Bug 81949 – nrwt: crash while stopping layout test helper on apple mac lion

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[Dirk Pranke]

See: http://build.webkit.org/builders/Lion%20Intel%20Release%20%28Tests%29/builds/6721/steps/layout-test/logs/stdio

The fact that the stop call itself fails is probably a bug as well, but NRWT should deal with it.

Seems OK.

I'm confused why we'd save the MockProcess.  popen() would normaly give you a new process every time you called it. :)

Do we need to log anything here?

I see, this is why you have _proc as a member.

Probably a good idea to at least log a debug message ...

right :). It's crufty, but it's mock test code, so it's good enough for me for now. Feel free to suggest / add something cleaner.
