Threadsafe (Inactive, code moved to concurrent-ruby gem and repo.)

A collection of thread-safe versions of common core Ruby classes.

This code base is now part of the concurrent-ruby gem at https://github.com/ruby-concurrency/concurrent-ruby. The code in this repository is no longer maintained.

Installation

Add this line to your application's Gemfile:

gem 'thread_safe'

And then execute:

$ bundle

Or install it yourself as:

$ gem install thread_safe

Usage

require 'thread_safe'

sa = ThreadSafe::Array.new # supports standard Array.new forms
sh = ThreadSafe::Hash.new # supports standard Hash.new forms

ThreadSafe::Cache also exists, as a hash-like object, and should have much better performance characteristics esp. under high concurrency than ThreadSafe::Hash. However, ThreadSafe::Cache is not strictly semantically equivalent to a ruby Hash -- for instance, it does not necessarily retain ordering by insertion time as Hash does. For most uses it should do fine though, and we recommend you consider ThreadSafe::Cache instead of ThreadSafe::Hash for your concurrency-safe hash needs. It understands some options when created (depending on your ruby platform) that control some of the internals - when unsure just leave them out:

require 'thread_safe'

cache = ThreadSafe::Cache.new
