After upgrade has been accepted by the server:
- Reads to HttpRequest.Body always return 0
- Writes to HttpResponse.Body always throw
- The only valid way to communicate is to use the stream returned by IHttpUpgradeFeature.UpgradeAsync()
Also, Kestrel returns HTTP 400 if requests attempt to send a request body along with Connection: Upgrade
- Simplify KestrelServer by refactoring address binding into a separate class
- Use strategy pattern to implement address binding for different sceanrios
- Add fallback from binding 0.0.0.0 if binding to [::] fails (can happen if UvException with EAFNOSUPPORT is thrown)
* Make all UvRequest objects normal GC handles
- This avoids the cost of using GCHandle.Alloc per operation.
- It *does* mean that we need to explicitly dispose UvRequest objects
after using them (which we did before anyways). This change does
add a few try catch statements to make sure we always dispose the UvRequest
if there are synchronous exceptions.
- This is ~1.5% of the overhead in the benchmarks today
- Keep track of all allocated UvRequest objects with a WeakReference in DEBUG
and assert none are kept around after cleaning up.
- Fixed a leak where we don't clean up UvWriteReq objects when writing
to the named pipe.
- 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.
Add an internal API to ListenOptions to determine if an endpoint is configured to use HTTPS. This is a temporary as the design of connection adapters and configuration will churn before release.
Changed the IHttpParser interface to be generic. This lets use a struct to
get better code generation and also should allow us to inline calls back into
the handler from the parser.
- No need to test with FIN since we consider that an error
- Consolidate HTTP/1.0 and HTTP/1.1 tests that were the same except for the HTTP version
- Add a few new tests
- Renamed KestrelHttpParser to HttpParser
- Removed the generic virtual dispatch as it turns out to be an
order of magnitude slower than regular virtual dispatch. This change
means we also lose the inlining of Frame.OnStartLine and Frame.OnHeader.
* 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.

- RequestsCanBeAbortedMidRead
- RequestHeadersAreResetOnEachRequest
- UpgradeRequestIsNotKeptAliveOrChunked
- HeadersAndStreamsAreReused (rename to HeadersAndStreamsAreReusedAcrossRequests)
- Move to ResponseTests:
- Http10RequestReceivesHttp11Response (rename to Http11ResponseSentToHttp10Request)
- ZeroContentLengthSetAutomaticallyAfterNoWrites
- ZeroContentLengthSetAutomaticallyForNonKeepAliveRequests
- ZeroContentLengthNotSetAutomaticallyForHeadRequests
- ZeroContentLengthNotSetAutomaticallyForCertainStatusCodes
- ConnectionClosedAfter101Response
- ThrowingResultsIn500Response

- ThrowingAfterPartialWriteKillsConnection
- ThrowingInOnStartingResultsInFailedWritesAnd500Response
- ThrowingInOnCompletedIsLoggedAndClosesConnection
- FailedWritesResultInAbortedRequest
- NoErrorsLoggedWhenServerEndsConnectionBeforeClient
- NoResponseSentWhenConnectionIsClosedByServerBeforeClientFinishesSendingRequest
- ResponseHeadersAreResetOnEachRequest
- OnStartingCallbacksAreCalledInLastInFirstOutOrder
- OnCompletedCallbacksAreCalledInLastInFirstOutOrder
- Remove:
- RePathEscapeTests (theory data to HttpParsingData)
- ReDisconnectingClient (what was that testing?)
- Put everything in the libuv transport package under `Microsoft.AspNetCore.Server.Kestrel.Transport.Libuv.*` namespaces.
- Move stuff in Transport.Libuv/Internal/Http and Transport.Libuv/Internal/Infrastructure to Transport.Libuv/Internal (keep the Networking directory for the libuv wrappers).
- Add `Libuv` prefix to most libuv internal classes.
- Rename `KestrelEngine` to `LibuvTransport`.
- Rename `SocketOutputConsumer` to `LibuvOutputConsumer`.
- Rename `SocketOutputProducer` to `OutputProducer`.
- Fix namespaces in `Microsoft.AspNetCore.Server.Kestrel.Core.`
* Don't update consumed if we didn't see a new line
- The start line parser incorrectly updated the consumed cursor
when it attempted to find new lines across buffers. This change fixes
that and also removes passing the span by reference (which will be illegal).
- Added a unit test
