- This change aims to clean up the feature interfaces
used by kestrel and exposed by protocol absractions. It splits out the
IConnectionTransportFeature into smaller features that may or may
not be implemented on the connection.
- Added all of the features from Socket.Abstractions
in an attempt to make it go away completely. As a result
the helper methods and extensions have all been added here.
- Change IConnectionHandler to take TransportConnection. This cleans up the interface and makes it more explicit what features are required by Kestrel

* Clean up some of protocol abstractions
- Renamed PipeConnection to DuplexPipe
- Removed MemoryPool from ConnectionContext
- Work around value tuple issue on net471
- Based on the changes you made earlier (f4d27e6), we trigger OnConnectionClosed before the socket is disposed in the SocketTransport. This moves the call to Output.Complete to happen after and thus fixes the race.
* 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.
- Always add the TlsConnectionFeature when the HttpsConnectionAdapter runs
- Implemented the ITlsApplicationProtocolsFeature on the existing TlsConnectionFeature
- Removed Kestrel.Tls
- This should improve the performance of handling buffers by (eventually)
removing GCHandle churn for Kestrel's already pinned buffers.
- Made the Sockets transport target both netcoreapp2.1 and netstandard2.0 to use new
APIs
- Disable API check for the sockets transport
* More reliably swallow accept errors during shutdown
* Handle and log connection reset errors thrown from accept
* Don't trace errors for server-aborted connections
* Make Sockets the default transport
* Create separate Libuv and Sockets functional test projects
* Fix functional tests that fail with Sockets
* Moved OneToTenThreads test to Kestrel.Transport.Libuv.Tests
* Fix systemd activation tests to use libuv transport
* Dispose Sockets PipeFactory
* Improve Socket's server-side abort handling
* Add explicit rebinding test
- 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
- Use the pipe events and removed the Tasks from ConnectionContext
- Remove OnConnectionClosed from FrameConnection. Since the `FrameConnetion` is a single middleware, not the entire pipeline, we shouldn't need to wait on the connection close there.
- It seems like the callbacks are rooted on the pipe even after they fire. This needs to be investigated in pipelines.
Current path is:
Parser -> HttpVersion Enum -> Get Version String -> Set `HttpVersion` with string -> Convert back to Enum
Can just set the enum directly since its already parsed.
Also using the const rather than strings; where the strings are in code
* Added initial connection middleware pipeline
- Implemented IConnectionBuilder on ListenOptions. Kept IConnectionAdapter for now.
- Delay the configure callback for ListenOptions until the server has started.
- Added ConnectionLimitMiddleware and HttpConnectionMiddleware
- Expose ConnectionAborted and ConnectionClosed on ConnectionContext and
IConnectionTransportFeature
- Updated the tests
- Removed IConnectionApplicationFeature
- Moved Application to IConnectionTransportFeature
PackageLineup is a way to manage PackageReference versions across large projects. It removes the version information from the repository and instead pulls the information from an external "lineup" file.
What works:
- HTTP/2 over TLS1.2 with ALPN
- Request and response flow
- Headers are compressed and decompressed with HPACK
- Request body can be read by streams (if present)
- MVC template app with individual auth works fine
- PRIORITY frames are validated
- RST_STREAM frames are validated and abort streams
- SETTINGS frames are validated and ACKed
- PING frames are validated and ACKed
- GOAWAY frames stop connections
- WINDOW_UPDATE frames are validated
- CONTINUATION frames are sent for large header blocks
What doesn't work yet:
- Flow control in either direction
- It's not possible to encode a single header across more than one frame
- Affects only a very large header (name and value combined ~16KB long)
- Request trailers
- Response trailers
- Limits and timeouts in `KestrelServerLimits` are not enforced on HTTP/2
- HPACK use is very limited on the send side
- Literals are not Huffman-encoded
- Common headers (e.g. "server: Kestrel") are never indexed
- Honoring client settings
- Some error checking is still missing (e.g. validating incoming frame size)
- 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
* UvPipeHandle.Open(IntPtr) and underlying interop
* LibuvConstants.ENOTSUP
* IEndpointInformation.HandleType along with ListenOptions extra ctor and handle type re-specification
* Exception-based auto-detection of socket type in Listener, accept socket creation support for detected handle types in ListenerContext
* Added systemd Unix socket activation 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.
