A quick fix for Octopress 2 that prevents drafts from being deployed. Preview still possible.

fix_drafts_deployment.rb

desc "Default deploy task"
task :deploy do
  # Check if preview posts exist, which should not be published
  if File.exists?(".preview-mode")
    puts "## Found posts in preview mode, regenerating files ..."
    File.delete(".preview-mode")
    Rake::Task[:generate].execute
  end
  Rake::Task[:copydot].invoke(source_dir, public_dir)

  # exclude drafts in public/ before deployment
  # we compare each post in source/_drafts/ against one in public/
  Dir.foreach("#{args.source}/_drafts") do |item|
    file_ext = File.extname(item) 
    puts "draft file candidate: #{file_ext}"
    if file_ext == ".markdown" or file_ext == ".md"
        file_base = File.basename(item, file_ext) 
        puts "removing a draft: #{public_dir}/#{file_base}"
        rm_rf("#{public_dir}/#{file_base}")
    end
  end
  Rake::Task["#{deploy_default}"].execute
end
