Learning Concurrency in Kotlin

Identifying a coroutine in the debugger

When using the debugger in IntelliJ IDEA or Android Studio, we can take advantage of the -Dkotlinx.coroutines.debug flag as well. It can facilitate the general debugging of the app, and it can be used for setting breakpoints that will happen only for a given coroutine. Let's work with the following piece of code:

val pool = newFixedThreadPoolContext(3, "myPool")val ctx = newSingleThreadContext("ctx")for (i in 0..5) {    async(pool + CoroutineName("main")) {        val year = Calendar.getInstance().get(Calendar.YEAR)        withContext(ctx + CoroutineName("inner")) {            println(year)        }    }.await()}
