      Declared in "libtorrent/piece_block.hpp"

      │ │ │ │ +

      libtorrent has a plugin interface for implementing extensions to the protocol. │ │ │ │ +These can be general extensions for transferring metadata or peer exchange │ │ │ │ +extensions, or it could be used to provide a way to customize the protocol │ │ │ │ +to fit a particular (closed) network.

      │ │ │ │ +

      In short, the plugin interface makes it possible to:

      │ │ │ │ +
        │ │ │ │ +
      • register extension messages (sent in the extension handshake), see │ │ │ │ +extensions.
        • │ │ │ │ +
      • add data and parse data from the extension handshake.
        • │ │ │ │ +
      • send extension messages and standard bittorrent messages.
        • │ │ │ │ +
      • override or block the handling of standard bittorrent messages.
        • │ │ │ │ +
      • save and restore state via the session state
        • │ │ │ │ +
      • see all alerts that are posted
        • │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +

      a word of caution

      │ │ │ │ +

      Writing your own plugin is a very easy way to introduce serious bugs such as │ │ │ │ +dead locks and race conditions. Since a plugin has access to internal │ │ │ │ +structures it is also quite easy to sabotage libtorrent's operation.

      │ │ │ │ +

      All the callbacks are always called from the libtorrent network thread. In │ │ │ │ +case portions of your plugin are called from other threads, typically the main │ │ │ │ +thread, you cannot use any of the member functions on the internal structures │ │ │ │ +in libtorrent, since those require being called from the libtorrent network │ │ │ │ +thread . Furthermore, you also need to synchronize your own shared data │ │ │ │ +within the plugin, to make sure it is not accessed at the same time from the │ │ │ │ +libtorrent thread (through a callback). If you need to send out a message │ │ │ │ +from another thread, it is advised to use an internal queue, and do the │ │ │ │ +actual sending in tick().

      │ │ │ │ +

      Since the plugin interface gives you easy access to internal structures, it │ │ │ │ +is not supported as a stable API. Plugins should be considered specific to a │ │ │ │ +specific version of libtorrent. Although, in practice the internals mostly │ │ │ │ +don't change that dramatically.

      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +

      plugin-interface

      │ │ │ │ +

      The plugin interface consists of three base classes that the plugin may │ │ │ │ +implement. These are called plugin, torrent_plugin and peer_plugin. │ │ │ │ +They are found in the <libtorrent/extensions.hpp> header.

      │ │ │ │ +

      These plugins are instantiated for each session, torrent and possibly each peer, │ │ │ │ +respectively.

      │ │ │ │ +

      For plugins that only need per torrent state, it is enough to only implement │ │ │ │ +torrent_plugin and pass a constructor function or function object to │ │ │ │ +session::add_extension() or torrent_handle::add_extension() (if the │ │ │ │ +torrent has already been started and you want to hook in the extension at │ │ │ │ +run-time).

      │ │ │ │ +

      The signature of the function is:

      │ │ │ │ +
      │ │ │ │ +std::shared_ptr<torrent_plugin> (*)(torrent_handle const&, client_data_t);
│ │ │ │ +
      │ │ │ │ +

      The second argument is the userdata passed to session::add_torrent() or │ │ │ │ +torrent_handle::add_extension().

      │ │ │ │ +

      The function should return a std::shared_ptr<torrent_plugin> which │ │ │ │ +may or may not be 0. If it is a nullptr, the extension is simply ignored │ │ │ │ +for this torrent. If it is a valid pointer (to a class inheriting │ │ │ │ +torrent_plugin), it will be associated with this torrent and callbacks │ │ │ │ +will be made on torrent events.

      │ │ │ │ +

      For more elaborate plugins which require session wide state, you would │ │ │ │ +implement plugin, construct an object (in a std::shared_ptr) and pass │ │ │ │ +it in to session::add_extension().

      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +

      custom alerts

      │ │ │ │ +

      Since plugins are running within internal libtorrent threads, one convenient │ │ │ │ +way to communicate with the client is to post custom alerts.

      │ │ │ │ +

      The expected interface of any alert, apart from deriving from the alert │ │ │ │ +base class, looks like this:

      │ │ │ │ 
      │ │ │ │ -struct piece_block
│ │ │ │ -{
│ │ │ │ -   piece_block (piece_index_t p_index, int b_index);
│ │ │ │ -   piece_block () = default;
│ │ │ │ -   bool operator< (piece_block const& b) const;
│ │ │ │ -   bool operator== (piece_block const& b) const;
│ │ │ │ -   bool operator!= (piece_block const& b) const;
│ │ │ │ +static const int alert_type = <unique alert ID>;
│ │ │ │ +virtual int type() const { return alert_type; }
│ │ │ │  
│ │ │ │ -   static const piece_block invalid;
│ │ │ │ -   piece_index_t piece_index {0};
│ │ │ │ -   int block_index  = 0;
│ │ │ │ +virtual std::string message() const;
│ │ │ │ +
│ │ │ │ +static const alert_category_t static_category = <bitmask of alert::category_t flags>;
│ │ │ │ +virtual alert_category_t category() const { return static_category; }
│ │ │ │ +
│ │ │ │ +virtual char const* what() const { return <string literal of the name of this alert>; }
│ │ │ │ +
      │ │ │ │ +

      The alert_type is used for the type-checking in alert_cast. It must │ │ │ │ +not collide with any other alert. The built-in alerts in libtorrent will │ │ │ │ +not use alert type IDs greater than user_alert_id. When defining your │ │ │ │ +own alert, make sure it's greater than this constant.

      │ │ │ │ +

      type() is the run-time equivalence of the alert_type.

      │ │ │ │ +

      The message() virtual function is expected to construct a useful │ │ │ │ +string representation of the alert and the event or data it represents. │ │ │ │ +Something convenient to put in a log file for instance.

      │ │ │ │ +

      clone() is used internally to copy alerts. The suggested implementation │ │ │ │ +of simply allocating a new instance as a copy of *this is all that's │ │ │ │ +expected.

      │ │ │ │ +

      The static category is required for checking whether or not the category │ │ │ │ +for a specific alert is enabled or not, without instantiating the alert. │ │ │ │ +The category virtual function is the run-time equivalence.

      │ │ │ │ +

      The what() virtual function may simply be a string literal of the class │ │ │ │ +name of your alert.

      │ │ │ │ +

      For more information, see the alert section.

      torrent_peer_equal()

      │ │ │ │ -

      Declared in "libtorrent/torrent_peer.hpp"

      │ │ │ │ +

      This function is called each time a new peer is connected to the torrent. You │ │ │ │ +may choose to ignore this by just returning a default constructed │ │ │ │ +shared_ptr (in which case you don't need to override this member │ │ │ │ +function).

      │ │ │ │ +

      If you need an extension to the peer connection (which most plugins do) you │ │ │ │ +are supposed to return an instance of your peer_plugin class. Which in │ │ │ │ +turn will have its hook functions called on event specific to that peer.

      │ │ │ │ +

      The peer_connection_handle will be valid as long as the shared_ptr │ │ │ │ +is being held by the torrent object. So, it is generally a good idea to not │ │ │ │ +keep a shared_ptr to your own peer_plugin. If you want to keep references │ │ │ │ +to it, use weak_ptr.

      If this function throws an exception, the connection will be closed.

      │ │ │ │ -

      Several fields from the add_torrent_params objects are recorded in the │ │ │ │ -magnet link. In order to not include them, they have to be cleared before │ │ │ │ -calling make_magnet_uri(). These fields are used:

      │ │ │ │ -
      │ │ │ │ -ti, info_hashes, url_seeds, dht_nodes, │ │ │ │ -file_priorities, trackers, name, peers.
      │ │ │ │ -

      Depending on what the use case for the resulting magnet link is, clearing │ │ │ │ -peers and dht_nodes is probably a good idea if the add_torrent_params │ │ │ │ -came from a running torrent. Those lists may be long and be ephemeral.

      │ │ │ │ -

      If none of the info_hashes or ti fields are set, there is not │ │ │ │ -info-hash available, and a magnet link cannot be created. In this case │ │ │ │ -make_magnet_uri() returns an empty string.

      │ │ │ │ -

      The recommended way to generate a magnet link from a torrent_handle is to │ │ │ │ -call save_resume_data(), which will post a save_resume_data_alert │ │ │ │ -containing an add_torrent_params object. This can then be passed to │ │ │ │ -make_magnet_uri().

      │ │ │ │ -

      The overload that takes a torrent_handle will make blocking calls to │ │ │ │ -query information about the torrent. If the torrent handle is invalid, │ │ │ │ -an empty string is returned.

      These hooks are called when the torrent is paused and resumed respectively. │ │ │ │ +The return value indicates if the event was handled. A return value of │ │ │ │ +true indicates that it was handled, and no other plugin after this one │ │ │ │ +will have this hook function called, and the standard handler will also not be │ │ │ │ +invoked. So, returning true effectively overrides the standard behavior of │ │ │ │ +pause or resume.

      │ │ │ │ +

      Note that if you call pause() or resume() on the torrent from your │ │ │ │ +handler it will recurse back into your handler, so in order to invoke the │ │ │ │ +standard handler, you have to keep your own state on whether you want standard │ │ │ │ +behavior or overridden behavior.

      seed_mode
      │ │ │ │ -

      If seed_mode is set, libtorrent will assume that all files │ │ │ │ -are present for this torrent and that they all match the hashes in │ │ │ │ -the torrent file. Each time a peer requests to download a block, │ │ │ │ -the piece is verified against the hash, unless it has been verified │ │ │ │ -already. If a hash fails, the torrent will automatically leave the │ │ │ │ -seed mode and recheck all the files. The use case for this mode is │ │ │ │ -if a torrent is created and seeded, or if the user already know │ │ │ │ -that the files are complete, this is a way to avoid the initial │ │ │ │ -file checks, and significantly reduce the startup time.

      │ │ │ │ -

      Setting seed_mode on a torrent without metadata (a │ │ │ │ -.torrent file) is a no-op and will be ignored.

      │ │ │ │ -

      It is not possible to set the seed_mode flag on a torrent after it has │ │ │ │ -been added to a session. It is possible to clear it though.

      │ │ │ │ -
      │ │ │ │ -
      upload_mode
      │ │ │ │ -

      If upload_mode is set, the torrent will be initialized in │ │ │ │ -upload-mode, which means it will not make any piece requests. This │ │ │ │ -state is typically entered on disk I/O errors, and if the torrent │ │ │ │ -is also auto managed, it will be taken out of this state │ │ │ │ -periodically (see settings_pack::optimistic_disk_retry).

      │ │ │ │ -

      This mode can be used to avoid race conditions when │ │ │ │ -adjusting priorities of pieces before allowing the torrent to start │ │ │ │ -downloading.

      │ │ │ │ -

      If the torrent is auto-managed (auto_managed), the torrent │ │ │ │ -will eventually be taken out of upload-mode, regardless of how it │ │ │ │ -got there. If it's important to manually control when the torrent │ │ │ │ -leaves upload mode, don't make it auto managed.

      │ │ │ │ -
      share_mode
      │ │ │ │ -

      determines if the torrent should be added in share mode or not. │ │ │ │ -Share mode indicates that we are not interested in downloading the │ │ │ │ -torrent, but merely want to improve our share ratio (i.e. increase │ │ │ │ -it). A torrent started in share mode will do its best to never │ │ │ │ -download more than it uploads to the swarm. If the swarm does not │ │ │ │ -have enough demand for upload capacity, the torrent will not │ │ │ │ -download anything. This mode is intended to be safe to add any │ │ │ │ -number of torrents to, without manual screening, without the risk │ │ │ │ -of downloading more than is uploaded.

      │ │ │ │ -

      A torrent in share mode sets the priority to all pieces to 0, │ │ │ │ -except for the pieces that are downloaded, when pieces are decided │ │ │ │ -to be downloaded. This affects the progress bar, which might be set │ │ │ │ -to "100% finished" most of the time. Do not change file or piece │ │ │ │ -priorities for torrents in share mode, it will make it not work.

      │ │ │ │ -

      The share mode has one setting, the share ratio target, see │ │ │ │ -settings_pack::share_mode_target for more info.

      │ │ │ │ -

      If auto_managed is set, the torrent will be queued, │ │ │ │ -started and seeded automatically by libtorrent. When this is set, │ │ │ │ -the torrent should also be started as paused. The default queue │ │ │ │ -order is the order the torrents were added. They are all downloaded │ │ │ │ -in that order. For more details, see queuing.

      super_seeding
      │ │ │ │ -
      sets the torrent into super seeding/initial seeding mode. If the torrent │ │ │ │ -is not a seed, this flag has no effect.
      │ │ │ │ -
      │ │ │ │ -
      │ │ │ │ -
      sequential_download
      │ │ │ │ -
      sets the sequential download state for the torrent. In this mode the │ │ │ │ -piece picker will pick pieces with low index numbers before pieces with │ │ │ │ -high indices. The actual pieces that are picked depend on other factors │ │ │ │ -still, such as which pieces a peer has and whether it is in parole mode │ │ │ │ -or "prefer whole pieces"-mode. Sequential mode is not ideal for streaming │ │ │ │ -media. For that, see set_piece_deadline() instead.
      │ │ │ │ -
      │ │ │ │ -
      │ │ │ │ -
      stop_when_ready
      │ │ │ │ -

      When this flag is set, the torrent will force stop whenever it │ │ │ │ -transitions from a non-data-transferring state into a data-transferring │ │ │ │ -state (referred to as being ready to download or seed). This is useful │ │ │ │ -for torrents that should not start downloading or seeding yet, but want │ │ │ │ -to be made ready to do so. A torrent may need to have its files checked │ │ │ │ -for instance, so it needs to be started and possibly queued for checking │ │ │ │ -(auto-managed and started) but as soon as it's done, it should be │ │ │ │ -stopped.

      │ │ │ │ -

      Force stopped means auto-managed is set to false and it's paused. As │ │ │ │ -if the auto_manages flag is cleared and the paused flag is set on the torrent.

      │ │ │ │ -

      Note that the torrent may transition into a downloading state while │ │ │ │ -setting this flag, and since the logic is edge triggered you may │ │ │ │ -miss the edge. To avoid this race, if the torrent already is in a │ │ │ │ -downloading state when this call is made, it will trigger the │ │ │ │ -stop-when-ready immediately.

      │ │ │ │ -

      When the stop-when-ready logic fires, the flag is cleared. Any │ │ │ │ -subsequent transitions between downloading and non-downloading states │ │ │ │ -will not be affected, until this flag is set again.

      │ │ │ │ -

      The behavior is more robust when setting this flag as part of adding │ │ │ │ -the torrent. See add_torrent_params.

      │ │ │ │ -

      The stop-when-ready flag fixes the inherent race condition of waiting │ │ │ │ -for the state_changed_alert and then call pause(). The download/seeding │ │ │ │ -will most likely start in between posting the alert and receiving the │ │ │ │ -call to pause.

      │ │ │ │ -

      A downloading state is one where peers are being connected. Which means │ │ │ │ -just downloading the metadata via the ut_metadata extension counts │ │ │ │ -as a downloading state. In order to stop a torrent once the metadata │ │ │ │ -has been downloaded, instead set all file priorities to dont_download

      │ │ │ │ -
      │ │ │ │ -
      override_trackers
      │ │ │ │ -
      when this flag is set, the tracker list in the add_torrent_params │ │ │ │ -object override any trackers from the torrent file. If the flag is │ │ │ │ -not set, the trackers from the add_torrent_params object will be │ │ │ │ -added to the list of trackers used by the torrent. │ │ │ │ -This flag is set by read_resume_data() if there are trackers present in │ │ │ │ -the resume data file. This effectively makes the trackers saved in the │ │ │ │ -resume data take precedence over the original trackers. This includes if │ │ │ │ -there's an empty list of trackers, to support the case where they were │ │ │ │ -explicitly removed in the previous session. │ │ │ │ -This flag is not saved by write_resume_data()
      │ │ │ │ -
      │ │ │ │ -
      │ │ │ │ -
      override_web_seeds
      │ │ │ │ -
      If this flag is set, the web seeds from the add_torrent_params │ │ │ │ -object will override any web seeds in the torrent file. If it's not │ │ │ │ -set, web seeds in the add_torrent_params object will be added to the │ │ │ │ -list of web seeds used by the torrent. │ │ │ │ -This flag is set by read_resume_data() if there are web seeds present in │ │ │ │ -the resume data file. This effectively makes the web seeds saved in the │ │ │ │ -resume data take precedence over the original ones. This includes if │ │ │ │ -there's an empty list of web seeds, to support the case where they were │ │ │ │ -explicitly removed in the previous session. │ │ │ │ -This flag is not saved by write_resume_data()
      │ │ │ │ -
      │ │ │ │ -
      │ │ │ │ -
      need_save_resume
      │ │ │ │ -

      if this flag is set (which it is by default) the torrent will be │ │ │ │ -considered needing to save its resume data immediately, in the │ │ │ │ -category if_metadata_changed. See resume_data_flags_t and │ │ │ │ -save_resume_data() for details.

      │ │ │ │ -

      This flag is cleared by a successful call to save_resume_data() │ │ │ │ -This flag is not saved by write_resume_data(), since it represents an │ │ │ │ -ephemeral state of a running torrent.

      disable_dht
      │ │ │ │ -
      set this flag to disable DHT for this torrent. This lets you have the DHT │ │ │ │ -enabled for the whole client, and still have specific torrents not │ │ │ │ -participating in it. i.e. not announcing to the DHT nor picking up peers │ │ │ │ -from it.

      │ │ │ │ -
      │ │ │ │ -
      │ │ │ │ -
      no_verify_files
      │ │ │ │ -
      if this flag is set, the resume data will be assumed to be correct │ │ │ │ -without validating it against any files on disk. This may be used when │ │ │ │ -restoring a session by loading resume data from disk. It will save time │ │ │ │ -and also delay any hard disk errors until files are actually needed. If │ │ │ │ -the resume data cannot be trusted, or if a torrent is added for the first │ │ │ │ -time to some save path that may already have some of the files, this flag │ │ │ │ -should not be set.
      │ │ │ │ -
      │ │ │ │ -
      │ │ │ │ -
      default_dont_download
      │ │ │ │ -
      default all file priorities to dont_download. This is useful for adding │ │ │ │ -magnet links where the number of files is unknown, but the │ │ │ │ -file_priorities is still set for some files. Any file not covered by │ │ │ │ -the file_priorities list will be set to normal download priority, │ │ │ │ -unless this flag is set, in which case they will be set to 0 │ │ │ │ -(dont_download).
      │ │ │ │ -
      │ │ │ │ -
      │ │ │ │ -
      i2p_torrent
      │ │ │ │ -
      this flag makes the torrent be considered an "i2p torrent" for purposes │ │ │ │ -of the allow_i2p_mixed setting. When mixing regular peers and i2p peers │ │ │ │ -is disabled, i2p torrents won't add normal peers to its peer list. │ │ │ │ -Note that non i2p torrents may still allow i2p peers (on the off-chance │ │ │ │ -that a tracker return them and the session is configured with a SAM │ │ │ │ -connection). │ │ │ │ -This flag is set automatically when adding a torrent that has at least │ │ │ │ -one tracker whose hostname ends with .i2p. │ │ │ │ -It's also set by parse_magnet_uri() if the tracker list contains such │ │ │ │ -URL.

      torrent_handle

      │ │ │ │ -

      Declared in "libtorrent/torrent_handle.hpp"

      │ │ │ │ -

      You will usually have to store your torrent handles somewhere, since it's │ │ │ │ -the object through which you retrieve information about the torrent and │ │ │ │ -aborts the torrent.

      │ │ │ │ -
      │ │ │ │ -

      Warning

      │ │ │ │ -

      Any member function that returns a value or fills in a value has to be │ │ │ │ -made synchronously. This means it has to wait for the main thread to │ │ │ │ -complete the query before it can return. This might potentially be │ │ │ │ -expensive if done from within a GUI thread that needs to stay │ │ │ │ -responsive. Try to avoid querying for information you don't need, and │ │ │ │ -try to do it in as few calls as possible. You can get most of the │ │ │ │ -interesting information about a torrent from the │ │ │ │ -torrent_handle::status() call.

      │ │ │ │ -
      │ │ │ │ -

      The default constructor will initialize the handle to an invalid state. │ │ │ │ -Which means you cannot perform any operation on it, unless you first │ │ │ │ -assign it a valid handle. If you try to perform any operation on an │ │ │ │ -uninitialized handle, it will throw invalid_handle.

      │ │ │ │ -
      │ │ │ │ -

      Warning

      │ │ │ │ -

      All operations on a torrent_handle may throw system_error │ │ │ │ -exception, in case the handle is no longer referring to a torrent. │ │ │ │ -There is one exception is_valid() will never throw. Since the torrents │ │ │ │ -are processed by a background thread, there is no guarantee that a │ │ │ │ -handle will remain valid between two calls.

      If the piece is already downloaded when this call is made, nothing │ │ │ │ -happens, unless the alert_when_available flag is set, in which case it │ │ │ │ -will have the same effect as calling read_piece() for index.

      │ │ │ │ -

      deadline is the number of milliseconds until this piece should be │ │ │ │ -completed.

      The flags parameter can be used to specify the granularity of the │ │ │ │ -file progress.

      add_torrent_params

      │ │ │ │ +

      Declared in "libtorrent/add_torrent_params.hpp"

      │ │ │ │ +

      The add_torrent_params contains all the information in a .torrent file │ │ │ │ +along with all information necessary to add that torrent to a session. │ │ │ │ +The key fields when adding a torrent are:

      │ │ │ │ +
        │ │ │ │ +
      • ti - the immutable info-dict part of the torrent
        • │ │ │ │ +
      • info_hash - when you don't have the metadata (.torrent file). This │ │ │ │ +uniquely identifies the torrent and can validate the info-dict when │ │ │ │ +received from the swarm.
        • │ │ │ │ +
      │ │ │ │ +

      In order to add a torrent to a session, one of those fields must be set │ │ │ │ +in addition to save_path. The add_torrent_params object can then be │ │ │ │ +passed into one of the session::add_torrent() overloads or │ │ │ │ +session::async_add_torrent().

      │ │ │ │ +

      If you only specify the info-hash, the torrent file will be downloaded │ │ │ │ +from peers, which requires them to support the metadata extension. For │ │ │ │ +the metadata extension to work, libtorrent must be built with extensions │ │ │ │ +enabled (TORRENT_DISABLE_EXTENSIONS must not be defined). It also │ │ │ │ +takes an optional name argument. This may be left empty in case no │ │ │ │ +name should be assigned to the torrent. In case it's not, the name is │ │ │ │ +used for the torrent as long as it doesn't have metadata. See │ │ │ │ +torrent_handle::name.

      │ │ │ │ +

      The add_torrent_params is also used when requesting resume data for a │ │ │ │ +torrent. It can be saved to and restored from a file and added back to a │ │ │ │ +new session. For serialization and de-serialization of │ │ │ │ +add_torrent_params objects, see read_resume_data() and │ │ │ │ +write_resume_data().

      │ │ │ │ +

      The add_torrent_params is also used to represent a parsed .torrent │ │ │ │ +file. It can be loaded via load_torrent_file(), load_torrent_buffer() and │ │ │ │ +load_torrent_parsed(). It can be saved via write_torrent_file().

      save_resume_data() asks libtorrent to generate fast-resume data for │ │ │ │ -this torrent. The fast resume data (stored in an add_torrent_params │ │ │ │ -object) can be used to resume a torrent in the next session without │ │ │ │ -having to check all files for which pieces have been downloaded. It │ │ │ │ -can also be used to save a .torrent file for a torrent_handle.

      │ │ │ │ -

      This operation is asynchronous, save_resume_data will return │ │ │ │ -immediately. The resume data is delivered when it's done through a │ │ │ │ -save_resume_data_alert.

      │ │ │ │ -

      The operation will fail, and post a save_resume_data_failed_alert │ │ │ │ -instead, in the following cases:

      │ │ │ │ -
      │ │ │ │ -
        │ │ │ │ -
      1. The torrent is in the process of being removed.
        2. │ │ │ │ -
      2. No torrent state has changed since the last saving of resume │ │ │ │ -data, and the only_if_modified flag is set. │ │ │ │ -metadata (see libtorrent's metadata from peers extension)

      │ │ │ │ -

      Note that some counters may be outdated by the time you receive the fast resume data

      │ │ │ │ -

      When saving resume data because of shutting down, make sure not to │ │ │ │ -remove_torrent() before you receive the save_resume_data_alert. │ │ │ │ -There's no need to pause the session or torrent when saving resume │ │ │ │ -data.

      │ │ │ │ -

      The paused state of a torrent is saved in the resume data, so pausing │ │ │ │ -all torrents before saving resume data will all torrents be restored │ │ │ │ -in a paused state.

      │ │ │ │ -
      │ │ │ │ -

      Note

      │ │ │ │ -

      It is typically a good idea to save resume data whenever a torrent │ │ │ │ -is completed or paused. If you save resume data for torrents when they are │ │ │ │ -paused, you can accelerate the shutdown process by not saving resume │ │ │ │ -data again for those torrents. Completed torrents should have their │ │ │ │ -resume data saved when they complete and on exit, since their │ │ │ │ -statistics might be updated.

