How to recover the coroutine's true call trace?

Question

This is a painfully familiar problem to anyone working with async APIs: when your call encounters a failure, the async library\'s private thread detects it, creates an exception

Answer 1

Just found a github issue related to this:

Stacktrace recovery ( https://github.com/Kotlin/kotlinx.coroutines/pull/792 ) and the related doc ( https://github.com/Kotlin/kotlinx.coroutines/blob/master/docs/debugging.md )

Without the caller site stacktrace, coroutine debugging is indeed painful. Hope that the "debug mode" can help. Will try and see.

Answer 2

First off all the feature is broken at the moment. If the bug is fixed I would try System.setProperty(DEBUG_PROPERTY_NAME,DEBUG_PROPERTY_VALUE_ON).

Answer 3

Kotlin plugin for IntelliJ IDEA provides this possibility since version 1.4 (for versions 1.3.8 or later of kotlinx-coroutines-core).
