# HumanEval Rust: Evaluation Harness for SigilDERG Ecosystem

A specialized evaluation harness for assessing Rust code generation capabilities of language models, designed as a core component of the [SigilDERG ecosystem](https://github.com/Superuser666-Sigil) for Rust-focused AI development.

> 📖 **Ecosystem Architecture**: For a comprehensive overview of how this project integrates with [SigilDERG-Data_Production](https://github.com/Superuser666-Sigil/SigilDERG-Data_Production) and [SigilDERG-Finetuner](https://github.com/Superuser666-Sigil/SigilDERG-Finetuner), see [ARCHITECTURE.md](https://github.com/Superuser666-Sigil/SigilDERG-Data_Production/blob/main/ARCHITECTURE.md) in the Data Production repository.

## About the SigilDERG Ecosystem

This evaluation harness is part of an integrated pipeline for training and evaluating Rust code generation models:

1. **[SigilDERG-Data_Production](https://github.com/Superuser666-Sigil/SigilDERG-Data_Production)**: Generates high-quality, instruction-style Rust code datasets from real-world crates using static analysis and quality filters
2. **[SigilDERG-Finetuner](https://github.com/Superuser666-Sigil/SigilDERG-Finetuner)**: Fine-tunes language models (like Llama-3.1-8B-Instruct) on Rust code using QLoRA and multi-phase training strategies
3. **HumanEval Rust** (this project): Evaluates model performance on standardized Rust programming problems using the HumanEval benchmark format
4. **[sigil-mmf-codex-priv](https://github.com/Superuser666-Sigil/sigil-mmf-codex-priv)**: Additional components for the ecosystem

### Target Model

This evaluator is designed to work with fine-tuned Rust code generation models, particularly:
- **[Llama-3.1-8B-Instruct-Rust-QLora](https://huggingface.co/Superuser666-Sigil/Llama-3.1-8B-Instruct-Rust-QLora)**: A Phase 1 fine-tuned model produced using the SigilDERG Finetuner

## Installation

### Prerequisites

This package requires **Python 3.12.10 or later**. We recommend using a virtual environment:

```bash
# Using venv (recommended)
python3.12 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Or using uv (fast alternative)
uv venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
```

Install a Rust toolchain via [`rustup`](https://www.rust-lang.org/tools/install) and ensure a modern compiler with Edition 2021 support (Rust 1.56+; we recommend the latest stable toolchain):
```bash
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup default stable
rustc --version
```

### Install from PyPI

```bash
pip install human-eval-rust
```

📦 **Package available on PyPI**: [https://pypi.org/project/human-eval-rust/](https://pypi.org/project/human-eval-rust/)

### Install Full Ecosystem

Install all three SigilDERG packages together:

```bash
pip install human-eval-rust[ecosystem]
```

Or install via the pipeline package:

```bash
pip install sigil-pipeline[ecosystem]
```

This installs:
- `human-eval-rust>=2.1.0`
- `sigil-pipeline>=2.2.1`
- `sigilderg-finetuner>=2.8.0`

### Install from source

```bash
git clone https://github.com/Superuser666-Sigil/human-eval-Rust.git
cd human-eval-Rust
pip install -e .
```

## Usage

**⚠️ Security Warning**: This program exists to run untrusted model-generated Rust code. Users are strongly encouraged not to do so outside of a robust security sandbox. Rust completions are compiled and executed via [`rust_execution.py`](human_eval/rust_execution.py); you should sandbox the Rust evaluator, because it builds binaries from untrusted code and runs their tests locally.

### Basic Evaluation Workflow

1. **Generate completions** from your model using the HumanEval Rust prompts
2. **Save samples** in JSONL format with `task_id` and `completion` fields
3. **Run evaluation** to get pass@k metrics and detailed results

