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, it assumes that MacPorts is already installed and no cleanup is needed.

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.
