Emma's OSS TODO List

 

NOTE: The below are random ideas of mine, and may not be things I actually work on, or the final state of ideas. Please take with a grain of salt!

• CPython
  •  Zstandard stuff
    • zstd for ios and android
      • iOS https://github.com/beeware/cpython-apple-source-deps/pull/64
      • Android https://github.com/python/cpython/issues/135846
    •  Add oss-fuzz integration?  (canceled,  zstd is already fuzzed)
    • Improve decompression performance
      • optimize output buffer code https://github.com/python/cpython/pull/139976 
      • Optimize compression/decompression when operating on data of a known size
    • Add support for stdlib compression zstd to popular 3rd parties
      • httpx
  • general compression things
    •  Add benchmarks for compression to test output buffer and bindings
      • https://github.com/emmatyping/compression-benchmarks 
      • benchmark current formats
        • zlib
        • lzma
        • bz2
        • zstd
      • Profile and look for opportunities to optimize
    •  Enable usage of Rust implementations of dependencies
      • Add support for bzip2-rs for libzip2 library
      • Add support for zlib-rs for libz/zlib module
    • Provide information about compression modules
      • Provide version information https://github.com/python/cpython/issues/117404
