v1.3.3
|
||||
perf: faster zstd_opt strategy (levels 17-19)
|
||||
fix : bug #944 : multithreading with shared ditionary and large data, reported by @gsliepen
|
||||
cli : fix : content size written in header by default
|
||||
cli : fix : improved LZ4 format support, by @felixhandte
|
||||
cli : new : hidden command `-S`, to benchmark multiple files while generating one result per file
|
||||
api : fix : support large skippable frames, by @terrelln
|
||||
api : fix : streaming interface was adding a useless 3-bytes null block to small frames
|
||||
api : change : when setting `pledgedSrcSize`, use `ZSTD_CONTENTSIZE_UNKNOWN` macro value to mean "unknown"
|
||||
build: fix : compilation under rhel6 and centos6, reported by @pixelb
|
||||
build: added `check` target
|
||||
|
||||
v1.3.2
|
||||
new : long range mode, using --long command, by Stella Lau (@stellamplau)
|
||||
new : ability to generate and decode magicless frames (#591)

- Compression parameters cannot be changed once compression is started.
|
||||
- outpot->pos must be <= dstCapacity, input->pos must be <= srcSize
|
||||
- outpot->pos and input->pos will be updated. They are guaranteed to remain below their respective limit.
|
||||
- @return provides the minimum amount of data still to flush from internal buffers
|
||||
- In single-thread mode (default), function is blocking : it completed its job before returning to caller.
|
||||
- In multi-thread mode, function is non-blocking : it just acquires a copy of input, and distribute job to internal worker threads,
|
||||
and then immediately returns, just indicating that there is some data remaining to be flushed.
|
||||
The function nonetheless guarantees forward progress : it will return only after it reads or write at least 1+ byte.
|
||||
- Exception : in multi-threading mode, if the first call requests a ZSTD_e_end directive, it is blocking : it will complete compression before giving back control to caller.
|
||||
- @return provides the minimum amount of data remaining to be flushed from internal buffers
|
||||
or an error code, which can be tested using ZSTD_isError().
|
||||
if @return != 0, flush is not fully completed, there is some data left within internal buffers.
|
||||
- after a ZSTD_e_end directive, if internal buffer is not fully flushed,
|
||||
if @return != 0, flush is not fully completed, there is still some data left within internal buffers.
|
||||
This is useful to determine if a ZSTD_e_flush or ZSTD_e_end directive is completed.
|
||||
- after a ZSTD_e_end directive, if internal buffer is not fully flushed (@return != 0),
|
||||
only ZSTD_e_end or ZSTD_e_flush operations are allowed.
|
||||
It is necessary to fully flush internal buffers
|
||||
before starting a new compression job, or changing compression parameters.
