Created attachment 48933 [details] Patch

I did this because I was looking at adding support for dumping out the "list of prior test" for any test which fails. Many of our current failures are caused by test interactions. Knowing which tests were run leading up to a specific failure will help us narrow down those failures.

Comment on attachment 48933 [details] Patch > +# FIXME: Why do we need a separate class to handle --singly? Can't we just use many > +# TestShellThreads and only feed each one test? > +class SingleTestThread(TestThread): Actually, now that I look more closely at this, I'm not even sure we need that. What's weird right now is that SingleTestThread is spawned from TestShellThread. It's not clear to me why _run_test_singly doesn't just kill testshell/drt and then start it up again. Anyways, it's a FIXME. Otherwise, LGTM.

please reformat this to stay within 80 columns as per the PEP 8 style guide :) I think this patch is safe, but is basically rearranging ugly code. You put a FIXME in somewhere to just collapse the two classes, and I agree that that would probably be a better way to fix this. Is there some reason you're not doing that as part of this patch? Also, I believe this --run-singly option is only used by the valgrind bots (presumably to help ensure clean test runs); you might put a comment into the code somewhere to indicate this, so people can understand why we need this option at all.

Comment on attachment 48933 [details] Patch I'm mostly relying on Ojan and Dirk here, but this looks reasonable to me. Please fix the pep8 nits before landing. (We really need to integrate pep8 into the style elf.)

Wow. I doubt this still even applies.

This patch is too out of date to save. I'll redo this at a later date.
