# Puma can serve each request in a thread from an internal thread pool.

# The `threads` method setting takes two numbers: a minimum and maximum.

# Any libraries that use thread pools should be configured to match

# the maximum value specified for Puma. Default is set to 5 threads for minimum

# and maximum; this matches the default thread size of Active Record.

#

threads_count = ENV.fetch("RAILS_MAX_THREADS") { 5 }

threads threads_count, threads_count

# Specifies the `port` that Puma will listen on to receive requests; default is 3000.

#

port ENV.fetch("PORT") { 3000 }

# Specifies the `environment` that Puma will run in.

#

environment ENV.fetch("RAILS_ENV") { "development" }

# Specifies the number of `workers` to boot in clustered mode.

# Workers are forked webserver processes. If using threads and workers together

# the concurrency of the application would be max `threads` * `workers`.

# Workers do not work on JRuby or Windows (both of which do not support

# processes).

#

# workers ENV.fetch("WEB_CONCURRENCY") { 2 }

# Use the `preload_app!` method when specifying a `workers` number.

# This directive tells Puma to first boot the application and load code

# before forking the application. This takes advantage of Copy On Write

# process behavior so workers use less memory. If you use this option

# you need to make sure to reconnect any threads in the `on_worker_boot`

# block.

#

# preload_app!

# If you are preloading your application and using Active Record, it's

# recommended that you close any connections to the database before workers

# are forked to prevent connection leakage.

#

# before_fork do

# ActiveRecord::Base.connection_pool.disconnect! if defined?(ActiveRecord)

# end

# The code in the `on_worker_boot` will be called if you are using

# clustered mode by specifying a number of `workers`. After each worker

# process is booted, this block will be run. If you are using the `preload_app!`

# option, you will want to use this block to reconnect to any threads

# or connections that may have been created at application boot, as Ruby

# cannot share connections between processes.

#

# on_worker_boot do

# ActiveRecord::Base.establish_connection if defined?(ActiveRecord)

# end

#

# Allow puma to be restarted by `rails restart` command.
