87406548f0 reduced DDict size, by -2KB 
corresponding to the removal of workspace
which is needed while building huffman table
and is now either present in DCtx,
or temporarily borrowed from available FSE table space.

[zstd] Fix seqStore growth
 2018-08-28 17:10:25 -07:00
Yann Collet
0c66a44d1b first working test program 
measures :
- compression ratio with / without dictionary
- create one dictionary per block
- memory budget for dictionaries
- decompression speed, using one different dictionary per block

current limitations :
- only one file
- 4K blocks only
- automatic dictionary built with 4K size

dictionary can be selected on command line, with -D

5e580de6da [zstd] Fix seqStore growth 
We could undersize the literals buffer by up to 11 bytes,
due to a combination of 2 bugs:
* The literals buffer didn't have `WILDCOPY_OVERLENGTH` extra
  space, like it is supposed to.
* We didn't check the literals buffer size in `ZSTD_sufficientBuff()`.

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.
