[Contiki-developers] Cooja Test Scripts broken

Discussion:

Hi

I have troubles running Cooja test scripts.

First, the following example script, that is deployed with Cooja, fails.

---8<---
TIMEOUT(60000);
while (true) {
log.log(time + ":" + id + ":" + msg + "\n");
YIELD();
}
--->8---

---8<---
[...]
Test script error, terminating Cooja.
[...]
TypeError: Cannot find log in object se.sics.cooja.plugins.LogScriptEngine
[...]
--->8---

Second, after pulling the recent master commit
(66868253f02b9bc2028539f23d467a0c7b3589d0), Cooja does not even build
any more:
---8<---
[javac] /home/alex/scm/contiki/tools/cooja/apps/mspsim/src/se/sics/cooja/mspmote/interfaces/CoojaM25P80.java:84: non-static variable startOffset cannot be referenced from a static context
[javac] Arrays.fill(data, CoffeeConfiguration.startOffset + offset, size, (byte)0);

[javac] System.arraycopy(bytes, 0, data, CoffeeConfiguration.startOffset + offset, size);

What's the status of Cooja Test Scripts? Is it still supported? Is there
a particular tag I should use? Any other recommendations?

Greetings

Hello,
Which version of java are you using? I had a similar error on one of my
test machines the other day because I messed up the installation - I was
using open JRE instead of the Sun version. The Sun version is no longer
available in the most recent debian packages but you can still find some
old deb files that run fine.

If that's not it, sorry ;)

Sébastien

Hi Sébastien,

thank you for sharing your experience. You were right, the JVM
implementation is the problem.

With the JVM from SUN's JDK 1.6.0_21 (32 bit) everything is fine, even
if compilation is done still done with OpenJDK's javac.

Seems like the Rhino magic uses either some non-standard features that
SUN's JVM provides or OpenJDK is not standard compliant.

Do we want to investigate this any further? Or do we simply depend on
SUN's JVM? If so, this dependency should be documented for example here

Hi,

[1] should fix your problem.

Fredrik made quite a few changes to the Cooja code. I haven't tested
those yet, so you might want to use [2].

I'm building my ppa[3] off [4], which I use for test-runs.

Cheers
Morty

Ah ok,

I didn't think of the JDK--Problem. My patch helps if Cooja times out
without any output to the serial port.
