http-2

What's Changed

Bugfixes

• frame buffer was accidentally changing encoding before header packing, which raise invalid compatible encoding errors, due to usage of "String#". this was fixed by using internal append_str´, which does not touch encoding, and calling String.force_encoding` in case the buffer is a mutable string passed by the user.
• dup PING frame payload passed by the us...

What's Changed

• Several changes which improved performance for the common cases. A few highlights:
  • Opting into ruby 3.4 features when possible (such as String#append_as_bytes instead of String#<<)
  • reducing string and array allocations on several places (connection management, frame generation, hpack header compression, etc)
  • "streams recently closed" not having to regenera...

What's Changed

Improvements

• Freezing static tables (used for header huffman coding) correctly. This makes them shareable, which makes http-2 usable across ractors.
• Moved buffer helpers from String refinements into mixins. Refinements impose a relevant performance penalty, unfortunately, despite its cleaner API.
