Ok. I have added you as a developer on https://github.com/MariaDB/server.
The way it works is that you push your changes to that repository in a
branch that starts with "bb-", eg. "bb-10.1-f4rnham". Then Buildbot will
pick up your changes and start building (can take some hours or even a day
or two in busy periods). Your builds will appear then on this page:

  https://buildbot.askmonty.org/buildbot/grid?branch=bb-10.1-f4rnham

(Please be careful about not accidentally pushing to main branches (or any
other branches) in the main repository until we've completed the review
process.)

Then when the builds are done, you can use the web interface to check for
any failures on special platforms or test configuration, and fix them as
appropriate.

Meanwhile, I will read through all of your patch, and get back to you with
comments.

Hm. The way it usually works is that the test cases SET GLOBAL debug_dbug
while the slave threads are stopped. That way there should be no races?

You might be right that there is a need for a lock, but I would prefer if
that was made as a separate change from MDEV-7502, if possible.

But it can be tricky to properly control the slave threads for testing, I
will keep this point in mind when I check your test cases, and see if I can
come up with concrete suggestions where needed.

Right, annoying but expected. The Buildbot might catch a few more that are
missed by a standard test run.
