HANDSHAKE_LENGTH

const int64_t fur::download::downloader::HANDSHAKE_LENGTH = 1 + 19 + 8 + 20 + 20

Length (in bytes) of a BitTorrent handshake.

INFO_HASH_OFFSET

const int64_t fur::download::downloader::INFO_HASH_OFFSET = 1 + 19 + 8

Offset (in bytes) from the beginning of a BitTorrent handshake for the info-hash field.

UNCHOKE_TIMEOUT

const int64_t fur::download::downloader::UNCHOKE_TIMEOUT = 15

Should be greater than 10 seconds for a realistic torrent client but smaller values result in quicker testing
