* Suppress false positive warning from MSVC (fuzzer.c)Takayuki Matsuoka2022-08-121-2/+10
| | | | | | | Suppress the following false positive warnings from MSVC: - Disable all arithmetic overflow (C26451) - Suppress C6385: Reading invalid data from 'compressedBuffer'. - Add ULL suffix to unsigned 64-bits constants.

| * fix efficiency of LZ4_compress_HC_destSize()Yann Collet2020-09-281-9/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | LZ4_compress_HC_destSize() had a tendency to discard its last match when this match overflowed specified dstBuffer limit. The impact is generally moderate, but occasionally huge, typically when this last match is very large (such as compressing a bunch of zeroes). Issue #784 fixed for both Chain and Opt implementations. Added a unit test suggested by @remittor checking this topic.

* fix #783Yann Collet2020-08-271-4/+4
| | | | | | | | | | | | | | | | | LZ4_decompress_safe_partial() now also supports a scenario where nb_bytes_to_generate is <= block_decompressed_size And nb_bytes_to_read is >= block_compressed_size. Previously, the only supported scenario was nb_bytes_to_read == block_compress_size. Pay attention that, if nb_bytes_to_read is > block_compressed_size, then, necessarily, it requires that nb_bytes_to_generate is <= block_decompress_size. If both are larger, it will generate corrupted data.

* fix fuzzer tests on dirty contextYann Collet2019-04-151-3/+3
| | | | | | context is no longer dirty after a failed compressed block. Actually, all indexes are fine. It remains compatible with continued streaming, and reset*_fast().

* fixed loadDictHCYann Collet2019-04-091-4/+4

| | | | | it is now a pure initializer, for statically allocated states. It can initialize any memory area, and because of this, requires size.
