Bot to manage and test GitHub pull requests

The PR bot processes GitHub webhook events and can be built with go get github.com/macports/mpbot-github/pr/prbot.

The CI bot tests PRs on Travis CI and can be built with go get github.com/macports/mpbot-github/ci/runner.

PR bot

To run the PR bot, you need to set the following environment variables.

In pr/db/dbutil.go, connection strings for the PostgreSQL databases:

• TRAC_DB: connection string for the Trac DB
• WWW_DB: connection string for the PortIndex DB (https://github.com/macports/macports-infrastructure/tree/master/jobs)
• PR_DB: connection string for the bot's own DB

In pr/prbot/main.go, secrets and production flag:

• HUB_WEBHOOK_SECRET: used to verify webhook events
• HUB_BOT_SECRET: used to comment and modify labels in PRs
• BOT_ENV: set to production to actually mention maintainers

You can use -l addr:port to set the listen address for GitHub webhook.

CI bot

The CI bot is executed as root under Travis CI environment bootstrapped by this script. It assumes that MacPorts is already installed and no cleanup is needed.
