Siegfried Goeschl created EXEC-99: ------------------------------------- Summary: Provide a non-blocking PumpStreamHandler Key: EXEC-99 URL: https://issues.apache.org/jira/browse/EXEC-99 Project: Commons Exec Issue Type: Improvement Affects Versions: 1.3 Reporter: Siegfried Goeschl Assignee: Siegfried Goeschl Fix For: 1.4
Sometimes the current PumpStreamHandler when a process is killed but its child process streams are processed by PumpStreamHandler * Closing the processed stream does seem not work * Using Thread.interrupt() does not work * Thread.stop() is deprecated and has no effect on JDK 8 * Hence the the stream pumper thread is stuck and can't terminate * So we hand in PumpStreamHandler().stop There was a bug fix to avoid hanging forever but this leaves the pumper thread behind which could break a production system. As a work-around I propose a "NonBlockingPumpStreamHandler" * use only on worker thread to process a streams * using Thread.sleep() between processing of the streams * can be stopped safely since there are no blocking operations * it will be much slower processing the streams which could block the child process It might be a good idea to hide those implementation behind a factory -- This message was sent by Atlassian JIRA (v6.3.4#6332)
