NAME

HTTP::Server::EV - Asynchronous HTTP server written in C with request parser.

DESCRIPTION

HTTP::Server::EV - Asynchronous HTTP server using EV event loop. It doesn`t load files received in the POST request in memory as moust of CGI modules does, but stores them directly to tmp files, so it`s useful for handling large files without using a lot of memory.

INCLUDED MODULES

HTTP::Server::EV::CGI - received http request object HTTP::Server::EV::MultipartFile - received file object HTTP::Server::EV::Buffer - non blocking output HTTP::Server::EV::BufTie - workaround for correct handling requests in Coro threads

SYNOPSIS

        use EV;
        use HTTP::Server::EV;
        my $server = HTTP::Server::EV->new;
        
        $server->listen(90, sub {
                my $cgi = shift;
                
                $cgi->attach(*STDOUT);
                $cgi->header;

                print "Just another Perl server\n";
        });
        EV::loop;

METHODS

new( { options } )

Options:

tmp_path

Directory for saving received files. Tries to create if not found, dies on fail. Default: ./upload_tmpfiles/

cleanup_on_destroy

Usually HTTP::Server::EV::CGI deletes tmp files on DESTROY, but it might by bug if you delete HTTP::Server::EV::CGI object when its files are still opened. Setting on this flag causes HTTP::Server::EV delete all files in tmp_path on program close, but don`t use it if jou have several process working with same tmp dir. Default: 0

backend

Seting on cause HTTP::Server::EV::CGI parse ip from X-Real-IP http header Default: 0

listen( port , sub {callback} )

Binds callback to port. Calls callback and passes HTTP::Server::EV::CGI object in it;

        $server->listen( 8080 , sub {
                my $cgi = shift;
                
                $cgi->attach(local *STDOUT); # attach STDOUT to socket
                
                $cgi->header; # print http headers to stdout
                
                print "Test page";
        });

cleanup

Delete all files in tmp_path. Automatically called on DESTROY if cleanup_on_destroy set

TODO

Write tests

Write request parser error handling - Server drops connection on error(Malformed or too large request), but there is no way to know what error happened.

unbind function

BUGS/WARNINGS

You can`t create two HTTP::Server::EV objects at same process.

Static allocated buffers:

- Can`t listen more than 20 ports at same time

- 4kb for GET/POST form field names

- 4kb for GET values

- 50kb for POST form field values ( not for files. Files are stored into tmp directly from socket stream, so filesize not limited by HTTP::Server::EV)

HTTP::Server::EV drops connection if some buffer overflows. You can change these values in EV.xs and recompile module.
