dss's Issues

Set netty and akka log level from service level

See io.github.ztkmkoo.dss.core.network.rest.DssRestChannel

public class DssRestChannel {
    public DssRestChannel() {
    }

    public Channel bind(ServerBootstrap serverBootstrap, DssRestChannelProperty dssRestChannelProperty, DssRestChannelInitializer dssRestChannelInitializer) throws InterruptedException {
        Objects.requireNonNull(serverBootstrap);
        Objects.requireNonNull(dssRestChannelProperty);
        Objects.requireNonNull(dssRestChannelInitializer);
        return ((ServerBootstrap)((ServerBootstrap)serverBootstrap.channel(NioServerSocketChannel.class)).handler(new LoggingHandler(LogLevel.DEBUG))).childHandler(dssRestChannelInitializer).bind(dssRestChannelProperty.getHost(), dssRestChannelProperty.getPort()).sync().channel();
    }
}

It config netty loglevel default as debug level.
By the way, i can config the log level in the service project with create new logback.xml file(so we can see thenetty debug log), but it is necessary to make config log level possible.

How bout implementing a new log level enumeration mapping netty log level(io.netty.handler.logging.LogLevel) and let's pass the parameter to DssRestServer constructure.

Fix maven dependencies

https://github.com/ztkmkoo/dss/network/dependencies

if we set the dependency version in prpoerty, the github dependency not read it.
I dont know if it is a bug.

1, add the version directly to the dependency. => it is hard to manage the library versions
2. report bug or fix the bug (reporting here maybe https://github.community/ )
3. googling the solution
4. some way

Resolve rest dynamic url path

resolve non static path(like request param or path variable in spring framework)

Issue free ssl certification for test

Add ssl certificate module to rest server

Lets rest server can run with ssl certificate(like https protocol).
Let netty channel works with ssl context.

[BUG]Not expected response

Describe the bug
The http rest response is not expected value. for dss-0.0.2.

my test code:

public class Application {

    public static void main(String[] args) throws InterruptedException {
        DssRestServer dssRestServer = new DssRestServer("127.0.0.1", 8181);

        dssRestServer
                .addDssRestService(new MyService())
                .addDssRestService(new YourService());
        dssRestServer.start();
    }
}

public class MyService implements DssRestActorService {
    public String getName() {
        return "myService";
    }

    public String getPath() {
        return "/my/service";
    }

    public DssRestMethodType getMethodType() {
        return DssRestMethodType.GET;
    }

    public DssRestContentInfo getConsume() {
        return DssRestContentInfo.APPLICATION_JSON_UTF8;
    }

    public DssRestContentInfo getProduce() {
        return DssRestContentInfo.APPLICATION_JSON_UTF8;
    }

    public DssRestServiceResponse handling(DssRestServiceActorCommandRequest commandRequest) {
        final String myName = commandRequest.getContent();
        final MyServiceResponse response = new MyServiceResponse();
        response.setResult("My service is " + myName + " service");
        return response;
    }
}

Tell master actor the non serializable object.
Please resolve it.

[BUG]Publish 0.4.2

dss-server -> dss-core::0.0.1-SNAPSHOT
but dss-core::0.0.1-SNAPSHOT not deployed to maven central..

So the tutorial project could not find artifact io.github.ztkmkoo:dss-core:jar:0.0.1-SNAPSHOT..

Skip gpc sign for default build option

for deploy to maven central, i add maven-gpg-plugin to dss-server module.

Try to reform issue format

There are 2 issue format now.
And its so bad..

Please re-design the format and add some new useful format.

Refactory server module

add simple README.md

create new README.md file
add simple contents to it

Add jdbc data access layer interface

Add jdbc data access layer interface.
In nowaday dss system, we need impletment singleton DAO(data access object) and call it in service actor.
It is so inefficient that add a data acess layer interface and user implement it, at last we run the data access actor in the background can work greate.

Update Readme.md

update readme.md (old milestone info)

Add server module to maven repository

maven central.
Ref ~~https://jojoldu.tistory.com/161~~ => https://central.sonatype.org/pages/ossrh-guide.html

add contribute guide line

add contribute guide file

add code convention file

add code convention file

Inspect code style

Some codes do not follow the code style guide rule.
Find the mistake and patch it.

