pinned down error code enum values
...
Note : all error codes are changed by this new version,
but it's expected to be the last change for existing codes.
Codes are now grouped by category, and receive a manually attributed value.
The objective is to guarantee that
error code values will not change in the future
when introducing new codes.
Intentionnal empty spaces and ranges are defined
in order to keep room for potential new codes.

policy change : ZSTDMT automatically caps nbThreads to ZSTDMT_NBTHREADS_MAX ( #760 )
...
Previously, ZSTDMT would refuse to create the compressor.
Also : increased ZSTDMT_NBTHREADS_MAX to 256,
updated doc,
and added relevant test
2017-07-13 10:17:23 -07:00

switched ZSTDMT_compress_advanced() last argument to overlapLog
...
overlapRLog (== 9 - overlapLog) was a bit "strange"
as all other public entry points use overlapLog

slightly increased buffer pool, to cover normal "full load" scenarios
...
2 buffers per active worker
+ 1 buffer for input loading
+ 1 buffer for "next input" when submitting current one
+ 1 buffer stuck in queue
2017-07-12 14:23:34 -07:00

fix : ZSTDMT_compress_advanced() correctly generates checksum
...
when params.fParams.checksumFlag==1.
This use case used to be impossible when only ZSTD_compress() was available
2017-07-11 17:18:26 -07:00

release input buffers from inside worker thread
...
buffers are released sooner, which makes them available faster for next job.
=> decreases total nb of buffers necessary

buffer pool : all buffers have same size

to reduce memory fragmentation.
They can be used for in or out, interchangeably.

zstdmt : intermediate outBuffer allocated from within worker

since jobs in queue do not have an outBuffer pre-reserved now
2017-07-11 14:59:10 -07:00

improved ZSTDMT_compress() memory usage
...
does not need the input buffer for streaming operations
also : reduced a few tests time length

optimized memory usage for ZSTDMT_compress()
...
Previously, each job would reserve a CCtx right before being posted.
The CCtx would be "part of the job description",
and only released when the job is completed (aka flushed).
For ZSTDMT_compress(), which creates all jobs first and only join at the end,
that meant one CCtx per job.
The nb of jobs used to be == nb of threads,
but since latest modification,
which reduces the size of jobs in order to spread the load of difficult areas,
it also increases the nb of jobs for large sources / small compression level.
This resulted in many more CCtx being created.
In this new version, CCtx are reserved within the worker thread.
It guaranteea there cannot be more CCtx reserved than workers (<= nb threads).
To do that, it required to make the CCtx Pool multi-threading-safe :
it can now be called from multiple threads in parallel.

fixed wrong assert() condition
...
A single job created by ZSTDMT_compress() can be < 256KB
if data to compress is < 256 KB
(in which case it is delegated to single thread mode)

first implementation of bench.c with new API ZSTD_compress_generic()

Doesn't speed optimize this buffer-to-buffer scenario yet.
Still internally defers to streaming implementation.

ZSTDMT streaming API is now similar
