Motivation:
SocketException and ODE are being thrown when disconnecting gracefully.
Modifications:
- dismiss async read completion if it is done on inactive channel
- do not attempt sync-reading from a socket that is not Connected
- extra: fixing echo sample with better practices
- extra: ReadListener for more natural test scenarios
- extra: tweaked nbench spec to work in-loop
Result:
No excessive errors happen during graceful shutdown
Motivation:
TlsHandler
Fix TlsHandler, optimize encryption / decryption wrt Write vs Flush semantics, optimize memory retention for sparse communication, adopt IByteBuffer.GetIoBuffers() in TlsHandler.
Modifications:
- TlsHandler is rewritten to use batch->copy->write approach instead of writing directly to SslStream in order to reduce overhead of framing / writing out everything separately.
- TlsHandler uses IByteBuffer.GetIoBuffers intead of direct array access increasing compatibility for non-array-backed buffers.
- TlsHandler and TlsHandler.MediationStream use Task semantics now when reading through SslStream.
- Extra: upgraded to NBench 2.2, xUnit 2.1.0.
- Extra: better portability for .NET Core support.
Result:
TlsHandler provides better framing and much better (x2+) performance (depends on application control of flushing).
TlsHandler operates properly in edge cases when more than one frame is accepted at once and if decrypted frame size is more than 4 KB.
TlsHandler holds only 256 byte buffer while waiting for more data to arrive off the wire.
Extra: DotNetty is almost .NET Core compatible.
