Oracle Solaris buildbot
by Jakub Kulik Sept. 29, 2021

Sept. 29, 2021

Hi, We would like to offer a worker running the latest Oracle Solaris. For now, we have just a SPARC machine ready; we are looking into an Intel one as well but have no ETA for that one yet. There are still some open issues (all with PRs) that might result in test failures and one more weird failure related to leaked semaphores (which I was not able to resolve yet), but our internal buildbot is green or orange most of the time. We are committed to maintaining this bot and analyzing/reporting/possibly fixing failures found with this bot. Thanks, Jakub

Worker failures and restart
by David Edelsohn Aug. 16, 2021

Aug. 16, 2021

Yesterday, a large number of buildbots entered an error state. There has been no comment here. I see that some of the failing buildbots have recovered. I don't know if they explicitly were restarted, e.g., cstratak-RHEL8-ppc64le. The AIX and MacOS builders remain paused. I have restarted the AIX buildbot, but I cannot unpause the worker from the Buildbot scheduler. What needs to be done to resume activity? Thanks, David Traceback (most recent call last): File "/srv/buildbot/venv/lib/python3.9/site-packages/twisted/internet/defer.py", line 580, in _startRunCallbacks self._runCallbacks() File "/srv/buildbot/venv/lib/python3.9/site-packages/twisted/internet/defer.py", line 662, in _runCallbacks current.result = callback(current.result, *args, **kw) File "/srv/buildbot/venv/lib/python3.9/site-packages/twisted/internet/defer.py", line 1514, in gotResult current_context.run(_inlineCallbacks, r, g, status) File "/srv/buildbot/venv/lib/python3.9/site-packages/twisted/internet/defer.py", line 1445, in _inlineCallbacks result = current_context.run(g.send, result) --- <exception caught here> --- File "/srv/buildbot/venv/lib/python3.9/site-packages/buildbot/process/build.py", line 403, in startBuild yield self.conn.remoteStartBuild(self.builder.name) File "/srv/buildbot/venv/lib/python3.9/site-packages/buildbot/worker/protocols/pb.py", line 315, in remoteStartBuild workerforbuilder = self.builders.get(builderName) builtins.AttributeError: 'Connection' object has no attribute 'builders'

Migration of the aarch64 Fedora and RHEL buildbot to newer hardware
by Charalampos Stratakis Aug. 5, 2021

Aug. 5, 2021

Hello everyone, After a small downtime, the Fedora and RHEL aarch64 buildbots have been fully migrated from an Ampere eMAG 8180 hypervisor to an Ampere Altra 2U Mt. Jade, thanks to ARM and Equinix Metal. Since the new hypervisor comes with 160 cores, each VM will now boast 40 cores and more RAM, speeding up the test suite run (pending for https://github.com/python/buildmaster-config/pull/256 ). You'll notice 3 buildbots this time there instead of 4, as the RHEL7.6 one has been decommissioned and we are waiting for CentOS 9 Stream release. So far it seems there are no issues with connecting to the buildbot main server, but do let me know if you notice anything. -- Regards, Charalampos Stratakis Senior Software Engineer Python Maintenance Team, Red Hat

Paused workers
by David Bolen Aug. 4, 2021

Aug. 4, 2021

There seem to be a handful of workers who have been in a "paused" state for the past 24 hours or so, including my Win10 worker. Does anyone know what might be the cause? I experimented with trying to resume mine, but don't have the necessary admin rights. The worker appeared to be working normally right up until it was paused. -- David
