Upgrade Language Versions and Add New Language Support via Alpine Base Docker Image #175

Abhinav-Prajapati · 2025-06-18T04:51:17Z

Summary

Upgraded core language versions (Node.js, Python, Java, Ruby, GCC) to newer stable releases.
Added support for additional languages: Go, PHP, TypeScript (TSC), C# (Mono), Kotlin.
Note: Swift is not supported due to Alpine’s incompatibility with glibc.

Key Changes

Introduced a new Dockerfile.alpine instead of modifying the main Dockerfile to:
- Simplify dependency management via Alpine’s apk.
- Avoid cluttering the main Dockerfile due to major changes in language setup logic.
- Ensure quicker builds using precompiled packages.

Why This Change?

Feature	Manual Setup	Alpine-based Setup
Latest Versions	Manually tracked	Pulled automatically
Dependency Handling	High maintenance	Clean and easy via apk
Build Speed	Slower	Faster
Complexity	High	Low
Package Conflicts	Possible	Minimal with Alpine repos

Testing

Updated tests to validate new languages: Go, PHP, TypeScript, C#, Kotlin.

Summary of Changes

Hello @Abhinav-Prajapati, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request represents a significant enhancement to our code execution environment. My primary goal was to broaden the spectrum of supported programming languages and ensure that our existing language runtimes are current. This was achieved by migrating the language setup to a new Alpine-based Docker image, which offers substantial benefits in terms of build efficiency and package management. Additionally, I've integrated comprehensive memory usage tracking and validation into the execution and testing pipeline, providing better insights into resource consumption.

Highlights

New Language Support: I've added support for several new programming languages: Go, PHP, TypeScript (TSC), C# (via Mono), and Kotlin. This significantly expands the range of executable code types the system can handle.
Language Version Upgrades: Core language versions for Node.js, Python, Java, Ruby, and GCC have been upgraded to their latest stable releases, ensuring the environment is up-to-date.
Alpine-based Docker Environment: A new Dockerfile.alpine has been introduced to build a lightweight, Alpine Linux-based Docker image. This approach simplifies dependency management using apk, speeds up build times, and keeps the main Dockerfile clean.
Memory Usage Monitoring & Testing: The execution service now includes robust memory usage monitoring for all languages, capturing and reporting the actual memory consumed by executed code. Corresponding test cases have been updated to validate memory limits with a defined tolerance.

Code Review

This pull request significantly expands language support and updates existing versions by introducing a new Alpine-based Docker image. The changes are generally well-structured, and the addition of memory usage reporting and testing is a valuable improvement.

Key areas for attention within Dockerfile.alplne include a syntax error in a RUN command that will break the build, the unconventional use of /usr/bin/ for application code and node_modules, and a leftover PATH entry for Swift (which is noted as unsupported). Addressing these will improve the Docker image's correctness, maintainability, and adherence to best practices.

Additionally, enhancing the new language test cases in tests/data/testJson.js to include approxMemoryUses would provide more robust validation for these additions.

Dockerfile.alplne

+    adduser -S -D -u 2000 -s /sbin/nologin -h /tmp -G runner runner
+
+# Set up environment variables for all languages
+ENV PATH="/opt/node/bin:/opt/swift/usr/bin:$PATH"


The ENV PATH includes /opt/swift/usr/bin. However, the PR description explicitly states that Swift is not supported due to Alpine's incompatibility with glibc. This path entry appears to be a leftover or mistake and should be removed to avoid confusion and keep the environment clean.

ENV PATH="/opt/node/bin:$PATH"

tests/data/testJson.js

+        name: "Go: Basic Hello World",
+        reqObject: {
+            language: "go",
+            script: `
+package main
+import "fmt"
+
+func main() {
+    fmt.Println("Language: Go")
+}`
+        },
+        expectedResponse: {
+            val: "Language: Go\n",
+            status: 200,
+            error: 0
+        }


The new test case for Go does not include the approxMemoryUses field in expectedResponse. While basic execution is tested, adding expected memory usage would make these tests consistent with the memory validation strategy applied to other languages and provide more comprehensive testing for the new additions.

tests/data/testJson.js

+        name: "PHP: Basic Hello World",
+        reqObject: {
+            language: "php",
+            script: `
+<?php echo "Language: PHP";?>`
+        },
+        expectedResponse: {
+            val: "\nLanguage: PHP",
+            status: 200,
+            error: 0
+        }


This new PHP test case is missing the approxMemoryUses field in expectedResponse. Including this would enhance test coverage by validating memory usage, aligning with the testing improvements made for other languages.

tests/data/testJson.js

+        name: "TypeScript: Basic Hello World",
+        reqObject: {
+            language: "typescript",
+            script: `
+function main(): void {
+    console.log("Language: TypeScript");
+}
+
+main();`
+        },
+        expectedResponse: {
+            val: "Language: TypeScript\n",
+            status: 200,
+            error: 0
+        }


This new TypeScript test case lacks the approxMemoryUses field in expectedResponse. To ensure consistent and comprehensive testing across all supported languages, especially with the new memory validation feature, it's recommended to add expected memory usage here.

tests/data/testJson.js

+        name: "C#: Basic Hello World",
+        reqObject: {
+            language: "csharp",
+            script: `
+using System;
+class Solution {
+    static void Main(string[] args) {
+        Console.WriteLine("Language: C#");
+    }
+}`
+        },
+        expectedResponse: {
+            val: "Language: C#\n",
+            status: 200,
+            error: 0
+        }


The new C# test case is missing the approxMemoryUses field in expectedResponse. Adding this would improve the test's comprehensiveness by including memory usage validation, consistent with how other languages are being tested.

gemini-code-assist · 2025-06-18T04:53:23Z

tests/data/testJson.js

+        name: "Kotlin: Basic Hello World",
+        reqObject: {
+            language: "kotlin",
+            script: `
+fun main() {
+  println("Language: Kotlin")
+}`
+        },
+        expectedResponse: {
+            val: "Language: Kotlin\n",
+            status: 200,
+            error: 0
+        }


For consistency and to leverage the new memory validation capabilities, this new Kotlin test case should also include an approxMemoryUses field in its expectedResponse. This will help ensure that Kotlin programs run within expected memory footprints.
