    Date:

    🆕 New Features:

    🐛 Bug Fixes/Improvements:

  • v1.10 Changes

    Date: 12/05/2021

    🆕 New Features:

    • API to create torrent metainfo (.torrent files)
    • ⚡️ Update Guice to 5.0.1 for Java 9 support
    • 👌 Support callback functions for when
      • Torrent files complete downloading
      • The entire torrent completes downloading
    • ChooseFilesStage now allows SKIPPED, NORMAL_PRIORITY, and HIGH_PRIORITY for downloading
      • File download priority can be mutated while the torrent is downloaded. Skipping or unskipping files while the torrent is downloading is not supported.
    • ➕ Add config switch to completely disable MSE negotiation
    • ➕ Add config parameter for the time interval between reads in MSE negotiation
    • ➕ Add config parameter for the max number of simultaneously assigned pieces for a single peer
    • ➕ Add config parameter for the IP address to send to the tracker (for remote peers to use). Useful when behind a NAT. Only supported for http trackers currently.
    • ➕ Add runtime builder methods for disabling PEX and LSD extensions

    🐛 Bug Fixes/Improvements:

    • 👍 Allow announce key to be missing in the torrent dictionary #42
    • 🐎 bt.data.digest.JavaSecurityDigester performance improvement #133
    • 🛠 Fix NullPointerException in SocketChannelHandler.flush()
    • 👻 Do not throw "Unexpectedly interrupted" exception when message loop is shutdown
    • 🛠 Fix missing breaks in MetadataFetchStage which could led to hang-ups
    • Indicate the listening TCP port in thread names
    • 🛠 Fix ConcurrentModificationException in LocalServiceDiscoveryService
    • 🛠 Fix memory leak in BtRuntime by making sure that shutdown hook is removed after shutdown is complete
    • 🛠 Fix memory leak in event bus mechanism by making sure that torrent listeners are removed when torrent is stopped
    • Ensure that torrent descriptor is inactivated when BtClient.stop() is invoked
    • Multiple minor improvements to reduce memory allocations
    • More descriptive error message when there's insufficient room in buffer to read an integer
    • 🛠 Implement LRU cache for open file handles (fixes issues with torrents with many files)
    • 🛠 Fix NullPointerException in AdhocTorrentRegistry.unregister(TorrentId)
    • ⚡️ Updated the file I/O APIs to use FileChannel read/write so that multiple threads can concurrently read/write to different sections of an open file
    • ➕ Add API to forcefully flush torrent data to persistent storage
    • 🐎 BTInteger uses Integer, Long, or BigInteger depending upon the number for space/performance savings
    • 👀 Download stage now uses a latch, rather than sleeping, to determine when the download is finished to go onto the seeding stage
    • ⚡️ Eliminate a 1 second wait for the initial torrent download by updating interested peers immediately if there are currently zero peers that the client is interested in
    • Torrent chunk verification now uses Stream APIs with a custom ForkJoinPool (if a desired amount of parallelism is requested) rather than an executor
    • 0️⃣ DefaultDataDescriptor.filesForPieces now uses a List for indices rather than a map
    • LocalBitfield now uses a Copy On Write (COW) strategy for skipped pieces rathen than locking
    • PeerBitfields are read with BitSet.valueOf() rather than setting each Bit individually
    • Irrelevant pieces are filtered out of a bitset before they reach the piece selectors
    • The rarest piece selector now uses bucket sort based on max peer count rather than a MinHeap
    • The randomized rarest piece selector uses a precomputed random shuffle order to reduce the overhead of random piece shuffling
    • 🛠 Fix double release issue in DefaultBorrowedBuffer, which eliminates the harmless exception "Buffer is locked and can't be released" that occured sometimes
    • 🛠 Fix intermittent NullPointerException in DHT shutdown hook
    • 🌲 Lower logging level to debug on peer disconnects
    • 🔒 Eliminate possibility of a dead lock in peer connection handling code #170
    • 🆕 New configuration option for adjusting the amount of memory used for hashing (verification) of data
    • 🛠 Fix a dead-lock in SocketChannelHandler #183
    • ⚙ Runtime does not terminate when torrent has been downloaded #167
    • Peers received from the initial tracker connection are now used rather than discarded
    • Bt no longer makes two calls to the tracker on startup - one to announce the startup and the other to get peers.
    • Bt now respects tracker minimum announce intervals
    • Bt now does not send a completed event to the tracker if the torrent was already completed before it connected to the tracker
    • 🔀 The first tracker announce is synchronously waited for - this decreases the time to connect to the first peers returned from the tracker.
    • 🛠 Fix bug that prevents plain text clients from connecting when MSE encryption is enabled
