# TAKE A LOOK AT THIS BEFORE DEPLOYING ->>> http://unicorn.bogomips.org/Unicorn/Configurator.html
# 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 "/path/to/.unicorn.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 2.0.0+ with "preload_app true" for memory savings
# preload_app 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.
# check_client_connection false

# local variable to guard against running a hook multiple times
# run_once = true

# before_fork do |server, worker|
#   # 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) && ActiveRecord::Base.connection.disconnect!

#   # Occasionally, it may be necessary to run non-idempotent code in the
#   # master before forking.  Keep in mind the above disconnect! example
#   # is idempotent and does not need a guard.
#   if run_once
#     # do_something_once_here ...
#     run_once = false # prevent from firing again
#   end

#   # 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
# end

# after_fork do |server, worker|
#   # per-process listener ports for debugging/admin/migrations
#   # addr = "127.0.0.1:#{9293 + worker.nr}"
#   # server.listen(addr, :tries => -1, :delay => 5, :tcp_nopush => true)

#   # the following is *required* for Rails + "preload_app true",
#   defined?(ActiveRecord::Base) && 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,
#   # and Redis.  TokyoCabinet file handles are safe to reuse
#   # between any number of forked children (assuming your kernel
#   # correctly implements pread()/pwrite() system calls)
