7f2f1fcd55 Added support for continuation of file compression and decompression if input files are missing. Should more closely match gzip/bzip2/xz and so forth. Also removed a debug print accidentally left in. 2015-04-12 18:41:55 -05:00

0169502b49 Added new LZ4IO_decompressMultipleFilenames to allow decompression of multiple files with the -m switch added in r128 (ref: google code issue 151). Limitation: will only process files matching LZ4_EXTENSION macro, which for now seems reasonable. 2015-04-12 17:33:40 -05:00

97679fa5a1 Google Code Issue 155: lz4 cli should support sparse file 
https://code.google.com/p/lz4/issues/detail?id=155

This is experimental implementation. Just a proof of concept.
It works Linux and Windows.

# Build

To build experimental version, define 'LZ4IO_ENABLE_SPARSE_FILE' like the following command :

    make lz4programs 'CFLAGS=-O3 -DLZ4IO_ENABLE_SPARSE_FILE=1'
    ./programs/lz4 -h

You will see "EXPERIMENTAL_SPARSE_FILE" as lz4 revision :

    "*** LZ4 command line interface 64-bits EXPERIMENTAL_SPARSE_FILE, by Yann Collet (...) ***"

# Experiment

This experimental version adds option "-x" for sparse file for decompression.
You can use this option like this :

    ./programs/lz4 -9 -f my-file
    ./programs/lz4 -d -f -x my-file.lz4 my-file.lz4.out
    cmp my-file my-file.lz4.out

fa27d236b4 Added support for multiple input files to act more like other compressors. For example: gzip file1 file2 file3. You can now do: lz4 [args] -m file1 file2 file3. Fixes 151. 2015-03-01 19:00:40 -06:00
