zlib-ng

• Show HN: Pzip- blazing fast concurrent zip archiver and extractor

  Please note that allowing for 2% bigger resulting file could mean huge speedup in these circumstances even with the same compression routines, seeing these benchmarks of zlib and zlib-ng for different compression levels:

  IMO the fair comparison of the real speed improvement brought by a new program is only between the almost identical resulting compressed sizes.

• Introducing zune-inflate: The fastest Rust implementation of gzip/Zlib/DEFLATE
  2 projects | /r/rust | 11 Feb 2023

  It is much faster than miniz_oxide and all other safe-Rust implementations, and consistently beats even Zlib. The performance is roughly on par with zlib-ng - sometimes faster, sometimes slower. It is not (yet) as fast as the original libdeflate in C.

• Zlib Critical Vulnerability

  Zlib-ng doesn't contain the same code, but it appears that their equivalent inflate() when used with their inflateGetHeader() implementation was affected by a similar problem: https://github.com/zlib-ng/zlib-ng/pull/1328

  Also similarly, most client code will be unaffected because `state->head` will be NULL, because they (most client code) won't have used inflateGetHeader() at all.

  I wonder if zlib-ng would make a difference, since it has a lot of optimizations for modern hardware.

  zlib-ng also has adler32 implementations optimized for various architectures: https://github.com/zlib-ng/zlib-ng

  Might be interesting to benchmark their implementation too to see how it compares.

• games-emulation/dolphin-9999 is failing to build because devs switched to minizip-ng and zlib uses minizip. I'm not sure how to get it to build now, details in post.

  (2) There are many packages that rely upon zlib and minizip and switching those underlying dependencies is easier said than done. We can't drop zlib completely and switch: "The idea of zlib-ng is not to replace zlib, but to co-exist as a drop-in replacement with a lower threshold for code change." - https://github.com/zlib-ng/zlib-ng

  There are already active zlib forks (e.g. https://github.com/zlib-ng/zlib-ng), the problem is with having people move to them. It takes a lot of effort to move mindshare from the original version to a fork, there's some historical examples of it happening, but not a ton.
