Where should I put this patch files? Means in which directory?
> Patch to enable executing thread to return immediately when process is
> "killed" by a watchdog
> ---------------------------------------------------------------------------------------------
>
> Key: EXEC-41
> URL: https://issues.apache.org/jira/browse/EXEC-41
> Project: Commons Exec
> Issue Type: Improvement
> Affects Versions: 1.0, 1.1
> Environment: Windows XP
> Reporter: Ernest Mishkin
> Assignee: Siegfried Goeschl
> Priority: Minor
> Fix For: 1.1
>
> Attachments: EXEC-41.patch, commons-exec.patch

> This has been discussed on the commons-users mailing list. The patch intends
> to solve the following problem:
> when a process runs longer than allowed by a configured watchdog's timeout,
> the watchdog tries to destroy it and then DefaultExecutor tries to clean up
> by joining with all installed pump stream threads. Problem is, that sometimes
> the native process doesn't die and thus streams aren't closed and the stream
> threads do not complete.
> The patch provides setAlwaysWaitForStreamThreads(boolean) method in
> PumpStreamHandler. By default, alwaysWaitForStreamThreads is set to true to
> preserve the current behavior. If set to false, and process is killed by
> watchdog, DefaultExecutor's call into ErrorStreamHandler.stop will NOT join
> the stream threads and DefaultExecutor will NOT attempt to close the streams,
> so the executor's thread won't get stuck.
> Additionally, this patch fixes a small but annoying bug in
> DefaultExecuteHandler.setExitValues(int[])
