From 46742636c7b61d5db7dfc8c721d739971f4920c0 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 25 Apr 2026 21:03:54 +0000 Subject: [PATCH] =?UTF-8?q?feat(quic):=20Phase=20L=20=E2=80=94=20wire=20Qu?= =?UTF-8?q?icWebTransportFactory=20into=20nestsClient?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the Kwik stub in :nestsClient with a pure-Kotlin QUIC + WebTransport adapter built on top of :quic. - QuicWebTransportSessionState (in :quic) bundles the QuicConnection + QuicConnectionDriver + the CONNECT bidi stream id and exposes open-bidi-stream / open-uni-stream / send-datagram / poll-incoming-* / close primitives. Stream-type prefix bytes (0x41 / 0x54 + quarter session id) are pushed onto each new stream automatically. close() emits a WT_CLOSE_SESSION capsule before tearing down the QUIC connection. - QuicWebTransportFactory (in :nestsClient/jvmAndroid, replacing KwikWebTransportFactory) drives the full open sequence: 1. UDP connect + QuicConnection.start 2. wait until handshake completes (Status.CONNECTED) 3. open H3 control uni-stream with stream-type 0x00 + the SETTINGS frame (ENABLE_CONNECT_PROTOCOL=1, H3_DATAGRAM=1, ENABLE_WEBTRANSPORT=1) 4. open the Extended CONNECT bidi: HEADERS frame carrying :method=CONNECT, :protocol=webtransport, :scheme=https, :authority, :path, optional Authorization: Bearer 5. wrap the connection + driver + connect stream id in a WebTransportSession adapter that the existing nestsClient MoQ + audio pipeline already targets. - The KwikWebTransportFactory stub + its test are removed; nothing else in :amethyst, :commons, or the audio pipeline changes — the moment connect() returns a session, the rest of PR #2494's stack runs end-to-end. - spotless / ktlint compliance: file rename to match the QuicWebTransportSession class name, comment-style cleanup in TlsConstants and LongHeaderPacket. Build: :amethyst:compileFdroidDebugKotlin succeeds; :nestsClient:jvmTest + :quic:jvmTest both pass. https://claude.ai/code/session_01EC1tfXfap8k8GyKvrxkxZx --- .../transport/KwikWebTransportFactory.kt | 166 --------- .../transport/QuicWebTransportFactory.kt | 172 ++++++++++ .../transport/KwikWebTransportFactoryTest.kt | 43 --- .../quic/connection/EncryptionLevel.kt | 5 +- .../quic/connection/LevelState.kt | 4 +- .../connection/PacketProtectionBuilder.kt | 16 +- .../quic/connection/QuicConnection.kt | 28 +- .../quic/connection/QuicConnectionParser.kt | 11 + .../quic/connection/QuicConnectionWriter.kt | 1 - .../quic/crypto/InitialSecrets.kt | 25 +- .../com/vitorpamplona/quic/frame/Frame.kt | 79 ++++- .../quic/http3/Http3FrameTypes.kt | 1 + .../quic/packet/LongHeaderPacket.kt | 24 +- .../vitorpamplona/quic/packet/PacketTypes.kt | 3 +- .../quic/packet/ShortHeaderPacket.kt | 4 +- .../vitorpamplona/quic/qpack/QpackDecoder.kt | 3 + .../vitorpamplona/quic/qpack/QpackHuffman.kt | 320 ++++++++++++++---- .../quic/qpack/QpackStaticTable.kt | 6 +- .../com/vitorpamplona/quic/tls/TlsClient.kt | 19 +- .../vitorpamplona/quic/tls/TlsClientHello.kt | 2 +- .../vitorpamplona/quic/tls/TlsConstants.kt | 4 +- .../quic/tls/TlsHandshakeMessages.kt | 23 +- .../QuicWebTransportSessionState.kt | 84 +++++ .../quic/webtransport/WtDatagram.kt | 2 +- 24 files changed, 692 insertions(+), 353 deletions(-) delete mode 100644 nestsClient/src/jvmAndroid/kotlin/com/vitorpamplona/nestsclient/transport/KwikWebTransportFactory.kt create mode 100644 nestsClient/src/jvmAndroid/kotlin/com/vitorpamplona/nestsclient/transport/QuicWebTransportFactory.kt delete mode 100644 nestsClient/src/jvmTest/kotlin/com/vitorpamplona/nestsclient/transport/KwikWebTransportFactoryTest.kt create mode 100644 quic/src/commonMain/kotlin/com/vitorpamplona/quic/webtransport/QuicWebTransportSessionState.kt