Hi there, I've noticed a behavioral change between 3.1.1 and 3.2.1 (which is also present in 3.3.0). It seems that objected are not loaded eagerly anymore. Consider the following example:

import org.koin.dsl.koinApplication
import org.koin.dsl.module

data class Tester(val id:String, val created :Long ){
    init{
        println("creating $this")
    }
}

fun main() {
    val myModule=  module(createdAtStart = true) {
        single(createdAtStart = true){
            Tester("A", System.nanoTime())
        }
    }

    val koinApplication = koinApplication {}
    val koin = koinApplication.koin
    koin.loadModules(modules = listOf(myModule))

    println("everything loaded?")

    println(koin.get<Tester>())
}

The print order changes between the mentioned versions. To me this qualifies as a bug.

already fixed in 3.2.3 I believe, for the createdAtStart

[holgerbrandl]

Thanks for the feedback. However, this patch-release does not seem yet released on maven-central -> https://mvnrepository.com/artifact/io.insert-koin/koin-core-jvm or https://mvnrepository.com/artifact/io.insert-koin/koin-core

[arnaud.giuliani]

perhaps more 3.2.2, did you try? 🤔

[holgerbrandl]

Indeed, it works fine with v3.2.2 which is also on central. Thanks for your help. Greatly appreciated!

@arnaud.giuliani I've reassed the example from above with some additional logging using koin 4.1 but the issue seems to remain

data class Tester(val created: Long = System.nanoTime()){
    init {
        println("created")
    }
}

val myModule = module(createdAtStart = true) {
    single(createdAtStart = true) {
        Tester()
    }
}

val koinApplication = koinApplication {}
val koin = koinApplication.koin
koin.loadModules(modules = listOf(myModule))

println("post-creation")


val now = System.nanoTime()

sleep(10)
now shouldBeGreaterThan koin.get<Tester>().created

The output is
> post-creation
> created
What am I doing from to enforce createAtStart?

[arnaud.giuliani]

in koinApplication you need to use createEagerInstances properties to create eager instances by hand:
