| * fix out-of-bound read within LZ4_decompress_fast()Yann Collet2019-04-172-11/+23
| | | | | | | | | | | | | | | | | | | | | | and deprecate LZ4_decompress_fast(), with deprecation warnings enabled by default. Note that, as a consequence of the fix, LZ4_decompress_fast is now __slower__ than LZ4_decompress_safe(). That's because, since it doesn't know the input buffer size, it must progress more cautiously into the input buffer to ensure to out-of-bound read.

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

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.

| * decompress*_fast() function do not generate deprecation warningsYann Collet2019-04-151-13/+14
| | | | | | | | | | | | | | | | | | 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.
| * fixed lz4frame with linked blocksYann Collet2019-04-151-11/+9
|/ | | | | | | 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.
