#!/usr/bin/env puma

# The directory to operate out of.
#
# The default is the current directory.
#
# directory '/u/apps/lolcat'

# Use an object or block as the rack application. This allows the
# config file to be the application itself.
#
# app do |env|
#   puts env
#
#   body = 'Hello, World!'
#
#   [200, { 'Content-Type' => 'text/plain', 'Content-Length' => body.length.to_s }, [body]]
# end

# Load "path" as a rackup file.
#
# The default is "config.ru".
#
# rackup '/u/apps/lolcat/config.ru'

# Set the environment in which the rack's app will run. The value must be a string.
#
# The default is "development".
#
# environment 'production'

# Daemonize the server into the background. Highly suggest that
# this be combined with "pidfile" and "stdout_redirect".
#
# The default is "false".
#
# daemonize
# daemonize false

# Store the pid of the server in the file at "path".
#
# pidfile '/u/apps/lolcat/tmp/pids/puma.pid'

# Use "path" as the file to store the server info state. This is
# used by "pumactl" to query and control the server.
#
# state_path '/u/apps/lolcat/tmp/pids/puma.state'

# Redirect STDOUT and STDERR to files specified. The 3rd parameter
# ("append") specifies whether the output is appended, the default is
# "false".
#
# stdout_redirect '/u/apps/lolcat/log/stdout', '/u/apps/lolcat/log/stderr'
# stdout_redirect '/u/apps/lolcat/log/stdout', '/u/apps/lolcat/log/stderr', true

# Disable request logging.
#
# The default is "false".
#
# quiet

# Configure "min" to be the minimum number of threads to use to answer
# requests and "max" the maximum.
#
# The default is "0, 16".
#
# threads 0, 16

# Bind the server to "url". "tcp://", "unix://" and "ssl://" are the only
# accepted protocols.
#
# The default is "tcp://0.0.0.0:9292".
#

# can also use the "ssl_bind" option.

# Code to run before doing a restart. This code should
# close log files, database connections, etc.
#
# This can be called multiple times to add code each time.

# Command to use to restart puma. This should be just how to
# load puma itself (ie. 'ruby -Ilib bin/puma'), not the arguments
# to puma, as those are the same as the original process.
#
# restart_command '/u/app/lolcat/bin/restart_puma'

# === Cluster mode ===

# How many worker processes to run.
#
# The default is "0".
#
# workers 2

# Code to run when a worker boots to setup the process before booting
# the app.
#
# This can be called multiple times to add hooks.
#
# on_worker_boot do

# Code to run when a worker boots to setup the process after booting
# the app.
#
# This can be called multiple times to add hooks.

# Code to run when a worker shutdown.
#
#
# on_worker_shutdown do
#   puts 'On worker shutdown...'
# end

# Allow workers to reload bundler context when master process is issued
# a USR1 signal. This allows proper reloading of gems while the master
# is preserved across a phased-restart. (incompatible with preload_app)
# (off by default)

# prune_bundler

# Preload the application before starting the workers; this conflicts with
# phased restart feature. (off by default)

# preload_app!

# Additional text to display in process listing
#
# tag 'app name'

# Change the default timeout of workers
#
# worker_timeout 60

# === Puma control rack application ===

# Start the puma control rack application on "url". This application can
# be communicated with to control the main server. Additionally, you can
# provide an authentication token, so all requests to the control server
# will need to include that token as a query parameter. This allows for
# simple authentication.
#
# Check out https://github.com/puma/puma/blob/master/lib/puma/app/status.rb
# to see what the app has available.
#
# activate_control_app 'unix:///var/run/pumactl.sock'
# activate_control_app 'unix:///var/run/pumactl.sock', { auth_token: '12345' }
# activate_control_app 'unix:///var/run/pumactl.sock', { no_token: true }
