Locate the section for your github remote in the .git/config file. It looks like this:
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = [email protected]:joyent/node.git
Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
| # Except sqlite3 all the libraries are standard that should be present with a Ruby installation. | |
| # If you don't have sqlite3 installed. Use `gem install sqlite3` | |
| require 'fileutils' | |
| require 'sqlite3' | |
| require 'uri' | |
| require 'net/http' | |
| require 'set' | |
| require 'thread' |
