Here we phase in clang 22 as a msan and ubasan builder.

If all goes well, we'll remove clang-20 out.

Add New Build template

Hi, @grooverdan !

My suggestion is to use sg-bbw1 as a worker machine.
@fauust can you please configure it to connect to master-migration?

This is the estimated load of this patch: https://github.com/MariaDB/buildbot/actions/runs/22293877010?pr=912

note llvm/clang 22 release hasn't happened. I think we'll container rebuild when that happens for a better dev test.

Thanks, @grooverdan .
Can you tell me please when this should be scheduled for Production?
Because I can apply the changes in buildbot.dev.mariadb.org without actually merging and then you can use my server-fork to test as much as you like.

I am asking this because merging to DEV it is also a commitment to "soon will be released in buildbot production" and if this is not happening anytime soon it might get reverted if I want to do a release.

Released - hence #916

I've done the local #916 build and its passed its non-debug builds, server 10.11 on MSAN and ASAN/UBSAN. I'm not expecting massive failure.

Sure - lets take a non-merged test on DEV

If you've got time to trigger a 10.11, main, and if resources 11.4 (as a middle), I'll go through the results and report back here.

New builders get sg_bbw1 as a worker.

If all goes well, we'll remove clang-20 out.
