| # GitHub Pull Request Bug–Fix Dataset |
|
|
| A **curated, high-signal dataset of real-world software bugs and fixes** collected from **25 popular open-source GitHub repositories**. |
| Each entry corresponds to a **single pull request (PR)** and pairs contextual metadata with the **exact code changes (unified diffs)** that fixed the bug. |
|
|
| This dataset is designed for: |
|
|
| - **Automated program repair** |
| - **Bug-fix patch generation** |
| - **LLM-based code and debugging agents** |
| - **Empirical software engineering research** |
|
|
| --- |
|
|
| ## Data collection methodology |
|
|
| Data was collected using the **GitHub REST API** and post-processed into a structured format. |
|
|
| To maintain quality and usefulness: |
|
|
| - Only **merged pull requests** were included |
| - Each PR must represent a **bug fix or correctness change** |
| - Fixes are linked to both the **buggy commit** and the **fix commit** |
| - Code changes are stored as **unified diffs** at the file level |
| - Low-signal PRs (refactors, formatting-only changes, discussions) were filtered out |
| - PRs without meaningful code changes were excluded |
|
|
| Each dataset row represents **one bug–fix PR**. |
|
|
| --- |
|
|
| ## Dataset schema |
|
|
| Each entry follows the schema below: |
|
|
| ```json |
| { |
| "repo": "owner/repository", |
| "pr_number": 12345, |
| "title": "Short description of the fix", |
| "body": "Pull request description and context", |
| "buggy_commit": "abcdef123456...", |
| "fix_commit": "fedcba654321...", |
| "buggy_distance": 12, |
| "confidence": "medium", |
| "files": [ |
| { |
| "filename": "path/to/file.ext", |
| "patch": "unified diff representing the fix", |
| "additions": 10, |
| "deletions": 2 |
| } |
| ] |
| } |
| ``` |
|
|
| | Field | Description | |
| | ------------------- | ------------------------------------------------- | |
| | `repo` | GitHub repository containing the pull request | |
| | `pr_number` | Pull request number | |
| | `title` | Pull request title | |
| | `body` | Pull request description and discussion context | |
| | `buggy_commit` | Commit introducing or containing the bug | |
| | `fix_commit` | Commit that fixes the bug | |
| | `buggy_distance` | Number of commits between buggy and fix commits | |
| | `confidence` | Heuristic confidence level of bug–fix correctness | |
| | `files` | List of files modified by the fix | |
| | `files[].filename` | Path to the modified file | |
| | `files[].patch` | Unified diff containing the code changes | |
| | `files[].additions` | Number of lines added | |
| | `files[].deletions` | Number of lines removed | |
|
|
| ## Supported languages |
|
|
| The dataset contains fixes across multiple programming languages, including (but not limited to): |
|
|
| * C / C++ |
| * Python |
| * JavaScript / TypeScript |
| * Rust |
| * Go |
| * Java |
| * Assembly (very rare) |
|
|
| Language distribution varies by repository. |
|
|
| ## Intended use cases |
|
|
| This dataset is well-suited for: |
|
|
| * Training models to generate patches from real pull request context |
| * Studying bug-fix patterns across large codebases |
| * Building autonomous debugging or repair agents |
| * Research in program repair, code synthesis, and software maintenance |
|
|
| It is not intended for: |
|
|
| * Pull request classification or triage |
| * Sentiment analysis |
| * General-purpose chatbot fine-tuning without code generation objectives |
|
|
| ## Limitations |
| The dataset reflects real-world noise from GitHub pull requests |
| Buggy commit identification is heuristic and may be imperfect |
| Some fixes involve refactoring or design changes rather than minimal patches |
| No guarantee that fixes represent optimal or best-practice solutions |
|
|
| > ⚠️ Warning |
| This dataset currently includes pull requests from 10 of the planned 25 repositories, totaling approximately 24,000 entries. |
| The final release is expected to contain ~50,000 entries and occupy ~2 GB of storage. |
