* Features everywhere
- The goal here is to move things closer to the final design where
ConnectionContext represents a very low level primitive that represents
any connection like transport. As part of that change, we remove unnecessary
properties like User and move those into features. They temporarily live in the same
assembly but they are not required by ConnectionContext.
- Used features for Hubs instead of Metadata
- Metadata is no longer thread safe
* Replace ConnectionContext with HubConnectionContext
- The SocketDelegate implementation owns the transport pipe,
it's a single producer single consumer model. SignalR needs to support
multiple producers so that broadcast, return values and sending to individual
connections works. This change introduces a multi producer channel that is used
by all producers to copy data to the transport safely. This will make the move
to pipelines easier.
* Added support for non blocking sends on HubConnection
- Renamed Invoke to InvokeAsync
- Add support for non blocking send to TS client
- Add tests to make sure that non blocking sends don't send responses
* Merge transport and hub protocols
- This change merges the transport and hub protocols into a single protocol. The
idea being that sockets in a purely streaming layer that sends frames from the underlying
transport. This makes things like TCP possible and doesn't impose a framing layer at the lowest
level. This will make it possible to build servers like kestrel on top of the TCP layer.
- The Message was removed from the lowest layer of the stack and pushed into the hubs layer. Hub invocations
are framed with what was before the transport protocol. Connections also need to state upfront if they support
binary or not. This will determine how data will be serialized to the specific connection.
- Changed the SSE parser and writer to be strictly SSE without any of the transport protocol specific
information.
- To ensure we aren't using types in the wrong layers
- Moved protocol logic into SignalR
- Socket.Abstractions is now the root of the universe, Sockets.Common will likely be removed
or turned into Sockets.Common.Http.
- Move SSE parser to Sockets.Client and SSE writer into Sockets.Http
- Moved tests into the appropriate test projects
- Updated the spec
* Split http and non-http layers
- This change introduces Microsoft.AspNetCore.SignalR.Http
and Microsoft.AspNetCore.Sockets.Http which expose extension methods
on IAppBuilder for wiring up a sockets and signalr pipeline.
* 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)
