O God, Trinity of love, from the profound communion of your divine life, pour out upon us a torrent of fraternal love. Grant us the love reflected in the actions of Jesus, in his family of Nazareth, and in the early Christian community.
Former tour pro Bobby Clampett, a longtime student of golf swings who has his own instructional school, Impact Zone Golf, says the lasting moral of Square-to-Square is that no one swing fits everybody. "When you study the swing close up, you see every possible variation of backswing among great players," says Clampett, who added that his pursuit of honing various methods undid his playing career. "Looking for answers in the style of swing rather than what the player is creating at impact is an epidemic that's killing the game."
This document applies to the first version (i.e. version 1.0) of the BitTorrent protocol specification. Currently, this applies to the torrent file structure, peer wire protocol, and the Tracker HTTP/HTTPS protocol specifications. As newer revisions of each protocol are defined, they should be specified on their own separate pages, not here.
The tracker is an HTTP/HTTPS service which responds to HTTP GET requests. The requests include metrics from clients that help the tracker keep overall statistics about the torrent. The response includes a peer list that helps the client participate in the torrent. The base URL consists of the "announce URL" as defined in the metainfo (.torrent) file. The parameters are then added to this URL, using standard CGI methods (i.e. a '?' after the announce URL, followed by 'param=value' sequences separated by '&').
As mentioned above, the list of peers is length 50 by default. If there are fewer peers in the torrent, then the list will be smaller. Otherwise, the tracker randomly selects peers to include in the response. The tracker may choose to implement a more intelligent mechanism for peer selection when responding to a request. For instance, reporting seeds to other seeders could be avoided.
By convention most trackers support another form of request, which queries the state of a given torrent (or all torrents) that the tracker is managing. This is referred to as the "scrape page" because it automates the otherwise tedious process of "screen scraping" the tracker's stats page.
The scrape URL may be supplemented by the optional parameter info_hash, a 20-byte value as described above. This restricts the tracker's report to that particular torrent. Otherwise stats for all torrents that the tracker is managing are returned. Software authors are strongly encouraged to use the info_hash parameter when at all possible, to reduce the load and bandwidth of the tracker.
The initiator of a connection is expected to transmit their handshake immediately. The recipient may wait for the initiator's handshake, if it is capable of serving multiple torrents simultaneously (torrents are uniquely identified by their infohash). However, the recipient must respond as soon as it sees the info_hash part of the handshake (the peer id will presumably be sent after the recipient sends its own handshake). The tracker's NAT-checking feature does not send the peer_id field of the handshake.
Some clients (Deluge for example) send bitfield with missing pieces even if it has all data. Then it sends rest of pieces as have messages. They are saying this helps against ISP filtering of BitTorrent protocol. It is called lazy bitfield.
The super-seed feature in S-5.5 and on is a new seeding algorithm designed to help a torrent initiator with limited bandwidth "pump up" a large torrent, reducing the amount of data it needs to upload in order to spawn new seeds in the torrent.
This method has resulted in much higher seeding efficiencies, by both inducing peers into taking only the rarest data, reducing the amount of redundant data sent, and limiting the amount of data sent to peers which do not contribute to the swarm. Prior to this, a seed might have to upload 150% to 200% of the total size of a torrent before other clients became seeds. However, a large torrent seeded with a single client running in super-seed mode was able to do so after only uploading 105% of the data. This is 150-200% more efficient than when using a standard seed.
This extension is to allow for the tracking of peers downloading torrents without the use of a standard tracker. A peer implementing this protocol becomes a "tracker" and stores lists of other nodes/peers which can be used to locate new peers.
There are at least two specification for how to combine a torrent download with a HTTP download. The first standard, implemented by BitTornado is quite easy to implement in the client, but is intrusive on the HTTP in that it requires a script handling requests on the server side. i.e. A plain HTTP server that just serves plain files isn't enough. The benfits is that the script can be more abuse resistant. This specification is found here: -spec.txt or as BEP-17.
The second specification requires slightly more from the client, but downloads from plain HTTP servers. It is specified here: or as BEP-19. It has been implemented by GetRight, libtorrent, Mainline, BitComet, Vuze.
This is a protocol for exchanging extension information and was derived from an early version of azureus' extension protocol. It adds one message for exchanging arbitrary handshake information including defined extension messages, mapping extensions to specific message IDs. It is documented here: _protocol.html and is implemented at least by libtorrent, uTorrent, Mainline, Transmission, Azureus and BitComet.
Before the recent 1-2 updates, pdfs,pictures and .torrent meta files used to get saved in temp folder which I LOVED very much. Recently these are getting save in my download folder instead of saving in the temp folder. 2b1af7f3a8
