FW: Buildbot Python worker diegorusso-aarch64-bigmem missing
by Diego Russo Sept. 1, 2025

Sept. 1, 2025

Hello, This is expected as Equinix (the hosting company of the machine) is decommissioning all its fleet. Arm has donated an Arm server to the PSF that will replace this worker. It’s still sitting in my office as we are waiting our IT department to make all the network adjustment to properly host it. I’ve been told that it will be in the coming weeks. I did a backup and made notes of all the changes we did, so it could be “easily” restored. Note for Pablo/Łukasz: the worker decommissioned is the same machine that ran benchmarks for speed.python.org. So, for the time being we won’t have AArch64 results in there. From the buildbot point of view, do I need to raise any PR to temporary disable the worker? --Diego From: buildbot(a)python.org <buildbot(a)python.org> Date: Friday, 29 August 2025 at 18:19 To: Subject: Buildbot Python worker diegorusso-aarch64-bigmem missing The Buildbot worker named diegorusso-aarch64-bigmem went away.

How to detect running under a buildbot?
by Jason R. Coombs Aug. 27, 2025

Aug. 27, 2025

In https://github.com/python/cpython/issues/132947, I'm struggling with an elusive issue where ResourceWarnings are emitted but only on a handful of buildbots. I'm unable to replicate the issue in GitHub CI or locally. So for a temporary workaround, I want to disable the test that surfaces the warning, but only in buildbots. I've been thusfar unsuccessful in finding a way to detect if the tests are running under buildbot. It seems that there's not a standard environment variable to signal running under buildbot. Could one be added so that it's possible to detect the environment in which its running? Secondarily, and maybe more importantly, any ideas why the behavior would be so different under this handful of <https://github.com/python/cpython/issues/132947#issuecomment-3217384492> buildbots<https://github.com/python/cpython/issues/132947#issuecomment-3217384492>?
