EVQUEUE(8)

📦 version 2.1, in ubuntu jammy, ubuntu noble

EVQUEUE(8) — the evQueue core engine, bestie edition 💅

okay so you're looking at the manual page for evQueue (that's the EVQUEUE(8) one, section 8, system admin vibes ✨) and honestly? iconic. let's get into it 🫶

✨ NAME ✨

evQueue — the evQueue core engine 👑

✨ SYNOPSIS ✨

evqueue [ OPTIONS ]

🦋 DESCRIPTION 🦋

okay so evQueue is the core engine daemon, and listen — it must be running if you wanna launch tasks and workflows. like, no daemon, no tasks. that's just the rules 💀

An IPC queue is what the task monitors and the evQueue daemon use to talk to each other. and the reason this is so slay is that it lets the daemon restart while tasks are still running (because the IPC queue is persistent). Missed messages get processed after the restart. So yeah — it's safe to restart the engine while workflows are running. main character behavior fr fr 🌈

💖 OPTIONS 💖

  • --config configfile — Load configuration from file configfile. that's it, that's the whole thing, she just reads her lil config file 📄
  • --daemon — Run in background. bye bestie, you're on your own now 👋
  • --ipcq-remove — Remove the IPC queue. this erases all persistent state of processes termination. In general you should never use this option unless the IPC queue has become corrupted. This can happen after an upgrade to an incompatible version when messages are pending in queue. so like… emergency button only, mkay? 🚨
  • --ipcq-stats — Display information about IPC queue. she's nosy, she wants the stats 📊
  • --ipc-terminate-tid tid — Send an IPC message to notify evQueue that the task identified by tid is terminated. The return code -1 is sent (error status). This can be used if a task is stuck (task is terminated but the message from monitor to daemon has been lost). This can happen when multiple daemons are launched with the same queue ID and the wrong daemon gets notified. messy!! 💀
  • --version — Display version information and build date. let her introduce herself 💅
