# Committer Tools

This directory contains scripts to help Apache Kafka committers with a few chores.
Some of the scripts require a GitHub API token with write permissions. Only
committers will be able to utilize such scripts.

## Requirements

- Python 3.x and pip
- The GitHub CLI

## Installation

### 1. Check Python installation

Check if Python and pip are installed in your system.

```bash
python --version
pip --version
```

### 2. Set up a virtual environment (optional)

```bash
python -m venv venv

# For Linux/macOS
source venv/bin/activate

# On Windows:
# .\venv\Scripts\activate
```

### 3. Install the required dependencies

```bash
pip install -r requirements.txt
```

### 4. Install the GitHub CLI

See: https://cli.github.com/

```bash
brew install gh
```

## Find Reviewers and Update to PR body

The reviewers.py script is used to simplify the process of producing our "Reviewers:"
Git trailer to PR body. It parses the Git log to gather a set of "Authors" and "Reviewers". 
Some simple string prefix matching is done to find candidates. 
After entering the pull request number, the script updates the "Reviewers:" trailer accordingly. 
If the PR body already contains a "Reviewers:" trailer, the script replaces it with the updated list of reviewers.

Usage:

```bash
python reviewers.py
```

## Refresh Collaborators

The Refresh Collaborators script automates the process of fetching contributor
data from GitHub repositories, filtering top contributors who are not part of
the existing committers, and updating a local configuration file (.asf.yaml) to
include these new contributors.

> This script requires the Python dependencies and a GitHub auth token.

You need to set up a valid GitHub token to access the repository. After you
generate it (or authenticate via GitHub CLI), this can be done by setting the
GITHUB_TOKEN environment variable.

```bash
# For Linux/macOS
export GITHUB_TOKEN="your_github_token"
# Or if you use GitHub CLI
export GITHUB_TOKEN="$(gh auth token)"

# On Windows:
# .\venv\Scripts\activate
```

Usage:

```bash
python refresh_collaborators.py
```

## Find Hanging Tests

This script is used to infer hanging tests from the Gradle output. It looks for
tests that were STARTED but do not have a corresponding FINISHED or FAILED.

Usage:

```bash
python find-unfinished-test.py ~/Downloads/logs_28218821016/5_build\ _\ JUnit\ tests\ Java\ 11.txt

Found tests that were started, but not finished:

2024-09-10T20:31:26.6830206Z Gradle Test Run :streams:test > Gradle Test Executor 47 > StreamThreadTest > shouldReturnErrorIfProducerInstanceIdNotInitialized(boolean) > "shouldReturnErrorIfProducerInstanceIdNotInitialized(boolean).processingThreadsEnabled=true" STARTED
```
