--------------------------------------
Summary: Spacelift can not deal with background process invocation
Key: ARQ-1841
URL: https://issues.jboss.org/browse/ARQ-1841
Project: Arquillian
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Extension - Spacelift
Affects Versions: spacelift_1.0.0.Alpha2
Reporter: Stefan Miklosovic
Let's have this simple script:
{code}
#!/bin/sh
curpath=`dirname $0`
nohup ${curpath}/run_agent.sh $@ > /dev/null & 2>&1
{code}
I execute it like this:
{code}
public class App {
public static void main(String[] args) throws IOException {
Tasks.setDefaultExecutionServiceFactory(new DefaultExecutionServiceFactory());
System.out.println("before");
Tasks.prepare(CommandTool.class)
.programName("/bin/bash")
.parameters("-c", "/tmp/ngrinder-agent/ngrinder-agent/run_agent_bg.sh")
.execute().await();
System.out.println("after");
}
}
{code}
So it effectively does this:
{code}
/bin/bash -c "/tmp/ngrinder-agent/ngrinder-agent/run_agent_bg.sh"
{code}
However it never reaches "after" output, that process in the script is started but Spacelift does not send it to the background and it still waits untill it is finished which never happen.
Executing that script directly like following does the job:
{code}
public class App {
public static void main(String[] args) throws IOException {
Tasks.setDefaultExecutionServiceFactory(new DefaultExecutionServiceFactory());
System.out.println("before");
Runtime.getRuntime().exec("/tmp/ngrinder-agent/ngrinder-agent/run_agent_bg.sh");
System.out.println("after");
}
}
{code}
Started process survives JVM termination.
