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

542c9dfcf8 changed name frameParams into frameHeader 
ZSTD_frameParams => ZSTD_frameHeader
ZSTD_getFrameParams() -> ZSTD_getFrameHeader()

The new naming is more distinctive from ZSTD_frameParameters,
which is used during compression.

ZSTD_frameHeader is clearer in its intention to described frame header content.
It also implies we are decoding a ZSTD frame, hence we are at decoding stage.

fc5145955a updated ZSTD_estimateCCtxSize() 
added a parameter streaming,
to estimate memory allocation size
when the CCtx is used for streaming (CStream).

Note : this function is not able to estimate
memory cost of a potential internal CDict
which can only happen when starting with ZSTD_initCStream_usingDict()

f4bd857d81 created ZSTD_compress_usingCDict_advanced() 2017-04-27 11:31:55 -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.

 2017-04-18 22:52:41 -07:00
Yann Collet
0bb381dad8 added test for ZSTD_initCStream_advanced() 
when params.fParams.contentSizeFlags = 1
and pledgedSrcSize = 0
then srcSize should be considered 0 (empty), and not "unknown"
 2017-04-18 15:08:52 -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.

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

Yann Collet
4b987ad8ce Introduce ZSTD_initCStream_internal() 
This is now the regroup point for ZSTD_initCStream*() functions

ZSTD_initCStream_advanced() now properly checks for parameters validity.

Also : added <assert.h> usage inside zstd_compress.c
Needs ZSTD_DEBUG=1 macro to be triggered.
Will be triggered by default from `tests` directory
