This repository contains code which implements a CI (Continuous Integration) service for GitHub. This service is implemented in Ruby. It monitors pull requests and attributes statuses to them. To receive the status success, a pull request needs to fulfill the following conditions:

• the pull request has an assignee
• the assignee needs to leave a comment with body "+1"

The following Ruby gems -along with their own dependencies- are required to run crhub:

• sinatra
• json
• octokit
• sqlite3
• parseconfig
• git
• daemons (only to run in daemon mode, i.e. when using crhub_daemon.rb)

You also need to obtain a GitHub [personal token] (https://github.com/settings/tokens) with the correct scope (repo:status is the only required scope). Copy this token and add it as environment variable GITHUB_PERSONAL_TOKEN to your server.

Clone the crhub repo on your server and run it like this:

ruby crhub.rb <path to crhub conf file>

For example:

ruby crhub.rb crhub.conf

Take a look at the comments in the sample file [crhub.conf] (crhub.conf) for more information.

The final step is to add crhub as a webhook for your repository. Use the following configuration:

• payload url: http://<server_IP_addr>:4567/codereview
• events: Pull Request and Issue Comment

To run crhub as a daemon, simply use the crhub_daemon.rb script instead. The following commands are useful:

ruby crhub_daemon.rb start -- <full path to crhub conf file>
ruby crhub_daemon.rb stop
ruby crhub_daemon.rb restart -- <full path to crhub conf file>
ruby crhub_daemon.rb status

The crhub output will be logged to crhub_daemon.output (in the script's directory).
