Well, it never crashed. Instead, coroutines framework simply died. Well, I’m not sure that the verb “died” is the correct one in this case, but I haven’t seen anything like that in the past. At some point, after a chunk of application’s memory was leaked, coroutines simply sto...

If you have several thread pools as separate executors, they cannot share threads and resources. Inkotlinx.coroutines1.6.0, we’ve introduced the new dispatcher views API as an option to limit concurrency without creating additional threads and allocating extra resources. To start using dispatcher ...
I'm integrating coroutines with an existing Java/JVM ThreadLocal-centric function tracing system. When a plain Java stack frame launches a coroutine, it needs to get its trace from the caller. Passing it as part of the context is natural...

我们的这个创建池子调用createPlainPool的方法。也是和我们Java中使用Executors线程池一样的用法。 那么我们的推测是对的,可以下这么一个结论,kotlin的协程实际上就是我们的java的线程,更加准确的说是线程池。 我们再看看第二个参数start,类型是CoroutineStart ...
