A few hours ago I deployed current Cuirass on ci.guix and its build machines. The expected benefits are: 1. Better throughput. I fixed a bug that would lead =E2=80=9Cworkers=E2= =80=9D to eventually get ignored by =E2=80=98cuirass remote-server=E2=80=99, mea= ning they would become idle until either the server or the worker is restarted=C2=B9. When I reconfigured, there were 45k pending builds (!), visible on and the vast majority of workers at were idle. We=E2=80=99re now at ~22k pending builds (okay, I cheated by canceling= ~15k from =E2=80=98emacs-team=E2=80=99, but I also restarted many builds en= masse), which are mostly non-x86. My hope is that we can get close to zero soon and have headroom for feature branches. 2. Evaluation can be triggered via POST requests, which should make things a bit more reactive and will allow us to poll repos less frequently. I submitted a support request on Savannah: . 3. Improved resilience against =E2=80=9Cevaluation storms=E2=80=9D since = =E2=80=98cuirass register=E2=80=99 now has an upper limit on the number of evaluations = that may occur in parallel. 4. Build priority handling has been restored (it had been lost recently). As a bonus, we may finally get native GNU/Hurd builds again, via the childhurds running on some of the build nodes. That=E2=80=99s it! Ludo=E2=80=99. =C2=B9 https://git.savannah.gnu.org/cgit/guix/guix-cuirass.git/commit/?id= =3D40f70d28aed55c404cca6a0760860fb4942e6bee
