added a fake initialization to please an analyzer

which is unable to understand that the variable is necessarily initialized

5 years agofix fuzzer tests on dirty context
Yann Collet [Mon, 15 Apr 2019 18:12:54 +0000 (11:12 -0700)]
fix fuzzer tests on dirty context

context is no longer dirty after a failed compressed block.
Actually, all indexes are fine.
It remains compatible with continued streaming, and reset*_fast().

5 years agounified limitedOutput_directive
Yann Collet [Mon, 15 Apr 2019 18:09:56 +0000 (11:09 -0700)]
unified limitedOutput_directive

between lz4.c and lz4hc.c .
was left in a strange state after the "amalgamation" patch.

Now only 3 directives remain,
same name across both implementations,
single definition place.

Might allow some light simplification due to reduced nb of states possible.

5 years agodecompress*_fast() function do not generate deprecation warnings
Yann Collet [Mon, 15 Apr 2019 17:33:40 +0000 (10:33 -0700)]
decompress*_fast() function do not generate deprecation warnings

they are classified as deprecated in the API documentation (lz4.h)
but do not yet trigger a warning,
to give time to existing applications to move away.

Also, the _fast() variants are still ~5% faster than the _safe() ones
after Dave's patch.

5 years agofixed lz4frame with linked blocks
Yann Collet [Mon, 15 Apr 2019 17:28:36 +0000 (10:28 -0700)]
fixed lz4frame with linked blocks

when one block was not compressible,
it would tag the context as `dirty`,
resulting in compression automatically bailing out of all future blocks,
making the rest of the frame uncompressible.
