note to self, change PERFSCHEMA disable to WITH_UNIT_TESTS=OFF. The perfschema (non-unit) tests are probably more valuable the unit tests.

Hi,

Strongly recommend to port the builders to master-migration but if there's a sense or urgency, we can leave this for later.
Aim for code that is reusable and easy to read. If a hack cannot be avoided better ping me. The framework is still fresh and might need updates.

In https://github.com/MariaDB/buildbot/tree/dev/configuration/builders/sequences
can have a sanitizers.py where:

• define an asan_ubsan() function that will return a sequence implementing all the steps.

In master-migration/master.cfg

• define the new builders
• import the function from sanitzers.py and use it as a sequence

If you come across MTR or CMAKE options that are not defined please update:

• cmake: https://github.com/MariaDB/buildbot/blob/dev/configuration/steps/generators/cmake/options.py
• mtr: https://github.com/MariaDB/buildbot/blob/dev/configuration/steps/generators/mtr/options.py

If you come across commands you don't have please see: https://github.com/MariaDB/buildbot/tree/dev/configuration/steps/commands
Scripts used in commands go in: https://github.com/MariaDB/buildbot/tree/dev/configuration/steps/commands/scripts

To run in container:

• use the InContainer wrapper around ShellStep. Many examples in: https://github.com/MariaDB/buildbot/blob/dev/configuration/builders/sequences/release.py

should be all in #815
