benchmarks/600.java/601.hello-world/java/src/main/java/faas/App.java (3)
1-1: Consider using a more specific package name.The current package name
faasis concise but might be too generic. To provide better context and avoid potential conflicts, consider using a more specific package name that reflects the project structure or purpose, such ascom.spcl.serverlessbenchmarks.java.helloworld.
3-3: Consider using a more descriptive class name.While
Appis a common name for main application classes, it might be too generic for a benchmark-specific application. Consider using a more descriptive name that reflects the purpose of this benchmark, such asHelloWorldBenchmarkorJavaFunctionBenchmark.
1-7: Summary: Good start, but room for improvementOverall, this file provides a basic starting point for Java benchmarks in the serverless framework. However, there are several areas where it could be improved to better serve its purpose:
- The package name could be more specific.
- The class name could be more descriptive.
- The main method could include more benchmark-specific functionality.
These changes would make the code more robust and better suited for benchmarking purposes.
Would you like assistance in implementing these suggestions or in developing more advanced benchmarking features for this Java function?
dockerfiles/openwhisk/java/Dockerfile.function (3)
1-3: LGTM with a suggestion for optimizationThe base image setup looks good. Using a build argument for the base image provides flexibility for different environments or versions.
However, consider optimizing the
COPYcommand to only include necessary files for the function, rather than copying the entire context. This can reduce the image size and build time.You could update the
COPYcommand to be more specific, for example:COPY pom.xml /function/ COPY src /function/srcThis assumes your Java source files are in a
srcdirectory. Adjust the paths as needed for your project structure.
7-8: LGTM with a suggestion for improved readabilityThe Maven build process is well-implemented. The conditional check for
pom.xmlis a good practice to avoid errors if the file is missing.To improve readability, consider breaking the long RUN command into multiple lines:
RUN if [ -f ./pom.xml ]; then \ mvn clean install; \ else \ echo "pom.xml not found, aborting build." && exit 1; \ fiThis multi-line format is easier to read and maintain, especially if you need to add more complex logic in the future.
1-8: Overall, the Dockerfile is well-structured with room for minor improvementsThe Dockerfile successfully sets up a build environment for Java functions in OpenWhisk. It uses a flexible base image, installs the necessary build tools (Maven), and attempts to build the project conditionally.
A few suggestions for improvement:
- Optimize the COPY command to only include necessary files.
- Clean up the apt cache after installing Maven to reduce image size.
- Improve readability of the conditional Maven build command.
Also, note that this Dockerfile doesn't specify an ENTRYPOINT or CMD. This might be intentional if it's meant to be extended, but ensure this aligns with your intended use in the OpenWhisk environment.
Consider documenting the expected usage of this Dockerfile, especially if it's intended to be extended or used as part of a multi-stage build process. This will help other developers understand its purpose and how to properly use or modify it.
benchmarks/600.java/601.hello-world/java/pom.xml (2)
8-12: Consider revising the groupId and artifactId.While the version and packaging are appropriate, there are some concerns with the project coordinates:
- The groupId "faas" is unusually short and doesn't follow the reverse domain name convention (e.g., com.company.project).
- The artifactId "601.hello-world" includes a number prefix, which is unconventional and may cause issues with some tools.
Consider revising these to more standard formats:
- groupId: e.g., "com.spcl.serverlessbenchmarks"
- artifactId: e.g., "hello-world-java"
1-38: Summary: Basic Maven configuration in place, with room for improvements.The pom.xml file provides a functional Maven configuration for a Java project. However, there are several areas where it could be improved to align better with best practices and provide a more robust setup:
- Revise the groupId and artifactId to follow standard conventions.
- Consider updating to a more recent Java version.
- Update the maven-jar-plugin to the latest version.
- Review the main class package name for better alignment with Java conventions.
- Consider adding necessary dependencies if the project requires any external libraries.
These changes will enhance the project structure, maintainability, and potentially performance.
benchmarks/wrappers/openwhisk/java/Main.java (3)
1-9: Remove unused importThe
Gsonclass is imported but never used in the code. Consider removing this unused import to keep the code clean.Apply this diff to remove the unused import:
-import com.google.gson.JsonObject;
10-17: Remove commented-out code and unused variable
The commented-out logger setup is not being used. If logging is not required, remove these comments to improve code readability.
The
Gsoninstance is created but never used in the code. Remove it to avoid confusion and potential performance impact.Apply this diff to clean up the code:
- // Logger logger = Logger.getLogger(FunctionHandler.class.getName()); - // logger.setLevel(Level.INFO); - - Gson gson = new Gson(); App function = new App();
1-55: Overall assessment and remaining concernsThe
Mainclass provides a good structure for handling serverless function invocations, including timing the execution and detecting cold starts. However, there are a few areas that could be improved:
- Error handling: Consider adding more robust error handling throughout the class, especially for the
App.handlercall.- Cold start detection: The current method using file I/O might not be reliable in all serverless environments. Consider using a more robust method.
- Code cleanliness: Remove unused imports and commented-out code to improve readability.
- Performance: Ensure that the
Appinstance is created efficiently, possibly as a static field if it's thread-safe, to avoid unnecessary object creation on each invocation.To improve the overall design:
- Consider extracting the cold start detection logic into a separate method or class for better modularity.
- If possible, make the
Appclass conform to a specific interface that defines thehandlermethod, allowing for easier testing and potential dependency injection.- Consider adding logging throughout the class to aid in debugging and monitoring in a production environment.
These changes will make the code more robust, maintainable, and performant in a serverless environment.

