Makes frame type (zstd,skippable) detection more straighforward.
ZSTD_getFrameHeader set frameContentSize=ZSTD_CONTENTSIZE_UNKNOWN to mean "field not present"
use less macro statements
the initial version was meant to work with STATIC_ASSERT
but since it doesn't work and needs assert()
it's possible to rewrite it using normally compiled code
which is better for compiler.
Downside : the error message is less precise.
There is a DEBUGLOG(3,) to compensate.
ZSTD_estimateCDictSize() now uses same arguments as ZSTD_createCDict()
ZSTD_estimateCDictSize_advanced() uses same arguments as ZSTD_createCDict_advanced()
ZSTD_estimateCCtx() is now a "simple" function,
taking int compressionLevel as single argument.
ZSTD_estimateCCtx_advanced() takes a CParams argument,
which is both more complete and more complex to generate.
Doesn't speed optimize this buffer-to-buffer scenario yet.
Still internally defers to streaming implementation.
Also : fixed a long standing bug in ZSTDMT streaming API.
* upstream/dev: (305 commits)
added test for ZSTD_estimateCStreamSize()
changed variable name, for clarity
fixed ZSTD_estimateCStreamSize()
shortened ZSTD_createCStream_Advanced()
fixed symbols test
added ZSTD_estimateDStreamSize()
changed name frameParams into frameHeader
regroup memory usage function declarations
separated ZSTD_estimateCStreamSize() from ZSTD_estimateCCtxSize()
bumped version number
added ZSTD_estimateCDictSize() and ZSTD_estimateDDictSize()
Updated ZSTD_freeCCtx()
updated ZSTD_estimateCCtxSize()
Updated ZSTD_sizeof_CCtx()
merged CCtx and CStream as a single same object
cli : -d and -t do not stop after a failed decompression
added dev branch CircleCI badge
added dev branch Appveyor badge
keep dev branch status only
creates a binary archive without the `programs` directory
...
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.
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()
