* lz4.h: clarify the risks of using LZ4_decompress_fast()Alexey Tourbin2018-04-221-5/+7
| | | | | | | | | | | | | | The notes about "security guarantee" and "malicious inputs" seemed a bit non-technical to me, so I took the liberty to tone them down and instead describe the actual risks in technical terms. Namely, the function never writes past the end of the output buffer, so a direct hostile takeover (resulting in arbitrary code execution soon after the return from the function) is not possible. However, the application can crash because of reads from unmapped pages. I also took the liberty to describe what I believe is the only sensible usage scenario for the function: "This function is only usable if the originalSize of uncompressed data is known in advance," etc.

* Ensure LZ4_DEPRECATED("...") is before LZ4LIB_APIAsger Hautop Drewsen2018-01-311-14/+14
| | | | | | When using clang++ with std c++14 or c++17 you would get the error "an attribute list cannot appear here" when including "lz4.h" as the visibility attribute is before the c++ attribute. This ensures that the [[deprecated]] c++ attribute is before everything else in the function declarations.

| | | | | Clang doesn't accept a C++11 attribute following `LZ4LIB_API`. Use the GNU attribute instead.
* dictionary compression correctly uses compression levelYann Collet2017-08-101-18/+18
| | | | Not obvious : copying the state was copying cdict's compression level
* implemented dictionary compression in lz4frameYann Collet2017-08-091-1/+1
| | | | | note : only compression API is implemented and tested still to do : decompression API
* bumped version number to 1.8.0Yann Collet2017-05-101-2/+2

* LZ4_compress_HC_destSize() uses LZ4HC_compress_generic() code pathYann Collet2017-03-161-1/+1

* Export deprecated symbolsDmitry V. Levin2017-03-101-12/+12
| | | | | Deprecated symbols are still a part of ABI and have to be exported, so mark them with LZ4LIB_API attribute.
* Explicitly set visibility of public API functions when gcc is usedDmitry V. Levin2017-03-101-0/+4
| | | | | | | | | | Windows builds already limit exporting of functions to those marked with LZ4LIB_API tag. The same behaviour could be achieved on other platforms when a relatively fresh gcc is used. This change assigns public visibility to all symbols marked with LZ4LIB_API tag. When the library is built in -fvisibility=hidden mode, only these marked symbols will be exported.
