This tool allows users to find the earliest release that contains a specific PR or commit.
It runs entirely in the browser using a static JSON index generated from the git history.
## Usage
1. **Generate the Index**:
Run the Python script to generate the `release_index.json` file from your local git repository.
```bash
python3 generate_index.py --output release_index.json
```
This script:
- Finds all tags matching `v*` and `gateway-v*`.
- Sorts them by creation date.
- Traverses the history to find which release first introduced each commit and PR.
- Extracts PR numbers from commit messages.
2. **Open the Tool**:
Open `index.html` in your browser.
```bash
# You can open it directly if your browser supports local file fetch (Firefox usually does),
# or serve it locally:
python3 -m http.server
# Then go to http://localhost:8000/index.html
```
## Files
- `index.html`: The UI for the lookup tool.
- `generate_index.py`: Script to build the index.
- `release_index.json`: The index file used by the UI.
## Logic
The tool determines the "earliest release" based on the tag creation date. It traverses tags from oldest to newest. Any commit reachable from a tag (that wasn't reachable from a previous tag) is assigned to that release.
