Build Status

About

The libasync asynchronous library is written completely in D, features a cross-platform event loop and enhanced connectivity and concurrency facilities for extremely lightweight asynchronous tasks. It embeds naturally to D projects (DMD >= 2.067.0, LDC >= 0.15.1), compiles statically with your project and has an open source license (MIT).

A fully functional, tested vibe.d driver is available in the latest version of vibe.d, you can enable it by appending "subConfigurations": { "vibe-d": "libasync"} in your project's dub.json configuration file.

Features

The following capabilities are now being tested and should not be used in any circumstance in a production environment.

(*) Unit tests confirmed on Mac, Linux, Windows - Platforms used were Mac OS X (10.8, 10.9), Linux (Fedora 20+) and Windows 32/64 bit, although it should be compatible to 99% of Desktop OS users.

(*) Compiles with DMD & LDC (DMD 2.067.0, 2.067.1, LDC 0.15.1)

  • Multi-threading support - EventLoop can be launched and run from an unlimited number of threads!

  • Asynchronous TCP connection - handles multiple requests at a time in each individual thread

  • Buffered TCP connection - Allows callbacks to be attached to a byte sized future

  • Asynchronous TCP listener - delivers a new connection to the delegate of your choice

  • File Operations - executes file read/write/append commands in a thread pool, notifies of completion in a handler

  • DNS resolver - runs blocking DNS resolve operations in a thread pool, savings are the duration of a ping.

  • File/Folder Watcher - watches directories for file changes (CREATE, DELETE, MODIFY, RENAME/MOVE)

  • UDP connection - receives or sends packets from/to multiple peers

  • Timer - sets a periodic or one-shot/periodic timer with high-precision (μs) to call a select delegate

  • Signal - Wakes up the event loop in a foreign thread and passes a message to its delegate

  • Notifier - Thread-local and lock-less adaptation of Signal which queues a message intended for a local delegate

Limitations

Some or all of these limitations are possibly being implemented currently and may be available in a future release.

  • One EventLoop per thread - There is a hard limit of one event loop per thread
  • Manual error management - The entire library is nothrow and error management must be built on top of it.
  • No embedded HTTP or TLS handlers - The support fort HTTP, TLS (and other protocols) is only available through vibe.d with Tasks as of yet.

Installation Instructions

  • Download and install DMD 2.067.0+ from dlang.org
  • Download and install dub 0.9.22+ from code.dlang.org
  • Use Git to clone this repository
  • Run dub test to test the library on your operating system (submit any issue with a log report by uncommenting enum LOG = true in types.d)
  • Add the library to your project by including it in the dependencies, using import libasync
  • The recommended editor is MonoDevelop with Mono-D due to its Mixin Template resolver (must be enabled manually), with auto-completion and comment-resolved summary tooltips.
  • On another note, you can also try the vibe.d libasync built-in driver by adding "subConfigurations": { "vibe-d": "libasync" } to your vibe.d dub.json.

Tutorial

There are 4 examples available at the moment, they are located in examples/. They must be tested by starting the server before the client.

All other usage examples are available in source/libasync/test.d.

Documentation has been written throughout the code.
