12 DESCRIPTION
13 See <http://freenet.sourceforge.net/index.php?page=fcp> for a
14 description of what the messages do. I am too lazy to document all this
15 here.
16
17 WARNING
18 This module is alpha. While it probably won't destroy (much :) of your
19 data, it currently works only with the Event module (alkthough the event
20 mechanism is fully pluggable).
21
22 THE Net::FCP CLASS
23 $fcp = new Net::FCP [host => $host][, port => $port]
24 Create a new virtual FCP connection to the given host and port
25 (default 127.0.0.1:8481).
26
27 Connections are virtual because no persistent physical connection is
28 established. However, the existance of the node is checked by
29 executing a "ClientHello" transaction.
30
31 $txn = $fcp->txn(type => attr => val,...)
32 The low-level interface to transactions. Don't use it.
33
34 $txn = $fcp->txn_client_hello
35 $nodehello = $fcp->client_hello
36 Executes a ClientHello request and returns it's results.
37
38 {
39 max_file_size => "5f5e100",
40 protocol => "1.2",
41 node => "Fred,0.6,1.46,7050"
42 }
43
44 $txn = $fcp->txn_client_info
45 $nodeinfo = $fcp->client_info
46 Executes a ClientInfo request and returns it's results.

70 }
71
72 $txn = $fcp->txn_generate_chk ($metadata, $data)
73 $uri = $fcp->generate_chk ($metadata, $data)
74 Creates a new CHK, given the metadata and data. UNTESTED.
75
76 $txn = $fcp->txn_generate_svk_pair
77 ($public, $private) = @{ $fcp->generate_svk_pair }
78 Creates a new SVK pair. Returns an arrayref.
79
80 [
81 "hKs0-WDQA4pVZyMPKNFsK1zapWY",
82 "ZnmvMITaTXBMFGl4~jrjuyWxOWg"
83 ]
84
85 $txn = $fcp->txn_insert_private_key ($private)
86 $uri = $fcp->insert_private_key ($private)
87 Inserts a private key. $private can be either an insert URI (must
88 start with freenet:SSK@) or a raw private key (i.e. the private
89 value you get back from "generate_svk_pair").
90
91 Returns the public key.
92
93 UNTESTED.
94
95 $txn = $fcp->txn_get_size ($uri)
96 $length = $fcp->get_size ($uri)
97 Finds and returns the size (rounded up to the nearest power of two)
98 of the given document.
99
100 UNTESTED.

102 MISSING: ClientGet, ClientPut
103
104 THE Net::FCP::Txn CLASS
105 All requests (or transactions) are executed in a asynchroneous way (LIE:
106 uploads are blocking). For each request, a "Net::FCP::Txn" object is
107 created (worse: a tcp connection is created, too).
108
109 For each request there is actually a different subclass (and it's
110 possible to subclass these, although of course not documented).
111
112 The most interesting method is "result".
113
114 new arg => val,...
115 Creates a new "Net::FCP::Txn" object. Not normally used.
116
117 $result = $txn->result
118 Waits until a result is available and then returns it.
119
120 This waiting is (depending on your event modul) not very efficient,
121 as it is done outside the "mainloop".
