There was a race condition between the first poll and any other http request that was sent.
In particular, if you called StartAsync then StopAsync it was possible for the delete to happen before the poll started leading to 400 errors. This change fixes that by making the very first poll
return immediately so that the client can use that to determine if there was an error connecting.
- Added DisposeAsync to the IConnectionFactory. It's responsible for disposing the connection after the pipe has closed.
- Added dispose callback to WithConnectionFactory
- Don't wait for poll request to end before unwinding from the transport
- Make sure all http requests are done before returning from StopAsync in both SSE and longpolling
- Removed SendUtils.PrepareRequst and instead used HttpClient.DefaultRequstHeaders to set the common headers to apply HttpOptions to all outbound requests
- Modified how we check for the user agent request testing
- Cancel reading from the application when initiating a transport stop
- Complete each side of the pipe in the place where the pipe is being consumed
- Errors from sending end up getting sent to the application
- The Running task never throws
- Removes ContinueWith
- React to rename of EndPoint to ConnectionHandler
- Rename UseSockets to UseConnections
- Rename MapEndPoint to MapConnectionHandler
- Rename HttpSocketOptions to HttpConnectionOptions
- Reworked the Client to be based on pipelines instead of Channels
- SendAsync no longer fails if the http request itself fails but the connection is closed as a result.
- Updated tests
- Base64Encoder needed to support multiple messages in the same span of data
* 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
