LambdaSharp "Hicetas" Release (v0.8.3.4) - 2021-07-15

Hicetas was a Greek philosopher of the Pythagorean School. He was born in Syracuse. Like his fellow Pythagorean Ecphantus and the Academic Heraclides Ponticus, he believed that the daily movement of permanent stars was caused by the rotation of the Earth around its axis. When Copernicus referred to Nicetus Syracusanus (Nicetus of Syracuse) in De revolutionibus orbium coelestium as having been cited by Cicero as an ancient who also argued that the Earth moved, it is believed that he was actually referring to Hicetas. (Wikipedia)

What's New

This release introduces some key new capabilities for Lambda functions and the LambdaSharp.Core module. The ALambdaFunction base class has new methods for sending events, capturing metrics, and logging debug statements. In addition, the LambdaSharp.Core module now uses Amazon Kinesis Firehose for ingesting CloudWatch Log streams. Kinesis Firehose is more cost effective, scales automatically, and also provides built-in integration with S3 for retaining ingested logs. Finally, during the ingestion process, the logs are converted into queryable JSON documents.

Upgrading from v0.7 to v0.8

1. Ensure all modules are deployed with v0.6.1 or later
2. Upgrade LambdaSharp CLI to v0.8
   1. dotnet tool update -g LambdaSharp.Tool
3. Upgrade LambdaSharp Deployment Tier (replace Sandbox with the name of the deployment tier to upgrade)
   1. lash init --allow-upgrade --tier Sandbox

BREAKING CHANGES

LambdaSharp Core Services

LambdaSharp.Core

Some configuration parameters changed with the switch to Amazon Kinesis Firehose for CloudWatch logs ingestion.

• The LoggingStreamRetentionPeriodHours and LoggingStreamShardCount are no longer needed and have been removed.
• The LoggingStream has been replaced by LoggingFirehoseStream.
• The LoggingBucketSuccessPrefix and LoggingBucketFailurePrefix have been added.

See the LambdaSharp.Core module documentation for more details.

LambdaSharp SDK

IMPORTANT: In preparation to switching LambdaSharp assembly to .NET Core 3.1 and using System.Text.Json as JSON serializer in a future release, it is highly advised to remove all references to Amazon.Lambda.Serialization.Json and Newtonsoft.Json assemblies from all .csproj files. These package are instead inherited via the LambdaSharp assembly. These changes ensure that once LambdaSharp assembly switches its serialization implementation, dependent projects will cease to compile, making it easier to transition to the new JSON serializer. Otherwise, these projects would compile successfully, but fail at runtime, as it is not possible to mix Newtonsoft.Json and System.Text.Json serializations.

Look for the following package references in your .csproj files and remove them.

<PackageReference Include="Amazon.Lambda.Core" Version="1.1.0" />
<PackageReference Include="Amazon.Lambda.Serialization.Json" Version="1.5.0" />
<PackageReference Include="Newtonsoft.Json" Version="12.0.3" />

In addition, Lambda functions no longer need to declare the default serializer with the [assembly: LambdaSerializer(...)] attribute, unless a custom serializer is required. Instead, the serializer is defined by the base class (ALambdaFunction). This change was made to ease the transition to the new System.Text.Json serializer in a future release.

Finally, the SerializeJson(...) and DeserializeJson<T>(...) have been marked as obsolete. Instead, use LambdaSerializer.Serialize(...) and LambdaSerialize.Deserialize<T>(...), respectively.

New LambdaSharp Module Syntax

CloudWatch EventBridge Source

Lambda functions can now subscribe to a CloudWatch event bus. The EventBus notation is straightforward. Multiple event bus subscriptions can be active at the same time.

Sources:
  - EventBus: default
    Pattern:
      source:
        - Sample.Event
      detail-type:
        - MyEvent
      resources:
        - !Sub "lambdasharp:tier:${Deployment::Tier}"

Package Build Command

The Package declaration now supports and optional Build attribute, which specifies a command to run before the zip package is created. This enables creating packages from files that are generated by another project. For example, the output folder when publishing a Blazor WebAssembly application.

