Yann Collet a0ba849fe6 changed frameContentSize field to pledgedSrcSizePlusOne 
pledgedSrcSize is proper : it's a promise, not yet fulfilled.
It will be controlled at the end.

PlusOne is meant to have 0 (default) == unknown
 2017-06-16 13:29:17 -07:00
Yann Collet 2cf7755da7 fix : pledgedSrcSize correctly reset to unknown in "continue" mode 2017-06-16 12:34:41 -07:00

Yann Collet f35e2de61c linked newAPI to ZSTDMT 2017-06-05 18:32:48 -07:00
Yann Collet 8c910d2097 updated ZSTDMT streaming API 
ZSTDMT streaming API is now similar
and has same capabilites as single-thread streaming API.
It makes it easier to blend them together.
 2017-06-03 01:15:02 -07:00
Yann Collet 58e8d793e1 made debug definitions common within zstd_internal.h 2017-06-02 18:20:48 -07:00

Yann Collet 33a7e679e5 significant zlib wrapper code refactoring 
code indentation
variable scope and names
constify

Only coding style changes.
The logic should remain the same.
 2017-06-02 17:10:49 -07:00
Yann Collet 4effccbf56 zlib_wrapper's uncompress() uses ZSTD_isFrame() for routing 
more generic and safer than using own routing for magic number comparison
 2017-06-02 14:27:11 -07:00
Yann Collet dcb7535352 ensure zlibwrapper uses ZSTD_malloc() and ZSTD_free() 
which is compatible with { NULL, NULL, NULL }
 2017-06-02 14:01:21 -07:00
Yann Collet b877e834b1 minor indent 2017-06-02 13:47:11 -07:00

Yann Collet c35e535002 added support for multithreading parameters 2017-06-01 18:44:06 -07:00
Yann Collet c4a5a21c5c created ZSTDMT_sizeof_CCtx() and POOL_sizeof() 
required by ZSTD_sizeofCCtx() while adding a ZSTDMT_CCtx*
 2017-06-01 17:56:14 -07:00
Yann Collet cd2892fd1e protected impossible switch(){default:} with assert(0) 
can be converted into assume(0) in some future
 2017-06-01 09:44:54 -07:00
Yann Collet 06589fe516 Merge branch 'advancedAPI2' of github.com:facebook/zstd into advancedAPI2 2017-05-31 10:03:20 -07:00
Yann Collet 18ab5affa5 fixed visual warning 2017-05-31 09:59:22 -07:00
Yann Collet 01b1549f83 finally converted ZSTD_compressStream_generic() to use {in,ou}Buffer 
replacing the older read/write variables from ZBUFF_* era.
Mostly to help code readability.

Fixed relevant callers.
 2017-05-30 18:10:26 -07:00
Yann Collet c4f46b94ce ZSTD_createCCtx_advanced() now uses ZSTD_calloc() 
initially uses calloc() instead of memset().

Performance improvement is unlikely measurable,
since ZSTD_CCtx is now very small,
with all tables transferred into workSpace.
 2017-05-30 17:45:37 -07:00
Yann Collet deee6e523f expose ZSTD_compress_generic_simpleArgs() 
which is a binding towards ZSTD_compress_generic()
using only integral types for arguments.
 2017-05-30 17:42:00 -07:00
Yann Collet ae728a43b8 removed defaultCustomMem 
now ZSTD_customCMem is promoted as new default.

Advantages : ZSTD_customCMem = { NULL, NULL, NULL},
so it's natural default after a memset.

ZSTD_customCMem is public constant
(defaultCustomMem was private only).

Also : makes it possible to introduce ZSTD_calloc(),
which can now default to stdlib's calloc()
when it detects system default.

