Hi Martin,

I have updated http://www.apis.de/pub/jdk7/ProcessImpl_md.c and http://www.apis.de/pub/jdk7/ProcessImpl_md.c.diff.

Changes:

I have also been thinking about adding tests to ProcessBuilder/Basic.java. My suggestion would be to start from the version Alan made, to get the environment issue working. I would like to stick with your test pattern of starting a java process in the test. To show that we are now using CreateProcessW, I would start a java with Runtime.getRuntime().exec() having its working dir set to a, previously created, directory containing unicode characters and do a "pwd" operation in the java child.

Although it is also possible to have the actual exe reside on a unicode path and pass unicode command line args, currently it is not possible to use this test pattern, as it needs additional modifications to the java launcher and java vm. What would you suggest to test this features, until we have a fully unicode aware version of java.exe?

Heiko, Thanks for your continuing work on this.

ProcessBuilder/Basic.java has most of the tests related to subprocesses. I can't explain a return code of 6, since the test uses 5, 7, and 8.

ProcessBuilder has a lot of infrastructure to help you write a test in this area, but it can be intimidating to newcomers (i.e. anyone but myself).

The JDK C code is quite inconsistent, but please use the style

/*

for block comments, and /* inline comments */ like this.

You need to remove the comment /* selected based on exe type */ which is no longer correct.

If you fix the style things, and get the tests to pass, and add a test for what you're actually trying to fix, I am ready to approve the change.

Martin
