Yann ColletandYann Collet ac05ea89a5 fullbench: switch default generator to lorem ipsum 
which creates more "realistic" scenarios than former compressible noise.

The legacy data generator remains accessible,
it is triggered when requesting an explicit compressibility factor (-P#).

Yann Collet 09964c6276 prepare fullbench for a refactor 2024-12-20 10:36:58 -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.

Yann Collet 14a21e43b3 produced ZSTD_compressSequencesAndLiterals() as a separate pipeline

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

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.

Yann Collet 0165eeb441 created ZSTD_entropyCompressSeqStore_wExtLitBuffer()

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.

Diego Nieto Cid 4a4786bef0 tests: fix non-regular file test on GNU/Hurd 
Since commit b21b03ca6 [1] the behaviour of writes to /dev/zero has been
fixed and now the non-regular file removal test no longer needs to be
done on /dev/random (which no longer works as random is not writable now).

Victor Zhang e190e7944e Update cmake minimum requirement to 3.10 
CMake warns on the current minimum requirement (3.5). Update to 3.10.
This means support is still available for the default on Ubuntu 18.04, which
exited LTS standard in April of 2023.