      │ │ │ │ -
      │ │ │ │ -

      Example code to pause and save resume data for all torrents and wait │ │ │ │ -for the alerts:

      │ │ │ │ +

      we don't allow type-unsafe operations

      │ │ │ │ +

      The disk I/O can be customized in libtorrent. In previous versions, the │ │ │ │ +customization was at the level of each torrent. Now, the customization point │ │ │ │ +is at the session level. All torrents added to a session will use the same │ │ │ │ +disk I/O subsystem, as determined by the disk_io_constructor (in │ │ │ │ +session_params).

      │ │ │ │ +

      This allows the disk subsystem to also customize threading and disk job │ │ │ │ +management.

      │ │ │ │ +

      To customize the disk subsystem, implement disk_interface and provide a │ │ │ │ +factory function to the session constructor (via session_params).

      │ │ │ │ -

      When a torrent is removed or turns into a seed, all torrents with │ │ │ │ -greater queue positions have their positions decreased to fill in the │ │ │ │ -space in the sequence.

      queue_position() returns the torrent's position in the download │ │ │ │ -queue. The torrents with the smallest numbers are the ones that are │ │ │ │ -being downloaded. The smaller number, the closer the torrent is to the │ │ │ │ -front of the line to be started.

      The set_ssl_certificate_buffer() overload takes the actual certificate, │ │ │ │ -private key and DH params as strings, rather than paths to files.

      │ │ │ │ -

      cert is a path to the (signed) certificate in .pem format │ │ │ │ -corresponding to this torrent.

      │ │ │ │ -

      private_key is a path to the private key for the specified │ │ │ │ -certificate. This must be in .pem format.

      │ │ │ │ -

      dh_params is a path to the Diffie-Hellman parameter file, which │ │ │ │ -needs to be in .pem format. You can generate this file using the │ │ │ │ -openssl command like this: openssl dhparam -outform PEM -out │ │ │ │ -dhparams.pem 512.

      │ │ │ │ -

      passphrase may be specified if the private key is encrypted and │ │ │ │ -requires a passphrase to be decrypted.

      Note that when a torrent first starts up, and it needs a certificate, │ │ │ │ -it will suspend connecting to any peers until it has one. It's │ │ │ │ -typically desirable to resume the torrent after setting the SSL │ │ │ │ -certificate.

      torrent_file() returns a pointer to the torrent_info object │ │ │ │ -associated with this torrent. The torrent_info object may be a copy │ │ │ │ -of the internal object. If the torrent doesn't have metadata, the │ │ │ │ -pointer will not be initialized (i.e. a nullptr). The torrent may be │ │ │ │ -in a state without metadata only if it was started without a .torrent │ │ │ │ -file, e.g. by being added by magnet link.

      │ │ │ │ -

      Note that the torrent_info object returned here may be a different │ │ │ │ -instance than the one added to the session, with different attributes │ │ │ │ -like piece layers, dht nodes and trackers. A torrent_info object does │ │ │ │ -not round-trip cleanly when added to a session.

      │ │ │ │ -

      If you want to save a .torrent file from the torrent_handle, instead │ │ │ │ -call save_resume_data() and write_torrent_file() the │ │ │ │ -add_torrent_params object passed back in the alert.

      │ │ │ │ -

      torrent_file_with_hashes() returns a copy of the internal │ │ │ │ -torrent_info and piece layer hashes (if it's a v2 torrent). The piece │ │ │ │ -layers will only be included if they are available. If this torrent │ │ │ │ -was added from a .torrent file with piece layers or if it's seeding, │ │ │ │ -the piece layers are available. This function is more expensive than │ │ │ │ -torrent_file() since it needs to make copies of this information.

      │ │ │ │ -

      The torrent_file_with_hashes() is here for backwards compatibility │ │ │ │ -when constructing a create_torrent object from a torrent_info that's │ │ │ │ -in a session. Prefer save_resume_data() + write_torrent_file().

      │ │ │ │ -

      Note that a torrent added from a magnet link may not have the full │ │ │ │ -merkle trees for all files, and hence not have the complete piece │ │ │ │ -layers. In that state, you cannot create a .torrent file even from │ │ │ │ -the torrent_info returned from torrent_file_with_hashes(). Once the │ │ │ │ -torrent completes downloading all files, becoming a seed, you can │ │ │ │ -make a .torrent file from it.

      These functions are used to set and get the priority of individual │ │ │ │ -pieces. By default all pieces have priority 4. That means that the │ │ │ │ -random rarest first algorithm is effectively active for all pieces. │ │ │ │ -You may however change the priority of individual pieces. There are 8 │ │ │ │ -priority levels. 0 means not to download the piece at all. Otherwise, │ │ │ │ -lower priority values means less likely to be picked. Piece priority │ │ │ │ -takes precedence over piece availability. Every piece with priority 7 │ │ │ │ -will be attempted to be picked before a priority 6 piece and so on.

      │ │ │ │ -

      The default priority of pieces is 4.

      │ │ │ │ -

      Piece priorities can not be changed for torrents that have not │ │ │ │ -downloaded the metadata yet. Magnet links won't have metadata │ │ │ │ -immediately. see the metadata_received_alert.

      piece_priority sets or gets the priority for an individual piece, │ │ │ │ -specified by index.

      │ │ │ │ -

      prioritize_pieces takes a vector of integers, one integer per │ │ │ │ -piece in the torrent. All the piece priorities will be updated with │ │ │ │ -the priorities in the vector. │ │ │ │ -The second overload of prioritize_pieces that takes a vector of pairs │ │ │ │ -will update the priorities of only select pieces, and leave all other │ │ │ │ -unaffected. Each pair is (piece, priority). That is, the first item is │ │ │ │ -the piece index and the second item is the priority of that piece. │ │ │ │ -Invalid entries, where the piece index or priority is out of range, are │ │ │ │ -not allowed.

      │ │ │ │ -

      get_piece_priorities returns a vector with one element for each piece │ │ │ │ -in the torrent. Each element is the current priority of that piece.

      It's possible to cancel the effect of file priorities by setting the │ │ │ │ -priorities for the affected pieces. Care has to be taken when mixing │ │ │ │ -usage of file- and piece priorities.

      prioritize_files() takes a vector that has at as many elements as │ │ │ │ -there are files in the torrent. Each entry is the priority of that │ │ │ │ -file. The function sets the priorities of all the pieces in the │ │ │ │ -torrent based on the vector.

      │ │ │ │ -

      get_file_priorities() returns a vector with the priorities of all │ │ │ │ -files.

      │ │ │ │ -

      The priority values are the same as for piece_priority(). See │ │ │ │ -download_priority_t.

      │ │ │ │ -

      Whenever a file priority is changed, all other piece priorities are │ │ │ │ -reset to match the file priorities. In order to maintain special │ │ │ │ -priorities for particular pieces, piece_priority() has to be called │ │ │ │ -again for those pieces.

      │ │ │ │ -

      You cannot set the file priorities on a torrent that does not yet have │ │ │ │ -metadata or a torrent that is a seed. file_priority(int, int) and │ │ │ │ -prioritize_files() are both no-ops for such torrents.

      │ │ │ │ -

      Since changing file priorities may involve disk operations (of moving │ │ │ │ -files in- and out of the part file), the internal accounting of file │ │ │ │ -priorities happen asynchronously. i.e. setting file priorities and then │ │ │ │ -immediately querying them may not yield the same priorities just set. │ │ │ │ -To synchronize with the priorities taking effect, wait for the │ │ │ │ -file_prio_alert.

      │ │ │ │ -

      When combining file- and piece priorities, the resume file will record │ │ │ │ -both. When loading the resume data, the file priorities will be applied │ │ │ │ -first, then the piece priorities.

      │ │ │ │ -

      Moving data from a file into the part file is currently not │ │ │ │ -supported. If a file has its priority set to 0 after it has already │ │ │ │ -been created, it will not be moved into the partfile.

      Moves the file(s) that this torrent are currently seeding from or │ │ │ │ -downloading to. If the given save_path is not located on the same │ │ │ │ -drive as the original save path, the files will be copied to the new │ │ │ │ -drive and removed from their original location. This will block all │ │ │ │ -other disk IO, and other torrents download and upload rates may drop │ │ │ │ -while copying the file.

      │ │ │ │ -

      Since disk IO is performed in a separate thread, this operation is │ │ │ │ -also asynchronous. Once the operation completes, the │ │ │ │ -storage_moved_alert is generated, with the new path as the │ │ │ │ -message. If the move fails for some reason, │ │ │ │ -storage_moved_failed_alert is generated instead, containing the │ │ │ │ -error message.

      │ │ │ │ -

      The flags argument determines the behavior of the copying/moving │ │ │ │ -of the files in the torrent. see move_flags_t.

      │ │ │ │ -

      always_replace_files is the default and replaces any file that │ │ │ │ -exist in both the source directory and the target directory.

      │ │ │ │ -

      fail_if_exist first check to see that none of the copy operations │ │ │ │ -would cause an overwrite. If it would, it will fail. Otherwise it will │ │ │ │ -proceed as if it was in always_replace_files mode. Note that there │ │ │ │ -is an inherent race condition here. If the files in the target │ │ │ │ -directory appear after the check but before the copy or move │ │ │ │ -completes, they will be overwritten. When failing because of files │ │ │ │ -already existing in the target path, the error of │ │ │ │ -move_storage_failed_alert is set to │ │ │ │ -boost::system::errc::file_exists.

      │ │ │ │ -

      The intention is that a client may use this as a probe, and if it │ │ │ │ -fails, ask the user which mode to use. The client may then re-issue │ │ │ │ -the move_storage call with one of the other modes.

      │ │ │ │ -

      dont_replace always keeps the existing file in the target │ │ │ │ -directory, if there is one. The source files will still be removed in │ │ │ │ -that case. Note that it won't automatically re-check files. If an │ │ │ │ -incomplete torrent is moved into a directory with the complete files, │ │ │ │ -pause, move, force-recheck and resume. Without the re-checking, the │ │ │ │ -torrent will keep downloading and files in the new download directory │ │ │ │ -will be overwritten.

      │ │ │ │ -

      Files that have been renamed to have absolute paths are not moved by │ │ │ │ -this function. Keep in mind that files that don't belong to the │ │ │ │ -torrent but are stored in the torrent's directory may be moved as │ │ │ │ -well. This goes for files that have been renamed to absolute paths │ │ │ │ -that still end up inside the save path.

      │ │ │ │ -

      When copying files, sparse regions are not likely to be preserved. │ │ │ │ -This makes it proportionally more expensive to move a large torrent │ │ │ │ -when only few pieces have been downloaded, since the files are then │ │ │ │ -allocated with zeros in the destination directory.

      The constructor that takes an info-hash will initialize the info-hash │ │ │ │ -to the given value, but leave all other fields empty. This is used │ │ │ │ -internally when downloading torrents without the metadata. The │ │ │ │ -metadata will be created by libtorrent as soon as it has been │ │ │ │ -downloaded from the swarm.

      │ │ │ │ -

      The constructor that takes a bdecode_node will create a torrent_info │ │ │ │ -object from the information found in the given torrent_file. The │ │ │ │ -bdecode_node represents a tree node in an bencoded file. To load an │ │ │ │ -ordinary .torrent file into a bdecode_node, use bdecode().

      │ │ │ │ -

      The version that takes a buffer pointer and a size will decode it as a │ │ │ │ -.torrent file and initialize the torrent_info object for you.

      │ │ │ │ -

      The version that takes a filename will simply load the torrent file │ │ │ │ -and decode it inside the constructor, for convenience. This might not │ │ │ │ -be the most suitable for applications that want to be able to report │ │ │ │ -detailed errors on what might go wrong.

      │ │ │ │ -

      There is an upper limit on the size of the torrent file that will be │ │ │ │ -loaded by the overload taking a filename. If it's important that even │ │ │ │ -very large torrent files are loaded, use one of the other overloads.

      │ │ │ │ -

      The overloads that takes an error_code const& never throws if an │ │ │ │ -error occur, they will simply set the error code to describe what went │ │ │ │ -wrong and not fully initialize the torrent_info object. The overloads │ │ │ │ -that do not take the extra error_code parameter will always throw if │ │ │ │ -an error occurs. These overloads are not available when building │ │ │ │ -without exception support.

      │ │ │ │ -

      The overload that takes a span also needs an extra parameter of │ │ │ │ -type from_span_t to disambiguate the std::string overload for │ │ │ │ -string literals. There is an object in the libtorrent namespace of this │ │ │ │ -type called from_span.

      │ │ │ │ -

      The file_storage object contains the information on how to map the │ │ │ │ -pieces to files. It is separated from the torrent_info object because │ │ │ │ -when creating torrents a storage object needs to be created without │ │ │ │ -having a torrent file. When renaming files in a storage, the storage │ │ │ │ -needs to make its own copy of the file_storage in order to make its │ │ │ │ -mapping differ from the one in the torrent file.

      │ │ │ │ -

      orig_files() returns the original (unmodified) file storage for │ │ │ │ -this torrent. This is used by the web server connection, which needs │ │ │ │ -to request files with the original names. Filename may be changed using │ │ │ │ -torrent_info::rename_file().

      Renames the file with the specified index to the new name. The new │ │ │ │ -filename is reflected by the file_storage returned by files() │ │ │ │ -but not by the one returned by orig_files().

      │ │ │ │ -

      If you want to rename the base name of the torrent (for a multi file │ │ │ │ -torrent), you can copy the file_storage (see files() and │ │ │ │ -orig_files() ), change the name, and then use remap_files().

      │ │ │ │ -

      The new_filename can both be a relative path, in which case the │ │ │ │ -file name is relative to the save_path of the torrent. If the │ │ │ │ -new_filename is an absolute path (i.e. is_complete(new_filename) │ │ │ │ -== true), then the file is detached from the save_path of the │ │ │ │ -torrent. In this case the file is not moved when move_storage() is │ │ │ │ -invoked.

      Warning

      │ │ │ │ -

      Using remap_files() is discouraged as it's incompatible with v2 │ │ │ │ -torrents. This is because the piece boundaries and piece hashes in │ │ │ │ -v2 torrents are intimately tied to the file boundaries. Instead, │ │ │ │ -just rename individual files, or implement a custom disk_interface │ │ │ │ -to customize how to store files.

      │ │ │ │ -
      │ │ │ │ -

      Remaps the file storage to a new file layout. This can be used to, for │ │ │ │ -instance, download all data in a torrent to a single file, or to a │ │ │ │ -number of fixed size sector aligned files, regardless of the number │ │ │ │ -and sizes of the files in the torrent.

      │ │ │ │ -

      The new specified file_storage must have the exact same size as │ │ │ │ -the current one.

      Declared in "libtorrent/session_handle.hpp"

      │ │ │ │ -

      this class provides a non-owning handle to a session and a subset of the │ │ │ │ -interface of the session class. If the underlying session is destructed │ │ │ │ -any handle to it will no longer be valid. is_valid() will return false and │ │ │ │ -any operation on it will throw a system_error exception, with error code │ │ │ │ -invalid_session_handle.

      │ │ │ │ -
      │ │ │ │ -

      Note

      │ │ │ │ -

      these calls are potentially expensive and won't scale well with │ │ │ │ -lots of torrents. If you're concerned about performance, consider │ │ │ │ -using post_torrent_updates() instead.

      │ │ │ │ -
      │ │ │ │ -

      get_torrent_status returns a vector of the torrent_status for │ │ │ │ -every torrent which satisfies pred, which is a predicate function │ │ │ │ -which determines if a torrent should be included in the returned set │ │ │ │ -or not. Returning true means it should be included and false means │ │ │ │ -excluded. The flags argument is the same as to │ │ │ │ -torrent_handle::status(). Since pred is guaranteed to be │ │ │ │ -called for every torrent, it may be used to count the number of │ │ │ │ -torrents of different categories as well.

      │ │ │ │ -

      refresh_torrent_status takes a vector of torrent_status structs │ │ │ │ -(for instance the same vector that was returned by │ │ │ │ -get_torrent_status() ) and refreshes the status based on the │ │ │ │ -handle member. It is possible to use this function by first │ │ │ │ -setting up a vector of default constructed torrent_status objects, │ │ │ │ -only initializing the handle member, in order to request the │ │ │ │ -torrent status for multiple torrents in a single call. This can save a │ │ │ │ -significant amount of time if you have a lot of torrents.

      │ │ │ │ -

      Any torrent_status object whose handle member is not referring to │ │ │ │ -a valid torrent are ignored.

      │ │ │ │ -

      The intended use of these functions is to start off by calling │ │ │ │ -get_torrent_status() to get a list of all torrents that match your │ │ │ │ -criteria. Then call refresh_torrent_status() on that list. This │ │ │ │ -will only refresh the status for the torrents in your list, and thus │ │ │ │ -ignore all other torrents you might be running. This may save a │ │ │ │ -significant amount of time, especially if the number of torrents you're │ │ │ │ -interested in is small. In order to keep your list of interested │ │ │ │ -torrents up to date, you can either call get_torrent_status() from │ │ │ │ -time to time, to include torrents you might have become interested in │ │ │ │ -since the last time. In order to stop refreshing a certain torrent, │ │ │ │ -simply remove it from the list.

      │ │ │ │ -
      │ │ │ │ -void post_torrent_updates (status_flags_t flags = status_flags_t::all());
│ │ │ │ -
      │ │ │ │ -

      This functions instructs the session to post the state_update_alert, │ │ │ │ -containing the status of all torrents whose state changed since the │ │ │ │ -last time this function was called.

      │ │ │ │ -

      Only torrents who has the state subscription flag set will be │ │ │ │ -included. This flag is on by default. See add_torrent_params. │ │ │ │ -the flags argument is the same as for torrent_handle::status(). │ │ │ │ -see status_flags_t in torrent_handle.

      find_torrent() looks for a torrent with the given info-hash. In │ │ │ │ -case there is such a torrent in the session, a torrent_handle to that │ │ │ │ -torrent is returned. In case the torrent cannot be found, an invalid │ │ │ │ -torrent_handle is returned.

│ │ │ │ -torrent_handle add_torrent (add_torrent_params const& params);
│ │ │ │ -
      │ │ │ │ -

      You add torrents through the add_torrent() function where you give an │ │ │ │ -object with all the parameters. The add_torrent() overloads will block │ │ │ │ -until the torrent has been added (or failed to be added) and returns │ │ │ │ -an error code and a torrent_handle. In order to add torrents more │ │ │ │ -efficiently, consider using async_add_torrent() which returns │ │ │ │ -immediately, without waiting for the torrent to add. Notification of │ │ │ │ -the torrent being added is sent as add_torrent_alert.

      │ │ │ │ -

      The save_path field in add_torrent_params must be set to a valid │ │ │ │ -path where the files for the torrent will be saved. Even when using a │ │ │ │ -custom storage, this needs to be set to something. If the save_path │ │ │ │ -is empty, the call to add_torrent() will throw a system_error │ │ │ │ -exception.

      │ │ │ │ -

      The overload that does not take an error_code throws an exception on │ │ │ │ -error and is not available when building without exception support. │ │ │ │ -The torrent_handle returned by add_torrent() can be used to retrieve │ │ │ │ -information about the torrent's progress, its peers etc. It is also │ │ │ │ -used to abort a torrent.

      │ │ │ │ -

      If the torrent you are trying to add already exists in the session (is │ │ │ │ -either queued for checking, being checked or downloading) │ │ │ │ -add_torrent() will throw system_error which derives from │ │ │ │ -std::exception unless duplicate_is_error is set to false. In that │ │ │ │ -case, add_torrent() will return the handle to the existing torrent.

      │ │ │ │ -

      The add_torrent_params class has a flags field. It can be used to │ │ │ │ -control what state the new torrent will be added in. Common flags to │ │ │ │ -want to control are torrent_flags::paused and │ │ │ │ -torrent_flags::auto_managed. In order to add a magnet link that will │ │ │ │ -just download the metadata, but no payload, set the │ │ │ │ -torrent_flags::upload_mode flag.

      │ │ │ │ -

      Special consideration has to be taken when adding hybrid torrents │ │ │ │ -(i.e. torrents that are BitTorrent v2 torrents that are backwards │ │ │ │ -compatible with v1). For more details, see BitTorrent v2 torrents.

      │ │ │ │ -void pause ();
│ │ │ │ -bool is_paused () const;
│ │ │ │ -void resume ();
│ │ │ │ -
      │ │ │ │ -

      Pausing the session has the same effect as pausing every torrent in │ │ │ │ -it, except that torrents will not be resumed by the auto-manage │ │ │ │ -mechanism. Resuming will restore the torrents to their previous paused │ │ │ │ -state. i.e. the session pause state is separate from the torrent pause │ │ │ │ -state. A torrent is inactive if it is paused or if the session is │ │ │ │ -paused.

      set_dht_storage set a dht custom storage constructor function │ │ │ │ -to be used internally when the dht is created.

      │ │ │ │ -

      Since the dht storage is a critical component for the dht behavior, │ │ │ │ -this function will only be effective the next time the dht is started. │ │ │ │ -If you never touch this feature, a default map-memory based storage │ │ │ │ -is used.

      │ │ │ │ -

      If you want to make sure the dht is initially created with your │ │ │ │ -custom storage, create a session with the setting │ │ │ │ -settings_pack::enable_dht to false, set your constructor function │ │ │ │ -and call apply_settings with settings_pack::enable_dht to true.

The callback function is called from within │ │ │ │ -the libtorrent network thread once we've found where to store the blob, │ │ │ │ -possibly with the current value stored under the key. │ │ │ │ -The values passed to the callback functions are:

      │ │ │ │ -
      │ │ │ │ -
      entry& value
      │ │ │ │ -
      the current value stored under the key (may be empty). Also expected │ │ │ │ -to be set to the value to be stored by the function.
      │ │ │ │ -
      std::array<char,64>& signature
      │ │ │ │ -
      the signature authenticating the current value. This may be zeros │ │ │ │ -if there is currently no value stored. The function is expected to │ │ │ │ -fill in this buffer with the signature of the new value to store. │ │ │ │ -To generate the signature, you may want to use the │ │ │ │ -sign_mutable_item function.
      │ │ │ │ -
      std::int64_t& seq
      │ │ │ │ -
      current sequence number. May be zero if there is no current value. │ │ │ │ -The function is expected to set this to the new sequence number of │ │ │ │ -the value that is to be stored. Sequence numbers must be monotonically │ │ │ │ -increasing. Attempting to overwrite a value with a lower or equal │ │ │ │ -sequence number will fail, even if the signature is correct.

      Since the callback function cb is called from within libtorrent, │ │ │ │ -it is critical to not perform any blocking operations. Ideally not │ │ │ │ -even locking a mutex. Pass any data required for this function along │ │ │ │ -with the function object's context and make the function entirely │ │ │ │ -self-contained. The only reason data blob's value is computed │ │ │ │ -via a function instead of just passing in the new value is to avoid │ │ │ │ -race conditions. If you want to update the value in the DHT, you │ │ │ │ -must first retrieve it, then modify it, then write it back. The way │ │ │ │ -the DHT works, it is natural to always do a lookup before storing and │ │ │ │ -calling the callback in between is convenient.

│ │ │ │ -void set_peer_class_filter (ip_filter const& f);
│ │ │ │ -
      │ │ │ │ -

      Sets the peer class filter for this session. All new peer connections │ │ │ │ -will take this into account and be added to the peer classes specified │ │ │ │ -by this filter, based on the peer's IP address.

      │ │ │ │ -

      The ip-filter essentially maps an IP -> uint32. Each bit in that 32 │ │ │ │ -bit integer represents a peer class. The least significant bit │ │ │ │ -represents class 0, the next bit class 1 and so on.

      │ │ │ │ -

      For more info, see ip_filter.

      │ │ │ │ -

      For example, to make all peers in the range 200.1.1.0 - 200.1.255.255 │ │ │ │ -belong to their own peer class, apply the following filter:

      │ │ │ │ -
      │ │ │ │ -ip_filter f = ses.get_peer_class_filter();

│ │ │ │ -ses.set_peer_class_filter(f);
│ │ │ │ -
      │ │ │ │ -

      This setting only applies to new connections, it won't affect existing │ │ │ │ -peer connections.

      │ │ │ │ -

      This function is limited to only peer class 0-31, since there are only │ │ │ │ -32 bits in the IP range mapping. Only the set bits matter; no peer │ │ │ │ -class will be removed from a peer as a result of this call, peer │ │ │ │ -classes are only added.

      │ │ │ │ -

      The peer_class argument cannot be greater than 31. The bitmasks │ │ │ │ -representing peer classes in the peer_class_filter are 32 bits.

      │ │ │ │ -

      The get_peer_class_filter() function returns the current filter.

      This call dereferences the reference count of the specified peer │ │ │ │ -class. When creating a peer class it's automatically referenced by 1. │ │ │ │ -If you want to recycle a peer class, you may call this function. You │ │ │ │ -may only call this function once per peer class you create. │ │ │ │ -Calling it more than once for the same class will lead to memory │ │ │ │ -corruption.

