoDB example has been ported to Rust and is now included in the examples folder. This also includes an example of a hand-written waiter. (#205)
• Docs are now generated for union variants (previously missing)

Compatibility:

• A number of pseudo internal APIs have been renamed. Consult the diff if you encounter issues.
