[PATCH 1/2] runqueue: add 'default' mc translation to mcdepends

[PATCH 1/2] runqueue: add 'default' mc translation to mcdepends

[Mark Hatle]

From: Mark Hatle <mark.hatle@amd.com>

The default mc is '' (blank), however BB_CURRENT_MC returns 'default'.
Allow a user to specify a mcdepend such as:

  mc:${BB_CURRENT_MC}:m2:recipe:task

Both '' (blank) and 'default' are now supported and have equivalent
meaning.

[PATCH 2/2] runqueue: Verify mcdepends are valid

[Mark Hatle]

From: Mark Hatle <mark.hatle@amd.com>

In order to avoid a potentially confusing backtrace, check that the mcdepend
is valid when we add it.

Add a test case to ensure invalid configurations are caught and trigger an
error.

I'm wondering if we should remove "default" entirely, it is confusing
and I'm not sure we want to complicate the code with this. I'm going to
test a patch doing that.

Cheers,

Richard

Firstly, I *really* appreciate people adding tests, its great to see so
thanks for that.

The test needs a few tweaks, just to follow best practice.

Basically you can use assertRaises() to test it raises an exception and
we should really check that it says "Command.*failed" and "mcdepends on
non-existent task.*do_invalid".

https://www.geeksforgeeks.org/test-if-a-function-throws-an-exception-in-python/

Another option would be to have a new parameter to run_bitbakecmd which
just makes it return the failure output.

Cheers,

Richard

Hi Mark,

Thanks for your patch.

I believe one of the patch from this series is responsible for some
failures we can see on the autobuilder:
