+# Sample verbose configuration file for Unicorn (not Rack)
+#
+# This configuration file documents many features of Unicorn
+# that may not be needed for some applications. See
+# http://unicorn.bogomips.org/examples/unicorn.conf.minimal.rb
+# for a much simpler configuration file.
+#
+# See http://unicorn.bogomips.org/Unicorn/Configurator.html for complete
+# documentation.
+
+# Use at least one worker per core if you're on a dedicated server,
+# more will usually help for _short_ waits on databases/caches.
+worker_processes 4
+
+# Since Unicorn is never exposed to outside clients, it does not need to
+# run on the standard HTTP port (80), there is no reason to start Unicorn
+# as root unless it's from system init scripts.
+# If running the master process as root and the workers as an unprivileged
+# user, do this to switch euid/egid in the workers (also chowns logs):
+# user "unprivileged_user", "unprivileged_group"
+
+# Help ensure your application will always spawn in the symlinked
+# "current" directory that Capistrano sets up.
+# working_directory "/path/to/app/current" # available in 0.94.0+
+
+# listen on both a Unix domain socket and a TCP port,
+# we use a shorter backlog for quicker failover when busy
+# listen "/tmp/.sock", :backlog => 64
+# listen 8080, :tcp_nopush => true
+
+# nuke workers after 30 seconds instead of 60 seconds (the default)
+timeout 30
+
+# feel free to point this anywhere accessible on the filesystem
+# pid "/path/to/app/shared/pids/unicorn.pid"
+
+# By default, the Unicorn logger will write to stderr.
+# Additionally, ome applications/frameworks log to stderr or stdout,
+# so prevent them from going to /dev/null when daemonized here:
+# stderr_path "/path/to/app/shared/log/unicorn.stderr.log"
+# stdout_path "/path/to/app/shared/log/unicorn.stdout.log"
+
+# combine Ruby 2.0.0dev or REE with "preload_app true" for memory savings

+preload_app true
+# GC.respond_to?(:copy_on_write_friendly=) and
+# GC.copy_on_write_friendly = true
+
+# Enable this flag to have unicorn test client connections by writing the
+# beginning of the HTTP headers before calling the application. This
+# prevents calling the application for connections that have disconnected
+# while queued. This is only guaranteed to detect clients on the same
+# host unicorn runs on, and unlikely to detect disconnects even on a
+# fast LAN.

+ # the following is highly recomended for Rails + "preload_app true"
+ # as there's no need for the master process to hold a connection
+ # defined?(ActiveRecord::Base) and
+ # ActiveRecord::Base.connection.disconnect!
+
+ # The following is only recommended for memory/DB-constrained
+ # installations. It is not needed if your system can house
+ # twice as many worker_processes as you have configured.
+ #
+ # # This allows a new master process to incrementally
+ # # phase out the old master process with SIGTTOU to avoid a
+ # # thundering herd (especially in the "preload_app false" case)
+ # # when doing a transparent upgrade. The last worker spawned
+ # # will then kill off the old master process with a SIGQUIT.
+ # old_pid = "#{server.config[:pid]}.oldbin"
+ # if old_pid != server.pid
+ # begin
+ # sig = (worker.nr + 1) >= server.worker_processes ? :QUIT : :TTOU
+ # Process.kill(sig, File.read(old_pid).to_i)
+ # rescue Errno::ENOENT, Errno::ESRCH
+ # end
+ # end
+ #
+ # Throttle the master from forking too quickly by sleeping. Due
+ # to the implementation of standard Unix signal handlers, this
+ # helps (but does not completely) prevent identical, repeated signals
+ # from being lost when the receiving process is busy.
+ # sleep 1

+ # addr = "127.0.0.1:#{9293 + worker.nr}"

+
+ # the following is *required* for Rails + "preload_app true",
+ defined?(ActiveRecord::Base) and
+ ActiveRecord::Base.establish_connection
+
+ # if preload_app is true, then you may also want to check and
+ # restart any other shared sockets/descriptors such as Memcached,