      │ │ │ │ -
      │ │ │ │ -void remove_torrent (const torrent_handle&, remove_flags_t = {});
│ │ │ │ -
      │ │ │ │ -

      remove_torrent() will close all peer connections associated with │ │ │ │ -the torrent and tell the tracker that we've stopped participating in │ │ │ │ -the swarm. This operation cannot fail. When it completes, you will │ │ │ │ -receive a torrent_removed_alert.

      │ │ │ │ -

      remove_torrent() is non-blocking, but will remove the torrent from the │ │ │ │ -session synchronously. Calling session_handle::add_torrent() immediately │ │ │ │ -afterward with the same torrent will succeed. Note that this creates a │ │ │ │ -new handle which is not equal to the removed one.

      │ │ │ │ -

      The optional second argument options can be used to delete all the │ │ │ │ -files downloaded by this torrent. To do so, pass in the value │ │ │ │ -session_handle::delete_files. Once the torrent is deleted, a │ │ │ │ -torrent_deleted_alert is posted.

      │ │ │ │ -

      The torrent_handle remains valid for some time after remove_torrent() is │ │ │ │ -called. It will become invalid only after all libtorrent tasks (such as │ │ │ │ -I/O tasks) release their references to the torrent. Until this happens, │ │ │ │ -torrent_handle::is_valid() will return true, and other calls such │ │ │ │ -as torrent_handle::status() will succeed. Because of this, and because │ │ │ │ -remove_torrent() is non-blocking, the following sequence usually │ │ │ │ -succeeds (does not throw system_error): │ │ │ │ -.. code:: c++

      Note that when a queued or downloading torrent is removed, its position │ │ │ │ -in the download queue is vacated and every subsequent torrent in the │ │ │ │ -queue has their queue positions updated. This can potentially cause a │ │ │ │ -large state_update to be posted.

│ │ │ │ -void set_alert_notify (std::function<void()> const& fun);
│ │ │ │ -void pop_alerts (std::vector<alert*>* alerts);
│ │ │ │ -
      │ │ │ │ -

      Alerts is the main mechanism for libtorrent to report errors and │ │ │ │ -events. pop_alerts fills in the vector passed to it with pointers │ │ │ │ -to new alerts. The session still owns these alerts and they will stay │ │ │ │ -valid until the next time pop_alerts is called. You may not delete │ │ │ │ -the alert objects.

      │ │ │ │ -

      It is safe to call pop_alerts from multiple different threads, as │ │ │ │ -long as the alerts themselves are not accessed once another thread │ │ │ │ -calls pop_alerts. Doing this requires manual synchronization │ │ │ │ -between the popping threads.

      │ │ │ │ -

      wait_for_alert will block the current thread for max_wait time │ │ │ │ -duration, or until another alert is posted. If an alert is available │ │ │ │ -at the time of the call, it returns immediately. The returned alert │ │ │ │ -pointer is the head of the alert queue. wait_for_alert does not │ │ │ │ -pop alerts from the queue, it merely peeks at it. The returned alert │ │ │ │ -will stay valid until pop_alerts is called twice. The first time │ │ │ │ -will pop it and the second will free it.

      │ │ │ │ -

      If there is no alert in the queue and no alert arrives within the │ │ │ │ -specified timeout, wait_for_alert returns nullptr.

      │ │ │ │ -

      In the python binding, wait_for_alert takes the number of │ │ │ │ -milliseconds to wait as an integer.

      │ │ │ │ -

      The alert queue in the session will not grow indefinitely. Make sure │ │ │ │ -to pop periodically to not miss notifications. To control the max │ │ │ │ -number of alerts that's queued by the session, see │ │ │ │ -settings_pack::alert_queue_size.

      │ │ │ │ -

      Some alerts are considered so important that they are posted even when │ │ │ │ -the alert queue is full. Some alerts are considered mandatory and cannot │ │ │ │ -be disabled by the alert_mask. For instance, │ │ │ │ -save_resume_data_alert and save_resume_data_failed_alert are always │ │ │ │ -posted, regardless of the alert mask.

      │ │ │ │ -

      To control which alerts are posted, set the alert_mask │ │ │ │ -(settings_pack::alert_mask).

      │ │ │ │ -

      If the alert queue fills up to the point where alerts are dropped, this │ │ │ │ -will be indicated by a alerts_dropped_alert, which contains a bitmask │ │ │ │ -of which types of alerts were dropped. Generally it is a good idea to │ │ │ │ -make sure the alert queue is large enough, the alert_mask doesn't have │ │ │ │ -unnecessary categories enabled and to call pop_alert() frequently, to │ │ │ │ -avoid alerts being dropped.

      │ │ │ │ -

      the set_alert_notify function lets the client set a function object │ │ │ │ -to be invoked every time the alert queue goes from having 0 alerts to │ │ │ │ -1 alert. This function is called from within libtorrent, it may be the │ │ │ │ -main thread, or it may be from within a user call. The intention of │ │ │ │ -of the function is that the client wakes up its main thread, to poll │ │ │ │ -for more alerts using pop_alerts(). If the notify function fails │ │ │ │ -to do so, it won't be called again, until pop_alerts is called for │ │ │ │ -some other reason. For instance, it could signal an eventfd, post a │ │ │ │ -message to an HWND or some other main message pump. The actual │ │ │ │ -retrieval of alerts should not be done in the callback. In fact, the │ │ │ │ -callback should not block. It should not perform any expensive work. │ │ │ │ -It really should just notify the main application thread.

      │ │ │ │ -

      The type of an alert is returned by the polymorphic function │ │ │ │ -alert::type() but can also be queries from a concrete type via │ │ │ │ -T::alert_type, as a static constant.

      │ │ │ │ -

      The add_torrent_params contains all the information in a .torrent file │ │ │ │ -along with all information necessary to add that torrent to a session. │ │ │ │ -The key fields when adding a torrent are:

      │ │ │ │ -
        │ │ │ │ -
      • ti - the immutable info-dict part of the torrent
        • │ │ │ │ -
      • info_hash - when you don't have the metadata (.torrent file). This │ │ │ │ -uniquely identifies the torrent and can validate the info-dict when │ │ │ │ -received from the swarm.
        • │ │ │ │ -
      │ │ │ │ -

      In order to add a torrent to a session, one of those fields must be set │ │ │ │ -in addition to save_path. The add_torrent_params object can then be │ │ │ │ -passed into one of the session::add_torrent() overloads or │ │ │ │ -session::async_add_torrent().

      │ │ │ │ -

      If you only specify the info-hash, the torrent file will be downloaded │ │ │ │ -from peers, which requires them to support the metadata extension. For │ │ │ │ -the metadata extension to work, libtorrent must be built with extensions │ │ │ │ -enabled (TORRENT_DISABLE_EXTENSIONS must not be defined). It also │ │ │ │ -takes an optional name argument. This may be left empty in case no │ │ │ │ -name should be assigned to the torrent. In case it's not, the name is │ │ │ │ -used for the torrent as long as it doesn't have metadata. See │ │ │ │ -torrent_handle::name.

      │ │ │ │ -

      The add_torrent_params is also used when requesting resume data for a │ │ │ │ -torrent. It can be saved to and restored from a file and added back to a │ │ │ │ -new session. For serialization and de-serialization of │ │ │ │ -add_torrent_params objects, see read_resume_data() and │ │ │ │ -write_resume_data().

      │ │ │ │ -

      The add_torrent_params is also used to represent a parsed .torrent │ │ │ │ -file. It can be loaded via load_torrent_file(), load_torrent_buffer() and │ │ │ │ -load_torrent_parsed(). It can be saved via write_torrent_file().

      The pop_alerts() function on session is the main interface for retrieving │ │ │ │ -alerts (warnings, messages and errors from libtorrent). If no alerts have │ │ │ │ -been posted by libtorrent pop_alerts() will return an empty list.

      │ │ │ │ -

      By default, only errors are reported. settings_pack::alert_mask can be │ │ │ │ -used to specify which kinds of events should be reported. The alert mask is │ │ │ │ -a combination of the alert_category_t flags in the alert class.

      │ │ │ │ -

      Every alert belongs to one or more category. There is a cost associated with │ │ │ │ -posting alerts. Only alerts that belong to an enabled category are │ │ │ │ -posted. Setting the alert bitmask to 0 will disable all alerts (except those │ │ │ │ -that are non-discardable). Alerts that are responses to API calls such as │ │ │ │ -save_resume_data() and post_session_stats() are non-discardable and will be │ │ │ │ -posted even if their category is disabled.

      │ │ │ │ -

      There are other alert base classes that some alerts derive from, all the │ │ │ │ -alerts that are generated for a specific torrent are derived from │ │ │ │ -torrent_alert, and tracker events derive from tracker_alert.

      │ │ │ │ -

      Alerts returned by pop_alerts() are only valid until the next call to │ │ │ │ -pop_alerts(). You may not copy an alert object to access it after the next │ │ │ │ -call to pop_alerts(). Internal members of alerts also become invalid once │ │ │ │ -pop_alerts() is called again.

      torrent_removed_alert

      │ │ │ │ -

      Declared in "libtorrent/alert_types.hpp"

      │ │ │ │ -

      The torrent_removed_alert is posted whenever a torrent is removed. Since │ │ │ │ -the torrent handle in its base class will usually be invalid (since the torrent │ │ │ │ -is already removed) it has the info hash as a member, to identify it. │ │ │ │ -It's posted when the alert_category::status bit is set in the alert_mask.

      │ │ │ │ -

      Note that the handle remains valid for some time after │ │ │ │ -torrent_removed_alert is posted, as long as some internal libtorrent │ │ │ │ -task (such as an I/O task) refers to it. Additionally, other alerts like │ │ │ │ -save_resume_data_alert may be posted after torrent_removed_alert. │ │ │ │ -To synchronize on whether the torrent has been removed or not, call │ │ │ │ -torrent_handle::in_session(). This will return true before │ │ │ │ -torrent_removed_alert is posted, and false afterward.

      │ │ │ │ -

      Even though the handle member doesn't point to an existing torrent anymore, │ │ │ │ -it is still useful for comparing to other handles, which may also no │ │ │ │ -longer point to existing torrents, but to the same non-existing torrents.

      │ │ │ │ -

      The torrent_handle acts as a weak_ptr, even though its object no │ │ │ │ -longer exists, it can still compare equal to another weak pointer which │ │ │ │ -points to the same non-existent object.

      outstanding_disk_buffer_limit_reached0This warning means that the number of bytes queued to be written to disk │ │ │ │ -exceeds the max disk byte queue setting (settings_pack::max_queued_disk_bytes). │ │ │ │ -This might restrict the download rate, by not queuing up enough write jobs │ │ │ │ -to the disk I/O thread. When this alert is posted, peer connections are │ │ │ │ -temporarily stopped from downloading, until the queued disk bytes have fallen │ │ │ │ -below the limit again. Unless your max_queued_disk_bytes setting is already │ │ │ │ -high, you might want to increase it to get better performance.
      outstanding_request_limit_reached1This is posted when libtorrent would like to send more requests to a peer, │ │ │ │ -but it's limited by settings_pack::max_out_request_queue. The queue length │ │ │ │ -libtorrent is trying to achieve is determined by the download rate and the │ │ │ │ -assumed round-trip-time (settings_pack::request_queue_time). The assumed │ │ │ │ -round-trip-time is not limited to just the network RTT, but also the remote disk │ │ │ │ -access time and message handling time. It defaults to 3 seconds. The target number │ │ │ │ -of outstanding requests is set to fill the bandwidth-delay product (assumed RTT │ │ │ │ -times download rate divided by number of bytes per request). When this alert │ │ │ │ -is posted, there is a risk that the number of outstanding requests is too low │ │ │ │ -and limits the download rate. You might want to increase the max_out_request_queue │ │ │ │ -setting.
      upload_limit_too_low2This warning is posted when the amount of TCP/IP overhead is greater than the │ │ │ │ -upload rate limit. When this happens, the TCP/IP overhead is caused by a much │ │ │ │ -faster download rate, triggering TCP ACK packets. These packets eat into the │ │ │ │ -rate limit specified to libtorrent. When the overhead traffic is greater than │ │ │ │ -the rate limit, libtorrent will not be able to send any actual payload, such │ │ │ │ -as piece requests. This means the download rate will suffer, and new requests │ │ │ │ -can be sent again. There will be an equilibrium where the download rate, on │ │ │ │ -average, is about 20 times the upload rate limit. If you want to maximize the │ │ │ │ -download rate, increase the upload rate limit above 5% of your download capacity.
      download_limit_too_low3This is the same warning as upload_limit_too_low but referring to the download │ │ │ │ -limit instead of upload. This suggests that your download rate limit is much lower │ │ │ │ -than your upload capacity. Your upload rate will suffer. To maximize upload rate, │ │ │ │ -make sure your download rate limit is above 5% of your upload capacity.
      send_buffer_watermark_too_low4

      We're stalled on the disk. We want to write to the socket, and we can write │ │ │ │ -but our send buffer is empty, waiting to be refilled from the disk. │ │ │ │ -This either means the disk is slower than the network connection │ │ │ │ -or that our send buffer watermark is too small, because we can │ │ │ │ -send it all before the disk gets back to us. │ │ │ │ -The number of bytes that we keep outstanding, requested from the disk, is calculated │ │ │ │ -as follows:

      │ │ │ │ -
      │ │ │ │ -min(512, max(upload_rate * send_buffer_watermark_factor / 100, send_buffer_watermark))
│ │ │ │ -
      │ │ │ │ -

      If you receive this alert, you might want to either increase your send_buffer_watermark │ │ │ │ -or send_buffer_watermark_factor.

      │ │ │ │ -
      too_many_optimistic_unchoke_slots5If the half (or more) of all upload slots are set as optimistic unchoke slots, this │ │ │ │ -warning is issued. You probably want more regular (rate based) unchoke slots.
      too_high_disk_queue_limit6If the disk write queue ever grows larger than half of the cache size, this warning │ │ │ │ -is posted. The disk write queue eats into the total disk cache and leaves very little │ │ │ │ -left for the actual cache. This causes the disk cache to oscillate in evicting large │ │ │ │ -portions of the cache before allowing peers to download any more, onto the disk write │ │ │ │ -queue. Either lower max_queued_disk_bytes or increase cache_size.

      session_stats_alert

      │ │ │ │ -

      Declared in "libtorrent/alert_types.hpp"

      │ │ │ │ -

      The session_stats_alert is posted when the user requests session statistics by │ │ │ │ -calling post_session_stats() on the session object. This alert does not │ │ │ │ -have a category, since it's only posted in response to an API call. It │ │ │ │ -is not subject to the alert_mask filter.

      │ │ │ │ -

      the message() member function returns a string representation of the values that │ │ │ │ -properly match the line returned in session_stats_header_alert::message().

      │ │ │ │ -

      this specific output is parsed by tools/parse_session_stats.py │ │ │ │ -if this is changed, that parser should also be changed

      │ │ │ │ -

      An array are a mix of counters and gauges, which meanings can be │ │ │ │ -queries via the session_stats_metrics() function on the session. The │ │ │ │ -mapping from a specific metric to an index into this array is constant │ │ │ │ -for a specific version of libtorrent, but may differ for other │ │ │ │ -versions. The intended usage is to request the mapping, i.e. call │ │ │ │ -session_stats_metrics(), once on startup, and then use that mapping to │ │ │ │ -interpret these values throughout the process' runtime.

      Adds a file to the file storage. The add_file_borrow version │ │ │ │ -expects that filename is the file name (without a path) of │ │ │ │ -the file that's being added. │ │ │ │ -This memory is borrowed, i.e. it is the caller's │ │ │ │ -responsibility to make sure it stays valid throughout the lifetime │ │ │ │ -of this file_storage object or any copy of it. The same thing applies │ │ │ │ -to filehash, which is an optional pointer to a 20 byte binary │ │ │ │ -SHA-1 hash of the file.

      │ │ │ │ -

      if filename is empty, the filename from path is used and not │ │ │ │ -borrowed.

      │ │ │ │ -

      The path argument is the full path (in the torrent file) to │ │ │ │ -the file to add. Note that this is not supposed to be an absolute │ │ │ │ -path, but it is expected to include the name of the torrent as the │ │ │ │ -first path element.

      │ │ │ │ -

      file_size is the size of the file in bytes.

      │ │ │ │ -

      The file_flags argument sets attributes on the file. The file │ │ │ │ -attributes is an extension and may not work in all bittorrent clients.

      │ │ │ │ -

      For possible file attributes, see file_storage::flags_t.

      │ │ │ │ -

      The mtime argument is optional and can be set to 0. If non-zero, │ │ │ │ -it is the posix time of the last modification time of this file.

      │ │ │ │ -

      symlink_path is the path the file is a symlink to. To make this a │ │ │ │ -symlink you also need to set the file_storage::flag_symlink file flag.

      │ │ │ │ -

      root_hash is an optional pointer to a 32 byte SHA-256 hash, being │ │ │ │ -the merkle tree root hash for this file. This is only used for v2 │ │ │ │ -torrents. If the root hash is specified for one file, it has to │ │ │ │ -be specified for all, otherwise this function will fail. │ │ │ │ -Note that the buffer root_hash points to must out-live the │ │ │ │ -file_storage object, it will not be copied. This parameter is only │ │ │ │ -used when loading torrents, that already have their file hashes │ │ │ │ -computed. When creating torrents, the file hashes will be computed by │ │ │ │ -the piece hashes.

      │ │ │ │ -

      If more files than one are added, certain restrictions to their paths │ │ │ │ -apply. In a multi-file file storage (torrent), all files must share │ │ │ │ -the same root directory.

      │ │ │ │ -

      That is, the first path element of all files must be the same. │ │ │ │ -This shared path element is also set to the name of the torrent. It │ │ │ │ -can be changed by calling set_name.

      │ │ │ │ -

      The overloads that take an error_code reference will report failures │ │ │ │ -via that variable, otherwise system_error is thrown.

      libtorrent has a plugin interface for implementing extensions to the protocol. │ │ │ │ -These can be general extensions for transferring metadata or peer exchange │ │ │ │ -extensions, or it could be used to provide a way to customize the protocol │ │ │ │ -to fit a particular (closed) network.

      │ │ │ │ -

      In short, the plugin interface makes it possible to:

      │ │ │ │ -
        │ │ │ │ -
      • register extension messages (sent in the extension handshake), see │ │ │ │ -extensions.
        • │ │ │ │ -
      • add data and parse data from the extension handshake.
        • │ │ │ │ -
      • send extension messages and standard bittorrent messages.
        • │ │ │ │ -
      • override or block the handling of standard bittorrent messages.
        • │ │ │ │ -
      • save and restore state via the session state
        • │ │ │ │ -
      • see all alerts that are posted
        • │ │ │ │ -
      │ │ │ │ -
      │ │ │ │ -
      │ │ │ │ -

      a word of caution

      │ │ │ │ -

      Writing your own plugin is a very easy way to introduce serious bugs such as │ │ │ │ -dead locks and race conditions. Since a plugin has access to internal │ │ │ │ -structures it is also quite easy to sabotage libtorrent's operation.

      │ │ │ │ -

      All the callbacks are always called from the libtorrent network thread. In │ │ │ │ -case portions of your plugin are called from other threads, typically the main │ │ │ │ -thread, you cannot use any of the member functions on the internal structures │ │ │ │ -in libtorrent, since those require being called from the libtorrent network │ │ │ │ -thread . Furthermore, you also need to synchronize your own shared data │ │ │ │ -within the plugin, to make sure it is not accessed at the same time from the │ │ │ │ -libtorrent thread (through a callback). If you need to send out a message │ │ │ │ -from another thread, it is advised to use an internal queue, and do the │ │ │ │ -actual sending in tick().

      │ │ │ │ -

      Since the plugin interface gives you easy access to internal structures, it │ │ │ │ -is not supported as a stable API. Plugins should be considered specific to a │ │ │ │ -specific version of libtorrent. Although, in practice the internals mostly │ │ │ │ -don't change that dramatically.

      │ │ │ │ -
      │ │ │ │ -
      │ │ │ │ -

      plugin-interface

      │ │ │ │ -

      The plugin interface consists of three base classes that the plugin may │ │ │ │ -implement. These are called plugin, torrent_plugin and peer_plugin. │ │ │ │ -They are found in the <libtorrent/extensions.hpp> header.

      │ │ │ │ -

      These plugins are instantiated for each session, torrent and possibly each peer, │ │ │ │ -respectively.

      │ │ │ │ -

      For plugins that only need per torrent state, it is enough to only implement │ │ │ │ -torrent_plugin and pass a constructor function or function object to │ │ │ │ -session::add_extension() or torrent_handle::add_extension() (if the │ │ │ │ -torrent has already been started and you want to hook in the extension at │ │ │ │ -run-time).

      │ │ │ │ -

      The signature of the function is:

      │ │ │ │ -
      │ │ │ │ -std::shared_ptr<torrent_plugin> (*)(torrent_handle const&, client_data_t);
│ │ │ │ -
      │ │ │ │ -

      The second argument is the userdata passed to session::add_torrent() or │ │ │ │ -torrent_handle::add_extension().

      │ │ │ │ -

      The function should return a std::shared_ptr<torrent_plugin> which │ │ │ │ -may or may not be 0. If it is a nullptr, the extension is simply ignored │ │ │ │ -for this torrent. If it is a valid pointer (to a class inheriting │ │ │ │ -torrent_plugin), it will be associated with this torrent and callbacks │ │ │ │ -will be made on torrent events.

      │ │ │ │ -

      For more elaborate plugins which require session wide state, you would │ │ │ │ -implement plugin, construct an object (in a std::shared_ptr) and pass │ │ │ │ -it in to session::add_extension().

      │ │ │ │ -
      │ │ │ │ -
      │ │ │ │ -

      custom alerts

      │ │ │ │ -

      Since plugins are running within internal libtorrent threads, one convenient │ │ │ │ -way to communicate with the client is to post custom alerts.

      │ │ │ │ -

      The expected interface of any alert, apart from deriving from the alert │ │ │ │ -base class, looks like this:

      │ │ │ │ -
      │ │ │ │ -static const int alert_type = <unique alert ID>;
│ │ │ │ -virtual int type() const { return alert_type; }
│ │ │ │ -
│ │ │ │ -virtual std::string message() const;
│ │ │ │ -
│ │ │ │ -static const alert_category_t static_category = <bitmask of alert::category_t flags>;
│ │ │ │ -virtual alert_category_t category() const { return static_category; }
│ │ │ │ -
│ │ │ │ -virtual char const* what() const { return <string literal of the name of this alert>; }
│ │ │ │ -
      │ │ │ │ -

      The alert_type is used for the type-checking in alert_cast. It must │ │ │ │ -not collide with any other alert. The built-in alerts in libtorrent will │ │ │ │ -not use alert type IDs greater than user_alert_id. When defining your │ │ │ │ -own alert, make sure it's greater than this constant.

      │ │ │ │ -

      type() is the run-time equivalence of the alert_type.

      │ │ │ │ -

      The message() virtual function is expected to construct a useful │ │ │ │ -string representation of the alert and the event or data it represents. │ │ │ │ -Something convenient to put in a log file for instance.

      │ │ │ │ -

      clone() is used internally to copy alerts. The suggested implementation │ │ │ │ -of simply allocating a new instance as a copy of *this is all that's │ │ │ │ -expected.

      │ │ │ │ -

      The static category is required for checking whether or not the category │ │ │ │ -for a specific alert is enabled or not, without instantiating the alert. │ │ │ │ -The category virtual function is the run-time equivalence.

      │ │ │ │ -

      The what() virtual function may simply be a string literal of the class │ │ │ │ -name of your alert.

      │ │ │ │ -

      For more information, see the alert section.

      Declared in "libtorrent/extensions.hpp"

      │ │ │ │ -

      Torrent plugins are associated with a single torrent and have a number │ │ │ │ -of functions called at certain events. Many of its functions have the │ │ │ │ -ability to change or override the default libtorrent behavior.

      │ │ │ │ -

      new_connection()

      │ │ │ │ -
      │ │ │ │ -virtual std::shared_ptr<peer_plugin> new_connection (peer_connection_handle const&);
│ │ │ │ -
      │ │ │ │ -

      This function is called each time a new peer is connected to the torrent. You │ │ │ │ -may choose to ignore this by just returning a default constructed │ │ │ │ -shared_ptr (in which case you don't need to override this member │ │ │ │ -function).

      │ │ │ │ -

      If you need an extension to the peer connection (which most plugins do) you │ │ │ │ -are supposed to return an instance of your peer_plugin class. Which in │ │ │ │ -turn will have its hook functions called on event specific to that peer.

      │ │ │ │ -

      The peer_connection_handle will be valid as long as the shared_ptr │ │ │ │ -is being held by the torrent object. So, it is generally a good idea to not │ │ │ │ -keep a shared_ptr to your own peer_plugin. If you want to keep references │ │ │ │ -to it, use weak_ptr.

      │ │ │ │ -

      If this function throws an exception, the connection will be closed.

│ │ │ │ -
      │ │ │ │ -

      These hooks are called when a piece passes the hash check or fails the hash │ │ │ │ -check, respectively. The index is the piece index that was downloaded. │ │ │ │ -It is possible to access the list of peers that participated in sending the │ │ │ │ -piece through the torrent and the piece_picker.

