    And channelinboundhandleadapter is what you're looking for I think

    @fjacobs i think for logging Netty suggests to use LoggingHandler
    and for more configuration, provide a custom implementation of this class
    thats what I did
    but it is printing these gibberish characters

    I am trying to provide a custom Logging handler to print request and response details.

    The class description says: A ChannelHandler that logs all EVENTS using a logging framework.
    Do you understand which event are you trying to print and what format it has?
    I would just start with this simple HTTP client example to print the request: https://netty.io/4.1/xref/io/netty/example/http/snoop/package-summary.html
    Then read and understand how the pipeline works https://netty.io/4.1/api/io/netty/channel/ChannelPipeline.html
    Then make a new inbound handler for the client to print the response and put it in the pipeline after the decoder handler.
    You will understand the order of the handlers and when events are send, then you can implement the LoggingHandler.

    @fjacobs thanks for providing your inputs, but I am using reactor-netty and following other examples to solve my logging usecase. Mostly I want to capture WRITE and READ events. i have created a sample, let me post that in Reactor channel.

    Hi! I am seeing a behavior that is related to what is mentioned in this post - https://stackoverflow.com/questions/13330937/play-framework-netty-does-not-release-socket.

    Basically, the number of outbound tcp connections keep growing. The post says that this was resolved by switching to tomcat.
    Anyone aware of this issue? (Iā€™m using Webflux with reactor-netty)

    Hello, everyone,
    I have developed a project that using ByteToMessageCodec to handle sticky and unpacking TCP/IP message. Although it works , but I am confused about how to Netty Framework to judge whether a ByteBuf should be dropped or accumulated.

    For example, in line 38 and 75, it should be accumulated to form a complete data, meanwhile, in line 46, it should be dropped, because it is a invalid package. I used the same way to code it "return". I think it should be coded differently.
    Thanks in advanced.

    I have read Netty source, in line 454 of ByteToMessageDecoder. It check whether ByteBuf is read, if oldInputLength equals in.readableBytes(), then ByteBuf will be discarded.
    Maybe my question is stupid. Sorry to bother you.

    Hi, we are getting timeouts in our integration tests written with Spring WebTestClient that leverages Netty when going from Netty version 4.1.42 to 4.1.43 on an "old" version of WSL. It seems to be related to the netty-transport-native-epoll artifact because downgrading that to 4.1.42 solves the issue. Does this sound familiar to anyone ?

    When a leak has been detected is the underlying buffer returned to the system? If not, why not?

    Hi šŸ‘‹
    I have been trying, without success, to create a HTTP/2 client with prior knowledge.
    My current working client does an upgrade using the following channel handler.

    new HttpClientUpgradeHandler(
            httpClientCodec,
            new Http2ClientUpgradeCodec(http2ConnectionHandler),
            65536
    );

    I have tried alot of things, but my initial attempt still seems like it should work. The handler I have tried using is:

    new Http2ConnectionHandlerBuilder()
                    .server(false)
                    .frameListener(http2ResponseHandler)
                    .frameLogger(logger)
                    .build();

    I can see an outbound settings from on both server and client, and thats where the communication ceases.
    The server is fine as I have used curl to verify it.
    If anyone has any information that would thoughts as to what might be wrong I am all ears. Thanks in advance.

    Is there any book about Netty other than "Netty in Action" ?

    hello !
    I am trying to use OCSP stapling with Boring SSL, it seems that it is not working (using a ssl client it does report that OSCPS info is not available).
    is there any to enable some kind of debug ?
    Enrico Olivelli
    @eolivelli
    enableOcsp (server side) seems to not have any effect
    both on Mac and on Linux
    Enrico Olivelli
    @eolivelli
    with a (Java) debugger I am able to check that SSLContext.enableOcsp(ctx, isClient()); is called in ReferenceCountedOpenSslContext (current Netty master), then we go into Native code
    I am using latest tcnative with boring ssl

    @eolivelli
    Is there anyway to debug errors, while contacting the OCSP responder or errors in the configuration of the trust store ?

    Hi Guys!
    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.

    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.

    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
