Am I doing something wrong?

Am I doing something wrong?

[David Herron]

Just to try out Mauve I'm running it on my OS X machine with Apple's Java. 

./configure --with-vm=/Library/Java/Home/bin/java
make
java Harness -verbose -showpasses -compile -vm java gnu.testlet

I figure since y'all haven't changed Harness.java in 2 yrs (to any 
significant change) that it must be working fine and that there's some 
kind of driver error on my part.

I get a bunch of messages saying FAIL: One of the dependencies failed to 
compile

Then it throws this:-
Exception in thread "main" java.lang.StringIndexOutOfBoundsException: 
String index out of range: -48
    at 
java.lang.AbstractStringBuilder.setLength(AbstractStringBuilder.java:146)
    at java.lang.StringBuffer.setLength(StringBuffer.java:154)
    at Harness.processFolder(Harness.java:1123)
    at Harness.processFolder(Harness.java:1153)
    at Harness.processFolder(Harness.java:1153)
    at Harness.processTest(Harness.java:899)
    at Harness.runAllTests(Harness.java:706)
    at Harness.main(Harness.java:184)


--->    sb.setLength(sb.length() - fullPath.length() - 1);

So that calculation is going negative, and inserting println's I see 
sb.length() is 0 ...

I changed that to something like this

   sb.setLength(
            (sb.length() - fullPath.length() - 1) > 0
          ? sb.length() - fullPath.length() - 1
          : 0
    );


And then this failed (line 1208)
      nextTest = nextTest.substring(0, nextTest.length() - 5);

FWIW, we run Mauve in a very similar manner on builder.classpath.org:

exec > Log.Std 2>&1
./configure --with-ecj-jar=/usr/share/java/ecj.jar --with-vm=jamvm &&
make &&
xvfb-run jamvm Harness gnu.testlet -vm jamvm -showpasses -timeout 180000

(this is testing jamvm instead of java, and uses xvfb-run to avoid
needing an X display).

I did run Mauve a while ago on OS X and I don't remember having any
problems.  Things may have changed though.

I believe twisti has done a lot of recent work on the harness, but I
don't think it's committed yet.

Actually I changed this code very much.

And today is a good day to finally commit it :-)

One thing that's wrong, but I'm not sure this is causing the exception,
you have to pass an argument to -compile option:

  -compile [yes|no]:       specify whether or not to compile the tests
before running them.  This

When I try your commandline, it simply test all testlets except the ones
I specify.

Hi David!

I also want to run nightly Mauve tests with OpenJDK and I'm having some
problems with the security checks, like:

$ java Harness -vm java -showpasses -debug gnu/testlet/java/lang/Runtime/security.class 
WARNING: running tests on 'java'.  To set the test VM, use --with-vm when
configuring or specify -vm when running the Harness.

Do you have an idea how we could fix them?  Of course I could disable
them, but...
