* Refactoring and of FrameConnection and Frame
- Building on top of the last refactoring of FrameConnection, this change aims to clean up
the communication between the Frame and FrameConnection by removing some concepts and
being consistent about the communication between Frame and FrameConnection with or without
connection adapters. Changes include:
- Removing ConnectionLifetimeControl, ISocketOutput, StreamSocketOutput
- Moving more initialization of the frame to FrameConnection after the pipes
are setup
- OutputProducer communicates cancellation via the IPipeWriter instead of the output's IPipeReader.
- Frame always communicates via the pipes and that communications flows through the layers to the transport.
This means that each 1/2 of the adapted pipeline handles closing the right side of the transport at the
right time, propagating exceptions as necessary.
- This is how the flow looks now:
-> ->
[transport] [connection adapters] [frame]
<- <-
- Transports need to handle a ConnectionAbortedException on the output as a signal to stop
writing and end the connection. This will no longer try to drain the output but will just stop
writing and end the response immediately.
- Remove frame.Abort when cancellation on Write fails.
- Unify the connection shutdown logic
- Dispose 1/2 initialized connection adapters
#1815
- 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
Improves Kestrel to reject requests that don't conform to HTTP spec.
RFC 7230 section 5.4: "A server MUST respond with a 400 (Bad Request)
status code to any HTTP/1.1 request message that lacks a Host header
field and to any request message that contains more than one Host
header field or a Host header field with an invalid field-value."
See https://tools.ietf.org/html/rfc7230#section-5.4.
Other changes:
- update VS code settings to work better with CLI 2.0
- update tests that were subject to infinite hangs
- 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.
* Rename EngineTests to LibuvTransportTests.
* Move libuv-specific tests into their own test project.
* Move LibuvOutputConsumerTests.AllocCommitCanBeCalledAfterConnectionClose to new OutputProducerTests class and rename it to WritesNoopAfterConnectionCloses.
* Remove TransportContext from TestServiceContext.
* Make KestrelTests depend on Kestrel.Core only.
* Rename Microsoft.AspNetCore.Server.Kestrel.KestrelTests to Microsoft.AspNetCore.Server.Kestrel.Core.Tests.
* Add Microsoft.AspNetCore.Server.Kestrel.Tests test project for WebHostBuilderKestrelExtensionsTests.
* Increase socket receive timeout in MaxRequestBufferSizeTests to mitigate flakiness.
* Anything using TestServer should be a functional test.
* Move out of LibuvTransportTests tests that are not specific to LibuvTransport.
