MockTest 下 randomImage 偶尔会抛出 SIGSGEV

Nambers commented 1 year ago

问题描述

MockTest 下

internal fun randomImage(): BufferedImage {
    val width = (500..800).random()
    val height = (500..800).random()
    val image = BufferedImage(width, height, BufferedImage.TYPE_INT_RGB)
    val graphics = image.createGraphics()
    for (x in 0 until width) {
        for (y in 0 until height) {
            graphics.color = Color(
                (0..0xFFFFFF).random()
            )
            graphics.drawRect(x, y, 1, 1)
        }
    }
    graphics.dispose()
    return image
}

的 graphics.dispose() 在一些情况下会抛出 SIGSGEV randomImage() 的 caller 是 MockNormalMember.avatarUrl 因为他第一次调用的时候会创建一个头像:

var avatarUrl: String by lateinitMutableProperty {
        runBlocking { MockImage.randomForPerson(declaredBot, id).getUrl(declaredBot) }
    }

我暂时还没找到稳定复现的方法和这个的诱因, 可能和我其他协程跑的东西有关。先在这留个 issue, 后面有时间继续看看

Workaround: 在创建 MockNormalMember 后还没开始跑其他任务(或开始测试)时调用 member.avatarUrl() 给他头像初始化

复现

第一次调用 member.avatarUrl()

在创建 MockNormalMember 对象后，在开始运行其他任务或进行测试之前，调用 member.avatarUrl() 来初始化头像。