      │ │ │ │ -
      │ │ │ │ -virtual bool on_resume ();
│ │ │ │ -virtual bool on_pause ();
│ │ │ │ -
      │ │ │ │ -

      These hooks are called when the torrent is paused and resumed respectively. │ │ │ │ -The return value indicates if the event was handled. A return value of │ │ │ │ -true indicates that it was handled, and no other plugin after this one │ │ │ │ -will have this hook function called, and the standard handler will also not be │ │ │ │ -invoked. So, returning true effectively overrides the standard behavior of │ │ │ │ -pause or resume.

      │ │ │ │ -

      Note that if you call pause() or resume() on the torrent from your │ │ │ │ -handler it will recurse back into your handler, so in order to invoke the │ │ │ │ -standard handler, you have to keep your own state on whether you want standard │ │ │ │ -behavior or overridden behavior.

      │ │ │ │ +

      An HTTP(s) tracker requests to localhost (loopback) │ │ │ │ +must have the request path start with "/announce". This is the │ │ │ │ +conventional bittorrent tracker request. Any other HTTP(S) │ │ │ │ +tracker request to loopback will be rejected. This applies to │ │ │ │ +trackers that redirect to loopback as well.

      │ │ │ │ +

      Web seeds that end up on the client's local network (i.e. in a │ │ │ │ +private IP address range) may not include query string arguments. │ │ │ │ +This applies to web seeds redirecting to the local network as │ │ │ │ +well.

      when set to true, enables the attempt to use SetFileValidData() │ │ │ │ +to pre-allocate disk space. This system call will only work when │ │ │ │ +running with Administrator privileges on Windows, and so this │ │ │ │ +setting is only relevant in that scenario.

      When using a SOCKS5 proxy, UDP traffic is routed through the │ │ │ │ +proxy by sending a UDP ASSOCIATE command. If this option is true, │ │ │ │ +the UDP ASSOCIATE command will include the IP address and │ │ │ │ +listen port to the local UDP socket. This indicates to the proxy │ │ │ │ +which source endpoint to expect our packets from. The benefit is │ │ │ │ +that incoming packets can be forwarded correctly, before any │ │ │ │ +outgoing packets are sent. The risk is that if there's a NAT │ │ │ │ +between the client and the proxy, the IP address specified in the │ │ │ │ +protocol may not be valid from the proxy's point of view.

      tracker_receive_timeout is the number of seconds to wait to │ │ │ │ +receive any data from the tracker. If no data is received for this │ │ │ │ +number of seconds, the tracker will be considered as having timed │ │ │ │ +out. If a tracker is down, this is the kind of timeout that will │ │ │ │ +occur.

      stop_tracker_timeout is the number of seconds to wait when │ │ │ │ +sending a stopped message before considering a tracker to have │ │ │ │ +timed out. This is usually shorter, to make the client quit faster. │ │ │ │ +If the value is set to 0, the connections to trackers with the │ │ │ │ +stopped event are suppressed.

      this is the maximum number of bytes in a tracker response. If a │ │ │ │ +response size passes this number of bytes it will be rejected and │ │ │ │ +the connection will be closed. On gzipped responses this size is │ │ │ │ +measured on the uncompressed data. So, if you get 20 bytes of gzip │ │ │ │ +response that'll expand to 2 megabytes, it will be interrupted │ │ │ │ +before the entire response has been uncompressed (assuming the │ │ │ │ +limit is lower than 2 MiB).

      │ │ │ │ +

      the length of the request queue given in the number of seconds it │ │ │ │ +should take for the other end to send all the pieces. i.e. the │ │ │ │ +actual number of requests depends on the download rate and this │ │ │ │ +number.

      the number of outstanding block requests a peer is allowed to queue │ │ │ │ +up in the client. If a peer sends more requests than this (before │ │ │ │ +the first one has been sent) the last request will be dropped. the │ │ │ │ +higher this is, the faster upload speeds the client can get to a │ │ │ │ +single peer.

      nametypedefault
      max_out_request_queueint500
      │ │ │ │ +

      max_out_request_queue is the maximum number of outstanding │ │ │ │ +requests to send to a peer. This limit takes precedence over │ │ │ │ +request_queue_time. i.e. no matter the download speed, the │ │ │ │ +number of outstanding requests will never exceed this limit.

      │ │ │ │ +

      if a whole piece can be downloaded in this number of seconds, or │ │ │ │ +less, the peer_connection will prefer to request whole pieces at a │ │ │ │ +time from this peer. The benefit of this is to better utilize disk │ │ │ │ +caches by doing localized accesses and also to make it easier to │ │ │ │ +identify bad peers if a piece fails the hash check.

      │ │ │ │ +

      sets the upper limit on the total number of files this session will │ │ │ │ +keep open. The reason why files are left open at all is that some │ │ │ │ +anti virus software hooks on every file close, and scans the file │ │ │ │ +for viruses. deferring the closing of the files will be the │ │ │ │ +difference between a usable system and a completely hogged down │ │ │ │ +system.

      max_failcount is the maximum times we try to │ │ │ │ +connect to a peer before stop connecting again. If a │ │ │ │ +peer succeeds, the failure counter is reset. If a │ │ │ │ +peer is retrieved from a peer source (other than DHT) │ │ │ │ +the failcount is decremented by one, allowing another │ │ │ │ +try.

      max_queued_disk_bytes is the maximum number of bytes, to │ │ │ │ +be written to disk, that can wait in the disk I/O thread queue. │ │ │ │ +This queue is only for waiting for the disk I/O thread to receive │ │ │ │ +the job and either write it to disk or insert it in the write │ │ │ │ +cache.

      │ │ │ │ +

      send_buffer_low_watermark the minimum send buffer target size │ │ │ │ +(send buffer includes bytes pending being read from disk). For good │ │ │ │ +and snappy seeding performance, set this fairly high, to at least │ │ │ │ +fit a few blocks. This is essentially the initial window size which │ │ │ │ +will determine how fast we can ramp up the send rate

      │ │ │ │ +

      if the send buffer has fewer bytes than send_buffer_watermark, │ │ │ │ +we'll read another 16 kiB block onto it. If set too small, upload │ │ │ │ +rate capacity will suffer. If set too high, memory will be wasted. │ │ │ │ +The actual watermark may be lower than this in case the upload rate │ │ │ │ +is low, this is the upper limit.

      │ │ │ │ +

      the current upload rate to a peer is multiplied by this factor to │ │ │ │ +get the send buffer watermark. The factor is specified as a │ │ │ │ +percentage. i.e. 50 -> 0.5 This product is clamped to the │ │ │ │ +send_buffer_watermark setting to not exceed the max. For high │ │ │ │ +speed upload, this should be set to a greater value than 100. For │ │ │ │ +high capacity connections, setting this higher can improve upload │ │ │ │ +performance and disk throughput. Setting it too high may waste RAM │ │ │ │ +and create a bias towards read jobs over write jobs.

      choking_algorithm specifies which algorithm to use to determine │ │ │ │ +how many peers to unchoke. The unchoking algorithm for │ │ │ │ +downloading torrents is always "tit-for-tat", i.e. the peers we │ │ │ │ +download the fastest from are unchoked.

      │ │ │ │ +

      The options for choking algorithms are defined in the │ │ │ │ +choking_algorithm_t enum.

      │ │ │ │ +

      seed_choking_algorithm controls the seeding unchoke behavior. │ │ │ │ +i.e. How we select which peers to unchoke for seeding torrents. │ │ │ │ +Since a seeding torrent isn't downloading anything, the │ │ │ │ +tit-for-tat mechanism cannot be used.

      │ │ │ │ +
      │ │ │ │ +

      │ │ │ │ +
      Files are opened normally, with the OS caching reads and writes.
      │ │ │ │ +
      disable_os_cache
      │ │ │ │ +
      This opens all files in no-cache mode. This corresponds to the │ │ │ │ +OS not letting blocks for the files linger in the cache. This │ │ │ │ +makes sense in order to avoid the bittorrent client to │ │ │ │ +potentially evict all other processes' cache by simply handling │ │ │ │ +high throughput and large files. If libtorrent's read cache is │ │ │ │ +disabled, enabling this may reduce performance.
      │ │ │ │ +
      write_through
      │ │ │ │ +
      flush pieces to disk as they complete validation.
      │ │ │ │ +

      Warning

      │ │ │ │ +

      setting outgoing ports will limit the ability to keep │ │ │ │ +multiple connections to the same client, even for different │ │ │ │ +torrents. It is not recommended to change this setting.

      │ │ │ │ +
      │ │ │ │ +

      It is a range instead of a single port because of the problems with │ │ │ │ +failing to reconnect to peers if a previous socket to that peer and │ │ │ │ +port is in TIME_WAIT state.

      for auto managed torrents, these are the limits they are subject │ │ │ │ +to. If there are too many torrents some of the auto managed ones │ │ │ │ +will be paused until some slots free up. active_downloads and │ │ │ │ +active_seeds controls how many active seeding and downloading │ │ │ │ +torrents the queuing mechanism allows. The target number of active │ │ │ │ +torrents is min(active_downloads + active_seeds, active_limit). │ │ │ │ +active_downloads and active_seeds are upper limits on the │ │ │ │ +number of downloading torrents and seeding torrents respectively. │ │ │ │ +Setting the value to -1 means unlimited.

      │ │ │ │ +

      For example if there are 10 seeding torrents and 10 downloading │ │ │ │ +torrents, and active_downloads is 4 and active_seeds is 4, │ │ │ │ +there will be 4 seeds active and 4 downloading torrents. If the │ │ │ │ +settings are active_downloads = 2 and active_seeds = 4, │ │ │ │ +then there will be 2 downloading torrents and 4 seeding torrents │ │ │ │ +active. Torrents that are not auto managed are not counted against │ │ │ │ +these limits.

      │ │ │ │ +

      active_checking is the limit of number of simultaneous checking │ │ │ │ +torrents.

      │ │ │ │ +

      active_limit is a hard limit on the number of active (auto │ │ │ │ +managed) torrents. This limit also applies to slow torrents.

      active_lsd_limit is the max number of torrents to announce to │ │ │ │ +the local network over the local service discovery protocol.

      │ │ │ │ +

      You can have more torrents active, even though they are not │ │ │ │ +announced to the DHT, lsd or their tracker. If some peer knows │ │ │ │ +about you for any reason and tries to connect, it will still be │ │ │ │ +accepted, unless the torrent is paused, which means it won't accept │ │ │ │ +any connections.

      auto_scrape_interval is the number of seconds between scrapes │ │ │ │ +of queued torrents (auto managed and paused torrents). Auto managed │ │ │ │ +torrents that are paused, are scraped regularly in order to keep │ │ │ │ +track of their downloader/seed ratio. This ratio is used to │ │ │ │ +determine which torrents to seed and which to pause.

      │ │ │ │ +

      auto_scrape_min_interval is the minimum number of seconds │ │ │ │ +between any automatic scrape (regardless of torrent). In case there │ │ │ │ +are a large number of paused auto managed torrents, this puts a │ │ │ │ +limit on how often a scrape request is sent.

      tick_interval specifies the number of milliseconds between │ │ │ │ +internal ticks. This is the frequency with which bandwidth quota is │ │ │ │ +distributed to peers. It should not be more than one second (i.e. │ │ │ │ +1000 ms).

      share_mode_target specifies the target share ratio for share │ │ │ │ +mode torrents. If set to 3, we'll try to upload 3 │ │ │ │ +times as much as we download. Setting this very high, will make it │ │ │ │ +very conservative and you might end up not downloading anything │ │ │ │ +ever (and not affecting your share ratio).

      │ │ │ │ +

      utp_target_delay is the target delay for uTP sockets in │ │ │ │ +milliseconds. A high value will make uTP connections more │ │ │ │ +aggressive and cause longer queues in the upload bottleneck. It │ │ │ │ +cannot be too low, since the noise in the measurements would cause │ │ │ │ +it to send too slow. │ │ │ │ +utp_gain_factor is the number of bytes the uTP congestion │ │ │ │ +window can increase at the most in one RTT. │ │ │ │ +If this is set too high, the congestion controller reacts │ │ │ │ +too hard to noise and will not be stable, if it's set too low, it │ │ │ │ +will react slow to congestion and not back off as fast.

      │ │ │ │ +

      utp_min_timeout is the shortest allowed uTP socket timeout, │ │ │ │ +specified in milliseconds. The │ │ │ │ +timeout depends on the RTT of the connection, but is never smaller │ │ │ │ +than this value. A connection times out when every packet in a │ │ │ │ +window is lost, or when a packet is lost twice in a row (i.e. the │ │ │ │ +resent packet is lost as well).

      │ │ │ │ +

      The shorter the timeout is, the faster the connection will recover │ │ │ │ +from this situation, assuming the RTT is low enough. │ │ │ │ +utp_syn_resends is the number of SYN packets that are sent (and │ │ │ │ +timed out) before giving up and closing the socket. │ │ │ │ +utp_num_resends is the number of times a packet is sent (and │ │ │ │ +lost or timed out) before giving up and closing the connection. │ │ │ │ +utp_connect_timeout is the number of milliseconds of timeout │ │ │ │ +for the initial SYN packet for uTP connections. For each timed out │ │ │ │ +packet (in a row), the timeout is doubled. utp_loss_multiplier │ │ │ │ +controls how the congestion window is changed when a packet loss is │ │ │ │ +experienced. It's specified as a percentage multiplier for │ │ │ │ +cwnd. Do not change this value unless you know what you're doing. │ │ │ │ +Never set it higher than 100.

      mixed_mode_algorithmintsettings_pack::peer_proportional
      │ │ │ │ +

      The mixed_mode_algorithm determines how to treat TCP │ │ │ │ +connections when there are uTP connections. Since uTP is designed │ │ │ │ +to yield to TCP, there's an inherent problem when using swarms that │ │ │ │ +have both TCP and uTP connections. If nothing is done, uTP │ │ │ │ +connections would often be starved out for bandwidth by the TCP │ │ │ │ +connections. This mode is prefer_tcp. The peer_proportional │ │ │ │ +mode simply looks at the current throughput and rate limits all TCP │ │ │ │ +connections to their proportional share based on how many of the │ │ │ │ +connections are TCP. This works best if uTP connections are not │ │ │ │ +rate limited by the global rate limiter (which they aren't by │ │ │ │ +default).

If this is a high performance server which expects │ │ │ │ +to receive a lot of connections, or used in a simulator or test, it │ │ │ │ +might make sense to raise this number.

      control the settings for incoming and outgoing connections │ │ │ │ +respectively. see enc_policy enum for the available options. │ │ │ │ +Keep in mind that protocol encryption degrades performance in │ │ │ │ +several respects:

      │ │ │ │ +
        │ │ │ │ +
      1. It prevents "zero copy" disk buffers being sent to peers, since │ │ │ │ +each peer needs to mutate the data (i.e. encrypt it) the data │ │ │ │ +must be copied per peer connection rather than sending the same │ │ │ │ +buffer to multiple peers.
        2. │ │ │ │ +
      2. The encryption itself requires more CPU than plain bittorrent │ │ │ │ +protocol. The highest cost is the Diffie Hellman exchange on │ │ │ │ +connection setup.
        3. │ │ │ │ +
      3. The encryption handshake adds several round-trips to the │ │ │ │ +connection setup, and delays transferring data.

      This section describes the functions and classes that are used │ │ │ │ +to create torrent files. It is a layered API with low level classes │ │ │ │ +and higher level convenience functions. A torrent is created in 4 │ │ │ │ +steps:

      │ │ │ │ +
        │ │ │ │ +
      1. first the files that will be part of the torrent are determined.
        2. │ │ │ │ +
      2. the torrent properties are set, such as tracker url, web seeds, │ │ │ │ +DHT nodes etc.
        3. │ │ │ │ +
      3. Read through all the files in the torrent, SHA-1 all the data │ │ │ │ +and set the piece hashes.
        4. │ │ │ │ +
      4. The torrent is bencoded into a file or buffer.
        5. │ │ │ │ +
      │ │ │ │ +

      If there are a lot of files and or deep directory hierarchies to │ │ │ │ +traverse, step one can be time consuming.

      │ │ │ │ +

      Typically step 3 is by far the most time consuming step, since it │ │ │ │ +requires to read all the bytes from all the files in the torrent.

      │ │ │ │ +

      All of these classes and functions are declared by including │ │ │ │ +libtorrent/create_torrent.hpp.

      │ │ │ │ +

      │ │ │ │ +

      The piece_size is the size of each piece in bytes. It must be a │ │ │ │ +power of 2 and a minimum of 16 kiB. If a piece size of 0 is │ │ │ │ +specified, a piece_size will be set automatically. │ │ │ │ +Piece sizes greater than 128 MiB are considered unreasonable and will │ │ │ │ +be rejected (with an lt::system_error exception).

      The flags arguments specifies options for the torrent creation. It can │ │ │ │ +be any combination of the flags defined by create_flags_t.

      │ │ │ │ +

      The file_storage (fs) parameter defines the files, sizes and │ │ │ │ +their properties for the torrent to be created. Set this up first, │ │ │ │ +before passing it to the create_torrent constructor.

      │ │ │ │ +

      The overload that takes a torrent_info object will make a verbatim │ │ │ │ +copy of its info dictionary (to preserve the info-hash). The copy of │ │ │ │ +the info dictionary will be used by create_torrent::generate().

      This function will generate the .torrent file as a bencode tree, or a │ │ │ │ +bencoded into a buffer. │ │ │ │ +In order to encode the entry into a flat file, use the bencode() function.

      The function returning an entry may be useful to add custom entries │ │ │ │ +to the torrent file before bencoding it and saving it to disk.

      │ │ │ │ +

      Whether the resulting torrent object is v1, v2 or hybrid depends on │ │ │ │ +whether any of the v1_only or v2_only flags were set on the │ │ │ │ +constructor.

      This sets the SHA-1 hash for the specified piece (index). You are required │ │ │ │ +to set the hash for every piece in the torrent before generating it. If you have │ │ │ │ +the files on disk, you can use the high level convenience function to do this. │ │ │ │ +See set_piece_hashes(). │ │ │ │ +A SHA-1 hash of all zeros is internally used to indicate a hash that │ │ │ │ +has not been set.

      sets the bittorrent v2 hash for file file of the piece piece. │ │ │ │ +piece is relative to the first piece of the file, starting at 0. The │ │ │ │ +first piece in the file can be computed with │ │ │ │ +file_storage::file_index_at_piece(). │ │ │ │ +The hash, h, is the root of the merkle tree formed by the piece's │ │ │ │ +16 kiB blocks. Note that piece sizes must be powers-of-2, so all │ │ │ │ +per-piece merkle trees are complete. │ │ │ │ +A SHA-256 hash of all zeros is internally used to indicate a hash │ │ │ │ +that has not been set. Setting such hash will not be considered set │ │ │ │ +when calling generate(). │ │ │ │ +This function will throw std::system_error if it is called on an │ │ │ │ +object constructed with the v1_only flag.

      │ │ │ │ +

      This adds a url seed to the torrent. You can have any number of url seeds. For a │ │ │ │ +single file torrent, this should be an HTTP url, pointing to a file with identical │ │ │ │ +content as the file of the torrent. For a multi-file torrent, it should point to │ │ │ │ +a directory containing a directory with the same name as this torrent, and all the │ │ │ │ +files of the torrent in it.

      Adds a tracker to the torrent. This is not strictly required, but most torrents │ │ │ │ +use a tracker as their main source of peers. The url should be an http:// or udp:// │ │ │ │ +url to a machine running a bittorrent tracker that accepts announces for this torrent's │ │ │ │ +info-hash. The tier is the fallback priority of the tracker. All trackers with tier 0 are │ │ │ │ +tried first (in any order). If all fail, trackers with tier 1 are tried.

      This function sets an X.509 certificate in PEM format to the torrent. This makes the │ │ │ │ +torrent an SSL torrent. An SSL torrent requires that each peer has a valid certificate │ │ │ │ +signed by this root certificate. For SSL torrents, all peers are connecting over SSL │ │ │ │ +connections. For more information, see the section on ssl torrents.

      The constructor that takes an info-hash will initialize the info-hash │ │ │ │ +to the given value, but leave all other fields empty. This is used │ │ │ │ +internally when downloading torrents without the metadata. The │ │ │ │ +metadata will be created by libtorrent as soon as it has been │ │ │ │ +downloaded from the swarm.

      │ │ │ │ +

      The constructor that takes a bdecode_node will create a torrent_info │ │ │ │ +object from the information found in the given torrent_file. The │ │ │ │ +bdecode_node represents a tree node in an bencoded file. To load an │ │ │ │ +ordinary .torrent file into a bdecode_node, use bdecode().

      │ │ │ │ +

      The version that takes a buffer pointer and a size will decode it as a │ │ │ │ +.torrent file and initialize the torrent_info object for you.

      │ │ │ │ +

      The version that takes a filename will simply load the torrent file │ │ │ │ +and decode it inside the constructor, for convenience. This might not │ │ │ │ +be the most suitable for applications that want to be able to report │ │ │ │ +detailed errors on what might go wrong.

      │ │ │ │ +

      There is an upper limit on the size of the torrent file that will be │ │ │ │ +loaded by the overload taking a filename. If it's important that even │ │ │ │ +very large torrent files are loaded, use one of the other overloads.

      │ │ │ │ +

      The overloads that takes an error_code const& never throws if an │ │ │ │ +error occur, they will simply set the error code to describe what went │ │ │ │ +wrong and not fully initialize the torrent_info object. The overloads │ │ │ │ +that do not take the extra error_code parameter will always throw if │ │ │ │ +an error occurs. These overloads are not available when building │ │ │ │ +without exception support.

      │ │ │ │ +

      The overload that takes a span also needs an extra parameter of │ │ │ │ +type from_span_t to disambiguate the std::string overload for │ │ │ │ +string literals. There is an object in the libtorrent namespace of this │ │ │ │ +type called from_span.

      │ │ │ │ +

      The file_storage object contains the information on how to map the │ │ │ │ +pieces to files. It is separated from the torrent_info object because │ │ │ │ +when creating torrents a storage object needs to be created without │ │ │ │ +having a torrent file. When renaming files in a storage, the storage │ │ │ │ +needs to make its own copy of the file_storage in order to make its │ │ │ │ +mapping differ from the one in the torrent file.

      │ │ │ │ +

      orig_files() returns the original (unmodified) file storage for │ │ │ │ +this torrent. This is used by the web server connection, which needs │ │ │ │ +to request files with the original names. Filename may be changed using │ │ │ │ +torrent_info::rename_file().

      Renames the file with the specified index to the new name. The new │ │ │ │ +filename is reflected by the file_storage returned by files() │ │ │ │ +but not by the one returned by orig_files().

      │ │ │ │ +

      If you want to rename the base name of the torrent (for a multi file │ │ │ │ +torrent), you can copy the file_storage (see files() and │ │ │ │ +orig_files() ), change the name, and then use remap_files().

      │ │ │ │ +

      The new_filename can both be a relative path, in which case the │ │ │ │ +file name is relative to the save_path of the torrent. If the │ │ │ │ +new_filename is an absolute path (i.e. is_complete(new_filename) │ │ │ │ +== true), then the file is detached from the save_path of the │ │ │ │ +torrent. In this case the file is not moved when move_storage() is │ │ │ │ +invoked.

      Warning

      │ │ │ │ +

      Using remap_files() is discouraged as it's incompatible with v2 │ │ │ │ +torrents. This is because the piece boundaries and piece hashes in │ │ │ │ +v2 torrents are intimately tied to the file boundaries. Instead, │ │ │ │ +just rename individual files, or implement a custom disk_interface │ │ │ │ +to customize how to store files.

      │ │ │ │ +
      │ │ │ │ +

      Remaps the file storage to a new file layout. This can be used to, for │ │ │ │ +instance, download all data in a torrent to a single file, or to a │ │ │ │ +number of fixed size sector aligned files, regardless of the number │ │ │ │ +and sizes of the files in the torrent.

      │ │ │ │ +

      The new specified file_storage must have the exact same size as │ │ │ │ +the current one.

      torrent_handle

      │ │ │ │ +

      Declared in "libtorrent/torrent_handle.hpp"

      │ │ │ │ +

      You will usually have to store your torrent handles somewhere, since it's │ │ │ │ +the object through which you retrieve information about the torrent and │ │ │ │ +aborts the torrent.

      │ │ │ │ +
      │ │ │ │ +

      Warning

      │ │ │ │ +

      Any member function that returns a value or fills in a value has to be │ │ │ │ +made synchronously. This means it has to wait for the main thread to │ │ │ │ +complete the query before it can return. This might potentially be │ │ │ │ +expensive if done from within a GUI thread that needs to stay │ │ │ │ +responsive. Try to avoid querying for information you don't need, and │ │ │ │ +try to do it in as few calls as possible. You can get most of the │ │ │ │ +interesting information about a torrent from the │ │ │ │ +torrent_handle::status() call.

      │ │ │ │ +
      │ │ │ │ +

      The default constructor will initialize the handle to an invalid state. │ │ │ │ +Which means you cannot perform any operation on it, unless you first │ │ │ │ +assign it a valid handle. If you try to perform any operation on an │ │ │ │ +uninitialized handle, it will throw invalid_handle.

