POE::Component::Daemon

POE::Component::Daemon is an efficient Perl module that relieves the tedious task of handling all the details involved in the creation and maintenance of daemon processes. You can detach from the console, pool or post-forking, and even redirect STDERR to a log file with ease. The module also babysits child processes and ensures that requests don't take too long.

It is important to note that POE::Component::Daemon does not handle listening on sockets, but it is up to your code. As with all POE modules, POE::Component::Daemon works cooperatively, meaning that it is your responsibility to let the module know when to fork, block incoming requests, and so on. Sub-processes are efficiently maintained with the help of a scoreboard, and in some situations, it's advisable to update the status in the scoreboard with the "update_status" method.

To get started using POE::Component::Daemon, you can easily spawn it with the desired configurations, such as detach and max_children. You can also create a session that uses SocketFactory, handle the connection, the child process, and even mark the requests that will take long with the module's update_status. The module is easy to use and provides a great deal of convenience and automation in handling daemon processes.
