* Progress towards deleting Sockets.Abstractions
- Moved our custom DefaultConnectionContext to Sockets.Http and renamed it to HttpConnectionContext.
- Renamed ConnectionManager to HttpConnectionManager
- Use DefaultConnection in tests and benchmarks
- Delete ConnectionMetadata
- React to rename of EndPoint to ConnectionHandler
- Rename UseSockets to UseConnections
- Rename MapEndPoint to MapConnectionHandler
- Rename HttpSocketOptions to HttpConnectionOptions
- The long polling transport simulates a persistent connection
over multiple http requests. In order to expose common http request
properties, we need to copy them to a fake http context on the first poll
and set that as the HttpContext exposed via the IHttpContextFeature.
- 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.
