fix: ZSTD_BUILD_DECOMPRESSION message
 2023-08-22 13:33:47 -07:00
Nick TerrellandNick Terrell bd02c9be6e No longer reject dictionaries with literals maxSymbolValue < 255 
We already have logic in our Huffman encoder to validate Huffman tables with missing symbols.
We use this for higher compression levels to re-use the previous blocks statistics, or when the dictionaries table has zero-weighted symbols.
This check was leftover as an oversight from before we added validation for Huffman tables.

I validated that the `dictionary_loader` fuzzer has coverage of every line in the `ZSTD_loadCEntropy()` function to validate that it is correctly testing this function.

Unpoison Workspace Memory Before Custom-Free
 2023-08-16 10:18:31 -07:00
W. Felix Handte 9987d2f594 Unpoison Workspace Memory Before Freeing to Custom Free 
MSAN is hooked into the system malloc, but when the user provides a custom
allocator, it may not provide the same cleansing behavior. So if we leave
memory poisoned and return it to the user's allocator, where it is re-used
elsewhere, our poisoning can blow up in some other context.
