Stephen Halter c22f8f5c59 Fix potential race in LibuvThread.StopAsync (#1756) 2017-04-24 16:47:48 -07:00
David Fowler a98581670e Schedule connection adapter reads on configured thread pool (#1741)
* Schedule connection adapter reads on configured thread pool
- This should speed up connection adapters as we don't block
new reads. It *might* also help some of the test flakiness

David Fowler 7e5604b2f5 Remove async from OnRead (#1746)
- Remove async from fast path.
- Added ApplyBackpressureAsync that pauses and resumes reading

David Fowler 71d2abed06 More clean up of LibuvConnection (#1743)
* More clean up of LibuvConnection
- Use C# 7
- Use Buffer<T>.Pin to get access to the underlying
pointer instead of using TryGetPointer.

David Fowler db44f5b672 Clean up LibuvOutputConsumer (#1744)
* Clean up LibuvOutputConsumer

* Clean up libuv connection
- Cancel all pending flushes on the input writer before
disposing the stream handle.
- Complete the pipe before disposing the socket
- Added logging for connection pause/resume.
- Added test

David Fowler feb9d1281e Tweak libuv shutdown sequence (#1735)
* Tweak libuv shutdown sequence
- Increase timeouts for thread and listener shutdowns
- Remove post.Unreference call from AllowStopRude

Nate McMaster ee9feedc27 Improve implementation of IHttpUpgradeFeature
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

David Fowler d1494224f4 Make the tests that use the Heartbeat more deterministic. (#1724)
- Added Start to Heartbeat and made OnHeartbeat internal
- Explicitly call start in tests

Stephen Halter a053ca4758 Move shutdown logic from transport to core (#1707)
* Move shutdown logic from transport to core
* Use weak references to track FrameConnections
2017-04-19 18:08:36 -07:00
Nate McMaster 7a3a731686 Refactor address binding and handle EAFNOSUPPORT
- 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)
2017-04-19 15:58:12 -07:00
David Fowler 42d82a507d Make all UvRequest objects normal GC handles (#1698)
* 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.

Cesar Blum Silveira 801a7c7652 Add copyright header to TransportSocketOptions.cs. 2017-04-17 20:47:29 -07:00
David Fowler e4af3f7e35 Expose a UseTransportThread property on KestrelServerOptions (#1695)
- 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

Stephen Halter 7aa7b3e0a9 Track connections until request processing completes
- Paves the way to allow request processing to continue during server shutdown
  even after a client disconnects.
2017-04-14 16:26:27 -07:00
Nate McMaster c08c57f764 Reject HTTP/1.1 requests that do not have a correct Host header
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

David Fowler aedd061865 Tweaks to socket transport (#1687)

Geoff Kizer efa0a48fb1 Add initial Socket transport for Kestrel (#1659)
- 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.

Nate McMaster ed4a27a827 Remove ListenOptions.Scheme and move IConnectionFilter to .Internal namespace
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.

Ben Adams d29e4d4cf0 Specialized struct generics rather than interface (#1640)
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.

David Fowler 239b691ff5 A few HttpParser changes (#1624)
- 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.
