Run the following commands from your application's root directory: + +```bash +$ mkdir build +$ cd build +$ cmake .. -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=~/lambda-install +$ make +$ make aws-lambda-package-demo +``` +The last command above `make aws-lambda-package-demo` will create a zip file called `demo.zip` in the current directory. + +Now, create an IAM role and the Lambda function via the AWS CLI. + +First create the following trust policy JSON file + +``` +$ cat trust-policy.json +{ + "Version": "2012-10-17", + "Statement": [ + { + "Effect": "Allow", + "Principal": { + "Service": ["lambda.amazonaws.com"] + }, + "Action": "sts:AssumeRole" + } + ] +} + +``` +Then create the IAM role: + +```bash +$ aws iam create-role --role-name lambda-demo --assume-role-policy-document file://trust-policy.json +``` + +Note down the role Arn returned to you after running that command. We'll need it in the next steps: + +Attach the following policy to allow Lambda to write logs in CloudWatch: +```bash +$ aws iam attach-role-policy --role-name lambda-demo --policy-arn arn:aws:iam::aws:policy/service-role/AWSLambdaBasicExecutionRole +``` + +Make sure you attach the appropriate policies and/or permissions for any other AWS services that you plan on using. + +And finally, create the Lambda function: + +``` +$ aws lambda create-function --function-name demo \ +--role \ +--runtime provided --timeout 15 --memory-size 128 \ +--handler demo --zip-file fileb://demo.zip +``` + +And to invoke the function: +```bash +$ aws lambda invoke --function-name demo --payload '{"answer":42}' output.txt +``` + +## Using the C++ SDK for AWS with this runtime +This library is completely independent from the AWS C++ SDK. You should treat the AWS C++ SDK as just another dependency in your application. +See [the examples section](https://github.com/awslabs/aws-lambda-cpp/tree/master/examples/) for a demo utilizing the AWS C++ SDK with this Lambda runtime. + +## Supported Compilers +Any *fully* compliant C++11 compiler targeting GNU/Linux x86-64 should work. Please avoid compiler versions that provide half-baked C++11 support. + +- Use GCC v5.x or above +- Use Clang v3.3 or above + +## Packaging, ABI, GNU C Library, Oh My! +Lambda runs your code on some version of Amazon Linux. It would be a less than ideal customer experience if you are forced to build your application on that platform and that platform only. + +However, the freedom to build on any linux distro brings a challenge. The GNU C Library ABI. There is no guarantee the platform used to build the Lambda function has the same GLIBC version as the one used by AWS Lambda. In fact, you might not even be using GNU's implementation. For example you could build a C++ Lambda function using musl libc. + +To ensure that your application will run correctly on Lambda, we must package the entire C runtime library with your function. +If you choose to build on the same [Amazon Linux version used by lambda](https://docs.aws.amazon.com/lambda/latest/dg/current-supported-versions.html), you can avoid packaging the C runtime in your zip file. +This can be done by passing the `NO_LIBC` flag in CMake as follows: + +```cmake +aws_lambda_package_target(${PROJECT_NAME} NO_LIBC) +``` +### Common Pitfalls with Packaging + +* Any library dependency your Lambda function has that is dynamically loaded via `dlopen` will NOT be automatically packaged. You **must** add those dependencies manually to the zip file. +This applies to any configuration or resource files that your code depends on. + +* If you are making HTTP calls over TLS (https), keep in mind that the CA bundle location is different between distros. +For example, if you are using the AWS C++ SDK, it's best to set the following configuration options: + +```cpp +Aws::Client::ClientConfiguration config; +config.caFile = "/etc/pki/tls/certs/ca-bundle.crt"; +``` +If you are not using the AWS C++ SDK, but happen to be using libcurl directly, you can set the CA bundle location by doing: +```c +curl_easy_setopt(curl_handle, CURLOPT_CAINFO, "/etc/pki/tls/certs/ca-bundle.crt"); +``` + +## FAQ & Troubleshooting +1. **Why is the zip file so large? what are all those files?** + Typically, the zip file is large because we have to package the entire C standard library. + You can reduce the size by doing some or all of the following: + - Ensure you're building in release mode `-DCMAKE_BUILD_TYPE=Release` + - If possible, build your function using musl libc, it's tiny. The easiest way to do this, assuming your code is portable, is to build on Alpine linux, which uses musl libc by default. +1. **How to upload a zip file that's bigger than 50MB via the CLI?** + Upload your zip file to S3 first: + ```bash + $ aws s3 cp demo.zip s3://mys3bucket/demo.zip + ``` + NOTE: you must use the same region for your S3 bucket as the lambda. + + Then you can create the Lambda function this way: + + ```bash + $ aws lambda create-function --function-name demo \ + --role \ + --runtime provided --timeout 15 --memory-size 128 \ + --handler demo + --code "S3Bucket=mys3bucket,S3Key=demo.zip" + ``` +1. **My code is crashing, how can I debug it?** + + - Starting with [v0.2.0](https://github.com/awslabs/aws-lambda-cpp/releases/tag/v0.2.0) you should see a stack-trace of the crash site in the logs (which are typically stored in CloudWatch). + - To get a more detailed stack-trace with source-code information such as line numbers, file names, etc. you need to install one of the following packages: + - On Debian-based systems - `sudo apt install libdw-dev` or `sudo apt install binutils-dev` + - On RHEL based systems - `sudo yum install elfutils-devel` or `sudo yum install binutils-devel` + If you have either of those packages installed, CMake will detect them and automatically link to them.

