|

|
|
| ## Overview |
|
|
| **Themis-Git-Commits-Merged** is a large-scale dataset of ~3.98M single-file code commits from **permissively licensed** GitHub repositories that have been cross-referenced with [GHTorrent](https://ghtorrent.org/) pull request data to retain only commits that are part of **successfully merged, non-reverted pull requests**. This provides implicit human validation of each code change — a merge decision by project maintainers confirms the intent and quality of the commit. |
|
|
| This dataset is derived from [Themis-Git-Commits](https://huggingface.co/datasets/project-themis/git-commits) (the raw, unfiltered commit pool) by joining against GHTorrent pull request records through **end of 2021** (the temporal extent of the GHTorrent PR data used). It serves as the direct input to the aspect classification and preference construction stages of the [Themis](https://github.com/iNeil77/Themis) pipeline, which produces the commit-based preference pairs in [Themis-CodePreference](https://huggingface.co/datasets/project-themis/Themis-CodePreference) and [Themis-CodeRewardBench](https://huggingface.co/datasets/project-themis/Themis-CodeRewardBench). |
|
|
| The SQL query used for initial commit mining restricts to repositories under permissive open-source licenses only (MIT, Apache-2.0, BSD-2/3-Clause, ISC, CC0-1.0, EPL-1.0, MPL-2.0, Unlicense, AGPL-3.0, LGPL-2.1, Artistic-2.0). The BigQuery snapshot used contains commits up to **early 2022** — predating the widespread availability of LLM code generation tools — ensuring that all code changes in the dataset represent **genuine human-authored preferences**. |
|

| ## Relationship to Themis-Git-Commits |

|
|
| | | [Themis-Git-Commits](https://huggingface.co/datasets/project-themis/git-commits) | **Themis-Git-Commits-Merged** (this dataset) | |
| |:---|:---|:---| |
| | **Scope** | All mined single-file commits | Only commits in merged, non-reverted PRs | |
| | **Extension filtering** | No | Yes (file extension matches target language) | |
| | **PR validation** | No | Yes (via GHTorrent, through end of 2021) | |
| | **Human validation** | Implicit (authored by humans) | Explicit (merge decision by maintainers) | |
| | **Downstream use** | Raw pool for further filtering | Direct input to aspect classification | |
|
|
| </div> |
|
|
| ## Collection Pipeline |
|
|
| The commit mining pipeline is described in detail in the [Themis paper](https://arxiv.org/abs/2605.00754) and the [Dataset](https://github.com/iNeil77/Themis/tree/main/Dataset) folder in the GitHub repository. The BigQuery SQL query and scraping infrastructure are modified from the [OctoPack](https://arxiv.org/abs/2308.07124) pipeline ([CommitPack](https://huggingface.co/datasets/bigcode/commitpack)); the subsequent filtering, classification, and preference construction stages are original to Themis. |

