履歴

プロジェクトの歴史と使われ方

libevent is a portable C event-notification library for scalable network servers and event-driven programs.

プロジェクトの歴史

The libevent site describes the library as a replacement for hand-written event loops in network servers: programs register callbacks for file-descriptor readiness, timers, signals, and higher-level buffered I/O rather than hard-coding select or poll loops. The site credits maintenance to Nick Mathewson, Azat Khuzhin, and Niels Provos.

The project grew around the C10K-era problem of serving many simultaneous connections portably across backends such as select, poll, epoll, kqueue, /dev/poll, Solaris event ports, and Windows APIs. Over time it added buffered network I/O, DNS, HTTP, RPC, SSL-capable bufferevents, thread hooks, and extensive portability code.

採用の歴史

The official site lists widely used downstreams including Chromium, memcached, Transmission, NTP's SNTP code, tmux, Tor, Prosody, PgBouncer, and coturn. That breadth made libevent one of the standard C event-loop dependencies in Unix package collections.

使われ方

Typical applications create an event_base, register events or bufferevents, and run event_base_dispatch. The official documentation covers setup, event bases, timers, buffered I/O, asynchronous DNS, embedded HTTP servers, and RPC support.

パッケージ好きにとっての重要性

libevent is package-nerd-famous because it abstracts the messy portability matrix behind scalable C networking. It is old enough to show up in classic daemons and new enough to have ABI/API reports, split libraries, CMake and autotools history, and long-lived 1.4, 2.0, and 2.1 release lines.