Here is the code style rule in korean.
https://github.com/ztkmkoo/dss/wiki/Code-Style(KR)

Add websocket handler and its service interface

Change group id to io.github.ztkmkoo

According to #35,
the package name(group id) should be changed to ensure greater consistency.

Add lombok.config files

Project lombok is very useful java library helps us automatically plugs into your editor and build tools.
https://projectlombok.org/

But, there are some known problems. (like @DaTa annotations, so dangerous sometimes)
Try to add an config to make it safe.

Add tutorial link to README.md

Just append tutorial link (EN + KR) to README.md

Try github package publishing

Recently, i know the github pakcage function (https://help.github.com/en/packages/using-github-packages-with-your-projects-ecosystem/configuring-apache-maven-for-use-with-github-packages). It is like maven central repository, but much easier.

I'm not sure it is safe(it was a beta version last year), but it is worth to do.

Cobertura Coverage Setting

set gradle build
set cobertura coverage config

Upgrade travis ci jdk version

On sonarqube service, the version of Java (1.8.0_252) you have used to run this analysis is deprecated and we will stop accepting it from October 2020.

So we have upgrade the jdk after #63

detail:

https://sonarcloud.io/documentation/upcoming/

The version of Java installed in the scanner environment should be upgraded to at least Java 11 by October 2020. Pre-11 versions of Java are already deprecated and scanners using them will stop functioning after October 2020. This refers specifically to the JDK or JRE installed and used in the context where your SonarCloud scanner analysis tool is running. This may be your local build environment or your CI service. Should you need some hints on how to do this, please check our help page.

Change build tool to maven

not support github dependency graph
Some issues in publishing to maven central repository

Update README.md

update README.md with new files.(CONTRIBUTION.md or CODE_OF_CONDUCT , etc..)

Add rest server tests

Please add rest server tests to dss-server module.
Check if all the functions works, if not please report the bugs.

You may need to add some http client dependency and complete the test.

Recommended tests:

basic rest test. (normal json request and its expected response)
check if contents types and encode module works well

Design network interface to accept netty modules

#54 I tried to make netty and akka work together but failed.

I have an idea that if i design Channel, EventLopp and other class, can make netty channel work on akka actor.
I will make the boss actor and working actor to implement netty bossGroup and workerGroup.

Add pull request template

Add sonarquebe badge to README.md

https://sonarcloud.io/dashboard?id=ztkmkoo_dss

resolve json and form data binding

make rest module handling content-type under below:

application/json
application/x-www-form-urlencode
multipart/form-data

Add CODE_OF_CONDUCT.md file

add CODE_OF_CONDUCT.md file with Contributor Covenant template. Will improve it later some day.

Netty http network module

network module interface
network http module implement

Serve https feature

Make Netty Handler as Akka actor

There is a big flaw in this dss server system.
Netty handler have the blocking codes with concurrent hash map.

like io.github.ztkmkoo.dss.core.network.rest.handler.DssRestHandler, i have to handle the Netty ChannelHandlerContext with the concurrent container to handling receive also send action.

Please resolve it.

It would be a big upgrade.

@Test
    public void testSsl() throws Exception {
        final PrivateKey privateKey = loadPrivateKeyFromFile(loadFromTestResources("ssl/private.der"));
        final X509Certificate certificate = loadX509CertificateFromFile(loadFromTestResources("ssl/private.crt"));

        final SslContext sslContext = SslContextBuilder.forServer(privateKey, SSL_PASSWORD, certificate).build();

        final DssRestServer dssRestServer = new DssRestServer("127.0.0.1", 8181, true, sslContext);
        dssRestServer
                .addDssRestService(new TestService("test", "/hi", DssRestMethodType.GET));

        stopDssRestServerAfterActivated(dssRestServer, 10 ,15);

        dssRestServer.start();

        assertTrue(dssRestServer.isShutdown());
    }

When I fork this repository and install, I got error in this test code