diff --git a/nestsClient/src/jvmAndroid/kotlin/com/vitorpamplona/nestsclient/transport/KwikWebTransportFactory.kt b/nestsClient/src/jvmAndroid/kotlin/com/vitorpamplona/nestsclient/transport/KwikWebTransportFactory.kt deleted file mode 100644 index 0b9cf2f2f..000000000 --- a/nestsClient/src/jvmAndroid/kotlin/com/vitorpamplona/nestsclient/transport/KwikWebTransportFactory.kt +++ /dev/null @@ -1,166 +0,0 @@ -/* - * Copyright (c) 2025 Vitor Pamplona - * - * Permission is hereby granted, free of charge, to any person obtaining a copy of - * this software and associated documentation files (the "Software"), to deal in - * the Software without restriction, including without limitation the rights to use, - * copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the - * Software, and to permit persons to whom the Software is furnished to do so, - * subject to the following conditions: - * - * The above copyright notice and this permission notice shall be included in all - * copies or substantial portions of the Software. - * - * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR - * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS - * FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Until - * then, [connect] throws [WebTransportException] with - * [WebTransportException.Kind.NotImplemented]. - * - * The Phase 3c MoQ framing layer + Phase 3d audio pipeline + Phase 3d-3 - * `AudioRoomConnectionViewModel` are all wired against the - * [WebTransportSession] interface, so the moment this class returns a real - * session the entire stack starts producing audible output without further - * changes upstream. - * - * ## Phase 3b-2 integration plan - * - * ### 1. Maven coordinates (verify before adding) - * - * Kwik is published by Peter Doornbosch (kwik.tech). As of writing the - * coordinates appear to be `tech.kwik:kwik-core` and `tech.kwik:flupke` but - * **this needs verification on the live Maven Central index** — earlier - * versions used different group IDs. Suggested verification command: - * - * ``` - * curl -sf https://repo1.maven.org/maven2/tech/kwik/kwik-core/maven-metadata.xml - * curl -sf https://repo1.maven.org/maven2/tech/kwik/flupke/maven-metadata.xml - * ``` - * - * Known-good versions to try (newest first): 0.11.x, 0.10.x, 0.9.x. - * - * If the `tech.kwik` group fails, fall back to `net.luminis.quic:kwik` (the - * pre-2024 group) but pin to the latest 0.x release on that group. - * - * Add to `gradle/libs.versions.toml`: - * ```toml - * [versions] - * kwik = "0.11.0" # confirm against maven-metadata.xml first - * - * [libraries] - * kwik-core = { group = "tech.kwik", name = "kwik-core", version.ref = "kwik" } - * kwik-flupke = { group = "tech.kwik", name = "flupke", version.ref = "kwik" } - * ``` - * - * Add to `nestsClient/build.gradle.kts` under `androidMain.dependencies`: - * ```kotlin - * implementation(libs.kwik.core) - * implementation(libs.kwik.flupke) - * ``` - * - * Kwik is pure Java with no JNI; both Android and JVM-desktop targets work. - * - * ### 2. Handshake sequence - * - * a. **Resolve UDP socket** to `(authority host, authority port)` — port - * defaults to 443 for `https`/`wss` URLs. - * b. **QUIC dial** with ALPN list `["h3"]` (HTTP/3) via Kwik's connection - * builder. Kwik uses TLS 1.3; pass an `SSLContext` that accepts standard - * CA-issued certs (nests deployments use Let's Encrypt). - * c. **HTTP/3 SETTINGS** exchange via Flupke. Send a control stream with: - * - `SETTINGS_ENABLE_CONNECT_PROTOCOL = 1` (RFC 8441, identifier 0x08) - * - `SETTINGS_ENABLE_WEBTRANSPORT = 1` (WebTransport-H3 draft, identifier 0x2b603742) - * - `SETTINGS_H3_DATAGRAM = 1` (RFC 9297, identifier 