net::server::fork
Net::Server::Fork(3) User Contributed Perl Documentation Net::Server::Fork(3)NAME
Net::Server::Fork - Net::Server personality
SYNOPSIS
use Net::Server::Fork;
@ISA = qw(Net::Server::Fork);
sub process_request {
#...code...
}
__PACKAGE__->run();
DESCRIPTION
Please read the pod on Net::Server first. This module is a personality, or extension, or sub class, of the Net::Server module.
This personality binds to one or more ports and then waits for a client connection. When a connection is received, the server forks a
child. The child handles the request and then closes.
With the exception of parent/child signaling, this module will work (with basic functionality) on Win32 systems.
ARGUMENTS
check_for_dead
Number of seconds to wait before looking for dead children. This only takes place if the maximum number of child processes
(max_servers) has been reached. Default is 60 seconds.
max_servers
The maximum number of children to fork. The server will not accept connections until there are free children. Default is 256 children.
max_dequeue
The maximum number of dequeue processes to start. If a value of zero or undef is given, no dequeue processes will be started. The
number of running dequeue processes will be checked by the check_for_dead variable.
check_for_dequeue
Seconds to wait before forking off a dequeue process. It is intended to use the dequeue process to take care of items such as mail
queues. If a value of undef is given, no dequeue processes will be started.
CONFIGURATION FILE
See Net::Server.
PROCESS FLOW
Process flow follows Net::Server until the post_accept phase. At this point a child is forked. The parent is immediately able to wait for
another request. The child handles the request and then exits.
HOOKS
The Fork server has the following hooks in addition to the hooks provided by the Net::Server base class. See Net::Server
"$self->pre_accept_hook()"
This hook occurs just before the accept is called.
"$self->pre_fork_hook()"
This hook occurs just after accept but before the fork.
"$self->post_accept_hook()"
This hook occurs in the child after the accept and fork.
"$self->run_dequeue()"
This hook only gets called in conjuction with the check_for_dequeue setting.
TO DO
See Net::Server
