Yann Collet a00e9599f1 removed -g from DEBUGFLAGS
It inflates binary sizes, which is negative for the Windows build.
It also makes it impossible to check if 2 different source codes
get nonetheless compiled to the same binary,
since checksum will be different, due to integrated source code.

Yann Collet a51cab6e68 Merge pull request #678 from facebook/apiChange
Breaking API Change around CDict
2017-04-28 10:02:45 -07:00
Yann Collet 29297c6751 Changed default level 18 (large input)
Previous -18 : 4.7 MB/s, R:3.833
New -18 : 5.1 MB/s. R:3.825

It's a better fit within -17 (6.8 MB/s) and -19 (4.0 MB/s)
The new level 18 also uses significantly less memory.
And, it makes a good transition between level 17 (mml5)
and level 19 (mml3).
Up to now, there was no level with mml4.

(note : minmatch setting can have a large impact on some (specific) datasets)

Yann Collet 69a54d138a fixed compilation warning : declaration-after-statement 2017-04-27 01:11:26 -07:00
Yann Collet 31533bacce Changed ZSTD_createCDict_advanced()
It now only uses compressionParameters as argument.
It produces many changes throughout user code,
though hopefully they tend to be simple :
just provide the cParams part from existing ZSTD_parameters.

Some programs might depend on ZSTD_createCDict_advanced() to pass frame parameters.
This change will force them to revisit this strategy and fix it,
since frame parameters are effectively silently ignored in current version.
2017-04-27 00:29:04 -07:00
Yann Collet 768df129d2 changed ZSTD_compressBegin_usingCDict()
No longer takes `pledgedSrcSize` as argument
this is in line with similar functions ZSTD_compress_usingCDict()
and ZSTD_initCStream_usingCDict().
2017-04-26 15:42:10 -07:00
Yann Collet e42afbc6fa Comply with suggested comments by @terrelln

still need to be transferred from CCtx into workspace
2017-04-20 22:54:54 -07:00
Yann Collet a34a39c183 changed size evaluation of entropy tables
so that memcpy() does no longer depends on fse pointer being a static table
2017-04-20 18:26:25 -07:00
Yann Collet 7bb60b17d8 init entropy table pointers only once
per workSpace resize
2017-04-20 17:38:56 -07:00
Yann Collet e6fa70a0a1 reorganized ZSTD_resetCCtx_internal()
clearer separation between variables and buffers
clearer buffers category
kept static buffers at the beginning, favoring cache locality
(it will be easier to add FSE tables there later)

This break a few assumptions that hashTable was always at the beginning.
This is fixed.
And remaining assumptions (namely that tables stand next to each other in memory)
are now tested with assert.
2017-04-20 17:28:31 -07:00
Yann Collet c17e020c9a disable assert when compiling paramgrill
paramgrill is a benchmark calibration function.
Speed accuracy is critical, it cannot be altered by assert.

to enforce correct frame parameters

Sean Purcell 98cf7fcb2a Update README 2017-04-18 17:03:37 -07:00

Yann Collet 30fb499208 Changed ZSTD_resetCCtx_advanced() into ZSTD_resetCCtx_internal()
for naming consistency :
_advanced() can be invoked
while _internal() are strictly static

Yann Collet af4f45b682 Improved code comments for block functions 2017-04-18 03:17:44 -07:00
Yann Collet 4f818182b8 clarified frame parameters for ZSTD_compress*_usingCDict()
created ZSTD_compressBegin_usingCDict_internal(),
which gives direct control to frame Parameters.
ZSTD_resetCStream_internal() now points into it.

Yann Collet c47c68f6ca proper evaluation of Huffman CTable size 2017-04-17 16:14:21 -07:00
Yann Collet 88009a8ba2 removed srcSize control from CStream
since it's already done from lower bufferless API level
2017-04-12 00:51:24 -07:00
Yann Collet 20d5e03893 content size is controlled at bufferless level
so it's active for all entry points

Also : added relevant test (wrong content size) in fuzzer
2017-04-11 18:34:02 -07:00
Yann Collet 4ee6b15dac force contentSizeFlag=0 when using ZSTD_initCStream_usingCDict()
because by definition srcSize is not known when using this prototype.
added relevant test

Note : this use was already working, because at a later stage
(both ZSTD_compressBegin_usingCDict() and ZSTD_copyCCtx())
pledgedSrcSize=0 is translated into "unknown", no matter the frame parameter.
This is not correct, but of little importance,
as the medium term plan is to no longer set fParams within CDict
2017-04-11 11:59:44 -07:00
Yann Collet ab9162ebb4 simplified call graph
by calling ZSTD_compressBegin_internal() instead of ZSTD_compressBegin_advanced()
2017-04-11 10:46:20 -07:00
Yann Collet e88034fe26 simplified ZSTD_initCStream*() flow
all variants converge towards ZSTD_initCStream_stage2()
