- Most of the shared code is in the HttpProtocol class (former Frame)
- Virtual calls handle protocol-specific things
- Move the ProcessRequestsAsync loop to HttpProtocol
- Implement HTTP/1.x request processing in Http1Connection and HTTP/2
in Http2Stream, with Http1Connection<T> and Http2Stream<T> subclassing
those classes in order to handle the generic HttpContext parameter
- Split MessageBody into Http1MessageBody and Http2MessageBody,
with MessageBody containing shared member variables and methods
* Added initial connection middleware pipeline
- Implemented IConnectionBuilder on ListenOptions. Kept IConnectionAdapter for now.
- Delay the configure callback for ListenOptions until the server has started.
- Added ConnectionLimitMiddleware and HttpConnectionMiddleware
- Expose ConnectionAborted and ConnectionClosed on ConnectionContext and
IConnectionTransportFeature
- Updated the tests
- Removed IConnectionApplicationFeature
- Moved Application to IConnectionTransportFeature
What works:
- HTTP/2 over TLS1.2 with ALPN
- Request and response flow
- Headers are compressed and decompressed with HPACK
- Request body can be read by streams (if present)
- MVC template app with individual auth works fine
- PRIORITY frames are validated
- RST_STREAM frames are validated and abort streams
- SETTINGS frames are validated and ACKed
- PING frames are validated and ACKed
- GOAWAY frames stop connections
- WINDOW_UPDATE frames are validated
- CONTINUATION frames are sent for large header blocks
What doesn't work yet:
- Flow control in either direction
- It's not possible to encode a single header across more than one frame
- Affects only a very large header (name and value combined ~16KB long)
- Request trailers
- Response trailers
- Limits and timeouts in `KestrelServerLimits` are not enforced on HTTP/2
- HPACK use is very limited on the send side
- Literals are not Huffman-encoded
- Common headers (e.g. "server: Kestrel") are never indexed
- Honoring client settings
- Some error checking is still missing (e.g. validating incoming frame size)
