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.
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.
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.
keep one in compress_frameChunk(),
so that it's tested at every loop
in case some user simply some large mulit-GB input in a single invocation.
Add one in ZSTD_compressBlock(),
since compressBlock() explicitly skips frameChunk().
experimental function ZSTD_compressBlock() is designed for very small data in mind,
for situation where saving the ~12 bytes of frame header can actually make a difference.
Some systems though may have to deal with small and large data entangled.
If it's larger than a block (> 128KB), compressBlock() cannot compress them in one round.
That's why it's possible to compress in multiple rounds.
This is a chain of compressed blocks.
Some users push this capability to the limit, encoding gigantic chain of blocks.
On crossing the 4GB limit, some internal overflow occurs.
This fix moves the overflow correction mechanism higher in the call chain,
so that it's applied also to gigantic chains of blocks.
Added a test case in fuzzer.c, which crashes before the fix, and pass now.
which can be probed using new function ZSTD_minCLevel().
Also : redefined ZSTD_TARGETLENGTH_MIN/MAX for consistency
used the opportunity to bump version number to v1.3.6
