This code is still pretty early, and not yet used in production. That said, I am interested in feedback. You can send me a message on GitHub’s internal messaging system (github.com/inbox/new/fizx).

A simple executor-style ThreadPool for Ruby (with tests, yay!)

Usage:

require “rubygems” require “thread_pool” pool = ThreadPool.new(threads = 10) pool.execute { puts “I’m writing from a thread” } pool.join It’s often useful to make sure that the properties of Ruby’s blocks don’t bite you. The following code will usually print three nils, because n keeps changing.

pool = ThreadPool.new(threads = 10) numbers = [1, 2, 3] while n = numbers.shift pool.execute { puts n.inspect } end pool.join Passing arguments to execute avoids this. i.e.:

pool = ThreadPool.new(threads = 10) numbers = [1, 2, 3] while n = numbers.shift pool.execute(n) {|local| puts local.inspect } end pool.join
