Great progress, and thanks for the update! Are you planning to base
the NetBSD native support on NativeProcessLinux? I need to migrate the
FreeBSD support to work that way still.

Re: [lldb-dev] Auditing dotest's command line options

[Zachary Turner via lldb-dev]

Hi Greg,

Take a look at dotest.py next time you get some free time and let me know
what you think.  There should be no more globals.  Everything that used to
be a global is now stored in its own module `configuration.py`, and
everything in `configuration.py` can be referenced from everywhere in the
entire test suite.

Re: [lldb-dev] Auditing dotest's command line options

[Zachary Turner via lldb-dev]

One advantage of this approach is that it makes the options available to
the entire test suite.  Even if we have no transferring going on, and we
get argparse to return us a perfectly organized structure with everything
in the right format, in order to make all the options accessible to the
rest of the test suite, we still need to stick it in a global module
somewhere.  And then you would write
`configuration.options.test_categories`, whereas with this approach we just
write `configuration.test_categories`.  It's a minor point, but I like the
shorter member access personally.

Re: [lldb-dev] Auditing dotest's command line options

[Todd Fiala via lldb-dev]

I think it's a nice improvement.

Passing the options around via the argparse results (as I do in many
programs) makes it easier to unit test, but having configuration variables
all in a module makes it really simple to find and use everywhere without
having them as globals.

Thanks for cleaning that up, Zachary!
