* Decouple connection objects from the server (#2535)
- Making progress towards being able to use the connection objects on the client side.
* Wait for input writer to complete before calling OnConnectionClosed (#2566)
* Wait for the ConnectionClosed token to stop tracking connections (#2574)
- The prior strategy of waiting for the pipe completed callbacks doesn't work
because blocks are returned to the memory pool after the callbacks are fired.
* Consistently handle connection resets (#2547)
* Provide better connection abort exceptions and logs
* void IConnectionDispatcher.OnConnection
* If we can't find a developer certificate on the certificate store
we will look for a developer certificate on the file system if a
password has been specified for the Development certificate.
* We will look at ${APPDATA}/ASP.NET/https/<<AppName>>.pfx for windows
and fallback to ${HOME}/.aspnet/https/<<AppName>>.pfx
* In case the password wasn't specified through configuration, the file
is not found on the file system or can't be loaded, we won't
do anything.
- Most of the shared code is in the HttpProtocol class (former Frame)
- Virtual calls handle protocol-specific things
- Move the ProcessRequestsAsync loop to HttpProtocol
- Implement HTTP/1.x request processing in Http1Connection and HTTP/2
in Http2Stream, with Http1Connection<T> and Http2Stream<T> subclassing
those classes in order to handle the generic HttpContext parameter
- Split MessageBody into Http1MessageBody and Http2MessageBody,
with MessageBody containing shared member variables and methods
* Improve ConnectionLimitMiddleware and connection pipeline building
* Add IDecrementConcurrentConnectionCountFeature
* Flow connection features from connection middleware
- Added Protocols.Abstractions
- IConnectionHandler.OnConnection takes an IFeatureCollection instead of
IConnectionInfo
- Removed IConnectionContext and IConnectionInformation replaced with
IConnectionTransportFeature
- Updated FrameConnectionContext and FrameContext to have the relevant
state instead of flowing the ConnectionInformation.
- Updated tests
- Added new options to allow configuring the maximum number of concurrent connections and upgraded connections.
- `KestrelServerLimits.MaxConcurrentConnections` defaults unlimited.
- `KestrelServerLimits.MaxConcurrentUpgradedConnections` defaults to unlimited.
- Calls to IHttpUpgradeFeature.UpgradeAsync() will throw when the MaxConcurrentUpgradedConnections limit has been reached.
- Kestrel will close new connections without response when MaxConcurrentConnections is reached.