More info in the [docs](https://docs.aws.amazon.com/lambda/latest/dg/java-handler.html). + +When you want to test your Lambda function and your handleRequest method, you cannot simply use JSON events files +as some of the event fields may not be deserialized correctly. + +For example, an SQS JSON event contains a list of "Records", while the [`SQSEvent`](https://github.com/aws/aws-lambda-java-libs/blob/master/aws-lambda-java-events/src/main/java/com/amazonaws/services/lambda/runtime/events/SQSEvent.java) use "records" with a lowercase. +You can choose to modify the JSON input but it can be tedious and you generally want to keep the JSON event as you get it +in the doc, the Lambda console or in your logs. + +Now you can use the [aws-lambda-java-serialization](https://github.com/aws/aws-lambda-java-libs/tree/master/aws-lambda-java-serialization) module to deserialize events.

                                AWS Lambda Profiler Extension for Java

                                + +The Lambda profiler extension allows you to profile your Java functions invoke by invoke, with high fidelity, and no +code changes. It uses the [async-profiler](https://github.com/async-profiler/async-profiler) project to produce +profiling data and automatically uploads the data as HTML flame graphs to S3. + +

                                + A flame graph of a Java Lambda function +

                                + +## Current status +**This is an alpha release and not yet ready for production use.** We're especially interested in early feedback on usability, features, performance, and compatibility. Please send feedback by opening a [GitHub issue](https://github.com/aws/aws-lambda-java-libs/issues/new). + +The profiler has been tested with Lambda managed runtimes for Java 17 and Java 21. + +## How to use the Lambda Profiler + +To use the profiler you need to + +1. Build the extension in this repo +2. Deploy it as a Lambda Layer and attach the layer to your function +3. Create an S3 bucket for the results, or reuse an existing one +4. Give your function permission to write to the bucket +5. Configure the required environment variables. + +The above assumes you're using the ZIP deployment method with managed runtimes. If you deploy your functions as container images instead, you will need to include the profiler in your Dockerfile at `/opt/extensions/` rather than using a Lambda layer. + +### Quick Start + +The following [Quick Start](#quick-start) gives AWS CLI commands you can run to get started (MacOS/Linux). There are also [examples](examples) using infrastructure as code for you to refer to. + +1. Clone the repo + + ```bash + git clone https://github.com/aws/aws-lambda-java-libs + ``` + +2. Build the extension + + ```bash + cd aws-lambda-java-libs/experimental/aws-lambda-java-profiler/extension + ./build_layer.sh + ``` + +3. Run the `update-function.sh` script which will create a new S3 bucket, Lambda layer and all the configuration required. + + ```bash + cd .. + ./update-function.sh YOUR_FUNCTION_NAME + ``` + +4. Invoke your function and review the flame graph in S3 using your browser. + +### Configuration + +#### Required Environment Variables + +| Name | Value | +|-----------------------------------------|-----------------------------------------------------------------------------------------------| +| AWS_LAMBDA_PROFILER_RESULTS_BUCKET_NAME | Your unique bucket name | +| JAVA_TOOL_OPTIONS | -XX:+UnlockDiagnosticVMOptions -XX:+DebugNonSafepoints -javaagent:/opt/profiler-extension.jar | + +#### Optional Environment Variables + +| Name | Default Value | Options | +|------------------------------------------|-----------------------------------------------------------|--------------------------------| +| AWS_LAMBDA_PROFILER_START_COMMAND | start,event=wall,interval=1us | | +| AWS_LAMBDA_PROFILER_STOP_COMMAND | stop,file=%s,include=*AWSLambda.main,include=start_thread | file=%s is required | +| AWS_LAMBDA_PROFILER_DEBUG | false | true - to enable debug logging | +| AWS_LAMBDA_PROFILER_COMMUNICATION_PORT | 1234 | a valid port number | + +### How does it work? + +In `/src` is the code for a Java agent. It's entry point `AgentEntry.premain()` is executed as the runtime starts up. +The environment variable `JAVA_TOOL_OPTIONS` is used to specify which `.jar` file the agent is in. The `MANIFEST.MF` file is used to specify the pre-main class. + +When the agent is constructed, it starts the profiler and registers itself as a Lambda extension for `INVOKE` request. + +A new thread is created to handle calling `/next` and uploading the results of the profiler to S3. The bucket to upload +the result to is configurable using an environment variable. + +### Custom Parameters for the Profiler + +Users can configure the profiler output by setting environment variables. + +``` +# Example: Output as JFR format instead of HTML +AWS_LAMBDA_PROFILER_START_COMMAND="start,event=wall,interval=1us,file=/tmp/profile.jfr" +AWS_LAMBDA_PROFILER_STOP_COMMAND="stop,file=%s" +``` + +Defaults are the following: + +``` +AWS_LAMBDA_PROFILER_START_COMMAND="start,event=wall,interval=1us" +AWS_LAMBDA_PROFILER_STOP_COMMAND="stop,file=%s,include=*AWSLambda.main,include=start_thread" +``` + +See [async-profiler's ProfilerOptions](https://github.com/async-profiler/async-profiler/blob/master/docs/ProfilerOptions.md) for all available profiler parameters. + +### Troubleshooting + +- Ensure the Lambda function execution role has the necessary permissions to write to the S3 bucket. +- Verify that the environment variables are set correctly in your Lambda function configuration. +- Check CloudWatch logs for any error messages from the extension. +- The profiler extension uses dependencies such as `com.amazonaws:aws-lambda-java-core`, `com.amazonaws:aws-lambda-java-events` and `software.amazon.awssdk:s3`. If you're using the same dependencies in your Lambda function, make sure that the versions match those used by the extension as mismatched versions can lead to compatibility issues. + +## Contributing + +Contributions to improve the Java profiler extension are welcome. Please see [CONTRIBUTING.md](../../CONTRIBUTING.md) for more information on how to report bugs or submit pull requests. + +Issues or contributions to the [async-profiler](https://github.com/async-profiler/async-profiler) itself should be submitted to that project. + +### Security + +If you discover a potential security issue in this project we ask that you notify AWS Security via our [vulnerability reporting page](http://aws.amazon.com/security/vulnerability-reporting/).
