[PATCH] Fix xmlout option

[Omair Majid]

Hi,

The attached patch fixes the issue in mauve when running the entire test
suite with -xmlout fails:

$ java Harness -vm /usr/bin/java -xmlout xmloutputfile
No tests were run.  Possible reasons may be listed below.
Did you specify a test that doesn't exist or a folder that contains no
tests?

The bug seems to be that mauve ignores the -xmlout option and then
treats xmloutputfile as the name of the test to run. The patch adds a
case in Harness.setupHarness() so that the argument after -xmlout is
skipped (it is later checked in RunnerProcess).

Cheers,
Omair

Thanks. It took me some time to understand how this was supposed to work
with the ping-pong between Harness and RunnerProcess. I am afraid you
might be the first one in a long time that has worked with the xml
output. So don't be surprised if you find more bugs. Sorry about that.

I think you should explicitly check that args.length still has another
element like the other checks before this one. The help message implies
that the file name is optional, but it really isn't since RunnerProcess
depends on it. Could you make that change and update the help message?

Thanks,

Mark

I am just glad there is an xmlout option at all!

Good catch. Fixed patch attached. I am not sure how the help message
indicates that the file name is optional. 'filename' in '-file
[filename]' is required and so is 'millis' in '-timeout [millis]'.

O right, hmmm, how unconventional. But ok, lets keep them all the same.
Applied your patch as:

2009-02-13  Omair Majid  <omajid@...>

        * Harness.java (setupHarness): Check for -xmlout file argument.

Thanks,

Mark