      │ │ │ │ +
      │ │ │ │ +

      Warning

      │ │ │ │ +

      All operations on a torrent_handle may throw system_error │ │ │ │ +exception, in case the handle is no longer referring to a torrent. │ │ │ │ +There is one exception is_valid() will never throw. Since the torrents │ │ │ │ +are processed by a background thread, there is no guarantee that a │ │ │ │ +handle will remain valid between two calls.

      This function will write data to the storage as piece piece, │ │ │ │ +as if it had been downloaded from a peer.

      │ │ │ │ +

      By default, data that's already been downloaded is not overwritten by │ │ │ │ +this buffer. If you trust this data to be correct (and pass the piece │ │ │ │ +hash check) you may pass the overwrite_existing flag. This will │ │ │ │ +instruct libtorrent to overwrite any data that may already have been │ │ │ │ +downloaded with this data.

      │ │ │ │ +

      Since the data is written asynchronously, you may know that is passed │ │ │ │ +or failed the hash check by waiting for piece_finished_alert or │ │ │ │ +hash_failed_alert.

      │ │ │ │ +

      Adding pieces while the torrent is being checked (i.e. in │ │ │ │ +torrent_status::checking_files state) is not supported.

      │ │ │ │ +

      The overload taking a raw pointer to the data is a blocking call. It │ │ │ │ +won't return until the libtorrent thread has copied the data into its │ │ │ │ +disk write buffer. data is expected to point to a buffer of as │ │ │ │ +many bytes as the size of the specified piece. See │ │ │ │ +file_storage::piece_size().

      │ │ │ │ +

      The data in the buffer is copied and passed on to the disk IO thread │ │ │ │ +to be written at a later point.

      │ │ │ │ +

      The overload taking a std::vector<char> is not blocking, it will │ │ │ │ +send the buffer to the main thread and return immediately.

      This function starts an asynchronous read operation of the specified │ │ │ │ +piece from this torrent. You must have completed the download of the │ │ │ │ +specified piece before calling this function.

      │ │ │ │ +

      When the read operation is completed, it is passed back through an │ │ │ │ +alert, read_piece_alert. Since this alert is a response to an explicit │ │ │ │ +call, it will always be posted, regardless of the alert mask.

      │ │ │ │ +

      Query information about connected peers for this torrent. If the │ │ │ │ +torrent_handle is invalid, it will throw a system_error exception.

      │ │ │ │ +

      post_peer_info() is asynchronous and will trigger the posting of │ │ │ │ +a peer_info_alert. The alert contain a list of peer_info objects, one │ │ │ │ +for each connected peer.

      │ │ │ │ +

      get_peer_info() is synchronous and takes a reference to a vector │ │ │ │ +that will be cleared and filled with one entry for each peer │ │ │ │ +connected to this torrent, given the handle is valid. Each entry in │ │ │ │ +the vector contains information about that particular peer. See │ │ │ │ +peer_info.

      │ │ │ │ +

      status() will return a structure with information about the status │ │ │ │ +of this torrent. If the torrent_handle is invalid, it will throw │ │ │ │ +system_error exception. See torrent_status. The flags │ │ │ │ +argument filters what information is returned in the torrent_status. │ │ │ │ +Some information in there is relatively expensive to calculate, and if │ │ │ │ +you're not interested in it (and see performance issues), you can │ │ │ │ +filter them out.

      │ │ │ │ +

      The status() function will block until the internal libtorrent │ │ │ │ +thread responds with the torrent_status object. To avoid blocking, │ │ │ │ +instead call post_status(). It will trigger posting of a │ │ │ │ +state_update_alert with a single torrent_status object for this │ │ │ │ +torrent.

      │ │ │ │ +

      In order to get regular updates for torrents whose status changes, │ │ │ │ +consider calling session::post_torrent_updates()`` instead.

│ │ │ │ +
      │ │ │ │ +

      This function sets or resets the deadline associated with a specific │ │ │ │ +piece index (index). libtorrent will attempt to download this │ │ │ │ +entire piece before the deadline expires. This is not necessarily │ │ │ │ +possible, but pieces with a more recent deadline will always be │ │ │ │ +prioritized over pieces with a deadline further ahead in time. The │ │ │ │ +deadline (and flags) of a piece can be changed by calling this │ │ │ │ +function again.

      │ │ │ │ +

      If the piece is already downloaded when this call is made, nothing │ │ │ │ +happens, unless the alert_when_available flag is set, in which case it │ │ │ │ +will have the same effect as calling read_piece() for index.

      │ │ │ │ +

      deadline is the number of milliseconds until this piece should be │ │ │ │ +completed.

      │ │ │ │ +

      reset_piece_deadline removes the deadline from the piece. If it │ │ │ │ +hasn't already been downloaded, it will no longer be considered a │ │ │ │ +priority.

      │ │ │ │ +

      clear_piece_deadlines() removes deadlines on all pieces in │ │ │ │ +the torrent. As if reset_piece_deadline() was called on all pieces.

      This function fills in the supplied vector, or returns a vector, with │ │ │ │ +the number of bytes downloaded of each file in this torrent. The │ │ │ │ +progress values are ordered the same as the files in the │ │ │ │ +torrent_info.

      │ │ │ │ +

      This operation is not very cheap. Its complexity is O(n + mj). │ │ │ │ +Where n is the number of files, m is the number of currently │ │ │ │ +downloading pieces and j is the number of blocks in a piece.

      │ │ │ │ +

      The flags parameter can be used to specify the granularity of the │ │ │ │ +file progress. If left at the default value of 0, the progress will be │ │ │ │ +as accurate as possible, but also more expensive to calculate. If │ │ │ │ +torrent_handle::piece_granularity is specified, the progress will │ │ │ │ +be specified in piece granularity. i.e. only pieces that have been │ │ │ │ +fully downloaded and passed the hash check count. When specifying │ │ │ │ +piece granularity, the operation is a lot cheaper, since libtorrent │ │ │ │ +already keeps track of this internally and no calculation is required.

The │ │ │ │ +announce entry contains both a string url which specify the │ │ │ │ +announce url for the tracker as well as an int tier, which is │ │ │ │ +specifies the order in which this tracker is tried. If you want │ │ │ │ +libtorrent to use another list of trackers for this torrent, you can │ │ │ │ +use replace_trackers() which takes a list of the same form as the │ │ │ │ +one returned from trackers() and will replace it. If you want an │ │ │ │ +immediate effect, you have to call force_reannounce(). See │ │ │ │ +announce_entry.

      │ │ │ │ +

      post_trackers() is the asynchronous version of trackers(). It │ │ │ │ +will trigger a tracker_list_alert to be posted.

      add_tracker() will look if the specified tracker is already in the │ │ │ │ +set. If it is, it doesn't do anything. If it's not in the current set │ │ │ │ +of trackers, it will insert it in the tier specified in the │ │ │ │ +announce_entry.

      save_resume_data()

      │ │ │ │ +
      │ │ │ │ +void save_resume_data (resume_data_flags_t flags = {}) const;
│ │ │ │ +
      │ │ │ │ +

      save_resume_data() asks libtorrent to generate fast-resume data for │ │ │ │ +this torrent. The fast resume data (stored in an add_torrent_params │ │ │ │ +object) can be used to resume a torrent in the next session without │ │ │ │ +having to check all files for which pieces have been downloaded. It │ │ │ │ +can also be used to save a .torrent file for a torrent_handle.

      │ │ │ │ +

      This operation is asynchronous, save_resume_data will return │ │ │ │ +immediately. The resume data is delivered when it's done through a │ │ │ │ +save_resume_data_alert.

      │ │ │ │ +

      The operation will fail, and post a save_resume_data_failed_alert │ │ │ │ +instead, in the following cases:

      │ │ │ │ +
      │ │ │ │ +
        │ │ │ │ +
      1. The torrent is in the process of being removed.
        2. │ │ │ │ +
      2. No torrent state has changed since the last saving of resume │ │ │ │ +data, and the only_if_modified flag is set. │ │ │ │ +metadata (see libtorrent's metadata from peers extension)
        3. │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +

      Note that some counters may be outdated by the time you receive the fast resume data

      │ │ │ │ +

      When saving resume data because of shutting down, make sure not to │ │ │ │ +remove_torrent() before you receive the save_resume_data_alert. │ │ │ │ +There's no need to pause the session or torrent when saving resume │ │ │ │ +data.

      │ │ │ │ +

      The paused state of a torrent is saved in the resume data, so pausing │ │ │ │ +all torrents before saving resume data will all torrents be restored │ │ │ │ +in a paused state.

      │ │ │ │ +
      │ │ │ │ +

      Note

      │ │ │ │ +

      It is typically a good idea to save resume data whenever a torrent │ │ │ │ +is completed or paused. If you save resume data for torrents when they are │ │ │ │ +paused, you can accelerate the shutdown process by not saving resume │ │ │ │ +data again for those torrents. Completed torrents should have their │ │ │ │ +resume data saved when they complete and on exit, since their │ │ │ │ +statistics might be updated.

      │ │ │ │ +
      │ │ │ │ +

      Example code to pause and save resume data for all torrents and wait │ │ │ │ +for the alerts:

      │ │ │ │ +
      │ │ │ │ +extern int outstanding_resume_data; // global counter of outstanding resume data
│ │ │ │ +std::vector<torrent_handle> handles = ses.get_torrents();

│ │ │ │ +catch (lt::system_error const& e)
│ │ │ │ +{
│ │ │ │ +        // the handle was invalid, ignore this one and move to the next
│ │ │ │ +}
│ │ │ │ +
│ │ │ │ +while (outstanding_resume_data > 0)
│ │ │ │ +{
│ │ │ │ +        alert const* a = ses.wait_for_alert(seconds(30));
│ │ │ │ +
│ │ │ │ +        // if we don't get an alert within 30 seconds, abort

      Note

      │ │ │ │ +

      Note how outstanding_resume_data is a global counter in this │ │ │ │ +example. This is deliberate, otherwise there is a race condition for │ │ │ │ +torrents that was just asked to save their resume data, they posted │ │ │ │ +the alert, but it has not been received yet. Those torrents would │ │ │ │ +report that they don't need to save resume data again, and skipped by │ │ │ │ +the initial loop, and thwart the counter otherwise.

      This function returns true if anything that is stored in the resume │ │ │ │ +data has changed since the last time resume data was saved. │ │ │ │ +The overload that takes flags let you ask if specific categories │ │ │ │ +of properties have changed. These flags have the same behavior as in │ │ │ │ +the save_resume_data() call.

      │ │ │ │ +

      This is a blocking call. It will wait for a response from │ │ │ │ +libtorrent's main thread. A way to avoid blocking is to instead │ │ │ │ +call save_resume_data() directly, specifying the conditions under │ │ │ │ +which resume data should be saved.

      │ │ │ │ +

      Note

      │ │ │ │ +

      A torrent's resume data is considered saved as soon as the │ │ │ │ +save_resume_data_alert is posted. It is important to make sure this │ │ │ │ +alert is received and handled in order for this function to be │ │ │ │ +meaningful.

      Every torrent that is added is assigned a queue position exactly one │ │ │ │ +greater than the greatest queue position of all existing torrents. │ │ │ │ +Torrents that are being seeded have -1 as their queue position, since │ │ │ │ +they're no longer in line to be downloaded.

      │ │ │ │ +

      When a torrent is removed or turns into a seed, all torrents with │ │ │ │ +greater queue positions have their positions decreased to fill in the │ │ │ │ +space in the sequence.

      │ │ │ │ +

      queue_position() returns the torrent's position in the download │ │ │ │ +queue. The torrents with the smallest numbers are the ones that are │ │ │ │ +being downloaded. The smaller number, the closer the torrent is to the │ │ │ │ +front of the line to be started.

      │ │ │ │ +

      The queue position is also available in the torrent_status.

      For SSL torrents, use this to specify a path to a .pem file to use as │ │ │ │ +this client's certificate. The certificate must be signed by the │ │ │ │ +certificate in the .torrent file to be valid.

      │ │ │ │ +

      The set_ssl_certificate_buffer() overload takes the actual certificate, │ │ │ │ +private key and DH params as strings, rather than paths to files.

      │ │ │ │ +

      cert is a path to the (signed) certificate in .pem format │ │ │ │ +corresponding to this torrent.

      │ │ │ │ +

      private_key is a path to the private key for the specified │ │ │ │ +certificate. This must be in .pem format.

      │ │ │ │ +

      dh_params is a path to the Diffie-Hellman parameter file, which │ │ │ │ +needs to be in .pem format. You can generate this file using the │ │ │ │ +openssl command like this: openssl dhparam -outform PEM -out │ │ │ │ +dhparams.pem 512.

      │ │ │ │ +

      passphrase may be specified if the private key is encrypted and │ │ │ │ +requires a passphrase to be decrypted.

      │ │ │ │ +

      Note that when a torrent first starts up, and it needs a certificate, │ │ │ │ +it will suspend connecting to any peers until it has one. It's │ │ │ │ +typically desirable to resume the torrent after setting the SSL │ │ │ │ +certificate.

      torrent_file() returns a pointer to the torrent_info object │ │ │ │ +associated with this torrent. The torrent_info object may be a copy │ │ │ │ +of the internal object. If the torrent doesn't have metadata, the │ │ │ │ +pointer will not be initialized (i.e. a nullptr). The torrent may be │ │ │ │ +in a state without metadata only if it was started without a .torrent │ │ │ │ +file, e.g. by being added by magnet link.

      │ │ │ │ +

      Note that the torrent_info object returned here may be a different │ │ │ │ +instance than the one added to the session, with different attributes │ │ │ │ +like piece layers, dht nodes and trackers. A torrent_info object does │ │ │ │ +not round-trip cleanly when added to a session.

      │ │ │ │ +

      If you want to save a .torrent file from the torrent_handle, instead │ │ │ │ +call save_resume_data() and write_torrent_file() the │ │ │ │ +add_torrent_params object passed back in the alert.

      │ │ │ │ +

      torrent_file_with_hashes() returns a copy of the internal │ │ │ │ +torrent_info and piece layer hashes (if it's a v2 torrent). The piece │ │ │ │ +layers will only be included if they are available. If this torrent │ │ │ │ +was added from a .torrent file with piece layers or if it's seeding, │ │ │ │ +the piece layers are available. This function is more expensive than │ │ │ │ +torrent_file() since it needs to make copies of this information.

      │ │ │ │ +

      The torrent_file_with_hashes() is here for backwards compatibility │ │ │ │ +when constructing a create_torrent object from a torrent_info that's │ │ │ │ +in a session. Prefer save_resume_data() + write_torrent_file().

      │ │ │ │ +

      Note that a torrent added from a magnet link may not have the full │ │ │ │ +merkle trees for all files, and hence not have the complete piece │ │ │ │ +layers. In that state, you cannot create a .torrent file even from │ │ │ │ +the torrent_info returned from torrent_file_with_hashes().

      These functions are used to set and get the priority of individual │ │ │ │ +pieces. By default all pieces have priority 4. That means that the │ │ │ │ +random rarest first algorithm is effectively active for all pieces. │ │ │ │ +You may however change the priority of individual pieces. There are 8 │ │ │ │ +priority levels. 0 means not to download the piece at all. Otherwise, │ │ │ │ +lower priority values means less likely to be picked. Piece priority │ │ │ │ +takes precedence over piece availability. Every piece with priority 7 │ │ │ │ +will be attempted to be picked before a priority 6 piece and so on.

      │ │ │ │ +

      The default priority of pieces is 4.

      │ │ │ │ +

      Piece priorities can not be changed for torrents that have not │ │ │ │ +downloaded the metadata yet. Magnet links won't have metadata │ │ │ │ +immediately. see the metadata_received_alert.

      │ │ │ │ +

      piece_priority sets or gets the priority for an individual piece, │ │ │ │ +specified by index.

      │ │ │ │ +

      prioritize_pieces takes a vector of integers, one integer per │ │ │ │ +piece in the torrent. All the piece priorities will be updated with │ │ │ │ +the priorities in the vector. │ │ │ │ +The second overload of prioritize_pieces that takes a vector of pairs │ │ │ │ +will update the priorities of only select pieces, and leave all other │ │ │ │ +unaffected. Each pair is (piece, priority). That is, the first item is │ │ │ │ +the piece index and the second item is the priority of that piece. │ │ │ │ +Invalid entries, where the piece index or priority is out of range, are │ │ │ │ +not allowed.

      │ │ │ │ +

      get_piece_priorities returns a vector with one element for each piece │ │ │ │ +in the torrent. Each element is the current priority of that piece.

      prioritize_files() takes a vector that has at as many elements as │ │ │ │ +there are files in the torrent. Each entry is the priority of that │ │ │ │ +file. The function sets the priorities of all the pieces in the │ │ │ │ +torrent based on the vector.

      │ │ │ │ +

      get_file_priorities() returns a vector with the priorities of all │ │ │ │ +files.

      │ │ │ │ +

      The priority values are the same as for piece_priority(). See │ │ │ │ +download_priority_t.

      │ │ │ │ +

      Whenever a file priority is changed, all other piece priorities are │ │ │ │ +reset to match the file priorities. In order to maintain special │ │ │ │ +priorities for particular pieces, piece_priority() has to be called │ │ │ │ +again for those pieces.

      │ │ │ │ +

      You cannot set the file priorities on a torrent that does not yet have │ │ │ │ +metadata or a torrent that is a seed. file_priority(int, int) and │ │ │ │ +prioritize_files() are both no-ops for such torrents.

      │ │ │ │ +

      Since changing file priorities may involve disk operations (of moving │ │ │ │ +files in- and out of the part file), the internal accounting of file │ │ │ │ +priorities happen asynchronously. i.e. setting file priorities and then │ │ │ │ +immediately querying them may not yield the same priorities just set. │ │ │ │ +To synchronize with the priorities taking effect, wait for the │ │ │ │ +file_prio_alert.

      │ │ │ │ +

      When combining file- and piece priorities, the resume file will record │ │ │ │ +both. When loading the resume data, the file priorities will be applied │ │ │ │ +first, then the piece priorities.

      │ │ │ │ +

      Moving data from a file into the part file is currently not │ │ │ │ +supported. If a file has its priority set to 0 after it has already │ │ │ │ +been created, it will not be moved into the partfile.

      move_storage()

│ │ │ │ +      , move_flags_t flags = move_flags_t::always_replace_files
│ │ │ │ +      ) const;
│ │ │ │ +
      │ │ │ │ +

      Moves the file(s) that this torrent are currently seeding from or │ │ │ │ +downloading to. If the given save_path is not located on the same │ │ │ │ +drive as the original save path, the files will be copied to the new │ │ │ │ +drive and removed from their original location. This will block all │ │ │ │ +other disk IO, and other torrents download and upload rates may drop │ │ │ │ +while copying the file.

      │ │ │ │ +

      Since disk IO is performed in a separate thread, this operation is │ │ │ │ +also asynchronous. Once the operation completes, the │ │ │ │ +storage_moved_alert is generated, with the new path as the │ │ │ │ +message. If the move fails for some reason, │ │ │ │ +storage_moved_failed_alert is generated instead, containing the │ │ │ │ +error message.

      │ │ │ │ +

      The flags argument determines the behavior of the copying/moving │ │ │ │ +of the files in the torrent. see move_flags_t.

      │ │ │ │ +

      always_replace_files is the default and replaces any file that │ │ │ │ +exist in both the source directory and the target directory.

      │ │ │ │ +

      fail_if_exist first check to see that none of the copy operations │ │ │ │ +would cause an overwrite. If it would, it will fail. Otherwise it will │ │ │ │ +proceed as if it was in always_replace_files mode. Note that there │ │ │ │ +is an inherent race condition here. If the files in the target │ │ │ │ +directory appear after the check but before the copy or move │ │ │ │ +completes, they will be overwritten. When failing because of files │ │ │ │ +already existing in the target path, the error of │ │ │ │ +move_storage_failed_alert is set to │ │ │ │ +boost::system::errc::file_exists.

      │ │ │ │ +

      The intention is that a client may use this as a probe, and if it │ │ │ │ +fails, ask the user which mode to use. The client may then re-issue │ │ │ │ +the move_storage call with one of the other modes.

      │ │ │ │ +

      dont_replace always keeps the existing file in the target │ │ │ │ +directory, if there is one. The source files will still be removed in │ │ │ │ +that case. Note that it won't automatically re-check files. If an │ │ │ │ +incomplete torrent is moved into a directory with the complete files, │ │ │ │ +pause, move, force-recheck and resume. Without the re-checking, the │ │ │ │ +torrent will keep downloading and files in the new download directory │ │ │ │ +will be overwritten.

      │ │ │ │ +

      Files that have been renamed to have absolute paths are not moved by │ │ │ │ +this function. Keep in mind that files that don't belong to the │ │ │ │ +torrent but are stored in the torrent's directory may be moved as │ │ │ │ +well. This goes for files that have been renamed to absolute paths │ │ │ │ +that still end up inside the save path.

      │ │ │ │ +

      When copying files, sparse regions are not likely to be preserved. │ │ │ │ +This makes it proportionally more expensive to move a large torrent │ │ │ │ +when only few pieces have been downloaded, since the files are then │ │ │ │ +allocated with zeros in the destination directory.

      Warning

      │ │ │ │ +

      The session object does not cleanly terminate with an external │ │ │ │ +io_context. The io_context::run() call must have returned │ │ │ │ +before it's safe to destruct the session. Which means you MUST │ │ │ │ +call session::abort() and save the session_proxy first, then │ │ │ │ +destruct the session object, then sync with the io_context, then │ │ │ │ +destruct the session_proxy object.

      │ │ │ │ +
      │ │ │ │ +~session ();
│ │ │ │ +
      │ │ │ │ +

      The destructor of session will notify all trackers that our torrents │ │ │ │ +have been shut down. If some trackers are down, they will time out. │ │ │ │ +All this before the destructor of session returns. So, it's advised │ │ │ │ +that any kind of interface (such as windows) are closed before │ │ │ │ +destructing the session object. Because it can take a few second for │ │ │ │ +it to finish. The timeout can be set with apply_settings().

      │ │ │ │ +

      In case you want to destruct the session asynchronously, you can │ │ │ │ +request a session destruction proxy. If you don't do this, the │ │ │ │ +destructor of the session object will block while the trackers are │ │ │ │ +contacted. If you keep one session_proxy to the session when │ │ │ │ +destructing it, the destructor will not block, but start to close down │ │ │ │ +the session, the destructor of the proxy will then synchronize the │ │ │ │ +threads. So, the destruction of the session is performed from the │ │ │ │ +session destructor call until the session_proxy destructor │ │ │ │ +call. The session_proxy does not have any operations on it (since │ │ │ │ +the session is being closed down, no operations are allowed on it). │ │ │ │ +The only valid operation is calling the destructor:

      Note

      │ │ │ │ +

      these calls are potentially expensive and won't scale well with │ │ │ │ +lots of torrents. If you're concerned about performance, consider │ │ │ │ +using post_torrent_updates() instead.

      │ │ │ │ +
      │ │ │ │ +

      get_torrent_status returns a vector of the torrent_status for │ │ │ │ +every torrent which satisfies pred, which is a predicate function │ │ │ │ +which determines if a torrent should be included in the returned set │ │ │ │ +or not. Returning true means it should be included and false means │ │ │ │ +excluded. The flags argument is the same as to │ │ │ │ +torrent_handle::status(). Since pred is guaranteed to be │ │ │ │ +called for every torrent, it may be used to count the number of │ │ │ │ +torrents of different categories as well.

      │ │ │ │ +

      refresh_torrent_status takes a vector of torrent_status structs │ │ │ │ +(for instance the same vector that was returned by │ │ │ │ +get_torrent_status() ) and refreshes the status based on the │ │ │ │ +handle member. It is possible to use this function by first │ │ │ │ +setting up a vector of default constructed torrent_status objects, │ │ │ │ +only initializing the handle member, in order to request the │ │ │ │ +torrent status for multiple torrents in a single call. This can save a │ │ │ │ +significant amount of time if you have a lot of torrents.

      │ │ │ │ +

      Any torrent_status object whose handle member is not referring to │ │ │ │ +a valid torrent are ignored.

      │ │ │ │ +

      The intended use of these functions is to start off by calling │ │ │ │ +get_torrent_status() to get a list of all torrents that match your │ │ │ │ +criteria. Then call refresh_torrent_status() on that list. This │ │ │ │ +will only refresh the status for the torrents in your list, and thus │ │ │ │ +ignore all other torrents you might be running. This may save a │ │ │ │ +significant amount of time, especially if the number of torrents you're │ │ │ │ +interested in is small. In order to keep your list of interested │ │ │ │ +torrents up to date, you can either call get_torrent_status() from │ │ │ │ +time to time, to include torrents you might have become interested in │ │ │ │ +since the last time. In order to stop refreshing a certain torrent, │ │ │ │ +simply remove it from the list.

