NAME

FCGI::ProcManager::MaxRequests - restrict max number of requests by each child

SYNOPSIS

Usage same as FCGI::ProcManager:

    use CGI::Fast;
    use FCGI::ProcManager::MaxRequests;

    my $m = FCGI::ProcManager::MaxRequests->new({
        n_processes => 10,
        max_requests => 100,
    });
    $m->manage;

    while( my $cgi = CGI::Fast->new() ) {
        $m->pm_pre_dispatch();
        ...
        $m->pm_post_dispatch();
    }

DESCRIPTION

FCGI-ProcManager-MaxRequests is a extension of FCGI-ProcManager that allow restrict fastcgi processes to process only limiting number of requests. This may help avoid growing memory usage and compensate memory leaks.

This module subclass FCGI::ProcManager. After server process max_requests number of requests, it simple exit, and manager starts another server process. Maximum number of requests can be set from PM_MAX_REQUESTS environment variable, max_requests - constructor argument and max_requests accessor.

OVERLOADED METHODS

new

    my $pm = FCGI::ProcManager::MaxRequests->new(\%args);

Constructs new proc manager object.

max_requests

    $pm->max_requests($max_requests);
    my $max_requests = $pm->max_requests;

Set/get current max_requests value.

handling_init

Initialize requests counter after new worker process forks.

pm_post_dispatch

Do all work. Decrements requests counter after each request and exit worker when needed.

USING WITH CATALYST

At this time, Catalyst::Engine::FastCGI do not allow set any args to FCGI::ProcManager subclass constructor. Because of this we should use environment PM_MAX_REQUESTS ;-)

    PM_MAX_REQUESTS=100 ./script/myapp_fastcgi.pl -n 10 -l <host>:<port> -d -M FCGI::ProcManager::MaxRequests
