Remove ZSTD_DLL_EXPORT=1 for static lib

f547dca9e3 Remove ZSTD_DLL_EXPORT=1 for static lib
As a principle, static libs should not dllexport methods, that should only be used when building DLLs.

Case in point: when static libs with dllexport directives are linked into DLLs created with a .def file, the VC++ compiler exports the dllexported methods into the DLL, in addition to the exports listed in the .def file. This will result in undesired link dependencies and is not the correct thing to do.

176a543dde In VS2010+, turn off assembler output for libzstd & libzstd-dll, and don't export functions from libzstd 2019-06-07 17:21:51 -06:00

2b4914082e created zstd_decompress_block module
isolate all logic associated with block decompression
into its own module.

zstd_decompress is still in charge
of context creation/destruction,
frames, headers, streaming, special blocks, etc.

Compressed blocks themselves are now handled within zstd_decompress_block .

b2939163e1 Changed default legacy support to v0.5+
thus dropping read support for v0.4.

It's always possible to re-enable it, by changing build macro ZSTD_LEGACY_SUPPORT to 4.

9d6ed9def3 Merge fastCover into DictBuilder (#1274)
* Minor fix

* Run non-optimize FASTCOVER 5 times in benchmark

* Merge fastCover into dictBuilder

* Fix mixed declaration issue

* Add fastcover to symbol.c

* Add fastCover.c and cover.h to build

* Change fastCover.c to fastcover.c

* Update benchmark to run FASTCOVER in dictBuilder

* Undo spliting fastcover_param into cover_param and f

* Remove convert param functions

* Assign f to parameter

* Add zdict.h to Makefile in lib

* Add cover.h to BUCK

* Cast 1 to U64 before shifting

* Remove trimming of zero freq head and tail in selectSegment and rebenchmark

* Remove f as a separate parameter of tryParam

* Read 8 bytes when d is 6

* Add trimming off zero frequency head and tail

* Use best functions from COVER and remove trimming part(which leads to worse compression ratio after previous bugs were fixed)

* Add finalize= argument to FASTCOVER to specify percentage of training samples passed to ZDICT_finalizeDictionary

* Change nbDmer to always read 8 bytes even when d=6

* Add skip=# argument to allow skipping dmers in computeFrequency in FASTCOVER

* Update comments and benchmarking result

* Change default method of ZDICT_trainFromBuffer to ZDICT_optimizeTrainFromBuffer_fastCover

* Add dictType enum and fix bug about passing zParam when converting to coverParam

* Combine finalize and skip into a single parameter

* Update acceleration parameters and benchmark on 3 sample sets

* Change default splitPoint of FASTCOVER to 0.75 and benchmark first 3 sample sets

* Initialize variables outside of for loop in benchmark.c

* Update benchmark result for hg-manifest

* Remove cover.h from install-includes

* Add explanation of f

* Set default compression level for trainFromBuffer to 3

* Add assertion of fastCoverParams in DiB_trainFromFiles

* Add checkTotalCompressedSize function + some minor fixes

* Add test for multithreading fastCovr

* Initialize segmentFreqs in every FASTCOVER_selectSegment and move mutex_unnlock to end of COVER_best_finish

* Free segmentFreqs

* Initialize segmentFreqs before calling FASTCOVER_buildDictionary instead of in FASTCOVER_selectSegment

* Add FASTCOVER_MEMMULT

* Minor fix

* Update benchmarking result