      │ │ │ │ +

      You add torrents through the add_torrent() function where you give an │ │ │ │ +object with all the parameters. The add_torrent() overloads will block │ │ │ │ +until the torrent has been added (or failed to be added) and returns │ │ │ │ +an error code and a torrent_handle. In order to add torrents more │ │ │ │ +efficiently, consider using async_add_torrent() which returns │ │ │ │ +immediately, without waiting for the torrent to add. Notification of │ │ │ │ +the torrent being added is sent as add_torrent_alert.

      │ │ │ │ +

      The save_path field in add_torrent_params must be set to a valid │ │ │ │ +path where the files for the torrent will be saved. Even when using a │ │ │ │ +custom storage, this needs to be set to something. If the save_path │ │ │ │ +is empty, the call to add_torrent() will throw a system_error │ │ │ │ +exception.

      │ │ │ │ +

      The overload that does not take an error_code throws an exception on │ │ │ │ +error and is not available when building without exception support. │ │ │ │ +The torrent_handle returned by add_torrent() can be used to retrieve │ │ │ │ +information about the torrent's progress, its peers etc. It is also │ │ │ │ +used to abort a torrent.

      If the torrent you are trying to add already exists in the session (is │ │ │ │ +either queued for checking, being checked or downloading) │ │ │ │ +add_torrent() will throw system_error which derives from │ │ │ │ +std::exception unless duplicate_is_error is set to false. In that │ │ │ │ +case, add_torrent() will return the handle to the existing torrent.

      │ │ │ │ +

      The add_torrent_params class has a flags field. It can be used to │ │ │ │ +control what state the new torrent will be added in. Common flags to │ │ │ │ +want to control are torrent_flags::paused and │ │ │ │ +torrent_flags::auto_managed. In order to add a magnet link that will │ │ │ │ +just download the metadata, but no payload, set the │ │ │ │ +torrent_flags::upload_mode flag.

      │ │ │ │ +

      Special consideration has to be taken when adding hybrid torrents │ │ │ │ +(i.e. torrents that are BitTorrent v2 torrents that are backwards │ │ │ │ +compatible with v1). For more details, see BitTorrent v2 torrents.

      Pausing the session has the same effect as pausing every torrent in │ │ │ │ +it, except that torrents will not be resumed by the auto-manage │ │ │ │ +mechanism.

The optional salt argument is a string that │ │ │ │ +is to be mixed in with the key when determining where in the DHT │ │ │ │ +the value is to be stored. The callback function is called from within │ │ │ │ +the libtorrent network thread once we've found where to store the blob, │ │ │ │ +possibly with the current value stored under the key. │ │ │ │ +The values passed to the callback functions are:

      │ │ │ │ +
      │ │ │ │ +
      entry& value
      │ │ │ │ +
      the current value stored under the key (may be empty). Also expected │ │ │ │ +to be set to the value to be stored by the function.
      │ │ │ │ +
      std::array<char,64>& signature
      │ │ │ │ +
      the signature authenticating the current value. This may be zeros │ │ │ │ +if there is currently no value stored. The function is expected to │ │ │ │ +fill in this buffer with the signature of the new value to store. │ │ │ │ +To generate the signature, you may want to use the │ │ │ │ +sign_mutable_item function.
      │ │ │ │ +
      std::int64_t& seq
      │ │ │ │ +
      current sequence number. May be zero if there is no current value. │ │ │ │ +The function is expected to set this to the new sequence number of │ │ │ │ +the value that is to be stored. Sequence numbers must be monotonically │ │ │ │ +increasing. Attempting to overwrite a value with a lower or equal │ │ │ │ +sequence number will fail, even if the signature is correct.

Pass any data required for this function along │ │ │ │ +with the function object's context and make the function entirely │ │ │ │ +self-contained. The only reason data blob's value is computed │ │ │ │ +via a function instead of just passing in the new value is to avoid │ │ │ │ +race conditions. If you want to update the value in the DHT, you │ │ │ │ +must first retrieve it, then modify it, then write it back. The way │ │ │ │ +the DHT works, it is natural to always do a lookup before storing and │ │ │ │ +calling the callback in between is convenient.

      │ │ │ │ +

      The ip-filter essentially maps an IP -> uint32. Each bit in that 32 │ │ │ │ +bit integer represents a peer class. The least significant bit │ │ │ │ +represents class 0, the next bit class 1 and so on.

      │ │ │ │ +

      For more info, see ip_filter.

      │ │ │ │ +

      For example, to make all peers in the range 200.1.1.0 - 200.1.255.255 │ │ │ │ +belong to their own peer class, apply the following filter:

      │ │ │ │ +
      │ │ │ │ +ip_filter f = ses.get_peer_class_filter();

│ │ │ │ +ses.set_peer_class_filter(f);
│ │ │ │ +
      │ │ │ │ +

      This setting only applies to new connections, it won't affect existing │ │ │ │ +peer connections.

      │ │ │ │ +

      This function is limited to only peer class 0-31, since there are only │ │ │ │ +32 bits in the IP range mapping. Only the set bits matter; no peer │ │ │ │ +class will be removed from a peer as a result of this call, peer │ │ │ │ +classes are only added.

      │ │ │ │ +

      The peer_class argument cannot be greater than 31. The bitmasks │ │ │ │ +representing peer classes in the peer_class_filter are 32 bits.

Until this happens, │ │ │ │ +torrent_handle::is_valid() will return true, and other calls such │ │ │ │ +as torrent_handle::status() will succeed. Because of this, and because │ │ │ │ +remove_torrent() is non-blocking, the following sequence usually │ │ │ │ +succeeds (does not throw system_error): │ │ │ │ +.. code:: c++

      │ │ │ │ +

      Note that when a queued or downloading torrent is removed, its position │ │ │ │ +in the download queue is vacated and every subsequent torrent in the │ │ │ │ +queue has their queue positions updated. This can potentially cause a │ │ │ │ +large state_update to be posted. When removing all torrents, it is │ │ │ │ +advised to remove them from the back of the queue, to minimize the │ │ │ │ +shifting.

      set_alert_notify() wait_for_alert() pop_alerts()

      │ │ │ │ +
      │ │ │ │ +void pop_alerts (std::vector<alert*>* alerts);
│ │ │ │ +void set_alert_notify (std::function<void()> const& fun);
│ │ │ │ +alert* wait_for_alert (time_duration max_wait);
│ │ │ │ +
      │ │ │ │ +

      Alerts is the main mechanism for libtorrent to report errors and │ │ │ │ +events. pop_alerts fills in the vector passed to it with pointers │ │ │ │ +to new alerts. The session still owns these alerts and they will stay │ │ │ │ +valid until the next time pop_alerts is called. You may not delete │ │ │ │ +the alert objects.

      │ │ │ │ +

      It is safe to call pop_alerts from multiple different threads, as │ │ │ │ +long as the alerts themselves are not accessed once another thread │ │ │ │ +calls pop_alerts. Doing this requires manual synchronization │ │ │ │ +between the popping threads.

      │ │ │ │ +

      wait_for_alert will block the current thread for max_wait time │ │ │ │ +duration, or until another alert is posted. If an alert is available │ │ │ │ +at the time of the call, it returns immediately. The returned alert │ │ │ │ +pointer is the head of the alert queue. wait_for_alert does not │ │ │ │ +pop alerts from the queue, it merely peeks at it. The returned alert │ │ │ │ +will stay valid until pop_alerts is called twice. The first time │ │ │ │ +will pop it and the second will free it.

      │ │ │ │ +

      If there is no alert in the queue and no alert arrives within the │ │ │ │ +specified timeout, wait_for_alert returns nullptr.

      │ │ │ │ +

      In the python binding, wait_for_alert takes the number of │ │ │ │ +milliseconds to wait as an integer.

      │ │ │ │ +

      The alert queue in the session will not grow indefinitely. Make sure │ │ │ │ +to pop periodically to not miss notifications. To control the max │ │ │ │ +number of alerts that's queued by the session, see │ │ │ │ +settings_pack::alert_queue_size.

      │ │ │ │ +

      Some alerts are considered so important that they are posted even when │ │ │ │ +the alert queue is full. Some alerts are considered mandatory and cannot │ │ │ │ +be disabled by the alert_mask. For instance, │ │ │ │ +save_resume_data_alert and save_resume_data_failed_alert are always │ │ │ │ +posted, regardless of the alert mask.

      │ │ │ │ +

      To control which alerts are posted, set the alert_mask │ │ │ │ +(settings_pack::alert_mask).

      │ │ │ │ +

      If the alert queue fills up to the point where alerts are dropped, this │ │ │ │ +will be indicated by a alerts_dropped_alert, which contains a bitmask │ │ │ │ +of which types of alerts were dropped. Generally it is a good idea to │ │ │ │ +make sure the alert queue is large enough, the alert_mask doesn't have │ │ │ │ +unnecessary categories enabled and to call pop_alert() frequently, to │ │ │ │ +avoid alerts being dropped.

      │ │ │ │ +

      the set_alert_notify function lets the client set a function object │ │ │ │ +to be invoked every time the alert queue goes from having 0 alerts to │ │ │ │ +1 alert. This function is called from within libtorrent, it may be the │ │ │ │ +main thread, or it may be from within a user call. The intention of │ │ │ │ +of the function is that the client wakes up its main thread, to poll │ │ │ │ +for more alerts using pop_alerts(). If the notify function fails │ │ │ │ +to do so, it won't be called again, until pop_alerts is called for │ │ │ │ +some other reason. For instance, it could signal an eventfd, post a │ │ │ │ +message to an HWND or some other main message pump. The actual │ │ │ │ +retrieval of alerts should not be done in the callback. In fact, the │ │ │ │ +callback should not block. It should not perform any expensive work. │ │ │ │ +It really should just notify the main application thread.

      │ │ │ │ +

      The type of an alert is returned by the polymorphic function │ │ │ │ +alert::type() but can also be queries from a concrete type via │ │ │ │ +T::alert_type, as a static constant.

      │ │ │ │ -

      send_buffer_low_watermark the minimum send buffer target size │ │ │ │ -(send buffer includes bytes pending being read from disk). For good │ │ │ │ -and snappy seeding performance, set this fairly high, to at least │ │ │ │ -fit a few blocks. This is essentially the initial window size which │ │ │ │ -will determine how fast we can ramp up the send rate

      │ │ │ │ -

      if the send buffer has fewer bytes than send_buffer_watermark, │ │ │ │ -we'll read another 16 kiB block onto it. If set too small, upload │ │ │ │ -rate capacity will suffer. If set too high, memory will be wasted. │ │ │ │ -The actual watermark may be lower than this in case the upload rate │ │ │ │ -is low, this is the upper limit.

      │ │ │ │ -

      the current upload rate to a peer is multiplied by this factor to │ │ │ │ -get the send buffer watermark. The factor is specified as a │ │ │ │ -percentage. i.e. 50 -> 0.5 This product is clamped to the │ │ │ │ -send_buffer_watermark setting to not exceed the max. For high │ │ │ │ -speed upload, this should be set to a greater value than 100. For │ │ │ │ -high capacity connections, setting this higher can improve upload │ │ │ │ -performance and disk throughput. Setting it too high may waste RAM │ │ │ │ -and create a bias towards read jobs over write jobs.

      for auto managed torrents, these are the limits they are subject │ │ │ │ -to. If there are too many torrents some of the auto managed ones │ │ │ │ -will be paused until some slots free up. active_downloads and │ │ │ │ -active_seeds controls how many active seeding and downloading │ │ │ │ -torrents the queuing mechanism allows. The target number of active │ │ │ │ -torrents is min(active_downloads + active_seeds, active_limit). │ │ │ │ -active_downloads and active_seeds are upper limits on the │ │ │ │ -number of downloading torrents and seeding torrents respectively. │ │ │ │ -Setting the value to -1 means unlimited.

      │ │ │ │ -

      For example if there are 10 seeding torrents and 10 downloading │ │ │ │ -torrents, and active_downloads is 4 and active_seeds is 4, │ │ │ │ -there will be 4 seeds active and 4 downloading torrents. If the │ │ │ │ -settings are active_downloads = 2 and active_seeds = 4, │ │ │ │ -then there will be 2 downloading torrents and 4 seeding torrents │ │ │ │ -active. Torrents that are not auto managed are not counted against │ │ │ │ -these limits.

      active_checking is the limit of number of simultaneous checking │ │ │ │ -torrents.

      active_limit is a hard limit on the number of active (auto │ │ │ │ -managed) torrents. This limit also applies to slow torrents.

      active_lsd_limit is the max number of torrents to announce to │ │ │ │ -the local network over the local service discovery protocol.

      You can have more torrents active, even though they are not │ │ │ │ -announced to the DHT, lsd or their tracker. If some peer knows │ │ │ │ -about you for any reason and tries to connect, it will still be │ │ │ │ -accepted, unless the torrent is paused, which means it won't accept │ │ │ │ -any connections.

      auto_scrape_interval is the number of seconds between scrapes │ │ │ │ -of queued torrents (auto managed and paused torrents). Auto managed │ │ │ │ -torrents that are paused, are scraped regularly in order to keep │ │ │ │ -track of their downloader/seed ratio. This ratio is used to │ │ │ │ -determine which torrents to seed and which to pause.

      │ │ │ │ -

      auto_scrape_min_interval is the minimum number of seconds │ │ │ │ -between any automatic scrape (regardless of torrent). In case there │ │ │ │ -are a large number of paused auto managed torrents, this puts a │ │ │ │ -limit on how often a scrape request is sent.

      Adds a file to the file storage. The add_file_borrow version │ │ │ │ +expects that filename is the file name (without a path) of │ │ │ │ +the file that's being added. │ │ │ │ +This memory is borrowed, i.e. it is the caller's │ │ │ │ +responsibility to make sure it stays valid throughout the lifetime │ │ │ │ +of this file_storage object or any copy of it. The same thing applies │ │ │ │ +to filehash, which is an optional pointer to a 20 byte binary │ │ │ │ +SHA-1 hash of the file.

      │ │ │ │ +

      if filename is empty, the filename from path is used and not │ │ │ │ +borrowed.

      │ │ │ │ +

      The path argument is the full path (in the torrent file) to │ │ │ │ +the file to add. Note that this is not supposed to be an absolute │ │ │ │ +path, but it is expected to include the name of the torrent as the │ │ │ │ +first path element.

      │ │ │ │ +

      file_size is the size of the file in bytes.

      │ │ │ │ +

      The file_flags argument sets attributes on the file. The file │ │ │ │ +attributes is an extension and may not work in all bittorrent clients.

      │ │ │ │ +

      For possible file attributes, see file_storage::flags_t.

      │ │ │ │ +

      The mtime argument is optional and can be set to 0. If non-zero, │ │ │ │ +it is the posix time of the last modification time of this file.

      │ │ │ │ +

      symlink_path is the path the file is a symlink to. To make this a │ │ │ │ +symlink you also need to set the file_storage::flag_symlink file flag.

      │ │ │ │ +

      root_hash is an optional pointer to a 32 byte SHA-256 hash, being │ │ │ │ +the merkle tree root hash for this file. This is only used for v2 │ │ │ │ +torrents. If the root hash is specified for one file, it has to │ │ │ │ +be specified for all, otherwise this function will fail. │ │ │ │ +Note that the buffer root_hash points to must out-live the │ │ │ │ +file_storage object, it will not be copied. This parameter is only │ │ │ │ +used when loading torrents, that already have their file hashes │ │ │ │ +computed. When creating torrents, the file hashes will be computed by │ │ │ │ +the piece hashes.

      │ │ │ │ +

      If more files than one are added, certain restrictions to their paths │ │ │ │ +apply. In a multi-file file storage (torrent), all files must share │ │ │ │ +the same root directory.

      │ │ │ │ +

      That is, the first path element of all files must be the same. │ │ │ │ +This shared path element is also set to the name of the torrent. It │ │ │ │ +can be changed by calling set_name.

      │ │ │ │ +

      The overloads that take an error_code reference will report failures │ │ │ │ +via that variable, otherwise system_error is thrown.

      utp_target_delay is the target delay for uTP sockets in │ │ │ │ -milliseconds. A high value will make uTP connections more │ │ │ │ -aggressive and cause longer queues in the upload bottleneck. It │ │ │ │ -cannot be too low, since the noise in the measurements would cause │ │ │ │ -it to send too slow. │ │ │ │ -utp_gain_factor is the number of bytes the uTP congestion │ │ │ │ -window can increase at the most in one RTT. │ │ │ │ -If this is set too high, the congestion controller reacts │ │ │ │ -too hard to noise and will not be stable, if it's set too low, it │ │ │ │ -will react slow to congestion and not back off as fast.

      │ │ │ │ -

      utp_min_timeout is the shortest allowed uTP socket timeout, │ │ │ │ -specified in milliseconds. The │ │ │ │ -timeout depends on the RTT of the connection, but is never smaller │ │ │ │ -than this value. A connection times out when every packet in a │ │ │ │ -window is lost, or when a packet is lost twice in a row (i.e. the │ │ │ │ -resent packet is lost as well).

      │ │ │ │ -

      The shorter the timeout is, the faster the connection will recover │ │ │ │ -from this situation, assuming the RTT is low enough. │ │ │ │ -utp_syn_resends is the number of SYN packets that are sent (and │ │ │ │ -timed out) before giving up and closing the socket. │ │ │ │ -utp_num_resends is the number of times a packet is sent (and │ │ │ │ -lost or timed out) before giving up and closing the connection. │ │ │ │ -utp_connect_timeout is the number of milliseconds of timeout │ │ │ │ -for the initial SYN packet for uTP connections. For each timed out │ │ │ │ -packet (in a row), the timeout is doubled. utp_loss_multiplier │ │ │ │ -controls how the congestion window is changed when a packet loss is │ │ │ │ -experienced. It's specified as a percentage multiplier for │ │ │ │ -cwnd. Do not change this value unless you know what you're doing. │ │ │ │ -Never set it higher than 100.

      The mixed_mode_algorithm determines how to treat TCP │ │ │ │ -connections when there are uTP connections. Since uTP is designed │ │ │ │ -to yield to TCP, there's an inherent problem when using swarms that │ │ │ │ -have both TCP and uTP connections. If nothing is done, uTP │ │ │ │ -connections would often be starved out for bandwidth by the TCP │ │ │ │ -connections. This mode is prefer_tcp. The peer_proportional │ │ │ │ -mode simply looks at the current throughput and rate limits all TCP │ │ │ │ -connections to their proportional share based on how many of the │ │ │ │ -connections are TCP. This works best if uTP connections are not │ │ │ │ -rate limited by the global rate limiter (which they aren't by │ │ │ │ -default).

      The pop_alerts() function on session is the main interface for retrieving │ │ │ │ +alerts (warnings, messages and errors from libtorrent). If no alerts have │ │ │ │ +been posted by libtorrent pop_alerts() will return an empty list.

      │ │ │ │ +

      By default, only errors are reported. settings_pack::alert_mask can be │ │ │ │ +used to specify which kinds of events should be reported. The alert mask is │ │ │ │ +a combination of the alert_category_t flags in the alert class.

      │ │ │ │ +

      Every alert belongs to one or more category. There is a cost associated with │ │ │ │ +posting alerts. Only alerts that belong to an enabled category are │ │ │ │ +posted. Setting the alert bitmask to 0 will disable all alerts (except those │ │ │ │ +that are non-discardable). Alerts that are responses to API calls such as │ │ │ │ +save_resume_data() and post_session_stats() are non-discardable and will be │ │ │ │ +posted even if their category is disabled.

      │ │ │ │ +

      There are other alert base classes that some alerts derive from, all the │ │ │ │ +alerts that are generated for a specific torrent are derived from │ │ │ │ +torrent_alert, and tracker events derive from tracker_alert.

      │ │ │ │ +

      Alerts returned by pop_alerts() are only valid until the next call to │ │ │ │ +pop_alerts(). You may not copy an alert object to access it after the next │ │ │ │ +call to pop_alerts(). Internal members of alerts also become invalid once │ │ │ │ +pop_alerts() is called again.

      │ │ │ │ +

      The torrent_removed_alert is posted whenever a torrent is removed. Since │ │ │ │ +the torrent handle in its base class will usually be invalid (since the torrent │ │ │ │ +is already removed) it has the info hash as a member, to identify it. │ │ │ │ +It's posted when the alert_category::status bit is set in the alert_mask.

      │ │ │ │ +

      Note that the handle remains valid for some time after │ │ │ │ +torrent_removed_alert is posted, as long as some internal libtorrent │ │ │ │ +task (such as an I/O task) refers to it. Additionally, other alerts like │ │ │ │ +save_resume_data_alert may be posted after torrent_removed_alert. │ │ │ │ +To synchronize on whether the torrent has been removed or not, call │ │ │ │ +torrent_handle::in_session(). This will return true before │ │ │ │ +torrent_removed_alert is posted, and false afterward.

      │ │ │ │ +

      Even though the handle member doesn't point to an existing torrent anymore, │ │ │ │ +it is still useful for comparing to other handles, which may also no │ │ │ │ +longer point to existing torrents, but to the same non-existing torrents.

      │ │ │ │ +

      outstanding_disk_buffer_limit_reached0This warning means that the number of bytes queued to be written to disk │ │ │ │ +exceeds the max disk byte queue setting (settings_pack::max_queued_disk_bytes). │ │ │ │ +This might restrict the download rate, by not queuing up enough write jobs │ │ │ │ +to the disk I/O thread.

      alert_queue_size is the maximum number of alerts queued up │ │ │ │ -internally. If alerts are not popped, the queue will eventually │ │ │ │ -fill up to this level. Once the alert queue is full, additional │ │ │ │ -alerts will be dropped, and not delivered to the client. Once the │ │ │ │ -client drains the queue, new alerts may be delivered again.

      outstanding_request_limit_reached1This is posted when libtorrent would like to send more requests to a peer, │ │ │ │ +but it's limited by settings_pack::max_out_request_queue. The queue length │ │ │ │ +libtorrent is trying to achieve is determined by the download rate and the │ │ │ │ +assumed round-trip-time (settings_pack::request_queue_time). The assumed │ │ │ │ +round-trip-time is not limited to just the network RTT, but also the remote disk │ │ │ │ +access time and message handling time. It defaults to 3 seconds. The target number │ │ │ │ +of outstanding requests is set to fill the bandwidth-delay product (assumed RTT │ │ │ │ +times download rate divided by number of bytes per request). When this alert │ │ │ │ +is posted, there is a risk that the number of outstanding requests is too low │ │ │ │ +and limits the download rate. You might want to increase the max_out_request_queue │ │ │ │ +setting.

      upload_limit_too_low2This warning is posted when the amount of TCP/IP overhead is greater than the │ │ │ │ +upload rate limit. When this happens, the TCP/IP overhead is caused by a much │ │ │ │ +faster download rate, triggering TCP ACK packets. These packets eat into the │ │ │ │ +rate limit specified to libtorrent. When the overhead traffic is greater than │ │ │ │ +the rate limit, libtorrent will not be able to send any actual payload, such │ │ │ │ +as piece requests. This means the download rate will suffer, and new requests │ │ │ │ +can be sent again. There will be an equilibrium where the download rate, on │ │ │ │ +average, is about 20 times the upload rate limit. If you want to maximize the │ │ │ │ +download rate, increase the upload rate limit above 5% of your download capacity.

      We're stalled on the disk.

      1. It prevents "zero copy" disk buffers being sent to peers, since │ │ │ │ -each peer needs to mutate the data (i.e. encrypt it) the data │ │ │ │ -must be copied per peer connection rather than sending the same │ │ │ │ -buffer to multiple peers.

      2. The encryption itself requires more CPU than plain bittorrent │ │ │ │ -protocol. The highest cost is the Diffie Hellman exchange on │ │ │ │ -connection setup.
        3. │ │ │ │ -
      3. The encryption handshake adds several round-trips to the │ │ │ │ -connection setup, and delays transferring data.

      You use it by first instantiating it, then call update() to feed it │ │ │ │ +with data. i.e. you don't have to keep the entire buffer of which you want to │ │ │ │ +create the hash in memory. You can feed the hasher parts of it at a time. When │ │ │ │ +You have fed the hasher with all the data, you call final() and it │ │ │ │ +will return the sha1-hash of the data.

      │ │ │ │ +

      The constructor that takes a char const* and an integer will construct the │ │ │ │ +sha1 context and feed it the data passed in.

      │ │ │ │ +

      If you want to reuse the hasher object once you have created a hash, you have to │ │ │ │ +call reset() to reinitialize it.

      │ │ │ │ +

      The built-in software version of sha1-algorithm was implemented │ │ │ │ +by Steve Reid and released as public domain. │ │ │ │ +For more info, see src/sha1.cpp.

      info_hash_t

      │ │ │ │ +

      Declared in "libtorrent/info_hash.hpp"

      │ │ │ │ +

      class holding the info-hash of a torrent. It can hold a v1 info-hash │ │ │ │ +(SHA-1) or a v2 info-hash (SHA-256) or both.

      │ │ │ │
      │ │ │ │

      Note

      │ │ │ │ -

      This setting is only meant for very special cases where a │ │ │ │ -seed's listening port differs from the external port. As an │ │ │ │ -example, if a local proxy is used and that the proxy supports │ │ │ │ -reverse tunnels through NAT-PMP, the tracker must connect to │ │ │ │ -the external NAT-PMP port (configured using announce_port) │ │ │ │ -instead of the actual local listening port.

