Capistrano might ask for a password when:

   1  # Capistrano is using sudo, so set it to false
   2  set :use_sudo, false
   3  
   4  # Your remote server is trying to checkout an SSH protected Git repository
   5  set :repository, '/var/git/repositories/xxx.git' # Remote server also holds the git repository
   6  set :local_repository, 'ssh://xxx/var/git/repositories/xxx.git' # Your development machine points to the remote machine 
   7  
   8  # SSH settings, also see ~/.ssh/config
   9  set :user, "jebus"
  10  set :domain, 'xxx.com'
  11  set :port, 666
  12  
  13  # Other settings worth checking
  14  ssh_options[:forward_agent] = true
  15  ssh_options[:keys] = [File.join(ENV["HOME"], ".ssh", "id_rsa")]
  16  default_run_options[:pty] = true # see http://www.mail-archive.com/capistrano@googlegroups.com/msg07323.html for details

How to setup a password-less “cap deploy” with Capistrano

   1  @groups = @products.group_by { |product| product.name.mb_chars[0].downcase.to_s }.sort

If you’re using mb_chars, remember to call “to_s” or you won’t get what you expect.

Git might give you this fine error

   1  fatal: protocol error: bad line length character:

Looks like git didn’t receive the response it expected from your server.

Possible causes:

• Did you put some echo commands in e.g. ~/.bashrc on the remote server?

Sed will croak on OSX. Use Perl instead.

Replace HoptoadNotifier with Airbreak:

   1  perl -e "s/HoptoadNotifier/Airbreak/g;" -pi $(find . -type f)

On Linux sed might work:

   1  # Find, backup and replace
   2  find . -name "*.rb" -print | xargs sed -i.bak 's/HoptoadNotifier/Airbreak/g'
   3  # Delete backup files
   4  find . -name '*.bak' -type f -delete
