Subject Ant support for daemon processes
Date Tue, 05 Jun 2007 17:46:02 GMT
Hi Ant Users,

I am interested in Ant support for daemon processes, such as servers.
For example, I would like to stop an Exec or Java process on demand -
this is not possible with existing Exec and Java tasks.

Ant manual for parallel task has the following example that "represents
a typical pattern for testing a server application":

<parallel>
  <wlrun ... >
  <sequential>
    <sleep seconds="30"/>
    <junit ... >
    <wlstop/>
  </sequential>
</parallel>

Above <wlstop> is a proprietary task that only works with WL. I am
looking for a generic 'kill' task that can kill a referenced process.

The above example may look like this.

<parallel>
  <exec id='myserver'
    executable='ServerUnderTest.exe'
    ...
  <sequential>
    <sleep seconds="30"/>
    <junit ... >
    <kill id='myserver'/>
  </sequential>
</parallel>

Unlike the WL example, we are not using a proprietary stop mechanism.
The <kill> task is a generic task that calls Process.destroy(), and
works for both Exec and Java processes.

Is there anything in the Ant World on this?
    
Thank you,

--Vladimir

P.S. Another area is full support for 'spawn' attribute. Right now:

    $ ant -version
    Apache Ant version 1.6.5 compiled on June 2 2005
    $ cat t.xml
    <project>
      <exec executable="ls" spawn="true" timeout="1000"/>
    </project>
    $ ant -f t.xml
    Buildfile: t.xml
    spawn does not allow attributes related to input, output, error,
result
    spawn also does not allow timeout
    finally, spawn is not compatible with a nested I/O <redirector>
    
    BUILD FAILED