Fixed zlibwrapper which depended on defaultCustomMem.
 2017-05-30 17:11:39 -07:00
Yann Collet 5bcef1ada2 removed mtctx->cstream 
use the first cctx in pool when ZSTDMT is used in single-thread mode
now that cctx and cstream are the same object.
 2017-05-30 16:37:19 -07:00
Yann Collet beb62b15a8 Merge branch 'dev' into advancedAPI2 
Fixed conflic in zstd_decompress.c
 2017-05-30 16:18:57 -07:00
Yann Collet 44e45e8423 added ZSTDMT_createCCtx_advanced() 
make it possible to use custom allocators
 2017-05-30 16:12:06 -07:00
Yann Collet f45ca527a1 Merge branch 'advancedAPI2' of github.com:facebook/zstd into advancedAPI2 2017-05-30 10:02:03 -07:00
Yann Collet 7028cbd7fd fixed a few code comments : ZSTD_getFrameParams => ZSTD_getFrameHeader 2017-05-25 18:29:08 -07:00
Yann Collet cdf7e82222 Added ZSTD_initStaticCDict() 2017-05-25 18:05:49 -07:00
Yann Collet 57827f906f added ZSTD_initStaticDDict() 2017-05-25 15:44:06 -07:00
Yann Collet 25989e361c updated ZSTD_estimate?DictSize() to pass parameter byReference 
resulting ?Dict object is smaller when created byReference.
Seems better than a documentation note.
 2017-05-25 15:07:37 -07:00
Yann Collet 0fdc71c3dc added ZSTD_initStaticDCtx() 2017-05-24 17:41:41 -07:00
Yann Collet ba183005d3 merged DStream's inBuff and outBuff into a single buffer 
Saves one malloc().
Also : makes it easier to implement static allocation
 2017-05-24 15:42:24 -07:00
Yann Collet 2e4db3e531 fixed performance regression with ZSTD_decompress() on small files 
memset() was a quick fix to initialization problems,
but initialize too much space (tables, buffers)
which show up in decompression speed of ZSTD_decompress()
since it needs to recreate DCtx at each invocation.

Fixed by only initialization relevant pointers and size fields.
 2017-05-24 13:15:19 -07:00
Yann Collet 11ea2f7fda Merged ZSTD_DCtx and ZSTD_DStream objects 
They are now the same object.
It's recommended to keep both types in source code
as previous versions of library (<v1.3.0)
still need this differentiation.
 2017-05-23 16:19:43 -07:00
Yann Collet b81f19ffce move MEM_readMINMATCH() into zstd_opt.h 
which is its only user.
Use case too narrow to belong to mem.h.
renamed to ZSTD_readMINMATCH()
 2017-05-23 15:41:55 -07:00
Yann Collet c7fe262dc9 added ZSTD_initStaticCCtx() 
makes it possible to statically or externally allocate CCtx.
static CCtx will only use provided memory area,
it will never resize nor malloc.
 2017-05-23 13:20:41 -07:00
Yann Collet 5ac72b417c Buffered are now allocated inside workSpace 2017-05-23 11:18:24 -07:00
Yann Collet 1880337c30 Simplifier compression call graph 
Everything converge towards ZSTD_compressBegin_internal
which delegated to ZSTD_copyCCtx_internal if cdict!=NULL.

