From 331cba42aae3addb1f59aea094164064cf2b3543 Mon Sep 17 00:00:00 2001 From: "russell@unturf.com" Date: Thu, 15 Jan 2026 17:32:24 -0500 Subject: [PATCH] feat: Complete 6 additional SDK implementations with fixes and examples Go Async SDK (clients/go/async/): - Fixed case-sensitive language detection bug (.R for R language) - Created go.mod for module management - Added comprehensive test suite - Created 3 examples with expected output comments - Added README with full documentation Java Sync SDK (clients/java/sync/): - RENAMED: Unsandbox.java -> Un.java (matches naming convention) - Updated class name from Unsandbox to Un - Created pom.xml for Maven build - Added 6 examples (simple + SDK client versions) - Created test suite with JUnit 5 - Added README with API documentation JavaScript Async SDK (clients/javascript/async/): - Fixed unused import - Created package.json with ES module support - Added 5 examples covering all async patterns - Created 71 tests (all passing) - Added comprehensive README PHP Sync SDK (clients/php/sync/): - RENAMED: Unsandbox.php -> un.php (matches naming convention) - Created composer.json with PSR-4 autoloading - Created phpunit.xml for testing - Added 4 examples with expected output comments - Created 54 tests across 4 test files - Added README with full documentation Ruby Sync SDK (clients/ruby/sync/): - Created Gemfile and un.gemspec - Created Rakefile with test task - Updated examples to actually use the SDK - Added 4 examples (hello_world, async_job, language_detection, snapshots) - Created comprehensive test suite with 30+ tests - Added README with documentation Rust Sync SDK (clients/rust/sync/): - Updated Cargo.toml with example declarations - Created 4 examples (hello_world, fibonacci, multi_language, async_polling) - Added comprehensive README with API reference - All dependencies verified correct All SDKs verified: - HMAC-SHA256 authentication implemented - 4-tier credential system (args > env > ~/.unsandbox > ./accounts.csv) - Expected output comments for pipeline validation - Proper error handling - Language detection support --- clients/go/async/README.md | 273 ++

"job_xyz789", + status: "failed", + stdout: "partial output", + stderr: "Error message\n", + exit_code: 1, + language: "python", + duration_ms: 567 +} +``` + +### Job Statuses + +- `pending` - Waiting to execute +- `running` - Currently executing +- `completed` - Finished successfully +- `failed` - Execution error +- `timeout` - Exceeded time limit +- `cancelled` - Cancelled by user + +## Examples + +See the `examples/` directory for complete working examples: + +- `hello_world.js` - Basic async execution +- `fibonacci.js` - Concurrent fibonacci calculations +- `concurrent_execution.js` - Running multiple jobs concurrently +- `async_job_polling.js` - Fire-and-forget job management +- `language_detection.js` - Automatic language detection + +## Testing + +Run the test suite: + +```bash

Run with coverage +npm run test:coverage +``` + +### Test Files + +- `hmac_signing.test.js` - HMAC request signing +- `language_detection.test.js` - Language detection +- `credentials.test.js` - Credential resolution system +- `async_operations.test.js` - Async API operations + +## Supported Languages + +**50+ Languages** including: + +**Interpreted:** Python, JavaScript, Ruby, PHP, Perl, Bash, Lua, R, Julia, Scheme, Tcl, Raku, Clojure, Groovy, Crystal, Dart, Elixir, Erlang, Haskell, OCaml, Common Lisp, Forth, Prolog, and more + +**Compiled:** C, C++, Go, Rust, Java, Kotlin, C#, D, Nim, Zig, V, Pascal, Fortran, COBOL, Objective-C, and more + +**Specialized:** TypeScript, F#, Odin + +Use `detectLanguage()` for automatic detection or get full list with `await getLanguages()`. + +## Error Handling + +```javascript +import { executeCode, CredentialsError, TimeoutError } from './src/un_async.js'; + +try { + const result = await executeCode('python', "print('hello')"); +} catch (e) { + if (e instanceof CredentialsError) { + console.log(`Credentials error: ${e.message}`); + } else if (e instanceof TimeoutError) { + console.log(`Timeout error: ${e.message}`); + } else { + console.log(`Unexpected error: ${e.message}`); + } +} +``` + +## Performance Tips + +1. **Use Concurrent Execution** for multiple independent jobs: + ```javascript + const results = await Promise.all([ + executeCode('python', '...'), + executeCode('go', '...'), + executeCode('rust', '...'), + ]); + ``` + +2. **Use Exponential Backoff** with `waitForJob()` instead of polling manually + +3. **Cache Languages** - `getLanguages()` caches results for 1 hour + +## Differences from Sync SDK + +This async SDK uses ES Modules with native fetch, while the sync SDK uses CommonJS with https module: + +**Sync SDK:** +```javascript +const { executeCode } = require('./un.js'); +executeCode('python', "print('hello')").then(console.log); +``` + +**Async SDK:** +```javascript +import { executeCode } from './un_async.js'; +const result = await executeCode('python', "print('hello')"); +``` + +Key differences: +- ES Modules (`import`/`export`) instead of CommonJS (`require`) +- Uses native `fetch()` (Node.js 18+) instead of `https` module +- Same credential system and HMAC signing +- Same API functions with same signatures + +## Requirements + +- Node.js 18.0.0 or later (for native fetch support) + +## License + +Public Domain - NO LICENSE, NO WARRANTY + +## Support + +Visit [unsandbox.com](https://unsandbox.com) for API documentation and support. diff --git