### Example: Evaluating a Fine-Tuned Model

```python
from human_eval.data import read_problems, write_jsonl, get_human_eval_dataset
from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import AutoPeftModelForCausalLM
import torch

# Load your fine-tuned PEFT model (e.g., from HuggingFace)
# For checkpoint subdirectories, use: "repo-name/checkpoint-9000"
model_name = "Superuser666-Sigil/Llama-3.1-8B-Instruct-Rust-QLora/checkpoint-9000"

# Load tokenizer (try checkpoint subfolder first, fallback to repo root)
try:
    tokenizer = AutoTokenizer.from_pretrained(model_name)
except Exception:
    # Fallback: load from repo root or base model
    repo_name = model_name.split("/checkpoint-")[0] if "/checkpoint-" in model_name else model_name
    tokenizer = AutoTokenizer.from_pretrained(repo_name)

# Load PEFT model with explicit parameters to avoid TensorFlow loading issues
model = AutoPeftModelForCausalLM.from_pretrained(
    model_name,
    dtype=torch.bfloat16,
    device_map="auto",
    trust_remote_code=True,
    from_tf=False,  # Explicitly prevent TensorFlow loading
    use_safetensors=True,  # Prefer SafeTensors format
)

# For base models (not PEFT), use:
# model = AutoModelForCausalLM.from_pretrained(
#     model_name,
#     dtype=torch.bfloat16,
#     device_map="auto",
#     trust_remote_code=True,
#     from_tf=False,
#     use_safetensors=True,
# )

# Load HumanEval Rust problems
rust_problems = read_problems(get_human_eval_dataset())

# Generate completions
samples = []
for task_id, problem in rust_problems.items():
    prompt = problem["prompt"]
    
    # Generate completion (adjust parameters as needed)
    inputs = tokenizer(prompt, return_tensors="pt")
    with torch.no_grad():
        outputs = model.generate(
            **inputs,
            max_new_tokens=512,
            temperature=0.2,
            do_sample=True,
        )
    completion = tokenizer.decode(outputs[0][inputs.input_ids.shape[1]:], skip_special_tokens=True)
    
    samples.append(dict(task_id=task_id, completion=completion))

# Save samples
write_jsonl("rust_samples.jsonl", samples)

# Evaluate
# Run: evaluate_functional_correctness rust_samples.jsonl
```

### Command-Line Evaluation

```bash
$ evaluate_functional_correctness rust_samples.jsonl
Reading samples...
164it [00:01, 1959.50it/s]
Running test suites...
100%|...| 164/164 [00:45<00:00,  3.62it/s]
Writing results to rust_samples.jsonl_results.jsonl...
100%|...| 164/164 [00:00<00:00, 42876.84it/s]
{'pass@1': 0.42, 'pass@10': 0.68, 'pass@100': 0.85}
```

The evaluator provides detailed results in `<input>_results.jsonl` with per-sample pass/fail status and execution results ("passed", "timed out", or "failed").

### Integration with SigilDERG Finetuner

The evaluation workflow integrates seamlessly with the [SigilDERG Finetuner](https://github.com/Superuser666-Sigil/SigilDERG-Finetuner) evaluation system:

1. **After training**: Use the finetuner's evaluation scripts to generate samples
2. **Run this evaluator**: Process the generated samples to get HumanEval metrics
3. **Compare metrics**: Track improvements across training phases

Example integration:
```bash
# After Phase 1 training, evaluate checkpoint
python scripts/generate_samples.py \
  --checkpoint out/llama8b-rust-qlora-phase1/checkpoint-1000 \
  --output eval_samples.jsonl

# Evaluate with HumanEval Rust
evaluate_functional_correctness eval_samples.jsonl \
  --problem_file=data/HumanEval_rust.jsonl
```

### Quick Sanity Check

The example samples should yield 0.5 pass@1:
```bash
$ evaluate_functional_correctness data/example_rust_samples.jsonl --problem_file=data/example_rust_problem.jsonl
Reading samples...
4it [00:00, 1959.50it/s]
Running test suites...
100%|...| 4/4 [00:03<00:00,  1.13it/s]
Writing results to data/example_rust_samples.jsonl_results.jsonl...
100%|...| 4/4 [00:00<00:00, 1536.38it/s]
{'pass@1': 0.5}
```

