3dcafd35d4 Fix test mode and write to null 
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
    Compressed 12 bytes into 31 bytes ==> 258.33%

c5cb4aa52a Merge pull request #238 from kou/add-lz4lib-api 
Add LZ4LIB_API
 2016-09-23 08:54:24 +02:00
Kouhei Sutou
012c66536c Add LZ4LIB_API 
It's based on Zstandard's ZSTDLIB_API.

See also: https://github.com/Cyan4973/lz4/issues/216#issuecomment-226245432

Deprecated functions aren't LZ4LIB_API targets. Because we don't need to
export deprecated functions from now.

There are same LZ4LIB_API definitions in each header files instead of
including a common header file because LZ4_DEPRECATED is defined so.
 2016-09-23 00:39:45 +09:00
Kouhei Sutou
46a7b94e8c Use lower case for header file name 
"WinIoCtl.h" works on Windows because Windows uses case insensitive file
system. But it doesn't work on GNU/Linux (for cross compiling with
MinGW) because GNU/Linux uses case sensitive file system.

Origin/r129/multiple inputs patch
 2015-04-13 21:03:51 +02:00
Kyle J Harper
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
Kyle J Harper
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

41b6ed3c5b Replace fseek with _fseeki64 to avoid MSVC's 2GiB barrier 
Since MSVC fseek()'s SEEK_CUR mode has 2GiB barrier, our fseek() calling in program/lz4io.c/selectDecoder() will fail for large (>2GiB) .lz4 file.
This commit just replace fseek with _fseeki64 by macro. Second argument is automatically casted to __int64 (signed 64bit integer). Other things are completely same.
