Refactor

  • Replace all cowlib modules with hackney-native implementations
  • Remove src/libs/ directory (all modules moved to src/)

Performance

  • HTTP/2 state machine optimizations:
  • Stream caching for recently accessed streams
  • gb_sets for lingering streams (O(log N) vs O(N) lookups)
  • IOList accumulation for header fragments
  • HPACK and QPACK header compression with O(1) static table lookups
  • WebSocket: use rand:bytes/1 instead of crypto:strong_rand_bytes/1 for mask keys

Added

  • h2spec HTTP/2 compliance testing (95% pass rate - 139/146 tests)
  • h2spec_server.erl: Minimal HTTP/2 server for compliance testing
  • h2spec_SUITE.erl: CT suite for running h2spec tests
  • Makefile target: make h2spec-test
  • HTTP/3 E2E tests against real servers
  • hackney_http3_e2e_SUITE.erl: Tests against Cloudflare, Google, quic.tech
  • Makefile targets: make http3-e2e-test, make all-e2e-test
  • HTTP/2 machine benchmarks (hackney_http2_machine_bench.erl)

Bug Fixes

  • Fix HTTP/2 flow control for body sending (use send_or_queue_data/4)
  • Fix async 204/304/HEAD responses not sending done message
  • Fix unknown HTTP/2 frame types not being ignored (RFC 7540 4.1)
  • Fix HTTP/2 frame size validation
