fdeflate

Release v0.3.7 (#42)

• Optimized decoding of streams that use fixed huffman blocks (#38, #39)

Release v0.3.6 (#36)

This release improves end-to-end decoding peformance for PNG images by 10% on average, with select images benefitting by as much as 50%. These improvements were inspired by the algorithms in zune-inflate.

• Optimized building the Huffman table, which helps the performance of small images (#31)
• Dropped the specialized fast path for a hardcoded Huffman table, which is no longer necessary (#32)
• Add a fast path to the DEFLATE decoding loop that processes more bytes at a time, benefitting performance on large images (#34)
• Re-add test files into the crates.io tarball since they are so small. They may be removed in the future if they grow in size (#35)

• Fix handling of invalid inputs, so that errors are consistently detected regardless of how the input is "chunked" when feeding it into the decompressor.
• Add more fuzz testing.

Release 0.3.4 (#20)

• Fix bug where Decompressor::read might fail to return an error for a truncated deflate stream if the output buffer had room for exactly one more byte of data.

Release 0.3.3 (#18)

• Add decompress_to_vec_bounded method.

Release 0.3.2 (#16)

• Allow decoding into buffers without extra space.

• Strengthen postconditions on Decompressor::read.
• Add more fuzz testing.

• Added support for decoding arbitrary zlib streams.
