simplepool

Simple thread-safe pool for anything that is not thread-safe.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     simplepool:
       github: konovod/simplepool
   

2. Run shards install

Usage

require "simplepool"
# Note that `MyConnection.new` will be protected by mutex, so can be not thread-safe
pool = SimplePool(MyConnection).new { MyConnection.new(address, port) }
10.times do
  spawn do
    # get object from pool
    conn = pool.get
    work_with(conn)
    # don't forget to return it
    pool.return(conn)
  end
end
10.times do
  spawn do
    # safe version as you don't need to explicitely return it
    pool.use do |conn|
      work_with conn
      raise "error" # object will be returned to pool even after raise
    end
  end
end