### Advanced Options

```bash
# Custom pass@k values
evaluate_functional_correctness samples.jsonl --k=1,5,10,20

# Adjust parallelism (default: 24 workers optimized for H100)
evaluate_functional_correctness samples.jsonl --n_workers=8

# Custom timeout (default: 10.0s optimized for H100)
evaluate_functional_correctness samples.jsonl --timeout=5.0

# Sandboxing options
evaluate_functional_correctness samples.jsonl --sandbox-mode=firejail  # Recommended
evaluate_functional_correctness samples.jsonl --sandbox-mode=none      # UNSAFE: local dev only

# Non-interactive mode (for CI/automated pipelines)
evaluate_functional_correctness samples.jsonl --allow-no-sandbox  # Required when Firejail unavailable

# Policy enforcement (pattern filtering)
evaluate_functional_correctness samples.jsonl --enforce-policy  # Default: enabled
evaluate_functional_correctness samples.jsonl --no-enforce-policy  # Disable for pure HumanEval compatibility

# See all options
evaluate_functional_correctness --help
```

### Security and Sandboxing

**⚠️ Important**: This evaluator runs untrusted LLM-generated Rust code. For production use, **always use Firejail sandboxing**.

The evaluator includes multiple layers of security:

1. **Pattern-based filtering** (optional, enabled by default): Blocks dangerous code patterns before execution (filesystem, network, process operations, unsafe code, etc.). Can be disabled with `--no-enforce-policy` for pure HumanEval compatibility.
2. **Process isolation**: Each evaluation runs in a separate process
3. **Firejail sandboxing** (recommended): Full process jail isolation with resource limits

**Policy Enforcement Modes**:
- `--enforce-policy` (default): Enables pattern-based filtering for security. Use this for production evaluation of untrusted LLM-generated code.
- `--no-enforce-policy`: Disables pattern filtering for pure HumanEval compatibility. Use this when you need exact 1:1 comparability with the original HumanEval benchmark format (research/publication mode).

**Sandbox Modes**:
- `firejail` (recommended): Uses Firejail for Linux process isolation with `--net=none`, private filesystem, memory/CPU limits
- `none`: No sandboxing (UNSAFE - only for local development with trusted code)
- Auto-detect (default): Automatically detects Firejail availability; prompts for installation or unsafe mode if unavailable

**Firejail Setup** (Linux only):
```bash
# Install Firejail
sudo apt-get install firejail  # Debian/Ubuntu
# or
sudo dnf install firejail      # Fedora/RHEL
# or
sudo yum install firejail      # CentOS
# or
sudo pacman -S firejail        # Arch Linux
```

**Interactive Installation Flow**:

When Firejail is not available, the evaluator presents an interactive prompt:
1. **Install Firejail**: Attempts automatic installation via system package manager
2. **Cancel**: Exit without running evaluation
3. **Proceed without sandbox**: Only after explicit confirmation (UNSAFE)

**Non-Interactive Mode**:

For CI/CD pipelines or automated scripts, use the `--allow-no-sandbox` flag to bypass interactive prompts:
```bash
# In CI, when Firejail is available
evaluate_functional_correctness samples.jsonl --sandbox-mode=firejail

# In CI, when you've verified the environment is secure
evaluate_functional_correctness samples.jsonl --sandbox-mode=none --allow-no-sandbox
```

## Dataset Format

The HumanEval Rust dataset (`data/HumanEval_rust.jsonl`) contains 164 Rust programming problems. Each problem includes:
- `task_id`: Unique identifier (e.g., "HumanEval/0")
- `prompt`: Function signature and docstring
- `canonical_solution`: Reference implementation
- `test`: Rust test cases using `#[cfg(test)]`
- `entry_point`: Function name

Sample format:
```json
{"task_id": "HumanEval/0", "prompt": "fn has_close_elements(...) -> bool{", "canonical_solution": "...", "test": "#[cfg(test)]\nmod tests {...}", "entry_point": "has_close_elements"}
```

### Enhanced Prompt Format (v1.4.4+)

When using the SigilDERG evaluation pipeline (lambda-package), prompts are automatically enhanced with Rust-specific instructions:

- Includes the Rust function signature and doc comment from the problem
- Adds explicit instructions: "Implement only the requested function in Rust"
- Prohibits `fn main`, tests, example code, and unnecessary comments
- Prohibits `...`, `todo!()`, and `unimplemented!()`
- Includes Rust-specific reminders about imports and mutability

This ensures models generate focused, correct Rust code without extra scaffolding.