| 1. **BigQuery Mining** — A [GoogleSQL query](https://github.com/iNeil77/Themis/blob/main/Dataset/Commit_Mining_SQL/consolidated_query.sql) (modified from [OctoPack](https://arxiv.org/abs/2308.07124)) extracts single-file commits from **permissively licensed** repositories in `bigquery-public-data.github_repos`, filtering for target programming languages and non-trivial commit messages. |
|
|
| 2. **Repository Reputation Filtering** — Commits are subset to those originating from [curated high-reputation repositories](https://github.com/iNeil77/Themis/tree/main/Dataset/Repos) (15+ GitHub stars, 5+ contributors, 10+ issues). |
|
|
| 3. **Extension Filtering** — Commits are further filtered so the changed file's extension matches a target programming language. |
|
|
| 4. **Content Retrieval** — The pre-commit (`old_contents`) and post-commit (`new_contents`) file contents are fetched from GitHub via shallow git fetches using [retrieve_commit_contents.py](https://github.com/iNeil77/Themis/blob/main/Dataset/Utils/retrieve_commit_contents.py). |
|
|
| 5. **MinHash Deduplication** — Near-duplicate content is removed using [MinHash LSH deduplication](https://github.com/iNeil77/Themis/blob/main/Dataset/Utils/minHash_dedupe_local.py) (shingle size 5, 256 permutations, Jaccard threshold 0.7). |
|
|
| 6. **Pull Request Cross-Referencing** *(this step produces this dataset)* — Commits are joined with [GHTorrent](https://ghtorrent.org/) pull request data (through **end of 2021**) to retain only non-reverted commits that are part of successfully merged pull requests from reputable repositories, ensuring implicit human validation of each code change. |
|
|
| ## Downstream Processing (Not in This Dataset) |
|
|
| The steps below are applied downstream to produce the final preference pairs in Themis-CodePreference and Themis-CodeRewardBench, and are **not** reflected in this dataset: |
|
|
| - **Language Subsetting** — The 24 languages in this dataset are narrowed to the 8 target languages (C, C#, C++, Go, Java, JavaScript, Python, Ruby) used in [Themis-CodePreference](https://huggingface.co/datasets/project-themis/Themis-CodePreference) and [Themis-CodeRewardBench](https://huggingface.co/datasets/project-themis/Themis-CodeRewardBench). |
| - **Temporal Subsetting** — For training data ([Themis-CodePreference](https://huggingface.co/datasets/project-themis/Themis-CodePreference)), only commits pushed before **March 2019** are retained. For benchmark data ([Themis-CodeRewardBench](https://huggingface.co/datasets/project-themis/Themis-CodeRewardBench)), commits are scoped to **June 2019 – January 2021** from disjoint repositories. |
| - **Aspect Classification** — Commits are assigned to quality dimensions (Functional Correctness, Runtime Efficiency, Memory Efficiency, Security Hardness, Readability & Maintainability) using criteria-specialized [ModernBERT](https://huggingface.co/answerdotai/ModernBERT-base) commit classifiers, trained on seed positives retrieved via [curated term lists](https://github.com/iNeil77/Themis/tree/main/Dataset/Commit_Mining_Terms). |
| - **LLM Scoring & Instruction Synthesis** — Frontier LMs validate preference strength and generate realistic inverse instructions. |
| - **LLM-as-a-Judge Preference Labelling** — Multi-sample voting with frontier LMs produces consensus preference labels. |

| ## Dataset Schema |
|
|
| <div align="center"> |
|
|
| | Column | Type | Description | |
| |:---|:---:|:---| |
| | `commit` | string | Git commit SHA | |
| | `subject` | string | First line of the commit message | |
| | `message` | string | Full commit message body | |
| | `repos` | string | Comma-separated list of repository names containing this commit | |
| | `file_path` | string | Path of the changed file | |
| | `license` | string | SPDX license identifier of the source repository | |
| | `unix_time` | int64 | Committer timestamp (seconds since epoch) | |
| | `new_contents` | string | File contents after the commit (post-commit) | |
| | `old_contents` | string | File contents before the commit (pre-commit) | |
|
|
| </div> |
|
|
| ## Language Distribution |
|
|
| The dataset is partitioned by programming language, with one config per language. Each config has a single `train` split. |
|
|
| <div align="center"> |
|
|
| | Language | Commits | | Language | Commits | |
| |:---|---:|:---|:---|---:| |
| | Python | 914,849 | | Rust | 57,383 | |
| | JavaScript | 694,051 | | Scala | 46,557 | |
| | Java | 402,369 | | Swift | 40,271 | |
| | Ruby | 345,124 | | Groovy | 16,723 | |

| ## Filters Applied |
|
|
| All filters from the upstream [Themis-Git-Commits](https://huggingface.co/datasets/project-themis/git-commits) pipeline apply, plus the PR merge filter: |
|
|
| <div align="center"> |
|
|
| | Filter | Purpose | |
| |:---|:---| |
| | **License allowlist** | MIT, Apache-2.0, BSD-2-Clause, BSD-3-Clause, ISC, CC0-1.0, EPL-1.0, MPL-2.0, Unlicense, AGPL-3.0, LGPL-2.1, Artistic-2.0 | |
| | **Language allowlist** (SQL) | Python, Java, JavaScript, C, C#, C++, TypeScript, Go, Ruby (repo-level filter in BigQuery query) | |
| | **Message length** | 10 < length < 15,000 characters | |
| | **Message blocklist** | ~50 low-signal messages excluded (e.g., "initial commit", "wip", "yolo") | |
| | **Pattern exclusion** | Merge commits and CI push messages filtered out | |
| | **Same-path constraint** | `old_path = new_path` — file was modified in place, not renamed or moved | |
| | **Single-file constraint** | Commit touches exactly one file | |
| | **Content retrieval** | Both pre-commit and post-commit file contents successfully fetched | |
| | **Near-deduplication** | MinHash LSH with Jaccard threshold 0.7 | |
| | **Extension filtering** | Changed file's extension mapped to one of 24 target programming languages (see distribution table) | |
| | **PR merge filter** | Commit is part of a successfully merged, non-reverted pull request (GHTorrent data through end of 2021) | |
|
