NAME

AnyEvent::FCP - freenet client protocol 2.0

SYNOPSIS

use AnyEvent::FCP;

my $fcp = new AnyEvent::FCP;

# transactions return condvars my $lp_cv = $fcp->list_peers; my $pr_cv = $fcp->list_persistent_requests;

my $peers = $lp_cv->recv;
my $reqs  = $pr_cv->recv;

DESCRIPTION

This module implements the freenet client protocol version 2.0, as used by freenet 0.7. See Net::FCP for the earlier freenet 0.5 version.

See http://wiki.freenetproject.org/FreenetFCPSpec2Point0 for a description of what the messages do.

The module uses AnyEvent to find a suitable event module.

Only very little is implemented, ask if you need more, and look at the example program later in this section.

IMPORT TAGS

Nothing much can be "imported" from this module right now.

THE AnyEvent::FCP CLASS

$fcp = new AnyEvent::FCP [host => $host][, port => $port][, progress => \&cb][, name => $name]

Create a new FCP connection to the given host and port (default 127.0.0.1:9481, or the environment variables FREDHOST and FREDPORT).

If no name was specified, then AnyEvent::FCP will generate a (hopefully) unique client name for you.

$cv = $fcp->list_peers ([$with_metdata[, $with_volatile]])

$peers = $fcp->list_peers_sync ([$with_metdata[, $with_volatile]])

$cv = $fcp->list_peer_notes ($node_identifier)

$notes = $fcp->list_peer_notes_sync ($node_identifier)

$cv = $fcp->watch_global ($enabled[, $verbosity_mask])

$fcp->watch_global_sync ($enabled[, $verbosity_mask])

$cv = $fcp->list_persistent_requests

$reqs = $fcp->list_persistent_requests_sync

$cv = $fcp->remove_request ($global, $identifier)

$status = $fcp->remove_request_sync ($global, $identifier)

$cv = $fcp->modify_persistent_request ($global, $identifier[, $client_token[, $priority_class]])

$sync = $fcp->modify_persistent_request_sync ($global, $identifier[, $client_token[, $priority_class]])

$cv = $fcp->get_plugin_info ($name, $detailed)

$info = $fcp->get_plugin_info_sync ($name, $detailed)

$cv = $fcp->client_get ($uri, $identifier, %kv)

$status = $fcp->client_get_sync ($uri, $identifier, %kv)

%kv can contain (http://wiki.freenetproject.org/FCP2p0ClientGet).

EXAMPLE PROGRAM

use AnyEvent::FCP;

my $fcp = new AnyEvent::FCP;

# let us look at the global request list
$fcp->watch_global (1, 0);

# list them, synchronously
my $req = $fcp->list_persistent_requests_sync;

# go through all requests
for my $req (values %$req) {
   # skip jobs not directly-to-disk
   next unless $req->{return_type} eq "disk";
   # skip jobs not issued by FProxy
   next unless $req->{identifier} =~ /^FProxy:/;

   if ($req->{data_found}) {
      # file has been successfully downloaded
      
      ... move the file away
      (left as exercise)

      # remove the request

      $fcp->remove_request (1, $req->{identifier});
   } elsif ($req->{get_failed}) {
      # request has failed
      if ($req->{get_failed}{code} == 11) {
         # too many path components, should restart
      } else {
         # other failure
      }
   } else {
      # modify priorities randomly, to improve download rates
      $fcp->modify_persistent_request (1, $req->{identifier}, undef, int 6 - 5 * (rand) ** 1.7)
         if 0.1 > rand;
   }
}

# see if the dummy plugin is loaded, to ensure all previous requests have finished.
$fcp->get_plugin_info_sync ("dummy");