## Integration with SigilDERG Pipeline

### Complete Workflow

1. **Data Production** → Generate training data with [SigilDERG-Data_Production](https://github.com/Superuser666-Sigil/SigilDERG-Data_Production)
2. **Model Fine-Tuning** → Train on Rust code with [SigilDERG-Finetuner](https://github.com/Superuser666-Sigil/SigilDERG-Finetuner)
3. **Evaluation** → Assess performance with this HumanEval Rust harness
4. **Iteration** → Use results to guide further training and data collection

### Metrics and Benchmarking

This evaluator provides comprehensive metrics for Rust code generation:

**Standard HumanEval Metrics:**
- **pass@k**: Functional correctness at k samples (pass@1, pass@2, pass@10, pass@100)

**Enhanced Metrics (v1.4.4+):**
- **compile_rate**: Fraction of samples that compile successfully
- **main_free_rate**: Percentage of completions without `fn main()` functions

**Result Schema (v1.4.4+):**
Each evaluation result includes enhanced fields for trust and auditability:
```json
{
  "task_id": "HumanEval/0",
  "completion": "...",
  "compile_ok": true,
  "test_ok": true,
  "error_type": null,
  "stderr": "",
  "main_free": true,
  "passed": true,
  "result": "passed"
}
```

**Error Types:**
- `infra_missing_toolchain`: Infrastructure failure (rustc not available)
- `compile_error`: Code failed to compile
- `runtime_error`: Code compiled but crashed during execution
- `assertion_failure`: Tests failed (code ran but assertions failed)

**Preflight Checks:**
- Validates `rustc` availability before evaluation (fails fast on infrastructure issues)
- Never drops completions silently - all samples are included in results with appropriate status

Together, these metrics provide a complete picture of model performance for Rust code generation, with full auditability for Rule Zero compliance.

## Hardware Optimizations (H100 Configuration)

Version 2.0.0+ includes optimizations specifically tuned for high-performance GPU evaluation environments (e.g., 1x H100 with 26 vCPUs and 225GB RAM):

### Default Configuration
- **Parallel Workers**: 24 (default `--n_workers=24`) - Optimized to saturate 26 vCPUs (reserving 2 for OS/orchestration)
- **Timeout**: 10.0 seconds (default `--timeout=10.0`) - Increased from 3.0s to handle compilation latency on loaded systems
- **Firejail Memory Limit**: 4GB per process - Handles complex, macro-heavy Rust code compilation

### Resource Usage
With 24 workers and 4GB memory per process:
- **Maximum Memory Usage**: ~96GB (24 workers × 4GB) - Well within 225GB safety margin
- **CPU Utilization**: ~92% (24/26 vCPUs) - Near-saturation for maximum throughput

These defaults are optimized for production evaluation on high-end hardware. For smaller systems, you can override with `--n_workers` and `--timeout` flags.

## Version 2.0.0 Breaking Changes

**Docker Support Removed**: Version 2.0.0 removes Docker-based sandboxing in favor of Firejail-first architecture:
- Simpler deployment: No Docker daemon required
- Faster startup: No container overhead
- Interactive installation: Prompts to install Firejail if missing
- Non-interactive mode: `--allow-no-sandbox` for CI/CD pipelines

**Migration from v1.x**:
- If you were using `--sandbox-mode=docker`, switch to `--sandbox-mode=firejail`
- Install Firejail on your system (see Firejail Setup above)
- For CI/CD, use `--allow-no-sandbox` if running in a secure environment without Firejail

## Version 1.3.2+ Features

**Completion Extraction & Cleaning:**
- Automatically extracts function bodies from model completions
- Removes extra `main()` functions and standalone code
- Strips markdown code blocks (```rust, ```)
- Handles completions with or without function signatures
- Improves evaluation accuracy by ensuring only the target function is tested

**Robust Validation:**
- Validates `rustc` availability before evaluation (fails fast if unavailable)
- Prevents silent failures across thousands of samples

## Known Issues

While evaluation uses very little memory, you might see the following error message when the system is running out of RAM. Since this may cause some correct programs to fail, we recommend that you free some memory and try again.
```
malloc: can't allocate region
```
