Punk-0.48

Changes for version 0.48 - 2026-09-09

  • ADDS: websocket routes work over HTTP/2 through Extended CONNECT (RFC 8441). There is no 101, no Upgrade header and no Sec-WebSocket-Key on a multiplexed transport, so the handshake is new - but the RFC 6455 codec above it is the same one the HTTP/1.1 path uses. An Extended CONNECT is routed as the GET it stands in for, and the origin check still applies to it.
  • ADDS: sse routes and $c->stream work over HTTP/2 and over TLS. Both ran on Hyperman's detach, which hands over a file descriptor and so refuses an h2 stream and a TLS session; they now fall through to Hyperman's ABI v6 stream handle, which sends status, headers and body pieces through the server.
  • A stream reset by the peer, or a client that goes away, now reaches the handler: an sse stream's close callback fires and a $c->stream drain settles. HTTP/1 could only infer this from a dead connection, and a multiplexed transport cannot.
  • No Connection and no Transfer-Encoding on an HTTP/2 or HTTP/3 streamed response. Both are hop-by-hop and forbidden there.
  • A refused detach falls through to the next transport instead of answering 503.
  • A die mid-stream truncates on the stream handle too, through Hyperman's v7 stream_abort: RST_STREAM on HTTP/2, a connection reset on TLS. A streamed body has no declared length, so ending cleanly is the claim that it is whole.
  • Requires Hyperman 0.45.