      │ │ │ │ +

      If has_v2() is false then the v1 hash might actually be a truncated │ │ │ │ +v2 hash

│ │ │ │ +
      │ │ │ │ +

      Generates a magnet URI from the specified torrent.

      │ │ │ │ +

      Several fields from the add_torrent_params objects are recorded in the │ │ │ │ +magnet link. In order to not include them, they have to be cleared before │ │ │ │ +calling make_magnet_uri(). These fields are used:

      │ │ │ │ +
      │ │ │ │ +ti, info_hashes, url_seeds, dht_nodes, │ │ │ │ +file_priorities, trackers, name, peers.
      │ │ │ │ +

      Depending on what the use case for the resulting magnet link is, clearing │ │ │ │ +peers and dht_nodes is probably a good idea if the add_torrent_params │ │ │ │ +came from a running torrent. Those lists may be long and be ephemeral.

      │ │ │ │ +

      If none of the info_hashes or ti fields are set, there is not │ │ │ │ +info-hash available, and a magnet link cannot be created. In this case │ │ │ │ +make_magnet_uri() returns an empty string.

      │ │ │ │ +

      The recommended way to generate a magnet link from a torrent_handle is to │ │ │ │ +call save_resume_data(), which will post a save_resume_data_alert │ │ │ │ +containing an add_torrent_params object. This can then be passed to │ │ │ │ +make_magnet_uri().

      │ │ │ │ +

      The overload that takes a torrent_handle will make blocking calls to │ │ │ │ +query information about the torrent. If the torrent handle is invalid, │ │ │ │ +an empty string is returned.

      │ │ │ │ +

      Declared in "libtorrent/torrent_flags.hpp"

      │ │ │ │ +
      │ │ │ │ +
      seed_mode
      │ │ │ │ +

      If seed_mode is set, libtorrent will assume that all files │ │ │ │ +are present for this torrent and that they all match the hashes in │ │ │ │ +the torrent file. Each time a peer requests to download a block, │ │ │ │ +the piece is verified against the hash, unless it has been verified │ │ │ │ +already. If a hash fails, the torrent will automatically leave the │ │ │ │ +seed mode and recheck all the files. The use case for this mode is │ │ │ │ +if a torrent is created and seeded, or if the user already know │ │ │ │ +that the files are complete, this is a way to avoid the initial │ │ │ │ +file checks, and significantly reduce the startup time.

      │ │ │ │ +

      Setting seed_mode on a torrent without metadata (a │ │ │ │ +.torrent file) is a no-op and will be ignored.

      │ │ │ │ +

      It is not possible to set the seed_mode flag on a torrent after it has │ │ │ │ +been added to a session. It is possible to clear it though.

      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      upload_mode
      │ │ │ │ +

      If upload_mode is set, the torrent will be initialized in │ │ │ │ +upload-mode, which means it will not make any piece requests. This │ │ │ │ +state is typically entered on disk I/O errors, and if the torrent │ │ │ │ +is also auto managed, it will be taken out of this state │ │ │ │ +periodically (see settings_pack::optimistic_disk_retry).

      │ │ │ │ +

      This mode can be used to avoid race conditions when │ │ │ │ +adjusting priorities of pieces before allowing the torrent to start │ │ │ │ +downloading.

      │ │ │ │ +

      If the torrent is auto-managed (auto_managed), the torrent │ │ │ │ +will eventually be taken out of upload-mode, regardless of how it │ │ │ │ +got there. If it's important to manually control when the torrent │ │ │ │ +leaves upload mode, don't make it auto managed.

      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      share_mode
      │ │ │ │ +

      determines if the torrent should be added in share mode or not. │ │ │ │ +Share mode indicates that we are not interested in downloading the │ │ │ │ +torrent, but merely want to improve our share ratio (i.e. increase │ │ │ │ +it). A torrent started in share mode will do its best to never │ │ │ │ +download more than it uploads to the swarm. If the swarm does not │ │ │ │ +have enough demand for upload capacity, the torrent will not │ │ │ │ +download anything. This mode is intended to be safe to add any │ │ │ │ +number of torrents to, without manual screening, without the risk │ │ │ │ +of downloading more than is uploaded.

      │ │ │ │ +

      A torrent in share mode sets the priority to all pieces to 0, │ │ │ │ +except for the pieces that are downloaded, when pieces are decided │ │ │ │ +to be downloaded. This affects the progress bar, which might be set │ │ │ │ +to "100% finished" most of the time. Do not change file or piece │ │ │ │ +priorities for torrents in share mode, it will make it not work.

      │ │ │ │ +

      The share mode has one setting, the share ratio target, see │ │ │ │ +settings_pack::share_mode_target for more info.

      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      apply_ip_filter
      │ │ │ │ +
      determines if the IP filter should apply to this torrent or not. By │ │ │ │ +default all torrents are subject to filtering by the IP filter │ │ │ │ +(i.e. this flag is set by default). This is useful if certain │ │ │ │ +torrents needs to be exempt for some reason, being an auto-update │ │ │ │ +torrent for instance.
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      paused
      │ │ │ │ +
      specifies whether or not the torrent is paused. i.e. it won't connect to the tracker or any of the peers │ │ │ │ +until it's resumed. Note that a paused torrent that also has the │ │ │ │ +auto_managed flag set can be started at any time by libtorrent's queuing │ │ │ │ +logic. See queuing.
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      auto_managed
      │ │ │ │ +

      If the torrent is auto-managed (auto_managed), the torrent │ │ │ │ +may be resumed at any point, regardless of how it paused. If it's │ │ │ │ +important to manually control when the torrent is paused and │ │ │ │ +resumed, don't make it auto managed.

      │ │ │ │ +

      If auto_managed is set, the torrent will be queued, │ │ │ │ +started and seeded automatically by libtorrent. When this is set, │ │ │ │ +the torrent should also be started as paused. The default queue │ │ │ │ +order is the order the torrents were added. They are all downloaded │ │ │ │ +in that order. For more details, see queuing.

      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      duplicate_is_error
      │ │ │ │ +
      used in add_torrent_params to indicate that it's an error to attempt │ │ │ │ +to add a torrent that's already in the session. If it's not considered an │ │ │ │ +error, a handle to the existing torrent is returned. │ │ │ │ +This flag is not saved by write_resume_data(), since it is only meant for │ │ │ │ +adding torrents.
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      update_subscribe
      │ │ │ │ +
      on by default and means that this torrent will be part of state │ │ │ │ +updates when calling post_torrent_updates(). │ │ │ │ +This flag is not saved by write_resume_data().
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      super_seeding
      │ │ │ │ +
      sets the torrent into super seeding/initial seeding mode. If the torrent │ │ │ │ +is not a seed, this flag has no effect.
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      sequential_download
      │ │ │ │ +
      sets the sequential download state for the torrent. In this mode the │ │ │ │ +piece picker will pick pieces with low index numbers before pieces with │ │ │ │ +high indices. The actual pieces that are picked depend on other factors │ │ │ │ +still, such as which pieces a peer has and whether it is in parole mode │ │ │ │ +or "prefer whole pieces"-mode. Sequential mode is not ideal for streaming │ │ │ │ +media. For that, see set_piece_deadline() instead.
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      stop_when_ready
      │ │ │ │ +

      When this flag is set, the torrent will force stop whenever it │ │ │ │ +transitions from a non-data-transferring state into a data-transferring │ │ │ │ +state (referred to as being ready to download or seed). This is useful │ │ │ │ +for torrents that should not start downloading or seeding yet, but want │ │ │ │ +to be made ready to do so. A torrent may need to have its files checked │ │ │ │ +for instance, so it needs to be started and possibly queued for checking │ │ │ │ +(auto-managed and started) but as soon as it's done, it should be │ │ │ │ +stopped.

      │ │ │ │ +

      Force stopped means auto-managed is set to false and it's paused. As │ │ │ │ +if the auto_manages flag is cleared and the paused flag is set on the torrent.

      │ │ │ │ +

      Note that the torrent may transition into a downloading state while │ │ │ │ +setting this flag, and since the logic is edge triggered you may │ │ │ │ +miss the edge. To avoid this race, if the torrent already is in a │ │ │ │ +downloading state when this call is made, it will trigger the │ │ │ │ +stop-when-ready immediately.

      │ │ │ │ +

      When the stop-when-ready logic fires, the flag is cleared. Any │ │ │ │ +subsequent transitions between downloading and non-downloading states │ │ │ │ +will not be affected, until this flag is set again.

      │ │ │ │ +

      The behavior is more robust when setting this flag as part of adding │ │ │ │ +the torrent. See add_torrent_params.

      │ │ │ │ +

      The stop-when-ready flag fixes the inherent race condition of waiting │ │ │ │ +for the state_changed_alert and then call pause(). The download/seeding │ │ │ │ +will most likely start in between posting the alert and receiving the │ │ │ │ +call to pause.

      │ │ │ │ +

      A downloading state is one where peers are being connected. Which means │ │ │ │ +just downloading the metadata via the ut_metadata extension counts │ │ │ │ +as a downloading state. In order to stop a torrent once the metadata │ │ │ │ +has been downloaded, instead set all file priorities to dont_download

      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      override_trackers
      │ │ │ │ +
      when this flag is set, the tracker list in the add_torrent_params │ │ │ │ +object override any trackers from the torrent file. If the flag is │ │ │ │ +not set, the trackers from the add_torrent_params object will be │ │ │ │ +added to the list of trackers used by the torrent. │ │ │ │ +This flag is set by read_resume_data() if there are trackers present in │ │ │ │ +the resume data file. This effectively makes the trackers saved in the │ │ │ │ +resume data take precedence over the original trackers. This includes if │ │ │ │ +there's an empty list of trackers, to support the case where they were │ │ │ │ +explicitly removed in the previous session. │ │ │ │ +This flag is not saved by write_resume_data()
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      override_web_seeds
      │ │ │ │ +
      If this flag is set, the web seeds from the add_torrent_params │ │ │ │ +object will override any web seeds in the torrent file. If it's not │ │ │ │ +set, web seeds in the add_torrent_params object will be added to the │ │ │ │ +list of web seeds used by the torrent. │ │ │ │ +This flag is set by read_resume_data() if there are web seeds present in │ │ │ │ +the resume data file. This effectively makes the web seeds saved in the │ │ │ │ +resume data take precedence over the original ones. This includes if │ │ │ │ +there's an empty list of web seeds, to support the case where they were │ │ │ │ +explicitly removed in the previous session. │ │ │ │ +This flag is not saved by write_resume_data()
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      need_save_resume
      │ │ │ │ +

      if this flag is set (which it is by default) the torrent will be │ │ │ │ +considered needing to save its resume data immediately, in the │ │ │ │ +category if_metadata_changed. See resume_data_flags_t and │ │ │ │ +save_resume_data() for details.

      │ │ │ │ +

      This flag is cleared by a successful call to save_resume_data() │ │ │ │ +This flag is not saved by write_resume_data(), since it represents an │ │ │ │ +ephemeral state of a running torrent.

      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      disable_dht
      │ │ │ │ +
      set this flag to disable DHT for this torrent. This lets you have the DHT │ │ │ │ +enabled for the whole client, and still have specific torrents not │ │ │ │ +participating in it. i.e. not announcing to the DHT nor picking up peers │ │ │ │ +from it.
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      disable_lsd
      │ │ │ │ +
      set this flag to disable local service discovery for this torrent.
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      disable_pex
      │ │ │ │ +
      set this flag to disable peer exchange for this torrent.
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      no_verify_files
      │ │ │ │ +
      if this flag is set, the resume data will be assumed to be correct │ │ │ │ +without validating it against any files on disk. This may be used when │ │ │ │ +restoring a session by loading resume data from disk. It will save time │ │ │ │ +and also delay any hard disk errors until files are actually needed. If │ │ │ │ +the resume data cannot be trusted, or if a torrent is added for the first │ │ │ │ +time to some save path that may already have some of the files, this flag │ │ │ │ +should not be set.
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      default_dont_download
      │ │ │ │ +
      default all file priorities to dont_download. This is useful for adding │ │ │ │ +magnet links where the number of files is unknown, but the │ │ │ │ +file_priorities is still set for some files. Any file not covered by │ │ │ │ +the file_priorities list will be set to normal download priority, │ │ │ │ +unless this flag is set, in which case they will be set to 0 │ │ │ │ +(dont_download).
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      i2p_torrent
      │ │ │ │ +
      this flag makes the torrent be considered an "i2p torrent" for purposes │ │ │ │ +of the allow_i2p_mixed setting. When mixing regular peers and i2p peers │ │ │ │ +is disabled, i2p torrents won't add normal peers to its peer list. │ │ │ │ +Note that non i2p torrents may still allow i2p peers (on the off-chance │ │ │ │ +that a tracker return them and the session is configured with a SAM │ │ │ │ +connection). │ │ │ │ +This flag is set automatically when adding a torrent that has at least │ │ │ │ +one tracker whose hostname ends with .i2p. │ │ │ │ +It's also set by parse_magnet_uri() if the tracker list contains such │ │ │ │ +URL.
      │ │ │ │ +
      │ │ │ │ +
      │ │ │ │ +
      all
      │ │ │ │ +

      Functions with the dict_ prefix operates on dictionaries. They are │ │ │ │ +only valid if type() == dict_t. In case a key you're looking up │ │ │ │ +contains a 0 byte, you cannot use the 0-terminated string overloads, │ │ │ │ +but have to use string_view instead. dict_find_list will return a │ │ │ │ +valid bdecode_node if the key is found _and_ it is a list. Otherwise │ │ │ │ +it will return a default-constructed bdecode_node.

      │ │ │ │ +

      Functions with the _value suffix return the value of the node │ │ │ │ +directly, rather than the nodes. In case the node is not found, or it has │ │ │ │ +a different type, a default value is returned (which can be specified).

      dict_at() returns the (key, value)-pair at the specified index in a │ │ │ │ +dictionary. Keys are only allowed to be strings. dict_at_node() also │ │ │ │ +returns the (key, value)-pair, but the key is returned as a │ │ │ │ +bdecode_node (and it will always be a string).

      │ │ │ │ +

      This function decodes/parses bdecoded data (for example a .torrent file). │ │ │ │ +The data structure is returned in the ret argument. the buffer to parse │ │ │ │ +is specified by the start of the buffer as well as the end, i.e. one │ │ │ │ +byte past the end. If the buffer fails to parse, the function returns a │ │ │ │ +non-zero value and fills in ec with the error code. The optional │ │ │ │ +argument error_pos, if set to non-nullptr, will be set to the byte offset │ │ │ │ +into the buffer where the parse failure occurred.

      │ │ │ │ +

      depth_limit specifies the max number of nested lists or dictionaries are │ │ │ │ +allowed in the data structure. (This affects the stack usage of the │ │ │ │ +function, be careful not to set it too high).

      │ │ │ │ +

      token_limit is the max number of tokens allowed to be parsed from the │ │ │ │ +buffer. This is simply a sanity check to not have unbounded memory usage.

      │ │ │ │ +

      The resulting bdecode_node is an owning node. That means it will │ │ │ │ +be holding the whole parsed tree. When iterating lists and dictionaries, │ │ │ │ +those bdecode_node objects will simply have references to the root or │ │ │ │ +owning bdecode_node. If the root node is destructed, all other nodes │ │ │ │ +that refer to anything in that tree become invalid.

      │ │ │ │ +

      However, the underlying buffer passed in to this function (start, end) │ │ │ │ +must also remain valid while the bdecoded tree is used. The parsed tree │ │ │ │ +produced by this function does not copy any data out of the buffer, but │ │ │ │ +simply produces references back into it.

      │ │ │ │ +
      the number of bytes downloaded and uploaded to all peers, accumulated, │ │ │ │ +this session only. The session is considered to restart when a │ │ │ │ +torrent is paused and restarted again.

      the number of bytes that has been downloaded and that has failed the │ │ │ │ +piece hash test. In other words, this is just how much crap that has │ │ │ │ +been downloaded since the torrent was last started. If a torrent is │ │ │ │ +paused and then restarted again, this counter will be reset.

      total_redundant_bytes
      │ │ │ │ +
      the number of bytes that has been downloaded even though that data │ │ │ │ +already was downloaded. The reason for this is that in some situations │ │ │ │ +the same data can be downloaded by mistake. When libtorrent sends │ │ │ │ +requests to a peer, and the peer doesn't send a response within a │ │ │ │ +certain timeout, libtorrent will re-request that block. Another │ │ │ │ +situation when libtorrent may re-request blocks is when the requests │ │ │ │ +it sends out are not replied in FIFO-order (it will re-request blocks │ │ │ │ +that are skipped by an out of order block). This is supposed to be as │ │ │ │ +low as possible. This only counts bytes since the torrent was last │ │ │ │ +started. If a torrent is paused and then restarted again, this counter │ │ │ │ +will be reset.

      Bencoding is a common representation in bittorrent used for dictionary, │ │ │ │ +list, int and string hierarchies. It's used to encode .torrent files and │ │ │ │ +some messages in the network protocol. libtorrent also uses it to store │ │ │ │ +settings, resume data and other session state.

      │ │ │ │ +

      Strings in bencoded structures do not necessarily represent text. │ │ │ │ +Strings are raw byte buffers of a certain length. If a string is meant to be │ │ │ │ +interpreted as text, it is required to be UTF-8 encoded. See BEP 3.

      │ │ │ │ +

      It's possible to construct an entry from a bdecode_node, if a structure needs │ │ │ │ +to be altered and re-encoded.

      The integer(), string(), list() and dict() functions │ │ │ │ +are accessors that return the respective type. If the entry object │ │ │ │ +isn't of the type you request, the accessor will throw │ │ │ │ +system_error. You can ask an entry for its type through the │ │ │ │ +type() function.

      │ │ │ │ +

      If you want to create an entry you give it the type you want it to │ │ │ │ +have in its constructor, and then use one of the non-const accessors │ │ │ │ +to get a reference which you then can assign the value you want it to │ │ │ │ +have.

      The typical code to get info from a torrent file will then look like │ │ │ │ +this:

      │ │ │ │ +
      │ │ │ │ +entry torrent_file;
│ │ │ │ +// ...
│ │ │ │ +
│ │ │ │ +// throws if this is not a dictionary
│ │ │ │ +entry::dictionary_type const& dict = torrent_file.dict();
│ │ │ │ +entry::dictionary_type::const_iterator i;
│ │ │ │ +i = dict.find("announce");
│ │ │ │ +if (i != dict.end())
│ │ │ │ +{
│ │ │ │ +        std::string tracker_url = i->second.string();
│ │ │ │ +        std::cout << tracker_url << "\n";
│ │ │ │ +}
│ │ │ │ +
      │ │ │ │ +

      The following code is equivalent, but a little bit shorter:

      │ │ │ │ +
      │ │ │ │ +entry torrent_file;
│ │ │ │ +// ...
│ │ │ │ +
│ │ │ │ +// throws if this is not a dictionary
│ │ │ │ +if (entry* i = torrent_file.find_key("announce"))
│ │ │ │ +{
│ │ │ │ +        std::string tracker_url = i->string();
│ │ │ │ +        std::cout << tracker_url << "\n";
│ │ │ │ +}
│ │ │ │ +

      This function decodes/parses bdecoded data (for example a .torrent file). │ │ │ │ -The data structure is returned in the ret argument. the buffer to parse │ │ │ │ -is specified by the start of the buffer as well as the end, i.e. one │ │ │ │ -byte past the end. If the buffer fails to parse, the function returns a │ │ │ │ -non-zero value and fills in ec with the error code. The optional │ │ │ │ -argument error_pos, if set to non-nullptr, will be set to the byte offset │ │ │ │ -into the buffer where the parse failure occurred.

      │ │ │ │ -

      depth_limit specifies the max number of nested lists or dictionaries are │ │ │ │ -allowed in the data structure. (This affects the stack usage of the │ │ │ │ -function, be careful not to set it too high).

      │ │ │ │ -

      token_limit is the max number of tokens allowed to be parsed from the │ │ │ │ -buffer. This is simply a sanity check to not have unbounded memory usage.

      │ │ │ │ -

      The resulting bdecode_node is an owning node. That means it will │ │ │ │ -be holding the whole parsed tree. When iterating lists and dictionaries, │ │ │ │ -those bdecode_node objects will simply have references to the root or │ │ │ │ -owning bdecode_node. If the root node is destructed, all other nodes │ │ │ │ -that refer to anything in that tree become invalid.

      │ │ │ │ -

      However, the underlying buffer passed in to this function (start, end) │ │ │ │ -must also remain valid while the bdecoded tree is used. The parsed tree │ │ │ │ -produced by this function does not copy any data out of the buffer, but │ │ │ │ -simply produces references back into it.

      Bencoding is a common representation in bittorrent used for dictionary, │ │ │ │ -list, int and string hierarchies. It's used to encode .torrent files and │ │ │ │ -some messages in the network protocol. libtorrent also uses it to store │ │ │ │ -settings, resume data and other session state.

      │ │ │ │ -

      Strings in bencoded structures do not necessarily represent text. │ │ │ │ -Strings are raw byte buffers of a certain length. If a string is meant to be │ │ │ │ -interpreted as text, it is required to be UTF-8 encoded. See BEP 3.

      Declared in "libtorrent/bencode.hpp"

      │ │ │ │ -
      │ │ │ │ -template<class OutIt> int bencode (OutIt out, const entry& e);
│ │ │ │ -
      │ │ │ │ -

      This function will encode data to bencoded form.

      │ │ │ │ -

      The entry class is the internal representation of the bencoded data │ │ │ │ -and it can be used to retrieve information, an entry can also be build by │ │ │ │ -the program and given to bencode() to encode it into the OutIt │ │ │ │ -iterator.

      │ │ │ │ -

      OutIt is an OutputIterator. It's a template and usually │ │ │ │ -instantiated as ostream_iterator or back_insert_iterator. This │ │ │ │ -function assumes the value_type of the iterator is a char. │ │ │ │ -In order to encode entry e into a buffer, do:

      │ │ │ │ -
      │ │ │ │ -std::vector<char> buf;
│ │ │ │ -bencode(std::back_inserter(buf), e);

      This section describes the functions and classes that are used │ │ │ │ -to create torrent files. It is a layered API with low level classes │ │ │ │ -and higher level convenience functions. A torrent is created in 4 │ │ │ │ -steps:

      │ │ │ │ -
        │ │ │ │ -
      1. first the files that will be part of the torrent are determined.
        2. │ │ │ │ -
      2. the torrent properties are set, such as tracker url, web seeds, │ │ │ │ -DHT nodes etc.
        3. │ │ │ │ -
      3. Read through all the files in the torrent, SHA-1 all the data │ │ │ │ -and set the piece hashes.
        4. │ │ │ │ -
      4. The torrent is bencoded into a file or buffer.
        5. │ │ │ │ -
      │ │ │ │ -

      If there are a lot of files and or deep directory hierarchies to │ │ │ │ -traverse, step one can be time consuming.

      │ │ │ │ -

      Typically step 3 is by far the most time consuming step, since it │ │ │ │ -requires to read all the bytes from all the files in the torrent.

      │ │ │ │ -

      All of these classes and functions are declared by including │ │ │ │ -libtorrent/create_torrent.hpp.

      │ │ │ │ -

      example:

      │ │ │ │ -
      │ │ │ │ -file_storage fs;
│ │ │ │ -
│ │ │ │ -// recursively adds files in directories
│ │ │ │ -add_files(fs, "./my_torrent");

│ │ │ │ -std::vector<char> buf = t.generate_buf();
│ │ │ │ -out.write(buf.data(), buf.size());

│ │ │ │ -explicit create_torrent (torrent_info const& ti);
│ │ │ │ -
      │ │ │ │ -

      The piece_size is the size of each piece in bytes. It must be a │ │ │ │ -power of 2 and a minimum of 16 kiB. If a piece size of 0 is │ │ │ │ -specified, a piece_size will be set automatically. │ │ │ │ -Piece sizes greater than 128 MiB are considered unreasonable and will │ │ │ │ -be rejected (with an lt::system_error exception).

      │ │ │ │ -

      The flags arguments specifies options for the torrent creation. It can │ │ │ │ -be any combination of the flags defined by create_flags_t.

      │ │ │ │ -

      The file_storage (fs) parameter defines the files, sizes and │ │ │ │ -their properties for the torrent to be created. Set this up first, │ │ │ │ -before passing it to the create_torrent constructor.

      │ │ │ │ -

      The overload that takes a torrent_info object will make a verbatim │ │ │ │ -copy of its info dictionary (to preserve the info-hash). The copy of │ │ │ │ -the info dictionary will be used by create_torrent::generate(). This means │ │ │ │ -that none of the member functions of create_torrent that affects │ │ │ │ -the content of the info dictionary (such as set_hash()), will │ │ │ │ -have any affect.

      This function will generate the .torrent file as a bencode tree, or a │ │ │ │ -bencoded into a buffer. │ │ │ │ -In order to encode the entry into a flat file, use the bencode() function.

      │ │ │ │ -

      The function returning an entry may be useful to add custom entries │ │ │ │ -to the torrent file before bencoding it and saving it to disk.

