6ced8f7c7c joined normal streaming API with advanced one 2018-12-03 14:22:38 -08:00
Yann Collet
d8e215cbee created ZSTD_compress2() and ZSTD_compressStream2() 
ZSTD_compress_generic() is renamed ZSTD_compressStream2().

Note that, for the time being,
the "stable" API and advanced one use different parameter planes :
setting parameters using the advanced API does not influence ZSTD_compressStream()
and using ZSTD_initCStream() does not influence parameters for ZSTD_compressStream2().

d4d4e109e9 getParameter fills an int* 
rather than an unsigned*
for consistency
since type of setParameter() changed to int.

7b0391e37e finalized retrofit of ZSTD_CCtx_reset() 
updated all depending sources
 2018-11-14 13:05:35 -08:00

ff8d371708 modified ZSTD_CCtx_reset() 
which now accepts an enum,
to distinguish between resetting the session, or the parameters (or both).

removed ZSTD_CCtx_resetParameters(), which is redundant.

start replacing invocation of ZSTD_CCtx_reset*() functions

Updated advanced API documentation

trimmed down amount of API staged in RC,
in particular, all functions related to ZSTD_CCtxParams()
seem too advanced.

b83d1e7714 removed some static const variables 
and replaced by traditional macro constants.

Unfortunately, C doesn't consider `static const` to mean "constant"

7b74405150 refactor HUF_compress_internal for clarity 
changed workspace parameter convention
to always provide workspaceSize,
so that size can be explicitly checked.

Also, use more enum to make the meaning of some parameters more explicit.

Merge pull request #1317 from felixhandte/split-logs 
Independent Dictionary and Working Context Table Logs
 2018-10-01 17:20:12 -07:00
W. Felix Handte
5b296869df Revert Ability to Set HashLog and ChainLog on Context When Dict is Attached 
This capability is not needed / used in the current unit of work. I'll
re-introduce it later, when we start allowing users to override the deduced
working context logs.
