David Tombs commented on EXEC-59:
---------------------------------
Hi Siegried. No, that's not really possible in my case. I'm working on some
code that needs to make as little assumptions as possible about the executed
process. I think this bug should be fixable. As I said in the description, I
think it's due to a bad assumption in PumpStreamHandler.stop() or nearby.
> execute() does not return if executed process spawned other processes

> Key: EXEC-59
> URL: https://issues.apache.org/jira/browse/EXEC-59
> Project: Commons Exec
> Issue Type: Bug
> Affects Versions: 1.1
> Environment: Linux x86_64
> Reporter: David Tombs
> Priority: Minor
> Attachments: spawner.sh
>
>
> When executing a process that spawns other processes,
> DefaultExecutor.execute() does not return until these secondary processes die.
> This is a problem for me because I am executing a long-running service that
> uses long-running helper processes. I want to know if the service process
> crashes (which leaves the helper processes running), but I never get any
> notice because execute() does not return. It blocks while calling
> PumpStreamHandler.stop().
