* Remove the params argument from IClientProxy
- This allows passing arrays without having to explicitly ToArray() or AsEnumerable()
- Added overloads up to 10 arguments
- Added tests
* Initial support for websocket subprotocols
- Exposes a SubProtocol property on WebSocketOptions that picks the
protocol for all connections on the end point.
- This is required for things like mqtt over websockets (the SubProtocol in
this case is something like mqtt or mqttv3.1)
- Added test
#402
We need to close the connection if there is an exception when writing to the transport on the server side. Currently if an exception happens it leaves the connection in an unsable state - after the exception no messages from the server will be sent to the client because the writing loop is terminated. Ignoring the message could cause hangs on the client side since we can fail while writing a completion message. In this case if the client is awaiting the invocation it will hang because the task will never be completed.
* Turned Stream into StreamAsync
- Before we were fire and forgetting the invocation that initiated
the streaming, this changes that so that the caller now has to await
to get the channel.
#899
* Added Cancellation support
- Added ConnectionAbortedToken to the HubConnectionContext. This allows
arbitrary code to access a handle that represents the connection lifetime
without handling OnDisconnectedAsync on the hub itself.
- Expose Abort on HubConnectionContext to allow server side methods to
abort the connection.
- Use the Abort to stop the main loop when unexpected invocation errors happen.
- Use the connection aborted token as unsubscribe from the IObservable and to complete
the IAsyncEnumerator for streaming results.
- Removed ConnectionFactoryDelegate and used Func<IConnection>
- Changed WithLogger that accepts ILoggerFactory to WithLoggerFactory
- Made UseLogger configure the existing ILoggerFactory or create a LoggerFactory
- Add support for setting the log level for console logs
- Updated tests
Before we would rely on error being null to detect whether to read results and we had an additional 'hasResult' field. Now all this information is codified in a field.
* 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.
- Remove timeout and closed the application when the transport closes.
Made some tweaks to TestWebSocketConnectionFeature as a result.
- This uncovered some interesting issues with the WebSocketTransport itself so
further refactoring is needed to make it a bit more solid.
* 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
* Re-layer the .NET Client into Http and non-Http
- Moved IConnection to Sockets.Abstractions and removed
HttpConnection and TransportType dependency.
- Renamed Sockets.Client to Sockets.Client.Http
- Renamed Sockets.Common to Sockets.Common.Http
- Renamed Connection to HttpConnection
- Removed HTTP dependency from HubConnection
- Removed tests that were testing connection logic in HubConnection
#518
* Add support for timing out poll requests
- Default poll request is 110 seconds (like in previous versions of SignalR)
- Use 200 with a 0 content length for timeouts.
- Added support for not timing out while debugging
* 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
* Remove the RequestId from DefaultConnectionContext
- Added a GetHttpContext() extension method on ConnectionContext
- Also fixed an issue not setting LastSeenUtc
- Preventing from closing long polling transport with 204 in case of
error
- Reporting an error to the client if WebSocket was not closed normally
Note in case of ServerSentEvents it is not possible on the client to
tell the difference between when the server closed event stream due to
an exception or because the client left OnConnectedAsync. In both cases
the client sees only that the stream was closed.
Part of: #163
Exceptions thrown when sending or receiving messages would leave the
WebSockets transport in a half-closed state when one of the loops is
closed but the other one is still running preventing from the
Connection.Closed event to be fired.
Fixes: #412
* 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.
- If a message was sent and the application was ended in the same
poll request, the connection would be closed by the time the next poll
came in which resulted in a 404. This change waits until the transport writes
all data before closing it.
- Also fixed a test so that the exception started to show client side.
#469
- We're now using the routing system in a very vanilla way now that
we're not using the URL space as part of the protocol.
- Removed the path argument from the HttpConnectionDispatcher (simplifies code and removes duplication from tests)
* 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
Firefox won't fire EventSource open event until it receives some data. The workaround is to send an empty comment when starting ServerSentEvent transport.
Fixes: #352
* Disable response buffering via the IHttpBufferingFeature
- To make sure SignalR works with servers and middleware
that do perform response buffering, disable it via the
IHttpBufferingFeature for SSE.
- Added test to verify buffering is disabled
- Today we don't end the request if the application completes
but the websocket transport hasn't gotten the receive frame as yet.
This changes adds a WebSocketOptions.CloseTimeout to EndPointOptions
that allows configuring this timeout. When the timeout is reached, we abort
the connection and end the transport task so that the request can end.
- Added tests for websocket timeout and skipped tests for application timeouts
* Fix issue where multiple calls to dispose don't wait properly
- DisposeAsync returned immediately to anyone but the first caller.
This means that it was possible to end the request before properly
waiting on the transport task which means writing after dispose was possible.
- Added a test
