e68c2d86e7 refactor paramgrill for clarity 
restored ability to copy/paste the resulting compression level table into zstd_compress.c .

39e28982cf introduced constants ZSTD_STRATEGY_MIN and ZSTD_STRATEGY_MAX 2018-12-06 16:16:16 -08:00

be9e561da4 changed ZSTD_c_compressionStrategy into ZSTD_c_strategy 
also : fixed paramgrill, and limit conditions

3583d19c4e changed parameter names from ZSTD_p_* to ZSTD_c_* 
for naming consistency

34e146f548 advanced decompression function replaces by normal streaming one 
advanced parameters compatible with ZSTD_decompressStream().

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().

e874dacc08 changed searchLength into minMatch 
refactored all relevant API and calls
for consistency.

5c68639186 updated ZSTD_DCtx_reset()

b830ccca5c changed benchfn api 
to use structure for function parameters
as it expresses much clearer than a long list of parameters,
since each parameter can now be named.

d38063f8ae separated bench module into benchfn and benchzstd 
it shall be possible to use benchfn
without any dependency on zstd.

efbc3e823d fixed paramgrill wrong assert() conditions 
and slightly refactored affected function.

Honestly, the formula calculating variance should get a second reviewing round,
it's not clear if it's correct.

55affc09de timedFn : measurement delay is programmable 
instead of hard-coded 1 second per measurement

0ff9b67552 paramgrill: removed useless tests 
designed to compensate iter_mode,
but since only time_mode is available now,
all tests are guaranteed to last a minimum amount of time.

9e26893e07 paramgrill: fixed a bunch of div-by-zero 
they were pretty easy to trigger by the way,
just start an extended paramgrill session
to find a compression table based on any sample,
it would necessarily happen at some point.

0071e8348f restored assert() in paramgrill 
assert() in paramgrill are not in the benchmark path.
They should remain active, as they don't impact measurements, and their runtime is insignificant.

4da5bdf482 fixed zstd -b speed result 
the benchmark was displaying the speed of last run
instead of the best of all previous runs.
