* changed macro HEAPMODE into LZ4_HEAPMODEYann Collet2017-05-022-13/+14
| | | | | | | This macro is susceptible to be triggered from user side typically through compiler flag (-DLZ4_HEAPMODE=1). In which case, it makes sense to prefix the macro since we want to reduce potential side-effect on namespace.
* lz4hc.c: clamp compression levels > 12Alexey Tourbin2017-04-291-0/+2
| | | | | | | | | | | | | | | I noticed that, while 'lz4 -12' works fine, 'lz4 -13' does not compress at all. $ cat </etc/passwd |wc -c 2565 $ lz4 -12 </etc/passwd |wc -c 1456 $ lz4 -13 </etc/passwd |wc -c 2584 Perhaps the best way to fix this is to clamp the compression level in the LZ4HC_compress_generic routine.

This change does the same with functions declared in lz4hc.h file, thus extending the export to lz4hc.h. As result, the following 17 deprecated functions are exported again: LZ4_compressHC LZ4_compressHC2 LZ4_compressHC2_continue LZ4_compressHC2_limitedOutput LZ4_compressHC2_limitedOutput_continue LZ4_compressHC2_limitedOutput_withStateHC LZ4_compressHC2_withStateHC LZ4_compressHC_continue LZ4_compressHC_limitedOutput LZ4_compressHC_limitedOutput_continue LZ4_compressHC_limitedOutput_withStateHC LZ4_compressHC_withStateHC LZ4_createHC LZ4_freeHC LZ4_resetStreamStateHC LZ4_sizeofStreamStateHC LZ4_slideInputBufferHC

| * 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. Levin2017-03-102-0/+8
| | | | | | | | | | | | | | | | | | | | 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.
