release/2.0.11.0 (beta)

Welcome to jlibtorrent 2.0.11.0

This is our first build of jlibtorrent-2.0, all tests are passing but we have yet to integrate the library with a production bittorrent client such as FrostWire for Desktop and FrostWire for Android.

We'll be doing so over the next weeks, and once we've throughly tested everything is working as expected we'll promote our next build (if necessary) to a stable release you can use to update your app to support bittorrent 2.0 features, plus all the fixes in libtorrent made the last 15 months.

  • Operator Renaming:

    • Mapped C++ operators to Java-friendly method names using %rename directives:
      • operator== to op_eq
      • operator!= to op_ne
      • operator< to op_lt
      • operator> to op_gt
      • operator<= to op_lte

    • Included boost_system_error_code.i for proper error handling.

• Build Scripts and Dependencies

  • Added New Build Options:

    • Introduced --swig-only and --build-only options to the SWIG/build scripts (run-swig.sh and build.sh).
      • --swig-only: Executes only the SWIG interface generation without initiating the build process.
      • --build-only: Runs only the build process using pre-generated SWIG wrappers, skipping the SWIG generation phase.
    • These options provide developers with greater flexibility during development and testing by allowing selective execution of build stages.

  • Build Script Enhancements:

    • Added prepare-macos.sh script to automate the installation of dependencies and the required SWIG version on macOS systems.
      • Installs necessary packages using Homebrew (wget, pcre2).
      • Checks and installs SWIG version 4.2.1 if not already present.
      • Verifies successful installation post-build.
    • Updated run-swig.sh script to handle platform-specific code adjustments and ensure correct SWIG version usage.
      • Implemented additional sed commands to fix code issues in libtorrent headers before SWIG processing.
      • Added safeguards to handle SWIG failures gracefully, providing informative messages and exiting if necessary.
      • Updated build flags and configurations to align with the latest libtorrent ABI versions.
      • Set TORRENT_ABI_VERSION=4 and updated namespaces for versions 3 and 4.

• Dependency Upgrades

  • Boost Upgrade:

    • Upgraded Boost library to version 1.86.0 to improve performance and compatibility.

  • OpenSSL Upgrade:

    • Updated OpenSSL to version 1.1.1t to enhance security and support the latest protocols.

  • Gradle Upgrade:

    • Upgraded Gradle to version 8.10.2 to leverage new features and improvements in build automation.

  • Java Development Kit (JDK):

    • Jar built with JDK 11, ensuring compatibility with the build environment.

  • Libtorrent Update:

    • Updated libtorrent to RC_2_0 (rev: 2ab8fedabb7716947edc77958da6d0b5e1040df9) to incorporate the latest fixes and features from the libtorrent 2.0 branch.

  • Android NDK Upgrade:

    • Upgraded Android NDK to version r26d (LTS) from r25c, providing the latest toolchains and platform support.

  • SWIG Upgrade:

    • Upgraded SWIG to version 4.2.1 to improve interface generation and support new language features.

• Exception and Error Handling

  • Enhanced Exception Handling:
    • Improved exception translation from C++ to Java within SWIG interfaces to ensure robust error management.

• Compatibility and Performance Fixes

  • Fixed Compatibility Issues:

    • Resolved syntax issues in file_storage.hpp and ip_filter.hpp to ensure successful SWIG processing and avoid compilation errors.
    • Adjusted build flags and macros for Boost and libtorrent compatibility across different platforms.

  • Performance Optimizations:

    • Optimized SWIG typemaps and wrappers for efficient data handling, minimizing performance overhead in Java bindings.

• Directors and Inheritance

  • Enabled SWIG Directors:
    • Enabled directors for classes requiring Java-side inheritance, facilitating the overriding of C++ virtual methods in Java subclasses:
      • add_files_listener
      • set_piece_hashes_listener
      • alert_notify_callback
      • swig_plugin
      • posix_wrapper

• Code Clean-up and Maintenance

  • Ignored Deprecated and Internal Elements:

    • Excluded numerous deprecated methods, internal functions, and classes from the SWIG interface to streamline Java bindings and prevent potential conflicts.

  • Removed Redundant Code:

    • Deleted unnecessary %ignore directives and obsolete SWIG configurations to maintain a clean and maintainable interface.

  • Enhanced Documentation:

    • Improved comments and added TODOs for future integrations, such as web_seed_entry.hpp once merged from the master branch.
