Checkout github pull requests locally

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:

Get SSH working on Vagrant/Windows/Git

If you are using vagrant, you probably-statistically are using git. Make sure you have its binary folder on your path, because that path contains 'ssh.exe'.

Now, modify C:\vagrant\vagrant\embedded\lib\ruby\gems\1.9.1\gems\vagrant-1.0.3\lib\vagrant\ssh.rb to comment out the faulty Windows check and add a real SSH check:

# if Util::Platform.windows?
  # raise Errors::SSHUnavailableWindows, :host => ssh_info[:host],
                                       # :port => ssh_info[:port],
                                       # :username => ssh_info[:username],
 # :key_path => ssh_info[:private_key_path]
