Yann Collet 95ad9e47ff added benchmark for ZSTD_convertBlockSequences_wBlockDelim() 2024-12-20 10:37:00 -08:00
Yann Collet d48e330ae1 change name to ZSTD_convertSequences*() 2024-12-20 10:37:00 -08:00
Yann Collet 31b5ef2539 ZSTD_compressSequencesAndLiterals() now supports multi-blocks frames. 2024-12-20 10:36:59 -08:00
Yann Collet 5164d44dab change advanced parameter name: ZSTD_c_repcodeResolution 
and updated its documentation.
Note: older name ZSTD_c_searchForExternalRepcodes remains supported via #define
 2024-12-20 10:36:59 -08:00
Yann Collet ca8bd83373 minor: cleaner function parameter repcodeResolution 2024-12-20 10:36:59 -08:00
Yann Collet d2d0fdac42 updated documentation on validateSequence 2024-12-20 10:36:59 -08:00
Yann Collet 1f6d6815c3 optimization: instantiate specialized version without Sequence checking code 
results in +4% compression speed,
thanks to removal of branches in the hot loop.
 2024-12-20 10:36:59 -08:00
Yann Collet a288751de7 minor optimization: only track seqPos->posInSrc when validateSequences is enabled 
note: very minor saving, no performance impact
 2024-12-20 10:36:59 -08:00
Yann ColletandYann Collet f176514467 minor doc update 2024-12-20 10:36:59 -08:00
Yann ColletandYann Collet 1c8f5b0f11 minor optimization for ZSTD_compressSequencesAndLiterals() 
does not need to track and update internal `litPtr`.
note: does not measurably impact performance.

Yann ColletandYann Collet 0a5c0807af minor conversion warning fix 2024-12-20 10:36:59 -08:00
Yann ColletandYann Collet f281497aef fullbench: new scenario: compressSequencesAndLiterals() 2024-12-20 10:36:59 -08:00
Yann Collet 8ab04097ed add the compressSequences() benchmark scenario 2024-12-20 10:36:59 -08:00
Yann Collet 0b013b2688 added unit tests to ZSTD_compressSequencesAndLiterals() 
seems to work as expected,
correctly control that `litSize` and `srcSize` are exactly correct.
 2024-12-20 10:36:58 -08:00
Yann Collet 14a21e43b3 produced ZSTD_compressSequencesAndLiterals() as a separate pipeline 
only supports explicit delimiter mode, at least for the time being
 2024-12-20 10:36:58 -08:00
Yann Collet bcb15091aa minor: more accurate variable scope 2024-12-20 10:36:58 -08:00
Yann Collet 047db4f1f8 ZSTD_SequenceCopier_f no returns the nb of bytes consumed from input 
which feels much more natural

Yann Collet 76dd3a98c4 scope: ZSTD_copySequencesToSeqStore*() are private to ZSTD_compress.c 
no need to publish them outside of this unit.

Yann Collet 1ac79ba1b6 minor: simplify ZSTD_selectSequenceCopier 2024-12-20 10:36:56 -08:00
Yann Collet 894ea31281 codemod: ZSTD_sequenceCopier -> ZSTD_SequenceCopier_f 2024-12-20 10:36:56 -08:00
Yann Collet c97522f7fb codemod: ZSTD_sequenceFormat_e -> ZSTD_SequenceFormat_e 
since it's a type name.

Note: in contrast with previous names, this one is on the Public API side.
So there is a #define, so that existing programs using ZSTD_sequenceFormat_e still work.
 2024-12-20 10:36:56 -08:00
Yann Collet 0165eeb441 created ZSTD_entropyCompressSeqStore_wExtLitBuffer() 
can receive externally defined buffer of literals

Yann Collet a2245721ca codemod: seqStore_t -> SeqStore_t 
same idea, SeqStore_t is a type name, it should start with a Capital letter.
 2024-12-20 10:36:55 -08:00
Yann Collet 9671813375 codemod: seqDef -> SeqDef 
SeqDef is a type name, so it should start with a Capital letter.
It's an internal symbol, no impact on public API.
 2024-12-20 10:36:55 -08:00
Yann Collet b4a40a845f move Sequences definition to zstd_compress_internal.h 
they should not be in common/zstd_internal.h,
since these definitions are not shared beyond lib/compress/.
 2024-12-20 10:36:55 -08:00
Yann Collet a00f45a037 created ZSTD_storeSeqOnly() 
makes it possible to register a sequence without copying its literals.

Yann Collet 50ca9984ad minor: more accurate parameter 
just pass ldm_bucketLog, instead of the entire ldm* state
 2024-12-14 11:57:14 -08:00
郑苏波 (Super Zheng)andNick Terrell 5e0a83ec25 Disallow 32-bit mode in clang section
