Version 1.0.9 contains a fix to "integer overflow" problem. This happens when "one-shot" decoding API is used (or input chunk for streaming API is not limited), input size (chunk size) is larger than 2GiB, and input contains uncompressed blocks. After the overflow happens, memcpy is invoked with a gigantic num value, that will likely cause the crash. Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression. The specification of the Brotli Compressed Data Format is defined in RFC 7932. Brotli is open-sourced under the MIT License. You can download and install brotli using the vcpkg dependency manager.
Features
- Brotli uses a pre-defined dictionary, in addition to the dynamically populated ("sliding window") dictionary
- Brotli is a compression algorithm developed by Google and works best for text compression
- Brotli is primarily used by web servers and content delivery networks to compress HTTP content
- Brotli's sliding window is limited to 16 MiB
- Brotli compression is generally used as an alternative to gzip, as Brotli provides better overall compression
- Brotli is available as a port for Android in a terminal-interface with its own shared library