This simplifies routing which was previously depending on cdict.
 2017-05-22 18:21:51 -07:00
Yann Collet b0739bcf8f simplified reset by removing full-reset policy 
this was meant to be applied prior to dictionary loading.
But effectively, it seems redundant with later loading stage,
so it can be skipped safely.
 2017-05-22 17:45:15 -07:00
Yann Collet 1ad7c82eb5 Implemented separation between requested and applied parameters 
first version to pass cli tests with -DZSTD_NEWAPI
 2017-05-22 17:06:04 -07:00
Yann Collet 24de7b0346 Implemented ZSTD_CCtx_refCDict() 2017-05-22 13:05:45 -07:00
Yann Collet ee970398b2 Merge branch 'dev' into advancedAPI2 2017-05-22 12:33:56 -07:00
Yann Collet 8b21ec42a9 ZSTD_compress_generic() can handle dictionary compression 2017-05-19 19:46:15 -07:00
Yann Collet 60a557e7fd fixing symbol.c test 
I believe it would be better to rely on fuzzer tests compiled with dll
 2017-05-19 11:27:43 -07:00
Yann Collet 334a288d0d ZSTD_CCtx_setParameter() only works during initialization stage 
and generate a stage_wrong error otherwise.
 2017-05-19 11:04:41 -07:00
Yann Collet 48855fa0d2 fixed declaration-after-statement warning 2017-05-19 10:56:11 -07:00
Yann Collet fa3671eac7 changed ZSTD_BLOCKSIZE_ABSOLUTEMAX into ZSTD_BLOCKSIZE_MAX 
Also :
change ZSTD_getBlockSizeMax() into ZSTD_getBlockSize()
created ZSTD_BLOCKSIZELOG_MAX
 2017-05-19 10:51:30 -07:00
Yann Collet 009d604e00 ZSTD_compress_generic() supports multiple successive frames 
also : clarified streaming API implementation
 2017-05-19 10:17:59 -07:00
Yann Collet 6d4fef36de Added ZSTD_compress_generic() 
Used in fileio.c (zstd cli).
Need to set macro ZSTD_NEWAPI to trigger it.
 2017-05-17 18:36:15 -07:00
Yann Collet 23c256e44b removed useless variable from CCtx 
CStream's pledgedSrcSize is no longer necessary
srcSize control is realized within bufferless interface.
 2017-05-16 18:10:11 -07:00
Yann Collet 906a8f269a Merge branch 'dev' into advancedAPI2 2017-05-16 17:33:08 -07:00
Yann Collet e12ae02357 minor coding style update 
reduced some long lines
 2017-05-16 17:32:33 -07:00
Yann Collet 9f95e445ab minor comment clarifications 2017-05-16 17:26:43 -07:00
Yann Collet 0bdb575c31 Merge branch 'dev' into advancedAPI2 2017-05-16 16:32:29 -07:00
Yann Collet 7101434ec9 pedantic : added one error check 
on a function which (today) never fails.
But who knows, maybe tomorrow ...
 2017-05-16 16:28:24 -07:00
Yann Collet bfff8999c5 added prototype ZSTD_versionString() 2017-05-16 16:12:23 -07:00
Yann Collet 4eff8136aa added prototype ZSTD_decompressBegin_usingDDict (#700) 2017-05-16 16:05:27 -07:00
Yann Collet 2d4d31c18a removed gcc compilation flag -Wbad-function-cast 
It makes it more difficult to directly cast the result of a function,
requiring to store the result in an intermediate variable.
It does not necessarily help readability,
and this restriction can be difficult to overcome in some constructions,
like some macros.

also : fixed minor Visual conversion warnings in datagencli.c
 2017-05-16 11:34:38 -07:00
Yann Collet 46ac9ade9b fixed vla warning on linux 2017-05-15 18:15:08 -07:00
Yann Collet 133f0aee54 fixed redundant declarations in legacy v0.5 and v0.7 decoders 
triggered by new flag -Wredundant-decls
 2017-05-15 17:44:04 -07:00
Yann Collet 83d0c764dc added several compilation flags 2017-05-15 17:15:46 -07:00
Yann Collet a5ffe3d370 pushed enum values for strategy by one (ZSTD_fast==1) 
this makes it possible to use `0` to mean:
"do not change strategy"
 2017-05-12 16:29:19 -07:00
Yann Collet add66f816d changed macro LOADCPARAMS by static function ZSTD_cLevelToCParams() 
for improved compiler checks.
Also : ensure most parameters can receive value "0"
to mean "do not change".
 2017-05-12 16:01:15 -07:00
Yann Collet b0edb7fb0e added ZSTD_CCtx_setParameter() 2017-05-12 15:31:53 -07:00
Yann Collet ef738c1b23 better error code when compressing using NULL CDict 
which is not allowed (but detected, and generates an error).
 2017-05-12 13:55:25 -07:00
Yann Collet db8e21d5a0 made ZSTD_compress_generic() definition accessible 
note that the implementation is not done yet.
 2017-05-12 13:46:49 -07:00
Yann Collet 33eb7ac6b6 updated Advanced API proposal 
only declarations in zstd.h
 2017-05-12 12:36:11 -07:00
