llvm dev - Nov 2017 - PSA: debuginfo-tests workflow changing slightly

Great!  It's close to the end of the day, so I'll submit tomorrow to
make
sure everything has a chance to go fully green again to ensure I get
failure emails if it breaks.

Just an update,

At this point I've submitted and reverted this probably 6+ times, and I
don't have time to be blocked by this anymore.

I'm looking into alternatives for now, including ways of creating a new
top-level git repo such as https://git.llvm.org/git/codeview-tests.git/.

I wish there were another way, but at this point I've been working on
appeasing this for close to 2 months and I need some control over the bits
that determine whether I'm able to make forward progress.

If and when someone on the Apple side has some time to make this work with
their build infrastructure, I will be happy to revisit.

I think that the Apple folks need to either step up to fix the issue they
have, explain exactly how Zach can fix it, or we need to land this and let
it get cleaned up on Apple's side. This seems like it is starting to hold
up progress on what was a discussed and reasonable approach due to internal
infrastructure issues that folks outside of Apple cannot reasonably help
address.

In particular, Zach has created a way to minimize the impact on Apple's CI
system, and there are just bugs or challenges in getting that to work
cleanly. It really seems like if Apple has a CI challenge here, they should
step up to help address it and get this moving forward.

My two cents....

Hi Zackary,

Did you see my followup to you cfe-commits rollback:


http://lists.llvm.org/pipermail/cfe-commits/Week-of-Mon-20171120/210212.html

I think you can just remove the change to cfe/trunk/test/CMakeLists.txt and
it should work just fine.

hth...
