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.

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 }

Yann Collet 9a691e0f55 fixed visual warnings 2017-05-31 01:17:44 -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

to make ZSTDMT_CCtx_s size predictable
so that it can be included in CCtx
2017-05-27 00:21:33 -07:00
Yann Collet b8136f019a static dctx is incompatible with legacy support
documented, and runtime tested
2017-05-27 00:03:08 -07:00

Yann Collet cdf7e82222 Added ZSTD_initStaticCDict() 2017-05-25 18:05:49 -07:00
Dmitry V. Levin 1ea655c765 Fix typo in libzstd.a-mt make rules
The macro name is ZSTD_MULTITHREAD, not ZSTD_MULTHREAD.

Fixes: ca6fae7808 ("Add MT enabled targets for libzstd")
2017-05-25 23:43:05 +00:00
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

Nick Terrell 55fc1f91fd [zstd] Fix up formatting edge cases for clang-format 2017-05-24 13:50:10 -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.

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

and generate a stage_wrong error otherwise.

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.
