Roadmap

Both primitives are shipped and released at 100% coverage across all six 64-bit Go arches. This page tracks what is done and what could come next.

Done

  • [x] supervisor · subreaper — SIGCHLD + Wait4(-1, WNOHANG) drain, portable Reaped events, Linux build tag with a no-op stub elsewhere.
  • [x] supervisor · process supervision — pluggable Runtime, Spec/Proc model, pid correlation, RestartNever/RestartOnFailure/RestartAlways, Stop with SIGTERM → grace → SIGKILL.
  • [x] respawn · decision core — pure Decide / DecideAfterGrace, grace debounce, sliding-window max_restarts, constant/exponential backoff, cooldown.
  • [x] respawn · Reconciler — per-unit goroutines, buffered signal fan-out, policy hot-swap, race-safe watch/unwatch.
  • [x] 100% coverage (error branches included), -race, gofmt + go vet clean, CI green on amd64, arm64, riscv64, loong64, ppc64le, s390x.

Possible next steps

  • [ ] A ready-made Runtime adapter for OCI runtimes (crun/runc) as a separate, optional sub-package (kept out of the core to preserve zero dependencies).
  • [ ] A ready-made fork+exec Runtime for plain processes.
  • [ ] Metrics/observability hooks (restart counts, cooldown entries) surfaced as a small callback interface.
  • [ ] A helper that bridges supervisor exit events into respawn signals, so the two compose out of the box.
