Fix test mode to not always return success.
Don't ask for permission to overwrite `nulmark`.

Before:

    > echo "hello world" > file
    > lz4 -t file
    successfully decoded 12 bytes
    > lz4 -tf file
    successfully decoded 12 bytes
    > lz4 file null
    Warning : /dev/null already exists
    Overwrite ? (Y/n) : n
    Error 12 : No. Operation aborted : /dev/null already exists
    > lz4 file /dev/null
    Warning : /dev/null already exists
    Overwrite ? (Y/n) : n
    Error 12 : No. Operation aborted : /dev/null already exists

After:

    > lz4 -t file
    Error 44 : Unrecognized header : file cannot be decoded
    > lz4 -tf file
    Error 44 : Unrecognized header : file cannot be decoded
    > lz4 file null
    Compressed 12 bytes into 31 bytes ==> 258.33%
    > lz4 file /dev/null

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

69dc85b8ab Large decompression speed improvement for GCC 32-bits. Thanks to Valery Croizier ! 
LZ4HC : Compression Level is now a programmable parameter (CLI from 4 to 9)
Separated IO routines from command line (lz4io.c)
Version number into lz4.h (suggested by Francesc Alted)
