libserver-starter-perl - 0.35-2 main

It is often a pain to write a server program that supports graceful restarts,
with no resource leaks. Server::Starter solves the problem by splitting the
task into two. One is start_server, a script provided as a part of the module,
which works as a superdaemon that binds to zero or more TCP ports or unix
sockets, and repeatedly spawns the server program that actually handles the
necessary tasks (for example, responding to incoming commenctions). The spawned
server programs under Server::Starter call accept(2) and handle the requests.
.
To gracefully restart the server program, send SIGHUP to the superdaemon. The
superdaemon spawns a new server program, and if (and only if) it starts up
successfully, sends SIGTERM to the old server program.
