Rusi Filipov updated EXEC-65:
-----------------------------
Description:
I want to run a command from a shell script with make sure the process will be
destroyed after a timeout, especially if it asks for user input or contains
sleep commands.
{code:title=Java}
DefaultExecutor executor = new DefaultExecutor();
executor.setStreamHandler(new PumpStreamHandler(System.out, System.err));
ExecuteWatchdog watchDog = new ExecuteWatchdog(3000);
executor.setWatchdog(watchDog);
CommandLine command = new CommandLine("./client.sh");
int exitValue = executor.execute(command);
System.out.println(exitValue);
{code}
I run this code on the server like this:
{code}
java -cp .:commons-exec-1.1.jar App
{code}
*Problem 1.* I want to run {{sudo}} in order to execute a script as a different
user:
{code:title=client.sh}
#!/bin/bash
sudo -u occ02 /apps/occ02/catalina_base/bin/restart-occ.sh
{code}
In case of a misconfiguration of {{/etc/sudoers}} this prompts me for a
password.
{code}
Password:
{code}
And terminates only after about 5 minutes, not 3 seconds:
{code}
Exception in thread "main" org.apache.commons.exec.ExecuteException: Process
exited with an error: 143 (Exit value: 143)
at
org.apache.commons.exec.DefaultExecutor.executeInternal(DefaultExecutor.java:377)

at
org.apache.commons.exec.DefaultExecutor.execute(DefaultExecutor.java:147)
at App.destroy2(App.java:51)
at App.main(App.java:21)
{code}
Only if I use the {{sudo -S ...}} the process is killed after about 4 seconds:
{code}

at App.destroy2(App.java:51)
at App.main(App.java:21)
{code}
*Problem 2.* I want to prevent a too long {{sleep}}:
{code:title=client.sh}
#!/bin/bash
sleep 900
{code}
The Process just hangs! After 15 minutes the process terminates with this error:
{code}
Exception in thread "main" org.apache.commons.exec.ExecuteException: Process
exited with an error: 143 (Exit value: 143)
at
org.apache.commons.exec.DefaultExecutor.executeInternal(DefaultExecutor.java:377)

at
org.apache.commons.exec.DefaultExecutor.execute(DefaultExecutor.java:147)
at App.destroy2(App.java:51)
at App.main(App.java:21)
{code}
If I run the {{sleep}} command directly from within Java without the
shell-script, the process is destroyed on time:
{code}
DefaultExecutor executor = new DefaultExecutor();
executor.setStreamHandler(new PumpStreamHandler(System.out, System.err));
ExecuteWatchdog watchDog = new ExecuteWatchdog(3000);
executor.setWatchdog(watchDog);
CommandLine command = new CommandLine("sleep");
command.addArgument("900");
int exitValue = executor.execute(command);
System.out.println(exitValue);
{code}
{code}
Exception in thread "main" org.apache.commons.exec.ExecuteException: Process
exited with an error: 143 (Exit value: 143)

org.apache.commons.exec.DefaultExecutor.executeInternal(DefaultExecutor.java:377)

org.apache.commons.exec.DefaultExecutor.execute(DefaultExecutor.java:160)
at
org.apache.commons.exec.DefaultExecutor.execute(DefaultExecutor.java:147)
at App.destroy4(App.java:67)
at App.main(App.java:23)
{code}
These issues are currently blocking us to use commons-exec in production. The
problems were not visible when I tested on my development machine with Windows
7 64bit and JDK 1.6.0_25, 64bit.
Btw, with the {{ProcessBuilder}} from the JDK the process is destroyed in both
cases:
{code}
ProcessBuilder builder = new ProcessBuilder("./client.sh");
Process process = builder.start();
Thread.sleep(3000);
process.destroy();
{code}

Rusi
