## Historique du projet et usages

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

### Historique du projet

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.

### Historique d'adoption

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.

### Modes d'utilisation

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.

### Pourquoi les passionnés de paquets s'y intéressent

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.

### Chronologie

- 2009: Niels Provos announced libevent 1.4.12-stable and libevent 2.0.2-alpha on July 29, 2009.
- 2010: The libevent site lists libevent-1.4.14b-stable released June 7, 2010.
- 2012: The libevent site lists the first 2.1.x alpha release on April 3, 2012 and libevent-2.0.21-stable released November 18, 2012.
- 2014: The libevent site lists libevent-2.0.22-stable released January 5, 2014.
- 2017: The libevent site lists libevent-2.1.8-stable released January 22, 2017.
- 2020: The libevent site lists libevent-2.1.12-stable released July 5, 2020.
- 2023: The libevent site lists libevent-2.2.1-alpha-dev released May 21, 2023.
