Change log

1.5.0

  • Upgraded LZ4 to 1.8.3. Updated JNI bindings for Linux/amd64, Linux/ppc64le, Linux/s390x, Linux/aarch64, and Mac OS Darwin/x86_64. A speed-up is expected on these platforms. Note that the JNI bindings for Linux/i386 and Win32 still work but are based on old LZ4 r123. Contributions of the JNI bindings for these and other platforms are more than welcome.

  • #119 Implemented LZ4CompressorWithLength, which includes the length of the original decompressed data in the output compressed data, and corresponding LZ4DecompressorWithLength. (Rei Odaira)

  • #118 Added build status to README. (Daniel Yu)

  • #116 Changed LZ4BlockOutputStream and LZ4BlockInputStream to non-final for better testing support. (Rei Odaira)

  • #113 Compressor and checksum can be specified for LZ4FrameOutputStream. (Elan Kugelmass)

  • #111 Added lz4 sources as a git submodule. (Daniel Yu)

  • #110 Enabled Travis CI. (Daniel Yu)

  • Better test coverage. (Rei Odaira)

  • Supported build with Java 9. Note that the distribution is still built with Java 7. (Rei Odaira)

1.4.1

  • #120 Fixed LZ4{Block|Frame}InputStream.skip() to return 0 when n <= 0 or EOF. (Xiaoyan Lin)

  • #117 Fixed LZ4FrameInputStream.read() to return a correct value when reading a byte >= 128. (sorenop)

  • #109 Updated xxHash URL in README.md. (lyrachord)

  • Improved the documentation. (Rei Odaira)

1.4.0

  • The project page has been moved to https://github.com/lz4/lz4-java. (Adrien Grand, Yann Collet)

  • groupId and artifactId have been changed from net.jpountz.lz4 and lz4 to org.lz4 and lz4-java, respectively. (Rei Odaira)

  • #105 LZ4BlockInputStream can read concatenated streams. (Takeshi Yamamuro, Davies Liu)

  • #99 LZ4FrameInputStream allows EndMark to be incompressible. (Charles Allen)

  • #95 Added unsafe instance support for aarch64. (Yuqi Gu)

  • #93 Added unsafe instance support for ppc64le. (Madhusudanan Kandasamy)

  • #90 LZ4 Java now supports 64-bit JNI build on Solaris. (cndcourt)

  • #86 Added a pre-built JNI binding for aarch64. (Rocky Zhang)

  • #85 Added a pre-built JNI binding for s390x. (Rei Odaira)

  • #84 Added a pre-built JNI binding for ppc64le. (Rei Odaira)

  • #83 LZ4 Java tries to load a JNI binding from java.library.path first, and then fall back to bundled one. (Jakub Jirutka)

  • #70 and #89 Avoid over-allocating a buffer in LZ4BlockInputStream. (Marko Topolnik)

  • #65 Fixed ByteBuffer methods failing to apply arrayOffset() for array-backed buffers. (Branimir Lambov)

  • #63 All resources are placed under the net.jpountz package to support the maven shade plugin. (Chris Lockfort)

  • #61 Added LZ4 Frame version 1.5.1 support. (Charles Allen)

  • #60 Fixed NullPointerException in LZ4Factory and XXHashFactory when they are loaded by the bootstrap classloader. (Yilong Li)

  • #53 Fixed calling flush on closed LZ4BlockOutputStream. (Will Droste)

1.3.0

  • lz4 r123

  • xxhash r37

  • #49 All compression and decompression routines as well as xxhash can now work with java.nio.ByteBuffer. (Branimir Lambov)

  • #46 Fixed incorrect usage of ReleasePrimitiveArrayCritical. (Xiaoguang Sun)

  • #44 Added support for xxhash64. (Linnaea Von Lavia)

  • #43 The compression level for high compression is now configurable. (Linnaea Von Lavia)

  • #39 The JAR is now a valid OSGI bundle. (Simon Chemouil)

  • #33 The implementation based on Java's sun.misc.Unsafe relies on unaligned memory access and is now only used on platforms that support it. (Dmitry Shohov)

1.2.0

  • lz4 r100

  • #16 Fix violation of the Closeable contract in LZ4BlockOutputStream: double close now works as specified in the Closeable interface documentation. (Steven Schlansker)

  • #17 The JNI HC compressor now supports maxDestLen < maxCompressedLength. (Adrien Grand)

  • #12 Fixed ArrayIndexOutOfBoundsException in the Java HC compressors on highly compressible inputs when srcOff is > 0. (Brian S. O'Neill, @foresteve, Adrien Grand)

  • Decompressors have been renamed to "safe" and "fast" to reflect changes in the C API. (Adrien Grand)

  • #18 Added utility methods that take and return (de)compressed byte[]s. (Adrien Grand)

1.1.2

  • LZ4BlockInputStream does not support mark/reset anymore. (Adrien Grand)

  • LZ4BlockOutputStream supports a new syncFlush parameter to configure whether the flush method should flush pending data or just flush the underlying stream. (Adrien Grand)

  • #14 Fixed misspelled API. (Brian S. O'Neill)

1.1.1

  • #11 Fixed bug in LZ4BlockOutputStream.write(int). (Adrien Grand, Brian Moore)

1.1.0

  • lz4 r88

  • #7 LZ4Factory.fastestInstance() only tries to use the native bindings if:

    • they have already been loaded by the current class loader,
    • or if the current class loader is the system class loader. (Adrien Grand)

  • #5 The native instances unpack a shared library to the temporary directory when they are first used. lz4-java now tries to remove this file on exist but this might fail on systems that don't support removal of open files such as Windows. (Adrien Grand)
