# pm2 restart vs pm2 reload
# - restart: 봇 종료 후 재시작 (몇 초간 중단)
# - reload: 새 프로세스 시작 후 기존 종료 (무중단)

# pm2 reload tsv-discord-bot
# → cluster mode에서만 진정한 무중단
# → fork mode는 reload ≈ restart

# 봇은 connection 유지가 핵심 → reload가 최소 영향

# systemd reload — 자동 재시작 + Restart=always 효과
sudo systemctl reload-or-restart tsv-tg-bot

# 또는 graceful restart 봇 코드 안에서:
# - SIGTERM 받으면 현재 요청 끝낸 후 종료
# - python-telegram-bot 자체가 graceful shutdown 지원

# 배포 후 봇 작동 X 시 빠른 롤백

# 1. 이전 커밋으로 되돌리기
ssh ubuntu@your-ip
cd ~/tsv-bot
git log --oneline -5  # 이전 커밋 확인
git checkout <prev-commit-hash>

# 2. 빌드 + 재시작
npm ci
npm run build
pm2 reload tsv-discord-bot

# 3. 작동 확인 후 origin에 force push (긴급 시만)
# 또는 새 정정 commit 푸시 (권장)
