Subject [jira] Commented: (EXEC-33) PumpStreamHandler hangs if System.in is redirect to process input stream
Date Thu, 15 Jan 2009 08:39:59 GMT

    [ https://issues.apache.org/jira/browse/EXEC-33?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12664043#action_12664043

Benjamin Bentmann commented on EXEC-33:
---------------------------------------

bq. It depends on the implementation of the JVM and the underlaying platform. On Solaris read()
will be interrupted 
Correct, additionally depends on the JVM flags passed in (UseVMInterruptibleIO).

My intention was merely to point out that we have no reliable/general/platform-independent
way of interrupting {{read()}}.

> When process input is redirected using a PumpStreamHandler, e.g.
>       PumpStreamHandler streamHanlder = new PumpStreamHandler(out, err, System.in); 
>       exec.setStreamHandler(streamHanlder);
>       MockExecuteResultHandler handler = new MockExecuteResultHandler();
>       exec.execute(cl, handler);
> the process hangs and never exit.
