[BOLT] Rename Meta's Aarch64 workers and builders

No description provided.

This Buildbot is no longer maintained. We are coordinating with Meta on this. Our intention is to eventually replace it with an Arm-managed Buildbot (see discourse post).

[paschalis-mpeis]

Discussed with @aaupov and agreed to keep current AArch64 buildbot for now.
We'll investigate the regressions currently shown by builders/128 at a later stage and decide whether to keep it or not.

Just adding that the upcoming buildbot runs on Ubuntu 24.04.2 LTS (6.8.0-1029-aws) without regressions.

LGTM, but @gkistanova needs to update the workers file

[paschalis-mpeis]

Thanks Amir.

I've sent another patch to align with the below excerpt from the guide. Those folders are on the workers, but I'm not sure if the master uses them too. Either way, it's also more aligned with the builder's name.

Please make sure your builder name and its builddir are unique through the file.

Regarding the below:

@gkistanova needs to update the workers file

Is this a manual step that happens when the workers are updated?
And are there any further comments from @gkistanova, or should I merge?

[DavidSpickett]

This is a manual step. The new worker names need to exist in the database, otherwise they won't be allowed to connect (and repeated attempts to do so will get you IP banned, which needs to be manually removed too).

So wait for Galina to confirm what needs to be done here.

[paschalis-mpeis]

Okay. Thanks a lot for the info David.

[paschalis-mpeis]

Just to note, this patch only renames the existing Meta-Managed AArch64-Buildbot; it does not drop it.

The branch name is confusing; please ignore it. Unfortunately I can't rename it without opening a new PR.

[gkistanova]

LGTM.

[paschalis-mpeis]

Thank you both.
@aaupov, could you please reconfigure the Meta-managed buildbot to use the new name, and confirm once it's done?

[aaupov]

Done

[paschalis-mpeis]

Thanks Amir. I see that the staging buildmaster, which automatically pulls changes every 2 hours, has already picked up the merged changes. The main buildmaster, where existing bolt buildbots are attached, would need a reboot by @gkistanova as it still uses the old name bolt-worker-aarch64?
