Subject [jira] [Resolved] (EXEC-59) execute() does not return if executed process spawned other processes
Date Mon, 10 Oct 2011 21:38:30 GMT

     [ https://issues.apache.org/jira/browse/EXEC-59?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Siegfried Goeschl resolved EXEC-59.
-----------------------------------

       Resolution: Fixed
    Fix Version/s: 1.1.1

Applied the patch from Nickolay Martinov (EXEC-57) but the timeout disguises the fact that
the process might be still runnung - therefore added a sanity check in order to throw an exception
if the the timeout for join() was exceeded.

> 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().
