* Remove unnecessary state machines in DefautHubDispatcher
- Remove state machines for async tail calls
- Added fast path for auth check when there are no policies
- Log from inside of HubConnectionContext if the user callback failed.
- Use ThreadPool.QUWI instead of Task.Factory.StartNew.
- Remove try catch from HubConnectionHandler
* Simplify error handling in HubConnectionHandler
- Since we execute hub methods inline, there's no need to abort the connection on unexpected exceptions.
- Don't pass the cancellation token to ReadAsync, instead just use CancelPendingRead.
- Don't treat OperationCancelledException errors as errors.
- Add a SkipNegotiation flag to the .NET and ts client
to allow skipping the negotiation phase. Don't infer it based on the transport type.
- Updated the negotiate protocol to support returning a redirect url
- Added support to .NET client to handle redirect negotiations
- Handle poorly written endpoints that sends infinite redirects
- Added access token support and an infinite redirect guard
- Add delete handler for stopping the transport
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.
- Make SerializedHubMessage and SerializedMessage
public
- Made HubConnectionStore public
- Move SendUtils and Utils to the internal folder
- Make Microsoft.AspNetCore.Http.Connections.Common/Internal public.
- Move InvocationRequest to internal folder
- 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
- Get rid of LimitArrayPoolWriteStream and use MemoryBufferWriter in its place in the MessagePackProtocol implementation.
- Added tests for MemoryPoolBufferWriter and fixed a bug in CopyToAsync
- Added CopyTo(`IBufferWriter<byte>`)
- Changed MemoryBufferWriter to fill the underlying arrays that back segments, the segment size is now a minimum.
This change rationalizes the 2 very similar abstractions that exist in Connections.Abstractions, IConnection and ConnectionContext. It also introduces an IConnectionFactory to SignalR that is used to create a new ConnectionContext for a HubConnection.
- HubConnection just completes both ends of the transport pipe instead of calling DisposeAsync.
- Implemented ConnectionContext on HttpConnection and added HttpConnectionFactory
- Updated tests
- There are too many issues and questions with respect to back pressure and the buffering policy we should use when the client being streamed to can't support the data being pushed via OnNext.
As a result, we're dropping support for IObservable but keeping ChannelReader and we'll eventually support IAsyncEnumerable when that makes it into the BCL.
- Add sample showing Observable -> ChannelReader adaption
- Don't create the PipeWriterStream per operation, make it per Connection
- Reduce the buffer size for CopyToAsync operations to 4K where possible instead of 81K (the default)
- Closing pipes gracefully in most cases. The only case where we forcefully close the pipes is during application shutdown
- Return 404 if sending to connection after disposal
- Added tests
- Rename file to HttpTransportType.cs
- Add HttpTransportType.None
- Move All to static readonly field
- Make TransportType on client and service HttpConnectionOptions consistent
- Move setting defaults into ctor
- Use the AddLogging extension method by default in the HubConnection
- Removed WithConsoleLogger extension methods
- Removed WithLoggerFactory extension method (moved to test only)
- Added WithLogger that uses the new the new ILoggerBuilder
- Ripped of Kestrel's SocketConnection to make a TcpConnection
IConnection implementation.
- Fixed issue with SignalR assuming there will always be a non-null user
on the ConnectionContext.
- Renamed StreamPipeConnection to PipeReaderFactory
- Flow the transport cancellation token to the CopyToAsync routine
- Other small cleanup and nits to make the style consistent with the other pipe reader loops
- Return a cancelled ValueTask from PipeWriterStream.WriteAsync
- Move event stream request to start itself
- We no longer need to pass the tcs through.
- It also cleans up handling failure in start since the application pipe hasn't been read or written to
- 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
- 5 seconds seems to be too low for long polling's RTT. We often see super flaky tests and it seems like this is the best fix. Ideally, we would do something more sophisitcated than just timeout the entire time to parse.
- We made a change to not initialize pipes up front
on connection creation. That change make it null ref in disposal because we didn't check if the pipes were initialized.
- Added a test
- Also fixed the EchoConnectionHandler in the functional ts tests.
