- This PR attempts to move things where they are needed instead of where they
happened to be used. As a result we should now have Sockets.Abstractions and
Sockets down to the minimal set of things required to make them run.
Sockets.Abstractions should go away in favor of Protocol.Abstractions and
Sockets contains the EndPoint abstraction and related types.
- Moved ConnectionManager and friends to
Sockets.Http.
-Removed Sockets and moved everything into Sockets.Abstractions.
- Moved DefaultConnection and put it in Sockets.Abstractions.
* Do over the websocket transport
- Unify client and server logic (no code sharing yet)
- Removed use of cancellation tokens to communicate shutdown and instead used the pipe reader and socket abort.
- Added CloseTimeout to HttpOptions
* 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
- 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.
* 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
