User report 2026-05-25: launched 'npm run bot' fresh, MC server kicked
every login with "Игрок с данным никнеймом уже играет на сервере" and
the bot fell into a perpetual reconnect-then-kicked loop. Root cause:
a smoke-test supervisor from an earlier shell was still running in the
background, holding the pepa_bot session open. Two supervisors racing
on the same nickname is undefined behaviour from the server's side and
results in this exact failure mode.
Changes:
runtime/supervisor.js — acquires state/<host>/supervisor.pid before
spawning the child. If another supervisor is alive (kill -0 check), the
new one exits with a clear message telling the operator how to recover.
On SIGINT/SIGTERM/exit the lock is released; stale pidfiles are detected
when the recorded PID is no longer alive.
scripts/stop.sh — emergency cleanup helper:
- kills any supervisor or bot.js processes matching this repo
- removes pidfile + bot.sock
- reminds the operator to wait ~30s for the MC server to drop the old
session before re-launching
package.json — new `npm run stop` script.
Smoke-tested:
- first 'node runtime/supervisor.js' acquires lock, writes pid
- second call refuses with diagnostic message
- first SIGTERM ⇒ pidfile removed automatically
