Description

Happy eyeballs is an implementation of RFC 8305 which specifies how to connect to a remote host using either IP protocol version 4 or IP protocol version 6. This uses Lwt and Mirage for side effects.

Published: 16 Jun 2023

README

happy eyeballs -- connecting to a remote host

RFC 8305 describes how to connect to a remote host, given that the host may have multiple addresses (IPv4 and IPv6, via DNS A and AAAA resource records), and the local host may have connectivity via IPv4 only, IPv6 only, or both. The preference is to use IPv6.

This package implements the given RFC in its core (Happy_eyeballs module). In addition, the Happy_eyeballs_lwt is a Lwt implementation using Unix.

The implemented state machine is kept in-sync with the code (source: happy_eyeballs.dot at the root of this repository).

It is licensed under the ISC license.

Installation

opam install happy-eyeballs happy-eyeballs-lwt happy-eyeballs-mirage

Development

Since dns-client depends on happy-eyeballs and happy-eyeballs-lwt, happy-eyeballs-mirage depend on dns-client, the dune build system is easily confused. A workaround is after a git clone of happy-eyeballs, do an opam source dns-client. Then dune will use the local dns-client package, and there will be no circularity issue.
