* Progress towards splitting the layers
- This is based on the work anurse did in anurse/endpoint-middleware-spike to
introduce a connection middleware pipeline that mimics much of our http
pipeline. The intent is that this layer will be generic enough to build both
SignalR and Kestrel on top of but we're not there yet. This change makes incremental
progress towards splitting apart sockets and http so that we can add the tcp transport
without breaking everything all at once.
- Created Microsoft.AspNetCore.Sockets.Abstractions where the primitives for
sockets live. That includes, ConnectionContext (formerly Connection), EndPoint,
ISocketBuilder, SocketDelegate, etc.
- ConnectionContext isn't in it's final form as yet, it still very closely mirrors
the original Connection object we had so that tests continue to pass.
- The HttpConnectionDispatcher doesn't know about EndPoint anymore, it just cares
about invoking the SocketDelegate.
- EndPointOptions has been removed as part of this change as it coupled http specific configuration
to the end point type. There's a new HttpSocketOptions that needs to be passed into MapSocket calls.
- Updated the tests to deal with the API changes.
* convert to new protocol
* removed InvocationDescriptorRegistry because we're not yet sure about custom protocols
* update SocialWeather sample
* Moving ts client to using new protocol
* make the functional tests a little easier to run on ctrl-f5
* Fixed parameter count mismatch when invoking methods with wrong case
- Hub methods were being tracked with 2 dictionaries, one for parameter names
the other for callbacks. This change introduces a single dictionary that stores
the hub name to a HubMethodDescriptor. That descriptor stores the parameter types
and method info for the bound hub method.
- The callback is now just an invoke method on the HubEndPoint itself.
- Added tests for case sensitivity in hub method names
* Handle misbehaving user code
- Execute EndPoint logic on a threadpool thread
- Turn synchronous exceptions into async ones to unify the
error handling
- Added tests
* Allow processing of other incoming invocations in parallel
- Don't wait on the response of an invocation to pick up
the next message from the channel.
- Unhandled exceptions should continue bubbling up correctly
* Use TryRead and TryWrite
- Use TryWrite to avoid errors on channel close for /send requests
- Use TryRead until it returns false for all transports but long polling
- Remove Streaming* classes from Sockets. The main
API will be channels based and streaming transports
will use the PipelineChannel (formerly FramingChannel) to
access messages.
- Added WriteAsync and ReadAsync to Connection and hid
the IChannelConnection from public API.
- Also fixed the fact that unknown methods caused server side
exceptions.
- Changed the consumption pattern to WaitToReadAsync/TryRead to avoid
exceptions.
- React to API changes
* Need a separate set of primitives to handle messaging
* Using Channels (not Pipelines!) to provide the data flow for messaging
* All transports are now "message" based transports
* Added an adaptor to convert message-based transports to serve
streaming endpoints
Making sure that OnConnected/OnDisconnected events are invoked correctly (e.g. if invoking OnDisconnectedAsync on hub threw we would not call OnDisconnectedAsync on lifetime manager and therefore we would continue to use/track connections that were already closed)
- Changed IHubConnectionContext and friends to be generic.
- Hub by default is Hub<IClientProxy>. We'll enable dynamic and arbitrary TClients in another commit.
- Moved the IHubConnectionContext implementation out of HubEndPoint
- Added IHubContext to allow getting at the publish side of things without
being in side the hub. The HubEndPoint now injects this as well.
- HubContext has the implementation of the IHubConnectionContext
- Moved ISignalRBuilder and SignalRBuilder into their own files
