    I have one question How to setup one connection clinet in Netty framework?
    Daniel Anderson
    @Mr00Anderson
    Easy! Uhm have you taken a look at the netty documentation? You have so many options, without knowing more about your needs it would be harder to point you further in a right direction as many codecs, exist.

    Hello!
    I am Yuvraj Agrawal currently pursuing B.Tech in CS from Indian Institute of Technology. I am currently having a course in Computer Networks and am highly interested to learn more and contribute in this field.

    I am also looking forward to GSOC 2020 and wish to contribute to your organization. I am new to open source development and am currently going through the documentation of netty. Please, help me with some minor bugs or projects to learn your code efficiently.

    Thanks

    Hello everyone! I'm a student in Engineering of Computing Systems at Politecnico di Milano (Italy).
    I'm interested in the project "Add io_uring based transport", for this year GSoC. I used Java in university project and I'm currently ending my internship as an Embedded Software Engineer where I mostly code in C.

    On GitHub I don't see any "good-first-issue" or similar tags, and looks like someone is already working on all the "help-wanted" issues. Any advice on where to start? :)
    I'm currently going through the linked PDF and Netty docs, but then I'd like to start contributing.

    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?

    @dabd
    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?

    heap: https://paste.pics/149dfc12708ebfe917297c91e9f6f861

    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...
    Christophe Bornet
    @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?