0x33) - * Wait for the peer's SETTINGS frame; verify it advertises the same - * WebTransport setting before proceeding. - * d. **Extended CONNECT** request on a new client-bidi stream, as - * compressed HEADERS: - * - `:method = CONNECT` - * - `:protocol = webtransport` - * - `:scheme = https` - * - `:authority = ` (or `:` if non-default) - * - `:path = ` (defaults to `/`, nests uses `/moq`) - * - `Authorization: Bearer ` if non-null - * - `sec-webtransport-http3-draft02 = 1` for legacy server compat - * Read the response HEADERS; on `:status = 2xx` the session is open. - * On 4xx / 5xx throw [WebTransportException] with - * [WebTransportException.Kind.ConnectRejected]. - * - * ### 3. Stream / datagram multiplexing - * - * - **Bidi WT streams**: client opens a QUIC bidi stream; first VarInt - * written is the WT stream-type signal `0x41` followed by the WT session - * ID (the stream ID of the CONNECT bidi). Bytes that follow are - * application data (MoQ frames, in our case). - * - **Uni WT streams** (used by MoQ for OBJECT_STREAM): client opens a - * QUIC uni stream; first VarInt is `0x54` then the WT session ID. - * - **WT datagrams** (used by MoQ for OBJECT_DATAGRAM): wrap each app - * payload in an HTTP/3 DATAGRAM (RFC 9297) with the WT quarter-stream-id - * prefix, then push via Kwik's QUIC datagram API. - * - * Inbound peer-initiated streams: detect WT type bytes, route to either - * the [WebTransportSession.incomingUniStreams] flow or the (Phase 3b-3 if - * needed) bidi-stream flow. - * - * ### 4. Lifecycle - * - * - Spawn one coroutine to demux inbound QUIC streams into WT - * bidi/uni/datagram channels. - * - On [WebTransportSession.close], send a `WEBTRANSPORT_SESSION_CLOSE` - * capsule (an HTTP/3 capsule of type 0x2843) on the CONNECT bidi, then - * `connection.close()` on the underlying Kwik QUIC connection. - * - * ### 5. Test strategy - * - * - Unit-test the WT framing helpers (varint stream-type prefix, capsule - * encode/decode) in `commonTest` before touching Kwik. - * - Instrumented `@LargeTest` against `nostrnests.com`: - * ``` - * val factory = KwikWebTransportFactory() - * val session = factory.connect("nostrnests.com", "/moq") - * assertTrue(session.isOpen) - * session.sendDatagram(byteArrayOf(0x40)) // CLIENT_SETUP varint - * session.close() - * ``` - * - Validate against the nests-rs reference server first (run locally with - * `cargo run` from the `nests` repo) before targeting production - * `nostrnests.com` — easier to read the server-side logs. - * - * ### Risks / open questions - * - * - **Kwik HTTP/3 (Flupke) maturity**: Flupke is functional but its - * Extended CONNECT support has not been tested against WebTransport in - * the field as far as the maintainer's docs go. Worst case: build the - * CONNECT request manually using Kwik's lower-level HTTP/3 frame API. - * - **Draft churn**: WebTransport-H3 is a moving target. Pin to - * `draft-02` (or whatever nests serves at integration time) and - * advertise both legacy and current setting IDs. - * - **Self-signed certs in dev**: nests' local docker compose ships a - * self-signed cert; expose a `trustAllCerts: Boolean` constructor flag - * for development builds (NOT in release). - * - **Android API**: Kwik uses [DatagramChannel] + [SocketAddress] which - * work on Android. No JNI / no Cronet, so APK size impact is small. - */ -class KwikWebTransportFactory : WebTransportFactory { - override suspend fun connect( - authority: String, - path: String, - bearerToken: String?, - ): WebTransportSession = - throw WebTransportException( - kind = WebTransportException.Kind.NotImplemented, - message = - "Kwik-backed WebTransport handshake not yet implemented.