247-263: Java configuration for OpenWhisk looks good, with some suggestions for improvement.The new Java configuration for OpenWhisk is well-structured and consistent with other language configurations. It aligns with the PR objective of adding Java support. Here are some observations and suggestions:
- The base image, deployment files, and Minio package inclusion are appropriate for a Java application in OpenWhisk.
- Consider adding support for newer Java versions (e.g., Java 11, 17) to provide more options for users.
- Verify if Minio version 8.5.9 is the latest stable version compatible with Java 8. If not, consider updating to the latest compatible version.
- Evaluate if any additional Java-specific packages or configurations are needed for optimal performance in OpenWhisk.
Would you like assistance in expanding the Java version support or verifying the Minio version compatibility?
sebs/faas/function.py (2)
303-303: LGTM: Java support added to Runtime.deserializeThe addition of Java to the languages dictionary in Runtime.deserialize is correct and consistent with the existing structure.
Consider refactoring this method to use a more dynamic approach for language mapping. This could make it easier to add new languages in the future without modifying this method. For example:
@staticmethod def deserialize(config: dict) -> Runtime: try: language = Language[config["language"].upper()] except KeyError: raise ValueError(f"Unsupported language: {config['language']}") return Runtime(language=language, version=config["version"])This approach would automatically work for any language added to the Language enum without requiring changes to this method.
Java support is not fully integrated across the codebase
Several parts of the project still have hardcoded language checks limited to Python and Node.js. To ensure consistent Java support, please update the following files to include Java where applicable:

222-222: LGTM: Addition of Java configuration fileThe inclusion of "Main.java" in the
CONFIG_FILESdictionary for the Java language is correct and necessary for proper packaging of Java benchmarks. This change ensures that the main Java file is included in the zip archive created for deployment, similar to how Python and Node.js files are handled.For consistency with the other entries, consider using a list even for a single file:
- "java": ["Main.java"], + "java": ["Main.java"],This change doesn't affect functionality but maintains consistency with the Python and Node.js entries, which use lists.

66-66: Summary: Java support added to CLIThe change successfully adds Java as a language option in the CLI, which is a crucial first step in supporting Java benchmarks in the SeBS framework. This modification aligns well with the PR objectives.
However, it's important to note that this change only affects the CLI interface. To ensure full Java support, other parts of the system (such as benchmark configurations, deployment logic, and result processing) may need to be updated as well. These updates might be present in other files or could be part of future PRs.
Consider creating a checklist or documentation for adding new language support to ensure all necessary components are updated consistently across the system.

🛠️ Refactor suggestion
Optimize Maven installation to reduce image size
The Maven installation step is correct, but it can be optimized to reduce the final image size.
Consider updating the Maven installation command to clean up the apt cache:
RUN apt-get update && \
apt-get install -y maven && \
apt-get clean && \
rm -rf /var/lib/apt/lists/*This will remove unnecessary package files after installation, resulting in a smaller image size.

🛠️ Refactor suggestion
Consider updating to a more recent Java version.
The project is currently configured to use Java 8 (1.8) for both source and target compatibility. While Java 8 is still widely used, it's becoming outdated. Consider updating to a more recent LTS version like Java 11 or 17 to benefit from performance improvements and newer language features.
To update, you would change these lines:
<maven.compiler.source>11</maven.compiler.source>
<maven.compiler.target>11</maven.compiler.target>Or for Java 17:

Review security settings and sensitive information handling
The deployment configuration for OpenWhisk is comprehensive. However, there are some security considerations to address:
- The
wskBypassSecurityis set to "true". This could pose a security risk if used in a production environment. - Sensitive information fields (Docker registry credentials, storage access keys) are left empty. Ensure you have a secure method to populate these fields in different environments.
Consider the following improvements:
- Set
wskBypassSecuritytofalseunless absolutely necessary for testing purposes. - Implement a secure method to inject sensitive information (e.g., environment variables, secrets management system) rather than hardcoding them in the configuration file.
- Add a comment in the file to indicate how sensitive information should be handled.
Example:
"wskBypassSecurity": false,
// ... other fields ...
"docker_registry": {
"registry": "", // Set via DOCKER_REGISTRY env var
"username": "", // Set via DOCKER_USERNAME env var
"password": "" // Set via DOCKER_PASSWORD env var

Incorrect dependency handling: Appending to 'requirements.txt' in Java project
The add_deployment_package_java method appends Java packages to requirements.txt, which is used for Python dependencies. In Java Maven projects, dependencies should be managed through the pom.xml file, not requirements.txt.
Consider modifying the method to add the deployment packages to the pom.xml file by updating the ``` section accordingly.

Improve indentation, comments, and error handling in the Java source copying logic
The indentation of comments is inconsistent, which can affect readability. Additionally, it's advisable to check if the source directory exists before attempting to copy it, to avoid potential exceptions if the directory doesn't exist.
Apply this diff to correct the issues:
# copy src folder of java (Java benchmarks are Maven projects and need directories)
if self.language_name == "java":
output_src_dir = os.path.join(output_dir, "src")
# If src dir in output exists, remove the directory and all its contents
if os.path.exists(output_src_dir):
shutil.rmtree(output_src_dir)
src_dir = os.path.join(path, "src")
# Check if src directory exists in the benchmark path
+ if os.path.exists(src_dir):
shutil.copytree(src_dir, output_src_dir)📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

@mahlashrifi This does not look correct - requirements.txt should only be used for Python projects. In Python, we add packages needed for specific functions to this file such that pip installs them.
Shouldn't we use something else for Java?

Dockerfile is very good :-) But we should also be able to deploy the code as zip package; particularly for cloud platforms that do not support containers (Azure, GCP). Can you add that or should I take a look into that?

4-5: Remove unused imports to keep the code clean.Imports
util.SessionBlobandutil.ShaSecurityProviderare not referenced anywhere in this class. Unused imports can cause confusion and bloat the code.-import util.SessionBlob; -import util.ShaSecurityProvider;
10-10: Remove or replace commented-out import.The commented-out
import jakarta.ws.rs.core.Response;line appears to be a leftover and may not be needed. Consider removing it if not used.-//import jakarta.ws.rs.core.Response;
58-58: Embed the result JSON object directly.Currently,
jsonResult.addProperty("result", result.toString())inserts the stringified JSON. Ifresultis already aJsonObject, consider adding it as a nested object:-jsonResult.addProperty("result", result.toString()); +jsonResult.add("result", result);This preserves the original JSON structure for downstream consumers.

25-25: Add error handling for App.handler call.This replicates a past recommendation: wrapping the
App.handler(args)call in a try-catch block will protect against unhandled exceptions that could crash the application. You could provide a JSON response indicating an error if it fails. For example:-JsonObject result = function.handler(args); +JsonObject result; +try { + result = function.handler(args); +} catch (Exception e) { + result = new JsonObject(); + result.addProperty("error", "An error occurred while processing the request: " + e.getMessage()); +}
34-44: Use a safer and more reliable cold start detection mechanism.As discussed in a previous review, using
/cold_runcan fail in certain environments where/may not be writable. A common approach is to use a static boolean flag or create the file in/tmp. For instance:private static boolean firstExecution = true; boolean isCold = firstExecution; if (firstExecution) { firstExecution = false; }Or:
-String fileName = "/cold_run"; +String fileName = "/tmp/cold_run";sebs/benchmark.py (1)
328-337: Avoid adding Java dependencies to requirements.txt.This code appends Java packages to a Python-specific
requirements.txt. Instead, Java dependencies should be managed inpom.xml:- with open(os.path.join(output_dir, "requirements.txt"), "a") as out: - for package in packages: - out.write(package) + # For Java, update <dependencies> in pom.xml, not requirements.txt. + # e.g.,: + # <dependency> + # <groupId>GROUP_ID</groupId> + # <artifactId>ARTIFACT_ID</artifactId> + # <version>VERSION</version> + # </dependency>

