heartbeat-coroutines's Issues

수고하십니다. README 오타 수정입니다.

Suspension
누적 지연 기능을 가진 클래스입니다.

Dispatchers.Hearbeat는 Coroutine을...

Dispatchers.Hearbeat -> Dispatchers.Heartbeat

Paper 1.19 이상에서 에러가 발생합니다.

버전 & 환경

OS : Arch Linux x86_64 (6.4.8-arch1-1)
IDE : IntelliJ IDEA Ultimate 2023.1.3
JDK : openjdk 20.0.2

버그 내용

코드는 아래와 같습니다. (예제 코드와 거의 같습니다.)

override fun onEnable() {
        HeartbeatScope().launch {
            val suspension = Suspension()
            suspension.delay(3000L)
            logger.info("Hello")
        }
    }

Gradle은 아래와 같고 ShadowJar로 빌드했습니다.

plugins {
    id 'java'
    id 'org.jetbrains.kotlin.jvm' version '1.9.0'
    id 'com.github.johnrengelman.shadow' version '8.1.1'

        name = "papermc-repo"
        url = "https://repo.papermc.io/repository/maven-public/"
    }

이렇게 빌드한 플러그인을 페이퍼 1.20.1#117에서 실행시켰을 때, 아래와 같은 에러가 발생합니다.

반면 똑같은 코드를 1.18로 빌드(ShadowJar)해서 Paper 1.18.2#338에서 실행했을 때는 에러 없이 코드가 작동했습니다.

README.md 오타

README의 FSM 예시 when 부분 오류

Boolean과 Int 비교

README.md 오타

Coroutine 예제에 damageAll()이 damaegAll()로 적혀 있음

JavaPlugin 생명주기의 CoroutineScope 가 제공되지 않습니다.

문제 요약

Plugman 등을 통해서 Heartbeat Coroutines를 사용하는 플러그인을 핫리로드할 경우, Heartbeat Coroutines를 사용하는 플러그인 전부의 코루틴이 중단됩니다. 이는 Heartbeat Coroutines가 실제로는 JavaPlugin 생명주기의 CoroutineScope를 제공하는 것이 아님을 시사합니다.

문제 설명

Heartbeat Coroutines를 사용하는 플러그인을 두 개 만들어보겠습니다.

//HelloMessage1
override fun onEnable() {
    HeartbeatScope().launch {
        while(true) {
            logger.info("Hello, HeartBeat1!")
            val sus = Suspension()
            sus.delay(1000L)
        }
    }
}

//HelloMessage2
override fun onEnable() {
    HeartbeatScope().launch {
        while(true) {
            logger.info("Hello, HeartBeat2!")
            val sus = Suspension()
            sus.delay(1000L)
        }
    }
}

그리고 plugman 등으로 둘 중 하나만 리로드합니다.

[19:01:36 INFO]: [HelloMessage1] Hello, HeartBeat1!
[19:01:37 INFO]: [HelloMessage2] Hello, HeartBeat2!
[19:01:37 INFO]: [HelloMessage1] Hello, HeartBeat1!
[19:01:38 INFO]: [HelloMessage2] Hello, HeartBeat2!
[19:01:38 INFO]: [HelloMessage1] Hello, HeartBeat1!
[19:01:39 INFO]: [HelloMessage2] Hello, HeartBeat2!
[19:01:39 INFO]: [HelloMessage1] Hello, HeartBeat1!
> plugman reload HelloMessage1
[19:01:40 INFO]: [HelloMessage1] Disabling HelloMessage1 v1.0
[19:01:40 INFO]: [HelloMessage1] Loading server plugin HelloMessage1 v1.0
[19:01:40 INFO]: [HelloMessage1] Enabling HelloMessage1 v1.0
[19:01:40 INFO]: [HelloMessage1] Hello, HeartBeat1!
[19:01:40 INFO]: [PlugMan] HelloMessage1 has been reloaded.
[19:01:41 INFO]: [HelloMessage1] Hello, HeartBeat1!
[19:01:42 INFO]: [HelloMessage1] Hello, HeartBeat1!
[19:01:43 INFO]: [HelloMessage1] Hello, HeartBeat1!
[19:01:44 INFO]: [HelloMessage1] Hello, HeartBeat1!

그러면 위와 같이 HelloMessage1을 리로드하였음에 불구, HelloMessage2의 코루틴도 중단된 것을 볼 수 있습니다.
(리로드는 HelloMessage1 만 되었기 때문에, HelloMessage2의 메시지는 더 이상 나오지 않게 됩니다.)
