Full stack trace lost when using retry #7586
Description
Description
When using retry, the stack trace for the cause of the failure is lost when the retries are exhausted.
Example
import zio._
case object StackExample extends ZIOAppDefault {
override def run = {
val effect = (for {
_ <- ZIO.logInfo("Running attempt...")
_ <- foo()
} yield ())
effect.tapErrorCause(ZIO.logErrorCause(_)) orElse // preserves stack trace
effect.retry(Schedule.recurs(1)) // stack trace truncated at location of 'retry'
}
def foo(): Task[Unit] = ZIO.fail(new Exception("Triggered exception!"))
}
Outputs:

Expected Behavior
In the example above, I was expecting that the effect.retry(Schedule.recurs(1)) would have a stack trace similar to effect. Eg, something like this:
at whoco.sourcing.scripts.examples.StackExample.foo(StackExample.scala:17)
at whoco.sourcing.scripts.examples.StackExample.run.effect(StackExample.scala:10)
at whoco.sourcing.scripts.examples.StackExample.run(StackExample.scala:14)
