historique

Historique du projet et usages

c-ares is an MIT-licensed C library for asynchronous DNS resolution. It grew out of Daniel Stenberg's search for a non-blocking resolver suitable for libcurl and became a long-lived dependency for network software that cannot afford blocking name lookups.

Historique du projet

The official `why` page explains that Daniel Stenberg looked for an asynchronous DNS resolver for libcurl, found the older ares library, began expanding it, and forked when the original author would not accept the needed changes. That fork became c-ares.

The project still acknowledges ares as the public API influence while noting that the code no longer closely resembles the original. Its README now describes c-ares as a modern DNS stub resolver written in C with asynchronous interfaces, portability across Unix, Windows, mobile, and other systems, and active maintenance after more than 20 years.

Recent project materials emphasize security practice as much as asynchronous lookup: safe parsers and builders, static and dynamic analysis, OSS-Fuzz coverage, signed releases, and SLSA provenance for release artifacts.

Historique d'adoption

c-ares adoption started from libcurl's need for DNS lookups that could integrate with event-driven network code. From there it spread into software that needs many DNS queries in parallel or wants resolver behavior independent from a platform's blocking libc calls.

Its package-manager footprint is broad: Homebrew, Debian and Ubuntu development packages, Fedora, Alpine, Arch, MacPorts, Nix, and openSUSE all package it. That breadth reflects its status as a library dependency more than an end-user command, although tools such as `adig` and `ahost` are installed with some packages.

Modes d'utilisation

Developers link against c-ares to issue asynchronous DNS queries through non-blocking sockets and integrate DNS work into event loops. The official docs include initialization APIs such as `ares_init_options` and resolver configuration behavior.

On Unix-like systems c-ares reads resolver environment from standard system files such as `/etc/resolv.conf` and `/etc/hosts`, matching the package's curated config-file locations.

Pourquoi les passionnés de paquets s'y intéressent

c-ares is one of those packages users may never invoke directly but build systems constantly care about. It is a small C library whose ABI, headers, pkg-config metadata, and security updates affect curl-like networking stacks across distributions.

For package nerds, it is also a clean example of a library fork becoming infrastructure: born from a specific libcurl need, preserved for API/ABI stability, and now maintained with modern supply-chain signals such as signed releases and SLSA provenance.

Chronologie

  • Early 2000s: Daniel Stenberg searches for an asynchronous DNS resolver for libcurl and forks from ares to create c-ares.
  • 2004: Early tags such as `c-ares-1_2_0` appear in the upstream repository history.
  • 2010s: c-ares remains a common packaged dependency for asynchronous DNS in C networking software.
  • 2024: The project site describes more than 20 years of active maintenance and modern DNS RFC support.
  • 2025: The official site publishes c-ares 1.34.6 as a signed release with release provenance.

Related projects

  • libcurl is the motivating user described by the official history page.
  • ares is the older resolver library from which c-ares forked.
  • ADNS, UDNS, FireDNS, Mozilla netlib, djbdns, and other resolver libraries are discussed by the c-ares project as alternatives or contemporaries.
