# One million commits

A large variety of git commits pulled from across GitHub.

Created by **William Entriken**, released **2023-09-26**, version **1**.

This composition is licensed under the **MIT license**.

## Intended use

This dataset could be used to train a model concerned with programming tasks:

1. Summarize some programming work
1. Perform work given a description of the work to do
1. Learn-by-example the syntax for all active programming languages and structured data formats

This dataset could be used to train a model concerned with scoring and trend analysis:

1. Identify trends in programming across years
1. Compare popularity and impact of programming topics/languages (using stars, quality as a signal)
1. Score programming work as good or bad (using authors' ratings as a signal)
1. Identify popular project file layouts for each programming language

Because this dataset comprises about a half terabyte of text, it may be useful for a training a general text processing model. Or at least a niche of such a model.

## Factors

An attempt was made at providing a large variety of repositories. To example the potential biases, here is a comparison of our dataset to sampling at random from the list of all commits across GitHub.

1. This dataset should overrepresent repositories with 7+ character words.
1. This dataset should overrepresent repositories with few commits (because only one commit is included per repository).
1. This dataset should overrepresent repositories from authors with many repositories.

## Metrics

* Commits: 1,000,000
* Distinct repositories: 1,000,000
* Distinct authors: xxx
* Bytes: 

## Data format

The files are distributed as SQLite databases with the schema:

```sql
CREATE TABLE commits (repo_full_name TEXT UNIQUE, repo JSON, `commit` JSON, commit_patch TEXT, author JSON);
```

Each repository is included at most once, which is why `repo_full_name` is a unique key. The `commit_patch` is the full `.patch` file for the commit. Other columns `repo`, `commit` and `author` are JSON blobs following the GitHub API schema:

## Methodology

A set of some random words were started as a seed. Then a search was performed against the GitHub API using one of those words, a random acceptable license, a random sort order and direction. Then from each repository, one of the most recent 1,000 commits was randomly selected. And words over seven characters were added back to the random word set. This process repeated one million times.

The acceptable licenses were chosen to include every license which allows that commit to be included in this dataset without me including one million separate licenses notices. Those are (identified by SPDX identifier):

- `apache-2.0`
- `bsl-1.0`
- `bsd-2-clause`
- `bsd-3-clause`
- `0bsd`
- `cc0-1.0`
- `wtfpl`
- `isc`
- `mit`
- `postgresql`
- `unlicense`
- `zlib`

These licenses are identified in the dataset so you are easily able to filter if needed.

## Ethical considerations

Commits on GitHub include author contact information, which is publicly available to anybody even without a GitHub account. This dataset includes that contact information in each commit. This dataset creates a risk for spam unwanted outreach.

I considered whether it was appropriate to attempt redacting such information from the commit patches and contents, and ultimately decided against this.

Taking my own experience in receiving mail I have found that the vast majority of outreach to my GitHub email address (filtered through Gmail) is seemingly legitimate research requests and genuine interview requests, compared to zero apparent evil phishing or selling attempts. And practically, I understand it would be more effective and trivial for an evil spammer to look up individual author's contact information or to harvest it for a specific topic using the GitHub API than downloading and parsing this terabyte-scale dataset.

So overall, the risk was deemed acceptable.

## Caveats and recommendations

The database is not normalized. So you may find that author information in one commit does not match that same author's information in another commit. This is simply an artifact of the data collection process having taken course over a period of weeks rather than a single snapshot.
