| | # Instructed Lint Python Files |
| |
|
| | Lint-annotated Python source code from [bigcode/the-stack-dedup](https://huggingface.co/datasets/bigcode/the-stack-dedup), |
| | processed with [ruff](https://github.com/astral-sh/ruff) (all 800 stable rules enabled). |
| |
|
| | ## Dataset Description |
| |
|
| | This dataset pairs **12,962,249 Python files** from The Stack (deduplicated) with their complete |
| | ruff lint diagnostics. Each record contains the original source code, file metadata, license |
| | information, and structured lint results. |
| |
|
| | ### Motivation |
| |
|
| | Building training data for code quality models requires large-scale lint annotations. Running |
| | ruff at scale on millions of files is expensive with the standard CLI approach. We built |
| | [ruff-batch](https://github.com/astral-sh/ruff), a Rust binary that calls ruff's internal |
| | `lint_only()` API directly via Rayon parallel iteration, achieving **26,337 files/sec** with all |
| | 800 rules enabled — a **10x speedup** over the ruff CLI. |
| |
|
| | ### Source Data |
| |
|
| | - **Origin**: [bigcode/the-stack-dedup](https://huggingface.co/datasets/bigcode/the-stack-dedup), Python split |
| | - **Files**: 12,962,249 |
| | - **Linter**: ruff (all 800 stable rules, preview disabled) |
| | - **Processing time**: 8.2 minutes on Apple M3 Ultra (28 cores) |
| |
|

| | | `message` | string | Human-readable description of the issue | |
| | | `row` | int | 1-indexed start line number | |
| | | `col` | int | 1-indexed start column number | |
| | | `end_row` | int | 1-indexed end line number | |
| | | `end_col` | int | 1-indexed end column number | |

| |
|
| | - **Total files**: 12,962,249 |
| | - **Valid syntax**: 95.6% |
| | - **Average diagnostics per file**: ~102 (with all 800 rules) |
| | - **Total diagnostics**: ~1.3 billion |

|
| | ## Usage |
| |
|
| | ```python |
| | from datasets import load_dataset |
| | |
| | ds = load_dataset("tensorvalley/instructed_lint_python_files", split="train", streaming=True) |
| | |
| | for record in ds: |
| | print(f"File: {record['path']}") |
| | print(f"License: {record['max_stars_repo_licenses']}") |
| | print(f"Issues: {record['num_diagnostics']}") |
| | for diag in record['diagnostics']: |
| | span = f"L{diag['row']}:{diag['col']}-L{diag['end_row']}:{diag['end_col']}" |
| | print(f" {diag['code']} [{span}]: {diag['message']}") |
| | break |
| | ``` |
| |
|
| | ## Licensing and Attribution |
| |
|
| | This dataset contains source code from GitHub repositories with **various open-source licenses**. |
| | The license for each file is provided in the `max_stars_repo_licenses` field. **Any use of the |
| | code must comply with the terms of the original licenses**, including attribution requirements. |
| |
|
| | The lint annotations themselves are provided under [Apache-2.0](https://www.apache.org/licenses/LICENSE-2.0). |
| |
|
| | For data provenance, each record includes: |
| | - `id`: The git hexsha, which can be used to trace back to the original commit |
| | - `max_stars_repo_name`: The GitHub repository name for attribution |
| | - `path`: The original file path within the repository |
| |
|
| | ## Data Removal |
| |
|
| | This dataset inherits The Stack's data removal policy. If your code is included and you wish to |
| | have it removed, please follow the opt-out process at |
| | [Am I in The Stack?](https://huggingface.co/spaces/bigcode/in-the-stack) |
| |
|
| | When The Stack publishes data removal updates, this dataset will be updated accordingly. Follow |
| | the [update thread](https://huggingface.co/datasets/bigcode/the-stack/discussions/7) for |
| | notifications. |
| |
|
| | ## Security Warning |
| |
|
| | **This dataset contains raw source code from public GitHub repositories. Some files may contain:** |
| |
|
| | - Security vulnerabilities (SQL injection, XSS, command injection, etc.) |
| | - Intentionally malicious code |
| | - Backdoors or exploits |
| | - Credential leaks or hardcoded secrets |
| |
|
| | **Do not execute any code from this dataset without thorough security review.** The ruff lint |
| | annotations identify some code quality issues but are **not a security audit** and should not |
| | be treated as one. |

| | ## Artifacts |
| | - Rule frequency stats (`rule_stats.json`): per-rule counts over the dataset split (how many files contain each diagnostic code + total diagnostic occurrences), used to pick a balanced ~100-rule subset for GRPO. |