- Package: MyBlazorPackage
  Build: dotnet publish -c Release MyBlazorApp
  Files: MyBlazorApp/bin/Release/netstandard2.1/publish/wwwroot/

New Module Variables

New module variables have been introduced that relate to the deployment. These include Deployment::BucketName, Deployment::Tier, and Deployment::TierLowercase. For more details, see the Module Global Variables documentation.

New LambdaSharp CLI Features

The CLI remains mostly unchanged from the previous release.

Misc.

• Updated embedded CloudFormation spec to 14.3.0.
• Enhanced API Gateway V2 WebSocket logging to show error messages.
• Enabled detailed CloudWatch metrics for API Gateway deployments.
• Enhanced lash init to highlight deployment tier name during stack updates.
• Enhanced lash init for LambdaSharp contributors to automatically force build and force publish.
• Enhanced lash nuke to only empty the deployment and logging buckets if they were created by the LambdaSharp.Core module.
• Added --no-ansi option to util delete-orphan-logs, util download-cloudformation-spec, and util create-invoke-methods-schema.
• Added util validate-assembly command.

Fixes

• Fixed an issue were recreating a LambdaSharp.Core deployment from scratch would not update existing deployed modules with the new deployment bucket name.
• Let CloudFormation determine the name for AWS::ApiGateway::Model resources.
• Fixed an issue where the --aws-region command option didn't always work as expected.

New LambdaSharp SDK Features

CloudWatch Metrics

Several Lambda function base classes have been enhanced with custom CloudWatch metrics to augment existing AWS metrics. In addition, the ALambdaFunction base class has new LogMetric(...) methods to emit custom CloudWatch metrics using the embedded metric format.

The MetricSample module shows how to use the new LogMetric(...) methods to emit custom CloudWatch metrics using the embedded metric format.

CloudWatch Events

The ALambdaFunction base class has a new LogEvent(...) method to emit CloudWatch Events to the default event bus on Amazon EventBridge.

The EventSample module shows how to use the new LogEvent(...) method to emit CloudWatch Events to the default event bus on Amazon EventBridge method for sending CloudWatch Events.

Debug Logging

The ALambdaFunction has a new LogDebug(string format, params object[] arguments) method to make debug logging easier. In addition, when debug logging is enabled, the base class logs the request and response streams to CloudWatch logs. See the documentation on Lambda Debugging for more details.

New LambdaSharp Core Services Features

The LambdaSharp.Core module now uses Amazon Kinesis Firehose for ingesting CloudWatch Log streams. During the ingestion process, the logs are converted into queryable JSON documents.

In addition, LambdaSharp.Core now emits operational CloudWatch events to the default event bus, which can be used to observe and track deployed modules.

Finally, the LambdaSharp.Core module emits its own performance metrics to provide quick insight into its operations.

Misc.

Part of this release, LambdaSharp.Core functions were ported to .NET Core 3.1 with null-aware code, and the modules were published with ReadyToRun for shorter cold-start times.

Fixes

• Fixed an issue with processing the Lambda report lines in the CloudWatch logs.

• SDK

  • Added new ALambdaEventFunction<TMessage> base class for handling CloudWatch events.

  • Added constructor to customize serializer settings for LambdaNewtonsoftJsonSerializer.
  • Added null-aware annotations to LambdaSharp assembly.

• Syntax

  • Added Module::RestApi::CorsOrigin pragma override to specify an expression as the CORS Origin header value. The CORS Origin header value is automatically added to all REST API responses.

Features

• CLI
  • Updated embedded CloudFormation spec to 22.0.0.

Fixes

• Modules
  • Fixed a critical issue in LambdaSharp.Core where the CloudWatch Logs analyzer would get overwhelmed at times.

Failed batches can be found in the logging bucket under the logging-failed/ prefix.

(v0.8.1.5) - 2020-12-26

Features

This release introduce support for Blazor WebAssembly apps at the syntax and SDK level. Similar to Lambda functions, Blazor apps have access to the ILambdaSharpLogger to log messages, metrics, and events to CloudWatch. This capability is accomplished by generating a REST API that enables the front-end Blazor app to securely integrate with CloudWatch Logs, Metrics, and EventBridge. By default, Blazor apps are served from an S3 bucket configured as a website. Optionally, the S3 bucket can be configured for integration with CloudFront.
