Set_file_hash() and file_hash() functions are obsolete, as v2 torrents have The rules for padding and alignment is well defined for Pad_file_limit and alignment parameters to the create_torrent constructor Mutable_torrent_support flag is also always on.

Is no longer relevant (as it's effectively always on). Is the SHA-256 merkle root hash of the 16 kiB blocks in that piece.Īll v2 torrents have pieces aligned to files, so the optimize_alignment flag In v2 torrents, each file forms a merkle tree and each v2 piece hash One important difference is that v2 hashes are SHA-256 hashes, and they are set Set_hash2(), which is similar to set_hash(), but for the v2-part of a torrent. Perhaps the most important addition for v2 torrents is the new member function To create v1-only torrents use the v1_only flag. torrentsĬompatible with both v1 and v2 bittorrent clients. The create_torrent class creates hybrid torrents by default. trackers () for ( lt :: announce_entry const & ae : h. There are two members, V1 and V2.Įxample: std :: vector tr = h. Type announce_infohash, for each bittorrent version. TheĪnnounce_endpoint in turn has an array info_hashes, containing objects of Each listen socket is announced independently. Each corresponding toĪ local listen socket.

Since hybrid torrentsĪnnounce once per info-hash (once for v1 and once for v2), the tracker resultsĪre also reported per bittorrent version.Įach tracker ( announce_entry) has a list of endpoints. On major change in the API is reporting of trackers. Torrent_handle::info_hashes(), in order to get both v1 and v2 hashes. Set, it will compare false to a sha1_hash of just the v1 hash.Ĭalls to torrent_handle::info_hash() may need to be replaced by Now deprecated in favor of an info_hashes member, which is of typeĪn info_hash_t object for a hybrid torrent will have both the v1 and v2 hashes Torrent_delete_failed_alert all have info_hash members. The alerts torrent_removed_alert, torrent_deleted_alert, Perhaps most noteworthy is that add_torrent_params::info_hash is nowĭeprecated in favor of add_torrent_params::info_hashes which is an The implicit conversion is deprecated though. For backwards compatibility, info_hash_t is implicitlyĬonvertible to and from sha1_hash and is interpreted as the v1 info-hash. Many places that previously took an info-hash as sha1_hash now With bittorrent v2 support, each torrent may now have two separate info hashes,
