52a1d1c6dc added ZSTD_DCtx_reset() 2017-09-25 16:56:48 -07:00

f2a913862c added ZSTD_decompress_generic_simpleArgs() 2017-09-25 15:46:34 -07:00
Yann Collet
6ee05a02b8 added ZSTD_decompress_generic() 
same as ZSTD_decompressStream(),
just for a similar feeling as the compression side, which uses ZSTD_compress_generic()

b8d4a3887f introduced constant ZSTD_frameIdSize 
within zstd_internal.h
This is the size of magic number.

Avoids using `4` directly in source code, which is a bit less meaningful.

96f0cde31a minor function rename 
ZSTD_estimateCStreamSize_advanced_usingCParams -> ZSTD_estimateCStreamSize_usingCParams
_usingX is clear.
_advanced feels redundant

cd3115b284 added control from frame content size at end of decompression 
adding check at end of single-pass ZSTD_decompressFrame().
Check within ZSTD_decompressContinue() was already added in a previous patch : b3f33ccfb3

18442a31ff [libzstd] Fix bad window size assert 
The window size is not validated or used in the one-pass API, so there
shouldn't be an assert based on it.

3306bcb0e6 fix #820 : GCC v3.x 32-bits doesn't define 64-bits intrinsic 
resulting in undefined symbol error.
Push the requirement to GCC 4 for now.
Another solution, proposed by @NWilson, is to use __LONG_MAX__ instead.
__LONG_MAX__ is a GCC-specific constant, which value is supposed to depend on underlying target hardware (32/64 bits)
Might be better, but seems also more complex, hence more prone to side effects.
Keeping the simple solution for now (just rely on __GNUC__)

b3f33ccfb3 use ZSTD_decodingBufferSize_min() inside ZSTD_decompressStream() 
Use same definition as public one
minor : reduce allocated buffer size in some cases
(when frameContentSize is known and == windowSize)
 2017-09-09 14:37:28 -07:00
Yann Collet
058ed2ad33 ZSTD_decodingBufferSize_min() 
supporting function for bufferless streaming API (ZSTD_decompressContinue())
makes it possible to correctly size a round buffer for decoding using this API.

also : added field blockSizeMax within ZSTD_frameHeader,
as it's a necessary information to know when to restart at beginning of decoding buffer.