      │ │ │ │ -

      Whether the resulting torrent object is v1, v2 or hybrid depends on │ │ │ │ -whether any of the v1_only or v2_only flags were set on the │ │ │ │ -constructor. If neither were set, the resulting torrent depends on │ │ │ │ -which hashes were set. If both v1 and v2 hashes were set, a hybrid │ │ │ │ -torrent is created.

      Any failure will cause this function to throw system_error, with an │ │ │ │ -appropriate error message. These are the reasons this call may throw:

      │ │ │ │ -
        │ │ │ │ -
      • the file storage has 0 files

      This sets the SHA-1 hash for the specified piece (index). You are required │ │ │ │ -to set the hash for every piece in the torrent before generating it. If you have │ │ │ │ -the files on disk, you can use the high level convenience function to do this. │ │ │ │ -See set_piece_hashes(). │ │ │ │ -A SHA-1 hash of all zeros is internally used to indicate a hash that │ │ │ │ -has not been set.

      This adds a url seed to the torrent. You can have any number of url seeds. For a │ │ │ │ -single file torrent, this should be an HTTP url, pointing to a file with identical │ │ │ │ -content as the file of the torrent. For a multi-file torrent, it should point to │ │ │ │ -a directory containing a directory with the same name as this torrent, and all the │ │ │ │ -files of the torrent in it.

      Adds a tracker to the torrent. This is not strictly required, but most torrents │ │ │ │ -use a tracker as their main source of peers. The url should be an http:// or udp:// │ │ │ │ -url to a machine running a bittorrent tracker that accepts announces for this torrent's │ │ │ │ -info-hash. The tier is the fallback priority of the tracker. All trackers with tier 0 are │ │ │ │ -tried first (in any order). If all fail, trackers with tier 1 are tried.

      This function sets an X.509 certificate in PEM format to the torrent. This makes the │ │ │ │ -torrent an SSL torrent. An SSL torrent requires that each peer has a valid certificate │ │ │ │ -signed by this root certificate. For SSL torrents, all peers are connecting over SSL │ │ │ │ -connections.

│ │ │ +These can be general extensions for transferring metadata or peer exchange │ │ │ │ │ +extensions, or it could be used to provide a way to customize the protocol to │ │ │ │ │ +fit a particular (closed) network. │ │ │ │ │ +In short, the _p_l_u_g_i_n interface makes it possible to: │ │ │ │ │ + * register extension messages (sent in the extension handshake), see │ │ │ │ │ + _e_x_t_e_n_s_i_o_n_s. │ │ │ │ │ + * add data and parse data from the extension handshake. │ │ │ │ │ + * send extension messages and standard bittorrent messages. │ │ │ │ │ + * override or block the handling of standard bittorrent messages. │ │ │ │ │ + * save and restore state via the _s_e_s_s_i_o_n state │ │ │ │ │ + * see all alerts that are posted │ │ │ │ │ +************ aa wwoorrdd ooff ccaauuttiioonn ************ │ │ │ │ │ +Writing your own _p_l_u_g_i_n is a very easy way to introduce serious bugs such as │ │ │ │ │ +dead locks and race conditions. Since a _p_l_u_g_i_n has access to internal │ │ │ │ │ +structures it is also quite easy to sabotage libtorrent's operation. │ │ │ │ │ +All the callbacks are always called from the libtorrent network thread. In case │ │ │ │ │ +portions of your _p_l_u_g_i_n are called from other threads, typically the main │ │ │ │ │ +thread, you cannot use any of the member functions on the internal structures │ │ │ │ │ +in libtorrent, since those require being called from the libtorrent network │ │ │ │ │ +thread . Furthermore, you also need to synchronize your own shared data within │ │ │ │ │ +the _p_l_u_g_i_n, to make sure it is not accessed at the same time from the │ │ │ │ │ +libtorrent thread (through a callback). If you need to send out a message from │ │ │ │ │ +another thread, it is advised to use an internal queue, and do the actual │ │ │ │ │ +sending in tick(). │ │ │ │ │ +Since the _p_l_u_g_i_n interface gives you easy access to internal structures, it is │ │ │ │ │ +not supported as a stable API. Plugins should be considered specific to a │ │ │ │ │ +specific version of libtorrent. Although, in practice the internals mostly │ │ │ │ │ +don't change that dramatically. │ │ │ │ │ +************ pplluuggiinn--iinntteerrffaaccee ************ │ │ │ │ │ +The _p_l_u_g_i_n interface consists of three base classes that the _p_l_u_g_i_n may │ │ │ │ │ +implement. These are called _p_l_u_g_i_n, _t_o_r_r_e_n_t___p_l_u_g_i_n and _p_e_e_r___p_l_u_g_i_n. They are │ │ │ │ │ +found in the header. │ │ │ │ │ +These plugins are instantiated for each _s_e_s_s_i_o_n, torrent and possibly each │ │ │ │ │ +peer, respectively. │ │ │ │ │ +For plugins that only need per torrent state, it is enough to only implement │ │ │ │ │ +torrent_plugin and pass a constructor function or function object to session:: │ │ │ │ │ +add_extension() or torrent_handle::add_extension() (if the torrent has already │ │ │ │ │ +been started and you want to hook in the extension at run-time). │ │ │ │ │ +The signature of the function is: │ │ │ │ │ +std::shared_ptr (*)(torrent_handle const&, client_data_t); │ │ │ │ │ +The second argument is the userdata passed to session::add_torrent() or │ │ │ │ │ +torrent_handle::add_extension(). │ │ │ │ │ +The function should return a std::shared_ptr which may or may │ │ │ │ │ +not be 0. If it is a nullptr, the extension is simply ignored for this torrent. │ │ │ │ │ +If it is a valid pointer (to a class inheriting torrent_plugin), it will be │ │ │ │ │ +associated with this torrent and callbacks will be made on torrent events. │ │ │ │ │ +For more elaborate plugins which require _s_e_s_s_i_o_n wide state, you would │ │ │ │ │ +implement plugin, construct an object (in a std::shared_ptr) and pass it in to │ │ │ │ │ +session::add_extension(). │ │ │ │ │ +************ ccuussttoomm aalleerrttss ************ │ │ │ │ │ +Since plugins are running within internal libtorrent threads, one convenient │ │ │ │ │ +way to communicate with the client is to post custom alerts. │ │ │ │ │ +The expected interface of any _a_l_e_r_t, apart from deriving from the _a_l_e_r_t base │ │ │ │ │ +class, looks like this: │ │ │ │ │ +static const int alert_type = <>; │ │ │ │ │ +virtual int type() const { return alert_type; } │ │ │ │ │ + │ │ │ │ │ +virtual std::string message() const; │ │ │ │ │ + │ │ │ │ │ +static const alert_category_t static_category = <>; │ │ │ │ │ +virtual alert_category_t category() const { return static_category; } │ │ │ │ │ + │ │ │ │ │ +virtual char const* what() const { return <>; } │ │ │ │ │ +The alert_type is used for the type-checking in alert_cast. It must not collide │ │ │ │ │ +with any other _a_l_e_r_t. The built-in alerts in libtorrent will not use _a_l_e_r_t type │ │ │ │ │ +IDs greater than user_alert_id. When defining your own _a_l_e_r_t, make sure it's │ │ │ │ │ +greater than this constant. │ │ │ │ │ +type() is the run-time equivalence of the alert_type. │ │ │ │ │ +The message() virtual function is expected to construct a useful string │ │ │ │ │ +representation of the _a_l_e_r_t and the event or data it represents. Something │ │ │ │ │ +convenient to put in a log file for instance. │ │ │ │ │ +clone() is used internally to copy alerts. The suggested implementation of │ │ │ │ │ +simply allocating a new instance as a copy of *this is all that's expected. │ │ │ │ │ +The static category is required for checking whether or not the category for a │ │ │ │ │ +specific _a_l_e_r_t is enabled or not, without instantiating the _a_l_e_r_t. The category │ │ │ │ │ +virtual function is the run-time equivalence. │ │ │ │ │ +The what() virtual function may simply be a string literal of the class name of │ │ │ │ │ +your _a_l_e_r_t. │ │ │ │ │ +For more information, see the _a_l_e_r_t_ _s_e_c_t_i_o_n. │ │ │ │ │ [_r_e_p_o_r_t_ _i_s_s_u_e] │ │ │ │ │ -************ ppiieeccee__bblloocckk ************ │ │ │ │ │ -Declared in "_l_i_b_t_o_r_r_e_n_t_/_p_i_e_c_e___b_l_o_c_k_._h_p_p" │ │ │ │ │ -struct piece_block │ │ │ │ │ +************ ppeeeerr__ccoonnnneeccttiioonn__hhaannddllee ************ │ │ │ │ │ +Declared in "_l_i_b_t_o_r_r_e_n_t_/_p_e_e_r___c_o_n_n_e_c_t_i_o_n___h_a_n_d_l_e_._h_p_p" │ │ │ │ │ +the _p_e_e_r___c_o_n_n_e_c_t_i_o_n___h_a_n_d_l_e class provides a handle to the internal peer │ │ │ │ │ +connection object, to be used by plugins.

It is a layered API with low level classes and higher level │ │ │ │ │ +convenience functions. A torrent is created in 4 steps: │ │ │ │ │ + 1. first the files that will be part of the torrent are determined. │ │ │ │ │ + 2. the torrent properties are set, such as tracker url, web seeds, DHT nodes │ │ │ │ │ + etc. │ │ │ │ │ + 3. Read through all the files in the torrent, SHA-1 all the data and set the │ │ │ │ │ + piece hashes. │ │ │ │ │ + 4. The torrent is bencoded into a file or buffer. │ │ │ │ │ +If there are a lot of files and or deep directory hierarchies to traverse, step │ │ │ │ │ +one can be time consuming. │ │ │ │ │ +Typically step 3 is by far the most time consuming step, since it requires to │ │ │ │ │ +read all the bytes from all the files in the torrent. │ │ │ │ │ +All of these classes and functions are declared by including libtorrent/ │ │ │ │ │ +create_torrent.hpp. │ │ │ │ │ +example: │ │ │ │ │ +file_storage fs; │ │ │ │ │ + │ │ │ │ │ +// recursively adds files in directories │ │ │ │ │ +add_files(fs, "./my_torrent"); │ │ │ │ │ + │ │ │ │ │ +create_torrent t(fs); │ │ │ │ │ +t.add_tracker("http://my.tracker.com/announce"); │ │ │ │ │ +t.set_creator("libtorrent example"); │ │ │ │ │ + │ │ │ │ │ +// reads the files and calculates the hashes │ │ │ │ │ +set_piece_hashes(t, "."); │ │ │ │ │ + │ │ │ │ │ +ofstream out("my_torrent.torrent", std::ios_base::binary); │ │ │ │ │ +std::vector buf = t.generate_buf(); │ │ │ │ │ +out.write(buf.data(), buf.size()); │ │ │ │ │ + │ │ │ │ │ +// alternatively, generate an entry and encode it directly to an ostream │ │ │ │ │ +// iterator │ │ │ │ │ +bencode(std::ostream_iterator(out), t.generate()); │ │ │ │ │ +[_r_e_p_o_r_t_ _i_s_s_u_e] │ │ │ │ │ +************ ccrreeaattee__ttoorrrreenntt ************ │ │ │ │ │ +Declared in "_l_i_b_t_o_r_r_e_n_t_/_c_r_e_a_t_e___t_o_r_r_e_n_t_._h_p_p" │ │ │ │ │ +This class holds state for creating a torrent.

If a hash fails, │ │ │ │ │ - the torrent will automatically leave the seed mode and recheck all the │ │ │ │ │ - files. The use case for this mode is if a torrent is created and seeded, │ │ │ │ │ - or if the user already know that the files are complete, this is a way to │ │ │ │ │ - avoid the initial file checks, and significantly reduce the startup time. │ │ │ │ │ - Setting seed_mode on a torrent without metadata (a .torrent file) is a │ │ │ │ │ - no-op and will be ignored. │ │ │ │ │ - It is not possible to sseett the seed_mode flag on a torrent after it has │ │ │ │ │ - been added to a _s_e_s_s_i_o_n. It is possible to cclleeaarr it though. │ │ │ │ │ - upload_mode │ │ │ │ │ - If upload_mode is set, the torrent will be initialized in upload-mode, │ │ │ │ │ - which means it will not make any piece requests. This state is typically │ │ │ │ │ - entered on disk I/O errors, and if the torrent is also auto managed, it │ │ │ │ │ - will be taken out of this state periodically (see settings_pack:: │ │ │ │ │ - optimistic_disk_retry). │ │ │ │ │ - This mode can be used to avoid race conditions when adjusting priorities │ │ │ │ │ - of pieces before allowing the torrent to start downloading. │ │ │ │ │ - If the torrent is auto-managed (auto_managed), the torrent will │ │ │ │ │ - eventually be taken out of upload-mode, regardless of how it got there. │ │ │ │ │ - If it's important to manually control when the torrent leaves upload │ │ │ │ │ - mode, don't make it auto managed. │ │ │ │ │ - share_mode │ │ │ │ │ - determines if the torrent should be added in sshhaarree mmooddee or not. Share │ │ │ │ │ - mode indicates that we are not interested in downloading the torrent, but │ │ │ │ │ - merely want to improve our share ratio (i.e. increase it). A torrent │ │ │ │ │ - started in share mode will do its best to never download more than it │ │ │ │ │ - uploads to the swarm. If the swarm does not have enough demand for upload │ │ │ │ │ - capacity, the torrent will not download anything. This mode is intended │ │ │ │ │ - to be safe to add any number of torrents to, without manual screening, │ │ │ │ │ - without the risk of downloading more than is uploaded. │ │ │ │ │ - A torrent in share mode sets the priority to all pieces to 0, except for │ │ │ │ │ - the pieces that are downloaded, when pieces are decided to be downloaded. │ │ │ │ │ - This affects the progress bar, which might be set to "100% finished" most │ │ │ │ │ - of the time. Do not change file or piece priorities for torrents in share │ │ │ │ │ - mode, it will make it not work. │ │ │ │ │ - The share mode has one setting, the share ratio target, see │ │ │ │ │ - settings_pack::share_mode_target for more info. │ │ │ │ │ - apply_ip_filter │ │ │ │ │ - determines if the IP filter should apply to this torrent or not. By │ │ │ │ │ - default all torrents are subject to filtering by the IP filter (i.e. this │ │ │ │ │ - flag is set by default). This is useful if certain torrents needs to be │ │ │ │ │ - exempt for some reason, being an auto-update torrent for instance. │ │ │ │ │ - paused │ │ │ │ │ - specifies whether or not the torrent is paused. i.e. it won't connect to │ │ │ │ │ - the tracker or any of the peers until it's resumed. Note that a paused │ │ │ │ │ - torrent that also has the auto_managed flag set can be started at any │ │ │ │ │ - time by libtorrent's queuing logic. See _q_u_e_u_i_n_g. │ │ │ │ │ - auto_managed │ │ │ │ │ - If the torrent is auto-managed (auto_managed), the torrent may be resumed │ │ │ │ │ - at any point, regardless of how it paused. If it's important to manually │ │ │ │ │ - control when the torrent is paused and resumed, don't make it auto │ │ │ │ │ - managed. │ │ │ │ │ - If auto_managed is set, the torrent will be queued, started and seeded │ │ │ │ │ - automatically by libtorrent. When this is set, the torrent should also be │ │ │ │ │ - started as paused. The default queue order is the order the torrents were │ │ │ │ │ - added. They are all downloaded in that order. For more details, see │ │ │ │ │ - _q_u_e_u_i_n_g. │ │ │ │ │ - duplicate_is_error │ │ │ │ │ - used in _a_d_d___t_o_r_r_e_n_t___p_a_r_a_m_s to indicate that it's an error to attempt to │ │ │ │ │ - add a torrent that's already in the _s_e_s_s_i_o_n.

This flag is not │ │ │ │ │ - saved by _w_r_i_t_e___r_e_s_u_m_e___d_a_t_a_(_), since it is only meant for adding torrents. │ │ │ │ │ - update_subscribe │ │ │ │ │ - on by default and means that this torrent will be part of state updates │ │ │ │ │ - when calling _p_o_s_t___t_o_r_r_e_n_t___u_p_d_a_t_e_s_(_). This flag is not saved by │ │ │ │ │ - _w_r_i_t_e___r_e_s_u_m_e___d_a_t_a_(_). │ │ │ │ │ - super_seeding │ │ │ │ │ - sets the torrent into super seeding/initial seeding mode. If the torrent │ │ │ │ │ - is not a seed, this flag has no effect. │ │ │ │ │ - sequential_download │ │ │ │ │ - sets the sequential download state for the torrent. In this mode the │ │ │ │ │ - piece picker will pick pieces with low index numbers before pieces with │ │ │ │ │ - high indices. The actual pieces that are picked depend on other factors │ │ │ │ │ - still, such as which pieces a peer has and whether it is in parole mode │ │ │ │ │ - or "prefer whole pieces"-mode. Sequential mode is not ideal for streaming │ │ │ │ │ - media. For that, see _s_e_t___p_i_e_c_e___d_e_a_d_l_i_n_e_(_) instead. │ │ │ │ │ - stop_when_ready │ │ │ │ │ - When this flag is set, the torrent will ffoorrccee ssttoopp whenever it │ │ │ │ │ - transitions from a non-data-transferring state into a data-transferring │ │ │ │ │ - state (referred to as being ready to download or seed). This is useful │ │ │ │ │ - for torrents that should not start downloading or seeding yet, but want │ │ │ │ │ - to be made ready to do so. A torrent may need to have its files checked │ │ │ │ │ - for instance, so it needs to be started and possibly queued for checking │ │ │ │ │ - (auto-managed and started) but as soon as it's done, it should be │ │ │ │ │ - stopped. │ │ │ │ │ - FFoorrccee ssttooppppeedd means auto-managed is set to false and it's paused. As if │ │ │ │ │ - the auto_manages flag is cleared and the paused flag is set on the │ │ │ │ │ - torrent. │ │ │ │ │ - Note that the torrent may transition into a downloading state while │ │ │ │ │ - setting this flag, and since the logic is edge triggered you may miss the │ │ │ │ │ - edge. To avoid this race, if the torrent already is in a downloading │ │ │ │ │ - state when this call is made, it will trigger the stop-when-ready │ │ │ │ │ - immediately. │ │ │ │ │ - When the stop-when-ready logic fires, the flag is cleared. Any subsequent │ │ │ │ │ - transitions between downloading and non-downloading states will not be │ │ │ │ │ - affected, until this flag is set again. │ │ │ │ │ - The behavior is more robust when setting this flag as part of adding the │ │ │ │ │ - torrent. See _a_d_d___t_o_r_r_e_n_t___p_a_r_a_m_s. │ │ │ │ │ - The stop-when-ready flag fixes the inherent race condition of waiting for │ │ │ │ │ - the _s_t_a_t_e___c_h_a_n_g_e_d___a_l_e_r_t and then call _p_a_u_s_e_(_). The download/seeding will │ │ │ │ │ - most likely start in between posting the _a_l_e_r_t and receiving the call to │ │ │ │ │ - pause. │ │ │ │ │ - A downloading state is one where peers are being connected. Which means │ │ │ │ │ - just downloading the metadata via the ut_metadata extension counts as a │ │ │ │ │ - downloading state. In order to stop a torrent once the metadata has been │ │ │ │ │ - downloaded, instead set all file priorities to dont_download │ │ │ │ │ - override_trackers │ │ │ │ │ - when this flag is set, the tracker list in the _a_d_d___t_o_r_r_e_n_t___p_a_r_a_m_s object │ │ │ │ │ - override any trackers from the torrent file. If the flag is not set, the │ │ │ │ │ - trackers from the _a_d_d___t_o_r_r_e_n_t___p_a_r_a_m_s object will be added to the list of │ │ │ │ │ - trackers used by the torrent. This flag is set by _r_e_a_d___r_e_s_u_m_e___d_a_t_a_(_) if │ │ │ │ │ - there are trackers present in the resume data file. This effectively │ │ │ │ │ - makes the trackers saved in the resume data take precedence over the │ │ │ │ │ - original trackers.

This may be used when │ │ │ │ │ - restoring a _s_e_s_s_i_o_n by loading resume data from disk. It will save time │ │ │ │ │ - and also delay any hard disk errors until files are actually needed. If │ │ │ │ │ - the resume data cannot be trusted, or if a torrent is added for the first │ │ │ │ │ - time to some save path that may already have some of the files, this flag │ │ │ │ │ - should not be set. │ │ │ │ │ - default_dont_download │ │ │ │ │ - default all file priorities to dont_download. This is useful for adding │ │ │ │ │ - magnet links where the number of files is unknown, but the │ │ │ │ │ - file_priorities is still set for some files. Any file not covered by the │ │ │ │ │ - file_priorities list will be set to normal download priority, unless this │ │ │ │ │ - flag is set, in which case they will be set to 0 (dont_download). │ │ │ │ │ - i2p_torrent │ │ │ │ │ - this flag makes the torrent be considered an "i2p torrent" for purposes │ │ │ │ │ - of the allow_i2p_mixed setting.

This state is typically │ │ │ │ │ + entered on disk I/O errors, and if the torrent is also auto managed, it │ │ │ │ │ + will be taken out of this state periodically (see settings_pack:: │ │ │ │ │ + optimistic_disk_retry). │ │ │ │ │ + This mode can be used to avoid race conditions when adjusting priorities │ │ │ │ │ + of pieces before allowing the torrent to start downloading. │ │ │ │ │ + If the torrent is auto-managed (auto_managed), the torrent will │ │ │ │ │ + eventually be taken out of upload-mode, regardless of how it got there. │ │ │ │ │ + If it's important to manually control when the torrent leaves upload │ │ │ │ │ + mode, don't make it auto managed. │ │ │ │ │ + share_mode │ │ │ │ │ + determines if the torrent should be added in sshhaarree mmooddee or not. Share │ │ │ │ │ + mode indicates that we are not interested in downloading the torrent, but │ │ │ │ │ + merely want to improve our share ratio (i.e. increase it). A torrent │ │ │ │ │ + started in share mode will do its best to never download more than it │ │ │ │ │ + uploads to the swarm. If the swarm does not have enough demand for upload │ │ │ │ │ + capacity, the torrent will not download anything. This mode is intended │ │ │ │ │ + to be safe to add any number of torrents to, without manual screening, │ │ │ │ │ + without the risk of downloading more than is uploaded. │ │ │ │ │ + A torrent in share mode sets the priority to all pieces to 0, except for │ │ │ │ │ + the pieces that are downloaded, when pieces are decided to be downloaded. │ │ │ │ │ + This affects the progress bar, which might be set to "100% finished" most │ │ │ │ │ + of the time. Do not change file or piece priorities for torrents in share │ │ │ │ │ + mode, it will make it not work. │ │ │ │ │ + The share mode has one setting, the share ratio target, see │ │ │ │ │ + settings_pack::share_mode_target for more info. │ │ │ │ │ + apply_ip_filter │ │ │ │ │ + determines if the IP filter should apply to this torrent or not. By │ │ │ │ │ + default all torrents are subject to filtering by the IP filter (i.e. this │ │ │ │ │ + flag is set by default). This is useful if certain torrents needs to be │ │ │ │ │ + exempt for some reason, being an auto-update torrent for instance. │ │ │ │ │ + paused │ │ │ │ │ + specifies whether or not the torrent is paused. i.e. it won't connect to │ │ │ │ │ + the tracker or any of the peers until it's resumed. Note that a paused │ │ │ │ │ + torrent that also has the auto_managed flag set can be started at any │ │ │ │ │ + time by libtorrent's queuing logic. See _q_u_e_u_i_n_g. │ │ │ │ │ + auto_managed │ │ │ │ │ + If the torrent is auto-managed (auto_managed), the torrent may be resumed │ │ │ │ │ + at any point, regardless of how it paused.

For that, see _s_e_t___p_i_e_c_e___d_e_a_d_l_i_n_e_(_) instead. │ │ │ │ │ + stop_when_ready │ │ │ │ │ + When this flag is set, the torrent will ffoorrccee ssttoopp whenever it │ │ │ │ │ + transitions from a non-data-transferring state into a data-transferring │ │ │ │ │ + state (referred to as being ready to download or seed). This is useful │ │ │ │ │ + for torrents that should not start downloading or seeding yet, but want │ │ │ │ │ + to be made ready to do so. A torrent may need to have its files checked │ │ │ │ │ + for instance, so it needs to be started and possibly queued for checking │ │ │ │ │ + (auto-managed and started) but as soon as it's done, it should be │ │ │ │ │ + stopped. │ │ │ │ │ + FFoorrccee ssttooppppeedd means auto-managed is set to false and it's paused. As if │ │ │ │ │ + the auto_manages flag is cleared and the paused flag is set on the │ │ │ │ │ + torrent. │ │ │ │ │ + Note that the torrent may transition into a downloading state while │ │ │ │ │ + setting this flag, and since the logic is edge triggered you may miss the │ │ │ │ │ + edge. To avoid this race, if the torrent already is in a downloading │ │ │ │ │ + state when this call is made, it will trigger the stop-when-ready │ │ │ │ │ + immediately. │ │ │ │ │ + When the stop-when-ready logic fires, the flag is cleared.
