- 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.
* 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
The format:
The trace identifier begins with connection ID and ends with a number that increments with each request per connection.
Example:
Connection ID = xyz
Request 1 = "xyz:00000001"
Request 2 = "xyz:00000002"
...
Request 15 = "xyz:0000000F"
Request 16 = "xyz:00000010"
- FIN from the client shouldn't throw
- Forced close from the server should throw
- Properly wrap connection reset exceptions and other exceptions
in IO exceptions
- This gives kestrel control over when the output closes
- Fixed one test that assumed libuv
- Dispose the connection to yield the reader
Fixes#1774
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.

- 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.`
This feature generates a unique ID per request. This unique ID can be
used in event source and logging.
Also, this change improves KestrelEventSource by moving it back into the
Kestrel.Core assembly and de-coupling from the Libuv transport. This
adds two new events, RequestStart and RequestStop, which can be used to
identify the correlation between connection ID and request trace
identifier.
Improves compliance with RFC 7230 on the expected handling of requests
that have URI or asterisk in the request target.
This means rejecting asterisk requests that are not OPTIONS and rejecting
authority-form requests taht are not CONNECT.
This also means the server will handle the path and query on targets
with absolute URIs as request-targets.
- Change most tests to use dynamic ports, rather than a fixed port obtained from GetNextPort().
- Add several new cases to `AddressRegistrationTests` and `ServerAddressFacts`.
- Remove project `test\Microsoft.AspNetCore.Server.Kestrel.TestCommon`. It's not longer needed, since only `AddressRegistrationTests` uses `GetNextPort()`.
