Examples with StreamBufferingEncoder io.netty.handler.codec.http2.StreamBufferingEncoder used on opensource projects

Example 1 with StreamBufferingEncoder

use of io.netty.handler.codec.http2.StreamBufferingEncoder in project rest.li by linkedin.

the class Http2StreamCodecBuilder method build.

@Override
public Http2StreamCodec build() {
    ObjectUtil.checkNotNull(_connection, "connection");
    ObjectUtil.checkPositive(_maxHeaderSize, "maxHeaderSize");
    Http2HeadersDecoder headerDecoder = new DefaultHttp2HeadersDecoder(_maxHeaderSize, Http2CodecUtil.DEFAULT_HEADER_TABLE_SIZE, isValidateHeaders(), INITIAL_HUFFMAN_DECODE_CAPACITY);
    Http2FrameReader reader = new DefaultHttp2FrameReader(headerDecoder);
    Http2FrameWriter writer = new DefaultHttp2FrameWriter(headerSensitivityDetector());
    if (frameLogger() != null) {
        reader = new Http2InboundFrameLogger(reader, frameLogger());
        writer = new Http2OutboundFrameLogger(writer, frameLogger());
    }
    Http2ConnectionEncoder encoder = new DefaultHttp2ConnectionEncoder(_connection, writer);
    boolean encoderEnforceMaxConcurrentStreams = encoderEnforceMaxConcurrentStreams();
    if (encoderEnforceMaxConcurrentStreams) {
        if (_connection.isServer()) {
            encoder.close();
            reader.close();
            throw new IllegalArgumentException("encoderEnforceMaxConcurrentStreams: " + encoderEnforceMaxConcurrentStreams + " not supported for server");
        }
        encoder = new StreamBufferingEncoder(encoder);
    }
    Http2ConnectionDecoder decoder = new DefaultHttp2ConnectionDecoder(_connection, encoder, reader);
    super.codec(decoder, encoder);
    return super.build();
}

Example 2 with StreamBufferingEncoder

use of io.netty.handler.codec.http2.StreamBufferingEncoder in project grpc-java by grpc.

the class NettyClientHandler method newHandler.

@VisibleForTesting

    Preconditions.checkArgument(maxHeaderListSize > 0, "maxHeaderListSize must be positive");
    Preconditions.checkNotNull(ticker, "ticker");
    Http2FrameLogger frameLogger = new Http2FrameLogger(LogLevel.DEBUG, NettyClientHandler.class);
    frameReader = new Http2InboundFrameLogger(frameReader, frameLogger);
    frameWriter = new Http2OutboundFrameLogger(frameWriter, frameLogger);
    StreamBufferingEncoder encoder = new StreamBufferingEncoder(new DefaultHttp2ConnectionEncoder(connection, frameWriter));
    // Create the local flow controller configured to auto-refill the connection window.
    connection.local().flowController(new DefaultHttp2LocalFlowController(connection, DEFAULT_WINDOW_UPDATE_RATIO, true));
    // TODO(ejona): swap back to DefaultHttp2Connection with Netty-4.1.9
    Http2ConnectionDecoder decoder = new FixedHttp2ConnectionDecoder(connection, encoder, frameReader);
    Http2Settings settings = new Http2Settings();
    settings.pushEnabled(false);
    settings.initialWindowSize(flowControlWindow);
    settings.maxConcurrentStreams(0);
    settings.maxHeaderListSize(maxHeaderListSize);
    return new NettyClientHandler(decoder, encoder, settings, lifecycleManager, keepAliveManager, ticker);
