    Hi, I am Lay Patel. I am a junior(3rd year) majoring in computer Science with a minor in Security and Risk Analysis, and pursuing my bachelors's degree from The Pennsylvania State University. I am interested in working with with you as a part of GSoC. I have experience in network technology. In my networking class, I designed a network architecture for a society, in a team driven environment. I have experience in python, java , C and other object oriented programming languages. I am ready to learn any new technology skills. I am interested in "Implement native event loop telemetry " project. What are the further instructions for me?

    Hi, I'm a final year student of BSc(Hons) in Computer Science at the University of Colombo. I would like to participate in GSoC. I read the Idealist and I would like to get help to continue with it. I'm doing research on web service architecture performance with Ballerina language which is built with Netty also.
    I have some basic knowledge of netty and I have some good skills in coding.
    Thank you. :)

    Hi everyone
    I am Piyush Goyal a Btech Computer Science student currently studying in Indian Institute of Technology (IIT) Mandi.
    I was going through the project list of Netty and wanted to work on Project 2 :"Regression testsuite"
    I m familiar with java/c/c++/jni and even python. I am familiar with the docker as well. I will write a proposal soon. But wanted to discuss more about the project with you first. Can you kindly summarise what the project is all about

    Hi, go and write a proposal on https://github.com/netty/netty/issues (see the others re GSoC there to understand how/why)

    Hi Guys
    I'm facing this weird exception netty/netty#10168
    any help on this?

    Is the "Netty in Action" book still relevant, or very outdated?
    kerr
    @hepin1989
    @dabd It still valid
    Dario Abdulrehman
    @dabd
    @hepin1989 thanks, I started reading the docs, and may refer to the book.
    kerr
    @hepin1989
    @dabd I translated the Chinese version, the book itself is pretty good.
    Dario Abdulrehman
    @dabd
    cool, how come after so many years the book is still relevant?
    kerr
    @hepin1989
    @dabd Because netty is well designed . but it doesnot cover the http2
    Dario Abdulrehman
    @dabd
    yep, I read about its excellent package structure

    I am stuck with netty version 4.0.33.Final but i'd like to use netty-handler-proxy which does not seem to be available for this old version of netty, is a newer version compatible with this, or am i out of luck

    Hi!
    Maybe you can help me with one problem...
    My app accumulates a lot of io.netty.util.Recycler.DefaultHandle objects in the heap. And general RAM consumption never decrease until some stop the world GC pause.
    Can you guess am I doing something wrong?

    and actually the same goes to io.netty.buffer.PooledUnsafeDirectByteBuf.... I don't understand why do I have so many such objects. I always create them using PooledByteBufAllocator.DEFAULT.directBuffer() and always release them asap. The only thing that comes to my mind is that I create ByteBuf in one thread and after that pass it to another and only after that I pass it to the netty channel...

    @cbornet

    Hi, I have a small question. If I do

    ByteBuffer buffer = ByteBuffer.allocate(10);
    ByteBuf byteBuf = Unpooled.wrappedBuffer(buffer);
    doSomethingAsync(byteBuf);
    return;

    Is there a possibility of the buffer being GC'd while being used by the async function ?

    Hi which cpu architectures are supported for netty on linux? arm and x86?
    Norman Maurer
    @normanmaurer
    aarch64 and x86 for the native transports
    for non native transports whatever is supported by java

    I'm using the LengthFieldPrepender but afterwards I have another custom encoder that adds a leading magic byte and a trailing checksum byte. The problem that I have is that the LengthFieldPrepender emits two events and that produces incorrect messages being written. How can I prevent that?

    Hi,
    I want to support HTTP/2 with TLSv1.2 and TLSv1.3. The specified Http2SecurityUtil.CIPHERS in Netty examples (https://github.com/netty/netty/blob/28e1fbd366602d8f4b50921afb2c9d5e41b94a2d/example/src/main/java/io/netty/example/http2/helloworld/server/Http2Server.java#L60) are TLSv1.2 specific (https://tools.ietf.org/html/rfc7540#section-9.2.2) and not supported by TLSv1.3. As a result when client with TLSv1.3 connects to my server, the handshake fails due to missing TLSv1.3 ciphers. How can I use the JDK TLSv1.3 ciphers in combination with Http2SecurityUtil.CIPHERS?

    Hi everyone! I'm using http client from reactor-netty and I wonder about one edge case. So I'm making http request for a large file. In the middle of the request network interface is lost. I expect to get socket exception but instead it's stuck forever. I see that I'm waiting on blocking parameterless select() call in NioEventLoop.select(). I can of course cancel the request from some watcher thread but I wonder if it can be handled in lower level. Could you please advise?

    Hi Folks, My team is using Netty webserver (Along with Spring WebFlux) for the current project. I am trying to understand how this work. Is there any diagram which explains me about its internal component? I have the following question related to this:
    1. How many requests a Netty Web server can accept? Can we cap on this?