1-5: Configuration looks good for a Java benchmark.The configuration specifies appropriate parameters for a Java serverless function benchmark with a reasonable timeout of 60 seconds and a standard memory allocation of 256 MB.
benchmarks/600.java/601.hello-world/input.py (1)
1-5: Implementation is appropriate for a simple hello-world benchmark.Both functions return empty/zero values, which is appropriate for this type of benchmark that doesn't require any specific input data generation. The functions implement the expected interface for the benchmark framework but correctly indicate that no input preparation is needed.
benchmarks/600.java/601.hello-world/java/src/main/java/faas/App.java (1)
1-11: Basic OpenWhisk Java action implementation looks good.The class correctly implements a simple OpenWhisk Java action with proper JSON handling using Gson. The implementation follows the expected patterns for a serverless function in this environment.
Refine the output message and consider adding benchmark-specific functionality.
For benchmarking purposes, consider adding more functionality to this method such as:
- Parameters to control iterations
- Timing code to measure execution performance
- Computation to test different performance aspects
benchmarks/600.java/601.hello-world/java/pom.xml (1)
1-45: Maven configuration is appropriate for a Java serverless function.The POM file correctly configures the Maven project with:
- Project coordinates matching the implementation
- Required Gson dependency for JSON processing
- Maven Shade plugin to create an uber JAR with dependencies
Consider updating to a more recent Java version.
The project is currently configured to use Java 8. While Java 8 is still used, consider updating to a more recent LTS version like Java 11 or 17 to benefit from performance improvements and newer language features.

263-271: Improve indentation, comments, and error handling in the Java source copying logicThe indentation of comments is inconsistent, which can affect readability. Additionally, it's advisable to check if the source directory exists before attempting to copy it, to avoid potential exceptions if the directory doesn't exist.
Apply this diff to correct the issues:
# copy src folder of java (java benchmarks are maven project and need directories) if self.language_name == Language.JAVA: output_src_dir = os.path.join(output_dir, "src") if os.path.exists(output_src_dir): # If src dir in output exist, remove the directory and all its contents shutil.rmtree(output_src_dir) #To have contents of src directory in the direcory named src located in output - shutil.copytree(os.path.join(path, "src"), output_src_dir) + src_dir = os.path.join(path, "src") + if os.path.exists(src_dir): + shutil.copytree(src_dir, output_src_dir) + else: + print(f"Warning: Source directory {src_dir} does not exist")
328-337: Incorrect dependency handling: Appending to 'requirements.txt' in Java projectThe
add_deployment_package_javamethod appends Java packages torequirements.txt, which is used for Python dependencies. In Java Maven projects, dependencies should be managed through thepom.xmlfile, notrequirements.txt.Consider modifying the method to add the deployment packages to the

369-370: Use Language enum value consistentlyYou're using the Language enum for Java language check, which is good practice. However, make sure this is used consistently throughout the code.
This part correctly references the Language enum which improves code maintainability.

330-339:⚠️ Potential issueIncorrect dependency handling: Appending to 'requirements.txt' in Java project.
The
add_deployment_package_javamethod appends Java packages torequirements.txt, which is used for Python dependencies. In Java Maven projects, dependencies should be managed through thepom.xmlfile, notrequirements.txt.Consider modifying the method to add the deployment packages to the
pom.xmlfile by updating the<dependencies>section. Here's a potential solution:def add_deployment_package_java(self, output_dir): - # append to the end of requirements file + # append to the pom.xml file's dependencies section packages = self._system_config.deployment_packages( self._deployment_name, self.language_name ) if len(packages): - with open(os.path.join(output_dir, "requirements.txt"), "a") as out: - for package in packages: - out.write(package) + pom_path = os.path.join(output_dir, "pom.xml") + if os.path.exists(pom_path): + # Parse the pom.xml file + import xml.etree.ElementTree as ET + tree = ET.parse(pom_path) + root = tree.getroot() + + # Find the dependencies section or create it + ns = {'': 'http://maven.apache.org/POM/4.0.0'} + dependencies = root.find('.//dependencies', ns) + if dependencies is None: + dependencies = ET.SubElement(root, 'dependencies') + + # Add each package as a dependency + for artifact_id, version in packages.items(): + dependency = ET.SubElement(dependencies, 'dependency') + group_id = ET.SubElement(dependency, 'groupId') + group_id.text = 'com.example' # This should be replaced with actual group IDs + artifact = ET.SubElement(dependency, 'artifactId') + artifact.text = artifact_id + ver = ET.SubElement(dependency, 'version') + ver.text = version + + # Write back to the pom.xml file + tree.write(pom_path, encoding='utf-8', xml_declaration=True)Alternatively, you might need to discuss with the team about how Java dependencies should be handled in this framework.
265-274:⚠️ Potential issueFix indentation and add error handling in Java source copying.
The indentation is inconsistent and there's no check if the source directory exists before copying it, which could lead to exceptions.

Improve Java build process handling.
The method doesn't check if src_dir exists before trying to move files into it, which could lead to errors. Also, you should capture and log more specific errors that might occur during the Maven build.
