These are mechanical: every encoder already does `context.Features.Get()` — change the parameter name from `context` to `features` and remove the `.Features` indirection. - -**Files:** -- Modify: `src/TurboHTTP/Protocol/Syntax/Http11/Server/Http11ServerEncoder.cs` -- Modify: `src/TurboHTTP/Protocol/Syntax/Http2/Server/Http2ServerEncoder.cs` -- Modify: `src/TurboHTTP/Protocol/Syntax/Http3/Server/Http3ServerEncoder.cs` -- Modify: `src/TurboHTTP/Protocol/Syntax/Http2/StreamState.cs` - -- [ ] **Step 1: Update Http11ServerEncoder** - -Change `Encode` signature from `RequestContext context` to `IFeatureCollection features`. Replace all `context.Features.Get()` with `features.Get()`. Remove `using TurboHTTP.Streams.Stages.Server;`, add `using Microsoft.AspNetCore.Http.Features;` if not already present. - -The method signature becomes: -```csharp -public int Encode(Span destination, IFeatureCollection features, bool isChunked = false, bool connectionClose = false) -``` - -All internal access changes from `context.Features.Get()` to `features.Get()`. - -- [ ] **Step 2: Update Http2ServerEncoder** - -Change `EncodeHeaders` signature: -```csharp -public IReadOnlyList EncodeHeaders(IFeatureCollection features, int streamId, bool hasBody) -``` - -Change `BuildHeaderList` signature: -```csharp -private static void BuildHeaderList(IFeatureCollection features, List headers) -``` - -Replace all `context.Features.Get()` → `features.Get()`. - -- [ ] **Step 3: Update Http3ServerEncoder** - -Change `EncodeHeaders` signature: -```csharp -public HeadersFrame EncodeHeaders(IFeatureCollection features) -``` - -Change `BuildHeaderList` signature: -```csharp -private static void BuildHeaderList(IFeatureCollection features, List<(string Name, string Value)> headers) -``` - -Replace all `context.Features.Get()` → `features.Get()`. - -- [ ] **Step 4: Update Http2 StreamState** - -Replace the `RequestContext` field and methods: -- Change `private RequestContext? _requestContext;` to `private IFeatureCollection? _features;` -- Change `SetTurboContext(RequestContext context)` to `SetFeatures(IFeatureCollection features)` → `_features = features;` -- Change `GetTurboContext()` to `GetFeatures()` → `return _features;` -- Remove `using TurboHTTP.Streams.Stages.Server;`, add `using Microsoft.AspNetCore.Http.Features;` - -- [ ] **Step 5: Commit** - -``` -git add src/TurboHTTP/Protocol/Syntax/Http11/Server/Http11ServerEncoder.cs src/TurboHTTP/Protocol/Syntax/Http2/Server/Http2ServerEncoder.cs src/TurboHTTP/Protocol/Syntax/Http3/Server/Http3ServerEncoder.cs src/TurboHTTP/Protocol/Syntax/Http2/StreamState.cs -git commit -m "refactor: update protocol encoders to accept IFeatureCollection" -``` - ---- - -## Task 5: Protocol State Machines + Session Managers - -Update all `OnResponse` implementations and request-creation paths to use `IFeatureCollection` and `FeatureCollectionFactory`. - -**Files:** -- Modify: `src/TurboHTTP/Protocol/Syntax/Http10/Server/Http10ServerStateMachine.cs` -- Modify: `src/TurboHTTP/Protocol/Syntax/Http11/Server/Http11ServerStateMachine.cs` -- Modify: `src/TurboHTTP/Protocol/Syntax/Http2/Server/Http2ServerStateMachine.cs` -- Modify: `src/TurboHTTP/Protocol/Syntax/Http2/Server/Http2ServerSessionManager.cs` -- Modify: `src/TurboHTTP/Protocol/Syntax/Http3/Server/Http3ServerStateMachine.cs` -- Modify: `src/TurboHTTP/Protocol/Syntax/Http3/Server/Http3ServerSessionManager.cs` -- Modify: `src/TurboHTTP/Protocol/ProtocolNegotiatingStateMachine.cs` - -- [ ] **Step 1: Update Http10ServerStateMachine** - -Two changes: -1. Request creation (in `DecodeClientData`): Replace `ServerContextFactory.Create(feature, hasBody, ...)` with `FeatureCollectionFactory.Create(feature, hasBody, ...)`. Change `_ops.OnRequest(context)` to `_ops.OnRequest(features)` (variable rename). -2. `OnResponse`: Change signature to `public void OnResponse(IFeatureCollection features)`. Replace `context.Features.Get()` → `features.Get()`. - -Update using: replace `using TurboHTTP.Streams.Stages.Server;` with nothing (no longer needed for RequestContext). Add `using Microsoft.AspNetCore.Http.Features;` if missing. Keep `using TurboHTTP.Server;` for FeatureCollectionFactory. - -- [ ] **Step 2: Update Http11ServerStateMachine** - -Same two changes: -1. Request creation (~line 139): `ServerContextFactory.Create(...)