* rename getid to negotiate
* also change SSE and Long Polling to require a pre-established connection
* disallow changing transports mid-connection; return a 400 response if the user attempts to do so
* 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
- Fixed ChannelConnection to use IChannel<T> for
both sides of the connection. This allows use to close both the
input and the output when we are tearing down.
- Use TryComplete instead of complete to avoid exceptions thrown on
Complete(), particularly ChannelClosedException.
* 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)
- `HubEndPoint<T>` : `RpcEndPoint<T>` where T is the Hub type. Optimizing for a single hub per connection here.
- Hubs get OnConnectedAsync and OnDisconnectedAsync methods that are invoked at the right time and with the right scope.
- Introduced HubLifetimeManager<THub> (naming TBD) which is the center of the universe for Hub behaviors.
- Exposes a list of connections for user code to act on
- The connection list is thread safe (uses a concurrent dictionary under the hood)
- Removed the Bus and just used the connection list in the samples
