Capistrano 3.0 - 现在如何安全地提示输入密码？

Question

在此之前3.0有一种方法可以做到这一点:

# ...
set :mysql_password, proc { Capistrano::CLI.password_prompt "Gimme remote database server password. Don't worry, I won't tell anyone: " }
# ...

namespace :db do
  desc 'Dump remote database'
  task :dump do
    run "mysqldump -u #{mysql_user} -p #{mysql_database} > ~/#{mysql_database}.sql" do |channel, stream, data|
      if data =~ /^Enter password:/
        channel.send_data "#{mysql_password}\n"
      end
    end
  end
end

它提示输入密码,在您键入时不显示密码,并且在日志和输出中不留下任何痕迹.

现在,作为3.0我发现的唯一方式:

# ...

namespace :db do
  desc 'Dump remote database'
  task :dump do
    ask :mysql_password, nil
    on roles(:db) do
      execute "mysqldump -u#{fetch :mysql_user} -p#{fetch :mysql_password} #{fetch :mysql_database} > ~/#{fetch :mysql_database}.sql"
    end
  end
end

它完成了这项工作,但随处可见密码.

有没有人找到一种安全的密码提示方式3.0？谢谢!
