A push reaching the mirror should take minutes, not up to six hours. All four
units now fire every 5 minutes, staggered a minute apart. Three guards make
that cadence safe:
- Scheduled runs take the release lock NON-BLOCKING (try_release_lock) and
skip the tick when a build is running. Blocking would stack one stalled
process per tick behind a long build and stampede when it finished. Manual
commands still wait, as an operator expects.
- check-versions takes the lock too, and now owns its git pull (--pull, passed
by the unit) instead of an ExecStartPre: at this cadence an unlocked pull
would swap PKGBUILDs out from under a running build.
- A failed release records .build-failed-<channel> and backs off
exponentially (10m, 20m, 40m … capped at 6h) rather than rebuilding the same
broken tree every 5 minutes. Any new commit clears the backoff, since a push
is the most likely fix.
Idle ticks exit without output so the journal keeps showing the runs that
matter, and bin/repo timers reports backoff state — a paused channel is
otherwise indistinguishable from an idle one.
Wraps systemctl list-timers with the things you actually want when checking on
the build host: per-unit enabled state, last run and whether it succeeded,
which channels have builds queued (state files), whether the release lock is
held by a live process, and any failed units. Units are discovered from
systemd/*.timer so the report cannot drift from what setup installs.
It forwards over ssh like the other host commands, so the build box's timer
state is one command away from a workstation (--local to inspect this machine).
