* 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 a ConnectionAbortedException to Transport.Abstractions
- To avoid hard coding TaskCanceledException in each transport
- This PR tries to keep compatibility by converting the ConnectionAbortedException
to a TaskCanceledException on exceptions in FrameRequestStream. The downside is that
this conversion causes an async state machine to be created per call to ReadAsync.
CopyToAsync isn't that bad because it's a single long running task.
- This change does a few things:
1. It adds the events we will replace with
pipe events to IConnectionContext and IConnectionInformation to get out of
band notifications about pipe completions.
2. It also implements those callbacks
and exposing slight changes we'll need to make once we have them. The idea is
that we can delete/replace these methods once we have the new pipe API and things
will keep working.
- This property will force Kestrel to use whatever scheduler the transport
used when write and read callbacks are fired. The default value is false so
all calls to user code including connection adapters, and the application function,
and cancellation token callbacks.
- Transports may expose configuration that changes what the transport thread is.
- Removed InternalKestrelServerOptions.cs
- Added a configurable UseSockets overload (even though there are no options yet)
- Remove RequiresDispatch from the IConnectionInformation
- This change adds the initial socket transport for Kestrel, all of the tests pass but there are still
a couple of things that aren't done yet.
- The functional tests support running both on both transports but tests aren't running for sockets right now. We need to parameterize these.
- TimeoutServerTests hard code the libuv transport, this needs to support any transport.
- There is no handling of connection stopping on application shutdown. This is being implemented in kestrel core so transports don't need to handle it. Sockets won't be the default transport until that is the case.
- Performance needs to be looked at, today the SocketTransport doesn't dispatch by default and we're not buffering in kestrel.core, this can hurt as the number of kernel calls map 1:1 with application writes.
