782bfb858a fixed very minor inefficiency (nbSeq==127) 
The nbSeq "short" format (1-byte)
is compatible with any value < 128.

However, the code would cautiously only accept values < 127.
This is not an error, because the general 2-bytes format
is compatible with small values < 128.
Hence the inefficiency never triggered any warning.

Spotted by Intel's Smita Kumar.

ZSTD_compressSequences_internal assert op <= oend (#1667) 
When we wrote one byte beyond the end of the buffer for RLE
blocks back in 1.3.7, we would then have `op > oend`. That is
a problem when we use `oend - op` for the size of the destination
buffer, and allows further writes beyond the end of the buffer for
the rest of the function. Lets assert that it doesn't happen.

Merge pull request #1658 from facebook/memset 
memset() rather than reduceIndex()
 2019-07-01 15:01:43 -07:00
Yann Collet
621adde3b2 changed naming to ZSTD_indexTooCloseToMax() 
Also : minor speed optimization :
shortcut to ZSTD_reset_matchState() rather than the full reset process.
It still needs to be completed with ZSTD_continueCCtx() for proper initialization.

Also : changed position of LDM hash tables in the context,
so that the "regular" hash tables can be at a predictable position,
hence allowing the shortcut to ZSTD_reset_matchState() without complex conditions.

45c9fbd6d9 prefer memset() rather than reduceIndex() when close to index range limit 
by disabling continue mode when index is close to limit.
