Nick Terrell 9009b59f09 [linux-kernel] Add missing semicolon in zstd_deps.h 2020-09-23 23:26:10 -07:00
Nick Terrell 9261476b7d [lib] Wrap customMem xor checks in parens for readability 
This clarifies operator precedence, and quiets cppcheck in
the Kernel Test Robot. I think this is a slight bonus to
readability, so I am accepting the suggestion.

W. Felix Handte 8930c6e551 Use ZSTD_CCtxParams_init() to Init CCtxParams, not memset() 
Even if the discrepancies are at the moment benign, it's probably better to
standardize on using the one true initializer, rather than trying (and failing)
to correctly duplicate its behavior.

W. Felix Handte eee51a664a Fall Back if Derived CParams are Incompatible with DDSS; Refactor CDict Creation 
Rewrite ZSTD_createCDict_advanced() as a wrapper around
ZSTD_createCDict_advanced2(). Evaluate whether to use DDSS mode *after* fully
resolving cparams. If not, fall back.

DDSS for Lazy: Implement a Dedicated Dictionary Chain Table
 2020-09-11 01:39:23 -04:00
W. Felix Handte d6246d4a0f Print More During Fuzzer Test to Avoid CI Killing it Due to Timeout 
This is kind of hacky. And maybe this test doesn't need to be permanently as
exhaustive as it is now. But while we're actively developing the DDSS, we
should ensure it's compatible across many different modes.

W. Felix Handte 06d240b8a7 Use All Available Space in the Hash Table to Extent Chain Table Reach 
Rather than restrict our temp chain table to 2 ** chainLog entries, this
commit uses all available space to reach further back to gather longer
chains to pack into the DDSS chain table.

W. Felix Handte 9b9feb84f2 Lay Out Chain Table Chains Contiguously 
Rather than interleave all of the chain table entries, tying each entry's
position to the corresponding position in the input, this commit changes the
layout so that all the entries in a single chain are laid out next to each
other. The last entry in the hash table's bucket for this hash is now a packed
pointer of position + length of this chain.

This cannot be merged as written, since it allocates temporary memory inside
ZSTD_dedicatedDictSearch_lazy_loadDictionary().
