Modern concurrency tools including agents, futures, promises, thread pools, actors, supervisors, and more. Inspired by Erlang, Clojure, Go, JavaScript, actors, and classic concurrency patterns.

A collection of data structures and utilities to make thread-safe programming in Ruby easier

Puma is a simple, fast, multi-threaded, and highly parallel HTTP 1.1 server for Ruby/Rack applications. Puma is intended for use in both development and production environments. It's great for highly parallel Ruby implementations such as JRuby and TruffleRuby as well as as providing process worke...

EventMachine implements a fast, single-threaded engine for arbitrary network communications. It's extremely easy to use in Ruby. EventMachine wraps all interactions with IP sockets, allowing programs to concentrate on the implementation of network protocols. It can be used to create both network ...

Manages persistent connections using Net::HTTP including a thread pool for connecting to multiple hosts. Using persistent HTTP connections can dramatically increase the speed of HTTP. Creating a new HTTP connection for every request involves an extra TCP round-trip and causes TCP congestion avoi...

You probably meant `gem install thread_safe`.

Efficient, immutable, thread-safe collection classes for Ruby

Ruby bindings to RE2, "a fast, safe, thread-friendly alternative to backtracking regular expression engines like those used in PCRE, Perl, and Python".

A simple, fast, memory-efficient and threadsafe implementation of GetText

Shoryuken is a super efficient AWS SQS thread based message processor

ThreadParent facilitates spawning threads that maintain a reference to the thread that created them. The primary goal is to allow thread local variable lookup through the ancestor chain.

Setup signal handler which dumps backtrace of running threads and number of allocated objects per class. Require 'sigdump/setup', send SIGCONT, and see /tmp/sigdump-<pid>.log.

Thread-safety checks via static analysis. A plugin for the RuboCop code style enforcing & linting tool.

Polymorphic threaded comments Rails gem for Rails 4+

Efficient and thread-safe LRU cache

Memoize attributes in a thread-safe way. This ruby gem adds a `#attr_memoized` class method, that provides a lazy-loading mechanism for initializing "heavy" attributes, but in a thread-safe way. Instances thus created can be shared among threads.

Implements a thread based worker pattern on top of JRuby-Rack. Useful if you'd like to run background workers within your (deployed) web-application, concurrently in 'native' threads, instead of using separate daemon processes. Provides (thread-safe) implementations for popular worker libraries s...

Emulates Python threading API paradigm. Creating threads by giving some block to constructor is sometime slightly unpractical way of running threads. This library allows encapsulating threads to classes, so class can define itself as thread which can be run by plain method call.

LazyData provides data types featuring thread-safe lazy computation. These objects are constructed with a block that can be called to compute the final value, but it is not actually called until the value is requested. Once requested, the computation takes place only once, in the first thread tha...

Passes thread variables to child spawned threads. Main use case is enabling logging in child thread to keep context of a request.
