=head1 NAME

Net::FCP - http://freenet.sf.net client protocol

=head1 SYNOPSIS

 use Net::FCP;

 my $fcp = new Net::FCP;

 my $ni = $fcp->txn_node_info->result;
 my $ni = $fcp->node_info;

=head1 DESCRIPTION

See L<http://freenet.sourceforge.net/index.php?page=fcp> for a description
of what the messages do. I am too lazy to document all this here.

=head1 WARNING

This module is alpha. While it probably won't destroy (much :) of your
data, it currently falls short of what it should provide (intelligent uri
following, splitfile downloads, healing...)

=head2 IMPORT TAGS

Nothing much can be "imported" from this module right now. There are,
however, certain "import tags" that can be used to select the event model
to be used.

Event models are implemented as modules under the C<Net::FCP::Event::xyz>
class, where C<xyz> is the event model to use. The default is C<Event> (or
later C<Auto>).

The import tag to use is named C<event=xyz>, e.g. C<event=Event>,
C<event=Glib> etc.

You should specify the event module to use only in the main program.

If no event model has been specified, FCP tries to autodetect it on first
use (e.g. first transaction), in this order: Coro, Event, Glib, Tk.

=head2 FREENET BASICS

Ok, this section will not explain any freenet basics to you, just some
problems I found that you might want to avoid:

=over 4

=item freenet URIs are _NOT_ URIs

Whenever a "uri" is required by the protocol, freenet expects a kind of
URI prefixed with the "freenet:" scheme, e.g. "freenet:CHK...". However,
these are not URIs, as freeent fails to parse them correctly, that is, you
must unescape an escaped characters ("%2c" => ",") yourself. Maybe in the
future this library will do it for you, so watch out for this incompatible
change.

=item Numbers are in HEX

Virtually every number in the FCP protocol is in hex. Be sure to use
C<hex()> on all such numbers, as the module (currently) does nothing to
convert these for you.

=item $meta = Net::FCP::parse_metadata $string

Parse a metadata string and return it.

The metadata will be a hashref with key C<version> (containing the
mandatory version header entries) and key C<raw> containing the original
metadata string.

All other headers are represented by arrayrefs (they can be repeated).

Since this description is confusing, here is a rather verbose example of a
parsed manifest:

   (
      raw => "Version...",
      version => { revision => 1 },
      document => [
                    {

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

Create a new virtual FCP connection to the given host and port (default
127.0.0.1:8481, or the environment variables C<FREDHOST> and C<FREDPORT>).

Connections are virtual because no persistent physical connection is
established.

You can install a progress callback that is being called with the Net::FCP
object, a txn object, the type of the transaction and the attributes. Use
it like this:

   sub progress_cb {
      my ($self, $txn, $type, $attr) = @_;

      warn "progress<$txn,$type," . (join ":", %$attr) . ">\n";
   }

=begin comment

However, the existance of the node is checked by executing a
C<ClientHello> transaction.

=item $txn = $fcp->txn(type => attr => val,...)

The low-level interface to transactions. Don't use it.

Here are some examples of using transactions:

The blocking case, no (visible) transactions involved:

   my $nodehello = $fcp->client_hello;

A transaction used in a blocking fashion:
   
   my $txn = $fcp->txn_client_hello;
   ...
   my $nodehello = $txn->result;

Or shorter:

   my $nodehello = $fcp->txn_client_hello->result;

Setting callbacks:

   $fcp->txn_client_hello->cb(
      sub { my $nodehello => $_[0]->result }
   );

Inserts a private key. $private can be either an insert URI (must start
with C<freenet:SSK@>) or a raw private key (i.e. the private value you get
back from C<generate_svk_pair>).

Returns the public key.

Fetches a (small, as it should fit into memory) file from
freenet. C<$meta> is the metadata (as returned by C<parse_metadata> or
C<undef>).

The C<$uri> should begin with C<freenet:>, but the scheme is currently
added, if missing.

Due to the overhead, a better method to download big files should be used.

=item my $uri = $fcp->client_put ($uri, $metadata, $data, $htl, $removelocal);

Insert a new key. If the client is inserting a CHK, the URI may be
abbreviated as just CHK@. In this case, the node will calculate the
CHK.

C<$meta> can be a reference or a string (ONLY THE STRING CASE IS IMPLEMENTED!).

=head2 THE Net::FCP::Txn CLASS

All requests (or transactions) are executed in a asynchronous way. For
each request, a C<Net::FCP::Txn> object is created (worse: a tcp
connection is created, too).

For each request there is actually a different subclass (and it's possible
to subclass these, although of course not documented).

The most interesting method is C<result>.

Sets a callback to be called when the request is finished. The coderef

C<result> itself.

Waits until a result is available and then returns it.

This waiting is (depending on your event model) not very efficient, as it
is done outside the "mainloop". The biggest problem, however, is that it's
blocking one thread of execution. Try to use the callback mechanism, if
possible, and call result from within the callback (or after is has been
run), as then no waiting is necessary.

=head2 The Net::FCP::Exception CLASS

Any unexpected (non-standard) responses that make it impossible to return
the advertised result will result in an exception being thrown when the
C<result> method is called.

These exceptions are represented by objects of this class.

package Net::FCP::Exception;

use overload
   '""' => sub {
      "Net::FCP::Exception<<$_[0][0]," . (join ":", %{$_[0][1]}) . ">>";
   };

=item $exc = new Net::FCP::Exception $type, \%attr

Create a new exception object of the given type (a string like
C<route_not_found>), and a hashref containing additional attributes
(usually the attributes of the message causing the exception).

=cut

sub new {
   my ($class, $type, $attr) = @_;

   bless [Net::FCP::tolc $type, { %$attr }], $class;
}

=item $exc->type([$type])

With no arguments, returns the exception type. Otherwise a boolean
indicating wether the exception is of the given type is returned.

=cut

sub type {
   my ($self, $type) = @_;

   @_ >= 2
      ? $self->[0] eq $type
      : $self->[0];
}

=item $exc->attr([$attr])

With no arguments, returns the attributes. Otherwise the named attribute
value is returned.

=cut

sub attr {
   my ($self, $attr) = @_;

   @_ >= 2
      ? $self->[1]{$attr}
