Thin

Thanks to Thomas Glasgow, I've been told of a new lighter Mongrel web server called THIN. It's more-so a cut-down version of the Mongrel Web Server, with the added power of an Event machine and Rack parser.

Haven't tested it out, but intend to try it out on one of my apps, install it with...

sudo gem install thin

• mongrel thin

Thin - Rake Task

• thin startup scripts

With the above I found a startup script similar to Monrel's .yml config file.

namespace :thin do
  namespace :cluster do

    desc 'Start thin cluster'
    task :start => :environment do
      `cd #{RAILS_ROOT}`
      port_range = RAILS_ENV == 'development' ? 3 : 8
      (ENV['SIZE'] ? ENV['SIZE'].to_i : 4).times do |i|
        Thread.new do
           port = ENV['PORT'] ? ENV['PORT'].to_i + i : ("#{port_range}
%03d" % i)
          str  = "thin start -d -p#{port} -Ptmp/pids/thin-#{port}.pid"
          str += " -e#{RAILS_ENV}"
          puts "Starting server on port #{port}..."
          `#{str}`
        end
      end
    end

    desc 'Stop all thin clusters'
    task :stop => :environment do
      `cd #{RAILS_ROOT}`
      Dir.new("#{RAILS_ROOT}/tmp/pids").each do |file|
        Thread.new do
          if file.starts_with?("thin-")
            str  = "thin stop -Ptmp/pids/#{file}"
            puts "Stopping server on port #{file[/\d+/]}..."
            `#{str}`
          end
        end
      end
    end

  end
end

copy and paste it into a .rake task in your apps /lib/tasks directory.

then fire with...

rake thin:cluster:start
rake thin:cluster:stop

and...

rake thin:cluster:start RAILS_ENV=production SIZE=10 PORT=8000

• SIZE = cluster size (2 is usually enough)
• RAILS_ENV = environment (production, development or test)
• PORT = port range to start from (for 2 clusters it'll be 8000 and 8001)

Thanks to Stephen Celis for this.

Fedora Package Errors and Cleanups

Lately i've run into some problems with my Fedora package manager, inconsistent files and dropped repositories. However I think I've managed to cleanup this problem by first cleaning up my package managers metadata, db cache and doing a general tidyup with...

sudo yum clean all
sudo yum clean metadata
sudo yum clean dbcache

Then giving the once-over of my RPM repository,

sudo rpm -vv --initdb

This looked ok, but I wanted to make sure so I rebuilt my RPM repository,

sudo rm -f /var/lib/rpm/__db*
sudo rpmdb -vv --rebuilddb

Now looking a little better,

Want to install Beryl + Compiz to get the 3D effects and cubed desktop next.

• Beryl + Compiz

Update on Beryl

After hunting around I found that Beryl has been dropped in favour of Compiz, so don't go hunting for it because you won't find it.