` → `FeatureCollectionFactory.Create(...)`, variable `context` → `features`. -2. `OnResponse` (~line 167): Change parameter to `IFeatureCollection features`. Replace all `context.Features.Get()` → `features.Get()`. The encoder call changes from `_encoder.Encode(span, context, ...)` to `_encoder.Encode(span, features, ...)`. - -- [ ] **Step 3: Update Http2ServerStateMachine + SessionManager** - -StateMachine: `public void OnResponse(IFeatureCollection features) => _sessionManager.OnResponse(features);` - -SessionManager `OnResponse` (~line 129): Change parameter to `IFeatureCollection features`. Replace `context.Features.Get()` → `features.Get()`. The `GetStreamIdFromContext(context)` call needs to change to `GetStreamIdFromFeatures(features)` (or inline: `features.Get()?.StreamId ?? -1`). - -SessionManager request creation (~line 541): Replace `ServerContextFactory.Create(...)` → `FeatureCollectionFactory.Create(...)`. Change `context.Features.Set(...)` → `features.Set(...)`. The StreamState call `state.SetTurboContext(context)` → `state.SetFeatures(features)`. - -The encoder call `_responseEncoder.EncodeHeaders(context, streamId, hasBody)` → `_responseEncoder.EncodeHeaders(features, streamId, hasBody)`. - -- [ ] **Step 4: Update Http3ServerStateMachine + SessionManager** - -Same pattern as H2: - -StateMachine: `public void OnResponse(IFeatureCollection features) => _sessionManager.OnResponse(features);` - -SessionManager: Same changes as H2 — parameter rename, `FeatureCollectionFactory.Create()`, `features.Get/Set`, encoder accepts `IFeatureCollection`. - -- [ ] **Step 5: Update ProtocolNegotiatingStateMachine** - -```csharp -public void OnResponse(IFeatureCollection features) => _inner!.OnResponse(features); -``` - -Remove `using TurboHTTP.Streams.Stages.Server;` if no longer needed. - -- [ ] **Step 6: Commit** - -``` -git add src/TurboHTTP/Protocol/ -git commit -m "refactor: update all state machines and session managers to IFeatureCollection" -``` - ---- - -## Task 6: HttpConnectionServerStageLogic + Connection Stages + Engines - -Update the core stage logic, all five connection stages, and all five engine classes. The connection stages and engines are mostly mechanical port-type changes. - -**Files:** -- Modify: `src/TurboHTTP/Streams/Stages/Server/HttpConnectionServerStageLogic.cs` -- Modify: `src/TurboHTTP/Streams/Stages/Server/Http10ServerConnectionStage.cs` -- Modify: `src/TurboHTTP/Streams/Stages/Server/Http11ServerConnectionStage.cs` -- Modify: `src/TurboHTTP/Streams/Stages/Server/Http20ServerConnectionStage.cs` -- Modify: `src/TurboHTTP/Streams/Stages/Server/Http30ServerConnectionStage.cs` -- Modify: `src/TurboHTTP/Streams/Stages/Server/ProtocolNegotiatorConnectionStage.cs` -- Modify: `src/TurboHTTP/Streams/Http10ServerEngine.cs` -- Modify: `src/TurboHTTP/Streams/Http11ServerEngine.cs` -- Modify: `src/TurboHTTP/Streams/Http20ServerEngine.cs` -- Modify: `src/TurboHTTP/Streams/Http30ServerEngine.cs` -- Modify: `src/TurboHTTP/Streams/NegotiatingServerEngine.cs` - -- [ ] **Step 1: Update HttpConnectionServerStageLogic** - -Key changes: -1. Field types: `Outlet` → `Outlet`, `Inlet` → `Inlet`, `Queue` → `Queue` -2. `OnRequest(IFeatureCollection features)` implementation: same logic, different type -3. Response handler (`_inResponse` onPush): `var response = Grab(_inResponse);` now gives `IFeatureCollection`. `_sm.OnResponse(response)` already matches new interface. `response.Features.Get()` → `response.Get()` (no `.Features` needed). `ServerContextFactory.Return(response)` → `FeatureCollectionFactory.Return(response)`. -4. Connection info: The `_connectionInfo` field changes from `TurboConnectionInfo?` to `TurboHttpConnectionFeature?`. In `OnNetworkPush` where `TransportConnected` is handled, create `TurboHttpConnectionFeature` directly instead of `TurboConnectionInfo`. -5. Remove `using TurboHTTP.Server;` for TurboConnectionInfo. Add `using Microsoft.AspNetCore.Http.Features;`. - -The `IServerStageOperations.ConnectionInfo` property changes from `TurboConnectionInfo?` to `IHttpConnectionFeature?` — return `_connectionFeature`. - -- [ ] **Step 2: Update all five connection stages** - -Each connection stage defines four ports with explicit types.
